A flower garden is shaped a diameter is 34 yd A ringshaped path goes around the garden The width of the path is 5yd The is going to cover the path with sand. If one bag of sand can cover 6 ydhow many bags of sand does the gardener need? Note that sand comes by the bagthe number of bags must be a number Use the value 3.14 for
To solve this, we need to find the area of the ring-shaped path. We can find this area, by calculating the area of the whole circular garden and subtracting the area of the flower garden.
The whole garden has a diameter of 34yd for the flower garden, plus the ring-shaped path, which adds 10yd to the diameter, making a total of 44yd diameter circle.
The formula for the area of a circle is:
\(A=\pi r^2\)Where r is the radius,
Let's find the area of a circle of diameter 44yd. The radius is half the diameter, thus r = 22
\(Area\text{ }whole\text{ }garden=\pi\cdot22^2=3.14\cdot484=1519.76\text{ }yd^2\)And now, the area of the garden without the ring-shaped path. This is a circle of diameter 34yd. Thus, the radius is 17yd.
\(Area\text{ }without\text{ }path=\pi\cdot17^2=3.14\cdot289=907.46\text{ }yd^2\)If we now rest the area of the smaller circle to the area of the bigger circle, we get the area of the path:
\(Area\text{ }ring-shaped\text{ }path=1519.76-907.46=612.3\text{ }yd^2\)And to find out how many bags of san are needed, we divide the area of the path (612.3 sq yd) by the area that a single bag can cover (6 sq yd):
\(\frac{612.3}{6}=102.05\)Since we can't buy a fraction of a bag,
The answer is 103 bags of sand.

In a survey of 100 full-time students at a certain college, 62 were employed at least part-time.
Answer:
62%
Step-by-step explanation:
This one's easy to solve as a percentage because the total number was 100 to begin with. Simply divide the number of employed students by the total amount of students, 62/100, which gets 0.62, or 62%.

Rosa wants to buy a new TV priced at 499.99 The TV is on sale for 15% off but the cashier informs her that if she applies for a store credit card she can have an additional 10% off. How much will Rosa pay after the discounts and 6% tax have been applied? Write and solve an equation to find the final price.
PLEASE ANSWER AS SOON AS POSSIBLE
Answer:
$405,44
Step-by-step explanation:
First of all we have to find how much the tv cost after 15% of discount.
we can use this proportion
15 : 100 = x : 499.99
x = (15*499.99)/100 = $74.9985
then we have to subtract the initial value to the value of the discount
499.99-74.9985 = $424,9915
thanks to the card we can apply another 10%
10 : 100 = x : 424,9915
x = (424,9915 *10)/100 = $42,49915
424,9915-42,49915 = $382,49235
now we have to apply taxes
6:100 = x : 382,49235
x = $22,949541
382,49235 + 22,949541 = $405,441891
that can be rewrite as $405,44
If we want to write an equation to solve this problem we can use this
499.99 - (499.99 * 15/100) - 1/10[499.99-(499.99*15/100)] + 6/100{1/10[499.99-(499.99*15/100) = x

f(x) = 2x - 1 g(x) = 7x + 8 find (gof) (x)
Answer:
(gof)(x) = 14x + 1
Step-by-step explanation:
We can think of (gof)(x) as g(f(x)). Writing it in this form shows that we must start with the inner function and work our way to the outer function.
Essentially, the input of the inner function yields an output and the output becomes the input of the outer function.
f(x) means that the input is x and since we're given no value for x (e.g. x = so and so), the output is the original function or 2x - 1
Now, this output becomes the input for g(x):
g(2x-1) = 7(2x - 1) + 8
14x -7 + 8
(gof)(x) = 14x + 1

