Question does not say if the straight line is the least squares best fit line. Assuming it is, we still have the question whether Wilson's score vs hours spent per week is linear, as we do see some tendance of a decline of the rate of increase at the top of the the range, which means that the function COULD be parabolic or piecewise. The score could actually decrease if Wilson has difficulty doing the homework, to a point that he spent way over the expected time to finish relatively simple homework.
To sum up, the question is incomplete in supplying necessary information, perhaps on the part of the user posting the question, perhaps the school.
Anyway, back to the question, assuming a straight line relationship according to the given straight line, rate of increase per day = (50-15)/5=7 hours/week.
Therefore if Wilson spends 6 hours to do his homework, and assuming the score follows a straight line, he expects to get 50+7=57 points, an answer that is not one of the answer choices.
Perhaps the information is incomplete, perhaps there are other possible assumptions. That's the best we can do with the question as is.
Answer:
6 four-packs.
Step-by-step explanation:
My reasoning for 6 four-packs is that, the shopper needs 24, right? And if that shopper buys 6 four-packs it'll be cheaper than the larger package. The 6 four-packs come to a cost of $20.04. But the 4 six-packs will come out as $21.12. The shopper will be able to save $1.08 :)
Answer:
9.33 feet = 111.96 inches
Step-by-step explanation:
If we have similar triangles, the rate between matching sides is the same.
So the length of the smaller ladder (18 ft) over the length of the taller ladder (24 ft) is equal to the distance from the bottom of the smaller ladder to the tree (7 ft) over the distance from the bottom of the taller ladder to the tree (x ft):
18 / 7 = 24 / x
x = 7 * 24 / 18
x = 9.33 feet
To find this measure in inches, we just need to multiply by 12:
x = 9.33 * 12 = 111.96 inches
Answer:
(A)62.8 square feet
Step-by-step explanation:
Height of the barrels = 5 feet
Radius of the barrels= 2 feet
=3.14
The barrel is in the shape of a cylinder and the area of the label the company needs is that of the round sides(curved surface area) of the cylinder.
Curved Surface Area of a Cylinder=
=2X3.14X2X5
=62.8 square feet
The company need 62.8 square feet of label.
