Answer: C
Step-by-step explanation:
The surface area of a pyramid = A + 1/2ps
Where A = area of the base
P = perimeter of base
S = slant height.
A = 4 × 4 = 16 m^2
P = 4L = 4 × 4 = 16 m
S = 3m
Surface area = 16 + 1/2 × 16 × 3
Surface area = 16 + 24
Pyramid surface area = 40 m^2
The surface area of the cuboid = LB + 2LH + 2BH
Where
B = width
H = height
L = length
Substitute all the parameters into the formula
Surface area = 4×4 + 2(4×5) + 2(4×5)
Surface area = 16 + 40 + 40
Surface area = 96 m^2
To Find the surface area of this composite solid, you will add the pyramid surface area to the cuboid surface area. That is
Total surface area = 40 + 96 = 136m^2
Therefore, the surface area of this composite solid is 136 cubic meters
Answer:
14 gel pens/minute
Step-by-step explanation:
divide the amount by time.
210/15 = 14
The answer is B because if the result is 3/4 and the question is asking to the result then you would an equation.
Set up and solve an equation of ratios. Comparing shadow lengths, we get 100/6; comparing heights, we get x/8. Set these two ratios equal to one another and solve the resulting equation for x:
100 x
----- = ------ Then 6x=800, and x = 800 feet^2 over 6 feet. Your answer
6 8
must have the unit of measurement "ft."
Step-by-step explanation:
these are multiplications.
you could also write
4 + 5×(p - 1)
now, we need to calculate the contents of brackets (if we can), then do the multiplications and divisions, before we can do the then remaining additions and subtractions.
if we cannot do a calculation directly (because there is a variable involved), we need to do and document the single steps for the individual parts involved.
so,
4 + 5×(p - 1) = 4 + 5×p + 5×-1 = 4 + 5p - 5 = 5p - 1
remember, a multiplication of 2 expressions is done by multiplying every term of one expression with every term of the other expression and adding the results up (by considering their individual signs, of course).
