90 hours. If you divide the total number of gallons (6750) by the rate of 75 gal/hour, it will take 90 hours to fill the whole pool.
Answer:
42*
Step-by-step explanation:
Each triangle's angles in sum give 180 degrees. From here we add 68 and 70 to get 138, then subtract 138 from 180 to get 42, and that would be the third angle.
Tell me if I'm wrong :)
Answer:
b = 40
Step-by-step explanation:
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair.
This situation can be described by an equation of the form y=mx+b , where
x = the time in hours
y = the cost in dollars.
What is the value of b in this equation?
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair
Writing the above in an equation =
y = $70 × x + $40
y = 70x + 40
Therefore, the value of b in the expression = 40
X^2 - 7x + 10 =
(x - 5)(x - 2) <==
Answer:
a) (4,5)
b) (0,-3)
Step-by-step explanation:
We have to perform the following reflection over given ordered pair.
a) Reflect the ordered pair (-4,5) across the y-axis
Reflection over y-axis:
Thus, (-4,5) will be reflected over y-axis as
b) Reflect the ordered pair (0,3) across the y-axis
Reflection over x-axis:
Thus, (0,3) will be reflected over x-axis as
