Here is my question: 2n + 4 = 4n + 1 - 2n
(keep in mid it's either an infinite solution, 0, or 1)

Answers

Answer 1

Answer:

0 solutions

Step-by-step explanation:

2n + 4 = 4n + 1 - 2n

                        ↑

first combine like terms (right side)

2n + 4 = 2n + 1

but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.

Answer 2

No Solution.

Once you combine the like terms 4n-2n of the second equation you end up with

2n+4 = 2n+1.

There is no value of n that results in a true equation.

Maria had 4 full cement, blocks & one that was 5/9 the normal size, If each full block weight 3 8/9 pounds, What is the Weight blocks maria has? (20 POINTS!)

Answers

I have no idea I hope you find the awnser though

The total Weight blocks maria has is 15.2 pounds.

What is Fraction?

A fraction represents a part of a whole.

Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.

Each full block weight [tex]3\frac{8}{9}[/tex] pounds

We need to find the Weight blocks maria has

Let us convert the mixed faction to improper fraction

35/9 = [tex]3\frac{8}{9}[/tex]

As there are 4 full cement, blocks

So multiply 4 with  [tex]3\frac{8}{9}[/tex]

4×35/9

4×3.8

15.2

Hence,  the total Weight blocks maria has is 15.2 pounds.

Toby is installing a new storage building in the back of his yard. The building measures 10 ft. x 12 ft. He’ll need a 10 foot long, 12 foot wide, and 4 inch deep slab for the project. Help him estimate the cost of his concrete project.

Answers

Answer:

Not sure if this is correct but i believe the price would be $20,000

Step-by-step explanation:

Yoour perimeter is 120ft and it is 1/3 of a foot. So i did 120/3 and i got 40. The 40 is how many square feet you will need. you do 40x500 and i got $20,000. Sorry if this is wrong as i was kind of confused for a moment

The required cost of the concrete project is given as $740.7.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

Here,
The volume of the slab is given as,
= length × width × height
= 10 × 12 × 4/12
= 40 cubic feet,

Now,
The cost of a concrete slab is given by
= Total volume (cubic foot) x $500/27
= 40 × 500 / 27
= $740.7

Thus, the required cost of the concrete project is given as $740.7.

What steps would you take in order to solve the equation 38 = 6x – 16? subtract 16 and then divide by 6 divide by 6 and add 16 add 16 and divide by 6 multiply by 6 and add 16

Answers

Answer:

x = 9

Step-by-step explanation:

38 = 6x - 16

Situate the x to one side -6x = -16-38

-6x = -54

-x = -9

x = 9

Isolate x by adding 16 to both sides of the equation to get 54=6x.

Then, divide birth sides of the equation by 6 to get 9=x, or x=9.

Croft Company (AJC) currently has $200,000 market value (and book value) of perpetual debt outstanding carrying a coupon rate of 6 percent. Its earnings before interest and taxes (EBIT) are $100,000, and it is a zero-growth company. AJC's current cost of equity is 8.8 percent, and its tax rate is 40 percent. The firm has 10,000 shares of common stock outstanding selling at a price per share of $60.00.1. What is AJC's current total market value and weighted average cost of capital?2. The firm is considering moving to a capital structure that is comprised of 40 percent debt and 60 percent equity, based on market values. The new funds would be used to replace the old debt and to repurchase stock. It is estimated that the increase in riskiness resulting from the leverage increase would cause the required rate of return on debt to rise to 7 percent, while the required rate of return on equity would increase to 9.5 percent. If this plan were carried out, what would be AJC's new WACC and total value?3.

Now assume that AJC is considering changing from its original capital structure to a new capital structure that results in a stock price of $64 per share.
