Answer:  b = 10

Step-by-step explanation:

We want a ratio of b/2 that is equal to the ratio of 1/4 to 1 1/4 (or 5/4).

Ratio of (1/4)/(5/4):

(1/4)/(5/4) = (1/4)*(4/5) = 4/20 = 1/5 or 0.2

We want 2/b = 1/5 or 0.20

2/b = 0.20

b = 2/0.20

b = 10

--

Check:  Does 10/2 = (1/4)/(5/4)?

Yes

b is 10

Trava [24]

Answer:

C). Circle Graph

Step-by-step explanation:

As per the question, a '<u>circle graph</u>' would be most adequate to display that the majority of the teenagers prefer to do their study and homework in their bedrooms. <u>A circle graph or pie-chart represents the data in a visually appealing manner using colors to display various proportions of the data that makes it easy to understand for the readers</u>. Thus, <u>more than half of the circle filled with the same color will clearly hint that most of the teenagers love doing their studies in their bedroom</u>. Thus, <u>option C</u> is the correct answer.

The monthly cost of a short term disability insurance policy varies directly as the salary of the employee. Wanda has an annual
arlik [135]

Answer: $14.85

Step-by-step explanation:

Ww can solve the question using direct proportion with the formula y = kx

where y = annual salary

x = monthly policy cost.

k = constant of proportionality

Since y = kx

38500 = 11.55k

k = 38500 / 11.55

k = $3333.33

When Randy has an annual salary of $49,500, the amount Randy expect to pay for his policy will be:

y = kx

49500 = 3333.33x

x = 49500 / 3333.33

x = 14.85

The amount that Randy expect to pay for his policy will be $14.85
