For question 2, the answer is 120 cm^2
The formula is SA = b + 1/2 ps
p = perimeter
s = slant height
this is a square, so all the sides are equal. So 6 cm x 4 = 24 cm, this is the perimeter of the base.
then multiply this by the slant height, and you get 192.
192 x 1/2 = 96.
96 + 24 (the area of the base) = 120.
120 = 24 + (1/2 x 24 x 8)
Answer:
T
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
The formula would be c=(320/x)+3
C is the total chairs and x is the price per chair and we add 3 since she is getting 3 for free
Following PEMDAS, we should do 320/80 first which is 4
Then the equation becomes 4+3=7
