One number is 5 more than 9 times the other. If we represent the first number with x, we get the two numbers to be
x and
9+5x
The sum of the two numbers is 75. Plugging the two numbers into that equation, you get
x + 9+5x = 75
You can simplify to get
6x+9 = 75
By subtrating 9 from both sides, you get
6x = 66
Now you are practically done! You just need to divide both sides by 6 to get
x = 11
The two numbers were
x and
9+5x
By plugging x = 11 into both of the equations, you get
11 and
64 (64 is 55 + 9)
below is a data table showing the amount of water remaining in a swimming pool. find and interpret the rate of change.
Answer: 40 gallons per second
Step-by-step explanation:
every second, a set number of gallons is emptied from the pool. to find this amount, you essentially have to subtract the one number From one on top of it. Example: 300 - 260 = 40
You can either stop there or continue until you are confident you have the right answer
300 - 260 = 40
260 - 220 = 40
220 - 180 = 40
180 - 140 = 40

8. 15.81
9. 16.85
10. 28.17
Step-by-step explanation:
The square root of the numbers to the nearest hundredth is:
√138= 11.75
2. √405=20.12
3. √800= 28.28
4. √1150= 33.91
5. √6500= 80.62
6. √580= 24.08
7. √300= 17.32
8. √250= 15.81
9. √284= 16.85
10. √794= 28.18
The square root of a number is a value that when multiplied by itself it gives the number, For example, the square root of 16 is 4. This is because 4 x 4 = 16
Square root is denoted with this symbol √
In order to round off to the nearest hundredth, look at the number in the thousandth place, if the number is equal or greater than 5, add 1 to the hundredth value. If this is not the case, add zero to the hundredth value.
√138= 11.75
2. √405=20.12
3. √800= 28.28
4. √1150= 33.91
5. √6500= 80.62
6. √580= 24.08
7. √300= 17.32

Your neighbor Philip buys a new alarm system that has two alarms (main and backup) with a 0.01 probability of a system failure. After reading the manual, he discovers that the second alarm has a 0.05 probability of failing. What is the probability of the first alarm failing?
Answer:
0.2
Step-by-step explanation:
Let P(A) = probability of first alarm failing and P(B) = probability of second alarm failing = 0.05. Since the events are independent, we have that the probability of both alarms failing or of system failure is P(A ∪ B) = P(A) × P(B).
Since the probability of both alarms failing or of system failure, P(A ∪ B) = 0.01, then the probability of the first alarm failing P(A) = P(A ∪ B)/P(B) = 0.01/0.05 = 0.2.
So, the probability of the first alarm failing P(A) = 0.2

What’s the distance of the points (2,-9) and (-1,4)
Answer:
Step-by-step explanation:
Use the distance formula to determine the distance between the two points.
Distance = √ ( x 2 − x 1 ) 2 + ( y 2 − y 1 ) 2
Substitute the actual values of the points into the distance formula.
√ ( ( − 1 ) − 2 ) 2 + ( 4 − ( − 9 ) ) 2

A punter kicks a football into the air. The pathway of the football can be represented by the equation h=-16t^2+82t (where t= time in seconds and h= height in feet.) How long will it take the football to reach the ground.
The time required for the ball to reach the ground is 10.25 seconds
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The punter kicks the ball into the air
The equation to determine the pathway is h = -16t² + 82t
where t is the time taken in seconds to reach the height h
So ,
Time taken by the football to reach ground is calculated from the equation
At the ground , the height will be 0
So , h = 0
Substituting the value for h in the equation , we get
0 = -16t² + 82t
Adding 16t² on both sides , we get
16t² = 82t
Divide by t on both sides , we get
16t = 82
Divide by 4 on both sides , we get
4t = 41
Divide by 4 on both sides , we get
t = 10.25 seconds
Hence , the time taken by the football to reach the ground is 10.25 seconds

simplify x²-25 / 2x²-7x-15
I'm more stuck on simplifying the bottom the top part is fine
Answer:
(x+5)/(2x+3)
Step-by-step explanation:
So we know the top part is difference of two squares. So thats (x+5)(x-5)
The bottom part
Firstly you do 2 times -15= -30
Now we need to find two numbers with a difference of 7 but multiply to give 30.
30
1 x 30
2 x 15
3 x 10
5 x 6
From here we can see 3-10=-7 and multiply to make -30
So we do 2x²-10x+3x-15
simplify this in two different parts: 2x²-10x and 3x-15
2x(x-5) and 3(x-5)
Therefore we get (2x+3)(x-5)
(x+5)(x-5)/(2x+3)(x-5)
x-5 is common so they cancel each other out leaving you with
(x+5)/(2x+3)

2 bags of sunflower seeds cost $5. How much would 10 bags of seeds
cost?
Answer:
$25
Step-by-step explanation:
If 2 bags of sunflower seeds cost $5 dollars, and you need 10 bags, you can do 5 x 5, where one 5 represents the cost and the other 5 represent the packs needed, which is 5 x 2.
Thus 5 x 5 = 25, 10 bags of sunflower seeds will cost $25.
