Answer: The height of wall is 10.5 feet.
Step-by-step explanation:
Since we have given that
Number of bricks to build = 1470
Length of wall = 20 feet
We need to find the height of wall.
As we know that
Bricklayer's formula is given by

Hence, the height of wall is 10.5 feet.

Answer:
Step-by-step explanation:
We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:
C = 3.1415(1.5) so
C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.
