Answer: The average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
Step-by-step explanation:
Given: Change in water level in [tex]1 \dfrac23[/tex] week = [tex]-1\dfrac12[/tex] inches = [tex]-\dfrac32[/tex] icnhes
To find : The average rate at which the water level changed every week.
i.e. Change in water level per week.
As [tex]1\dfrac23 = \dfrac52[/tex]
Change in water level in 1 week = [tex]-\dfrac{3}{2}\div\dfrac52 = -\dfrac32\times \dfrac25= -\dfrac35[/tex]
Hence, the average rate at which the water level changed every week = [tex]-\dfrac35[/tex] inches per week.
We want to find the average rate of change at which the water level changed in a given time period.
We will find that the average rate of change is:
[tex]r = - 0.9 in/week[/tex]
We define the average rate of change as the quotient between the total change and the time it takes.
Here we have:
total change = -(1 + 1/2) in
Time = (1 + 2/3) weeks
Then the average rate of change is:
[tex]r = \frac{-(1 + 1/2) in}{(1 + 2/3) weeks} = - 0.9 in/week[/tex]
This means that the water level decreases, in average, 0.9 inches per week.

The figure above shows a cement block of
36 cm x 20 cm x 9 cm with two 10 cm x 8 cm
openings. What is the weight of the cement block
to the nearest gram? (The density of cement is
1.7 gram/cm
cm)
A) 5,040
B) 6,048
C) 7,560
D) 8,568
Answer:
D) 8,568Step-by-step explanation:
weight = (volume of block - volume of slots) x density of block
= (30 * 20 * 9) - (2 x (10 * 8 * 9)) x 1.7
= (5400 - 1440) x 1.7
= 8,568
Volume is a three-dimensional scalar quantity. The correct option is D, 8568 grams.
What is volume?A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
The volume of the complete block is,
Volume = 36 cm x 20 cm x 9 cm = 6480 cm³
The volume of the opening is,
Volume of the opening = 2 × 10 cm x 8 cm × 9cm = 1440 cm³
Therefore, the weight of the cement block to the nearest gram is,
Weight = (6480 -1440)cm³ × 1.7 gram/cm³
= 8568 grams

Answer:
RHS
Step-by-step explanation:
It is given that XY is the perpendicular bisector of WZ. This means that it forms 90-degree angles at Y. (angle XYZ and angle XYW are 90 degrees). (R)
Since there is a right angle at Y, XZ and XW are the hypotenuses. (H)
There is a common line between triangle XYZ and XYW and that is XY. (S)
Therefore you can prove ΔXYZ ≅ΔXYW because of RHS
if a translation take triangle CAT to C’A’T’, what is A’T’?
Answer:
Option (1)
Step-by-step explanation:
If a translation takes the triangle CAT to triangle C'A'T', transformation will be the rigid transformation or Isometry.
By the definition of rigid transformation, shape and size of the image and preimage remains the same.
Therefore, length of the sides of ΔC'A'T' will remain same as ΔCAT after the translation.

A number n square plus 12 is the same as the
quotient of p and 4.
Answer:
n² + 12 = p/4
or
n² + 12 = p ÷ 4
Step-by-step explanation:
The number n is squared, and you have to add 12 to complete the equality. So n squared plus 12 will equal p divided by 4.
whats the answer to 5(x−2)+3x−4= 38
Answer:
x = 6.5
Step-by-step explanation:
5(x−2)+3x−4= 38
5 times x, 5 times -2 =
5x - 10 + 3x - 4 = 38
Combine like terms
5x + 3x = 8x
8x - 10 - 4 = 38
Add 10
8x -10 +10 -4 = 38 +10 =
8x -4 = 48
Add 4
8x -4 +4 = 48 +4
8x = 52
Divide by 8
8x/8 = 52/8 =
x = 6.5
What is an equation of the line that passes through the point (2,-2) and is parallel
to the line 5x – 2y = 4?
Answer:
y=2.5x-7
Step-by-step explanation:
First, 5x - 2y = 4
=> - 2y = 4 - 5x
y = 2.5x -2
Since the line we want to know is parallel to the given one,
its slopw would be 2.5 as well
so let the line passes through the point (2,-2) be y=2.5x+a
then 2.5* 2 +a = -2 => a = -7
Final answer: y=2.5x-7
y=5/2x-7 is equation of the line that passes through the point (2,-2) and is parallel to the line 5x – 2y = 4.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that, a line is passing through (2,-2) and is parallel to line 5x – 2y = 4.
We need to find the equation of other line.
We need to write the equation of line in slope intercept form.
5x – 2y = 4
-2y=4-5x
2y=5x-4
y=5/2x-2
The slope of line is 5/2
Since the line we want to know is parallel to the given one,
If two lines are parallel then slope of two lines will be parallel.
So the slope of line passing through (2, -2) should be 5/2.
let the line passes through the point (2,-2) be y=5/2x+c
then 5/2(2) +c = -2
c=-2-5
c=-7
Equation of line parallel to 5x-2y=4 is y=5/2x-7
Hence y=5/2x-7 is equation of the line that passes through the point (2,-2) and is parallel to the line 5x – 2y = 4.

The function has no intercepts.
Option C is the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
The x-intercept is the point on the x-axis when y= 0.
The y-intercept is the point on the y-axis when x= 0.
We see that,
There is no point on the x-axis or y-axis that the graph is touching.
So,
We can say that,
There are no x-intercepts and y-intercepts.
Thus,
The function has no intercepts.

What is the vertical distance between 580ft above sea level and 200ft below sea level. Help
Answer:
780ft Hope i helped <3
Step-by-step explanation:
Answer:
780 ft
Step-by-step explanation:
you have to think of it as adding the two and not subtracting because they are asking the total distance. The first one is above sea level so it's 580 above sea level. the second one is under sea level so 200 ft under sea level. that means that the total distance if we start from under the sea 200 ft up to the sea level and then another 580 ft to above sea level!

Answer:
This is not correct
Step-by-step explanation:
on the right side is 3.2 (x-5) this means that it represents 3.2 * (x-5). You have to multiply (according to the distributive property) 3.2 by x and 3.2 by (-5), so you get 3.2x + (3.2*-5) = 3.2x -16
The left side says 3.2x-5, that is clearly not equal to 3.2x-16.
It is impossible to say that there are infinitely many solutions as there are actually no possible solutions. Set the functions equal so it is:
3.2x-5 = 3.2x-16
solve for x by subtracting the 3.2x from the right side and the left side, then add 5 to both sides to isolate the variable with the other terms.
You get 0=11
That is not true.

4
5
Answer:
5 months
Step-by-step explanation:
Make the question into an equation where the cost of one gym equal to the cost for the other.
60x = 100 + 40x
x represents how many months
20x = 100
x = 5
It would take 5 months of membership for the costs to be the same.
The answer is 5 months.
How to make a linear equation?The linear equation is made using the constraints given in the question, examining whether the data is added, subtracted, divided, or multiplied.
How to solve a linear equation?To solve the linear equation we group the variable on the LHS and then equate it with the constant and this is done by transposing, or using an arithmetic operator on both sides.
The solution to the given problemLet the number of months taken be 'x'
SO the community fitness takes 60x money for x months
The fitness center where she works takes an amount of 100+40x for x months as registration fees are only charged once.
so equating the equation to find the value of x.
100+40x = 60x
Transposing 40x from LHS to RHS
100=60x-40x
20x = 100
Dividing the equation by 20 on both sides
x = 5
The membership costs will equal in 5 months.
