Find the volume of the prisms. Show work!

Fed [463]

1. Answer = About 1451.42 m³

First, we need to find the volume of the cube:
Formula: πr²h

Volume = π * 3² * 50 = 1413.72 m³
Second, we need to find the volume of the cone:
Formula: (πr²h)/3
Volume = π * 3² * 4 = 37.69 m³
Third, we need to add these two volumes to find the total volume of the figure.

1413.72 m³ + 37.69 m³ = 1451.42 m³.

2. Answer <em>= </em>960 m³

Formula: (1/2(b*l)) * 20
First, we need to find the area of the base (1/2 * b* l).
1/2 * 8 * 12 = 48.
Second, we need to multiply the area of the base by the height to get the volume.
B * h = 48 * 20 = 960 m³.

A store is having a sale in which all items are reduced by 20%. Including tax, Jennifer paid $21 for a pair of shorts. If the sa

Tju [1.3M]

Answer: the original price of the shorts was $25

Step-by-step explanation:

Let x represent the original price of the shorts.

The store is having a sale in which all items are reduced by 20%. This means that the amount of discount on the shorts is

20/100 × x = 0.2x

The price of the shorts would be

x - 0.2x = 0.8x

If the sales tax is 5%, then the amount of sales tax charged is

5/100 × 0.8x = 0.04x

The final cost of the shorts would be

0.8x + 0.04x = 0.84x

Including tax, Jennifer paid $21 for a pair of shorts. This means that

0.84x = 21

x = 21/0.84

x = 25

1.Solve the equation. Check for extraneous solutions.

elena55 [62]

Okay so I did the math.

1. Two solutions were found :<span><span>
z=-1
</span><span>z=2/3
</span></span><span>Step 1 :</span>Rearrange this Absolute Value Equation

Absolute value equalitiy entered
|2z-3| = 4z-1

<span>Step 2 :</span>Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is<span> |2z-3|

</span>For the Negative case we'll use -(2z-3)

For the Positive case we'll use (2z-3)

<span>Step 3 :</span>Solve the Negative Case

      -(2z-3) = 4z-1

     Multiply
      -2z+3 = 4z-1

     Rearrange and Add up
      -6z = -4

     Divide both sides by 6
      -z = -(2/3)

     Multiply both sides by (-1)
      z = (2/3)
     Which is the solution for the Negative Case

<span>Step 4 :</span>Solve the Positive Case

      (2z-3) = 4z-1

     Rearrange and Add up
      -2z = 2

     Divide both sides by 2
      -z = 1

     Multiply both sides by (-1)
      z = -1
     Which is the solution for the Positive Case
Step  5  :Wrap up the solution

<span> z=2/3
</span><span> z=-1

2. </span>-6 < x < 26/3

<span>Step 1 :</span>Rearrange this Absolute Value Inequality

Absolute value inequalitiy entered
|3x-4|+5 < 27

Another term is moved / added to the right hand side.

|3x-4| < 22

<span>Step 2 :</span>Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is<span> |3x-4|

</span>For the Negative case we'll use -(3x-4)

For the Positive case we'll use (3x-4)

<span>Step 3 :</span>Solve the Negative Case

      -(3x-4) < 22

     Multiply
      -3x+4 < 22

     Rearrange and Add up
      -3x < 18

     Divide both sides by 3
      -x < 6

     Multiply both sides by (-1)
     Remember to flip the inequality sign
      x > -6
     Which is the solution for the Negative Case

<span>Step 4 :</span>Solve the Positive Case

      (3x-4) < 22

     Rearrange and Add up
      3x < 26

     Divide both sides by 3
      x < (26/3)

     Which is the solution for the Positive Case

<span>Step 5 :</span>Wrap up the solution

-6 < x < 26/3

Solution in Interval Notation

(-6,26/3)

Darlene wants to buy a sweater that originally cost 32$ it is on sale for 20% off. Sales tax is 6.75%. What is the final price o

AURORKA [14]

Answer:

<h3>$27.34</h3>

Step-by-step explanation:

32 x 0.20 = $6.40

32 - 6.4 = $25.60

25.6 x .0675 ≈ 1.738

25.6 + 1.738 = 27.338 ≈$27.34

MrRa [10]

Answer:

676 assuming the population is 3800 in 2019. If it's a different year then change t.

Step-by-step explanation:

$P(t) = P_{0} (1+r)^t \\\\P(6) = 3800(1-.25)^6 \\=P(6) = 3800(.75)^6\\=676$
