Berto has $12 to put gas in his car. If gas costs $3.75 per gallon, which ordered pair relating number of gallons of
gas, x, to the total cost of the gas, y, includes the greatest amount of gas Berto can buy?
Answer:This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).
Step-by-step explanation: If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).
Basically what this assignment sais is to write a function, input the data and write input and output as an ordered pair.
[tex]f(x)=3.75x[/tex]
Where f(x) equals y and 3.75 times x is cost of number of gallons x.
So we have:
[tex]
f(x)=12\Longrightarrow 12=3.75x \\
12=3.75x\Longrightarrow x=\dfrac{12}{3.75}=3.2
[/tex]
So the ordered pair is in a form of:
[tex](x, f(x))\Longleftrightarrow(x,y)[/tex]
We have x is 3.2 and y is 12. So the ordered pair is:
[tex]\boxed{(3.2, 12)}[/tex]

Solve the equation 3x - 13y = 2 for y.
Answer:
[tex]y = \frac{3}{13}x-\frac{2}{13}[/tex]
Step-by-step explanation:
Move 3x to the other side, since 3x is being moved to the other side the sign will change from a positive to a negative
[tex]-13y = -3x+2[/tex]
Divide both sides by 13
[tex]y = \frac{3}{13}x-\frac{2}{13}[/tex]
Hey there! :)
3x - 13y = 2 ; solve for y.
In order to solve for y, we must isolate it by getting it onto its own side. We can do this by subtracting 3x from both sides.
-13y = -3x + 2
Then, divide both sides by -13.
-13y ÷ -13 = (-3x + 2) ÷ -13
Simplify.
y = 3/13x - 2/13
Therefore, [tex]y = \frac{3}{13}x- \frac{2}{13}[/tex]

C. The number of pages in the assignment
Answer:
C. The number of pages in the assignment.
A function is an expression that defines the relationship between two variables. The amount of time it takes to complete a reading assignment might be a function of the number of pages in the assignment. So, option C is correct.
What is a function?A function is an expression, that states the relationship between the variables in that expression.
Ley m and n are two variables and are related to each other with a function, f(m) = n.
So, the variable m is called the independent variable and the variable n is called the dependent variable.
Given statement:The given statement is "The amount of time it takes to complete a reading assignment might be a function of-"
From the options,
cost of the variable does not affect the time required to read and the year of publishing also does not affect the time required to read. But the number of pages in the assignment affects the time required to read. As the number of pages increases, the time required to read them also increases, and as the number of pages decreases, the time required to read them also decreases.So, here the time is a dependent variable, and the number of pages in the assignment will be the independent variable.
Thus, option c is correct.

An indoor sport exhibition is coming to the arena. Your supervisor has asked you to help set up a handball pitch and seating area as shown in the plan view below..
Use the following formulae:
Perimeter of a rectangle = 2l + 2w
Circumference of a circle = πd
π = 3.14
Area of a rectangle = lw
Area of a circle = πr²
What is the total perimeter of the pitch and seating area?
m
What is the total area of the pitch and seating area?
m2
Answer:
Perimeter: 174.8 m
Area: 1,394 sq m
Step-by-step explanation:
First, the perimeter.
Before we start, let's calculate the circumference of the half-circles at the ends of the field.
The measurement says 2,000 cm, so let's convert it to 20 m for ease.
Circumference of a circle: πd, where d = diameter.. in our case d = 20 m
Circumference of a 20m diameter circle: 20π = 62.8 m
We have 2 half circles... so the perimeter of each half-circle will be: 31.4 m
We also have 800 cm measurement for the "height" of the seating areas... let's convert that in 8 m
We also need to find out the space between the seating area... We know the whole rectangular pitch is 40 m, then we have to subtract the width of both seating areas (20 and 15 m)... so the space between them is 5m
So, starting with the upper left corner of the rectangular pitch, and working our way clockwise, we encounter the following lengths:
P = 40 + 31.4 + 8 + 10 + 8 + 5 + 8 + 25 + 8 + 31.4 = 174.8 m
The total perimeter is then of 174.8 m
For the area, we need to calculate the area of all forms:
Large rectangular pitch:
LR = 40 x 20 = 800 sq m
The two half circles, form a circle, so A = πr², where r is the radius, which is half the diameter.
AC = π (10)² = 100 π = 314 sq m
Then the seating areas:
SA1 = 25 x 8 = 200 sq m
SA2 = 10 x 8 - 80 sq m
Then, we add up everything:
TA = LR + AC + SA1 + SA2
TA = 800 + 314 + 200 + 80 = 1,394 sq m

