Answer = 21/2 days or 10 and 1/2 days
It takes 14 electricians 18 days to wire a new housing subdivision.
One electrician take more time to wire a new housing subdivision.
So one electrician take 14 x 18 days to complete the job.
Therefore 24 electricians take less time to complete the job.
Number of days taken by 24 electricians to wire a new housing subdivision.= (14 x 18 )/24=21/2 days
Therefor 24 electricians take (14 x 18 )/24=21/2 days
Answer:
A = 30 inches^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2)h where b1 and b2 are the lengths of the bases
A = 1/2 ( 10+5) * 4
A = 1/2 (15)*4
A = 30 inches^2
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8
Answer:
1. A
2. B
3. D
Step-by-step explanation:
Use PEMDAS to solve all
1.
8^2 - 6*2
8*8 - 6*2
64 - 12 = 52
2.
4^2 * 3 + 4 * 2
4 * 4 * 3 + 4 * 2
16 * 3 + 8
48 + 8 = 56
3.
9^2 - 2(5+3)
9 * 9 - 2(8)
81 - 16 =65
Answer= (3 x b)+6
Because you multiply to find the total of the golf balls. Then you'll have to add 6.
