Find the height of the figure below with the given volume .
Dennis_Churaev [7]

Answer:

h = 8

Step-by-step explanation:

The formula for the volume of a prism is:

V = l x w x h

In this case, both your length and width are the same (8in).

You plug the numbers into the formula to get:

512 in³ = 8 in · 8 in ·h

512 = 64 · h

h = 8

Also, while the figure doesn't say to scale, it looks like a cube. So I probably would've went ahead and tried 8³ to see if it worked out lol!

Good luck ~

Find the point of intersection of the pair of straight lines.
Ber [7]

Answer:

(x,y) = (\frac{9}{2},\frac{1}{2})

Step-by-step explanation:

We have to find point of intersection of two lines.

the given equations of line are:

10x - 4y = 43 - (1)

-3x - 3y = -15 - (2)

Multiplying the first equation by 3 we have:

(10x - 4y = 43)×3 = 30x - 12 y = 129 - (3)

Multiplying second equation by 10 we have :

(-3x - 3y = -15)×10 = -30x -30y = -150 - (4)

Now, adding equation (3) and (4)  we have:

-42y = -21

⇒ y = \frac{1}{2}

Now, putting this value of y in equation (1), we have

10x - 2 = 43

⇒ 10x = 45

⇒x = \frac{9}{2}

Hence, the intersection of given two lines is (x,y) = (\frac{9}{2},\frac{1}{2})

Nathaniel buys 28 gallons of gas for $56. He will put some more gas in his tank again
Serggg [28]

Answer: 19.5 gallons

Step-by-step explanation:

Hi, to answer this question, we have to use proportions:

Nathaniel buys 28 gallons of gas for $56, so the proportion is:

$56 / 28 gallons.

For $39:

$39 / x gallons

Solving for x (number of gallons)

56/28 = 39/x

x = 39 / (56/28)

x = 19.5 gallons

Feel free to ask for more if needed or if you did not understand something.
