Step-by-step explanation:
Mrs. Smith made 6 ¼ dozen cookies for the birthday party. At the end of the party, there were 3 ½ dozen cookies left. How many cookies did the guests eat?
The guests in the birthday party ate 33 cookies.
How many cookies did the guests eat?We know that Mrs. Smith made 6 1/4 dozen cookies and there were 3 1/2 dozen cookies left.
Let's first convert these fractions to a common denominator of 4, so we can easily subtract them.
6 1/4 dozen = 25/4 dozen
3 1/2 dozen = 14/4 dozen
Now we can subtract the number of cookies that were left from the number of cookies that were made:
25/4 - 14/4 = 11/4 dozen
To find out how many cookies this represents, we need to multiply by the number of cookies in one dozen.
There are 12 cookies in one dozen, so:
11/4 x 12 = 33
Therefore, the guests ate 33 cookies.

Kyla finds a pair of roller blades that she would like to purchase. They are originally priced at $110 but are marked 30% off. What is the final price Kyla will pay for the roller blades if the tax rate is 5%?
To find the final price Kyla will pay for the roller blades, we first need to calculate the amount of the discount.
Discount = 30% of $110Discount = 0.30 x $110Discount = $33So Kyla will get a discount of $33 off the original price of $110.
Next, we need to calculate the pre-tax price of the roller blades after the discount.
Pre-tax price = Original price - DiscountPre-tax price = $110 - $33Pre-tax price = $77So the pre-tax price of the roller blades after the discount is $77.
Finally, we need to calculate the final price Kyla will pay, including the 5% tax.
Tax amount = 5% of $77Tax amount = 0.05 x $77Tax amount = $3.85Final price = Pre-tax price + Tax amountFinal price = $77 + $3.85Final price = $80.85Therefore, the final price Kyla will pay for the roller blades, including tax, is $80.85.what is the value of x?!?

A vacant lot is being converted into a community garden. The garden and a walkway around its perimeter have an area of 648 square feet. Find the width of the walkway if the garden measures 12 feet wide by 15 feet long.
The width cannot be negative, the width of the walkway is 6 feet. The total area of the garden and the walkway is given as 648 square feet. We know the area of the garden is length multiplied by width, which in this case is 12 feet by 15 feet, so the garden area is\(12 \times 15 = 180\) square feet.
To find the area of the walkway, we subtract the garden area from the total area. Therefore, the area of the walkway is 648 - 180 = 468 square feet.
The walkway surrounds the garden on all sides, so its length and width will be greater than the corresponding dimensions of the garden.
To calculate the width of the walkway, we can use the formula for the area of a rectangle, which is length multiplied by width. In this case, the length is 12 + 2x (twice the width of the walkway) and the width is 15 + 2x.
So, we have the equation\((12 + 2x) \times (15 + 2x) = 468\).
Expanding and rearranging the equation, we get\(4x^2 + 54x - 228 = 0.\)
Solving this quadratic equation using factoring, completing the square, or the quadratic formula, we find that x = 6 or x = -9/2.

The dimension of the rectangular of a norman window will be 1.6803*3.3606.
What is the area of Rectangle?
In any quadrilateral which have equal and parallel opposite sides is considered to be a rectangle. It is also called as a polygon with four sides and the four angles that are all 90 degrees each. A rectangle is a shape with only two dimensions. The product of the length and the breadth calculates its area. The length of the diagonals of any rectangle are equal in length. Thus, the length of the diagonals can be calculated easily using the Pythagoras theorem where, the diagonal is considered to be the hypotenuse.
Let r represents the radius, and b be the breadth.
Then, perimeter = 3.14*r+2r+2b = 12
For the dimension needed for the most light to enter we need to maximize the area.
Hence, area of the window : area of the semicircle + area of the rectangle
= \(\frac{3.14*r^2}{2} + 2rb\)
= \(12r - (\frac{3.14+4}{2}) r^2\)
A'(r) = 0
Therefore, \(r=\frac{12}{3.14+4}\) which is nearly equal to 1.6803m
From this value of r we can calculate the value of b to be;
b= 1.6803m
Thus, a= 3.606m
Thus the required dimension is : 1.6803*33606

One year, the population of the city was 264,000. Several years later it was 271,920. Find the percent increase
The percent increase in population from 264,000 to 271,920 is approximately 3%. This means that the population increased by 3% over the given time period.
To find the percent increase in population, we need to calculate the difference between the final population and the initial population, and then express that difference as a percentage of the initial population.
Given:
Initial population (P₁) = 264,000
Final population (P₂) = 271,920
To calculate the difference, we subtract the initial population from the final population:
Difference = P₂ - P₁ =\(271,920 - 264,000 = 7,920\)
To find the percent increase, we divide the difference by the initial population, then multiply by 100 to express it as a percentage:
Percent Increase = (Difference / P₁) * 100
Substituting the values:
Percent Increase =\((7,920 / 264,000) * 100\)
Calculating:
Percent Increase ≈ \(0.03 * 100\)
Percent Increase ≈ 3%
The percent increase in population from 264,000 to 271,920 is approximately 3%.

