Number of chores is independent, the other is dependent

Independent variable (often denoted by x ) whose variation does not depend on that of another.
Dependent variable (often denoted by y ) whose value depends on that of another.

Independent- c (number of chores)
Dependent- d (number of dollars)

Depending on how many chores you complete will determine how much money you will earn.

Bill's new porch is rectangular, with an area of 50 square feet. If the length of the porch is two times the width, what is the perimeter of the porch?
A.30
B.40
C.50
D.60

Answers

the answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.

Tom drives 200 miles in 4 hours.
He drives the first 32 miles at an average speed of 64 mph
Work out his average speed for the rest of the journey, in mph.
Please help??

Answers

His average speed for the rest of the journey was of 48mph.

if tom is driving 200 miles in 4 hours... and drives the first 32 miles in half an hour... his speed for the rest of the trip would most likely be 48 mph because 3.5 hours are left and 168 miles are left and when you divide that it comes out to 48.

Harold is designing a patio with congruent square concrete tiles. He has 72 tiles. Use grid paper to model all the possible rectangular patios Harold could build. Label the dimensions in units. Which patio has the greatest perimeter? The least perimeter?

Answers

Answer:

(a) The possible dimensions are:

1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

(b): Patio with greatest and the least perimeter

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

Step-by-step explanation:

Given

[tex]Tiles = 72[/tex]

Solving (a): Possible rectangular models

To do this, we simply list out the possible factor pairs of 72.

So, we have:

1 unit by 72 units; 2 units by 36 units; 3 units by 24 units; 4 units by 18 units; 6 units by 12 units; 8 units by 9 units

Solving (a): Models with the least and the greatest perimeter

Perimeter (P) is calculated using:

[tex]P = 2 * (L + W)[/tex]

So:

1 unit by 72 units;

[tex]P = 2 *(1 + 72) = 146 units[/tex]

2 units by 36 units;

[tex]P = 2 *(2 + 36) = 76 units[/tex]

3 units by 24 units;

[tex]P = 2 *(3 + 24) = 54 units[/tex]

4 units by 18 units;

[tex]P = 2 *(4 + 18) = 44 units[/tex]

6 units by 12 units;

[tex]P = 2 *(6 + 12) = 36 units[/tex]

8 units by 9 units

[tex]P = 2 *(8 + 9) = 34 units[/tex]

From the calculations above:

The dimension with the greatest perimeter is: 1 by 72

The dimension with the least perimeter is: 8 by 9

two times the sum of a number and 18 is at least -21

Answers

Answer:

2x + 18 ≥ 21

x ≥ 2/3

Step-by-step explanation:

Let sum be X

2 times the sum means 2x

the sum of a number and 18 means x + 18

at least -21 means ≥ 21

put them together, and you get, 2x + 18 ≥ 21

If solving for x,

2x + 18 ≥ 21

2x ≥ 3

x ≥ 2/3

8x + 2x + 10 = 60

10x = 50

x = 5

In this assignment, you will need to design a complete Black-Box testing plan for the following program. A computer science student has to travel from home to ODU every day for class. After showing up to class late too many times due to traffic, the student made a program to tell him when he should leave the house. The time given depends on the class time and the day of the week.He came up with a few rules to make sure he gets to class on time.The normal drive time for this student is 30 minutes without traffic. He then gives himself 5 minutes to walk across campus to class from the parking lot.However, if he leaves home during the worst morning rush hour, from 6 AM - 7 AM on a weekday, he needs to add 20 minutes to his commute to account for traffic. If he leaves home during the regular morning rush hour, from 7 AM - 8 AM on a weekday, he needs to add 10 minutes to his commute to account for traffic.Mondays have the worst morning traffic, and he should instead add 30 minutes for 6 AM-7AM and 20 minutes for 7 AM 8 AM.On Saturdays and Sundays the student needs to take a different route due to road construction. This adds 6 minutes of travel time.If he leaves during the afternoon rush hour on a weekday, traffic from 4-6PM should add 15 minutes of travel time. Traffic in the afternoon is worst on Thursdays, and should instead add 20 minutes of travel time.If the class is between 9:30 AM and 11 AM he needs to arrive 10 minutes earlier for walking time because the closest parking lots are all full.The program will read data from the screen in the following format:Day_of_the_week hours:minutes AM/PMe.g.Tuesday 12:45 AMSunday 01:52 PMIf the input is not in the correct format the program will prompt the user again for the input.
