Given:

Four lines are marked proportion, the length of TW can be determined by

$TW=a+4+b$

Value of a:

Let us set the proportion for the given lines.

Thus, we have;

$\frac{a}{7}=\frac{4}{5}$

$5a=28$

$a=5.6$

Thus, the value of a is 5.6

Value of b:

Let us set the proportion for the given lines.

Thus, we have;

$\frac{4}{5}=\frac{b}{5}$

$20=5b$

$4=b$

Thus, the value of b is 5.

Length of TW:

The length of TW is given by

$TW=5.6+4+4$

$TW=13.6$

Thus, the length of TW is 13.6

In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter

Sergeeva-Olga [200]

The answer is B.154/d = 44/14

In a circle, the circumference (C) and diameter (D) vary directly:
C = kD
k = C/D

Circle 1: k = C1/D1
Circle 2: k = C2/D2

C1/D1 = C2/D2
C1 = 154
D1 = ?
C2 = 44
D2 = 14

154/D1 = 44/14
So, the choice B. is correct.

Answer:

Find the smallest multiple the denominators have in common

Expand each fraction so that the denominators are 30

$\frac{8}{30} + \frac{- 5}{30}$

Add or subtract the numerators and keep the same denominator

$\frac{8- 5}{30}$

Simplify

$\frac{1}{10}$
