M = (0, 0), which IS the origin

**Step-by-step explanation:**

The midpoint is given by the formula ...

M = (A + B)/2

M = ((4, -6) +(-4, 6))/2 = (4-4, -6+6)/2 = (0, 0)/2

** M = (0, 0) . . . . . IS the origin**

A cylindrical tank has a height of 10 feet and a radius of 4 feet. Carla fills the tank with water at a rate of 8 cubic feet per minute. At this rate, how many minutes will it take Carla to completely fill the tank without it overflowing? Round your answer to the nearest minute.

Area = 10(pi)(16) = 160pi cubic feet

160pi = 502.56

502.56/8 = 63 minutes

160pi = 502.56

502.56/8 = 63 minutes

The **time **it will take for Jane to **completely **fill the tank without overflowing would be 62.8 minutes.

Used the concept of the **volume **of the cylinder:

The volume of the cylinder can be determined using the formula,

[tex]V = \pi r^2h[/tex]

Given:

A **cylindrical tank** has a height of 10 feet.

The radius of the cylindrical tank is 4 feet.

Jane fills the tank with **water **at a rate of 8 cubic feet per minute.

Since, the **volume **of the cylinder:

[tex]V = \pi r^2h[/tex]

Substituting the values, we have;

[tex]V = 3.14 \times 4^2 \times 10[/tex]

[tex]V = 502.4 \tex{ feet^3 }[/tex]

Thus, the volume of the cylinder is 502.4 cubic feet.

Time taken:

The **time **taken can be determined using the formula,

[tex]\text{Time} = \dfrac{\text{Volume}}{\text{Rate of filling}}[/tex]

Substituting the values, we have;

[tex]\text{Time} = \dfrac{\text{502.4}}{\text{8}}[/tex]

[tex]\text{Time} = 62.8[/tex]

Thus, **Jane **takes 62.8 minutes to completely fill the tank without overflowing it.

What is the value of x in 7x-18

**Answer:**

x = 21

**Step-by-step explanation:**

Although the picture is a bit blurry towards the bottom, I believe the opposite exterior angle is 129°

Opposite exterior angles are equivalent by the opposite exterior angles postulate. Of course, this only applies if the transversed lines are parallel, which they are in this case, because of the small orange arrows.

Anyhow, the equation should be set up as follows:

[tex]129 = 7x-18\\129 + 18 = 7x - 18 +18\\147 = 7x\\21=x[/tex]

At least pet snake is 42 inches long and Royals pet snake is 8 feet long.How many inches longer is Royals snake

Answer:

54 inches

Step-by-step explanation:

Step 1

We would be converting the length of the Royal's pet snake to inches

1 foot = 12 inches

8 feet = x

Cross Multiply

x = 8 × 12 inches

x = 96 inches

Step 2

How many inches longer is Royal's snake?

This is calculated by subtracting the length of the Royal's pet snake from the least length

= 96 inches - 42 inches

= 54 inches

Therefore, the Royal's snake is 54 inches longer

Which is the most accurate way to estimate 26% of 91?

A: 3/4 x 92

B: 1/4 x 92

C: 1/3 x 90

D: 1/2 x 90

**Answer:**

B

**Step-by-step explanation:**

26% is close to 25%, which is equal to 1/4th.

You're adding to the number and removing from the percentage so it balances it out.

The **estimation **of 26% of 91 is 1/4 x 92.

The **correct **option is (B).

To determine the quantity or percentage of something in terms of 100, use the percentage formula. **Per cent **simply means **one **in a **hundred**. Using the percentage formula, a number between 0 and 1 can be expressed. A **number **that is **expressed **as a **fraction **of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

26% of 91

Now **solving **the above **Quantity**

= 26 /100 x 91

Now, We take 1 from 26 make it 25 and **add **that 1 to 91 make 92.

Then, 25 / 100 x 92

= 1/4 x 92

Hence, the **estimation **is 1/4 x 952.

A small factory is considering replacing its existing coining press with a newer, more efficient one. The existing press was purchased three years ago at a cost of $200000, and it is being depreciated according to a 7-year MACRS depreciation schedule. The factorys CFO estimates that the existing press has 6 years of useful life remaining. The purchase price for the new press is $280000. The installation of the new press would cost an additional $20000, and this installation cost would be added to the depreciable base. The new press (if purchased) would be depreciated using the 7-year MACRS depreciation schedule although, as noted below, it would be retired/sold after 6 years. Interest expenses associated with the purchase of the new press are estimated to be roughly $4000 per year for the next 6 years.The appeal of the new press is that it is estimated to produce a pre-tax operating cost savings of $81000 per year for the next 6 years. Also, if the new press is purchased, the old press can be sold for $30000 today. The CFO believes that the new press would be sold for $45000 at the end of its 6-year useful life. Assume that NWC would not be affected. The company has an average tax rate of 29% and a marginal tax rate of 34%. The cost of capital (i.e., the discount rate) for this project is 8.5%.Required:Develop the incremental cash flows for this replacement decision and use them to calculate NPV and IRR. Next, make a conclusion about whether or not the existing coining press should be replaced at this time.
