Answers
Answer:
15.8 feet
Step-by-step explanation:
Stacy is making a shelf to store her books
She is using 5 pieces of wood
Each wood is 3.16 feet long
Therefore the total feet of the wood that Stacy will use to make the shelf cab me calculated as follows
= 3.16 ×5
= 15.8 feet

ok so the area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h. Add those two parts together and you have the formula for the surface area of a cylinder.
so To find the surface area, first multiply the length by the width to find the area. Since a cube is made up of six perfect squares, multiply the are aby six. That each measure four. Plug four into the formula to find the surface area
So the formula would be SA=2(LW+LH+WH
so area a^2+4=98^
So it is C
h
prism so 3 pairs of congruent sides thtat are oposite of each other
areas of each are
LW, WH, LH
(L=legnth,W=width,H=height and LW means L times W)
come in pairs
SA=2LW+2WH+2LH
undsitribue for ease
SA=2(LW+WH+LH)
L=4
W=3
H=5
sub
SA=2(4*3+3*5+4*5(
SA=2(12+15+20)
SA=2(47)
SA=94 cm^2
answer is C

Answer:
The plane from Seattle will pass the plane from Boston after 4.5 hours of its departure from the Seattle.
Step-by-step explanation:
Plane-1 = Boston, Massachusetts - Seattle, Washington at 10:00 AM
Plane-2= Seattle, Washington - Boston, Massachusetts at 11:00 AM
Speed of plane-1 = 300 mile/hour
Distance covered by plane-1 in 1 hour = 300 mile/h × 1 h = 300 mile
Distance between plane-1 and plane 2 after 1 hour :
= 3000 mile - 300 mile = 2700 mile
Let the distance covered by plane-1 after 1 hour be x in t time where it will pass plane-2.
Let the distance covered by plane-2 be y in t time where it will pass plane-1.
x + y = 2700 ...[1]
Speed of plane-1 = 300 mile/hour
..[2]
Speed of plane-2 = 300 mile/hour
..[3]
Putting value of t from [2] in [3];
x = y
In [1] put x = y
y + y = 2700 miles
2y = 2700 miles
y = 1,350 mile
For the value of t, put the value of y in [3]:
The plane from Seattle will pass the plane from Boston after 4.5 hours of its departure from the Seattle.
Final answer:
The Boston plane travels for 1 hour before the Seattle plane sets off, covering 300 miles. The remaining distance between them is then 2700 miles. Both planes flying towards each other at a combined speed of 600 mph cover this distance in 4.5 hours.
Explanation:
The subject of this question is a relative speed math problem. The Boston plane travels for an hour before the Seattle plane leaves. So, the Boston plane covers a distance of 300 miles (1 hour * 300 mph). This means that at the time the Seattle plane leaves, the total remaining distance between them is 2700 miles (3000 miles - 300 miles).
Now we consider both planes flying towards each other. In this case, the relative speed is the sum of their speeds, thus 600 mph (300 mph + 300 mph). So, to cover the remaining 2700 miles, it will take 4.5 hours (2700 miles ÷ 600 mph).
Therefore, the airplanes will meet each other 4.5 hours after the Seattle plane leaves.

Answer: the piece of wood is now 371.272 centimeters long. also please stop yelling.
Step-by-step explanation: To find the length of the piece of wood after 0.68 centimeters are sawed off, you need to subtract 0.68 from the original length of 371.952 centimeters.
371.952 - 0.68 = 371.272 centimeters
