14 year it would take to earn $1000 simple interest on an investment of $800 at 9% annual interest.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Let the number of years be represented as T
Now , the equation will be
The simple interest I = $ 1000
The rate of interest R = 9 %
The principal amount P = $ 800
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
1000 = ( 800 x 9 x T ) / 100
On simplifying the equation , we get
72T = 1000
Divide by 72 on both sides of the equation , we get
T = 13.89 years
Therefore , the number of years is approximated to 14 years

A rental car company charges $33.73 per day to rent a car and $0.06 for every mile
driven. Elizabeth wants to rent a car, knowing that:
She plans to drive 450 miles.
• She has at most $430 to spend.
•
Which inequality can be used to determine x, the maximum number of days
Elizabeth can afford to rent for while staying within her budget?
Answer:
430 > 33.73x + 27 ----> x < 11
Step-by-step explanation:
The inequality describes the total amount that can be spent for a whole number of days. To solve for the number of days, solve for x (x<11.95). Because she can't rent for only a part of a day, and because she can't spend more than $430, the inequality becomes x<11.
Answer:
Step-by-step explanation:
33.73x + 27 <= 430
0.06 is for every mile. She plans to drive 450 miles. So 0.06 times 450. Which is 27.
Then your have the 33.73 for each day for the rent of the car. We don't know how many days so we'll just put x.

4x-y=10 and y=2x-2 answers
Answer:
y = 6
x = 4
How to find 'x':
4x - y = 10
y = 2x - 2
First, you need to substitute the 'y' into the first equation.
4x - 2x - 2 = 10
Next, add the x's together. As it's a negative 2x then take away 2 from 4.
2x - 2 = 10
3. Now that it's a normal equation, you can add 2 to cancel out the -2
2x = 8
4. Then divide the 8 by 2 and you will get the answer to x which is 4
x = 4
How to find 'y':
1. Now that we have found out 'x'. Let's go back to y = 2x -2 and use the x to found the answer out. It should be something like this:
y = 2x - 2
y = 2(4) - 2
y = 8 - 2
8 - 2 = 6
y = 6
Conclusion:
So the answer would be:
y = 6
x = 4
You can see if it's correct by putting y into 4x - y = 10.:
4x - 2 = 10
4(4) - 6 = 10
16 - 6 = 10
So that means that y and x are the correct answer.

Answer:
w = 38% or 37%
w = 37.7162629758% exact
Step-by-step explanation:
Lets say c = 100
If k = 15, 100 is decreases by 15% 2 times.
15% of 100 = 15
100 - 15 = 85
d = 85
Now lets find a
85 times .85 = 72.25
Now find what percent of 72.25 you have to add to itself to get 100
100 - 72.25 = 27.75
27.75 divided by 72.25
37% rounded

Answer:
N=3
Step-by-step explanation:
use cross multiplication to find 28N=84 and then divide both sides by 28 to get N=3
Answer:
N = 3
Step-by-step explanation:
Given Δ ABC is similar to Δ DEF , then the ratios of corresponding sides are in proportion, that is
[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{21}{N}[/tex] = [tex]\frac{28}{4}[/tex] = 7 ( multiply both sides by N to clear the fraction )
21 = 7N ( divide both sides by 7 )
3 = N
Determine the intercepts of the line.
Answer:
y-intercept: (0, 5/2)
x-intercept: (5/3, 0)
Step-by-step explanation:
The y-intercept is found by setting x=0 and dividing by the coefficient of y.
0 +2y = 5
y = 5/2
The x-intercept is found by setting y=0 and dividing by the coefficient of x.
3x +0 = 5
x = 5/3
The intercepts are ...
y-intercept: (0, 5/2)
x-intercept: (5/3, 0)

The given relation is not a function.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given a table of x and y values.
We have to determine the relation is a function or not.
By the definition of functions, a relation is a function if an input value does not map to two output values.
That is, an x value will not map to two y values.
From the table,
x = 1 maps to two y values -2 and -3.
This is not possible for functions.
So this is not a function.
Hence the relation is not a function.

Sarah works for 8 minutes and for every 8 minutes she gains 23 coins everytime she works and she is saving for 2,000 coins in total. How many hours will it take Sarah to get 2,000 coins?
Answer:
11.59 hours {Basically 12 hours]
Step-by-step explanation:
Sarah's coin rate is 23 coins/8 minutes, or 2.875 coins/minute
Rate * Time(X) = Coins
(2.875 coins/min)*(X) = 2000 coins
X = (2000 coins)/(2.875 coins/min)
X = 695.65 minutes
(695.65 minutes)*(1 hour/60minutes) = 11.59 hours

Find the solution of the system of equations.
2x-3y=-14
5x+9y=-2
Answer:
Well to solve this I’m gonna use substitution
So
2x-3y=-14
5x+9y=14
I‘m gonna isolate ”x” on the first equation
So it’ll be
2x-3y=-14
2x=-14+3y
x=-7+1.5y
X is -7+1.5y
Now you can subsitute into other equations to find what Y is worth
So lets use the second equation
5(-1+1.5y) + 9y = 14
Now solve for y which is -2
If you subsitute Y back in an equation you’d get -4 for x
So y = -2
and X= -4
When the swimming pool is 25% full, it takes 2250 cubic meters (m3) to fill it up from that point. When it is full, it can be emptied at a rate of 120 m3/h. How many hours does it take to empty an 80% full pool?
Answer:
20 hours
Step-by-step explanation:
The volume of water when the pool is 80% full can be found using the proportion ...
2250/75% = v/80%
v = (80/75)(2250) = 2400 . . . cubic meters
Emptying at the rate of 120 m³/h will take ...
time = volume/rate
time = (2400 m³)/(120 m³/h) = 20 h
It will take 20 hours to empty the pool from 80% full.
