Sergei estimated 149% of 67 by performing the following steps. which statement is true?
(70)(150%)
- (70)(100% + 50%)
- (70)(100%) + (70)(50%)
- (70)(1)+ (70) )
- 70+35
- 105
the estimate is less than the actual answer because the percent and the number were both rounded down.
the estimate is less than the actual answer because the percent and the number were both rounded up.
the estimate is greater than the actual answer because the percent and the number were both rounded down.
the estimate is greater than the actual answer because the percent and the number were both rounded up.

Last option.

Step-by-step explanation:

In order to estimate the percent "n" of a number"x", you need easy numbers to work with, therefore you can round  "n" and "x" up or down; but it is important to remember that this estimation does not give you an exact value.

You can observe that Sergei's first step was to round 149% and 67 up, getting this result:

To verify if this estimate is less or greater than the actual answer, we can find the actual answer. This is:

Therefore, we can conclude that the estimate is greater than the actual answer because the percent and the number were both rounded up.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)
