Rachel has $80 in a savings account.The interest rate is 10%per year and is not compounded. How much interest will she earn in 1
erma4kov [3.2K]

Answer:

I = $ 8.00

Equation:

I = Prt

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 80 × 0.1 × 1 = 8

I = $ 8.00

The simple interest accumulated

on a principal of $ 80.00

at a rate of 10% per year

for 1 years is $ 8.00.

There are 72 boys and 90 girls on the math team for the next math competition Mr. Johnson would like to arrange all the students
yawa3891 [41]

Answer:

Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.

Step-by-step explanation:

Given:

Number of boys = 72

number of girls = 90

We need to arrange students in rows with equal number of only boys and only girls.

To find the maximum number (x) of boys or girls in each row, we will find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that 'x' divides both numbers evenly without a remainder.

Now to find GCF we will factorize both numbers.

72 = 2\times2\times2\times3\times3

90= 2\times 3\times 3\times 5

from above we can say that;

GCF = 2\times 3\times 3 = 18

Hence Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
