34699 to nearest ten thousand
xz_007 [3.2K]

Ones place: 9

Tens place: 9

Hundreds place: 6

Thousands place: 4

Ten thousands place: 3

Which is 34,699

Now that we know 3 is in the ten thousand's place.

So then go from 3, and jump too 4. If the number is higher then 5, the 3 would become a 4. If the number is lower then 5, 4 would become a 0 and so will the rest of the number's too the right.

34,699 ---> 30,000

That being said, the answer is 30,000!

I hope this help's! :)

Solve the equation kx+9=7 for x
Alika [10]

Answer:

x=-2/k

Step-by-step explanation:

To solve you need to make x on one side while the other variables or numbers on the other.

First, you need to move the 9 to the other side by subtracting 9 from both sides: kx+9-9=7-9

Simplify: kx=-2

Now you need to divide by k into both sides in order to eliminate the k on kx:

x=-2/k

Answer: x=-2/k

Hope this helps!

Mandarinka [93]
You need to solve this for h(t)=0

<span>-16t^2-30t+124=0

This has two solutions, one is negative that does not make sense as time cannot be negative. 
The positive solution is t=2

So the interval where it is in the air is [0;2)
