Answer:

(-9.15)

Step-by-step explanation:

We are given these following vectors:

u = (2,4), v = (-1,-1), w = (7,-2)

What is the vector for 3u + v- 2w in component form?

3u + v - 2w = 3(2,4) + (-1,-1) - 2(7,-2) = (6,12) + (-1,-1) + (-14,4) = (6 - 1 - 14, 12 - 1 + 4) = (-9, 15)

The answer is (-9,15).

Josh wants to determine the number of loaves of bread he can bake using the 13 and one-third cups of flour he has. If each loaf
motikmotik

Answer:

Approximately 4 loaves of bread.

Step-by-step explanation:

Let us get out the total amount of flour that Josh has first of all. This is 13\frac{1}{3} cups of flour.

Each lof requires 3\frac{4}{5} cups of flour. This means that to make a loaf, he will be taking out this quantity of flour from the whole lot.

To get the total number of loaves he can make with this quantity of flour, we will have to divide the total quantity of flour available by the quantity required to make a single loaf.

This will be 13\frac{1}{3} ÷3\frac{4}{5} = 3\frac{29}{57} . This is approximately 4 loaves of bread

2) A salesperson earns commission on the sales that she makes each month.
mixer [17]
Part A
Commission total = Commission 1+ Commission 2
Where
Commision 1 = 5% of first 45000
Commission 2 = 7.5% of the amount left after $5000 is subtracted
thus 
Commision 1 = $5000x.05
                      = $250

Commission 2= $3000 x.075
                        = $225
Commission total = $250+$225
                              = $475
The total commission she earned is $475ion

Part B.
Total sales = Sales with 5% commission+Sales with 7.5% commission
Sales with 5%commission= $5000
Commision At 7.5% = Total commision -Commission with 5%
                           =    $1375-$250
              Sales x.075=  $1125
              Sales with 7.5% commision = $15000
Total sales = $5000+$15000
Total sales = $20000
Total sales for commission of $1375 is $20000
