Answer:
Step-by-step explanation:
Find the area of each shape, then multiply by 20, then round to nearest hundred.
Half circle:
=πr²/2
=50π
=157.08
Large square:
=L•w
=20(22)
=440
Small square:
=L(w)
=12(3)
=36
Triangle:
=b(h)/2
=8(3)/2
=12
Btu req:
=(157.08+440+36+12)(20)
=(645.08)(20)
=12901.6
=12900 BTU
Answer:
Try 116?
Explanation:
First, let's us know the formula for finding area of a rectangle.
Formula - A = l * w
In the image, it shows the length (12) and width (10)
Length = L
Width = W
Now, what is 12 x 10? 120
Because we need the shaded region and the little box isn't apart of it, we need to find the area of that box to and subtract it from big box
The length is 2 and the width is 2, shown by the image.
2x2 = 4
120-4 = 116
This problem involves the dot product.
You must provide all info for position vector m. Your (2,) is inadequate.
Supposing that the terminal point of vector m were (2,3), then
m dot n would equal 8, or 8 = 2*2+3*y. Then 8 = 4 + 3y, and 4 = 3y, and y =3/4.
Please type in the terminal point of vector m and then answer this question following the above example.
$2.00. $12 divided by 6(bars) makes each bar $2.00 dollars, with Sophia $20.00 divided by 10(bars) makes each 2 bar $2.00 so $2.00 is the answer
