The ribbon was 3 1/4 inches wide and had an area of 19 1/2 square inches. What is the length of the ribbon? Please Help Will Giv

Hello!

The formula for finding area is l × w

If the area is 19 ½ inches and it was 3 ¼ inches wide, then the length will be 19 ½ ÷ 3 ¼ (Area ÷ Width)

$19 \frac{1}{2} \div 3 \frac{1}{4}$

Change both to improper fraction

$19 \frac{1}{2} = \frac{39}{2}$

$3 \frac{1}{4} = \frac{13}{4}$

$\frac{39}{2} \div \frac{13}{4}$

Keep 39/2
Change ÷ to ×
Flip 13/4 = 4/13

$\frac{39}{2} \times \frac{4}{13} = \frac{156}{26} = 6$

joey made a deposit into an account that earns 6% simple interest.After three years, joey had earned $400. How much was joey's i

Sergio [31]

Answer:

Step-by-step explanation:

To find the amount deposited, we will simply use the formula for calculating simple interest.

Simple Interest = pxrxt/100 (fraction)

Where p = principal

R= Rate

T= Time

Principal is the initial amount deposited which we are ask to find.

R is given to be 6% and T is the time which is given in years

Simple interest is the interest earned over the year which is given to be $400

Lets substitute our variable into the equation

Simple Interest = pxrxt/100 (fraction)

$400 = P × 6 × 3 / 100

$400 = 18p/100 (fraction)

We will then cross multiply

$40 000 = 18 P

To get the value of P, we divide both-side of the equation by 18

4000/18 = 18p/18 (fractions)

$2222.22 = P

P = $2222.22
