does anybody know how to find the volume of. a prism. please help

Answer:

x = 3, y = 1

Step-by-step explanation:

By substitution since y = -2x + 7, substitute that for the 2nd y so

-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1

If you use elimination you can subtract the two equations from each other to get rid of the y so

y = -2x + 7

-y = -3x + 8

so 0 = -5x + 15, 5x = 15, x=3

<HAM+<HAJ=180 LINEAR PAIR

<HAM=180-<HAJ=180-42=138IS YOURANSWER

Answer:

138°

Step-by-step explanation:

∠JAM = 180°

∠JAH = 42°

∠JAH + ∠HAM = 180° because they are supplementary

42° + ∠HAM = 180°

∠HAM = 180°-42°

∠HAM = 138°

Answer:

a) It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are: A(-2, -1)

b) We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

c) The coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]        

Step-by-step explanation:

Part a)

Important Tip:

It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are:

Part b)

We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

Part c)

We can determine the coordinates of the midpoint of AB using the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

In our case, we have:

A(x₁, y₁) = A(-2, -1)

B(x₂, y₂) = B (-2, 4)

so substituting [tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex] in the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

            [tex]=\left(\frac{-2-2}{2},\:\frac{4-2}{2}\right)[/tex]

Refine

            [tex]=\left(-2,\:\frac{3}{2}\right)[/tex]

Therefore, the coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]          

Answer:

0.015625

Step-by-step explanation:

The probability that Nick wins at least once is 2.5

"Probability is finding out the possibilities of the occurrence of an event."

"P(A) = n(A) / n(S)

where, n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment"

"It is a number that can be expressed as a fraction of 100."

For given example,

Nick has a 25 percent chance of winning on any individual.

This means, his chances of winning on any individual spin are 0.25

Individual spins are independent and Nick decides to play the game 10 times.

So the probability that Nick wins at least once is 10 × 0.25 = 2.5

Therefore, the probability that Nick wins at least once is 2.5

Answer:

22.5 cans of paint

Step-by-step explanation:

[tex]n=3*10*\frac{3}{2*2} =30*\frac{3}{4} =22.5 cans[/tex]

Answer:

You need 22.5 cans of paint to paint 10 walls with 3 layers.

Step-by-step explanation:

[tex]\frac{3}{2*2}[/tex] = 0.75 (Represents how many cans of paint it takes to paint 1 wall with 1 layer)

0.75 * 10 * 3 = 7.5 * 3 = 22.5 (The number of paint needed for 1 wall with 1 layer multiplied by 10 walls with 3 layers to get the total amount of paint needed)

Answer:

y = -2x + 3.

Step-by-step explanation:

The slope = (11-3)/(-4-0)

= 8/-4

= -2.

Using the point-slope form of a straight line:

y - y1 = m(x - x1)

Here m = -2 and (x1, y1) = (0,3). then

y - 3 = -2(x - 0)

y - 3 = -2x

y = -2x + 3.

Answer:

y = (10 * 0.2) ^ x

Y = (2)^x

Y =  2^x + 10

6.5 hours

Step-by-step explanation:

Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

EMI on $1000 is $8.78, so EMI on $1 is

EMI on $1 = 8.78/1000 = 0.00878

EMI on $50150 is

EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32

Therefore the correct option is a.

Answer:

6m

Step-by-step explanation:

You need to use trigonomtery: SOHCAHTOA

Since we are looking for the height, we should use the Sine rule:

Sine(37) = opposite/hypotenuse

We already have our hypotenuse which is 10

sine(37) = opposite/10m

Now we re-arrange to find the opposite(which is our height)

opposite = 10m x sine(37)

opposite = 6.018

Therefore height = 6 to the nearest metre

[tex]144[/tex] cubic units

Step-by-step explanation:

We can assume that the truck is a rectangular prism since we're given its length, width, and height. To find the volume of a rectangular prism, simply multiply its length, width, and height together. As an algebraic expression, this would be [tex]l*w*h[/tex], where [tex]l[/tex], [tex]w[/tex], and [tex]h[/tex] are the prism's length, width, and height, respectively.

In this case, we are given that [tex]l=6[/tex], [tex]w=4[/tex], and [tex]h=6[/tex]. Therefore, the volume of the milk truck is [tex]6*4*6=144[/tex] cubic units. Hope this helps!

Answer: 144 feet³

Step-by-step explanation: To find the volume, mutiply the Length, Width, and Height. Or we can use the formula.

Rectangular Tank Volume Formula: L x W x H

As we see, 6 is the Length. 4 is the Width and 6 is the Height.

So, we can multiply the Length, Width, and Height to get the volume.

6 x 4 x 6 = 144 feet³

Therefore, the answer is 144 feet³

Answer:

Option c = [tex]\sqrt[9]{3}[/tex]

Step-by-step explanation:

One side = 18

Bottom side = 18 (equalateral triangle)

we can use phytagorues theorum:

a = the altitude (unknown)

b= one side (half of the bottom side) = 18/2 = 9

c = hypothenus = 18 (given)

a^2 + b^2 = c^2

a^2 + 9^2 = 18^2

a^2 = 18^2 - 9^2

   a^2  = 243

a = [tex]\sqrt{243}[/tex] = [tex]\sqrt{ 3 x 3 x 3 x 3 x 3 }[/tex] = [tex]\sqrt[9]{3}[/tex]
