Maddie bought 3 2/3 yards of satin ribbon at the craft store. She wanted to make hair bows for the cheer squad. Each bow require

kotegsom [21]

Answer:

Step-by-step explanation:

Given that:

Total yards of satin bought by Maddie = $3\frac{2}{3}$ yards

Number of yards required make one ribbon = $\frac{2}{3}$ yards

To find:

Number of complete bows that can be made ?

Solution:

First of all, let us learn about converting the mixed fraction to fractional form.

Formula:

$a\dfrac{b}{c} = \dfrac{a\times c+b}{c}$

Therefore, total yards of satin bought by Maddie can be written in fractional form as:

$3\dfrac{2}{3} = \dfrac{3\times 3+2}{3} = \dfrac{11}{3}$

One hair bow requires $\frac{2}{3}$ yards of ribbon.

Number of hair bows that can be made, can be found by dividing the total ribbon length by ribbon required for making one hair bow.

Answer is:

$\dfrac{\frac{11}{3}}{\frac{2}{3}}\\\Rightarrow \dfrac{11\times 3}{2\times 3}\\\approx 4$

4 hair bows can be made.

How many five digit numbers can be formed from the digits 1,,3,4,5,6,7 if no digit is repeated

Viktor [21]

To get all possible permutations of these five spaces, we just multiply these numbers (that is, 8∗7∗6∗5∗4=6,720)

There are 6,720 five digit numbers that can be formed from the digits provided given that no digit may be repeated.

Hope that helped!

Please help with parts a,b, and c

Answer:

3000 = n*240 +s*360

1050 = 90n+120s

On this particular day, there are 5 nurses and 5 support staff working

Step-by-step explanation:

Nurses work 240 minutes per day

Support staff work 360 minutes per day

Let n = number of nurses

Let s = number of support staff

a) 3000 minutes are worked

The total number of minutes worked = the number of minutes worked by a nurse per day times the number of nurses plus the number of minutes worked per day by a support staff person times the number of support staff people

3000 = n*240 +s*360

b) earnings per day = 1050

The total number of dollars earned each day= the wages of a nurse per day times the number of nurses each day plus the wages of a support staff person per day times the number of support staff people working each day

1050 = 90n+120s

c) We have 2 equations and 2 unknowns

3000 = n*240 +s*360

1050 = 90n+120s

Divide each equation by 10

300=24n+36s

105 = 9n+12s

Multiply the second equation by -3

-315 = -27n -36s

Add this to the first equation to eliminate s

-315 = -27n -36s

300=24n+36s

---------------------

-15 = -3n

Divide by -3

-15/-3 = -3n/-3

5=n

There are 5 nurses working that day

Now we need to solve for s

105 = 9n+12s

105 = 9(5) +12s

105 = 45+12s

Subtract 45 from each side

105-45 = 45-45 +12s

60 = 12s

Divide by 12

60/12 = 12s/12

5 =s

There are 5 support staff working.

On this particular day, there are 5 nurses and 5 support staff working

Answer:

1. 128 pages.

2. (y - x) + 1

3. 6 pages.

4. Helps to formulate the expression for the number of pages read.

Step-by-step explanation:

1. George will read pages 385 through 512 in his karate history book. And we are asked to find the number of pages that he will read.

The required number of pages that George read will be = (512 - 385) + 1 = 128 pages.

2. If he read from page number x through page number y then the general rule of finding the number pages that he read will be = (y - x) + 1

3. If x = 500 and y = 505, then the number of pages read is = (505 - 500) + 1 = 6 pages.

Again, if x = 5 and y = 29, then again the number of pages read is = (29 - 5) + 1 = 25 pages.

4. The rule just formulates the expression for the number of pages read and it eases the calculation for the number of pages read. (Answer)

(m-2)÷5= (m-4)÷3 !!!10 POINTS!!! (I know it's now much but I need help)

koban [17]

Answer:

m=7

m−2

m−4

(m−2)*(3)=(m−4)*(5)

3m−6=5m−20

Step 2: Subtract 5m from both sides.

3m−6−5m=5m−20−5m

−2m−6=−20

Step 3: Add 6 to both sides.

−2m−6+6=−20+6

−2m=−14

Step 4: Divide both sides by -2.

−2m

−2

−14
