Answer:

1

Step-by-step explanation:

The slope of the perpendicular is the negative inverse of the slope of the line.

m = -1 / (-⅓)

m = 3

The slope between the two points is 3, so:

3 = (15 − 6) / (4 − n)

3 (4 − n) = 9

4 − n = 3

n = 1

3/4+5/6 divided by 2/3 in simplest form show work, please!<br> Thanks!
Nuetrik [128]

Answer:

2 \frac{3}{8}

Step-by-step explanation:

3/4 + 5/6  (lowest common denominator = 12)

= 9/12 + 10/12

= 19/12

19/12 ÷ 2/3  (reciprocate 2/3 to replace division sign by multiplication sign)

= 19/12 x 3/2

= 57/24

= 19/8

= 2 \frac{3}{8}

Hope this helps :)

Meryl needs to add enough water to 11 gallons of an 18% detergent solution to make
saveliy_v [14]
The percentage here must be assumed as by volume. Therefore, it means that the solution has 0.18 gallons of detergent / gallon of solution. If Meryl needs to add 11 gallons of water then she has 2.41 gallons of detergent. Calculation is as follows:

.18 = x / x+4

Solving for x, we obtain

x = 2.41

You have been told that you need $21,600 today in order to have $100,000 when you retire 42 years from now. what rate of interes
Savatey [412]
You will have to use this formula:
<span>log(1 + rate) = {log(total) -log(Principal)} ÷ Years
</span>log(1 + rate) = {log(100,000) -log(21,600)} <span>÷ </span><span>Years
</span>log(1 + rate) = { 5 -4.3344537512} / Years
log(1 + rate) = <span> <span> <span> { 0.6655462488} / 42
</span></span></span>log(1 + rate) = <span> <span> <span> 0.0158463393 </span> </span> </span>
1 + rate = 10^<span> <span> 0.015846339
</span></span><span>1 + rate = </span>1.0371613856
rate = .0371613856<span>
rate = </span><span>3.71613856%

</span>************************************************************************
Double-Check
Total = principal * (1 +rate)^years
Total = 21,600 * (<span>1.0371613856)^42
</span> <span>Total = 21,600 * </span> <span> <span> <span> 4.6296296291 </span> </span> </span> <span><span> </span> </span> 
Total = 100,000

Correct !!
