Answer:
1: -13
Step-by-step explanation:
First, simplify the equation to -2y+10=36
Subtract 10 from both sides
-2y=26
Divide negative 2 from both sides
y=-13
Garden
max area is if the sides are as equal as possible
so he should try to make a square (ideal is a circle, but barn walls are normally straight)
squaer perimiter=4 times legnth of 1 side
perimiter=amount of fencing=80
80=4s
divide 4
20=s
one sides=20
area=legnth times width
in squaer, legnth=width
20=legnth
20=width
area=20 times 20=400
dimetions are 20ft by 20ft to give 400ft^2
(fun fact, if it were a circle, the area would be about 509.5ft^2)
answer is 20ft by 20ft and area=400ft^2
The formula for the area of a triangle is half the base times the height. So 1/2 x 40 x 32 = 640cm^2
Answer:
4,784
Step-by-step explanation:
Find how many are defective
Convert 8% to a decimal
8/100=0.08
Multiply
5,200*0.08=416
416 are defective, to find how many aren't subtract the defective from the whole
5,200-416=4784
So, 4,784 are not defective
Hope this helps! :)
