Big Brothers, Inc. borrows $267,999 from the bank at 18.16 percent per year, compounded annually, to purchase new machinery. This loan is to be repaid in equal annual installments at the end of each year over the next 10 years. How much will each annual payment be?

Round the answer to two decimal places.

Answers

Based on the amount borrowed and the interest per year, Big Brothers, Inc will pay an annual payment of $59,973.15.

How much will Big Brothers, Inc. pay annually?

This can be found by using the present value of an annuity formula because the annual payment will be constant and therefore like an annuity.

Formula is:

Present value of annuity = Annual payment x ( 1 - (1 + rate) ^ -number of periods) / rate

Solving gives:

267,999 = Amount x ( 1 - ( 1 + 18.16%)⁻¹⁰) / 18.16%

267,999 = Amount x 4.46865

Amount = 267,999 / 4.46865

= $59,973.15

Answers

The number tablets per dose of drug A to be administered on the patient is 4 tablets

Quantity conversion

1 gram = 1000 milligram

Drug A provided = 1 gramDose = 250 milligram

Number of tablets to administer = Drug A provided / Dose

= 1 gram / 250 milligram

= 1000 milligram / 250 milligram

Number of tablets to administer = 4 tablets

Therefore, the number tablets per dose of drug A to be administered on the patient is 4 tablets

The perimeter of a rectangle is 42 inches if the width of the rectangle is 6 inches what is the length

Answers

Answer:

The length would be 15 inches.

Step-by-step explanation:

Since we are solving for perimeter the first step would be doing 6+6 = 12 (covering 2 sides). The next thing we would do is subtract 12 from 42 getting 30 as our answer. We need to divide 30 by 2 to get an answer of 15. I hope this helps! :)

What is the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1? m Y 1 77](V₂ − V₁] + V₁ m+n -8 -5 0 6

Answers

The y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

How to carry out division of line segments?

From the attached line segment graph, we see the coordinates as;

J (1, -10) and K (7, 2)

Let us assume that, point L divides the directed line segment from J to K into a ratio of 5:1.

From the properties of coordinate geometry we know that, the coordinates of point that divides the line joining (x₁, y₁), (x₂, y₂) in m:n, are;

[(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]

Plugging in the relevant values gives;

[(5 * 7 + 1 * 1)/(5 + 1)], [(5 * 2 + 1 * -10)/(5 + 1)]

⇒ (6, 0)

Therefore, the y-coordinate of the point that divides the directed line segment from J to K into a ratio of 5:1 is 0.

What are m∠1 and m∠2?

Answers

Answer:

B. <1 = 35, m<2 = 30

Step-by-step explanation:

To figure out m<1 I first need to figure out the other missing angle. A straight line is a 180 degree angle. Taking that information you can do 180 - 115. This means that the missing angle is 65 degrees. The interior angles of triangles always add up to 180.

80 + 65 = 145

180 - 145 = 35

<1 = 35

Repeat with the other side.

85 + 65 = 150

180 - 150 = 30

<2 = 30

how many degrees should the central angle of
the section that represents curry be?

Answers

Answer:

144°

Step-by-step explanation:

The central angle of a sector in a pie chart is proportional to the fraction the represented data is of the whole.

fraction

The total number of meals ordered at the restaurant was ...

11 +12 +7 = 30

The fraction of those that were Curry was ...

12/30 = 2/5

angle

Then the central angle of the sector representing Curry will be 2/5 of the circle, or ...

2/5 × 360° = 144°

The central angle of the section representing Curry will be 144°.

What is the solution for x in the equation?

-2x + 14 + 10x = 34

A.

B.

C.

D.

Answers

Answer: 2.5

Step-by-step explanation:

-2x + 14 + 10x = 34

8x + 14 = 34

8x = 34 - 14

8x = 20

x = 20/8

x = 5/2

x = 2.5

Combine the like terms first
14 +8x =34
Subtract 14 both sides
8x = 20
Divide both sides by 8
x = 20/8
Reduce
x= 5/2
x = 2 1/2 or 2.5

How to determine the mean?

The given parameters of the binomial distribution are given as:

n = 48 and p = 3/5

The mean is then calculated using:

μ = np

This gives

μ = 48 * 3/5

Evaluate

μ = 28,8

Hence, the mean of the binomial distribution is (d) μ = 28,8
