Yes, they form a proportion. It would be 6/6 or 1.
Answer:
true.
Step-by-step explanation:
(x - y)z = xz - yz
Apply the distributive property of multiplication over addition to the left side:
(x - y)z =
= z(x - y)
= xz - yz
This is the same as the right side, so the statement is true.

Answer: Assuming the plumber will round up the hours, the answer is 335.
Step-by-step explanation:
You can use this equasion to solve the problem: 75+52x=c
In this case, x would equal the number of hours he would work and c would represent the final cost.
Basically, you can just multiply the hourly cost by the hours he works and then add the service fee. Hope this helped!
1047.84ft² is not covered by the pool.
Find the area of the yard covered by pull using the area of a circle formula (the height is irrelevant in this case). If the diameter of the pool is 24 feet, its radius is 12 (half of the diameter)
A = 3.14r^2
A =3.14(144)
A = 452.16 ft²
Subtract the area of the pool from the area of the yard to get the area of the yard that is not covered by the pool. If the dimensions of the yard are 30ft by 50ft, you multiply them to get the area: 1500ft²
Total yard area: 1,500ft²
Area of yard without pool: 1,500ft² - 452.16ft² = 1047.84ft²
