Answer:

1920

Step-by-step explanation:

What we can do is split this into two sections: the volume of the rectangle and the volume of the square.

Rectangle: We can follow the equation V = lbh, so we have 14x8x10, giving us 1120.

Square: We can use the same equation, V = lbh, giving us 10x10x8 which is 800.

Final Answer: To get the full volume, we have to add these together, so, 1120 + 800 = 1920.

HELP PLEASE If L is the line through the point (-3,5) having a slope of 2/3 . Complete the equation of L

nalin [4]

point slope form (y-y1) = m(x-x1)

y-5=(2/3)(x-(-3))

y-5=(2/3)(x+3) add 5 to each side and distribute

y= 2/3x +2/3 *3 +5

y = (2/3)x +2 +5

y = (2/3) + 7

Which number should each side of the equation 4/5x=8 be multiplied by to produce he equivalent equation of x=10?

gulaghasi [49]

<< Add $.\frac{-4}{5}$ to the left and right of the equation, multiple and make ''opposite multiplation'' to find x.

A) $\frac{4}{5x}. \frac{-4}{5} = 8. \frac{-4}{5} 
$
$\frac{16}{25x} = \frac{-32}{5}$
25x.(-32)= (-16).5
-800x= -80

**to leave x alone and positive, you must divide to -800.
$x= \frac{-80}{-800}$
$x= \frac{1}{10}$
= INCORRECT

B) $\frac{4}{5x} . \frac{1}{5} = 8. \frac{1}{5} 
$
$\frac{4}{25x} = \frac{8}{5}$
$25x.8= 4.5$
$200x=20
$
$x= \frac{20}{200} = \frac{1}{10}$

C) $\frac{4}{5x} . \frac{5}{4}= \frac{8.5}{4}$
$\frac{1}{x} = \frac{40}{4}$
$\frac{1}{x} =10$
10x=1
$x= \frac{1}{10}$

D) $\frac{4.5}{5x} = 8.5$
$\frac{4}{x} = 40$
40x= 4
x= $\frac{4}{40}$ = 1/10

I think there is a problem with the options :D

The legs of a right triangle are 5 units and 15 units. What is the length of the hypotenuse?

Varvara68 [4.7K]

To find the answer you have to use pythagorean theorem;

a² + b² = c² where a and b are the legs and c is the hypotenuse.

5² + 15² = c²

25 + 225 = c²

250 = c²

√250 = √c²

√250 = c

hope this helps, God bless!
