Answer:

About $241.11

Step-by-step explanation:

So, Karen receives 18.2 cents per paper.

She delivers 124 paper per day.

In other words, on days other than Sunday, she will make a total of:

$18.2(124)=2256.8\text{ cents}$

On Sunday, each paper is sold for $0.70 or 70 cents. She also sells 151 Sunday papers. Thus, on a Sunday, she will make a total of:

$70(151)=10570\text{ cents}$

Therefore, in one week, she will do the first equation six times and the Sunday equation once. Thus, her total pay will be:

$6(2256.8)+10570=24110.8\text{ cents}\approx\$241.11$

a) The halfway number is $\frac{-4.5}{10}$ .

b) The ascending order is $\frac{-1}{2}$ , $\frac{-4.5}{10}$ and $\frac{-2}{5}$ .

Step-by-step explanation:

a)Halfway number is otherwise Middle number.

The halfway number of two numbers = $\frac{sum of two numbers}{2}$ .

The halfway for $\frac{-2}{5}$ and $\frac{-2}{5}$ = $\frac{\frac{-2}{5}+ (\frac{-1}{2})}{2}$ .

= $\frac{-2}{5}+ (\frac{-1}{2})$ .

= $\frac{-4-5}{10}$ .

= $\frac{-9}{10}$ .

∴Halfway = $\frac{\frac{-9}{10} }{2}$ .

= $\frac{-4.5}{10}$

The halfway for $\frac{-2}{5}$ and $\frac{-1}{2}$ = $\frac{-4.5}{10}$ .

b) The ascending order is $\frac{-1}{2}$ , $\frac{-4.5}{10}$ and $\frac{-2}{5}$ .

On a map, the length of a nature trail is 7.2 centimeters. If the scale is 1 centimeter to 25 kilometers, what is the actual len

Lisa [10]

A:b=c:d
7.2:x=1:25. If u see two ratios equal each other, the product of a and d is equal to the product of b and c. This means that (7.2 times 25) is equal to x. This equals 180=x. The actual distance of the trail of 180 km. Hope this helps!
