Answer:
Step-by-step explanation:
- Initial number = 470
- Decrease rate = 12% ⇒ 100% - 12% = 88% ⇒ 0.88 times
<u>Required equation:</u>
Correct choice is C
Answer:
4
Step-by-step explanation:
1/3 x 12= 4
Answer:
The value of x is 3.
Step-by-step explanation:
Consider the below figure attached with this question.
Given: Quadrilateral QUAD is a rectangle, DU=26 and QP=2x+7.
We need to find the value of x.
Diagonals of a rectangle are equal.
.... (1)
Diagonals bisect each other.
.... (2)
Using (1) and (2) we get
Substitute given values.
Divide both sides by 3.
Hence, the value of x is 3.
Answer:
d= 90 degrees
e= 99 degrees
f= 81 degrees
Step-by-step explanation:
To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees
