Answer:

a. h = 700

b. j = 6400

c. g = 50

Step-by-step explanation:

Translate each statement into an equation and solve the equation. Remember that to change a percent to a decimal, you divide the percent by 100, which is the same as moving the decimal point two places to the left. Also, a percent of a number means a percent times the number.

a. 20% of h is 140

20% * h = 140

0.2h = 140

Divide both sides by 0.2

h = 700

b. 5% of j is 320

5% * j = 320

0.05j = 320

Divide both sides by 0.05

j = 6400

c. 30% of g is 15

30% * g = 15

0.3g = 15

Divide both sides by 0.3

g = 50

Answer:

50 minutes

Step-by-step explanation:

she spent 1 hr and 30 minutes on homework

she spends 2/3 of an hour on the phone = 40 minutes

1 hr 30 min + 40 minutes = 2 hrs and 10 min

so she had 50 minutes to kill before bedtime since she goes to sleep 3 hrs after dinner

2hr 10 min + 50 min = 3 hrs.

Find the missing dimension use the scale factor 1:12 model 32 cm find the actual in m
gizmo_the_mogwai [7]

Given:

The scale factor is 1:12.

Dimension of model = 32 cm

To find:

The actual dimension in m.

Solution:

Let x be the actual dimension.

The scale factor is 1:12 and the dimension of model is 32 cm.

\dfrac{1}{12}=\dfrac{32}{x}

On cross multiplication, we get

x=32\times 12

x=384\ cm

x=3.84\ m             [\because 1\ m=100\ cm]

Therefore, the actual dimension is 3.84 m.
