Find the sum of 362+265.explain why you did or did not regroup.

Answers

Answer 1

Answer: 362+265=627.You have to regroup because when you add 2 numbers that equal more then 9 they will need extra space so you put it at the top

Answer 2

Answer: EDIT:
Order of operations doesn't matter in addition. So you can add them in any order.

I recently took a test in my Algebra 1 class. This was on the test (that I most likely failed)and it said something about vertical motion. The problem is below. Try to solve it, please! Thanks!2=-t^2+4+5

Answers

OK.    2 = -t² + 4t + 5

Subtract 2 from each side: 0 = -t² + 4t + 3

Multiply the right side by -1 : 0 = t² - 4t - 3

Unfortunately, this can't be factored. The only other way I know
to find the solutions to a quadratic equation is with the use of the
quadratic formula. When you do that, you get these solutions:

   t = 2 + √7 = about 4.65
and
   t = 2 - √7 = about -0.65 .

If this equation comes from a problem that involves real people throwing
real things into the air and making vertical motion, then you want only the
positive solution.

Each cube inside the rectangular prism has no edge length of 3/4 inch what is the volume of the rectangular prism

Answers

Answer: Volume = 81 cubic inches

Step-by-step explanation:

Given that each cube has length = 3/4 inches

The height H = 3/4 × 8 = 6 inches

Where 8 = number of cubes

The length L = 3/4 × 6 = 4.5 inches

Where 6 = number of cubes

The width W = 3/4 × 4 = 3 inches

Where 3 = number of cubes

The volume V = L × W × H

Substitute all the parameters into the formula

V = 4.5 × 3 × 6 = 81 cubic inches

Therefore, the volume of the rectangular prism is 81 cubic inches

Answer:

Answer: Volume = 81 cubic inches

Step-by-step explanation:

Given that each cube has length = 3/4 inches

The height H = 3/4 × 8 = 6 inches

Where 8 = number of cubes

The length L = 3/4 × 6 = 4.5 inches

Where 6 = number of cubes

The width W = 3/4 × 4 = 3 inches

Where 3 = number of cubes

The volume V = L × W × H

Substitute all the parameters into the formula

V = 4.5 × 3 × 6 = 81 cubic inches

Therefore, the volume of the rectangular prism is 81 cubic inches

Farmer Ed has 300meters of fencing, and wants to enclose a rectangular plot that borders on a river. If Farmer Ed does not fence the side along the river, find the length and width of the plot that will maximize the area. What is the largest area that can be enclosed?Width
Length
Largest area:

Answers

The area of the farm is the amount of space on the farm.

The width of the farm is 150 meters
The length is 75 meters
The largest area is 11250 square meters

Given

$P = 300m$ --- the perimeter

$L \to Length$

$W \to Width$

Because one side of the farm is a river, the perimeter is calculated as:

$P = 2L + W$

So, we have:

$2L + W=300$

Make W the subject

$W = 300 - 2L$

The area of the farm is:

$A = L * W$

Substitute $W = 300 - 2L$

$A = L * (300 - 2L)$

$A = 300L - 2L^2$

Differentiate, and set the result of the differentiation to 0

$A' = 300 - 4L$

$300 - 4L = 0$

Solve for L

$4L = 300$

Divide by 4

$L =75$

Solve for W

$W = 300 - 2L$

$W = 300 - 2* 75$

$W =150$

Solve for A

$A = L * W$

$A = 75 * 150$

$A = 11250$

Hence,

The width of the farm is 150 meters
The length is 75 meters
The largest area is 11250 square meters

Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose the width is W.

Suppose the length is L.

Total fence is given as 300, so

$L+W+W=300$

$L+2W=300$ ......................(1)

$Area=Length*Width$

$Area=L*W$

Plugging the value of L from equation (1)

$Area=(300-2W)*W$

$Area=300W-2W^2$

For Area to be maximized, derivative of area should be equal to zero.

Means :

$(d)/(dW)Area= 300-4W = 0$

So, $So, W Width = (300)/(4)=75$

So, $L Length=300-2*75=150$

So, Largest area= $75*150=11250$ : Answer

If y varies jointly with x and z and y=13 when x=26 and z=6 find x when y=25 and z=18

Answers

Step-by-step explanation:

as I can see this the answer is

x = 25/78

in decimal

x = 0.320

Final answer:

The problem involves joint variation with variables y, x, and z. After finding the constant of variation, we substitute the given values into the joint variation equation and determine that x = 16.67

Explanation:

First, we establish the equation of joint variation, which in this context is y = kxz, where 'k' is the constant of variation. When y=13, x=26, and z=6, we insert these values into the equation to solve for 'k'. This gives us k = y/(xz) = 13/(26*6) = 0.08333.

Now that we have the constant 'k', we can find the value of 'x' when y=25 and z=18. We rearrange our equation to solve for 'x', resulting in x = y/(kz). Substituting the known values, we get x = 25/(0.08333*18) = 25/1.5 = 16.67. Therefore, if y varies jointly with x and z, and y=25 when z=18, then x = 16.67.
