I hope this helps you



width=4/5.length



width×length =320


4/5.length ×length =320


length ^2=400


length =20


width =16

lenght - a
width - b
Area= a*b
320=ab
b=4/5a
320= 4a^{2}/5
400= a^{2}
a= \sqrt{400}
a=20
b=16

A pizza place has pizzas in 2 different sizes, with 8 different flavors for the crust, and 8 different toppings.
mamaluj [8]

Use multiplication:

2\text{ sizes}*8\text{ flavors}*8\text{ toppings}=\large\boxed{128\text{ pizzas}}

This question is basically the same as the other question of yours that I answered, so the explanation is very similar:

You can imagine the possibilities as leaves on a tree. Your tree has 2 large branches to represent the two possible sizes. Each of those branch off into 8 smaller branches, each representing a crust flavor. Each one of the smaller branches has 8 leaves to represent a different topping. Each leaf is a combination of a size, a crust flavor, and a topping, so it represents a complete pizza. Your job is to calculate the number of leaves.

5. Amy deposited $7,000 in a bank account earning 3.5% interest, compounded
Semenov [28]

Answer:

Step-by-step explanation:

Given the following data;

Principal = $7,000

Interest = 3.5% = 3.5/100 = 0.035

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 7000(1 + \frac{0.035}{n})^{nt}
