We need to first find the area of all the dozen planks, top and bottom.
A=(length)(width)
A=(8)(3)=24 feet squared
24+24=48 feet squared for each plank
Then, you would multiply 48 with 12 since all the planks have the same dimensions.
(48)(12)=576 feet squared in total
Then in order to find the number of pints of varnish needed to cover the dozen planks top and bottom, we need to divide the total area, 576 with 125 which is about 4.608 which means that Alex needs 5 pints of varnish to cover all the planks.
Answer: 4 pints of varnish
The vertex form of 4x^2+16x-1 is
4(x+2)^2 - 17
The answer to your question is
24
Answer:
B.
Step-by-step explanation:
Since the main goal for Marco is to stay under his budget which is 279, it's expected that he would want to spend less than or equal to his budget and that is the point to spend less than our goal of spending limit. If the cost of uniform and the cost of each of his classes are less than how much money he wants to spend, than that is going to still be within his budget even if the equation equals to 279 it is still within his budget anything greater would be consider over spending past his budget. Therefore making all other equations false.
So the total cost (C) would be equal to the standard charge (S) plus the insurance charge (I). You would plug in the numbers for each into an equation C= S + I.
Unfortunately, I do not understand the numbers given in the equation. There should be a variable for m (the number of miles driven). Although there is an m in the question, the numbers in front of it for the standard charge or insurance do not make sense to me. =I+5.700.25M and
=S+18.950.40M.
Example:
If I was 5.7 + 25m and S was 18.95 + 40m, the equation would look like:
C= S + I
C= 18.95 + 40m + 5.7 + 25m
C= 65m + 24.95
Thanks for asking for my help! Sorry I could not be of more help for you!! :(
