The water level of a lake fell by 1 1/2 inches during a 1 2/3-week-long dry spell. Find the average rate at which the water level changed every week.
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.

Answer:
m<7 = 95 degrees
Step-by-step explanation:
Angle 1 = 3x + 10
Angle 4 = 4x-15
Because of the verticle angles theorum, Angle 1 and 4 are congruent.
So:
3x+10 = 4x-15
+15 +15
3x+25 = 4x
-3x -3x
25 = x
Angle 1 = 3x + 10
But now we know what x is so now its (3 times 25) + 10 which is 85
Angle 1 and 3 are a linear pair so they are supplementary (add up to 180)
180-85=95
So, Angle 3 is 95 degrees
Because of the corresponding Angles postulate, 7 and 3 are congruent
So m<7 = 95 degrees

Answer:
B.
Step-by-step explanation:
How to name a ray:
A ray is part of a line. It has an endpoint and contains all points of the line to one side of the endpoint. To name a ray, use two points on the ray. The first one must always be the endpoint. The second point is any other point on the ray. The arrowhead above the two letters always points to the right.

3(x-4)= 36
Answer:
x = 16
Step-by-step explanation:
3(x-4)=36
First we will distribute:
3x - 12 = 36
Add 12 to both sides:
3x = 48
Divide both sides by the coefficient:
x = 16
Check your work:
3 (x - 4) = 36
3 (16 - 4) = 36
3 (12) = 36
36 = 36
Final answer:
x = 16

A radio station is giving away a $100 bill to every 30th caller and movie tickets to every 10th caller. If there are 120 callers, how many callers will get both the $100 and the movie tickets?
Answer:
4 callers
Step-by-step explanation:
Because 10 is a factor of 30, we don't have to worry about it. Every 30th caller will get both rewards. 120/30=4 so the answer is 4.

3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 4 as the denominator :
28 28 • 4
28 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
x - (28 • 4) x - 112

4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-112
————— • 4 = 0 • 4

Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-112 = 0
Solving a Single Variable Equation:
4.2 Solve : x-112 = 0
Add 112 to both sides of the equation :
x = 112
One solution was found :

Rewrite the equation in Ax+By = C form.
Use integers for A, B, and C.
y+3 = 5(x+5)
y+3 = 5(x+5)
y+3 = 5x+25 ... distribute
y = 5x+25-3 ... subtract 3 from both sides
y = 5x+22
y-5x = 22 ... subtract 5x from both sides
-5x+y = 22 .... is one possible answer
5x-y = -22 ... is another possible answer
The difference is that I multiplied both sides by -1 so that the A term becomes positive.

7x^2– 19x – 6
How do I factorize this expression?
Answer:
x = 3 and x = -2/7
Step-by-step explanation:
you can multiple -6 by 7 = -42
and then find what adds into -19 but can multiply together to get -42.
In this case (x-21)(x+2) would work
then you have to divide out your 7 from both numbers,
(x-21/7)(x+2/7)
then you have to make them equal to zero
x-21/7 = 0 = x = 21/7 = 3
x+2/7 = 0 = x = -2/7
so your final answer is x = 3 and x = -2/7
