It appears the question is asking you to make mathematical statements. Basically, just find a way to use the numbers above to make your own addition and subtraction problems. ADDITION 2.47 + 7.1 = 9.57 7.1 + 2.47 = 9.57 SUBTRACTION 9.57 - 7.1 = 2.47 9.57 - 2.47 = 7.1

Find the unit rate: 6 and 2/5 rotations in 2 and 2/3 seconds.
GrogVix [38]
I'd suggest you write "6 2/5," not "6 and 2/5."

6 2/5 rotations
-------------------- = 
2 2/3 seconds

32
---
 5            32       3
------- = ------ * -----
 8              5       8                 Reduce that 32/8:  obtain 4.
---
 3

Then we have

4(3)/5, or 12/5 rotations per sec.

Jim and bill each invest $15,000 into savings accounts that earn 3.5% interest. Jims account earns simple interests and bills ac
Svet_ta [14]

Answer:

Bill will earn more interest

He will earn $ 20,448.67 from his investment

Step-by-step explanation:

Firstly let us calculate Jim's earnings based on simple interest

A = P(1 + rt)

Calculation:

First, converting R percent to r

a decimal

r = R/100 = 3.5%/100 = 0.035 per year.

Solving our equation:

A = 15000(1 + (0.035 × 25)) = 28125

A = $28,125.00

The total amount accrued, principal plus interest, from simple interest on a principal of $15,000.00 at a rate of 3.5% per year for 25 years is $28,125.00 for Jim

Now let's us calculate bill's investment based on compound interest

Equation

A = P(1 + r)^t

A=15000(1+0.035)^25

A=15000(1.035)^25

A=15000*2.36324498427

A = $ 35,448.67

We see that Bill will earn

$ 20,448.67 from his investment
