Stephen invests in an account that pays 3% compound interest annually. He invests $5,500. He uses the expression P(1+r)t to find the total value of the account. What will be the total value of the account after 6 years?
Answer:
A = $6567.29
Step-by-step explanation:
A = P(1+r)^t
Where A = amount in account
P = principal
r = interest rate in decimal form
t= time
We know that P =5500
r = .03
t =6
Substitute these values into the equation.
A = 5500(1+.03)^6
A = 5500(1.03)^6
A = 5500(1.194052297)
A=6567.287631
Since this is money we round to the nearest cent
A = $6567.29

Frosty has traveled 2/3 of the way down Santa Claus lane.The lane is 336 feet long.How many feet has Frosty traveled?
We can multiply 336 by 2/3 to find out.
2/3(336)
To make this easier, we can change 336 to 336/1, which does not change it's value.
Multiply 336 by 2.
336 * 2 = 672
Multiply 1 by 3.
1 * 3 = 3
Our new value is 672/3
Evaluate, divide both sides of the fraction by 3.
672/3 = 224.
3/3 = 1
224/1
224/1 = 224
Frosty has traveled 224 feet.john is 5 3/4 ft tall how tall is john in inches
John's height from feet to inches is a total of 69 inches.
The question asks how tall John is in inches if he is 5 3/4 feet tall.
To convert feet to inches, you use the fact that one foot equals 12 inches. You need to multiply the whole number of feet by 12 and then add the inches that result from the fractional part.
Step 1: Convert the whole number of feet to inches. John is 5 feet tall, and each foot is 12 inches:
5 feet x 12 inches/foot
= 60 inches
Step 2: Convert 3/4 of a foot to inches. Since there are 12 inches in one foot, you calculate 3/4 of 12:
3/4 x 12 inches
= 9 inches
Step 3: Add the number of inches from the whole feet and the fractional foot together to get John's height in inches:
60 inches + 9 inches = 69 inches
John is 69 inches tall.

Which graph represents the solutions to the inequality 2x-6<4?
Answer:
D
Step-by-step explanation:
solving the inequality
Inequalities of the type | x | < a always have a solution of the form
- a < x < a
For | 2x - 6 | < 4 then solution is
- 4 < 2x - 6 < 4 ( add 6 to all 3 intervals )
2 < 2x < 10 ( divide all 3 intervals by 2 )
1 < x < 5 → graph D
The open circles at the ends of the blue line indicate up to but not including these points.
[tex]|2x-6| < 4\iff2x-6<4\ \wedge\ 2x-6>-4\qquad\text{add 6 to both sides}\\\\2x<10\ \wedge\ 2x>2\qquad\text{divide both sides by 2}\\\\\boxed{x<5\ \wedge\ x>1}\to1< x<5[/tex]

Answer: 4th graph.In a survey, a group of students were asked to name their favorite day of the week. There were 8 students who chose “other”. How many students participated?
Answer:
Step-by-step explanation:I would say 56 or 63. My reason is because when it says pick their favorite day of the week. It is 7 days a week so that gives me right there that I have to multiply. Then there is an option of "other" so I would probably multiply it by 8 to get the number of people who participated. Hope this helps☺

Emma went to a salon to get her hair cut. The price of the haircut is $65. She wants to leave a 20% tip. What is the total amount she should pay?
Answer:
She should leave a total of $78.
Step-by-step explanation:
To find this, we first need to find the tip amount. We can do this by multiplying the total by the tip percentage.
$65 * 20% = $13
Now that we have that, we need to add it to the cost.
$65 + $13 = $78
The value of a machine depreciates each year by 3 %. What will be the value of the machine bought for Rs 1,00,000 after two years.
Answer:
1,000,000 / 1.03 = 970,873.79 After 1st Year
970,873.79 / 1.03 = 942,595.91 After 2nd Year
Step-by-step explanation:
Answer:
Two thirds rounded would be 66.67%. I’m uncertain whether you were asking about a straight line depreciation or some sort of degressive depreciation.
Basically, in a straight-line depreciation, you would calculate each depreciation as a fraction of your asset’s original value. A machine worth $1000 in year 0 would depreciate annually with a constant amount of $100.
Your machine would be worth less than 66.67% of its original value after at least 4 years (4 x 10%). More precisely, 3 years and (33.3% x 365 days) 122 days.
Applying a degressive depreciation method, you would calculate the depreciation in each year as a fraction of your asset’s residual value. This implies your depreciations would decrease each year (hence “degressive”). As soon as your depreciations fall below the amount you would depreciate in a straight line depreciation, you switch to the latter. The reason for this is that it does not really make sense for a company to depreciate it’s assets with a lesser amount, given the tax benefits of depreciations and the time value of money.
Assuming the duration of the asset’s useful life is 10 years, you would switch to the straight-line depreciations after the first year. This scenario would be equal to the straight-line depreciation: 3 years and 122 days.
In case the duration of the asset’s useful life is shorter or longer than 10 years, the amount of time required for the asset to have less than two-thirds of its initial value depends on the duration of is life.
so basically the answer is
1,000,000 / 1.03 = 970,873.79 After 1st Year
970,873.79 / 1.03 = 942,595.91 After 2nd Year

Answer:
Relationship between distance and time in simplified form as a unit rate is; [tex]\frac{47}{1}[/tex]
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1, such as 5 feet per second or 3 miles per hour, they are called unit rates.
Unit rate = [tex]\frac{distance}{time}[/tex]
From the given table:
Take any

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00. Write a function to represent this scenario.

Above the solid line
Below the solid line
Above the dashed line
Below the dashed line
Answer:
Below the solid line.
Step-by-step explanation:
When you solve for y, you will have a less than or equal to sign, so the shading is below the line.
Answer:
Below the solid line
Step-by-step explanation:
−4y − x ≥ 7
We need to solve for y
Add x to each side
−4y − x +x≥ 7+x
-4y ≥ 7+x
Divide each side by -4. Remember to flip the inequality
−4y/-4 ≤ (7+x)/-4
y ≤ -1/4 x - 7/4
Y is less than or equal to the value so the line is solid (equals sign)
and below ( less than)
