In ΔPQR, r = 9 inches, p = 6.6 inches and ∠Q=6°. Find the area of ΔPQR, to the nearest 10th of a square inch
Andreyy89

Answer:

2.8 square inches

Step-by-step explanation:

Area of the triangle PQR = 1/2 rp sin <Q

Given

r = 9in

p = 6.6in

<Q =6°

Substitute into the formula;

Area of the triangle PQR = 1/2 * 9 * 6 sin6°

Area of the triangle PQR = 9 * 3 sin6°

Area of the triangle PQR  = 27 sin6°

Area of the triangle PQR = 27(0.1045)

Area of the triangle PQR = 2.82

Hence the area to the nearest 10th of a square inch is 2.8 square inches

A red candle is 8 inches tall and burns at a rate of 7/10 inch per hour.
WITCHER [35]

Answer:

4 Hours

Step-by-step explanation:

we will set up two linear equations first by taking the initial height if each candle and subtracting the rate they burn at times our input variable of time (x) equal to height (y)

So, 8-7/10x=y and 6-1/5x=y

then, because both equations equal y you can set them equal to each other so

8-7/10x=6-1/5x

Finally, solve for x

8-7/10x=6-1/5x

subtract 6 from both sides

2-7/10x=-1/5x

add 7/10 x to both sides (1/5x=2/10x)

2=5/10x

simplify

2=1/2x

x=4

Oceanside bike rental shop charges 16 dollars plus 9 dollars an hour for renting a bike.Sam paid 52 dollars to rent a bike.How m
lara31 [8.8K]

Answer:

4 Hours

Step-by-step explanation:

Since the equation is:

y = 9x + 16

You have to find x

This is the logical way:

52-16 = 36 because thats the starting fee

So 36 divided by 9 equals 4

You do that because 9 is the charge per hr

So he rented it for 4 hours.

Hope this helps:)
