A water tank holds 880 gallons but is leaking at a rate of 5 gallons per week. A second water tank holds 1,100 gallons but is leaking at a rate of 9 gallons per week. After how many weeks will the amount of water in the two tanks be the same?
Answer:
62 weeks
Step-by-step explanation:
What we need is to represent the ratios in expression
For example if we have 992 gallons and the leaking is 5 gallons per week, the expression for the gallons after every week is
992-5x
x is the weeks
And the other case the expressions is
1240-9x
The question is the weeks for the amount being the same, then every equation can be equal to Y and it represent the same amount
992-5x=y
1240-9x=y
in both the y is the same, then
992-5x=1240-9x
992-1240=-9x+5x
-248=-4x
-248/-4=x
62=X
and that is the weeks we need for the amount being the same in both tanks
Answer:
62 weeks correct me if i'm wrong

Step-by-step explanation:
Use the system of equations to answer the questions.
5x+4y=3
y=−2x+6
The value of y from the second equation is substituted back into the first equation. What is the resulting equation?
What is the value of x?
What is the value of y?
The resulting equation after substitution is
5x + 4(-2x + 6) = 3
quite literally you replaced y with what it equals (as said in the second equation)
you then distribute the 4 within the parenthesis
5x + -8x + 24 = 3
You make it easier
5x - 8x +24 = 3
you combine like terms
-3x + 24 = 3
you subtract 24 from both sides
-3x = -21
you divide both sides by -3
meaning x = 7
you then use that value x = 7 and substitude it for the x in the other equation.
That makes the y equation
y = -2(7) + 6
you then solve
y = -14+6
y = 6 - 14
y = -8
What is the scale factor of this dilation?

i need help please
Answer:
1/2 or 2
Step-by-step explanation:
If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.
The scale factor of the dilation is 1/2.
What is scale factor?Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given:
Before dilation
AC= 8, BC= 10 abd AB= 6
After dilation
AC= 4, BC= 5 and AB= 3
Now, scale factor
Scale factor = Dimensions of the new shape / Dimensions of the original shape.
So,
scale factor = 4/8 or 5/10 or 3/6 = 1/2
Hence, the scale factor is 1/2.

Line d is parallel to line c in the figure below.
Parallel lines d and c are intersected by lines q and p to form 2 triangles. At lines d and p, the angle is 2, at d and q, the angle is 1, and at q and p, the angle is 3. At lines c and q, the angle is 4, at p and c, the angle is 5, and the third angle is 6.
Which statements about the figure are true? Select three options.
Vertical angles prove that Angle 2 is congruent to angle 5.
In the two similar triangles, Angle 1 and Angle 4 are alternate interior angles.
Vertical angles prove that Angle 3 is congruent to angle 6.
The triangles are similar because alternate interior angles are congruent.
In the two similar triangles, Angle 2 and Angle 4 are corresponding angles.
The triangles are similar because the corresponding sides are congruent.

You earn $56 walking your neighbor's dog for 8 hours. Your friend earns $36 painting your neighbor's fence for 4 hours.
What is your pay rate? And What is your friend's pay rate?
Answer:
Your pay rate is:
$ 7 per hour
Your friend's pay rate is :
$ 9 per hour
Explanation:
So if it takes you 8 hours to make $ 56 , you can just divide the total money earned by the time. So it would be 56 ÷ 8 which is 7 .
And if takes your friend 4 hours to make $ 36 , you can divide like we just did . So it would be 36 ÷ 4 which is 9 .
So you make $ 7 per hour and your friend makes $ 9 per hour.

What is the probability of rolling an even number and then an odd number when rolling two number cubes?
Size of sample spaces =
Number of desired outcomes =
P(first is even and second is odd) =
Answer:
First answer = 36
Second answer = 9
Third answer =1/4
Step-by-step explanation:
The probability of rolling an even number and then an odd number is 1/4.
What is Probability?Probability is simply the chance of getting an event from a sample space. Total probability of all the outcomes in an experiment will be always 1.
Probability of an event can be found by dividing the number of desired outcomes with the total number of outcomes.
Here two number cubes are rolled. Each number cube has total 6 outcomes.
If the sample space consists of all the outcomes of first and second number cubes,
Size of sample space = 6² = 36
We have to find the probability of rolling an even number on the first cube and then an odd number on the second cube.
There are 3 chances of having an even number for the first cube which are 2, 4 and 6.
There are 3 chances of having an odd number for the second cube which are 1, 3 and 5.
Therefore number of desired outcomes = 3² = 9
Probability (first is even and second is odd) = Number of desired outcomes / Size of the sample space
Probability (first is even and second is odd) = 9/36 = 1/4
Hence the probability of getting an even number on the first number cube and then an odd number on the second cube is 1/4.
