At a company picnic, 1/2 of the people are employees 2/5 are employees' spouses. What percent are neither?

1 answer:

5 0

First, you want to find a common denominator. The easiest way to do this is to multiple the two denominators together. A common denominator between these two fractions is 10. Two fifths times 2 is 4/10. 1/2 times 5 is 5/10. Add these two fractions together. 4/10+5/10= 9/10. That means 9/10 of the people are employees or their spouses. Now, 10/10 is one whole. You want to subtract 10/10-9/10. Your answer would be 1/10 of the people are now. Now to get your answer to a percent you have to divide 1 by 10. By doing this you get 0.1. Move the decimal 2 places to the right to get 10% of people are not an employee or spouse. Hope this helped!

Answer:

a) y=3x-11

b) y=-1/3x-1

Step-by-step explanation:

First find the slope of the line

rise/run

rise is 3

run is 1

so slope is 3

since this line is parallel to "a", the slope of "a" will also be 3

the equation of a will be

y-y1=3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)

y-(-2)=3(x-3)

y+2=3x-9

y=3x-9-2

y=3x-11

since this line is perpendicular to "b", the slope of "b" will also be reciprocal negative , -1/3

y-y1=-1/3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)

y-(-2)=-1/3(x-3)

y+2=-1/3x+1

y=-1/3x+1-2

y=-1/3x-1

1. Which are true of x = log10 31,500? Select all that apply.

ziro4ka [17]

Given:

$x=\log_{10}31,500$

To find:

Select the true statements from the given options about the given value.

Solution:

We have,

$x=\log_{10}31,500$

It can be written as

$x=\log_{10}(2^23^25^37)$

$x=\log_{10}(2^2)+\log_{10}(3^2)+\log_{10}(5^3)+\log_{10}(7)$ $[\because \log(ab)=\log a+\log b]$

$x=2\log_{10}2+2\log_{10}3+3\log_{10}5+\log_{10}(7)$

$x=2\left(0.30105\right)+2\left(0.47712\right)+3\left(0.69897\right)+0.8451$

$x=4.49835$

Clearly, the value of x lies between 4 and 5. So, $x>4$ and $x$ .

Therefore, the correct options are C and D.
