Step-by-step explanation:
Find negative square root of 16. (4 points) a −4 b 4 c ±4 d −8
The answer is B.
The total hours worked is 5 x 8 teams is 40 hours x 2 cars per hour is 80 cars.
$600/80= $7.50 per car
A couple are 5, 7, 17, 19, 23...
Answer:
73 mph
Step-by-step explanation:
The question seems to be incomplete because the model is missing, I found a similar question with the addition of the model, so if we can solve it (see attached image).
We have that the model would be:
y = 43.81 - 0.395 * x
We need to solve for x, if y = 15
Replacing:
15 = 43.81 - 0.395 * x
Solving for x we have:
0.395 * x = 43.81 - 15
0.395 * x = 28.81
x = 28.81 / 0.395
x = 72.9
We are asked to round to the nearest number therefore x = 73.
The car will average 15 miles per gallon at the speed of 73 miles per hour.
