There will be two squares.

Think about it: The shorter side is 3.5 feet. The longer side is 7 feet. If he cuts it in half on the longer side, he's taking the length of that longer side, and dividing it by 2. 7/2=3.5.

So, you'd have two squares, both with a length and width of 3.5 feet.

Use properties of real numbers to rewrite the expression. (3/5)(5/3)
NeX [460]
Given that (3/5) and (5/3) are real numbers, using closure property of multiplication which states that the product of any two real numbers is a real number, then:
3/5*5/3=1
hence we conclude that 1 s a real number.

Y is directly proportional to (x-4) when x=16, y=3 find y in terms of x
Paha777 [63]

Answer:

y = ¼(x-4)

Step-by-step explanation:

Before solving the question, let's look at one example,

  • A is directly proportional to B means A∝B which also means A=kB where k is a constant.

In this case, y is directly proportional to (x-4) means that y∝(x-4) which can also mean that y=k(x-4).

Hence, to find the value of k, substitute x=16, y=3 into y=k(x-4),

3=k(16-4)

k=3/12

k=1/4

After that, substitute the k value into the equation,

<h3>y = ¼(x-4)</h3>

The surface area of the rectangular prism below is 286in2. Find the height.
Rudiy27

Answer: 7in

Step-by-step explanation:

Formula: A=2(wl+hl+hw)

Solve for h;

Let's begin by dividing by 2.

\frac{A}{2}=wl+hl+hw

Subtract wl because it's the only term that doesn't have h.

\frac{A}{2}-wl=hl+hw

Plug your values into the formula.

\frac{286in^2}{2}-(5in)(9in) =h(9in)+h(5in)\\143in^2-45in^2=9inh+5inh\\98in^2=14inh

Divide by 14 to isolate h.

\frac{98in^2}{14in}=h

7in=h
