Answer:
The amount of money invested at 15% = 30,000
The amount of money invested at 5% = 30,000
Step-by-step explanation:
Calculation for How much money should be invested
Let x dollars = 15%,
Let y dollars= 5%,
x + y = 60,000
0.15x + 0.05y = 6,000
Multiply the 1st Equation by -0.15:
-0.15x - 0.15y = -9,000
0.15x + 0.05y = 6,000
Add the 2 Equations :
-0.1y = -3,000
y=3,000/0.1
y = 30,000
Substitute 30,000 for y in the 1st Equation
x + 30,000 = 60,000
x = 60,000 - 30,000
x= 30,000
PROOF:
.15*30,000+.05*30,000=6,000
4,500+1,500=6,000
6,000=6,000
Hence,
The amount of money invested at 15% = 30,000
The amount of money invested at 5% = 30,000
How many solution does 8(3x-6=6(x+8) have
Answer:
Step-by-step explanation:
at most 1.
8(3x - 6) = 6(x + 8)
24x - 48 = 4x + 48 Subtract 4x
24x - 4x - 48 = 4x -4x + 48 Combine
20x - 48 = 48 Add 48 to both sides.
20x = 96 divide by 20
x = 96/20
x = 4.8

Determine whether the given relations are functions.
Answer:
Yes, this relation is a function.
Step-by-step explanation:
It is a function because every input (left side) only has one output (right side). It doesn't matter if an output has multiple inputs. As long as an input has only one output, it is a function
Ex: 3 = 8 & 7 NOT an input
4 & 3 = 8 AN input
Lamark goes to a bowling alley to test his belief that rolling a bowling ball slowly will result in knocking down more pins. He gently rolls his bowling ball towards the bowling pins lined up at the end of the lane. The bowling ball stops in the middle of the lane without striking the pins. Which statement below best explains what happened?
Answer: Ball's kinetic energy became potential energy
Step-by-step explanation:
There are no options attached but this should be along the lines of what happened.
Kinetic energy refers to energy that an object has as a result of it moving whilst potential energy is the opposite and is energy that an object stores within itself due to several factors whilst it is not in motion.
The ball was initially in motion which means that it had kinetic energy but as the ball was slowing down, this energy was gradually converted to potential energy until the balls came to a standstill.

HELPPPP PLZZZ ASAPPP!!!Look at the illustration of four letters from the American Manual Alphabet. Decide whether the description of the letter is a good definition. If not,
choose a counterexample.
The letter I is formed by sticking up the smallest finger and folding all the other fingers into the palm of your hand with the thumb folded over them.
The letter J is a counterexample
The letter y is a counterexample
The letter A is a counterexample
This is a good definition
while keeping your hand still
Answer: I think it’s J, because the picture is also holding the smallest finger up (the pinky) and the rest of the fingers are folded inside the palm of the hand and the thumb is folded over them, I hope this helps!!
Step-by-step explanation:
The letter J is a counter example. Option a is correct.
Letters of alphabet to be determine.
Alphabets are the sets of letters from A to Z.
Here, the little finger is up and all the finger is folded and the thumb folded over the three finger implies its 'J'.
Thus, the letter J is a counter example.

You plan on using cost-based pricing. The cost of your product is $10, and you are planning a 30% mark-up. What should the price of your product be?
Answer:
Selling price= $13
Step-by-step explanation:
Giving the following information:
The cost of your product is $10, and you are planning a 30% mark-up.
The price of the product is calculated by adding to the manufacturing costs a predetermined percentage.
Selling price= 10*1.3
Selling price= $13
Based on the cost of the product and the mark-up, the price of the product will be $13.
Price of productThis can be fund using the formula:
= Cost of product x ( 1 + markup percentage)
Solving gives:
= 10 x ( 1 + 30%)
= 10 x 1.3
= $13
In conclusion, the product would be $13.

At a fixed operating setting, the pressure in a line downstream of a reciprocating compressor has a mean value of 12.0 bar with a standard deviation of 1.0 bar based on a very large data set obtained from continuous monitoring.
Required:
What is the probability that the line pressure will exceed 13.0 bar during any measurement?
Answer:
P [ Z > 13 ] = 0,1587 or P [ Z > 13 ] = 15,87 %
Step-by-step explanation:
The probability that the line pressure will exceed 13.0 bar is:
P [ Z > 13 ] = 1 - P [ Z ≤ 13]
And P [ Z ≤ 13] will be find in z table for z (score) =
z ( score) = ( Z - μ₀ ) / σ
z (score) = (13 - 12 )/1
Then from z-table we find
P [ Z ≤ 13] = 0,8413
Finally
P [ Z > 13 ] = 1 - P [ Z ≤ 13]
P [ Z > 13 ] = 1 - 0,8413
P [ Z > 13 ] = 0,1587 or P [ Z > 13 ] = 15,87 %
Find the solution of the system of equations . - 5x + 9y = 11 x - 3y = - 7
how do i solve this
Answer:
Solution: x=5, y=4
Step-by-step explanation:
System of Equations
We need to solve:
- 5x + 9y = 11
x - 3y = - 7
There are several ways to solve a system of linear equations. We'll take advantage of the second equation since it has the x with coefficient 1 and solve it for x:
x = - 7 + 3y
Now replace it into the first equation:
- 5(- 7 + 3y) + 9y = 11
Operate:
35 - 15y + 9y = 11
Simplify:
35 - 6y = 11
Rearrange:
- 6y = 11 - 35 = -24
Solve:
y = -24 / -6
y = 4
Finally, since
x = - 7 + 3y
x = - 7 + 3*4
x = - 7 + 12
x = 5
Solution: x=5, y=4

Answer:
Step-by-step explanation:
y= -2x+5
From the point (4,-3) , ince the slope is -2, you start counting 2 up 1 left 2up 1 left.....( or 2down,1 right,2 down 1 right......) But you choose the first to know when you are going to cross the y line
When you reaches the y coordinate you are at 5
So the line intercepts at positive 5

A pair of jeans was 30% off the original price. The sale resulted in $24 discount.
Answer:
$80 is the 100% original price
The sale price is $56 with 30% off and $24 in savings.
Step-by-step explanation:
We can write a proportion. We know that $24 is a 30% off discount of an unknown original price. Let's call it x. We write equal ratios of comparing percent and comparing the 24 to the original price. We then set them equal.
We then cross multiply across the equal sign from numerator to the opposite numerator.
30(x)=24(100)
30x=2400
We divide to find x.
x=80.
Since we saved $24 as a discount, the sale price would be 80-24=56.

Given a right triangle with sides of length a, b, and c and area a²+b²-c², find c/b, the ratio of the legs of the right triangle.
Answer:
4
Step-by-step explanation:
Looking at the sketch we can formulate 2 equations:
Pythag: [tex]b^{2} +c^{2} =a^{2}[/tex]
Area of triangle= [tex]\frac{1}{2} bc[/tex]
But area also = [tex]a^{2} +b^{2} -c^{2}[/tex] (from the question)
Therefore [tex]\frac{1}{2} bc[/tex] = [tex]a^{2} +b^{2} -c^{2}[/tex]
But we can sub in the expression for [tex]a^{2}[/tex] from pythag. ([tex]b^{2} +c^{2} =a^{2}[/tex])
[tex]\frac{1}{2} bc= b^{2} +c^{2} +b^{2} -c^{2}[/tex]
[tex]\frac{1}{2} bc=2b^{2}[/tex]
[tex]bc=4b^{2}[/tex]
[tex]c=4b[/tex]
[tex]c/b= 4b/b=4[/tex]
