Answer:

$\text{D.}\quad d=\dfrac{206-8(10)}{7}$

Step-by-step explanation:

The total length of the space between rungs is the overall length less the width of 8 rungs, so is 206 -8(10). That space is divided into 7 equal parts, as shown by the equation in choice D.

_____

Choice A looks similar, but is not. In that equation, only the term 8(10) is divided by 7. You want the difference to be divided by 7, so must have a grouping symbol of some kind. Choice D uses the division bar to group the terms of the numerator. Parentheses would work, too, as in ...

d = (206 -8(10))÷7

but without them, the equation is incorrect.

Answer:

230 2/3 ft

Step-by-step explanation:

60 5/6 + 54 1/3 + 59 1/3 +56 1/6

5/6+1/3+1/3+1/6=

Put them into same denominator times 1/3 by 2

5/6+2/6+2/6+1/6= 10/6 (this is improper fraction, simplify and then turn it into mixed)

10/6= 5/3 = 1 2/3

60+54+59+56= 229 +1= 230 and the 2/3 before makes it

230 2/3 ft

15-4 = 11

11 x 2 = 22

22 + 2/3 = 68/3

The population of a country was estimated to be 1.114 x 10^8. On this day, the population of the world was 3.853 x 10^9.

Lelechka [254]

Step-by-step explanation:

To find how many people lived outside of the country we subtract:

3.853 × $10^{9}$ - 1.114 × $10^{8}$ = 3.7146 ×

To find the percentage of people living inside the country, we divide: $\frac{1.114 x10^{8}}{3.853 x10^{9}} =2.8913x10^{-2}$ percent or 2.89%. Which is extremely small.
