What is the area of a rectangle with vertices at (−3, −1) , (1, 3) , (3, 1) , and (−1, −3) ? Enter your answer in the box. Do not round any side lengths.

Answers

Answer 1
First, we use the formula for the distance between two points to find the width and the length of the rectangle.

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Using the formula above, we get

Width = distance between (-3,-1) and (1,3) = [tex] \sqrt{(1-(-3))^2 + (3-(-1))^2} = \sqrt{32} = 4 \sqrt{2} [/tex]

Length = distance between (1,3) and (-1,-3) = 
Answer 2
16 square units. Using the pythagorean theorem, calculate the length and width of the rectangle. sqrt((-3 - 1)^2 + (-1 - 3)^2) = sqrt(-4^2 + -4^2) = sqrt(16+16) = sqrt(32) = 4sqrt(2) sqrt((1-3)^2 + (3-1)^2) = sqrt(-2^2 + 2^2) = sqrt(4 + 4) = sqrt(8) = 2sqrt(2) You can check using the rest of the points to insure you actually have the length and width of the rectangle, I've done so, but am not going to demonstrate it here. We now have the length and width of the rectangle at 4sqrt(2) and 2sqrt(2). So just multiply them together to get the area, so 4sqrt(2) * 2sqrt(2) = 4 * 2 * sqrt(2) * sqrt(2) = 4 * 2 * 2 = 16 Therefore the area of the rectangle is 16.

A cell phone service provider offers two plans. Plan A includes a fee of $25 per month and charges $0.25 for every call. Plan B includes a fee of $40 per month and offers unlimited calls. For what number of phone calls is the cost of plan B less than the cost of plan A?

Answers

This problem is a classic algebra problem.  Let's use our variables to create some equations.

The total cost of Plan A is mx+b, where b is the inital monthly cost of the plan and m is the rate charged per call.  x is the number of phone calls received in the month.  With this in mind, we know that the total cost of one month of Plan A is f(x)=.25x+25

The total cost of Plan B is simpler.  It's just $40.

Now we need to figure out the number x that will make Plan B<Plan A.

40<.25x+25

x=60

Therefore, Plan B costs less than Plan A after 60 phone calls have been made.

There are 60 phone calls is the cost of plan B less than the cost of

plan A.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Plan A includes fee of $25 per month and charges $0.25 for every phone call.

And, Plan B includes a fee of $40 per month and offers unlimited calls.

Let number of phone calls for the cost of plan B less than the cost of

plan A = x

So, For plan A; we can formulate;

The total cost of the plan A ,

f (x) = 25 + 0.25x

And, For plan B;

The total cost of the plan B,

f (x) = 40

Now, To check the number of phone calls for the cost of plan B less than the cost of plan A, we can formulate;

40 < 25 + 0.25x

Solve for x, it gives the number of phone calls.

40 < 25 + 0.25x

Subtract 25 both side;

40 - 25 < 25 + 0.25x - 25

15 < 0.25x

Divide by 0.25;

60 < x

So, We can say that;

There are 60 phone calls is the cost of plan B less than the cost of

plan A.

Answers

Lost (⬅key word) 4 is equal to -4
On 2 plays that is times 2

A negative times a positive is negative
-4×2= -8
Hope this helped you☺
Final answer:

The football team lost 4 yards on 2 plays in a row, resulting in a change in field position of -8 yards.

Explanation:

The football team lost 4 yards on 2 plays in a row. To determine the change in field position, we need to subtract the total yardage lost from the starting field position. Assuming the starting field position was at the 50-yard line, the change in field position would be -4 yards x 2 plays = -8 yards. Since the team lost yardage, the change in field position would be a negative value.

Answers

The cost of 1 adult for the given games using the various parameters to create a simultaneous equation gives; $8

How to create simultaneous equations?

Let cost of adults be x and let cost of kids be y.

