The answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.

An angle measures 18.6° less than the measure of its complementary angle. What is the measure of each angle?
weeeeeb [17]

Answer:

X = 35.7 Y=54.3

Step-by-step explanation:

Let the 2 angles be called X and Y were X is the smaller angle

we know that both angles are complementary therefore
X+Y=90

X = Y - 18.6 ( Given )

Y - 18.6 + Y = 90 ( substitution)

2Y = 90 + 18.6

Y = 108.6/2

Y=54.3

X= Y-18.6= 54.3-18.6 = 35.7

Check : X + Y = 35.7+54.3=90

Tell whether the exact answer is reasonable 2.411. Mr. Jones sells gaones sells gardening supplies. A shovel sells for $19.He sa
dezoksy [38]
If he is selling shovels at $19 each, the answer of $153 would be incorrect. If you take $153 and divide that by 8 (shovels) you will get each shovel being a price of $19.125 each. 
The overall answer of $153 could be reasonable but the overall price from selling 8 shovels will actually be $154 not $153.
