Answer:

Wholesale: $37.50

Discount: $7.50

Explanation:

*The wholesale cost of all the bikes they sell is 30%

*Andre wants to buy a bike for $125

*If the bike is discounted by 20%

[tex]\frac{30}{100}[/tex] = [tex]\frac{x}{125}[/tex] (solve for x)

100x = 125 x 30

100x = 3750

(x =  $37.50 for the wholesale)

For the discount, we need to find 20% of 37.5

An easier way we can do is to find 10% and to multiply by 2. So, move the decimal to the left of 37.5 and we get 3.75 and multiply by 2

3.75 x 2 = 7.5 ($7.50 the discount)

Answer:

$37.50

A. The average height is greater since it has a higher mean, it also vareis less

Why the others wouldn't make sense?

Answer:

Were you listening in class

Step-by-step explanation:

Use the formula:

1/2 * Base * Height

1/2 * 24 (the base) * 7 (height)

Do the rest.

Answer:

84

Step-by-step explanation:

formula for finding area of a triangle is

1/2 x base area x height

1/2 x 24in x 7in

1/2 x 168

= 84 ( where 2 cancels 164)

Answer:

120

Step-by-step explanation:

Answer:

Angle supplementary to angle with measure of 120 is 60.

(120+x=180)

Triangle: 60+32+h = 180

h=88

Let me know if this helps!

Answer:

B) n - 21 = 7

Step-by-step explanation:

Matt started with [tex]n[/tex] lollipops, and gave 21 away and was left with 7.

This gives us the equation [tex]n - 21 = 7[/tex].

Answer:

9/3

Step-by-step explanation:

It's going up by 9 and going right by 3.

Remember it's rise over run.

Answer:

f(x)=3x-3

Step-by-step explanation:

Slope=y/x

3/1=3x

Y intercept is -3

Put the slope and y intercept together and you get 3x-3

Answer:

D. 4

Step-by-step explanation:

A straight line equals 180 degrees if there's already 140 degrees then you need 40 more to make the line true so 10 times 4 is 40 to make 140 + 40 = 180 true

Answer:

[tex]k^4+10k^2+21[/tex]

Step-by-step explanation:

[tex]k^2 (k^2)[/tex] is the same as saying [tex](k)(k)(k)(k)[/tex] and so it'll be [tex]k^4[/tex]. Combine [tex]7k^{2}[/tex] and [tex]3k^{2}[/tex] by adding them both to get [tex]10k^{2}[/tex]. Then multiply 7 by 3 to get 21. Therefore the area of the entire rectangle written in standard form as a polynomial is [tex]k^4+10k^2+21[/tex]. Write the polynomial with the highest degree being first to the lowest degree and that's how you write the polynomial properly.

Answer:

D. 15

Step-by-step explanation:

Answer:

65^2

Step-by-step explanation:

if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.

#1:

Between 8 cm and 9 cm

Work:

SA = 6s^2  

390 = 6 s^2

390/6 = 6s^2 /6

65 = s^2

sqrt(65) = s

s = 8.06

#2:

The total surface area of the triangular pyramid is 107 * square feet.

What is a triangular pyramid?

Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.

We are given that;

The length of median from outer triangle to side of the inner triangle is 8 ft

Side of inner equilateral triangle is 12 ft

Now,

First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:

a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).

a^2 + (m/2)^2 = b^2

b^2 = 6^2 + 8^2/4

b^2 = 36 + 4

b^2 = 40

b = sqrt(40)

b = 2 * sqrt(10)

So the height of the outer triangle is:

h = b * sqrt(3)/2

h = sqrt(30)

Now we can find the area of each equilateral triangle using the formula:

A = (sqrt(3)/4) * s^2

For the inner triangle:

A_inner = (sqrt(3)/4) * 12^2

A_inner = 36 * sqrt(3)

For the outer triangle:

Now we can find the area of the base, which is just the area of the inner equilateral triangle:

A_base = A_inner

A_base = 36 *

Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:

SA = A_inner + 3 * A_outer + A_base

#1 Answer:

The median height of giraffes is:

18 feet.

Step-by-step explanation:

We are given height, in feet, of 9 giraffes as:

           18, 16, 22, 14, 17, 19, 15 ,19,22

Now to find the median height of giraffes in the zoo we need to arrange the given data set in ascending order as:

14     15     16   17    18     19    19    22    22

Now we know that median is the central tendency of the data i..e it lie in the middle of the data set.

The value that lie in the middle of the given data set is:

18.

Hence, the median height of giraffes is:

18 feet.

#2 Answer:

The median of the sizes of the four parks is:

                        Option: C    33 acres.

Step-by-step explanation:

We are given area of four parks as:

27 acres    30 acres      34 acres      49 acres.

We know that the median of a data is the central tendency of a data and always lie in between or middle of the data set.

Hence, here the median will lie between 30 and 34

and hence is calculated as:

[tex]Median = \frac{30+34}{2}[/tex]

[tex]Median = \frac{64}{2}[/tex]

[tex]Median = 32[/tex]

which is close to 33.

Hence, the median size of the park is:

                             33 acres.
