If each of them buy an individual 10 inch pizza then each friend will eat more pizza.

Step-by-step explanation:

Solution:

Paola thinks they should each order an individual 10 inch pizza.

Diameter of 10 -inch pizza = 10 inch

We will find the radius first;

radius is half of diameter.

radius = $\frac{10}{2} =5\ inch$

Since Pizza are in Circular shape we will find the Area of the circle.

Area of pizza is equal to π times square of the radius.

framing in equation form we get;

Area of pizza = $\pi r^2 = \pi \times 5^2 = 78.54\ in^2$

Hence According to Paola if they each order 10 inch pizza then each will have $78.54\ in^2$ of Pizza

Beka says they should split 14 inch pizza.

Diameter of 14 -inch pizza = 14 inch

We will find the radius first;

radius is half of diameter.

radius = $\frac{14}{2} =7\ inch$

Since Pizza are in Circular shape we will find the Area of the circle.

Area of pizza is equal to π times square of the radius.

framing in equation form we get;

Area of pizza = $\pi r^2 = \pi \times 7^2 = 153.99\ in^2$

Now If they Split the pizza in 2 people.

Then each can have = $\frac{153.99}{2} = 77\ in^2$

Hence According to Beka if they split 14 inch pizza then each will have $77\ in^2$ of Pizza.

From Above 2 conditions we can say that.

if they each order 10 inch pizza then each will 1.54 square inch more than if they split 14 inch pizza.

Hence If each of them buy an individual 10 inch pizza then each friend will eat more pizza.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

Answer from: Quest

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
