Expanded: (700,000) + (80,000) + (4,000)

Answer:

well, I don't have the computer in front me with this question on it, but i can explain how you would do it.

all points, or in this case vertices, are written like this : (x , y)

the x-axis is the one that lies flat and the y-axis is the one going up and down.

in this graph, the y-axis and x-axis are more than likely not centered. so where the y-axis intersects the x-axis is known as the origin. you will start at the origin for plotting all points.

to plot point A : start at the origin and count to the left 3, and then down 5 and thats point A

for point B : start at the origin, count left 1 and then down 5, that's point B

point C : start at the origin, count left 1 and then down 1, that's point C

point D : count left 3 and then down 1, that's point D

after plotting the points, you just need to play "connect the dots" and make the shape a rectangle.

Start at point A, go right point B, up to point C, left to point D then down back to point A again

Answer:

The triangles are similar.

Explanation:

Similar triangles have 3 pairs of congruent angles. In this diagram, we can see that the triangles WXP and WYZ share angle W, which is congruent to itself; therefore, they have at least 1 pair of congruent angles. We are given that angle X is congruent to angle Y, so that is a second pair of congruent angles. Finally, we know that angle P is congruent to angle Z because if two pairs of corresponding angles are congruent, then the third pair must also be congruent because the measures of the interior angles of both triangles have to add to 180°.

The sum of the geometric sequence in this problem is given as follows:

5.77.

A geometric sequence is a sequence of numbers where each term is obtained by multiplying the previous term by a fixed number, which is called the common ratio q.

The first term, the common ratio and the number of terms for this problem are given as follows:

\(a_1 = 10, q = -\frac{2}{3}, k = 8\)

The formula for the sum of the first n terms is given as follows:

\(S_n = a_1\frac{1 - r^n}{1 - r}\)

Hence the sum for this problem is given as follows:

\(S_8 = 10 \times \frac{1 - \left(-\frac{2}{3}\right)^8}{1 + \frac{2}{3}}\)

\(S_8 = 5.77\)

Answer:

slope = 2, y-intercept = 3

Step-by-step explanation:

» Concepts

All straight lines can follow the slope-intercept form, y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. The slope is the constant rate of change, and the y-intercept is where the line intersects at the y-axis.

» Application

We are asked to find the slope and y-intercept of the equation, y = 2x +3, given the form y = mx + b. As you can see, in the place of m (the slope), there is the number 2, making the slope 2. Then, in the place of b (the y-intercept), there is the number 3, making the y-intercept 3.

In this problem, we want to figure out what type of profit can be made by holding a carwash as a fundraiser.

To do the fundraiser, however, they must spend money on supplies.

Part A:

Let the total cost for supplies be represented by -$72, since it is money being spent by the team.

Let x represent the number of cars washed at a price of $8.

We can create the following equation:

Part B:

We want to know how many cars they must wash in order to make back the money spent on supplies, also known as "breaking even." To do this, the next amount should be exactly $0.

Set the equation equal to 0 and solve for x, the number of cars:

Add 72 to both sides:

Divide by 8 on both sides:

The group should was 9 cars to break even.

Part C:

If the team want to make a net profit if $1000, we can follow the same procedures. This time, let the equation be equal to $1000:

Add 72 to both sides:

Divide by 8 on both sides:

The team should wash 134 cars to earn $1000 in profit to buy the calculators.

The surface area of the wooden structure is approximately 1012 cm².

To calculate the surface area of the wooden structure, we need to find the surface area of the cone and the surface area of the hemispherical base, and then add them together.

Surface Area of the Cone:

The surface area of a cone is given by the formula:

A_{cone = \(\pi \times r_{cone} \times (r_{cone} + s_{cone})\), \(r_{cone\) is the radius of the base of the cone and \(s_{cone\) is the slant height of the cone.

