Answer:
540
Step-by-step explanation:
sum of interior angles =(n-4)90
(10-4)90=
6×90=540
Answer:
Perimeter = (lenght×2) + (width×2)
Perimeter = (2.5n×2) + (2×(4n+5))
Perimeter = 5n + 8n + 10
Perimeter = 13n + 10
The Answer is D
The <em><u>correct answer</u></em> is:
C.4.1 in
Explanation:
We will use a proportion for this problem.
In the first ratio, we have 6 inches: 80 pounds. This can also be written as 6/80.
For the second ratio, we do not know the length; this is x. The weight is 55; this gives us x/55.
This makes our proportion
6/80 = x/55
Cross multiplying, we have
6(55) = 80(x)
330 = 80x
Divide both sides by 80:
330/80 = 80x/80
4.125 = x
This means the answer is 4.1.
Answer: The new boxes are 14 ft3 larger.
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of each box and compare them.
Volume of a rectangular prism = base x height x length
Replacing with the values given:
Old boxes volume: 4 x 2 x 2 =16 cubic feet
New boxes' volume: 3 x 5 x 2 = 30 cubic feet
Subtraction the old boxes volume to the new boxes volume:
30 ft3- 16 ft3 = 14 ft3
The new boxes are 14 ft3 larger.
