7.2x = -14.4

Step 2: Divide both sides by 7.2

x = -2

Step 3: Check

Plug in x to verify it's a solution.

7.2(-2) = -14.4

A cone-shaped tent has a diameter of 12 ft and a height of 6 ft.What is the approximate volume of the tent?
Use 3.14 to approximate pi, and express your final answer to the nearest tenth.
______ft3

Answers

Here's the formula for the volume of a cone:

V=(1)/(3)\pi\ r^2h

Plug in 3.14 for \pi.
Plug in 6 for the height h.
Our radius is half of our diameter. r=6.

V\approx\frac13*3.14*6^2*6

6² = 6 × 6 = 36.
Now we just multiply together 1/3, 3.14, 36, and 6 to get...

V\approx226.08

Rounding to the nearest tenth...

\boxed{V\approx226.1\ ft^3}
Cone formula: 1/3(\pi r^(2) h)
     
Step 1(Fill in formula): 1/3((3.14)(6^(2))(6))
Step 2 (Solve): 1/3((3.14)(36)(6))
Step 3 (Solve): 1/3(678.24)
Step 4 (Complete) : 226.08ft³

This formula says that the bank will TAKE three percent of the money
in your account whenever the account is inactive for a year.  Nice bank !
Personally, I'd get ALL of my money out of that bank ASAP, and run,
don't walk, to a different bank.

Anyway, the equation is  y = 7500(0.97)^x .
They want to know the y-intercept.
Just like the graph of ANY equation, the y-intercept is the place
where the graph is on the y-axis ... the place where x=0 .
What's the value of 'y' in this equation when x=0 ?
What's the value of  (0.97)⁰  ?
Do you remember that ANY number raised to the zero power is ' 1 ' ?
(0.97)⁰ = 1
So, when x=0,  y = 7500.

What does that mean ?
Well, the question tells you that 'y' is the value of an account "that was
left inactive for a period of 'x' years".
So x=0 at the beginning, when the money is first deposited, and
the account hasn't been inactive for ANY period yet.

When x=0, y=7500.  The y-intercept is the amount of money that
the person originally deposited in the account.  If he leaves the
account inactive, then the bank will multiply it by  0.97  each year ...
the same as reaching in and grabbing 3% of the money in the account !

isabella spends $4.87 on paintbrushes and paint. How many of each item does she buy? The paintbrushes cost $0.95 and the jar of paint cost $.099 each.

Answers

Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87. Answer: Isabella buys 2 paintbrushes and 3 jars of paint.

The soccer field measures 80 meters by 120 meters. Which is the correct unit of measurement to figure out how much fertilizer is needed to cover the field?

Answers

To find out the area of the field, you just need to multiply 80 meters by 120 meters.

80 meters * 120 meters = 9600 meters²

Therefore, the unit of measurement to figure out how much fertilizer is needed to cover the field is meters².
