81+86+89+96 equals an average of 88. If she wants an average of 90 she needs to score a 93 and 96 on the next two tests.
Answer:
2,4,8
Step-by-step explanation:
There are several important information's already given in the question. Based on those given information's the answer to the question can be easily deduced.
Total number of students in the school = 209
Ration of the boys to girls in the school = 6:5
Let us assume the common ratio to be = x
Then
6x + 5x = 209
11x = 209
x = 209/11
= 19
Then
The number of girls in the school = 19 * 5
= 95
So there are a total of 95 girls in the school that has a total of 209 students.

That depends on the position of the angle, if it's a central angle then the length of arc = 1/4 the circumference
so L = (1/4)(2pi(70))= 110 feet approximately

The answer is y2*2
