5 · (7 - 4)² : 3 + 11 = 5 · 3² : 3 + 11 = 5 · 9 : 3 + 11 = 45 : 3 + 11= 15 + 11 = 26


5 · (7 - 4) · 2 : 3 + 11 = 5 · 3 · 2 : 3 + 11 = 15 · 2 : 3 + 11 = 30 : 3 + 11 = 10 + 11 = 21

Stephan con run 3 miles in 15.75 minutes. Keisha con run 5 miles in 22.6 minutes. Who can run faster?​
Marina CMI [18]

Answer: Keisha can run faster than Stephan.

Step-by-step explanation:

Let's figure out how long it takes for them to run a mile.

\frac{15.75}{3} =5.25\\\frac{3}{3} = 1

It would take Stephan 5.25 minutes to run a mile

\frac{22.6}{5} =4.52\\\\\frac{5}{5} =1

It would take Keisha 4.52 minutes to run a mile

Since Keisha takes less time to run a mile she is faster.

Naomi deposited money into savings account that is compunded quarterly at an interest rate of 6%. She thinks this quarterly rate
FromTheMoon [43]

Answer:

No, because 1.25% times 3 is 3.75% which is less than 6%

Step-by-step explanation:

Quarterly is every 3 months

6% interest is 1.06, 6 cents on the dollar

Monthly interest rate is 1.25% so 1.25 × 3 is 3.75

So, 1.25% times 3 is 3.75% which is 2.25% less than 6%

Hope this helps!

Have a great day!

lutik1710 [3]

Answer:

3. 60 ÷ 5 = 12

12 × 3 = 36

7 3/5 hours = 7 hours and 36 minutes

7:36 - 30 = 7:06

7:06 - 42 = 6:24

6:24 ÷ 6 = 1:04

A. 1 1/15 hours

4. fractions are equivalent regardless of the negative sign placement

A. 4/-9 = -4/9

5. 3/2 = 12

4/2 = 16

12 × 16 = 192

C. 192 square feet

7. -2.9a + 6.8 + 4.4a - 7.3 (add -2.9a + 4.4a)

1.5a + 6.8 - 7.3 (subtract 6.8 - 7.3)

1.5a - 0.5

D. 1.5a - 0.5

8. 552.50 × 0.88 = 486.2

486.2 ÷ 7 = 69.457

B. m > 69.45

19. -1/6 + 2/3(9 - 3/4) - 1/2

2/3 × 9/1 = 18/3

2/3 × 3/4 = 6/12

-1/6 + 18/3 - 6/12 - 1/2

-1/6 + 36/6 - 6/12 - 1/2

35/6 - 6/12 - 1/2

70/12 - 6/12 - 1/2

64/12 - 1/2

64/12 - 6/12
