Answer 1

Answer:

Answer:

im going to guess you didn't mean 1.240 miles but 1,240 miles

so we need to find how far they went each day so

1240/3=413 1/3 miles a day

Hope This Helps!!!

How can the additive inverse be used to evaluate the problem below? –3 – (–6)
Because 3 + (–6) is an equivalent expression, the answer is –3.
Because 3 + (–6) is an equivalent expression, the answer is 3.
Because –3 + 6 is an equivalent expression, the answer is –3.
Because –3 + 6 is an equivalent expression, the answer is 3.

Answers

Answer: Because –3 + 6 is an equivalent expression, the answer is 3.

Step-by-step explanation:

We know that the additive inverse property says that the additive inverse of any arbitrary number x is a number which when added to x results 0.

For any real number, it generally reverses its sign.

i.e. Additive inverse of x = -x such that x+(-x)=x-x=0

The given problem : $-3-(-6)$

Using additive inverse property, the additive inverse of $-6=6$

$\Rightarrow\ -3-(-6)=-3+6\n=6+(-3)...............................\text{[Commutative property]}\n=6-3\n=3$

addative invesre means adding the invese is same as subtracting the other (???)
confusing

-3-(-6)=-3+6=3

Two of your friends, Matt and Karen, both run to you to settle a dispute. They were working on a math problem, and got different answers. Wisely, you decide to look at their work to see if you can spot the source of confusion.Matt

so in matt's equation, he made a mistake in the a transision from line 2 to line 3
in line 2: -4(-2)2
in line 3: -4(4)
the mistake is that -2 times 2 is not equal +4 it is equal to -4
also from lines 5 to 6 he made a mistake in order of opperations (mulit division then addition and subtract)
line 5: -10+30/5
line 6: 20/5

so he first subtracted 10 then divided, he should have divided then subtracted
so the equation should have equaled

Karen used the correct (-) times (+) property and the order of operations
so Karen is correct and Matt is wrong.

Karen is correct. (-2)2 is -4, not 4 in Matt's answer. Also, Karens, order of operations on the 4th line is correct. She does her division first, and Matt completes his subtraction first. PEMDAS, parenthesis, exponents, multiplication, division, addition, subtraction.

The area of a circle of radius r is given by A=\pi r^2A=πr 2 and its circumference is given by C=2\pi rC=2πr. At a certain point in time, the radius of the circle is r=8r=8 inches and the area of the circle is changing at a rate of \frac{dY}{dt}=\pi\sqrt{2} dt dA =π 2 square inches per second. How fast is the radius of the circle changing at this time

Answers

Answer:

Step-by-step explanation:

If I'm understanding this correctly, your problem is as follows:

The area of a circle is given by the formula

$A=\pi r^2$

The area of the circle is changing at a rate of $(dA)/(dt)=√(2)\pi$ . Find the rate of change of the radius, $(dr)/(dt)$ , when r = 8.

Assuming that is what you are asking, we will begin by finding the derivative of the area of a circle using implicit differentiation.

$(dA)/(dt)=\pi2r(dr)/(dt)$

Filling in what we have:

$√(2)\pi=\pi(2)(8)(dr)/(dt)$ which simplifies a bit to

$√(2)\pi=16\pi(dr)/(dt)$

Divide both sides by 16π to get:

$(√(2)\pi )/(16\pi)=(dr)/(dt)$

The π's cancel leaving the rate of change of the radius as

$(dr)/(dt)=.0883883476$ inches per second

What fraction has a decimal value between 1/2 and 3/4

Answers

To find the decimal value, we must convert 1/2 and 3/4 into decimal.
1/2=0.5
3/4=0.75
Now we just have choose a random decimal in between the decimal.
Let's choose 0.6
Now we have to convert the decimal into a fraction. So we'll multiply the decimal by100.
0.6×100=60
Then we make the 60 into a fractions. 60/100
Then we'll simply the fraction. 60/100÷10=6/10÷2=3/5
There you go. You have your answer.

Answers

The answer is 12 in.²

A = (1/2)(b)(h)
A = (1/2)(4 in)(6 in)
A = 12 in^2
