Step-by-step explanation:
It appears to be just a slope problem in disguise. Where if you find the slope, you find the density of nickel. In this case, it would be copper. The slope appears to be closer to 9, and if you take some of the points and divide it, like where it seems to cross 4 and 35, you would get an answer close to 9. Same with 40 and 4.5, you get 8.89. The only answer closest to that would be H
Hello again! So we will be using the pythagorean theorem (
) to solve for the bottom leg of the triangles. After we do that, we'll subtract the value of the legs from 31, and that'll be x.
Plug in 17 and z (or any variable that isn't x) into the leg variable and 19 into the hypotenuse variable, and from there we can solve.
Solve the exponents to get
Subtract 289 on each side to get
Lastly, square root each side of the equation and your answer should be
(To get more accurate answers, you shouldn't round until the end of the problem)
Nextly, we will need to subtract
from 31. And since there are 2 triangles, you'll need to multiply
by 2.
In short, x = 14.0
Step-by-step explanation:
Given that,
Maggie bought c CDs for $12 each, b books for $7 each, and a purse costing $24.
(a) Cost of c CDs = 12c
Cost of b books = 7b
Cost of p purse = 24p
Total amount = 12c+7b+24p
(b) Cost of 4 CDs = 12(4) = $48
Cost of 3 books = 7(3) = $21
Hence, this is the required solution.
Answer:
Yes!
