Solve [tex]\frac{-72}{x} = 9[/tex] using the distributive property.

Answer:

1134 cubic inches of soil

Step-by-step explanation:

You can split the shape apart and then add the volumes together at the end.

The bottom shape is 21x7x2

=294

The top shape is 12x10, and the last side can be foundfrom the other shape’s depth, 7.

12x10x7

=840

294+840=1134

Answer: The first option

What we know:

How to solve:

     By finding the perimeter of the fence in feet, we can check that value against the 4 proportion options listed in the problem. Whichever is true will be the correct answer.

Perimeter - in feet

Where P is perimeter in miles, x is perimeter in feet, w is width in miles, and L is length in miles.

Set up equation                                                     P = 2w + 2L

Substitute                                                               P = 2(1/8) + 2(1/4)

Simplify                                                                   P = 2/8 + 2/4

Common denominator                                          P = 1/4 + 2/4

Simplify                                                                   P = 3/4 mi.

Translate                                                                x = (3/4)*5280

Simplify                                                                   x = 3960 ft.

For the following: Where m represents the mile unit, f represents the foot unit, and x represents the number of feet of fencing.

First option

Set up equation                                            (3/4)m/x = m/5280f        

Equal variables                                         16[(3/4)m/x) = 12[m/5280f]

Simplify                                                             12m/16x = 12m/63360f

Remove miles                                                          16x = 63360f

Isolate x variable                                                    /16     /16

Solution                                                                       x = 3960 ft.

Second Option

Set up equation                                             (3/8)m/x = m/5280f

Equal variables                                         64[(3/8)m/x] = 24[m/5280f]

Simplify                                                              24m/64x = 24m/126720f

Remove miles                                                            64x = 126720f

Isolate x variable                                                      /64     /64

Solution                                                                          x = 1980 ft.

Third Option

Set up equation                                               x/(3/4)f = m/5280f

Equal variables                                      7040[x/(3/4)f] = m/5280f

Simplify                                                   7040x/5280f = m/5280f

Remove feet                                           7040x = m

Translate                                                 7040x = 5280f

Isolate x variable                                   /7040     /7040

Solution                                                           x = (3/4)f

Fourth Option

Set up equation                                             x/(3/8)f = m/5280f

Equal variables                                  14080[x/(3/8)f] = m/5280f

Simplify                                               14080x/5280f = m/5280f

Remove feet                                        14080x = m

Translate                                              14080x = 5280f

Isolate x variable                                /14080     /14080

Solution                                                         x = 3/8f

Check:

If the perimeter of the fence, in feet, is the first option, then when

x = 3960, the number of miles and feet should be equal. Let's test this.

(3/4)m/x = 1

(3/4)m/3960f = 1

(3/4)(5280f)/3960f = 1

3960f/3960f = 1

1 = 1

Therefore, option 1 is correct.

Answer:

5

Step-by-step explanation:

[tex]12 - 2(3h) = - 18 \\ 12 - 6h = - 18 \\ - 6h = - 18 - 12 \\ - 6h = - 30 \\ h = \frac{ - 30}{ - 6} \\ h = 5[/tex]

Answer:

H=5

Step-by-step explanation:

Simplifying the equation

We multiply 2(3H) =6H, so the equation is now 12-6H=-18

Isolating the Variables

Then, we subtract 12 from both sides, giving us -6H = -30

Finding H

Finally, we divide both sides by -6, so H= 5

Answer:

B. 150 ft

Step-by-step explanation:

Perimeter of a rectangle = 2(Length) + 2(Width)

Here, we are given the perimeter and width and we want to find the length

We can do so by plugging in what we are given into the perimeter formula and solving for length.

Perimeter = 2(Length) + 2(Width)

Perimeter = 450 and Width = 75

450 = 2(Length) + 2(75)

We now solve for length

==> simplify multiplication 2(75) = 150

450 = 2(Length) + 150

==> subtract 150 from both sides

300 = 2(Length)

==> divide both sides by 2

150 = Length

And we are done!

The answer is B 150ft

The volume of the prism shaped fish tank is: 408 in.³.

Volume of prism = base area × height of prism.

The fish tank is a prism having a height of 8 inches. To find its volume, find the base area, which is the area of the composite figrue given.

Thus:

Base area = area of rectangle + area of triangle = (length × width) + (1/2(base × height).

Given:

Therefore:

Base area = (7 × 6) + 1/2(3 × 6)

Base area = 51 in.²

Volume of the prism shaped fish tank = 51 × 8 = 408 in.³.

Step-by-step explanation:

The converse of the Pythagorean Theorem tells us that by comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.

To determine from the side lengths if a triangle is a right triangle. Therefore, the correct answer is option C.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

The converse of Pythagoras theorem states that “If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right angle triangle”.

By comparing the sum of the squares of two sides of a triangle to the square of its third side, we can determine whether that triangle is an acute, right, or obtuse.

So pretty much all u do is take the triangle and turn it to the right one rotation.

Step-by-step explanation:

Answer:

Radius: about 1.42 mm

Step-by-step explanation:

First, you divide the circumference (8.9) by 3.14, or π.

Cirucmference(8.9) divided by π(3.14) = the diameter (2.83439490446)

Diameter (2.83439490446) divided by 2 = radius (1.41719745223)

Now, you have to round to the nearest hundredth.

1.41719745223 rounded to the nearest hundredth is 1.42 because the second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

Answer:

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

3/4x+9=3

First, subtract by 9 from both sides.

3/4x+9-9=3-9

Solve.

3-9=-6

Rewrite the problem down.

3/4x=-6

Multiply by 4 from both sides.

4*3/4x=4(-6)

Solve.

3x=-24

Then, you divide by 3 from both sides.

3x/3=-24/3

Solve.

Divide these numbers goes from left to right.

-24/3=-8

x=-8

Variables and negative signs should appear in the answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

x = -8

Step-by-step explanation:

Subtract 9 both sides:

⇒ 3/4x + 9 = 3

⇒ 3/4x + 9 - 9 = 3 - 9

Simplify the L.H.S and the R.H.S:

⇒ 3/4x = -6

Use cross multiplication:

⇒ 3x/4 = -6

⇒ 3x = -6 × 4

Simplify the R.H.S:

⇒ 3x = -6 × 4

⇒ 3x = -24

Divide 3 both sides:

⇒ 3x/3 = -24/3

⇒ x = -8

1 hours → 75 miles

? hours → (1125/75)

It takes her 15 hours to drive 1125 miles.

Answer:

15 hours

Step-by-step explanation:

Finding how much distance in 1 hour

⇒ Ceci = 225 miles = 3 hours

⇒ 225 miles = 3 hours

⇒ 225/3 miles = 3/3 hours

⇒ (25 x 9)/3 miles = 1 hour

⇒ (25 x 3) miles = 1 hour

⇒ 75 miles = 1 hour

Finding how much hours in 1125 miles

⇒ 75 miles = 1 hour

⇒ 75x miles = 1125 miles = x hours

⇒ 75x/75 = 1125/75

⇒ x = 15

⇒ 75(15) miles = 1125 miles = (15) hours

⇒ 1125 miles = (15) hours

Answer:

$0.50/muffin

Step-by-step explanation:

To find the unit rate we have to find out how much 1 muffin costs:

To do this we can divide both sides by 7:

7÷7 for 3.50÷7

1 muffin for 0.50

Therefore our answer is $0.50/muffin

Answer:

$0.50 / muffin

Step-by-step explanation:

7 muffins for $3.50

To find the unit rate, we need to find what 1 muffin costs.

so

1 muffin = 3.5/7 = 0.5

$0.50 per muffin.
