Answer:
149.45 cm²
Step-by-step explanation:
Surface area of pyramid = ½Pl + BA
Perimeter of the base (P) = 7 + 7 + 7 = 21 cm
Slant height (l) = 12.2 cm
Area of base (BA) = ½*bh = ½*7*6.1 = 21.35 cm²
Plug in the values
Surface area = ½*21*12.2 + 21.35 = 149.45 cm²
Answer:
n = 25
Step-by-step explanation:
-2n + 15 = n - 60
Subtract 15 to both sides
-2n = n - 75
Subtract n to both sides
-3n = -75
Divide -3 to both sides
n = 25
Best of Luck!

Answer:
Jamal hiked = 44/3 miles
Step-by-step explanation:
Mixed numbers are given in this question which can be changed into fractions by multiplying the denominator by quotient and adding numerator to it.
Given that:
Length of first trail: 5 1/3 = (3*5 + 1)/3 = 16/3 miles
According to given condition:
Length of second trail: 1 3/4 * 16/3 = (4*1+3)/4 * 16/3 = 7/4*16/3
By simplifying:
Length of second trail = 28/3 miles
So the total miles Jamal hiked = 16/3 + 28/3
Jamal hiked = 44/3 miles
i hope it will help you!
