Step-by-step explanation:

Given the choices of answers we have to consider that:

The cloth is cut from the square = Area of circle

Area of circle = π r² = 3.14 * 21² = 1,384.74 in²

Answer:

1/6 < x

Step-by-step explanation:

–2(8x – 4) < 2x + 5

Distribute

-16x +8 < 2x+5

Add 16x to each side

-16x+8+16x < 2x+16x+5

8<18x+5

Subtract 5 from each side

8-5 < 18x+5-5

3 <18x

Divide each side by 18

3/18 <18x/18

1/6 < x

Answer:

I think e no answer is correct

Answer:

-10

Step-by-step explanation:

The reason why I believe the answer to your question is -10 is because inequality represents the difference in size, degree, circumstances, etc.; lack of equality. So I had to find the difference between -5 and 5, and -5 minus 5 is -10.

Also if this helps, it would be nice if you gave brainlest :)

Answer:

72  minutes until they play again

Step-by-step explanation:

18+18+18+18=72

24+24+24=72

Answer:  72 minutes

======================================================

Explanation:

The GCF of 18 and 24 is 6, since this is the largest factor shared between the two numbers

To find the LCM, we'll involve the GCF. The LCM of two numbers x and y is found by multiplying them, and then dividing over the GCF of them.

LCM of x and y = (x*y)/(GCF of x and y)

LCM of 18 and 24 = (18*24)/6

LCM of 18 and 24 = 432/6

LCM of 18 and 24 = 72

-----------

To help confirm this, we can list out the multiples of each

We see that 72 is the lowest common multiple. This is the final answer because each station will play the same song 72 minutes apart.

The stations play the same song at 3 PM. Then 72 minutes later (4:12 PM), the same song is played again on both stations at the same time. Then at 5:24 PM, another 72 minute gap, is when the same song is played again at the same time. And so on.

----------

Side note: 72 minutes = 60 min + 12 min = 1 hr, 12 min

Answer:

(x + 4)(x + 3)

Step-by-step explanation:

x² + 7x + 12 = 0

~Rewrite

(4x + 12) + (x² + 3x)

~Factor out 4 and x

4(x + 3) + x(x + 3)

~Factor out x + 3

(x + 4)(x + 3)

Best of Luck!

Step-by-step explanation:

from what I understand this should be the answer:

x. y

12. 7. Because y=x-5 and 7=12-5

30. 25 Because 25=30-5

15. 10 Because 10=15-5

Answer:

10

Answer:

$18.75 is the cost for 1 month of gameplay.

Step-by-step explanation:

2 software packages in total

Unit price for software package is $50, and since there are two packages, $50x2=$100

Now, we know that the total amount of money that the software cost was $100, we can do 250-100=150

150 is how much they spent for 8 months of gameplay. (2+6=8)

To find how much 1 month of gameplay costs, we need to do 150/8 which is equivalent to $18.75

Answer:

x = -46.5

x + 1 = -45.5

Step-by-step explanation:

x + x + 1 = -92

2x + 1 = -92

      -1       -1

------------------

   2x = -93

   ----     ----

    2        2

   x = -46.5

x + 1

(-46.5) + 1

-45.5

Answer:

No solution

Step-by-step explanation:

We can set up an equation where x is the integer and x+1 is the next one

x+x+1=-92

2x+1=-92

2x/2=-93/2

x=-46.5

-46.5+1=-45.5

The problem is that integers do no include decimals so there is no possible whole number. This problem would be possible if it was consecutive odd integers.

Answer for number 4:

4. It will take them 3.5 hours on the fourth day.

Alright, so this is a multistep problem.

1. We need to calculate how many miles they have already traveled.

In order to do that, we multiply the number of hours by the average speed on each day.

- On day 1, they drove 5 hours at an average of 70 mph. 5 * 70 = 350, so they drove 350 miles on the first day.

- On day 2, they drove 7 hours at an average of 65 mph. 7 * 65 = 455, so they drove 455 miles on the second day.

- 350 miles + 455 miles = 805 miles, so they've driven 805 miles so far.

2. We need to figure out how far they have left to travel.

They started out with 1,050 miles, so they've got 245 miles left. 1,050 - 805 = 245.

3. We need to figure out how many hours they've got left to drive.

On the third day, they drive at an average speed of 70 mph, and they've got 245 miles left. to find the amount of time they need to drive, we divide the distance by the speed.

245 miles ÷ 70 mph = 3.5 hours. Therefore, it will take them 3.5 hours to reach their friend's home.

Answer For Number 5:

10 gallons of water will leak out in 30 hours.

This question involves unit rates.

1. We need to figure out how much water leaks out per hour.

- Since 7 gallons of water will leak out in 21 hours, we divide the amount of water by the amount of time it took for it to leak out. The answer will be how much water leaks out in an hour.

- 7 gallons ÷ 21 hours = 1/3 gallon of water. Now we have our unit rate. Every hour, 1/3 gallon of water leaks out.

2. We need to figure out how much water will leak out in 30 hours.

- Since we know how much water leaks out in 1 hour, we can easily figure out how much water leaks out in 30 hours. All we need to do is multiply how much water leaks out in one hour by 30!

- 1/3 gallon * 30 hours = 10 gallons of water.

Therefore, 10 gallons of water will leak out in 30 hours.

I hope this helps!

Answer:

a+b+c=40

Step-by-step explanation:

Answer:

three solutions:  {-3, -3, 0}

Step-by-step explanation:

This polynomial has already been factored, and the factors are x, x + 3 and x = +3.  To solve this equation, set each of the factors equal to zero separately and solve each of the resulting equations:

x = 0 is a solution; the given equation equals zero when x = 0.

The next factor is x + 3; setting this equal to 0 yields the solution x = -3.

The last factor is x + 3; x = -3 is the third solution.

In summary, (x + 3)(x = 3) = 0 has two solutions; we call them "repeated roots."    x(x + 3)(x = 3) = 0 has three solutions:  {-3, -3, 0} of which two are "repeated."

Answer:

The radius is already given, which is 6 in.

Diameter is equal to 2 times the radius (2x6), which is 12 in.

Finally, circumference is equal to 3.14 times the diameter, which is 37.68 in.

Let me know if this helps!

6.28 * 6 : 37.68

radius is the length of half the circle. and diameter is always double the radius.
