Bill works for the Stuff It Mailing Service. He receives 25 cents for each document he puts together and prepares for
KATRIN_1 [288]

Answer:

(a)Bill's Total piecework pay =$500

(b)Amount owed by his boss=$26

Step-by-step explanation:

Let the number of documents put together and prepared for mailing by Bill =x

Bill receives 25 Cents=$0.25 for every document

Therefore for x documents, Bill should receive: $0.25x

If Bill prepared 2000 documents for mailing

x=2000

The amount he should receive = $0.25 X 2000 =$500

(a)Bill's Total piecework pay =$500

(b)Amount owed by his boss

=500-474

=$26

Line segments JK and JL in the xy-coordinate plane both have a common endpoint J(-4,11) and midpoints at M, (2, 16) and M2 (-3,5
ohaa [14]

Answer:

12.1

Step-by-step explanation:

We use the formula for the distance between two arbitrary points (x_1,y_1) and (x_2,y_2) in the xy-coordinate plane, that is:

d=\sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}

So, replacing the points M=(2,16) and M_2=(-3,5), we obtain:

d=\sqrt{(2-(-3))^2 + (16-5)^2}\\d=\sqrt{(2+3)^2 + (16-5)^2}\\d=\sqrt{5^2 + 11^2}\\d=\sqrt{146 }=12.083045... \simeq 12.1

that is the answer.

note: observe that we only use the coordinates between the two midpoints and not the point J.

A girl plants 45 flowers in 30 mins. <br> Determine the unit rate.
notka56 [123]
So 45 in 30mins

we ususlly want to make the smallest number equal to one or as close to one as possible so
45/30=3/3 times 15/10
3/3=1
1 times 15/10=15/10
15/10=5/5 times 3/2
5/5=1
1 times 3/2=3/2
3 divided by 2 is 1.5
1.5 flowers per minute
