Hello from MrBillDoesMath!
Answer:
72
Discussion:
Total Surface area = area of pyramid base + 4 ( area of triangular face)
In our case this becomes
4*4 + 4( (1/2) (4)(7) ) =
= 16 + (2)(4)(7)
= 16 + 56
= 72
which is the first choice.
Note: the area of a triangular face was computed using (1/2) b h, which in our case is
(1/2) (4) (7)
Thank you,
MrB

Answer:
C(m) = $(40+3m)
Step-by-step explanation:
In this question, we are asked to write an equation representing the total cost of renting a truck by Makayla.
We proceed as follows;
Form the question, we can deduce that there is an initial cost of $40 and a rental fee of $3 per mile driven.
Now, we were made to know that she had driven m miles. We now calculate the rental fee for this m miles she has driven. Mathematically, we only need to find the product here. The rental fees for the m Miles traveled would be m * 3 = $3m
Now the total cost C(m) would be = $40 + $3m or simply C(m) = $(40+3m)
I think it's true but I'm not 100% sure
Answer:
16.285
Step-by-step explanation:
you multiply a and b then divide by two cuz its a triangle
then you multiply b by pi and divide by 2 cuz its a semi circle
