The whole wall area including the window is 150 ft squared (15 ft x 10 ft). The window is 50 square feet (5 x 10). Take the whole area and subtract the window area and you have 100 sq ft thats paintable. One can is 50 sq ft so 100/50 is 2 cans of paint needed. Your answer is H.
Answer:
Question 13: x = 47°
Question 14: x = 67°
Step-by-step explanation:
Question 13:
add up all the known factors meaning 16, 27 and 90°, then subtract 180 from what you got from adding known factors
Question 14:
out out of all numbers meaning 19, 4 and 90°, then subtract 180 from what you got from adding all known factors
The 3rd one
You can factor 3 out of each term in the numerator. And then divide it by the 3 in the denominator.
the equations
1/4=2x and 1/4/x=2have the same solution
because 1 / 4/ x = 2 can be simplified to
1 / 4 = 2x which is the same with the first equation
Solve for x = 1/8
Then substitute it to the both equation
¼ = 2 ( ¼)
¼ = ¼
2nd equation
1/ 4 /( 1/8) = 2
2 =2
