A store charges $8.95 for an 8 ounce jar of maple syrup. The price for a 10 ounce jar of the same brand is $12.00. Which jar is the better buy? What is the difference in the unit prices? If necessary, round to the nearest cent.

A) 8 ounce jar; $0.08
Eliminate

B) 8 ounce jar; $0.15

C) 10 ounce jar; $.12

D) 10 ounce jar; $0.08

Answers

Answer 1

Answer: Problem 1- C. Like terms is when there is the same variable in different places in the problem. Problem 2-A, because for B, if u give them 4 cars for each person, you would need 40 plus the 3 remainder. C is different too because if u give them 3 each, four would remain. D is just like B so the final answer is A. Problem 3- the answer is 8 ounce jar, $0.08. You can find the unit price of it by dividing the ounce amount and the price, then subtract by the both unit prices.

Volunteers at an animal shelter are building a rectangular dog run so that one shorter side of the rectangle is formed by the shelter building as shown. They plan to spend between $100 and $200 on fencing for the sides at a cost of $2.50 per ft. Write and solve a compound inequality to model the possible length of the dog run.

Answers

Answer:

20 ≤ L + W ≤ 40

Step-by-step explanation:

[answer is marked by ** symbol]

The perimeter (P) of a rectangle is given by the formula:

P = 2L + 2W

In this case, you want to spend between $100 and $200 on fencing, and the cost is $2.50 per foot. So, you can write the cost equation as:

Cost = 2.50 (2L + 2W)

Now, you want the cost to be between $100 and $200, which leads to a compound inequality:

$100 ≤ 2.50 (2L + 2W) ≤ $200

Now, divide each part of the compound inequality by 2.50 to isolate the expression (2L + 2W):

$100 / 2.50 ≤ 2L + 2W ≤ $200 / 2.50

40 ≤ 2L + 2W ≤ 80

Now, divide each part by 2 to find L + W:

**20 ≤ L + W ≤ 40

**This compound inequality models the possible length of the dog run. It states that the length plus the width of the dog run must be between 20 feet and 40 feet to stay within the budget of $100 to $200 for fencing.

Answer
Write and solve a compound inequality to model the possible length of the dog run.
The inequality to model the possible length of the dog run is;. 100 ≤ 2.50x ≥
200
And the possible length of the dog run is 80ft.
Minimum spending = $100
Maximum spending = $200
Cost per square feet = $2.50
let
× = possible number of square feet

Minimum spending = $100
Maximum spending = $200
Cost per square feet = $2.50
let
× = possible number of square feet
The inequality:
100 ≤ 2.50× ≥ 200
This means possible number of square feet constructed is greater than or equal to $100 or less than or equal to $200
solve:
100 < 2.50× ≥ 200
divide the inequality into 2
100 < 2.50x
× ≤ 100/2.5
× ≤40
the other part:
2.50x ≥ 200
× ≥ 200/2.50
× ≥ 80
Therefore,
the possible length of the dog leash is 80

two minutes after a skydiver opens his parachute, he has descended 1,900 feet. after 5 minutes, descended 4,750 feet. if the distance varies directly with the time, at what rate is the skydiver descending?

Answers

1,900 ft/ 2 minutes= 950 ft/minute.

4,750 ft/ 5 minutes= 950 ft/minute.

If the distance varies directly with the time, the skydiver is descending at a rate of 950 feet per minute~

1900/ 2= 950

4750/5= 950
Why do you do this? Because you are trying to find the amount of ft per minute.

Which expression is equivalent to the expression below?(6c^2+3c/-4c+2)/(2c+1/4c-2)

Answers

Answer:

-3c

Step-by-step explanation:

The given expression is:

$((6c^(2)+3c)/(-4c+2))/((2c+1)/(4c-2))$

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

$((6c^(2)+3c)/(-4c+2))/((2c+1)/(4c-2)) \n\n =(6c^(2)+3c)/(-4c+2) * (4c-2)/(2c+1)\n\n=(3c(2c+1))/(-(4c-2)) * (4c-2)/(2c+1)\n\n =-3c$

Thus, the given expression in simplified form is equal to -3c

Answer:

-3c

Step-by-step explanation:

We are given that an expression

$((6c^2+3c)/(-4c+2))/((2c+1)/(4c-2))$

We have to find an expression which is equal to given expression

Taking common 3c from nominator and -2 from denominator in dividened and 2 common in divisor then we get

$((3c(2c+1))/(-2(c-2)))/((2c+1)/(2(2c-1)))$

$(3c(2c+1))/(-2(2c-1))* (2(2c-1))/((2c+1))$

By reciprocal divisor

By canceling same factor

Then ,we get

$((6c^2+3c)/(-4c+2))/((2c+1)/(4c-2))$

=-3c

Paint costs $29.95 per gallon. Nikki needs 12.25 gallons to complete a painting project. How much will Nikki spend on paint? (Round to the nearest penny)

Answers

Since you can't by 1/4 of a bucket of paint you round 12 up to 13. next you multiply the cost of each gallon (29.95) by the number needed (13) when you do this you get 29.95*13=398.35 so she would spend $398.35

Final answer:

Nikki will spend approximately $366.56 on her painting project, taking into account the cost of $29.95 per gallon and the need for 12.25 gallons.

Explanation:

This question requires multiplication to ascertain the total amount Nikki will spend on her painting project.Nikki needs 12.25 gallons of paint to complete a painting project. The cost of paint is $29.95 per gallon With each gallon of paint costing $29.95, and Nikki needing 12.25 gallons, you would multiply these two values together. So, $29.95 * 12.25 equals approximately $366.56
