Answer:
Step-by-step explanation:
Given
Required
Determine x and WQP
From the attachment;
Substitute 152 for RQP, 31 + x for RQW, 139 + x for WQP
Collect Like Terms
Divide both sides by 2
To solve for RQW; substitute -9 for x in RQW = 31 + x
Answer:
b. 97
Step-by-step explanation:
Home work = 88
20 % of 88 = 88 x 20/100 = 17.60
Quiz Average= 84
25 % of 88 = 84 x 25/100 = 21
Test Average= 92
40 % of 92= 92 x 40/100 = 36.8
Add all = 17.60 +21+ 36.8= 75.40
Let the marks be x in final exam
The percentage is 15 % and scores a 90 in a class we can write
15x/100 + 75.40 =90
0.15x= 90-75.40
0.15x= 14.60
x= 14.60/0.15= 97
final exam marks will be 97

Step-by-step explanation:
Answer:
Arc length = 9.42 cm
Step-by-step explanation:
First you need the circumference of the circle
r = 6
C = 2* pi * r
C = 2 * 3.14 * 6 = 37.68
To find the length of the arc, we need to know the central angle. IN this case it is 90 degrees (notice the right angle of the triangle).
To find the length of the arc Arc length = (central angle in degrees/360) * C
Arc length = 90/360 * 37.68
Arc length = 9.42 cm
