Set the formula up and insert the stuff
=16.56 if you use the A=PIr^2
Step-by-step explanation:
Since the ratio of monthly income to savings of the family is 7:2, we assume that the income be 7t and savings be 2t
Now, we are given that the savings is =Rs 500
So, According to our assumption, 2t=500
⇒t=250
Hence, the income of the family is =7×250=Rs 1750
And the expenditure is =Income−Savings
=Rs 1750−Rs 500
=Rs 1250
Q14) 8 times 1/2=4
Q15) 3/4>1/2 (1/2 =2/4)
Q16) 1/8, 3/8, 5/8
Answer:
see attached
Step-by-step explanation:
The first application of the Pythagorean theorem is used to find the diagonal of one face. That is called 'a' in this problem. Then the second application of the Pythagorean theorem uses that value of 'a' along with the remaining prism dimension to find the space diagonal 'c'.
__
You don't actually have to find 'a', because you only need the value of a². Using the first equation to substitute into the second equation gives ...
6² +8² +12² = c²
Answer: 2 1/4
Step-by-step Explanation: First change 18 to 17 4/4. Now subtract. 17-15=2, 4/4- 3/4 = 1/4. Now combine them to get, 2 1/4
