) A gas station owner finds that for every penny increase in the price of gasoline, she sells 1516 fewer gallons of gas per week. How much more or less gas will she sell if she raises the price by 10 cents per gallon? If she decreases the price by 2 cents per gallon?
Answer:
a) 15160 gallons
b) 3032 gallons
Step-by-step explanation:
Given that for every penny increase in the price of gasoline there is a decrease of 1516 gallons sold per week
a) when she raises the price by 10 cents per gallon
There will be a decrease of ( 1516 * 10 ) gallons sold per week i.e. = 15160 gallons
b) when she decrease the price by 2 cents per gallon
There will be an increase ( 2 * 1516 ) gallons sold per week i.e. = 3032 gallons
The drama club at NAMS sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200. They need to keep track of how many of each type drink was sold so that they can make predictions for future sales. Monica knows that they used 275 cups that night. If the hot chocolate sells for 75 cents and coffee sells for 50 cents, how much of each type of drink were sold?
Answer:
Coffee = 25
Hot Chocolate = 250
Step-by-step explanation:
Coffee: c
Hot Chocolate: h
0.75h + 0.50c = 200
h + c = 275
h + c = 275
h = 275 - c
0.75h + 0.50c = 200
0.75(275 - c) + 0.5c = 200
206.25 - 0.75c + 0.5c = 200
-0.25c = -6.25
-0.25c/-0.25 = -6.25/-0.25
c = 25
0.75h + 0.5(25) = 200
0.75h + 12.5 = 200
0.75h = 200 - 12.5
0.75h = 187.5
0.75h/0.75 = 187.5
h = 250
Check: c = 25; h = 250
0.75h + 0.50c = 200
h + c = 275
0.75(250) + 0.5(25) = 200
187.5 + 12.5 = 200
200 = 200
h + c = 275
250 + 25 = 275
275 = 275
The drama club sold 250 hot chocolates and 25 coffee drinks.
EquationEquation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the number of hot chocolate and y represent the number of coffee. From the question the equation are:
x + y = 275 (1)0.75x + 0.5y = 200 (2)From both equations:
x = 250, y = 25

Six students collect buttons for a project. The students have 10, 14, 15, 12, 13, and 14 buttons. They divide the buttons evenly so that each student receives the same number of buttons. How many buttons does each student receive?
Answer:
13 buttons
Step-by-step explanation:
The first step is to add the buttons received by the 6 students.
= 10 + 14 + 15 + 12 + 13 + 14
= 78 buttons
Therefore the number of buttons received by each students can be calculated as follows
= 78/6
= 13 buttons
Hence each student will receive 13 buttons

Can sides of a triangle have lengths 3,4,9
Answer:
yes
Step-by-step explanation:
No, the lengths 3, 4, and 9 cannot form the sides of a triangle.
What is Triangle Inequality?The triangle inequality is a fundamental geometric principle that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
We have sides as 3, 4 and 9.
For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.
In this case, let's check if this condition is satisfied:
3 + 4 = 7
7 is less than 9
Therefore, these lengths do not satisfy the triangle inequality theorem, and a triangle cannot be formed with side lengths 3, 4, and 9.

Step-by-step explanation:
We are informed that the expression below represents Brianna’s age in
terms of m, Molly’s age.
3m − 5.
This shows that 3m simply means that 3 times of Molly's age while the -5 represent less than 5. This will now be:

How to solve the given inequality?
Here we have the inequality:
-3.55g ≤ -28.4
To solve this, we need to isolate g, we can divide both sides by -3.55
g ≤ -28.4/-3.55 = 8
g ≤ 8
Then we must have a black dot at x = 8, and we shade the region to the left of it, meaning that the correct graph is the last one.

Write an inequality for the graph below
Answer:
y > -1/4x + 4
Step-by-step explanation:
First find the equation of the line itself, which is y = -1/4x + 4, then determine if graph shades above the line or below the line. If it shades above which is true in this case, it will be greater than. If it shades below which does not occur in this case, it will be less than. Because the line is dashed and not solid, it will just be greater than or less than.
Therefore y = -1/4x + 4 → y > -1/4x + 4 [Shades above the line, line is dashed].
