What's the simple interest of $7200 for 3months at 7% per annum

MakcuM [25]

Answer:

The interest is $1512 and the amount is $1519.

Step-by-step explanation:

: Convert interest rate of 7200% per month into a rate per year. Then Convert 3 months into years. Next Find an interest by using the formula, where I interest, P is total principal, i is the rate of interest per year, and t is the total time in years. Lastly, Find an amount by using the formula.

BRAINLIEST TO WHOEVER IS CORRECT!!!

Answer:

y= $-\frac{4}{3}$ x+2

Step-by-step explanation:

To write the equation for this line, we are going to use slope-intercept form, which is written as

y=mx+b.

Here are the meanings of each variable:

y= basically the "name" of the function and it always stays as y.

m= slope, which is rise over run.

x= variable that is always on the right of the slope and it always stays as x.

b= y-intercept, or the value that crosses the y-axis.

We will substitute numbers into the equation along the way. The first thing we will want to do is find b, which is the easiest.

The line crosses the y-axis at 2, so that is our value of b.

Our new equation is

y=mx+2.

Next, we will find the slope. The most efficient way of doing this is looking at the lowest point that is already provided, (3, -2), and finding a way to rise and run to the highest point, (0, 2).

If you look closely at the graph, we need to rise up 4 and run over -3 to get to the other point. Therefore, the slope is $-\frac{4}{3}$ , and we can substitute it into our equation, which is completed and is now

y= $-\frac{4}{3}$ x+2

I hope this helps you out!! Have an awesome day ^^

Drag steps of the solution into order to solve for x in the equation 6(x–5)=54.

Zanzabum

Alright first things first you need to distrubute 6(x-5) so that will be 6x-30=54
In order for you to get x by itself you need to add -30 on both sides so that'll be your second step is to add -30 on both sides: -30+-30 54+-30. Cancel out -30 and add the 54 and -30 together and you'll get 24.
Third and final step you have 6x=24 but you aren't done yet. You need to get X by it self so divide 6 on both sides. Cancel out the x and now you have x by itself. Divide 24 and 6 and you'll get 4

So your answer will be x=4.

Hope this helped :)
have a great day

A fence must be built to enclose a rectangular area of 20 comma 000 ftsquared. fencing material costs $ 2 per foot for the two s

Maslowich

The first thing we should do is write the functions.
For the area we have:
A = w * h = 20000 feet ^ 2
The price is:
Cost = (4 * 2 * h + 2 * 2 * w)
Substitute for h ::
C (w) = (4 * 2 * (20,000 / w) + 2 * 2w)
Rewrite we have:
C (w) = 160,000 / w + 4w
Take the derivative:
C '(w) = 160000 (-1 / w ^ 2) + 4
We equal zero and clear w:
0 = 160000 (-1 / w ^ 2) + 4
160000 / w ^ 2 = 4
w ^ 2 = 40000
w = 200 (approximately)
width = 200 ft; so cost is 2 * ($ 4) 200 = $ 1600
height = 20000/200 = 100 ft; so cost is 2 ($ 2) 100 = $ 400
Total cost = $ 2000
Answer:
The cost of the least expensive fence is:
Total cost = $ 2000
