Answer:

a = 53

Step-by-step explanation:

A bisector creates two equal angles. Set them equal to each other.

5a - 160 = 2a - 1 ( subtract 2a from both sides)

3a = 159 (add 159 to both sides)

a = 53 (divide by 3)

Question:

Hector has a floor plan showing his new house. On the floor plan, his bedroom is 3 inches wide and 3 1/2 inches long. The scale of the floor plan is 1/4 inch = 1 foot. What is the actual length of Hector’s room?

Answer:

The actual length of Hector room is 14 foot

Solution:

Given that, On the floor plan, his bedroom is 3 inches wide and $3\frac{1}{2}$ inches long

The scale of floor plan is given as:

$\frac{1}{4} \text{ inch} = 1 \text{ foot }$

Therefore,

$1 \text{ inch } = 4 \text{ foot}$

To find: Actual length of floor

From given question,

$length = 3\frac{1}{2} \text{ inches}$

Converting the mixed fraction to improper fraction,

$length = \frac{2 \times 3 + 1}{2} = \frac{7}{2} \text{ inches }$

Since, 1 inch = 4 foot

$\frac{7}{2} \text{ inches } = \frac{7}{2} \times 4 \text{ foot } = 14 \text{ foot }$

Thus actual length of Hector room is 14 foot

alekssr [168]

The answer would be A!

Whenever there is a fraction in the exponent, the numerator is under the square root, and the denominator is on the outside of the square root!

Additionally, since the negative is outside of the square toot, then it also outside of the parenthesis.
