Answer:
1 cm
Step-by-step explanation:
We know that the formula for perimeter is<u> 2(l+w) or l+l+w+w</u>
We know that the height is 5 cm so that means <em><u>w= 5</u></em> also that there is 5 cm on both sides of the rectangle. So 5+5=10 so that means that the length of the rectangle is <em><u>1 cm</u></em> if you add the length together you 2 when you add the width you get 10. <em>10+2=12.</em>
This would be 12 - 12*cos(30) = 12 - 6
= 1.608 ft off the ground.
Answer:
$14
Step-by-step explanation:
x/17.5=20/100, do the butterfly method
17.5x20=350
350/100= 3.5
17.5-3.5=14
Answer: -101
Step-by-step explanation: f(n) = 19-6*n
f(20) = 19 - 6*20
f(20) = -101
The answer is 6.1 = 6 1/10
