Can anyone help me pls I will mark brainlist !! :)))
Kay [80]

Answer:

14 inches

Step-by-step explanation:

The volume of a rectangular prism is V=l*w*h

Given the info in the problem, we have:

840=l*10*6

840=60l

14=l

The length of the prism is therefore 14 inches because volume is length*width*height and since we already have the volume, height, and width, we need to get the variable for length by itself.

Find the Missing point, given the slope. (Hint: Set up an equation and solve) (-2, y^1), (6, 7) Slope = 1/2
ziro4ka [17]
<span>(-2, y1), (6, 7) Slope = 1/2

slope = (y2-y1)/(x2-x1)
1/2 = (7 - y1) / (6 - -2)
1/2 = (7-y1) / 8
7-y1  = 8/2
7-y1 = 4
y1 = 7 - 4
y1 = 3

Answer: </span><span>(-2, 3), (6, 7) with Slope = 1/2

</span>proof:
slope = (y2-y1)/(x2-x1)
slope =  (7 - 3) / (6 - -2)
slope = 4/8
slope = 1/2

Write the equation of the line that is perpendicular to y=2x-7 that passes through (3,1)
Finger [1]

Answer:

y=-1/2x-1/2

Step-by-step explanation:

For this, you need to use the point slope formula, (y-y1)=m(x-x1). The slope, m, would be -1/2 since the line we're looking for is perpendicular (meaning the slope is the negative reciprocal of the original slope). The x1 would be 3, and the y1 would be 1.

(y-y1)=m(x-x1)

(y-1)=-1/2(x-3)

y-1=-1/2x-3/2

y=-1/2x-1/2

Describe whether the rates are equivalent.
GaryK [48]
To get whether they are equal you have to cross multiply the numbers 18x16 and 48x3

48x3= 144

16x18= 288

144 is not equal to 288.

Therefore the rates aren’t equivalent.
