We can divide that up into two rectangles, say the bottom one 8 feet wide and 2 feet high. That leaves 5.5 by 6-2=4 feet for the other.
Cost = price × area = 2.25(8×2 + 5.5×4) = $85.50
Answer: $85.50
Answer: She will pay $52.68, including taxes
Step-by-step explanation: One can of tennis ball is $4 and there are no discount on it. Elena bought 3 cans, so:
can = 3 x 4 = 12
One tennis racket is $43 but it has a discount of 15%:
discount = 0.15 x 43 = 6.45
total racket = 43 - 6.45 = 36.55
Elena will have to pay:
pay = 12 + 36.55 = 48.55
She will also have to pay taxes, which are 8.5% over the price she paid:
pay + tax = 48.55 x 0.085 = 4.13
total to pay = 48.55 + 4.13 = 52.68
Buying 3 can of tennins ball and one racket, Elena paid $52.68, including taxes.
Let
be the amount of parts the student answered correctly. Suppose that
is a function between
and the score of a student's project. As the student initially receives a fixed
points for turning the project in and
points for each correct part, the function is initially:
When the students receive
points for each correct part, the coefficient of
changes, as the amount of points received per correct answer increases. Thus:
.
Step-by-step explanation:
7p²-30p+8
=(p-4)(7p-2)
Answer:
Step-by-step explanation:
systems of linear equations can only have 0, 1, or an infinite number of solutions. These two lines cannot intersect twice. The correct answer is that the system has one solution.
