You saved 850$ from your summer job last summer. You put it in a account that earns simple interest each month. After 9 Months your account is worth 1,003$. What percent interest did you earn each month?

Answers

Answer 1

Answer: Interest earned=$1003−$850=$153
Principal=$850
Time=9 months
Rate=Interest per month

Use the formula to solve for interest: (Interest)=(Principal)×(Rate)×(Time)
153 = 850 × R × 9
Simplify.
153 = 7650 × R
Divide both sides by 7650.
0.02 = Rate
She earned 2% interest each month.

Margot wants to use partial products to find 22x17. Write the number in the boxes to show 22x17

Answers

154
( 7×2 + 7×2+1 )

22
( 1×2 is 2 and 1×2 is 2 )

Add all together and get 174. :))

Final answer:

To solve 22x17 using partial products, break down 22 and 17 into the sums of their place values. Find the partial products and add them together for a total of 374.

Explanation:

To solve the math problem 22 x 17 using partial products, you first break down the numbers 22 and 17 into their tens and ones place values. Thus, 22 is 20 + 2, and 17 is 10 + 7.

Then, you find the four partial products: (20 x 10), (20 x 7), (2 x 10), (2 x 7) which are 200, 140, 20, and 14 respectively.

You then add those products together: 200 + 140 + 20 + 14 = 374. So, 22 x 17 equals 374.

There are two identical figures with all sides of equal length. The combined perimeter of the figures is 80 centimeters. What shape are the figures? What is the length of one side?

Answers

Since both shapes are the same,we divide the total perimeter by 2. 80÷2 is 40. Now that we have the perimeter of each individual shape we have to figure out the length of one side. Since all the sides are equal in length there is only 1 shape that has that - a square. A square has 4 sides so we need to divide 40 by 4 (because squares have 4 sides) and that equals to (40÷4) 10cm on each side. Hope I helped!
