Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

Step-by-step explanation:

Commutative propriety really means you can change (commute) the order you add or multiply numbers and the result will be the same

ab = ba

x+18 = 18+ x

Associative propriety means you can add in any order

3+(a+b) = (3+a) + b

Combine like terms is 8 of something - 3 of the same thing is 5 of something

8x^4  - 3x^4 = 5x^4

only the terms with b are the same kind

9b+ 4b -14 = 13b -14

Step-by-step explanation:

after adding to the total with the markers, lunchbox and shirts you get $15.75  then multiply the normal price $15.75 by 20 then divide it by one hundred and you will get $3.15 as your saved amount and you will then do 15.75-3.15= 12.6 make sure to put a 0 after the 6 making it 60.

(2.50+5.25+7.99= $15.75)

(15.75-3.15= 12.60)

Answer:

Step-by-step explanation:

38.13 inch² (Approximately)

The following figure has a Semicircle and a Rectangle.

The length of the Rectangle = 6 inches

The breadth of the Rectangle = 4 inches

Area of a Rectangle = Length * Breadth

                                   = 6 * 4

                                   = 24 inch²

Diameter of the Semicircle = 6 inches

Radius of the Semicircle = Diameter/2

                                          = 6/2

                                          = 3 inches

Area of a Semicircle = πr²/2

                                   = 3.14 * 3²/2

                                   = 3.14 * 3 * 3/2

                                   = 3.14 * 9/2

                                   = 1.57 * 9

                                   = 14.13 inch² (Approximately)

Total area of the figure = Area of the rectangle + Area of the Semicircle

                                        = 24 + 14.13

                                        = 38.13 inch² (Approximately)

The probability of choosing a green shirt is 20%=1/5=.2

Step-by-step explanation:

find the total amount = 10

Find the total of question (probability of choosing green) = 2

set as a fraction:

Numerator = amount needed (2)

Denominator = all things/objects involved (10)

PS*

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

ex:

10/2=5=500% (this can't be the answer)

So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

Answer:

A common mistake that students make when they cross-multiply is that they forget about the equals sign and write the two parts as a new fraction. Make sure to always put the equals sign in between the two cross-products. If you're solving an equation and your equals sign has disappeared, you have a problem!

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer: Mia is 13 years, 4 months and 7 days old

Explanation:

60 minutes in an hour

24 hours in a day (60 x 24 = 1440 minutes)

30 days in a mouth (1440 x 30 = 43,200 minutes)

360 days in a year (1440 x 365 = 525,600 minutes)

To find out how many years old she is we must divide the number of minutes old she is by the number of minutes in a year.

7015680 / 525,600 = 13 years with a remainder of 182,880 minutes

To find out how many months old she is we must divide the remaining minutes by the number of minutes in a month.

182,880 / 43,200  = 4 months with a remainder of 10,080 minutes

To find out how many days old she is we must divide the remaining minutes by the number of minutes in a day.

10,080 / 1440 = 7 days

Answer:Under↓↓↓

Step-by-step explanation:

-x=3x-4 (substitute -x for y)

-4x=-4 (Subtract 3x from both sides)

x=1 (Divide both sides by -4)

Since y=x then y=1

Answer:

X=1

Step-by-step explanation:

So if you look at the two y= equations, you'll see that you can make them equal two one another because they both equal y

Placing the -x in place of y for it to look like this; -x = 3x-4. Subtract the 3x to the other side to get -4x =-4. Then divide the 4 from the x to isolate it and you get x=1!

Option D 78.5

Step-by-step explanation:

Circumference= 2*Pi*r

                        = 2 * 3.14 * 12.5

                        = 78.5

The circumference of the circular car tire is 78.5 inches.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

Given that,

Radius of a circular car tire = 12.5 inches

We have to find the circumference.

The given car tire is circular in shape.

The formula to find the circumference of a circular shape is,

Circumference = 2πr, where r is the radius of the circle.

Substituting the given value of r,

Circumference = 2π × 12.5

                         = 25π

Given to use 3.14 for π.

Circumference = 25 × 3.14 = 78.5 inches.

Hence the required circumference of the circular car tire is 78.5 inches.
