Answer:
The number of boys is 34 And The number of girls is 16
Step-by-step explanation:
Given as :
Total number of boys and girls = 50
Total amount to be divided between boys and girls = Rs 41
The amount given to each boys = 90 paise = Rs 0.9
The amount given to each girls = 65 paise = Rs 0.65
Let The number of Boys = B
The numbers of girls = G
So, According to question
0.9 B + 0.65 G = Rs 41
And B + G = 50
Or, 0.9 B + 0.65 G = Rs 41 .......1
And 0.9 B + 0.9 G = 45 ......2
Now, ( 0.9 B + 0.9 G ) - ( 0.9 B + 0.65 G ) = 45 - 41
Or, 0.25 G = 4
∴ G = = 16
And The number of boys = B = 50 - G = 50 - 16 = 34
Hence The number of boys is 34 And The number of girls is 16 Answer
Answer: Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3 =45 hours.
Step-by-step explanation:
Given : Duration of Tina practiced piano last month= 15 hours
Duration of Tina practiced piano this month= 45 hours
We can see 45 is a multiple of 15 such that
Therefore, Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3= 45 hours.
<em><u>Solution:</u></em>
Given that,
Actual volume of his bathtub is 37 gal
Estimate is 31 gal
<em><u>Find the absolute error</u></em>
Absolute Error = | Measured Value - Actual Value |
Absolute Error = | 31 - 37 |
Absolute Error = 6
<em><u>Find the percent error</u></em>
Substituting we get,
Negative sign means percent decrease
Thus percent error is 16.22 %
