Answer:
$36.85
Step-by-step explanation:
23.95 and 35% discount
this means that $23.95 is 65% of the original value (100-35=65)
the highest common multiple of 35 and 65 is 5
so 65 divided by 5 is 13
23.95 divided by 13 is 1.8423...
then you take that number and times it by as many 5's are in 35 that would be 7
so the number times 7 is 12.89.....
now add this number to the original price and you have your answer $36.85
Answer:
The expression for the given value of the variable d=75 is, 135
Step-by-step explanation:
Given the expression:
![2d+\sqrt[3]{-45d}](https://tex.z-dn.net/?f=2d%2B%5Csqrt%5B3%5D%7B-45d%7D)
....[1]
We have to find the value for the given expression when d = 75
Substitute the value of d in [1] we have
![2(75)+\sqrt[3]{-45(75)}](https://tex.z-dn.net/?f=2%2875%29%2B%5Csqrt%5B3%5D%7B-45%2875%29%7D)
⇒ ![150+\sqrt[3]{-3375}](https://tex.z-dn.net/?f=150%2B%5Csqrt%5B3%5D%7B-3375%7D)
⇒
Simplify:
⇒
Therefore, the expression for the given value of the variable d=75 is, 135
Step-by-step explanation:
here I have done you can check it out
36/27=1.3
7x1.3=9.1
The actual length is 9.1meters
Write the coeeficientes of the polynomial in order:
| 1 - 5 6 - 30
|
|
|
------------------------
After some trials you probe with 5
| 1 - 5 6 - 30
|
|
5 | 5 0 30
-----------------------------
1 0 6 0 <---- residue
Given that the residue is 0, 5 is a root.
The quotient is x^2 + 6 = 0, which does not have a real root.
Therefore, 5 is the only root. You can prove it by solving the polynomial x^2 + 6 = 0.