The vertical height of the cone is 24 cm, and the base radius is 7 cm, we can calculate the slant height using the Pythagorean theorem:

\(s_{cone\) = \(\sqrt{(r_{cone}^2 + h_{cone}^2).\)

Using the given measurements:

\(s_{cone\) = √(7² + 24²) cm

\(s_{cone\) ≈ √(49 + 576) cm

\(s_{cone\) ≈ √625 cm

\(s_{cone\) ≈ 25 cm

Now, we can calculate the surface area of the cone:

\(A_{cone\) = π × 7 cm × (7 cm + 25 cm)

\(A_{cone\) = (22/7) × 7 cm × 32 cm

\(A_{cone\) = 704 cm²

Surface Area of the Hemispherical Base:

The surface area of a hemisphere is given by the formula:

\(A_{hemisphere\) = \(2 \times \pi \times r_{base}^2\), \(r_{base\) is the radius of the base of the hemisphere.

Given that the base radius is 7 cm, we can calculate the surface area of the hemispherical base:

\(A_{hemisphere\) = 2 × (22/7) × (7 cm)²

\(A_{hemisphere\) = (22/7) × 2 × 49 cm²

\(A_{hemisphere\) = 308 cm²

Total Surface Area:

To calculate the total surface area, we add the surface area of the cone and the surface area of the hemispherical base:

Total Surface Area = \(A_{cone} + A_{hemisphere}\)

Total Surface Area = 704 cm² + 308 cm²

Total Surface Area = 1012 cm²

The length of the diameter of the sphere is 30 cm.

The surface area of a sphere is given by the formula:

\(A = 4\pi r^2\)

where A is the surface area and r is the radius of the sphere.

We are given that the surface area of the sphere is 900π cubic cm. Therefore:

\(A = 4\pi r^2 = 900\pi\)

Dividing both sides by 4π, we get:

\(r^2 = 225\)

Taking the square root of both sides, we get:

r = 15

The diameter of the sphere is twice the radius, so:

d = 2r = 30

Therefore, the length of the diameter of the sphere is 30 cm.

Answer:

40 is 250% of 16.

Step-by-step explanation:

Let x be the unknown number.

Then we can write the proportion:

40 / x = 250 / 100

To solve for x, we can cross-multiply and simplify:

40 * 100 = 250 * x

4000 = 250x

x = 4000 / 250

x = 16

Therefore, 40 is 250% of 16.

well, that number is really "x", which oddly enough is the 100%, now, we also know that 40 is 250% of "x", hmmm

\(\begin{array}{ccll} Amount&\%\\ \cline{1-2} x & 100\\ 40& 250 \end{array} \implies \cfrac{x}{40}~~=~~\cfrac{100}{250} \\\\\\ \cfrac{ x }{ 40 } ~~=~~ \cfrac{ 2 }{ 5 }\implies 5x=80\implies x=\cfrac{80}{5}\implies x=16\)

Answer:

A. 232 in²

B. 216 in²

Step-by-step explanation:

A. Box A is a cuboid/rectangular prism.

Surface area of box A = 2(LW + LH + WH)

L = 10 in

W = 2 in

H = 8 in

Surface area = 2(10*2 + 10*8 + 2*8)

= 2(20 + 80 + 16) = 2(116)

Surface area = 232 in²

B. Surface area of B = surface area of cube

Surface area of cube = 6s²

s = 6 in

Surface area = 6(6²)

= 6(36)

= 216 in²

The most appropriate choice for function can be given by

q\(o\)p(3) =  \(\sqrt{15}+1\)

p\(o\)q(3) =  \(2\sqrt{3} + 10\)

What is function?

A function from A to B is a rule that maps to each element of A a unique element of B.

A is called the domain of the function and B is called the co domain of the function.

We can do addition, subtraction, multiplication, division and composition on functions.

Let f and g be two functions

f\(o\)g(x) = f(g(x)) and g\(o\)f(x) = g(f(x))

This is known as composition of function.

Here,

\(p(x) = x^2 + 6\\q(x) = \sqrt{x} +1\)

q\(o\)p(x) = q(p(x))

          =\(q(x^2+6)\)

          = \(\sqrt{x^2+6}+1\)

q\(o\)p(3) = \(\sqrt{3^2+6}+1\)

          = \(\sqrt{15}+1\)

p\(o\)q(x) = p(q(x))

          = p(\(\sqrt{x}+1\))

          = \((\sqrt{x}+1)^2+6\)

          = \(x + 1 + 2\sqrt{x} + 6\)

          = \(x + 2\sqrt{x} +7\)

p\(o\)q(3) = \(3 + 2\sqrt{3} +7\)
