We will use reciprocal over here which means the question will now be
8/-4 x 9/-3
The answer will be 6
Answer:
EY = 60
DW = 68
DE = 128
Step-by-step explanation:
Given
As YW is the perpendicular bisector of EF, then EY = FY
FY = √(FW² - YW²) = √(68² - 32²) = 60
⇒ EY = 60
As WX is the perpendicular bisector of DF, then DW = FW
As FW = 68, then DW = 68
As WZ is the perpendicular bisector of DE, then DZ = EZ = 64
Therefore, DE = DZ + EZ = 64 + 64 = 128
Solution:
<u>It should be noted:</u>
<u>Using the formula:</u>
- Slope = Rise/Run
- => Rise = 1; Run = 2
- => Slope = 1/2
Correct option is A.
First of all, you need to get them all in the same format, easiest is decimal.
red = 1.25
yellow= 1.40
green = 1.20
blue = 1.50
so the order is blue, yellow, red, and lastly green
We find the average by adding up all the students and dividing them by the number of classes she has. 19 + 13 + 19 + 9 + 14 + 15 is 89, and that divided by 6 is approximately 14.8, rounded to the nearest tenth.
