erika has 3 pieces of ribbon. each piece is 25 yards long she needs to cut pieces that are 22 inches long . what is the greatest number of 22-inch pieces that she can cut from the three ribbons ?

Answers

Answer: 120 pieces.

Step-by-step explanation:

We know that 1 yard = 36 inches

Given: The length of each piece of ribbon= 25 yards $=25*36=900\text{ inches}$

If she needs to cut 22 inches long pieces, then the total number of pieces cut from 1 ribbon $=(900)/(22)=40.0909\approx40\text{ pieces}$

Thus, the total number of pieces she cut from 3 ribbons $=3*40=120\text{ pieces}$

Hence, the greatest number of 22-inch pieces that she can cut from the three ribbons =120

Well 1 yard is 36 inches so 25 yards is 900 and then divide the 900 by 22 which equals 40.9090 but you have to put this down to 40 and because you have 3 ribbons it's 40 x 3 = 120!

What is the value of C?

C+12( 12+5)=149

Answers

So first add up (12+5)
=17 now add the 12
=29
Now take away 29 from 149 and that gives you 120

HI,
SO first in P.E.M.D.A.S

So 12+5 =17

12+17 = 29

so what plus what = 149

120 is you answer

How do you solve for L?

L=5B
L+7=3(B+7)

Answers

remember
a(b+c)=ab+ac
and you can do ANYTTHING to be
L=5B
divide both sides by 5
L/5=B
sub L/5 for B in other equation
L+7=3((L/5)+7)
distribute
L+7=(3L)/5+21
minus 7 both sides
L=(3L)/5+14
time boths sides by 5
5L=3L+70
minus 3L both sides
2L=70
divide 2
L=35

You first plug in 5B for L in the 2nd equation and you get 5B+7=3B+21 (distributive property). Then you simplify and you get B = 7. Then you plug 7 back in the first equation and get L = 35.

Candace used 5/8 of her savings to buy a $531.25 laptop. How much did she have in savings before purchasing the laptop?

Answers

$x-savings\n\n(5)/(8)x=531,25\ \ \ \ |\cdot(8)/(5)\nx=850\n\nCandance\ had\ \$ 850\ savings.$

Final answer:

To find out how much Candace had in savings before purchasing the laptop, we will use the equation: Savings before purchase = Total savings + Amount spent on laptop. Candace had $849.20 in savings before purchasing the laptop.

Explanation:

To find out how much Candace had in savings before purchasing the laptop, we will use the equation:

Savings before purchase = Total savings + Amount spent on laptop

Since Candace used 5/8 of her savings to buy the laptop, the amount spent on the laptop is 5/8 of the total savings. We can set up the equation as:

Total savings = Amount spent on laptop / 5/8
Total savings = $531.25 / 5/8
Total savings = $531.25 * 8/5
Total savings = $849.20

Therefore, Candace had $849.20 in savings before purchasing the laptop.

Stefanie is painting her bedroom. She can paint 12 and 2/3 square feet in 2/5 of an hour. How many square feet can she paint in one hour?

Answers

The number of square feet that she can paint in one hour will be 31.67 square feet per hour.

What is the rate?

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Stefanie is painting her bedroom. She can paint 12 and 2/3 square feet in 2/5 of an hour.

The total number of squares is given as,

Area = 12 + 2/3

Area = 38/3 square feet

Then the number of square feet that she can paint in one hour is given as,

Rate = (38/3) / (2/5)

Rate = (38 x 5) / (2 x 3)

Rate = 31.67 square feet per hour

The number of square feet that she can paint in one hour will be 31.67 square feet per hour.
