Answer:
Semicircle = 
semicircle = 
semicircle = 51.4
∴ the perimeter is 14 + 32 + 51.4
∴ The perimeter is 97.4 cm
Area 1 = 
Area 1 = 20 ÷ 2 = 10
Area 1 = 
Area 1 = 314.2
Area 2 = 14 × 32 = 448
Area = Area 1 + Area 2
Area = 762.2cm²
Step-by-step explanation:
1) we calculate the volume of the first carton:
volume=length x width x height
volume=3 ft * 2 ft * 2 ft=12 ft³
Therefore:
A machine can fill 12 ft³ in 3 seconds.
2) we calculate the volume of the second carton.
volume=length x width x heigth
volume=4 ft * 5 ft * 6 ft=120 ft³
3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.
12 ft³---------------------3 seconds
120 ft³-------------------- x
x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.
answer: 30 seconds.
I believe all you would have to do to change it from a negative to a positive exponent is:
Put a 1 as the numerator (on top of the fraction). Then, put 3⁵ on the bottom as the denominator.
There's your answer! 1 / 3⁵
Answer:
y= -x-8
Step-by-step explanation:
The ones in the equation are in subscript, couldn't get the equation creator to work properly....DO NOT multiply by one, they are merely subscript meant to help you identify which pair to use.
y-y1=m(x-x1)
-5=x1
-3=y1
-1=m
y- -3=-1(x- -5) then you arrive at y+3=-1(x+5)
y+3=-x-5 now you isolate the y on the left y=-x-8
