There's an infinite amount of numbers that round to 8.21 when rounded to the nearest hundredth, for example:
8.211
8.209
8.214
8.21145683204
etc...
Just pick whichever two numbers you like :)
Answer:
speed of light is 3 x meters per second.
Step-by-step explanation:
Given : The speed of light is 3 x kilometers per second.
To find : What is that in standard form.
Solution : We have given 3 x kilometers per second.
First we convert it in to meter per sec.
We can write
3 x = 300000 kilometer per second .
We know that 1 km = 1000 meter.
Then 300000000 meter per second
Now, 3 x meter per second.
Therefore, speed of light is 3 x meters per second.
Answer:
The answer is B
Step-by-step explanation: After solving this equation using y=mx+b
I got y=-4x+7
So they give us the slope which is negative 4
so you would throw in the x coordinate with the slope and multiply to get y=-12+7
then you would use the y coordinate to substitute the Y
-5=-12+7
i add twelve on both sides and end up with the y intercept being 7]
so I add them into the equation and got y=-4x+7
Answer:
C
Step-by-step explanation:
If we solve 10f-5f+8+69+4, We get 5f+81 (put in comments if you want a step by step explanation on how i solved this).
Let's try to solve each of the options.
A) 15f + 14g + 4
It would not be option A because there isn't a variable such as g in the expression.
B) 15f + 8 + 10g
Not this as well.
C) 5f + 69 + 12
5f+ 81
This one is correct because the expression also equals 5f+81
D) 5f + 149 +4
5f+ 153
D would be wrong as well
Hope this helps! <3
