Answer:
13/90 > 1/7 or 1/7 < 7/90
Step-by-step explanation:
to compare two rational expression you should make the denominator equal
1/7 ➡ ×90 = 90/630
13/90 ➡ ×7 = 91/630
For this case we can use the Pythagorean theorem to solve the problem.
We have then for the following complex number:

Using the Pythagorean theorem:

Rewriting we have:
Answer:
A complex number that has an absolute value of 5 is:
A)–3 + 4i
To solve this problem you must apply the proccedure shown below:
1. You have that the following information given in the problem above: The<span> photograph is reduced by a scale factor of 3/8 and the original had a length of 20 inches,
2- Therefore you have:
length=20 inches-</span>(20 inches x 3/8)<span>
length=20 inches-7.5 inches
length=12.5 inches
3- Then, as you can see, the answer is: 12.5 inches.</span>
Step-by-step explanation:
Louise calculated the height of a cylinder that has a volume of 486 pi cubic centimetres and a radius of 9 centimetres.
The formula for the volume of cylinder is :
V = B × h
B is area of base of cylinder

i.e.

Substituting given values,

will cancel out from both sides.

She forgets to cancel down
from both sides. So, she get height as
. So, in the
should have canceled, making the correct answer 6 cm.