[tex]\implies \mathsf{Ben's\;Share = 2400}[/tex]
Answer : Ben received $2400
Answer:
Ben's share = $2400
Step-by-step explanation:

What is the slope of the line y = 3?
Answer here
Answer:
The slope of the line y=3 is 0
Step-by-step explanation:
We need to find the slope of the line y =3
the general form of the equation is
y = mx+b
where m is the slope and b is the y-intercept.
Looking at the given equation
y=3
We can write it as
y =0(x) + 3
So, the slope of the line y=3 is 0
Answer:
The slope is 0
Step-by-step explanation:
Note that [tex]y = 3[/tex] is the equation of a horizontal line that intersects the y-axis at point (0, 3).
The slope of a line is a measure of how the variable y varies when x increases or decreases. In this case, the variable y always has the same value. Therefore the slope is zero.
All horizontal lines have slope [tex]m = 0[/tex]

Molly walked 3.45 miles on a hike. Her sister walked 1.23 miles. Her brother walked 0.85 miles.
Round each distance to the nearest tenth of a mile.
About how much further did Molly walk than her brother and sister combined?
a) about 1.4 miles
b) about 1.2 miles
c) about 2.4 miles
d) about 2.2 miles
____________________________________________________
Answer:
Your answer would be a) about 1.4 miles
____________________________________________________
Step-by-step explanation:
In order to solve this problem, we're going to need to round to the tenths place.
The tenths place is the decimal place to the right of the decimal.
Example: 0.54 --- 5 would be in the tenths place.
We would use the number next to it to see if we're going to round up or stay the same.
3.45 --- 4 is in the tenths place. When we look at the number next to it, 5, we would notice that it's big enough to make 4 round up. You would round 4 up to 5.
Your decimal should look like this: 3.5
1.23 --- 2 is in the tenths place. When you look at the number next to it, 3, it's not big enough for us to round it up, so we would keep the number 2 the same.
Your decimal should look like this: 1.2
0.85 --- 8 is in the tenths place. When you look at the number next to it, 5, you would see that it's big enough for you to round up, so you would round the 8 to a 9.
Your decimal should look like this: 0.9
Our rounded decimals:
3.5
1.2
0.9
Now, we have our rounded decimals. We're going to need to find how much Molly walked more than her sister and brother.
Molly walked 3.5
Her sister walked 1.2
Her brother walked 0.9
To solve that question, we would get 3.5 and subtract it with the rest of the numbers, since we are subtracting Molly's walk length to her brother and sister's combined walked length.
[tex]3.5 - 1.2-0.9= 1.4[/tex]
You should get 1.4
Therefore, Molly walked 1.4 miles more than her sister and brother combined.
A). about 1.4 miles should be your FINAL answer.

