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 = \frac{4}{0.25} = 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

Solve the given system. y = x 20 y = 6x
adelina 88 [10]
If you would like to solve the following system, you can calculate this using the following steps:

y = x - 20
y = 6 * x
_________
6 * x = x - 20
6 * x - x = -20
5 * x = -20    /5
x = -4

y = 6 * x = 6 * (-4) = -24

If you would like to solve the following system, you can calculate this using the following steps:

y = x + 20
y = 6 * x
_________
6 * x = x + 20
6 * x - x = 20
5 * x = 20    /5
x = 4

y = 6 * x = 6 * 4 = 24

Chang is estimating the volume of his bathtub the actual volume of his bathtub is 37 gal chang’s estimate is 31 gal find the abs
stepladder [879]
<h3>The absolute error is 6</h3><h3>The percent error is 16.22 %</h3>

<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>

Percent\ error = \frac{\text{estimate - actual}}{actual} \times 100

Substituting we get,

percent\ error = \frac{31-37}{37} \times 100\\\\percent\ error = \frac{-6}{37} \times 100\\\\percent\ error = -16.22

Negative sign means percent decrease

Thus percent error is 16.22 %