Answer:
\(\textsf{12)} \quad \text{a.}\;\;m \angle 1 = 107^{\circ}, \quad \text{b.}\;\;m \angle 2 = 107^{\circ}, \quad \text{c.}\;\;m \angle 3 = 73^{\circ}\)
\(\textsf{13)} \quad EC = 6\)
\(\textf{14)}\quad \text{a.}\;\;x = 33, \quad \text{b.}\;\; x = 8\)
Step-by-step explanation:
Question 12As the base angles of an isosceles trapezoid are congruent, the measures of angles E and J are the same. Therefore:
\(m\angle 3 = 73^{\circ}\)
The opposite angles of an isosceles trapezoid sum to 180°. Therefore:
\(\implies m\angle 1 + m\angle 3 = 180^{\circ}\)
\(\implies m\angle 1 + 73^{\circ} = 180^{\circ}\)
\(\implies m\angle 1 = 107^{\circ}\)
Since the base angles of an isosceles trapezoid are congruent, the measures of angles A and N are the same. Therefore:
\(m\angle 2 = 107^{\circ}\)
\(\hrulefill\)
Question 13The diagonals of isosceles trapezoid ABCD are AC and BD.
Point E is the point of intersection of the diagonals. Therefore:
\(BE + ED = BD\)
\(AE + EC = AC\)
As the diagonals of an isosceles trapezoid are the same length, BD = AC. Therefore:
\(AE + EC = BD\)
Given BD = 20 and AE = 14:
\(\implies AE + EC = BD\)
\(\implies 14 + EC = 20\)
\(\implies 14 + EC - 14 = 20 - 14\)
\(\implies EC = 6\)
\(\hrulefill\)
Question 14The midsegment of a trapezoid is a line segment that connects the midpoints of the two non-parallel sides (legs) of the trapezoid.
The formula for the midsegment of a trapezoid is:
\(\boxed{\begin{minipage}{6 cm}\underline{Midsegment of a trapezoid}\\\\$M=\dfrac{1}{2}(a+b)$\\\\where:\\ \phantom{ww}$\bullet$ $M$ is the midsegment.\\ \phantom{ww}$\bullet$ $a$ and $b$ are the parallel sides.\\\end{minipage}}\)
a) From inspection of the given trapezoid:
M = xa = 18b = 48Substitute these values into the midsegment formula and solve for x:
\(x=\dfrac{1}{2}(18+48)\)
\(x=\dfrac{1}{2}(66)\)
\(x=33\)
Therefore, the value of x is 33.
b) From inspection of the given trapezoid:
M = 15a = 22b = xSubstitute these values into the midsegment formula and solve for x:
\(15=\dfrac{1}{2}(22+x)\)
\(30=22+x\)
\(x=8\)
Therefore, the value of x is 8.

The triple integral of f(x,y,z) = x² + y² over G, using both spherical and cylindrical coordinates, is (16π/15)(√2 - √3).
What is the triple integral of the function?To sketch the solid G, we first observe that the cylinder x² + y² = 2 is a circular cylinder with radius √2, centered at the origin.
The cone z = √(x² + y²) is a double-napped cone with vertex at the origin and axis along the z-axis. The cone intersects the xy-plane in a circle of radius 1, which is contained inside the cylinder.
The solid G is the region between the cylinder and the cone, enclosed by the xy-plane.
To visualize the solid, we can first plot the cylinder and the cone in the xy-plane, as shown in image attached.
To compute the triple integral of f(x,y,z) = x² + y² over G, we can use both spherical and cylindrical coordinates.
Cylindrical Coordinates:
In cylindrical coordinates, we can write the equations of the cylinder and the cone as follows:
Cylinder: r² = 2
Cone: z = r
The limits of integration for r, θ, and z are as follows:
r: 0 to √2
θ: 0 to 2π
z: 0 to r
The triple integral of f(x,y,z) = x² + y² over G in cylindrical coordinates is:
∫∫∫ f(r,θ,z) r dz dr dθ
= ∫₀^(√2) ∫₀^(2π) ∫₀^r (r² cos²θ + r² sin²θ) dz dr dθ
= ∫₀^(√2) ∫₀^(2π) r³/2 dr dθ
= (2π/5) [√2]^5
= 16π/5
Spherical Coordinates:
In spherical coordinates, we can write the equations of the cylinder and the cone as follows:
Cylinder: ρ sinφ = √2
Cone: ρ = r
The limits of integration for ρ, θ, and φ are as follows:
ρ: √2/sinφ to √2
θ: 0 to 2π
φ: 0 to π/4
The triple integral of f(x,y,z) = x² + y² over G in spherical coordinates is:
∫∫∫ f(ρ,θ,φ) ρ² sinφ dρ dθ dφ
= ∫₀^(π/4) ∫₀^(2π) ∫_(√2/sinφ)^(√2) (ρ⁴ sin²φ cos²θ + ρ⁴ sin²φ sin²θ) sinφ dρ dθ dφ
= 2π/3 ∫_(√2/sinφ)^(√2) ρ⁴ sinφ dρ ∫₀^(π/4) sin³φ dφ
= 2π/3 [ρ⁵/5]_(√2/sinφ)^(√2) [-cosφ]₀^(π/4)
= (2π/15) [(√2)⁵ - (2/√3)(√2)⁵]
= (4π/15) [(√2)⁵ - (√6)(√2)⁴]
= (4π/15) (√2)⁴ [(√2 - √3)(√2 + √3)]
= (16π/15) (√2 - √3)

