Answer:

A. 80

Step-by-step explanation:

Count the first top half and you get 40 and you will know the bottom half is 40

which altogether is 80 or you can count the blocks one by one or count the blocks on the right side count the top blocks by five across.

V= l*w*h

V= 5*4*4

V= 80

Hope this Helps! :)

Have a nice day! :)

Analyze the following budget, with an income of $750, to determine how much can be spent on food for the month. Month________ Bu

NARA [144]

The phrase "no more than" implies upper limit. The correct choice for food budget is: Option D. No more than $60 can be spent on food.

<h3>How to find the remaining amount after deduction?</h3>

Suppose that you had initial amount as A.

Let you deduce B, C, and D from it.

The remaining amount is obtained by subtraction.

Thus,

Remaining amount = A - (B + C + D) = A - B - C - D

For the given case, the budget left for food is the remaining amount after all the expenses are reduced from the income.

Income = $750

Expenses except food: $20 + $75 + $85 + $260 + $250 = $690

Thus, budget left is $750 - $690 = $60

This remaining budget is left. The person can spent either full of it on food or less than it, but cannot spend more than it as that person doesn't have more than $60 left.

Thus:

Food budget is no more than $60.

Food budget ≤ $60

Thus,

The correct choice for food budget is: Option D. No more than $60 can be spent on food.

Solve the quadratic equation by completing the square.<br> x²–2x-12=0

inn [45]

Answer:

$(x-1)^2-13=0$

$x = \sqrt{13}+1$

Step-by-step explanation:

Completing the square is a method of rewriting a quadratic equation in the standard form such that it is in vertex form. The first step is to group the linear and quadratic terms, then factor out the coefficient of the quadratic term. After doing so, complete the square, add a value such that the linear and quadratic terms form a perfect square trinomial. Do not forget to balance the equation. The final step is to simplify.

$x^2-2x-12=0$

Group,

$(x^2-2x)-12=0$

Complete the square,

$(x^2-2x+1)-12-1=0$

Simplify,

$(x-1)^2-13=0$

Now solve the equation using inverse operations,

$(x-1)^2-13=0\\\\(x-1)^2=13\\\\x-1=\sqrt{13}\\\\x = \sqrt{13}+1$

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. 568 fee

amm1812

<span>First, we write an equation to represent that the fencing lengths add up to 568 feet. we call the side of the fence that has three segments of its length x and the side with only two segments y. We write 3x + 2y = 568. We also know that the area of the rectangle is equal to xy, so area = xy. We put y in terms of x using our first equation and find that y = (568 - 3x)/2. We plug this into our area equation and find that area = (568x - 3x^2)/2. To find the maximum we set the derivative equal to 0 and end up with 0 = 284 - 3x. We solve for x and get 94 and 2/3. We then put that into our first equation to find y = 142. So the dimensions that maximize the area are 94 2/3 x 142.</span>
