Solve the following equations:
a)
4b = 20

Answers

Answer:

b = 5

Step-by-step explanation:

You want to get b on one side alone so you divide by 4.

20 divided by 4 is 5.

Answer:

b = 5

Step-by-step explanation:

4b = 20

Whatever we do to one side of the equation, we have to do to the other.

To "isolate the variable", or get "b" by itself, we have to divide both sides by 4

4b divided by 4 is b, since "4b = 4 times b"

20 divided by 4 is 5

4b = 20

b = 5

The graph of the linear equation can be seen below.

Which graph represents the given function?

Here we have the linear function:

y = 5x + 3

To graph this, we need to find two points on the equation and then connect them with a line.

By evaluating in 0 we get:

y = 5*0 + 3 = 3

So the point (0, 3) is on the line.

By evaluating on 1 we get:

y = 5*1 + 3 = 8

So we have the point (1, 8).

Now we just plot them and connect them with a line, the graph is the one below.

Can someone help I don’t understand my answer are not adding up

Answers

Answer:

B

Step-by-step explanation:

∠ ABC = 9x + 5 ( alternate angles )

∠ ABC and ∠ DCB are sam- side interior angles and sum to 180° , that is

9x + 5 + 16x = 180

25x + 5 = 180 ( subtract 5 from both sides )

25x = 175 ( divide both sides by 25 )

x = 7

Then

∠ ABC = 9x + 5 = 9(7) + 5 = 63 + 5 = 68° → B

Step-by-step explanation:

Given A ladder leans against the side of a house

Given the angle of elevation of the ladder is 68° when the bottom of the ladder is 16 ft from the side of the house

Let 'C' be the point of observation.

Given CA= 16 ft

 From right angle triangle

     

     

     x = 16 × cos 68°

One early afternoon, Dennis' shadow is 11 inches long. If Dennis is 60 inches tall, the distance between the top of his head and the end of the shadow is ___ inches.

Answers

Answer: 61 inches

Explanation:

Let the distance between the top of his head to the end of the shadow be d.

Dennis is standing perpendicular to the shadow. So the triangle formed is a right triangle.

Using the Pythagoras Theorem,
d^2 = 11^2 + 60^2
d^2 = 121 + 3600
d^2 = 3721
d = sqrt(3721)
d = 61 inches

Answer:

61inches

Let the distance between the top of his head to the end of the shadow be d.

Dennis is standing perpendicular to the shadow. So the triangle formed is a right triangle.

Using the Pythagoras Theorem, d^2 = 11^2 + 60^2 d^2 = 121 + 3600 d^2 = 3721 d = sqrt(3721) d = 61 inches

Paul wants to buy a car. He needs to take out a loan for $7000. The car salesman offers him a loan with an interest rate of 8%, compounded annually. Paul considers two options to repay the loan.
Option 1: Pay $200 each month, until the loan is fully repaid
Option 2: Make 24 equal monthly payments.
a. Use option 1 to calculate
the number of months it will take for Paul to repay the loan.
b. Use option 1 to calculate the total amount that Paul has to pay.
c. Use option 2 to calculate the amount Paul pays each month.
d. Use option 2 to calculate the total amount that Paul has to pay.
e. Give a reason why Paul might choose option 1.
f. Give a reason why Paul might choose option 2.

Answers

Answer:

a. It will take approximately 40 months

b. The total amount Paul has to pay is approximately $8,000

c. The amount Paul pays each month is approximately $316.59

d. The amount Paul has to pay is approximately $7,598.16

e. Lower monthly payment

f. Lower total payment amount (amount to be paid)

Step-by-step explanation:

a. The loan amount, PV = $7,000

The annual interest rate, r = 8%

Option 1; The amount of equal monthly payment to repay the loan = $200

Option 2; The number of equal monthly payment to repay the loan = 24

The formula for the present value of an annuity is given as follows;

[tex]PMT = \dfrac{\dfrac{r}{12} \times PV}{1 - \left (1 + \dfrac{r}{12} \right)^{-n}}[/tex]

Where;

PMT = The monthly payment

n = The number of months

Where PMT = $200, we have;

[tex]200 = \dfrac{\dfrac{0.08}{12} \times 7,000}{1 - \left (1 + \dfrac{0.08}{12} \right)^{-n}}[/tex]

[tex]1 - \dfrac{\dfrac{0.08}{12} \times 7,000}{200} = \left (1 + \dfrac{0.08}{12} \right)^{-n}[/tex]

