Answer:
; 
Step-by-step explanation:
Score of the first two quizzes: 75 and 97
Let n represent the third score
Average score would be: 
.
Given that the average score fall between 85 and 90, this can be represented by the compound inequality as shown below:
Solve for n in each statement that makes up the compound inequality:
Multiply both sides by 3
Subtract 172 from each side of the inequality
Also,
Multiply both sides by 3
Subtract 172 from both sides of the inequality
Combining both together, the possible values of her third quiz score would be:
Answer:
(3, 6)
Step-by-step explanation:
If you create a mini graph, like I did, you would have seen that the middle point is at the co-ordinates (3,6). I have attached a image to this reply, with my "graph". (Sorry if its a little ugly, but that doesn't matter, the math does.)
Answer:
Rs. 112000
Step-by-step explanation:
- Borrowed money = Rs. 126000
- Interest rate = 15% PA simple
- Time = 3 years
<u>Hari is due to pay after 3 years:</u>

He pays Rs. 70700, remaining money is cleared by giving buffalo.
<u>Cost of buffalo:</u>
- 182700 - 70700= Rs. 112000
<u>Answer is:</u> Rs. 112000
Answer:
252m^3
Step-by-step explanation:
A solid having a triangular base is what we call a triangular prism. For every prism, its volume is always equal to the area of its base times its height. In other words:
V = AxH
V - volume
A- area
H - height of prism
We know that:
h = 4 m (side of base)
b = 14 (other base side)
A = bh/2 = 14x4/2 = 28 m^2
And then: V = A x H = 28 x 9 = 252 m^3