The entrance for the amusement park is $40, visitors purchase additional $2
tickets for rides, games and food. How many tickets can you buy if you
brought $100 to spend at the park?
Answer:
2 tickets because round
Step-by-step explanation:
make an equation: 100=40x+2 and solve
2.45 tickets so only two
40+40 =80
100-80=20
but 100-2=98 so there is only 18$ left so not enough for another ticket
Answer:
30 Tickets
Step-by-step explanation:
In the question, it said that $40 is the entrance fee. Then, it said that visitors purchase additional tickets for rides, games, and food. This means that EACH ticket is 2 dollars.
Hence, $40 (entrance fee) + $2 (each ticket price) x (the number of tickets spent) = 100 (total amount of money).
So, the equation should be 40 + 2x = 100, which means x = 30.
100 - 40 = 60
60/2 = 30
30 tickets can be purchased

What are the domain and range of the function f(x) = log(x-4)-3?
For the given logarithmic function, we have:
domain: (4, ∞).
range: (-∞, ∞).
How to determine the domain and range of the function?
For a function y = f(x), the domain is the set of the possible input values, and the range is the set of the possible output values.
Here we have the function:
f(x) = log(x - 4) - 3
First, we know that the range of logarithmic functions is the set of all real numbers.
We also know that the argument of logarithmic functions can only be larger than zero.
So the domain is defined by x > 4.
Then we have:
domain: (4, ∞).
range: (-∞, ∞).

The scale for this drawing is 3 in. = 8 ft. On the drawing, the length of the kitchen measures 7 in. What is the length of the actual Kitchen? Round your
answer to the nearest foot.
Answer:
19 feet
Step-by-step explanation:
First we must make the scale make sense, that is, it is in the same unit, therefore, we will pass 3 inches to feet, we know 1 foot is 12 inches, therefore:
3 inches * 1 foot / 12 inches = 0.25 feet
Which means that the real equivalence is 0.25: 8, now they are 7 inches, therefore:
7 inches * 1 foot / 12 inches = 0.583333
Now, we calculate the number of actual feet using the scale.
0.583333 * 8 / 0.25 = 18.66 feet
that is to say that the length of the current Kitchen is 19 feet if we round
What are the coordinates of the point on the directed line segment from ( − 7 , 9 ) (−7,9) to ( 3 , − 1 ) (3,−1) that partitions the segment into a ratio of 2 to 3?
The coordinates of the point on the directed line segment from (-7, 9) to (3, -1) that partitions the segment into a ratio of 2 to 3 are (-3, 5).
To find the coordinates of the point that divides the directed line segment from (-7, 9) to (3, -1) into a ratio of 2 to 3, we can use the section formula.
Let's label the coordinates of the desired point as (x, y). According to the section formula, the x-coordinate of the point is given by:
x = (2 * 3 + 3 * (-7)) / (2 + 3) = (6 - 21) / 5 = -15 / 5 = -3
Similarly, the y-coordinate of the point is given by:
y = (2 * (-1) + 3 * 9) / (2 + 3) = (-2 + 27) / 5 = 25 / 5 = 5
Therefore, the coordinates of the point that divides the line segment in a ratio of 2 to 3 are (-3, 5).
To understand this conceptually, consider the line segment as a distance from the starting point (-7, 9) to the ending point (3, -1). The ratio of 2 to 3 means that the desired point is two-thirds of the way from the starting point and one-third of the way from the ending point. By calculating the x and y coordinates using the section formula, we find that the desired point is located at (-3, 5).

