Answer:

180 in

Step-by-step explanation:

The perimeter is just the sum of the lengths of the sides of the shape.

So all we need to do here is:

40+10+(40-18)+(50-10)+18+50.

I got (40-18) for the bottom of the top rectangle, the part that is poking out.

I got (50-10) for the right side of the rectangle that is poking out towards the bottom.

40+10+(40-18)+(50-10)+18+50

40+10+22       +40       +18+50

50     +62                      +68

50+62+68

112+68

180

180 in

I'm going to post a drawing here to show the lengths I was talking about:

Using the order of operations, what should be done first to evaluate mc019-1.jpg?
stellarik [79]

Answer:

"Multiply –6 and 3"


Step-by-step explanation:

For order of operations, we follow the rule PEMDAS

  • We do PARENTHESIS first, then
  • Exponents, then
  • Multiplication, then
  • Division, then
  • Addition, then
  • Subtraction

In this problem, we have parenthesis, so (-6)(3) should be done first.

Hence, we should multiply -6 and 3.

A square pyramid has a volume of 20 cubic feet and a base length of 5 feet. What is it's height?
erastova [34]

Answer:

The height of the pyramid is 2.4\ ft

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

V=\frac{1}{3}b^{2}h

we have

V=20\ ft^{3}

b=5\ ft

substitute and solve for h

20=\frac{1}{3}(5)^{2}h

60=(25)h

h=60/(25)=2.4\ ft
