First make the 2 fractions to one common denominator,
10/40 and 8/40 and add them,
10/40 + 8/40 = 18/40
simplified, 9/20
answer- 9/20 of the pizza

2/8 + 1/5 = 9/20

=0.45, but that would say how much pizza they ate in all now would it?

So, your answer is 9/20

Saj wants to go to all 19 home games at a football club.

Andreyy89

Answer:

£153

Step-by-step explanation:

If Saji bought a normal ticket for all 19 games, they would have to make 19 payments of £28. So, 28*19 would let us know that he would spend £532 in total. Then it's simply 532-379 to find the answer.

Find the volume of a hemisphere that has a diameter of 48 inches and leave your answer in terms of pie

marin [14]

Given:

Given that the diameter of the hemisphere is 48 inches.

We need to determine the volume of the hemisphere.

Radius:

The radius of the hemisphere can be determined using the formula,

$r=\frac{d}{2}$

Substituting d = 48, we get;

$r=\frac{48}{2}$

$r=24$

Thus, the radius of the hemisphere is 24 inches.

Volume of the hemisphere:

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

$V=\frac{2}{3} \pi r^3$

Substituting r = 24, we get;

$V=\frac{2}{3} \pi (24)^3$

$V=\frac{2}{3} \pi (13824)$

$V=9216 \pi \ in^3$

Thus, the volume of the hemisphere is 9216π cubic inches.