Find the area A and circumference C of a circle of diameter 12 cm. Use 3.14 for . Round the result to the nearest tenth.
Answer:
Area: 113cm²
Circumference: 37.7cm
Step-by-step explanation:
to find area use the formula πr², π being Pi (3.14) and r being radius
radius = 6cm (half the diameter)
3.14 × 6² = 113.04cm²
to find the circumference use the formula πd
diameter = 12cm

Let u(x) = sin(x) and v(x) = x ^ 14 and f(x) = (u(x))/(v(x))
Explanation:
Step 1. We are given the expressions for u(x) and v(x):
\(\begin{gathered} u(x)=sin(x) \\ v(x)=x^{14} \end{gathered}\)The first two parts of the problem consist of finding the derivative of these two expressions: u'(x) and v'(x).
Step 2. To derivate u(x) we use the following rule:
\(\begin{gathered} for\text{ a function } \\ g(x)=sin(x) \\ The\text{ derivative is} \\ g^{\prime}(x)=cos(x) \end{gathered}\)which means that in this case:
\(\boxed{u^{\prime}(x)=cos(x)}\)Step 3. To derivate v(x) we use the following rule:
\(\begin{gathered} for\text{ a function} \\ g(x)=x^n \\ The\text{ derivative is} \\ g^{\prime}(x)=nx^{n-1} \end{gathered}\)In our case n=14, therefore, the derivative is:
\(\begin{gathered} v(x)=x^{14} \\ \downarrow \\ v^{\prime}(x)=14x^{14-1} \end{gathered}\)simplifying the exponent:
\(\boxed{v^{\prime}(x)=14x^{13}}\)Step 4. Now, to solve the third part of the problem, we consider the definition of f(x) given in the statement:
\(f(x)=\frac{u(x)}{v(x)}\)And to find the derivative of this function f'(x) or f', we use the quotient rule,
\(f^{\prime}=\frac{u^{\prime}v-uv^{\prime}}{v^2}\)We already know u and v from the given definitions, and we found u' and v' in 2 and 3.
So now, we substitute the known values into the quotient rule formula:
\(f^{\prime}=\frac{cos(x)(x^{14})-sin(x)(14x^{13})}{(x^{14})^2}\)Step 5. The last step is to simplify our result. We start by simplifying the exponent in the denominator:
\(f^{\prime}=\frac{cos(x)(x^{14})-s\imaginaryI n(x)(14x^{13})}{x^{28}}\)and to simplify further, divide both the numerator and denominator by x^13
\(\begin{gathered} f^{\prime}=\frac{cos(x)(x^)-s\imaginaryI n(x)(14)}{x^{15}} \\ \downarrow \\ \boxed{f^{\prime}=\frac{xcos(x)-14sin(x)}{x^{15}}} \end{gathered}\)And that is the simplified solution.
Answer:
\(\begin{gathered} u^{\prime}(x)=cos(x) \\ v^{\prime}(x)=14x^{13} \\ f^{\prime}=\frac{xcos(x)-14s\imaginaryI n(x)}{x^{15}} \end{gathered}\)Which of the following effects of a BAC of .2 percent does NOT relate to one’s driving ability?