Now,  there were 7 adults and 20 kids at Pump and Jump Land and the cash collected was $236. Thus, we can say that;

7x + 20y = 236    -----(1)

Similarly, there were 21 adults and 50 kids for a total amount of $618. Thus;

21x + 50y = 618   -----(2)

Solving both equations simultaneously gives;

x = $8 and y = $9

Evaluate 3x + y when x = 1/3 and y = -7/4

Write the answer in simplest form

Answers

Given:
3x + y
Substitute the variables for x = 1/3 and y = -7/4:
3 · 1/3 + -7/4
Multiply 3 by 1/3:
1 + -7/4
Add -7/4 to 1:
-3/4
Final answer:

The expression 3x + y simplifies to -3/4 when x equals 1/3 and y equals -7/4.

Explanation:

To evaluate the expression 3x + y when x = 1/3 and y = -7/4, we simply substitute these values into the expression.

So 3x + y becomes 3*(1/3) - 7/4, which simplifies to 1 - 7/4.

To simplify this further, we convert 1 (which is the same as 4/4) and -7/4 to have the same denominator (which is 4). So, 4/4 - 7/4 equals -3/4.

So, the simplest form of 3x + y when x = 1/3 and y = -7/4 is -3/4.

What is 10.49 seconds rounded to the nearest second

Answers

10 seconds... You just have to leave the first two numbers before the point. :) If a number is bigger after the point like for example 10.59 the answer would be 11 because it can be rounded by the 5. :)



Given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

Recall:

When rounding a number, if the number that comes before it is 5, 6 and up to 9, you round the number up. i.e. 57 to the nearest ten would be rounded up to 60.

When rounding a number, if the number that comes before it is from 4 below, you round the number down. i.e. 54 to the nearest ten is 50.

Thus:

Given 10.49 seconds, we want to round the number to the nearest second.

We need to round it down.

Therefore:

10.49 to nearest seconds = 10 secs.

In summary, given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

At one time, the Texas Junior College Teachers Association annual conference was held in Austin. At that time a taxi ride in Austin was $1.15 for the first 1/5 of a mile and $0.35 for each additional 1/5 of a mile. If the distance from one of the convention hotels to the airport is 8.5 miles, how much will it cost to take at taxi from that hotel to the airport? (Round your answer to the nearest cent.)

Answers

$6.75 would be your answer.

To calculate the taxi fare, we determine the cost for the first 1/5 mile at $1.15, and then add the cost for the remaining increments at $0.35 each. The total fare comes to $15.68 when rounded to the nearest cent.

To calculate the cost of a taxi ride in Austin from one of the convention hotels to the airport for an 8.5-mile distance, let's break it down step by step:

The initial fare covers the first 1/5 mile and costs $1.15.Since the total trip is 8.5 miles, we need to find out how much the remaining 8.3 miles (8.5 miles - 1/5 mile) will cost at $0.35 per each additional 1/5 mile.To find the number of 1/5 mile increments in 8.3 miles, we divide 8.3 by 1/5, which equals 41.5 increments.Now we multiply the number of increments (41.5) by the cost per increment ($0.35), which equals $14.525.Adding the initial fare of $1.15 to $14.525 gives us the total cost of the taxi ride, which is $15.675.Finally, we round $15.675 to the nearest cent to get $15.68 as the total cost of the ride.

Therefore, the taxi fare from the hotel to the airport will be $15.68.

This year, the hotel served 1,133.2 gallons of orange juice. What is the percent of increase in the amount of orange juice served yearly? Round your answer to the nearest tenth of a percent.

Answers

Final answer:

The amount of orange juice served by Sleepwell Hotel increased approximately by 71.7% from last year.

Explanation:

The subject of this question is Mathematics and it deals with the concept of percentage increase. To calculate the percent of increase in the amount of orange juice served yearly by Sleepwell Hotel, we need to keep in mind that the formula to calculate percentage increase is:

(New Amount - Original Amount)/Original Amount * 100

In the given problem, the original amount is 660 gallons (the amount of orange juice served last year) and the new amount is 1133.2 gallons (the amount served this year). Inserting these values into the formula gives us:

(1133.2 - 660) / 660 * 100

After performing the arithmetic, we find that the percent increase of orange juice served by Sleepwell Hotel is approximately 71.7%.
