Answer:

1000

Step-by-step explanation:

Doing this on a calculator yields 1000.

Alternatively, do part or all of the problem in your head:

Rewrite 42 ÷____= 0.042 as

------------

0.042

and move the decimal points 3 place to the right:

42 becomes 42000, and 0.042 becomes 42. Thus, we have:

42000

------------ = 1000

ANSWER AND EXPLAIN I’LL MARK BRAINLIEST PLEASE ILL MARK BRAINLIEST

Answer:

160 meters

Step-by-step explanation:

Before I begin, note that distance = rate * time (or d = r * t)

To solve this problem, we need to find what point these two people have the same distance. (so Janiyah covers the same distance as Connor)

So, let's set the time that Janiyah takes as x (in seconds). So, he covers

d = r * t, or 8x meters

Then, Connor's equation would be

d = r * t

d = 5x + 60 (because he got a 60 meter headstart)

Because d is the same in both equations, to solve for the amount of time they run:

8x = 5x + 60

Subtract 5x from both sides.

3x = 60

x = 20

Then, to find Janiyah's distance (you can also use Connors because the two distances are equal), put x = 20 into 8x

8x = 8 * 20 = 160

So, Janiyah ran 160 meters.

Just in case, let's check if this is correct. Connor's distance equals Janiyah's, so

5x + 60 = 160

5 * 20 + 60 = 160

100 + 60 = 160

160 = 160

True.

So, the answers are correct.

I hope this helps! Feel free to ask any questions!

How to solve this Pythagorean Theorem.

miskamm [114]

Oh, this is really easy!
Okay so the formula for the pythagorean theorem is a²+b²=c²
So it doesnt really matter whats a or b
So take 21²+15²=c²
That ends up being 441+225=c²
so next take 441+225 and that equals 666 then you have to find the square root so the square root of 666 is 25.81

S the answer is 25.81

Need help on this question

Shalnov [3]

It won't go all the way up to 50, but to 49 at stage 13.
All you need to do is keep adding 3 for each stage until you get to 50, but in this case or problem, 49.
I hope this helps.=^D
