75 students decreased by 80%. Help plz:///

Answers

Answer 1

Answer: So,

75 students decreased by 80%. That means that 100 - 80 = 20% remain.

To find 20% of 75 students, just find 10%, which means simply moving the decimal point one place to the left.

75 --> 7.5 = 10% of 75

Therefore,
15 = 20% = 75 because 7.5 * 2 = 15

There are 15 students left.

Answer 2

Answer: Terribly sorry if i am wrong.. I believe it would be about 40%

What is the volume of a sphere when r = 9 ft

Answers

volume of a sphere is calculated using a formula:
$(4)/(3) \pi * r^(3)$

so in this case:

$(4)/(3) \pi * 9^(3)$

and taht is:

$(4)/(3) \pi *729$
$= 972 \pi$

Hope it helps you! :)

What is the pattern as the exponents decrease?

What is the value of each variable in the table?
a =
b =
c =

Answers

The pattern of the exponent's decrease should be that it divided by 8.

The value of each variable should be like

a = 1

b = $1/ 8$

c = $1/ 64$

Calculation of the pattern and the value:

The pattern of the exponent's decrease should be that it divided by 8.

The value of each variable should be like

a = 1

b = $1/ 8$

c = $1/ 64$

In this way it should be determined.

Answer:

Do not use $a^(2) + b^(2) = c^(2)$ that's to solve the hypotenuse of a triangle.

The difference is 31 cm³

Step-by-step explanation:

To solve the volume a cube it's a³

5.7³ = 185.193

I'm assuming to round to the nearest whole number so the difference would be

216 - 185 = 31

What is 3.6 as fraction?

Answers

3.6 is a fraction greater than one, since 3 is 3 wholes, the 6 is the numerator, is the denominator. So 3.6 can be written as 36/10 or 18/5, if you want do write it in mixed number it would be 3 3/5.

18/5 or 3 and 3/5. I did this on my calculator. If you have one of the graphing ones, just use decimal to fraction.
