Y is directly proportional to X^2<br> If y = 45 when x = 3 find<br> y when x = 5
postnew [5]

Answer:

Y = 125

Step-by-step explanation:

Y is directly proportional to X^2

Mathematically,

Y ∝ X²

Y = kX²

Where k = Constant of Proportionality

Step 1

If y = 45 when x = 3

We solve for k

Y = kX²

k = Y/X²

k = 45/3²

k = 45/9

k = 5

Step 2

find y when x = 5

Y = kX²

k = 5, X = 5

Hence,

Y = 5 × 5²

Y = 125

Mammals: If the number of Mammal exhibits is 25 and there are 75 total exhibits, the Mammal exhibits are 1/3 of the total exhibits at this Zoo. The ratio for 1/3 is 1:3, which is 25:75 in most complex form. That's 33.3 as a percentage, or 33.3%.

Reptiles: If the number of Reptile exhibits is 15 and there are 75 total exhibits, the reptile exhibits are 1/5 of the total exhibits here. The ratio for 1/5 is 1:5, which is 15:75 fully written out. This as a percentage is 20%.

I'll message you the other half of the answers.
