Look here in a square which is what I imagine that drawing is all the angles are 90 degrees. A rectangle would be knowing two angles is know all of them one way or another so fix your work and you should know the answer
1/4 dividend by 5/13 is the same as
1/4 multiplied by 13/5 it’s inverse
1 x13 / 4x 5 = 13/20
Answer:
The formula: e7 = (b7*d7)+(c7*d7*1.5)
Step-by-step explanation:
Given:
Hours worked = b7
Hourly rate = d7
Overtime hours = c7
Salary calculation = e7
Salary = Hours worked*hourly rate + (overtime*hourly rate)*1.5
Formula
e7 = (b7*d7)+(c7*d7*1.5)
The formula e7 = (b7*d7)+(c7*d7*1.5)
Hope this will helpful to you.
Thank you.
Answer:

Step-by-step explanation:
We want to simplify:

We rewrite the expression under the radical sign to obtain:

We split the expression under the radical sign to get:

Recall that:

This implies that:

Therefore 
SOLUTION:
Let whole number = x
x + 2x^2 = 21
2x^2 + x - 21 = 0
2x^2 + 7x - 6x - 21 = 0
x ( 2x + 7 ) - 3 ( 2x + 7 ) = 0
( 2x + 7 ) ( x - 3 ) = 0
2x + 7 = 0
2x = - 7
x = - 7 / 2
OR
x - 3 = 0
x = 3
ANSWER:
Therefore, as 3 is a whole number while - 7 / 2 isn't a whole number, the whole number must be 3.
Hope this helps! :)
