Answer:

8 feet

Step-by-step explanation:

In a rectangle

length (L) = 12 feet

perimeter (p) = 40 feet

width (b) = ?

We know

p = 2(L + b)

40 = 2 ( 12 + b)

40/2 = 12 + b

20 = 12 + b

b = 20 - 12

b = 8 feet

Answer:

12 feet

Step-by-step explanation:

Perimeter of rectangle = 2( l + b )

40 = 2( 12 + b )

40 = 24 + 2b

40 - 24 / 2 = b

12 feet = b (width)

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

9

Step-by-step explanation:

To find the answer, first convert 4 ft. to inches. 4 ft.= 48 in. Now, you divide 48÷5. 48÷5=9 3/5, or 9.6, but you can't cut a sixth of a board. Therefore, the answer is 9.

Hope this helps!

Answer: 9 pieces

Step-by-step explanation:

First, convert 4 feet to inches. 4 ft = 48 in.

Then, divide 48 in by 5 in. 48/5 is 9.6 in

But since you can't cut the board into sixths the answer is 9.

We can start by using the information given to set up an equation that represents the situation. Let x be the starting altitude.

We know that:

   The starting altitude + the altitude gained = the current altitude

   The current altitude is 285 feet

   The altitude gained is 296 feet

So, we can write an equation to represent this situation as:

x + 296 = 285

To find the starting altitude, we need to solve for x. To do this, we'll subtract 296 from both sides of the equation:

x + 296 - 296 = 285 - 296

x = -11

However, an altitude of -11 feet is not possible. We can infer that the starting altitude is actually 0 feet.

So the starting altitude is x=0 feet

Answer:

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Step-by-step explanation:

The given equation is:

4 = u + at

where u = 17, a = 4, and t = 8.

Substituting the given values, we get:

4 = 17 + 4(8)

Simplifying the right-hand side:

4 = 17 + 32

Combining like terms:

4 = 49

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Answer:

p= 8/9

Step-by-step explanation:

4(-3p+6)-5p=10p

-12p+24-5p=10p

-12p+24-5p=10p

-17p+24=10p

-17p+24-24=10p-24

-17p=10p-24

17p-10p=10p-24-10p

-27p=-24

-27p/-27=-24/-27

p=8/9

Hope this Helps!

p=8/9

(Chronological Steps)

-4(-3p+6)-5p=10p

-12p-24-5p=10p

-17p+24-10p

-17p+24-24=10p-24

-17p=10p-24

-17p-10p=10p-24-10p

-27p=-24 (since negative and negative equal positive, p is positive)

p=24/27

p=8/9 (final answer)

Answer: 22.5 pounds

Step-by-step explanation:

The computation of the weight of the block of gel is shown below:

As we know that

Volume = (length) (width) (height)

= (20) (6 ) (6)

= 720 cubic inches 

Now we have to convert into cubic foot

As we know that

1 ft = 12 inches

So 1ft^3 = 12 inches^3

= 1728 inches ^3
Now

= 720 × 1 cubic foot ÷ 1728 cubic inches

= 5 ÷ 12

Now the weight is = 54 × 5 ÷ 12= 

22.5 pounds

Step-by-step explanation:

If 10 students are watching a 2 hour and 42 minute long movie.  6 students are watching the second movie.

We can use proportions to solve this problem. Let's start by finding the total number of minutes in the first movie:

M = 2 hours x 60 minutes/hour + 42 minutes = 120 minutes + 42 minutes = 162 minutes

Now, we can set up a proportion to find the number of students watching the second movie:

S/M = S'/M'

where S is the number of students watching the first movie (which we know is 10), M is the number of minutes in the first movie (162), S' is the number of students watching the second movie (which we want to find), and M' is the number of minutes in the second movie (91).

Substituting in the values we know and solving for S', we get:

10/162 = S'/91

S' = (10 x 91) / 162 = 5.62

Since we can't have a fractional part of a student, we need to round our answer to the nearest whole number. Therefore, approximately 6 students are watching the second movie.

Step-by-step explanation:

The length of the picture frame is 6 inches and the width is 10 inches.

The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.

Let's represent the width of the picture frame "w" and the length of the picture frame "l". We know that the width is 4 inches longer than the length, so we can write the equation:

w = l + 4

The perimeter of the picture frame is the sum of all four sides, so we can write the equation:

2w + 2l = 44

We can substitute the first equation into the second equation to get:

2(l + 4) + 2l = 44

This simplifies to:

4l + 8 + 2l = 44

Combining like terms, we get:

6l + 8 = 44

Subtracting 8 from both sides, we get:

6l = 36

Dividing both sides by 6, we get:

l = 6

Substituting this value back into the equation w = l + 4, we get:

w = 6 + 4

Simplifying, we get:

w = 10

Thus, the picture frame is 6 inches in length and 10 inches in width.
