Heather works at the library. Her weekly income is directly proportional
to the number of hours she works. Last week she worked 16 hours and
earned $116. How much would she earn if she could work 20 hours?
Answer:
$145
Step-by-step explanation:
When you do this type of problem, you want to find the unit rate. In order to do that you divide $116 by 16, and you get $7.25 (how much she make in one hour). Then you multiply $7.25 by 20, and get $145.

What is the x intercept for 6x - 7y = 42
Answer:
(7,0)
Step-by-step explanation:
Answer:
x = 7 (7,0)
Step-by-step explanation:
6x - 7y = 42
cancel out the y
6x -7 (0) = 42
6x = 42
divide both sides by 6
x = 7

Eugene ate 20% of the Christmas cookies his
grandmother made. If he ate 8 cookies, how
many are left?
Answer:
There are 32 cookies left
Step-by-step explanation:
There are c cookies when we started
c* 20% = 8 cookies
Change to decimal form
c * .20 = 8
Divide each side by .2
c * .2 / .2 = 8/.2
c =40
There are 40 cookies when we started
40 -8 = 32
There are 32 cookies left

Jonathan is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months. Write an equation for C,C, in terms of t,t, representing the total cost of the gym membership over tt months.
Answer:
C(t) = 25+34.37t
Step-by-step explanation:
It is given that,
The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months.
We need to write an equation for C in terms of t representing the total cost of the gym membership over t months.
At t=0, Jonathan pays $25 as joining fee.
Equation will be :
C(t) = Co+kt
Initially, Co = 25
C(t) = 25
At t = 8,
C(8) = 25 + k(8) = 300
8k = 275
k = 34.37
⇒ C(t) = 25+34.37t
Hence, this is the required equation.

Answer:
x = 47°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the given angles from 180 for x
x = 180° - (31 + 102)° = 180° - 133° = 47°
19. Which graph best represents the solution set of -4x s 6y - 54?
Answer:
I believe the answer is A and I'm sorry if I'm wrong
graph best represents the solution set of -4x <- 6y - 54 graph C. Option C is the correct option.
graph best represents the solution set of -4x < -6y - 54.
Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Since the Question seems to be incomplete, The Correct inequality in the question could be -4x < -6y - 54.
Here, graph C represents the inequality. Because y-intercept is y = -9
and the x-intercept for the inequality is x = 13.5. And it's below shaded and no boundary element can be included because of < sign.
Thus, the graph best represents the solution set of -4x < -6y - 54 graph C. Option C is the correct option.

Step-by-step explanation:
Write an equation of the line in slope-intercept form.
f(3)=-2, f(0)=1
Answer:
The equation of the line in slope-intercept form is y = -x + 1
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept ⇒ value y at x = 0The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ f(x) = y ⇒ is the function of the set of ordered pairs (x, y)
∴ f(3) = -2 is the point (3, -2)
∴ f(0) = 1 is the point (0, 1)
∴ x1 = 3 and y1 = -2
∴ x2 = 0 and y2 = 1
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{1--2}{0-3}[/tex] = [tex]\frac{1+2}{-3}[/tex] = [tex]\frac{3}{-3}[/tex]
∴ m = -1
→ Substitute it in the form of the equation above
∵ y = -1(x) + b
∴ y = -x + b
∵ b is the value of y at x = 0
∵ at x = 0, y = 1
∴ b = 1
∴ y = -x + 1
∴ The equation of the line in slope-intercept form is y = -x + 1
A truck travels 2,400 miles in 60 hours going the same distance each hour. How many miles does the truck travel each hour?
Answer:
The truck travels 40 miles per hour.
Step-by-step explanation:
[tex] \frac{2400 \: miles}{60 \: hours} = \frac{x}{1 \: hour} \\ \\ \frac{60x}{60} = \frac{2400}{60} \\ \\ x = 40[/tex]
In the first 8 overs the bowling rate of a cricketer is 4.5, In the last two over by giving how much run the bowling rate will be 5?
Answer:
In the last two overs, the bowler gave 14 runs.
Step-by-step explanation:
The bowling rate of 4.5 in the first 8 over means he gave 32.5 runs.
i.e.
Score given in first 8 overs = 4.5 × 8 = 36
Given that the bowling economy 5 at the end of 10 overs means the bowler must have given 10 × 5 = 50 score in the total 10 overs.
so, subtract 36 from 50 to get the score he will be giving in the last two overs.
i.e. score given the last two overs = 50 - 36 = 14
Therefore, in the last two overs, the bowler gave 14 runs.

The volume of a single layer in a rectangular prism is 9 cubic centimeters. There are 6 layers in the rectangular prism. What is the total volume, in cubic centimeters, of the rectangular prism?
Answer:
Total volume of the rectangular prism = 54 cubic centimeters
Step-by-step explanation:
Volume of a single layer in a rectangular prism = 9 cubic centimeters
There are 6 layers in the rectangular prism
What is the total volume, in cubic centimeters, of the rectangular prism?
Total volume of the rectangular prism = Volume of a single layer in the rectangular prism × number of layers in the prism
= 9 cubic centimeters × 6 layers
= 54 cubic centimeters
Total volume of the rectangular prism = 54 cubic centimeters

Richard bought 3 pounds of bananas for $1.50. A banana weighs about 8 ounces and there are 16 ounces in a pound. At this rate, how many bananas can Richard buy for $5?
Answer:
Richard can buy 20 bananas for $5
Step-by-step explanation:
∵ Richard bought 3 pounds of bananas for $1.50
∵ 1 pound = 16 ounces
∴ 3 pounds = 3 × 16 = 48 ounces
→ That means Richard bought 48 ounces for $1.50
∴ The cost 48 ounces = $1.50
∵ A banana weighs about 8 ounces
→ Let us find 48 ounces equal to how many bananas
∵ 48 ÷ 8 = 6
∴ The 48 ounces are the weighs of 6 bananas
∴ The cost of 6 bananas = $1.50
→ To find how many bananas can he buy by $5, use the ratio method
→ Cost : Banana
→ 1.50 : 6
→ 5 : x
→ By using cross multiplication
∵ 1.50 × x = 5 × 6
∴ 1.50x = 30
→ Divide both sides by 1.50
∴ x = 20
∵ x is the number of bananas
∴ Richard can buy 20 bananas for $5

Use the graph of function g to answer the following questions
What is the value of g(1)
The value of g(1) is 2 because the graph represents the greatest integer function, the answer is 2.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The graph of the greatest integer function is shown in the picture:
From the graph:
g(1) = 2
g(2) = 4
g(3) = 4
g(4) = 4
g(5) = 4
And so on
Thus, the value of g(1) is 2 because the graph represents the greatest integer function, the answer is 2.
