Answer:

189 students

Step-by-step explanation:

  1. 2/9 = 6th grade
  2. 2/9 = 42 students
  3. So therefore, 2/9 = 42/x
  4. Let's break down the equation above. The original fraction is 2/9. The numerator represents the 6th grade students, and the denominator represents the total number of students in the school. So, if we expand that to actual numbers in the school, it would be 42 over the total number of students in the school (represented by x).
  5. Let's solve it now in the steps below
  6. Write out the equation: \frac{2}{9} = \frac{42}{x}  
  7. Cross multiply, then divide: 9 × 42 = 378, 378 ÷ 2 = 189
  8. So, the total students in the school are 189 students.

I hope this helps!

Kiera has $20 in a savings account. The interest rate is 5%
Anuta_ua [19.1K]

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 20 × 0.05 × 2 = 2

I = $ 2.00

The simple interest accumulated

on a principal of $ 20.00

at a rate of 5% per year

for 2 years is $ 2.00.
