mario paid 15,000$ for his car

Answer: $15,000

Step-by-step explanation:

This is basic proportions.

We are given that 9000=60%

Therfore 100%=X.

Using the formula of proportions, we can calculate (9000*100)/60

This gives up 15000

Therfore he paid $15,000 for his car, which is 100% of the price.

Find the slope of the line below using rise/run.

Answers

1/2 is the slope. pick 2 points and go up and then over.

Answer:

Slope: [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Slope is : [tex]\frac{rise}{run}[/tex]

If we start at the plotted point (0,0), to travel to the plotted point (2,1) following rise over run pattern you would go up 1 unit for it to correspond the set point and 2 units to the right to reach the exact point.

Answers

Answer:

A

Step-by-step explanation:

B is 180

C looks like 30-ish

D looks like 270

so A is the only one that looks to be 45

Answer:

C

Step-by-step explanation:

45/360 covers about 1/8 of the entire degress of a circle, this means the image that corresponse with be on the smaller side.

a- this seems closer to 1/4 and would not be the best match

b- this covers half, so this is much to large to correspond

c- this is the closest eyballing it, as it looks small enough to cover 1/8th as well as be properly notated

d- this is smaller and could be correct except the notation on it shows that it is going around the outside (so 360- that angle)

If you bought a pizza that is 12 inches in diameter, you get twice as much pizza as you would if you bought a pizza that is 6 inches in diameter. Is this true? Explain your thinking.

Answers

Yes

In general, if the dimensions of any two similar shapes are in the ratio m:n , then their areas are in the ratio m2:n2 .

In your case, two similar pizzas (whether circular, rectangular, or what have you) whose dimensions are in the ratio 1:1 have their areas in the ratio 2:1 . Thus, one 12 inch pizza has the same amount of pizza as two 6 inch pizzas.

Have a good day

Answer:

1

Step-by-step explanation:

Hello!

We can solve this by using the Difference of Squares formula:

(a + b)(a - b) = a² - b²

47² - 46², the numerator, is very similar to a² - b², so we can extract 47 as a, and 46 as b.

Rewrite the numerator:

47² - 46²(47 + 46)(47 - 46)(93)(1)93

We can use the same formula for the denominator the same way:

17² - 14²(17 + 14)(17 - 14)(31)(3)93

Rewrite the fraction and simplify:

[tex]\frac{93}{93}[/tex][tex]\frac11[/tex]1

The answer is 1.

Answers

Answer:

First one: 37.5

Second one: 108

Step-by-step explanation:

For the first one:

the figure shown is a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height

The triangle shown has a height of 7.5 and a base length of 10

Using this information we plug in the values into the formula.

[tex]A=\frac{7.5*10}{2} \\7.5*10=75\\\frac{75}{2} =37.5\\[/tex]

Hence the area of the figure is 37.5 square units

For the second one.

The figure shown is a parallelogram with a height of 9 and a base length of 12

The area of a parallelogram can simply be calculated by multiplying the base length by the height

So area = 9 * 12

9 * 12 = 108

Hence the area of the figure is 108 square units

Answer:

The answer to the first one is 37.5

The answer to the second one is 108

A=bh=12·9=108

Find the radius of a sphere with a volume of 972π cubic millimeters.

Answers

Answer:

The radius is 9 mm

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3  where r is the radius

972 pi  = 4/3 pi r^3

Divide each side by pi

972 = 4/3 r^3

Multiply each side by 3/4 to isolate r^3

3/4 * 972 = 4/3 * 3/4 r^3

729 = r^3

Take the cube root of each side

(729) ^ (1/3) = (r^3) ^ (1/3)

9 = r

The radius is 9 mm

Answer:

9 mm

In the figure at the right, what is m∠1 if m∠3 = 70°?
plz help i beg i will give brailist and 20 points

Answers

Answer:

m∠1 = 70°

Step-by-step explanation:

m∠1 and m∠3 are vertical angles; vertical angles are congruent (equal).

m∠1 = m∠3.

Vertically opposite angles are always equal.
Which means :
Angle 1 = Angle 3
Thus, the measure of angle 3 = 70°
▪︎Therefore, the correct option is 70

Amanda purchased a pair of shoes for $32.00 and two blouses
for $15.00 each. If the sales tax is 8.5%, what was the total
amount Amanda paid?

Answers

Answer: 3.68

Hopefully is helps

Answer: $67.27

Step-by-step explanation:

Add: $15.00+$15.00 : $30.00. Because she purchased two of them.

Then add the total to $32.00, which = $62.00.

Writing the proportion: 8.5/100  x/62.00

Multiply the sales tax by your total amount = 8.5*62.00=527.00

Then divide it by 100= 527.00/100= $5.27. <-- ( sales tax amount )

Add the sales tax to $62.00 = 67.27

Answer: $67.27
