Answer: A 16 inch pizza is $11.52

Step-by-step explanation:

$8.64 / 12 = $0.72

$0.72 x 16 = $11.52

Take the amount ($8.64) and divide it by 12 (for the 12 inch pizza) and you get $0.72 for every inch of the pizza.

Then take $0.72 and times it by 16 (for the 16 inch pizza) and you get $11.52 and there is your answer.

Andreas93 [3]

Answer:

9.74 feet

Step-by-step explanation:

the formula for finding a hypotenuse is $a^{2} + b^{2} = c^{2}$ . We can rearrange that to get: $c^2 - b^2 = a^2$ . So: 49 + b^2 = 144. We get the square root of 95, AKA around 9.74.

A grapefruit is 8% heavier than an orange, and an apple is 10% lighter than the orange.

likoan [24]

Weight of an grapefruit=weight of an orange+8% weight of an orange
weight of an apple=weight of an orange -10% weight of an orange

a.By what percentage is the grapefruit heavier than the apple?
We should find the connection between grapefruit and an apple. We know the connection between the weight of a grapefruit and an orange, we know the connection between an orange and an apple, so this means we know the connection between a grapefruit and an apple.

weight of an grapefruit=weight of an orange+8% weight of an orange
weight of an orange=weight of an apple +10% weight of an apple

-> weight of an grapefruit=weight of an apple+10% weight of an apple + 8%(weight of an apple+10% weight of an apple)= weight of an apple + 18% weight of an apple + 2% weight of an apple= weight of an apple + 20% weight of an apple

b.By what percentage is the apple lighter than the grapefruit?
weight of an grapefruit=weight of an apple + 20% weight of an apple

-> The apple ts 20% lighter than the grapefruit.
