Answer:

$10,213.34

Step-by-step explanation:

Using the compound interest formula;

A = P(1+r/n)^t

Given that;

P = $7,200

rate r = 6% = 0.06

Time t = 6years

n = 1

Substitute into the formula

A = 7200(1+0.06)^6

A = 7200(1.06)^6

A = 7200(1.4185)

A = 10,213.34

Hence the final amount is $10,213.34

Answer:

x=9

Step-by-step explanation:

The sum of all three angles inside a triangle is always 180 and the small square in the bottom left corner means that that is a 90 degree angle.

90+5x+5x=180

add the x values together

90+10x=180

subtract 90 from both sides

10x=90

divide both sides by 10

x=9

Answer:

b. A horizontal line with no "rise" and infinite "run"

Step-by-step explanation:

since y = 7, y will always equal 7 no matter what the x value is, so it has no rise, or increase in y value. But it doesn't say anything about the x value, so it infinitely increases. The answer is b. A horizontal line with no "rise" and infinite "run"

Answer:

The scientist must use 10 ounces of Solution A and 40 ounces of Solution B.

Step-by-step explanation:

Since a scientist has two solutions, which she has labeled Solution A and Solution B, each containing salt, and she knows that Solution A is 40% salt and Solution B is 90% salt, and she wants to obtain 50 ounces of a mixture that is 80% salt, to determine how many ounces of each solution should she use the following calculation must be performed:

100 x 0.9 + 0 x 0.4 = 90

90 x 0.9 + 10 x 0.4 = 85

80 x 0.9 + 20 x 0.4 = 80

50 x 0.8 = 40

Therefore, the scientist must use 10 ounces of Solution A and 40 ounces of Solution B.

Answer:

2400

Step-by-step explanation:

because it goes down 400 each year

Karen expects the vehicle to depreciate by 600 each year.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Now, It is expected to depreciate from 4000 to 400 in 6 years.

Hence, The depreciation per year is the ratio is,

⇒ Depreciation per year = (Total depreciation) / (Number of years)

Hence, The total depreciation is the change in value, so the depreciation per year is

⇒ (4000 - 400)/6

= 3600 / 6

= 600

Thus, Karen expects the vehicle to depreciate by 600 each year.

To solve all of the problems in Question 8 I had to move all of the terms without an (x) to the right side. After I did this I divided everything by the number attached to the (x) to find the value of (x) by itself.

Answer and Step-by-step explanation:

8a.

3x + 6 = 27

Subtract 6 from both sides.

3x = 21

Divide 3 from both sides.

x = 7

8b.

6x + 3 = 27

Subtract 3 from both sides.

6x = 24

Divide 6 from both sides.

x = 4

8c.

27x + 3 = 6

Subtract 3 from both sides.

27x = 3

Divide 27 from both sides.

x = 3/27

Answer:

B

Step-by-step explanation:

First we find out over how many years the growth happened, from 1985 to 2020, that's 35 years.

In 1985 the club had 23,000 members, and it grew at an ave. rate of 5% each year. So, to find out 5% of 23,000 we can divide it by 100 to find 1% and then multiply by 5.

23,000 / 100 = 230 now 230 times 5 is 1150, to check our work we can multiply 1150 by 20 because it is 5% to get 100% and it is 23000 so we are on track so far. Now over the span of 35 the club grew by 1,150 each year, so, 1150 times 35 is 40,250 and if we add that to 23,000 we get 63,250. Round to the nearest thousand which would be

Answer:

Gordon will have $ 34,178 after 8 years of investment.

Step-by-step explanation:

Given that Gordon invested $ 28,000 into a CD compounded quarterly with an annual interest rate of 2.50%, to determine how much money Gordon would have after 8 years, the following calculation must be performed:

28,000 x (1 + 0.025 / 4) ^ 8x4 = X

28,000 x (1 + 0.00625) ^ 32 = X

28,000 x 1.00625 ^ 32 = X

28,000 x 1,220 = X

34,177.997 = X

Therefore, Gordon will have $ 34,178 after 8 years of investment.

Gordon will have 3,417,799 cents in his account after 8 years

The formula for calculating the compounding amount is expressed as;

[tex]A =P(1+\frac{r}{n} )^{nt}[/tex] where:

P is the amount invested

r is the rate in decimal

t is the time taken

n is the compounding time

Given the following

P = $28,000

r = 2.50% = 0.025

t = 8 years

n = 4

Substitute the given parameters into the formula to have;

[tex]A =28,000(1+\frac{0.025}{4} )^{4(8)}\\A=28,000(1+0.00625)^{32}\\A=28,000(1.00625)^{32}\\A=28,000(1.2206)\\A=$34,177.99[/tex]

Hence Gordon will have 3,417,799 cents in his account after 8 years
