Answer: 6 hours
Step-by-step explanation:
Taylor cannot spend over $260.
Subtract the cost of the part needed for the repair:
= 260 - 80
= $180
$180 is left for fixing the car after buying the part.
As the labor costs $30 and now she cannot exceed $180 for labor, the total number of hours the mechanic can work is:
= 180 / 30
= 6 hours
Answer:
Step-by-step explanation:
Answer:
(x-1)²+(y-3.5)² = 265/4
Step-by-step explanation:
first find the midpoint (center of the circle)
(9+-7)/2, (2+5)/2
(1, 3.5) = center
then distance formula to find diameter
√(9- -7)²+(2-5)²=√256+9 = √265
The radius is half the diameter = (√265)/2
Formula for circle is (x-h)²+(y-k)²=r², where (h, k) is the center
Now you can plug everything in.
(x-1)²+(y-3.5)² = 265/4
The founded number should be 9,000
If you would like to know how long will it take to drain the pool, you can calculate this using the following steps:
3 hours ... 250 gallons
x hours = ? ... 150 gallons (= 400 - 250)
3 * 150 = 250 * x
x = 3 * 150 / 250
x = 1.8 hours
3 hours + 1.8 hours = 4.8 hours
The correct result would be B. 4.8 hours.
16/6.72 = 2.38... ounces per dollar
10/4.5 = 2.222... ounces per dollar
The 16 ounce deal is better, as you get more ounces per dollar
