091 rounded to hundreths place

Zina [86]

There has to be a decimal in order to round to the "hundreths" place. I'm assuming you meant ".091" in which case you would look at the hundreths column, which is a 9. Then to round, you look at the number to the right of the number you're rounding, if it's greater than 5 you round up, less than 5 you stay the same. Since the number to the right is 1, your final answer is ".09"

One estimate of the population of the world on January 1, 2005, is 6,486,915,022. The population is estimated to be increasing a

luda_lava [24]

The answer is <span>8,686,308,783.</span>

To calculate this, we will use the equation for exponential function:
$y=x(r+1) ^{n}$
y - the future population
x - the current population
r - the rate of increasing the population
n - the number of years

It is given:
x = 6,486,915,022
r = 1.4% = 0.014
n = 2026 - 2005 = 21

Therefore:
$y= x(r+1)^{n} =6,486,915,022*(0.014+1) ^{21} = 8,686,308,783$

If y varies inversely as x and y is 2.5 when x is 6, what is y when x is 4? a. 3.75 b. 1.67 c. 0.1 d. 7.5 Please select the best

REY [17]

Because y varies inversely as x, therefore
$y= \frac{k}{x}$
where k = constant.

When x = 6, y = 2.5. Ther efore
$\frac{k}{6} = 2.5$
Cross multiply.
k = 6 x 2.5 = 15

The equation is
$y = \frac{15}{x}$

When x = 4, obtain
$y = \frac{15}{4}= 3.75$

Answer: a. 3.75