A botanist wishes to estimate the mean number of seeds for a certain fruit. She samples 18 specimens and finds the average number of seeds is 48 with a standard deviation of 14. Construct a one-sided upper-bound 80% confidence interval for the mean number of seeds for the species using the appropriate critical value to three decimal places.
Answer:
The 80% confidence interval for the mean number of seeds for the species is of 50.848 seeds.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
T interval
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 18 - 1 = 17
80% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 17 degrees of freedom(y-axis) and a confidence level(as we want the one-sided upper-bound confidence interval) of \(1 - \frac{1 - 0.8} = 0.8\). So we have T = 0.863
The margin of error is:
\(M = T\frac{s}{\sqrt{n}} = 0.863\frac{14}{\sqrt{18}} = 2.848\)
In which s is the standard deviation of the sample and n is the size of the sample.
The upper end of the interval is the sample mean added to M. So it is 48 + 2.848 = 50.848 seeds.
The 80% confidence interval for the mean number of seeds for the species is of 50.848 seeds.

A rectangular garden is to be constructed using a rock wall as one side of the garden and wire fencing for the other three sides. Given that there are 30 meters of fencing available, determine the dimensions that would create the garden of maximum area. What is the maximum possible area?
The dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is 75 square meters
What is measurement?
Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, and volume, in order to describe and quantify the properties of objects and phenomena.
Let's assume that the rock wall is the width of the garden and the wire fencing is used for the length and the other two sides. Let's denote the length of the garden as L and the width as W.
Since we have 30 meters of fencing available, the total length of wire fencing used is:
L + 2W = 30 - W
Simplifying this equation, we get:
L = 30 - 3W
The area of the garden is:
A = LW
Substituting the expression for L from the previous equation, we get:
A = W(30 - 3W)
Expanding the expression, we get:
A = 30W - 3W²
To find the maximum area, we need to take the derivative of A with respect to W and set it equal to zero:
dA/dW = 30 - 6W = 0
Solving for W, we get:
W = 5
Substituting this value back into the expression for L, we get:
L = 15
Therefore, the dimensions of the garden that create the maximum area are 5 meters by 15 meters, and the maximum possible area is:
A = 5(15) = 75 square meters

center (-4, -7), tangent to x = 2
Answer:
(x + 4)^2 + (y + 7)^2 = 36
Step-by-step explanation:
The given information describes a circle with its center at (-4, -7) and tangent to the vertical line x = 2. To determine the radius of the circle, we need to find the distance between the center and the tangent line.
The distance between a point (x1, y1) and a line Ax + By + C = 0 is given by:
d = |Ax1 + By1 + C| / sqrt(A^2 + B^2)
In this case, the equation of the line is x = 2, which can be written as 1x + 0y - 2 = 0. Therefore, A = 1, B = 0, and C = -2. The center of the circle is (-4, -7), so x1 = -4 and y1 = -7. Substituting these values into the formula, we get:
d = |1*(-4) + 0*(-7) - 2| / sqrt(1^2 + 0^2)
d = |-6| / sqrt(1)
d = 6
Therefore, the radius of the circle is 6 units. The equation of a circle with center (h,k) and radius r is given by:
(x - h)^2 + (y - k)^2 = r^2
Substituting the values we have found, we get:
(x + 4)^2 + (y + 7)^2 = 36
This is the equation of the circle that satisfies the given conditions.

ST = 9 units and TQ = 16 units.
Δ SRQ and Δ STR are equal and congruent as RT is perpendicular to hypotenuse SQ.
From similar triangles,
Δ SRQ ⩭ Δ STR ------(1)
{∵ RT 丄 Hypotenuse SQ}
Similarly, Δ SRQ and Δ RTQ are equal and congruent Δ SRQ, Δ STR and Δ RTQ are similar right-angled triangles.
Δ SRQ ⩭ Δ RTQ ------(2)
{∵ Δ SRQ, Δ STR and Δ RTQ are similar triangles}
So, this gives that the sides -
SR/ST = SQ/SR = RQ/TR
SR/9 = 25/SR = x/TR
SR² = 25 × 9
SR = 5 × 3 = 15
Now, applying the Pythagoras theorem -
SR² + RQ² = SQ²
RQ² = SQ² - SR²
RQ² = 25² - 15²

Which value of x in the equation 18x + 5 - 3 = 65 makes the equation true
Answer:
the value of x that makes the equation true is x = 3.5.
Step-by-step explanation:
To find the value of x that makes the equation 18x + 5 - 3 = 65 true, we need to simplify the equation and solve for x.
Starting with the equation:
18x + 5 - 3 = 65
First, combine like terms:
18x + 2 = 65
Next, isolate the term with x by subtracting 2 from both sides:
18x = 65 - 2
18x = 63
Finally, divide both sides of the equation by 18 to solve for x:
x = 63 / 18
x = 3.5
Therefore, the value of x that makes the equation true is x = 3.5.
The answer is:
x = 7/2 (3.5 in decimal form)Steps & work :
First, I focus only on the left side.
Combine like terms:
\(\sf{18x+5-3=65}\)
\(\sf{18x+2=65}\)
