1. Solve the absolute value equation, if possible.  If there is no solution, explain why.
| 5x + 13| = -7

Answers

Answer 1
Every absolute value MUST be 0 or greater (positive); thus, | 5x + 13| = -7 has no solution due to the - number on the right.

Answer 2
An absolute value of any real number is never negative.

The number on the right side, -7, is a negative number.

As I just stated, the absolute value can never be negative.

Since -7 is a negative number, there is no solution to this equation.

Have an awesome day! :)

Mr. Welch bought 24 ft of fencing.

How many yards of fencing did he buy? (1 yd = 3 ft)

Answers

1 yard = 3 feet

 divide 24 feet by 3 feet to get yards

24 / 3 = 8 yards

If Mr. Welch bought 24 ft. of fencing and 1 yd. is equal to 3 ft., then what we would do is divide 24 by 3 which equals 8. Therefore, he bought 8 yd. of fencing.

Triangle ABC is dilated with a center at the origin and a scale factor of 2. What are the coordinates of triangle A’B’C’?

Answers

The coordinates of triangle A'B'C' are A'(-4, 4), B'(2, 6) and C'(-2, 0).

Given that, triangle ABC is dilated with a center at the origin and a scale factor of 2.

What is a dilation?

Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor. The new figure obtained after dilation is called the image and the original image is called the pre-image.

From the given graph, A(-2,2), B(1, 3) and C(-1, 0)

By using a scale factor of 2, we get

A(-2,2)→2(-2, 2)=A'(-4, 4)

B(1, 3)→2(1, 3)=B'(2, 6)

C(-1, 0)→2(-1, 0)=C'(-2, 0)

Therefore, the coordinates of triangle A'B'C' are A'(-4, 4), B'(2, 6) and C'(-2, 0).

Use the sequence below to answer parts a and b (8,17,26,35,44,53,...) Create an explicit formula to determine the 12th term of the sequence Create a recursive formula to prove the 7th term is 62.

Answers

THATS HOW YOU SOLVE THE 12TH AND 7TH TERM
Final answer:

The explicit formula for the sequence (8, 17, 26, 35, 44, 53, ...) is 8 + (n-1) * 9, and the 12th term can be found by substituting n = 12. The recursive formula for the sequence is a1 = 8 and an = an-1 + 9. Using this recursive formula, we can verify that the 7th term is indeed 62.

Explanation:

To create an explicit formula for the sequence (8, 17, 26, 35, 44, 53, ...), we notice that the difference between each term is 9. So, the explicit formula for the sequence is 8 + (n-1) * 9, where n represents the position of the term in the sequence. Using this formula, we can find the 12th term by substituting n = 12: 8 + (12-1) * 9 = 89.

To create a recursive formula to prove that the 7th term is 62, we observe that each term is the previous term plus 9. So, the recursive formula for the sequence is:

a1 = 8an = an-1 + 9

Using this recursive formula and starting with a1 = 8, we can find the 7th term as follows:

a1 = 8a2 = a1 + 9 = 8 + 9 = 17a3 = a2 + 9 = 17 + 9 = 26a4 = a3 + 9 = 26 + 9 = 35a5 = a4 + 9 = 35 + 9 = 44a6 = a5 + 9 = 44 + 9 = 53a7 = a6 + 9 = 53 + 9 = 62

Therefore, the 7th term in the sequence is indeed 62.

Use two unit multipliers to convert 70 meters to inches.

Answers

70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in
.
Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2


I think that's how it's done. As far as explaining it goes, I can't do that. I had to ask my math teacher and she wrote the calculations down.
Final answer:

To convert 70 meters to inches, use the unit multiplier method. 70 meters is equal to 2755.91 inches.

Explanation:

To convert meters to inches, we can use the unit multiplier method. There are two unit multipliers we can use:

1 meter = 39.37 inches and 1 inch = 0.0254 meters.

