Ms. Velez will use both x gray bricks and y red bricks to build a wall around her garden. Gray bricks cost $0.45 each and red br

Finger [1]

Let

x--------> the number of gray bricks

y--------> the number of red bricks

we know that

$y < \frac{x}{2}$ ------> inequality 1

$0.45x+0.58y \leq 200$ -----> inequality 2

therefore

the answer is

x > 0

0.45x+0.58y≤200

What is the measure of angle Q to the nearest whole degree? 43° 49° 53° 58°

geniusboy [140]

Answer:

m∠Q ≈ 53°

Step-by-step explanation:

To find the measure of ∠Q, the law of cosines will need to be used. Lowercase letters represent the side lengths, while upper case letters represent angles.

In this situation, 'A' will be ∠Q. Therefore:

17² = 18² + 20² -2(18)(20)cosQ

Simplify:

289 = 324 + 400 -2(360)cosQ

Continue simplifying down:

-435 = -720cosQ

Divide both sides by '-720':

0.604 = cosQ

$cos^{-1}Q = 0.604$

m∠Q ≈ 52.83 or 53° rounded to the nearest whole degree.
