Jeff left 4/5 of the pumpkin pie in the refrigerator on Saturday he ate 1/2 if what was left of the pie what fraction of the entire pie did he eat on Saturday

Answers

He ate 2/5 of the pie on Saturday.

Jeff ate 2/5 of the entire pumpkin pie on Saturday, calculated by multiplying 1/2 by the 4/5 which was left in the refrigerator.

The question asks what fraction of the entire pumpkin pie Jeff ate on Saturday if he left 4/5 of it in the refrigerator and then ate 1/2 of what was left. To solve this, we'll calculate the fraction of the pie he consumed using multiplication.

He started with 4/5 of the pie left. Eating 1/2 of what was left means he consumed 1/2 of 4/5, which can be calculated as:

(1/2) times (4/5) = 4/10 = 2/5

Jeff ate 2/5 of the entire pumpkin pie on Saturday.

Find each function value F(-7) if f(x)=8x+15

Answers

f(-7)
just sub -7 for x
f(-7)=8(-7)+15
f(-7)=-56+15
f(-7)=-41

Final answer:

To find the value of f(-7), substitute -7 into the function f(x) = 8x + 15. The value of f(-7) is -41.

Explanation:

To find the value of f(-7), we substitute -7 into the function f(x) = 8x + 15.

f(-7) = 8(-7) + 15 = -56 + 15 = -41.

Therefore, the value of f(-7) is -41.

Jorge bought a mechanical pencil for $8. A lead and eraser refill pack costs $2. Write a linear function to describe the cost of using the pencil as a function to describe the cost of using the pencil as a function of the number of refill packs.

Answers

Final answer:

The linear function to describe the cost of using the pencil as a function of the number of refill packs Jorge buys is C(x) = 8 + 2x, where C(x) is the total cost and x is the number of refill packs.

Explanation:

Jorge bought a mechanical pencil for $8, and each lead and eraser refill pack costs $2. To describe the cost of using the pencil as a function of the number of refill packs, we can write a linear function. The initial cost of the pencil is a fixed cost, and the cost of each refill pack is a variable cost.

Let's let x represent the number of refill packs, and C(x) represent the total cost of using the pencil. The linear function for the cost would then be:

C(x) = 8 + 2x

Here, $8 represents the fixed cost (the cost of the pencil), and $2 is the cost per refill pack, so 2x represents the variable cost (the cost of x refill packs).

Final answer:

The linear function that describes the cost of using the pencil as a function of the number of refill packs is Cost(x) = 8 + 2x.

Explanation:

To write a linear function that describes the cost of using the mechanical pencil as a function of the number of refill packs, we need to consider the initial cost of the pencil and the cost of each refill pack.

Let's assume x represents the number of refill packs.

The initial cost of the pencil is $8, which remains constant regardless of the number of refill packs.

The cost of each refill pack is $2, and it increases linearly as the number of refill packs increases.

Therefore, the linear function that describes the cost of using the pencil as a function of the number of refill packs is:

Cost(x) = 8 + 2x

The distance between Oswego and Syracuse is 40 miles. if the car travels 8 miles from Oswego toward Syracuse and then stops, What percent of the trip between the cities did the car complete?

Answers

Answer:

The car completed 20% of the trip between the cities.

Step-by-step explanation:

The distance between Oswego and Syracuse = 40 miles

The car traveled from Oswego towards Syracuse = 8 miles

We have to calculate the percentage of the trip that the car completed.

8 miles out of 40 miles = [tex]\frac{8}{40}[/tex]

To calculate we have to multiply it by 100 and put the mark of percentage.

[tex]\frac{8}{40}[/tex] × 100

= 0.2 × 100 = 20%

The car completed 20% of the trip between the cities.

The ratio of 7th grade students to 8th grade students in a soccer league is 17:23. If there are 200 students in all, how many are in 7th grade?

Answers

17:23....added = 40

17/40(200) = 3400/40 = 85 (7th graders)
23/40(200) = 4600/40 = 115 (8th graders)

With the help of ratios, we know that 85 students are enrolled in the 7th grade and 115 students are enrolled in the 8th grade.

What is the ratio?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.

So, first, add the raions and then multiply the fractions with total students as follows:

17 + 23 = 40

7th grade:

200 × 17/40 = 85

8th grade:

200 × 23/40 = 115

So, with the help of ratios, we know that 85 students are enrolled in the 7th grade and 115 students are enrolled in the 8th grade.

Assume that advanced students average 93% on an achievement test and regular students averaged 75%. If 100 advanced students and 300 regular students took the test, what would you expect the average to be? How many of each kind of student would be needed to get a group of 90 students who average 87% on the test? Please include work/explaination, I along with a few of my classmates are confused by this problem. We are in a chapter about systems of equations.

Answers

Average (mean) = (sum of all the data) / (# of data)

sum of all the data = (average)(# of data)

Thus for 100 students with an average of 93,
sum of all data = (93)(100) = 9300

and for 300 students with an average of 75,
sum of all data = (75)(300) = 22500

Therefore you would expect the overall average to be
(9300 + 22500) / (100 + 300) = 79.5 %

Now if there are x # of advanced students and y # of regular students, then

x + y = 90 (total # of students) and 93x + 75y = 87(x + y) (overall average)

The second equation can be simplified to x - 2y = 0

Subtracting the two equations yields

x = 60 and y = 90

Therefore you would need 60 advanced and 30 regular students.
