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:
$18
Step-by-step explanation:
since she saved 20% you turn the percentage into a decimal which is .20 then multiply it by 15 because that's how much she saved and you get $3 which you add to $15 and you get the regular price which is $18

Answer:
Step-by-step explanation:
so they get paid 175 in total for two days so 24 hours are in one day but we are looking for the hourly pay for two days so we use 48 as a dividing variable . so 175 divide by 48 is 3.65 so they get paid 3.65 per hour but if we have to round it out then 4 per hour
