Work out the volume for this prism

melisa1 [442]

<h3>given:</h3>

$area = 24 \: {cm}^{2}$

$height = 8 \: cm$

the volume of the given prism.

<h3>solution:</h3>

$v = area \: of \: cross \: section \times height$

$v = 24 \times 8$

$v = 192 \: {cm}^{3}$

hence, the volume of the prism is 192 cubic centimeters.

If 6x=9y find the value of x:y.

Ad libitum [116K]

Answer:

A complete angle is one which measures 360∘360∘.

The three angles

6x+20∘,9y+30∘,3z+40∘6x+20∘,9y+30∘,3z+40∘

add up to 360∘360∘, as per the question.

6x+20∘+9y+30∘+3z+40∘=360∘6x+20∘+9y+30∘+3z+40∘=360∘

⟹3(2x+3y+z)+90∘=360∘⟹3(2x+3y+z)+90∘=360∘

⟹3(2x+3y+z)=270∘⟹3(2x+3y+z)=270∘

⟹2x+3y+z=90∘⟹2x+3y+z=90∘

This is the required relation.

Use the whole numbers 1 through 9 only one time each to find the largest possible value for x

Verdich [7]

Answer:

x=9

Step-by-step explanation:

1(x)+0=9

Why?

Because the larger the coeffient, the smaller x gets.

1x=9

x=9

2x=9

x=4.5

3x=9

x=3

You wouldn't want to add any number either, but conviniently, whole numbers also include 0

Bill mixes candy costing 45cents per pound with candy costing 65cents a pound. A 7-pound box of the mix costs $3.65. How much of

Len [333]

Answer:

Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.

Step-by-step explanation:

With the information provided, you can say that the sum of the pounds of each type of candy is equal to 7, which can be expressed as:

x+y=7

Also, the statement indicates the 7 pound box costs $3.65 and you can say that the sum of the results of multiplying the price of each candy for the number of pounds is equal to $3.65, which is:

0.45x+0.65y=3.65

You have the following equations:

x+y=7 (1)

0.45x+0.65y=3.65 (2)

Now, you have to solve for x in (1):

x=7-y (3)

Then, you have to replace (3) in (2):

0.45(7-y)+0.65y=3.65

3.15-0.45y+0.65y=3.65

0.20y=0.50

y=0.50/0.20

y=2.5

Finally, you can replace the value of y in (3) to find x:

x=7-y

x=7-2.5

x=4.5

According to this, the answer is that Bill should use 4.5 pounds of the candy costing 45 cents and 2.5 pounds of the candy costing 65 cents.
