Given: K=2∙33∙11∙172and M=3∙11∙173<br><br> Evaluate 18·M÷K.

gayaneshka [121]

Answer:

1557/1892

Step-by-step explanation:

Your calculator can do this:

$\dfrac{18M}{K}=\dfrac{18\cdot 3\cdot 11\cdot 173}{2\cdot 33\cdot 11\cdot 172}=\dfrac{18\cdot 173}{2\cdot 11\cdot 172}\\\\=\dfrac{1557}{1892}$

Nati randomly selected 10 girls and 10 boys from her 7th grade class and recorded their heights in inches. The results are shown

Georgia [21]

Answer:

Mean= 59.8 and median = 59.5

Step-by-step explanation:

Mean = Summation of values/ No. of Values

Mean of Girls' height= 61+58+63+57+58+59+62+64+60+56/10

Mean= 598/10= 59.8

Arranged Data = { 56, 57,58,58,59, 60, 61,62,63,64}

As the number of observations is even so the 5th and 6th value will be added and divided by 2

59+60/2= 59.5

Median = 59.5

In a parallelogram WXYZ , W and X are adjacent interior angles the measure of X is three times the measure of W which equation g

Andrew [12]

Answer:

The required equation is $\angle W+3\angle W=180^{\circ}$ .

Step-by-step explanation:

Given information: WXYZ is a parallelogram, W and X are adjacent interior angles and measure of X is three times the measure of W.

According to the properties of parallelogram, the two adjacent interior angle are supplementary angle and their sum is 180 degrees.

$\angle W+\angle X=180^{\circ}$ .... (1)

It is also given that the measure of X is three times the measure of W.

$\angle X=3\angle W$

Substitute this value in equation 1.

$\angle W+3\angle W=180^{\circ}$

$4\angle W=180^{\circ}$

$\angle W=45^{\circ}$

Substitute this value in equation 1.

$\angle W=135^{\circ}$

Therefore the required equation is $\angle W+3\angle W=180^{\circ}$ .
