Corinne has a job selling magazines. She earns $7.50 per hour plus 20% of the total amount of her sales. She also gets an allowance of $40 per week for gas. She knows her weekly earnings can be shown using the following expression: 7.50h + 0.20s + 40 Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points) Part B: If Corinne works for 25 hours and sells $300 in magazines, how much does she earn for the week? Show your work to receive full credit. (4 points) Part C: If Corinne gets a raise and begins earning $9 per hour, would the coefficient, variable, or constant in the equation change? Why?
Part A
The coefficient would be the number that is with a variable. The coefficient of 7.50h is 7.50. The variable is h, variables can be a letter or symbol that stands for something in a equation. For this question, h stands for the number of hours Corinne works. The constant is the number that is alone in the equation. That doesn't have a variable with it. In this equation the constant would be the number 40.
Part B
To solve this I will plug in 25 into "h" in and 300 for "s" in the equation 7.50h + 0.20s + 40 and then solve it.
25 × 7.50 = $187.5.
0.20 × 300 = $60
Total: $187.50 + $60 = $247.50 + $40 = $287.50
Part C
If Corrine gets a raise and earns $9 an hour the coefficient would change. It would be 9h instead of 7.50h.

At a butcher shop, Hilda bought 6 9/20 lb of beef and some pork. She left with 17 17/25 lb of meat. Express the number of pounds of pork she bought using a decimal.
Answer:
56.15
Step-by-step explanation:
First, convert [tex]6\frac{9}{20}[/tex] lbs to a decimal. Multiply the main number (6) by the denominator (20) and then add that number to the numerator (9). The number you will get will be (6 x 20)+9 = 129. 129 is now the new numerator as an improper fraction so the improper fraction is now [tex]\frac{129}{20}[/tex].
Now make [tex]17\frac{17}{25}[/tex] lbs an improper fraction. It would be [tex]\frac{442}{25}[/tex].
Now subtract the amount of pork from the total amount of meat. [tex]\frac{442}{25}[/tex] - [tex]\frac{129}{20}[/tex] . Find a common denominator. I'm going to use 500, although there might be something less.
[tex]\frac{5615}{100}[/tex] is the result. Now you can either start dividing or simplify the fraction, which hopefully you already know how to do. 5615 ÷ 100 = 56.15

Camden is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 5 points. What would be Camden's test score out of 50 if he got 2 questions wrong? What would be his score if he got x questions wrong
Answer:
Step-by-step explanation:
Score of 2 questions = 2 *5 = 10
He got 2 questions wrong. So, 50 - 10 = 40.
Camden's test score out of 50 = [tex]\frac{40}{50}[/tex]
Score for x questions = x *5 = 5x
Camden's score if he got 'x' questions wrong = 50 - 5x
Identify the inequality for the given graph.
Answer:
We. can see there's a black point at -3.7 and an arrow going to the left.
As the arrow goes to the left, it must be less than -3.7 or less than or equal to -3.7, now, we will need to see the colour of the point to know which it is.
As there is a black point, -3.7 is also contained in this range...
What does that mean? That means it will be less than or equal to -3.7
So we know the correct option is a) less than or equal to -3.7, what we could write as ([tex]-\infty,-3.7[/tex]].

A president and vice-president for a student organization are chosen from eleven people. How many different president/vice-president combinations are possible?
Answer:
110 combinations.
Step-by-step explanation:
We are going to be choosing without replacement.
Out of 11 people, we can choose one president, but after choosing, we would be left out with 10 people to choose a vice president from.
To calculate the possible combinations of president and vice-president, we multiply 11 by 10
11 x 10
= 110
Therefore we have 110 vice-president/president possible combinations.

A hiker travels at 4 miles per hour at a heading of S 35° E from a ranger station. After 3
hours how far south and how far east is the hiker from the station?
Answer:
First, let's define our coordinates.
Let's call East as the positive x-axis and North as the positive y-axis.
Now the data that we have is:
Speed = 4 mph
Time = 3 hours.
Then the total distance traveled is:
D = 4mph*3h = 12 miles.
We also know that the angle is S 35° E.
(from east, 35° to south)
So we can write this angle as -35°.
Then if we want to know the component in South and East, we can first think this in polar coordinates
(R, θ)
where R = 12 miles, and θ = -35°
Now with this, we have that:
X = R*cos(θ) = the displacement to the east.
Y = R*sin(θ) = the displacement to the north (then -Y is the displacement to the south).
Then we have:
X = 12mi*cos(-35°) = 9.83mi
Y = 12mi*sin(-35°) = - 6.89 mi.
Then:
The displacement to the East is X = 9.83 miles
The displacement to the South is -Y = 6.89 miles.
The magnitude of southern displacement of the hiker is 6.88 miles.
The magnitude of eastern displacement of the hiker is 9.83 miles.
The given parameters;
Velocity of the hiker, v = 4 mphPosition of the hiker, θ = S 35⁰ ETime of motion, t = 3 hoursThe resultant displacement of the hiker is calculated as follows;
D = vt
D = 4 mph x 3 h
D = 12 miles
The magnitude of southern displacement of the hiker is calculated as follows;
[tex]D_y = D \times sin(\theta)\\\\D_y = 12 \ miles \times sin(35)\\\\D_y = 6.88 \ miles[/tex]
The magnitude of eastern displacement of the hiker is calculated as follows;
[tex]D_x = D \times cos(35)\\\\D_x = 12 \ miles \times cos(35)\\\\D_x = 9.83 \ miles[/tex]

Stacy sent 10 more texts than twice her little sister yesterday together they sent 46 texts how many texts did Tracy send
Answer:
Tracy sent 12 texts
Step-by-step explanation:
hope this helps
Answer:
The answer is 12 texts.
Step-by-step explanation:
Ok, so I'm assuming that Tracy is the little sister.
Stacy's texts: s
Tracy's texts: t
46 = s + t
s = 2t + 10
Substitute 2t + 10 for s in the first equation.
46 = 2t + 10 + t
46 = 3t + 10
-10 -10
36 = 3t
36/3 = 12
Tracy sent 12 texts and Stacy sent 34 texts.

1/4a + 1/3a + 8 = 22 what would be the steps to solve this
Answer:
Step-by-step explanation:
first i would combine like terms so 1/4a + 1/3a is equal to 7/12 then the equation would be 7/12a+8=22 simplify the isolate the variable so i think it A=24
Answer:
Hey there!
Step-by-step explanation:
Equation: 1/4a + 1/a + 8 = 22
(The answer is 24)
(You have to do 3 steps in order to solve this question! The steps are below!)
~1. First you have to simplify both sides of the equation.
=> (1/4a + 1/3a) + (8) = 22
=> 7/12a + 8 = 22
~2. Next, subtract 8 from both of the sides.
After you do that you will get, 14
7/12a=14
~3. Lastly, you just multiply both sides by 12/7.
(12/7) x (7/12a)
(12/7) x (14)
~Therefore, A would equal to 24.
A=24
