If 7056 divided X is equals to 42; y divided 112 =8, then x/y is

Alekssandra [29.7K]

Step-by-step explanation:

given

$\frac{7056}{x} = 42 \\ \\ 42x = 7056 \\ x = \frac{7056}{42} \\ = 168$

also given

$\frac{y}{112} = 8 \\ y = 8(112) \\ = 896$

therefore

$\frac{x}{y} = \frac{168}{896} \\ = \frac{3}{16}$

Jacob invested $300 in a savings account and earned $81 in simple interest at the end of 9 years. what was the interest rate

Brilliant_brown [7]

Answer:

Step-by-step explanation:

We use the simple interest equation of A=P(1+rt).

A-the total amount with interest earned

P-the initial amount or principal

r-rate

t-time in years

We substitute the values P=300, A=381, and t=9. We then solve for r.

$381=300(1+9r)$

We divide both sides by 300.

$\frac{381}{300}=\frac{300(1+9r)}{300}$

Simplify.

$1.27=1+9r$

We subtract 1 from both sides.

$1.27-1=1-1+9r$

Simplify.

$0.27=9r$

We divide by 9.

$\frac{0.27}{9}=\frac{9r}{9}$

r=0.03

We need to convert the decimal to a percentage by multiplying by 100.

The interest rate is 3%.

What is 33 and 67 in it's simplest ratio

murzikaleks [220]

To find the simplest ratio, you must find the largest number they can both be divided by (greatest common factor, or GCF). However, 67 is a prime number, meaning its only factors are 67 and 1. That means there are no GCFs here other than 1, so, the simplest ratio here would be 33 over 67, or 33/67 in computer text. easy peasy!

the length of a pool is 10 meters more than twice the width. The area of the pool is 1500 square meters. What is the length of t

Arte-miy333 [17]

Let's make the length L and the width w. So, here's what we know:

L = 2w + 10

Lw = 1500

Substitute L in as 2w + 10:

w(2w + 10) = 1500.

Simplify.

2w squared +10w = 1500

Make it a quadratic equation, w = 25 or -30. Since it can't be negative, w = 25.

1500/25 = 60.

Length = 60
Width = 25