The proportions of multiple samples of registered voters who vote are normally distributed with a mean proportion of 0.38
and a standard deviation of 0 0485 What is the probability that a sample chosen at random has a proportion of registered
voters who vote between 0,37 and 0.39? Use the portion of the standard normal table below to help answer the question
The probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39, is 96.18%
Explanation:To find the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39, we need to standardize the values using the z-score formula. The z-score is calculated as (x - mean) / standard deviation. In this case, the mean proportion of registered voters who vote is 0.38 and the standard deviation is 0.0485. So, for 0.37:
z = (0.37 - 0.38) / 0.0485 = -2.0619
Using the standard normal table, we can find the area to the left of -2.0619, which is approximately 0.0191. For 0.39:
z = (0.39 - 0.38) / 0.0485 = 2.0619
Again, using the standard normal table, we can find the area to the left of 2.0619, which is approximately 0.9809.
To find the probability between 0.37 and 0.39, we subtract the smaller area from the larger area: 0.9809 - 0.0191 = 0.9618, or 96.18%.
jacob bought a total of 9 pizzas for his class party. The amount of large pizzas was twice the amount of medium pizzas .How many large and how many medium pizzas did they buy
Jacob bought 3 medium and 6 large pizzas for his class party, as the large pizzas were twice the amount of medium pizzas and the total number was 9.
Explanation:Jacob bought a total of 9 pizzas for his class party. The condition given is that the amount of large pizzas was twice the amount of medium pizzas. Let's define the number of medium pizzas as x. Therefore, the amount of large pizzas would be 2x. Since the total number of pizzas is 9, we can write the equation x + 2x = 9. Adding the terms together gives us 3x = 9. Dividing both sides of the equation by 3, we find that x = 3. This means Jacob bought 3 medium pizzas and 2 times 3, which is 6 large pizzas for his class party.

What is the probability of a dart (thrown at random) landing in the area marked F?
The probability of a dart (thrown at random) landing in the area marked F is:
1/16
Step-by-step explanation:We know that the probability of an outcome is defined as the chance of occurrence of an outcome and it is calculated as the ratio of number of favorable outcomes to the total number of outcomes.
We first make equal sections i.e. we divide the figure into equal sections and observe that:
A and D is made up of 4 sections.
B,C and E is made up of 2 sections.
F and G are made up of 1 section.
This means that the total number of sections are: 4+4+2+2+2+1+1=16
Hence,
Probability(landing on F)=1/16
( Since there are total 16 sections and F is made up of 1 )

Where "x" represents the angle of the left side of the triangle, we have that "x" is given by:
[tex]x = 180-114\\x = 66[/tex]
So we have to:
[tex]66 + 2y = 180\\2y = 180-66\\2y = 114\\y = \frac {114} {2}\\y = 57[/tex]
Finally, "y" is equal to 57 degrees.
Answer:
Option C
The value of y in the triangle is,
⇒ y = 57 degree
For this case we have by definition, that the sum of the internal angles of a triangle is 180 degrees.

Say your car doesn’t run on straight gasoline and you have to mix the oil with gas together in a specific ratio of 2.4 fl oz of oil for every gallon of gasoline. If you have 1.5 gallons of gas, how much oil should you add?
Answer:
3.6 fl oz
Step-by-step explanation:
figure out the percentage of the gallon that was used in the original ratio, in this case 1 that was used in 1.5. thats 150%
so no multiply 2.4 by 1.5 to get 3.6
to check work divide both ratios and see if its the same number (i checked)
For 1.5 gallons of gasoline, you should add 3.6 fluid ounces of oil to maintain the required ratio of 2.4 fl oz of oil per gallon of gas.
To calculate how much oil is needed for 1.5 gallons of gasoline when the mixture requires 2.4 fl oz of oil per gallon of gasoline, one can use a simple proportion:
2.4 fl oz oil / 1 gallon of gas = x fl oz oil / 1.5 gallons of gas
Solve for x to find the amount of oil needed for 1.5 gallons of gas:
x = 2.4 fl oz oil * 1.5 gallons of gas
We can multiply 2.4 fl oz by 1.5 to get the amount of oil:
x = 3.6 fl oz oil
Therefore, you should add 3.6 fluid ounces of oil to your 1.5 gallons of gasoline to achieve the correct mixture.
