Answer:
a
Step-by-step explanation:
math
c is right answer because 54.15 is bigger than 54.05
7) So when x=6 then z=72, they are directly proportional, so if I multiply the first with a number, then I have to multiply the second with the same number.
6 becomes 13 (x) /multiplied with about 2.167/
72 becomes 156(y) /multiplied with about 2.167/
8) Inversely proportional, so if I multiply the first with a number, then I have to divide the second with the same number.
6 becomes 13 (x)
2 becomes ~0.92307(y) /round it to the thousandths place and you get 0.923/
28 is not a cube, and 63 is not a square. The simplest form is the form you have.
![\sqrt[3]{28}-\sqrt{63}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B28%7D-%5Csqrt%7B63%7D)
Answer:
13 1/3 pounds.
Step-by-step explanation:
3 feet = 36 inches
3 feet 4 inches = 36 + 4 = 40 inches
By proportion the weight of the larger bar = 12 * 40/36
= 12 * 10/9
= 120/9
= 13 1/3 pounds.
