At the end of a party, there are 3 pizzas left over. Each person will eat 2/8 of a pizza. How many people will 3 pizza feed?

Georgia [21]

First, convert 3 into a fraction with denominator 8.

(3 pizzas)(8/8 pizzas)=24/8 pizzas

Then, divide 24/8 pizzas by 2/8 pizzas per 1 person.

(24/8 pizzas)(2/8 pizzas/person)

Dividing by a fraction is the same as multiplying by the reciprocal:

(24/8)/(2/8)=(24/8)×(8/2) the 8s cancel and you are left with 24/2=12

3 pizzas will feed 12 people.

Which of the following is the surface area of the right cylinder below?

yarga [219]

Answer:

if it is TSA- 396 or 395.64

if it is CSA- 88 or 87.92

Step-by-step explanation:

r=7

h=2

TSA= 2 pi r(r+h)

=2*22/7*7*9= 396

CSA= 2 pi r h

2*22/7*7*2=88

when you use pi as 3.14 instead of 22/7 you get the answer with the decimal symbol.. in such case the TSA would be 395.64 and CSA would be 87.92

In 2006, the population of the country was 30.4 million. This represented an increase in population of 7.6 % since 2001. What w

Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

in 2001 - x million
in 2006 - 30.4 million

Population of the country as percent:

in 2001 - 100%
in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

$\dfrac{x}{30.4}=\dfrac{100}{107.6}$

Cross multiply:

$107.6\cdot x=30.4\cdot 100$

Divide by 107.6:

$x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25$

Given:

Given that the radius of the sphere is 9 cm

We need to determine the volume of the sphere.

Volume of the sphere:

Let us determine the volume of the sphere.

The volume of the sphere can be determined using the formula,

$V=\frac{4}{3} \pi r^3$

where r is the radius of the sphere.

Substituting r = 9 in the above formula, we get;

$V=\frac{4}{3} \pi (9)^3$

$V=\frac{4}{3} \pi (729)$

$V=\frac{2916}{3} \pi$

$V=972 \pi$

Thus, the volume of the sphere is 972π cm³

Hence, Option B is the correct answer.
