When given a rate of 8% and a time of 2 years and an interest earned of $108, what is the principal and the new balance?
Lerok [7]

Answer:

Principal Value = $93.103

New Balance = $201.103

Step-by-step explanation:

Given:

Rate=R = 8%

Time =t= 2 years

Money earned = $108

To Find:

Principal interest = ?

New balance = ?

Solution:

The formula for Interest is

A = P(1+rt)

here A = $108, r= R/100 = 8/100 and t= 2

To Find

P=?

Now we have all values putting them in the formula we get

108 = P(1+\frac{8}{100}*2)

108=P(1+\frac{8}{50})

taking LCM and solving

108=P(\frac{50+8}{50})

108=P(\frac{58}{50})

Multiplying both sides by \frac{50}{58} we get

108*\frac{50}{58}=P(\frac{58}{50}*\frac{50}{58})

we will get

P=108*\frac{50}{58}

P=\frac{5400}{58}

We get

P = $93.103

so Principal Value is $93.103

Now

New balance = Principal value + Interest earned

                      = 93.103 + 108

                      = $201.103

New Balance = $201.103

To find the coordinates of point L, the midpoint of JK, the equation M = [5+1 over 2, 3-7 over 2] can be used. What are the coor
GaryK [48]
Since we are already given with the formula to solve for the coordinates of point L, all we have to do is to perform the necessary operation in the item. The formula for the coordinates of the midpoint is,
                    M = ((5 + 1) / 2 , (3 - 7) / 2)
performing the operation,
                   M = (3, -2)
Thus, the coordinates of point L are (3,-2).

Write an equivalent expression for 1/y -3/4
IgorLugansk [536]
We have the expression . To write a equivalent expression, we are going to rewrite the denominator of our expression using its common denominator 4:
Now, notice that we are basically diving 1 by , so we have a division involving fractions, and remember that to divide fractions, we just need to invert the second fraction and multiply:

We can conclude that the equivalent expression of  is .

Rewrite the equation from slow point form to slope intercept form<br> Equation: y-4=2(x+1)
Shkiper50 [21]

Answer:

y = 2x+6

Step-by-step explanation:

y-4=2(x+1)

Distribute

y-4 =2x +2

Add 2 to each side

y-4+4 = 2x+2+4

y = 2x+6

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept
