Answer: Hello mate!

we have the equation 3x-7y=-28  and we want to solve it for y.

This is equivalent to isolate y in one side of the equation, lets do this:

3x-7y=-28

we subtract 3x in both sides of the equation.

3x -7y -3x = -28 - 3x

-7y = -28 - 3x

now we can divide both sides by -7.

-7y/(-7) = (-28 - 3x)/-7

y = (28 + 3x)/7 = (3/7)x + 4

And now there is the equation y(x).

Answer: 213 meters.

Step-by-step explanation:

A=2(wl+hl+hw) is the formula. l = 6, w = 3.5, h = 9 for this problem.

2([3.5 x 6]+[9 x 6]+[3.5 x 9])

2(21+54+31.5)

2(106.5)

A=213

Sorry if this isn’t a great explanation. Hope this helps.

What's the volume of this rectangular prism?
Snowcat [4.5K]

1. Find the length, width, and height of the rectangular prism.
2. Multiply the length, width, and height.
3. Write the answer in cubic units. For example: 60 inches3.

The length is the longest side of the flat surface of the rectangle on the top or bottom of the rectangular prism.

Ex: Length = 5 in.

<span>The width is the shorter side of the flat surface of the rectangle on the top or bottom of the rectangular prism. <span>Ex: Width = 4 in.The height is the part of the rectangular prism that rises up. Imagine that the height is what stretches up a flat rectangle until it becomes a three-dimensional shape. <span>Ex: Height = 3 in.You can multiply them in any order to get the same different result. The formula for finding the volume of a rectangular prism is the following: Volume = Length * Height * Width, or V = L * H * W. <span>Ex: V = 5 in. * 4 in. * 3 in. = 60 in.Since you're calculating volume, you're working in a three-dimensional space. Just take your answer and state it in cubic units. Whether you're working in feet, inches, or centimeters, you should state your answer in cubic units. <span>60 will become 60 in3.</span></span></span></span><span><span><span><span>

The average number of Saturday night shootings is 5 a night. What’s the chance that there will be a need for exactly 3 shootings
pishuonlain [190]

Answer:

0.14

Step-by-step explanation:

Using the poisson probability relation :

P(x = x) = (λ^x * e^-λ) ÷ x!

From the question ; mean, λ = 5 ; x = 3

Hence,

P(x = 3) = (5^3 * e^-5) ÷ 3!

P(x = 3) = (125 * 0.0067379) / 6

P(x = 3) = 0.8422375 / 6

P(x = 3) = 0.140
