Suppose you walk 2 miles in 35 minutes. 4. write a proportion to find how far you would walk in an hour if you were to continue
Mrac [35]
Distance traveled in 35 minute = 2 miles.

So distance traveled in one minute = 2/35 (miles/minute)
                                                             = 0.0572 miles / minute.

So distance traveled in one hour  , we can find by multiplying it from 60.Because in one hour there is 60 minute.

SO distance traveled in one hour = 0.0572 * 60 
                                                          = 3.432 miles / hour.

At a speed of 22 revolutions per minute, how long will it take a wheel of radius 10,
Bogdan [553]
Well, if the radius is 10, then the circumference is \frac{2*10*22}7=\frac{440}7
What's the unit? Either way, 22 rev. per minute means each minute you go by 22*\frac{440}7=\frac{9680}7 units per second. Now you got the linear speed, just find out the time by dividing the distance by the speed!
So, what's the unit for the radius?

Alexxx [7]

Answer:

B.

Step-by-step explanation:

So, lets remember a few things first.

#1: The formula for finding the answer is A^2+B^2=C^2

#2: A is the opposite side, B is the adjacent side, and C is the hypotenouse side.

Now lets plug in what we already know, and see if we canf igure out the annswer:

<u>A^2+12^2=13^2</u>

Now I am going to stop us here. This is your equation that will find the answer. In your question, they use x^2, A^2 is a variable you can use instead. But looking at this, answer B and my equation I wrote above are exactly the same.

If you want, here is how I further solved it, this might give you a better grasp on what to do for future problems:

Ok, not  too bad, the A is the unkown value, which is the opposite side.

Now, how do we figure this out? Well, we just need to sovle for A.

To do this, lets clean up our equation by first sqauring all the values(except for the unkown):

A^2+144=169

Ok, that looks better, now lets just subtract the adjeacent side(b), which is 144, from the hypotenouse side(c), which is 169.

This will now look like:

A^2=25(169-144=25)

Ok, just one more step to go. Just square root both sides of the equation, this way, we will get ride of the ^2 on A(opposite side), and get A alone.

(\sqrt{A^2}=A)=(\sqrt{25}=5)

A=5

This is your answer.

It gets cut off but it says ' Write the number marked with an arrow on the number line below as an improper (top-heavy) fraction
Anit [1.1K]

Answer:

1.2

Step-by-step explanation:

it's 1.2 because

the marked parts on the number line represent a fraction of the whole

so in writing this

it will be decimals

and wen the marked lines between 0 and 1 are counted it is 4

so starting each marked line represent 2

so

0.2,0.4,0.6,0.8,1,1.2,1.4,......

so from 1 the next marked part is 1.2

so the answer is <u>1.2</u>