Start with the given quantity of 70 meters.Multiply by the unit multiplier 39.37 inches / 1 meter. This will cancel out the meters and leave us with the equivalent value in inches.Multiply the result by the unit multiplier 1 meter / 0.0254 inches. This will cancel out the inches and convert the value back to meters.Simplify the expression to find the final answer.

Therefore, 70 meters is equal to 2755.91 inches.

An aquarium with a square base has no top. There is a metal frame. Glass costs 8 dollars/m^2 and the frame costs 7 dollars/m. The volume is to be 20 m^3. Express the total cost C in terms of the height h in meters. (Hint: work out the cost of the glass and frame separately.)

Answers

Given that the volume of the aquarium is 20m^3.

Volume = Area of Base x height

Area of Base = Volume / height = 20/h

Given that the aquarium has a square base.

Area of square = l^2

Thus, the length of the base of the aquarium is [tex] \sqrt{area \ of \ base} = \sqrt{ \frac{20}{h} } [/tex]

The frame is to cover 8 sides with the length equal to the length of the base and 4 sides with the length of the height.

Thus, the total perimeter of the frame is given by [tex]8\sqrt{\frac{20}{h}}+4h= \sqrt{64\left(\frac{20}{h}\right)}+4h = \sqrt{\frac{1,280}{h}}+4h [/tex]

Area of the four side faces of the aquarium is 4 times the length of the base times the height = [tex]4\times\sqrt{ \frac{20}{h} }\times h=\sqrt{16\left(\frac{20}{h}\right)h^2}=\sqrt{320h}[/tex]

Total area to be covered by grass is the base and the four side faces and is given by [tex]\frac{20}{h}+\sqrt{320h}[/tex]

Cost of the entire metal frame = [tex]7\left(\sqrt{\frac{1,280}{h}}+4h\right)= \sqrt{49\left(\frac{1,280}{h}\right)}+7(4h) = \sqrt{\frac{62,720}{h}}+28h [/tex]

Cost of the entire grass = [tex]8\left(\frac{20}{h}+\sqrt{320h}\right)=\frac{160}{h}+\sqrt{64(320h)}=\frac{160}{h}+\sqrt{20,480h[/tex]

Therefore, total cost in terms of the height, h, is given by

[tex]C=\sqrt{\frac{62,720}{h}}+28h+\frac{160}{h}+\sqrt{20,480h[/tex]

If there are 1000 grams in a kilogram and 454 grams in a pound, how many pounds are there per kilogram?

Answers

Answer:2.2 pounds per kilogram

Step-by-step explanation:

454gram = 1 pound

since; 1000g = 1kg

454g = x

x= 454/1000

x=0.454kg

there is 0.454kg in 1 pound

but the question says how many pound is in 1kg

0.454kg = 1 pound

1 kg = x

cross multiply

0.454x = 1

Divide bothside by 0.454

x = 1/0.454

x = 2.2 pound

Therefore; there are 2.2pounds in 1 kilogram.

There are 2.20 pounds are there per kilogram

Given that,

1 kg = 1000 gm

1 pound = 454 gm

Since we know that,

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Since,

1 pound = 454 gm

Therefore,

⇒ 454 gm = 1 pound

⇒       1 gm = 1/454 pound

And since,

1 kg = 1000 gm

       = 1000x(1/454) pound

       = 2.20 pounds

Hence,

1 kg = 2.20 pounds

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil. If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?

Answers

What we know:
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil.

What we need to find:
If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?

Set up a proportion to find how much natural oil is used.
7L natural oil/5L synthetic oil = x/355 synthetic oil where x=natural oil
7/5=x/355
(5)(x)=(7)(355) cross multiplied
5x=2485 simplified
5/5x=2485/5 multiplicative inverse
x=497L

Now, add both synthetic oil and natural oil to find amount of petrolyn oil.

355 L synthetic oil + 497 L natural oil= 852 L of petrolyn oil
