Answer:

True

Step-by-step explanation:

so first u can add the subtract the fractions ⅝-2/8 is ⅜.Then, we do 5-3 is 2. Next, we add the whole number(2) to the fraction (⅜) which is 2⅜

This is dimensional analysis!!

Before we answer the question we must first:1. Assess what we have so far.2. Know what we need to find.3. Solve.4. Conclude.
Step 1: What we have so far.*Price of a ream of paper = $4.00
*No. of sheets of paper in a ream = 500pcs.
*A sheet of paper weighs = 0.50oz
Step 2: What we need to find.*The price of 1lb (pound) of paper = ?
Step 3: Solve.*1lb = 16oz
Know how many papers are there in 1lb:
*1lb = 16oz
*1 sheet of paper = 0.50oz
*16oz of paper = 32 pcs of paper.
Because 16 divided by 0.50 is = 32.
*1lb of paper = 32 pcs of paper.

Know how the weight of a ream of paper:
*Ream of paper has 500 papers.
*32 papers = 1lb
500 divided by 32 = 15.625
*Weight of a ream is 15.625lb.

Know how much a pound (lb) of paper is:
*A ream of paper costs $4.00.
*A ream of paper weighs 15.625lb.
4.00 divided by 15.625 = 0.256
*Cost per pound (lb) of paper = $0.256 or $0.26 or 26 cents.

Step 4: Conclusion.After successfully doing the steps above, we can now conclude that the cost per pound of paper is $0.256 or $0.26 or 26 cents.

Please help Ladder question!!

PIT_PIT [208]

Answer:

Step-by-step explanation:

This is a related rates problem from calculus using implicit differentiation. The main equation is going to be Pythagorean's Theorem and then the derivative of that. Pythagorean's Theorem is

$x^2+y^2=c^2$ where c is the hypotenuse and is a constant. Therefore, the derivative of this with respect to time, and using implicit differentiation is

$2x\frac{dx}{dt}+2y\frac{dy}{dt}=0$ and dividing everything by 2 to simplify a bit:

$x\frac{dx}{dt}+y\frac{dy}{dt}=0$ . Upon analyzing that equation, it looks like we need values for x, y, $\frac{dx}{dt}$ , and $\frac{dy}{dt}$ . And here's what we were given:

$\theta=45$ and $\frac{dx}{dt}=.5$ In the greater realm of things, that's nothing at all.

BUT we can use the right triangle and the angle we were given to find both x and y. The problem we are looking to solve is to

Find $\frac{dy}{dt}$ at the instant that $\frac{dx}{dt}$ = .5.

Solving for x and y:

$tan45=\frac{x}{6}$ and

6tan45 = x ( and since this is a 45-45-90 triangle, y = x):

$6(\frac{\sqrt{2} }{2})=x=y$ so

$x=y=3\sqrt{2}$ and now we can fill in our derivative. Remember the derivative was found to be

$x\frac{dx}{dt}+y\frac{dy}{dt}=0$ so

$3\sqrt{2}(\frac{1}{2})+3\sqrt{2}\frac{dy}{dt}=0$ and

$\frac{3\sqrt{2} }{2}+3\sqrt{2} \frac{dy}{dt}=0$ and

$3\sqrt{2}\frac{dy}{dt}=-\frac{3\sqrt{2} }{2}$ and multiplying by the reciprocal of the left gives us:

$\frac{dy}{dt}=-\frac{3\sqrt{2} }{2}(\frac{1}{3\sqrt{2} })$ so

$\frac{dy}{dt}=-\frac{1}{2}\frac{m}{s}$

Select the point that satisfies

Vika [28.1K]

Answer:

A. (5,5)

Step-by-step explanation:

Plug in (5,5) for the x and y values according to the ordered pair. In this case the equation should turn out like this :5 ≤ 5²- 4(5) + 2

Simplify the equation : 5 ≤ 25 - 20 + 2
5 ≤ 7
A is the answer because it satisfies the inequality as 5 is less than or equal to seven. Though, in this case it is just less than, but not equal to.
