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

You should write down and track only the 20lbs weight during your weighted exercise while ignoring your body weight.

<h3>What is actual weight?</h3>

Actual weight is also referred to as gross weight and it can be defined as the exact (original) weight of an object, as measured using an appropriate weighing scale.

This ultimately implies that, you would write down and track only the 20lbs weight during your weighted exercise such as a single rep of weighted overhand chin ups.

Given two dice, what is the probability of rolling a four on the second die, given that you already rolled a four on the first d
Sholpan [36]

Answer:   1/6

Reason:

There's 1 side labeled "4" out of 6 sides total. So that's where the 1/6 comes from.

The "given that you already rolled a four on the first die" is unneeded info in my opinion, because each die is separate or independent from one another.
