Round 1.0649 to the nearest thousandth
ira [324]
1.0649 to the nearest thousandths is 1.065

You could get this by finding where the thousandths place is, which is the third number.
Now, look at the number to the right. 
If it's 5 or higher, round up. 
If it's 4 or lower, round down.

Since it is 9, we round up.
The 4 turns into a 5.

So, 1.065

Hope I helped!

The variable z is directly proportional to x, and inversely proportional to y. When x is 4 and y is 13, z has the value 1.230769
Talja [164]

Answer:

Step-by-step explanation:

1.2307692307692.

The first step is to find the proportionality constant.

The formula is

z = kx/y

1.2307692307692 = k * 4/13          Multiply both sides by 13

1.2307692307692 * 13 = 4k

16 = 4*k                                            Divide by 4

k = 16/4

k = 4

=================================

z = k*x/y

x = 9

y = 20

k = 4

z = 4 *9/20

z = 36/20

z = 1.8
