3/10 because 2/5 is also equal to 4/10 so therefore 3/10 is smaller than 4/10

Using V = lwh, what is an expression for the volume of the following prism? The dimensions of a prism are shown. The height is S

Lubov Fominskaja [6]

<h2>Explanation:</h2><h2></h2>

We know that the volume of a prism is defined by:

$V=lwh \\ \\ \\ Where: \\ \\ l:length \\ \\ w:width \\ \\ h:height \\ \\ \\ l=\frac{d-2}{3d-9} \\ \\ w=\frac{4}{d-4} \\ \\ h=\frac{2d-6}{2d-4}$

Substituting values:

$V=\left(\frac{d-2}{3d-9}\right)\left(\frac{4}{d-4}\right)\left(\frac{2d-6}{2d-4}\right) \\ \\ \\ Simplifying: \\ \\ V=\frac{d-2}{3d-9}\cdot \frac{4}{d-4}\cdot \frac{d-3}{d-2} \\ \\ V=\frac{\left(d-2\right)\cdot \:4\left(d-3\right)}{\left(3d-9\right)\left(d-4\right)\left(d-2\right)} \\ \\ V=\frac{4\left(d-3\right)}{\left(3d-9\right)\left(d-4\right)} \\ \\ V=\frac{4\left(d-3\right)}{3\left(d-3\right)\left(d-4\right)}$

$Finally: \\ \\ \boxed{V=\frac{4}{3\left(d-4\right)}}$

What does p equal? P+2/p+7=3/6

zloy xaker [14]

$\bf \cfrac{p+2}{p+7}=\cfrac{3}{6}\implies \cfrac{p+2}{p+7}=\cfrac{1}{2}\implies 2(p+2)=1(p+7)\implies 2p+4=p+7 \\\\\\ p+4=7\implies p=3$

A research organization studying families in various countries reported the following data for the amount of time that children

uysha [10]

Answer:B. 42, 43

Step-by-step explanation:

STEP 1 Listing out the data set

Country Time with dad

Belgium 30

Canada 44

China 54

Finland 50

Germany 36

Nigeria 42

Sweden 46

United States 42

STEP 2--- finding the mode and median

Mode----The mode of this data set is the number that occurs most frequently in this research date.

Time with dad in ascending order is given as 30, 36, 42, 42, 44,46,50,54

The number that occurred the most is 42 = mode

Median The median is the middle value in a data set

Since these data set is an even number, we take the average of the two middle numbers

Arranging in ascending order, we have

30, 36, 42, 42, 44, 46, 50, 54---------------42 and 44 are the middle numbers

42+ 44/2 =43

Therefore mode and median are 42 and 43 respectively
