Answer:
Length = 11 1/3 ft; Width = 4 2/3 ft
Step-by-step explanation:
First question:
The length is 2 more than twice the width, so
L = 2W + 2
Second question:
2L + 2W = 32
L = 2W + 2
Since the second equation is already solved for L, we can use the substitution method. Replace L of the first equation with 2W + 2, and solve for W.
2L + 2W = 32
2(2W + 2) + 2W = 32
4W + 4 + 2W = 32
6W = 28
W = 28/6 = 14/3 = 4 2/3
L = 2W + 2 = 2(14/3) + 2 = 28/3 + 6/3 = 34/3 = 11 1/3
L = 11 1/3
W = 4 2/3
Answer: Length = 11 1/3 ft; Width = 4 2/3 ft

An irregular polygon is shown below:
The area of the irregular polygon is ____ square units.
Answer:
26 Units Squared
Step-by-step explanation:
We can split the polygon into different sections the first section 4 units * 4 units = 16 units squared then by analyzing the other section we can find it is 5 units by 2 units = 10 units added together is 26 Units Squared

A paper cup is dropped and its landing position is recorded. The cup can land on the side, on the open end, or on the closed end. The results of 20 trials are shown in the table below:
A chart shows tally marks. Main title for the chart is Paper Cup Experiment. The title for the second column is Number of times occurred. The tally mark corresponding to open shows a set of 4 vertical lines cut by a slanting line. The tally mark corresponding to closed shows a set of 4 vertical lines cut by a slanting line and a set of 3 vertical lines. The tally mark corresponding to side shows a set of 4 vertical lines cut by a slanting line and a set of 2 vertical lines.
Based on the table, which of the following best compares the experimental probability of the cup landing on its open end with the experimental probability of the cup landing on its closed end? (1 point)
The probabilities are equal.
The probability of landing on the open end is greater.
The probability of landing on the closed end is greater.
No conclusion can be made.

The approximate number of pink chips is 40. Here's why: what you need to do is set up the problem as shown below. 12 goes above 30 because you have to know what the total number of chips chosen is in order to relate it to 100 chips. From there, all you have to do is cross-multiply and divide (or my middle school teacher used to call it fish.... I'll explain why). First you are going to draw a line from the 100 to the 12 and multiply them. then you are going to curve the line that you will draw from the 12 to the 30 and divide the product of 12 and 100 by 30. Then you will draw a line from the 30 to the X meaning that the quotient that you find from the product of 120 and 100 divided by 30 equals X. Hope that helps.

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.
If 150 televisions are sold, what is the profit?

The value of a share of stock decreases in value at a rate of $1.40 per hour during the first 3.5 hours of trading. Enter and solve an equation to find the decrease in the value of the share of stock during that time. Let x represent the decrease in value of the share of stock during 3.5 hours.
The equation to find the decrease in the value of the share of stock is x / _____ = _______
The decrease in value of the share of stock during 3.5 hours was $________
Answer:
x/3.5h = -$1.4
So, x = -$1.4 * 3.5h
= -$4.9
Step-by-step explanation:
Since your losing $1.4 every hour, the 1.4 is supposed to negative.
Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours
and get -$4.9.

Michelle says that 4,902 × 0.001 is the same as 4,902 ÷ 103. Which explains whether she is correct?
A. She is correct because 0.001 = 103.
B. She is correct because multiplying by 0.001 is the same as dividing by 103.
C. She is incorrect because 4,902 × 0.001 = 0.4902 and 4,902 ÷ 103 = 4.902.
D. She is incorrect because multiplication makes a number greater and division makes a number less.
Answer:
D.) she is incorrect because multiplication makes a number greater and division makes a number less
Step-by-step explanation:

Michelle has a total debt of $28. She is trying to pay back $2 each week for the next 3 weeks. If Michelle is successful, which amount will represent the change in the amount of her debt?
Answer:
$22
Step-by-step explanation:
She gives 2 dollars per week for 3 weeks.
If she gives back 2 dollars each 3 weeks, we would solve for 2 x 3
2 x 3 = 6
28 - 6 = 22
$22 dollars represents her amount of debt.
Answer:
-6
Step-by-step explanation:
$28
$2/week
$28 - (2x3) = $22
$22 - $28 = -$6