[tex]1 - \dfrac{7}{30} = \dfrac{23}{30} = \left ( \dfrac{151}{150} \right)^{-n}[/tex]

[tex]-n = \dfrac{ ln \left(\dfrac{23}{30} \right)}{ln\left(\dfrac{151}{150} \right) } \approx -39.988[/tex]

∴ The number of months it will take for Paul to repay the loan, n ≈ 39.988 ≈ 40 months

b. The total amount Paul has to pay, A = PMT × n

Therefore, b plugging in the values of PMT, and 'n', we get;

A ≈ $200 × 40 = $8,000

c. Using option 2, we have;

n = 24

Therefore;

[tex]PMT = \dfrac{\dfrac{0.08}{12} \times 7,000}{1 - \left (1 + \dfrac{0.08}{12} \right)^{-24}} \approx 316.59[/tex]

The monthly payment, PMT ≈ $316.59

d. The total amount Paul has to pay using option 2, A ≈ 316.59 × 24 = 7,598.16

The total amount Paul has to pay using option 2, A ≈ $7,598.16

e. A reason why Paul might choose option 1 is that option 1 offers lower monthly payment

f. A reason why Paul may choose option 2 is that option 2 offers a lower total amount that he has to pay.

A) It will take 48 months for Paul to repay the loan.

B) Paul will have to pay $ 9,523.42.  

C) Paul should pay $ 340.20 per month.

D) Paul will have to pay $ 8164.80.

E) Paul might choose option 1 because his monthly payments would be lower and, therefore, more accessible.

F) Paul might choose option 2 because his total payout would be much less than option 1.

Since Paul wants to buy a car, and he needs to take out a loan for $ 7000, and the car salesman offers him a loan with an interest rate of 8%, compounded annually, and Paul considers two options to repay the loan (Option 1: Pay $ 200 each month, until the loan is fully repaid, and Option 2: Make 24 equal monthly payments), for:

A) Use option 1 to calculate the number of months it will take for Paul to repay the loan. B) Use option 1 to calculate the total amount that Paul has to pay. C) Use option 2 to calculate the amount Paul pays each month. D) Use option 2 to calculate the total amount that Paul has to pay. E) Give a reason why Paul might choose option 1. F) Give a reason why Paul might choose option 2.

The following calculations must be performed:

A) 7000 x 1.08 ^ 4 = 9,523.42

200 x 12 x 4 = 9600

Therefore, it will take 48 months for Paul to repay the loan.

B) Paul will have to pay $ 9,523.42.

C) 7000 x 1.08 ^ 2 = 8,164.80

8,164.80 / 24 = 340.20

Therefore, Paul should pay $ 340.20 per month.

D) Paul will have to pay $ 8164.80.

E) Paul might choose option 1 because his monthly payments would be lower and, therefore, more accessible.

F) Paul might choose option 2 because his total payout would be much less than option 1.

Answers

f + 6 = ?

Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.

For example, if f was 5, this is what the equation would look like:

5 + 6 = 11

If f was -3, this is what the equation would look like:

-3 + 6 = 3

So, again, the answer can be anything. It depends on what f is.

Answers

Answer:

Step-by-step explanation:

27 + D + 2A + C = 25 + D + B + C + A

subtract D, A, C on both sides

=> 27 + A = 25 + B

=> B = A + 2

3D + A + 29 = 2B + D + A + 27

=> 2D + 29 = 2B + 27

=> 2D = 2B + 27 - 29

=> D = B - 1

substitute:

27 + (B - 1) + 2(A + 2) + A = 2A + B + 30

substitute again:

2A + (A + 2) + 30 = 3A + 32

The time, T (seconds) it takes for a pot of water to boil is inversely proportional to the cooker setting, H ,applied to the pot.
When H=6 T=90.
What must the cooker setting be if it takes 5 minutes to boil the water?

Answers

Answer:

[tex]1.8[/tex]

Step-by-step explanation:

Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:

[tex]T\propto \frac{1}{H}[/tex]

Convert 5 minutes to seconds:

[tex]5\cdot 60=300\:\mathrm{s}[/tex]

Therefore, from the initial data given (When H=6, T=90), the new time is [tex]\frac{300}{90}=3\frac{1}{3}[/tex] larger. Therefore, H must be [tex]3\frac{1}{3}[/tex] times smaller for them to be inversely proportional.

[tex]H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}[/tex]
