Answer:

The cost of one burger is $2.95

The cost of one fry is $1.45

Step-by-step explanation:

Let

x----> the cost of one burger

y---> the cost of one fry

we know that

[tex]5x+2y=17.65[/tex] ----> equation A

[tex]2x+3y=10.25[/tex] ----> equation B

Using a graphing tool

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (2.95,1.45)

see the attached figure

therefore

The cost of one burger is $2.95

The cost of one fry is $1.45

Answer:

5/6

Step-by-step explanation:

1/6 of 5 is the same:  (1/6)(5) = 5/6

Answer: 5/6

Work Shown:

Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:

5/1

So now that we've converted 5 into a fraction, to work out the answer, we put the fraction 1/6 side by side with our new fraction, 5/1 so that we can multiply those two fractions.

All you need to do is convert the whole number to a fraction and then multiply the numerators and denominators.

1 x 5

6 x 1

=

5/6

The complete and simplified answer to the question what is 1/6 of 5 is:

5/6

Hopefully this answer has helped you to understand how to find the fraction of any whole number.

Answer:

–7/2 ≤ x ≤ 5/2

Step-by-step explanation:

Given in the question an inequality

| 2x + 1 | ≤ 5

–5 ≤ 2x + 1 ≤ 5

–6 – 1 ≤ 2x + 1 -1 ≤ 6 – 1

–7 ≤ 2x ≤ 5

–7/2 ≤ x ≤ 5/2

Then the solution to | 2x + 1 | ≤ 5 is the interval –7/2 ≤ x ≤ 5/2

Graph is attach below

The solution to the absolute value inequality |2x + 1| ≤ 5 is the interval -3 ≤ x ≤ 2. To find this, two separate inequalities are solved based on the non-negative and negative cases within the absolute value. The graphical representation is a closed interval from -3 to 2 on the number line.

To solve and graph the absolute value inequality |2x + 1| ≤ 5, we need to consider two cases based on the definition of absolute value.

We then solve these two inequalities:

The solution set is the intersection of these two sets of numbers, which is -3 ≤ x ≤ 2. Graphically, this is represented on the number line as a closed interval from -3 to 2.

Answer:

Step-by-step explanation:

a² + b² = c²

8² + 7² = c²

64 + 49 = c²

113 = c²

c = √113 = 10.63 units

The length of C for the triangle is 10.63 units

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.

The value of C is calculated by using the Pythagorean theorem.

a² + b² = c²

8² + 7² = c²

64 + 49 = c²

113 = c²

c = √113 = 10.63 units

Therefore, the length of C for the triangle is 10.63 units

Since a function would mean that a customer is able to purchase 1.1 of an item or 1.5 of an item, which is false. It also means that the customers pay the same price for a different amount of items.

Answer: The answer is A

It is a function because the input can be either 1 or 2 items, but the output will always be the same price.

According to the stated relation, (# sale items purchased, price), the input is the number of sale items purchased and the output is the price. The input values of a function can be different and have the same output value. However, a function cannot have different outputs for the same input.

Answer:

y = 3

Step-by-step explanation:

Parallel lines are lines which do not intersect. If the line is parallel to the x-axis then it is a horizontal line that intercepts the y-axis at the y-coordinate of the point (4,-3). So the equation of the line is y = b where b is the y-coordinate or y-intercept. Here it is y = 3.

Answer:

x=3,2,-1,-4

Step-by-step explanation:

The roots (zeros) are the x

values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x

The angle of the waterslide, as measured by George using the folded paper, is 60 degrees. He found this by multiplying the paper angle of 20 degrees by the number of paper angles (3) that fit in the slide's angle.

The question is asking for the angle made by the waterslide and the ground. Given that a sheet of folded paper forms a 20-degree angle, and three of these paper angles fit in the angle made by the slide, we need to find the total angle.

To solve this problem, you simply multiply the angle of the paper by the number of paper angles that fit in the slide's angle. Here's how you do it:

So, the angle of the waterslide is 60 degrees.

The angle of the waterslide is approximately 6.67 degrees.

The angle of the waterslide can be found by dividing the angle formed by the folded paper by the number of folded paper angles that fit in the waterslide angle.

In this case, the angle formed by the folded paper is 20 degrees, and the number of folded paper angles that fit in the waterslide angle is 3.

Therefore, the angle of the waterslide is 20 degrees divided by 3, which is approximately 6.67 degrees.

The equation was solved step by step to find that Roman initially had $20.

Roman has a certain amount of money. If he spends $15, then he has 1/4 of the original amount left. To find out how much money Roman had originally, we can set up an equation. Let's call the original amount of money x. After spending $15, Roman has x - 15 dollars left, which we are told is 1/4 of the original amount, x.

So, the equation we can write is:
x - 15 = 1/4 x

To solve for x, we multiply each side of the equation by 4 to get rid of the fraction on the right side:
4(x - 15) = x

Which simplifies to:
4x - 60 = x

Then we subtract x from both sides to get x on one side:
3x - 60 = 0

Now, we add 60 to both sides to solve for x:
3x = 60

Finally, we divide both sides by 3 to find x:
x = 20

Therefore, Roman originally had $20.

The question deals with the distribution of students' residences relative to their school. Calculations suggest 22% live between 1 and 2 miles away, 10% live between 2 to 3 miles away, and the remaining students live more than 3 miles away from the school.

The question relates to the distribution of students' residences in relation to the school. Given that, at one school, half of the students live within 1 mile, 78% live within 2 miles, and 0.1 of the students live between 2 and 3 miles from the school. This implies that 22% of students live between 1 and 2 miles of the school (the difference between 78% and the half who live within 1 mile), and 0.1 of the students live further than 2 miles but less than 3 miles from the school. So, the remaining students, which is 100% minus (half + 22% + 0.1*100%), live more than 3 miles away from the school.

To find the probability that a randomly chosen student at the local community college lives within five miles of the campus or receives some kind of financial aid, the formula for the union of two events can be used. Substituting the given probabilities, the probability is found to be 0.35.

To find the probability that a randomly chosen student at the local community college lives within five miles of the campus or receives some kind of financial aid, we need to understand the given information.

We know that 20% of the students live within five miles of the campus and 30% receive financial aid. Of those who live within five miles, 75% receive financial aid.

To find the probability, we can use the formula for the union of two events:

P(A or B) = P(A) + P(B) - P(A and B)

In this case, A represents living within five miles of the campus and B represents receiving financial aid. Substituting the given probabilities, we have:

P(lives within five miles or receives financial aid) = 0.20 + 0.30 - (0.20 * 0.75)

P(lives within five miles or receives financial aid) = 0.20 + 0.30 - 0.15

P(lives within five miles or receives financial aid) = 0.35

Min's hose will fill up 14 gallons of water if it runs for 2/3 of an hour, based on its rate of 21 gallons per hour.

Explanation:

The question asks us to calculate how many gallons of water Min's hose can pump if it runs for 2/3 of an hour, given that it pumps water at a rate of 21 gallons per hour.

First, we need to find out how much water the hose would pump in one hour and then calculate 2/3 of that amount:

Full capacity in one hour: 21 gallons

Capacity in 2/3 of an hour: (21 gallons) * (2/3) = 14 gallons

So, Min's hose will fill up 14 gallons of water if it runs for 2/3 of an hour.
