Leah has 6 1/4​ yards of ribbon to make bows. Each bow is made from a piece of ribbon that is 1/3 ​ yard long. What is the maximum number of complete bows Leah can make?

Answers

Leah can make 18 complete bows. She will then have 1/4 yards of fabric left over. This is true because there are 3 thirds to a whole and there are 6 complete yards of ribbon. 3 x 6 = 18. Then we get left with an extra 1/4 yards of fabric because 1/4 is less and a third.

What is the average per day?

Answers

To get the average in this case, divide 30 by 5:

30 hrs ÷ 5 days = 6 hrs/day
To get averages you have to divide the total number of units by the period of time/how many things there are. So in this case you divide 30 by 5 and get 6

Two welders working together can complete a job in 6 h. One of the welders, working alone, can complete the task in 15 h. How long would it take the second welder, working alone, to complete the task?

Answers

ur asking a bunch of these kind of rate problems xD
6 ( (1)/(15) + (1)/(x) )=1
In 6 hrs, the welder who does 1/15 of the job in 1 hr and the welder who does 1/x in 1 hr, complete the job (6 hrs.)
(1)/(15) + (1)/(x) = (1)/(6)
Multiply 30 on both sides to cancel out the fractions and we get:
2 + (30)/(x) =5
Solving for x:
30/x=3
3x=30
x=10
The second welder would take 10 hours.

HeLpPLZZZ (Edge). Which line on the graph represents the information in the table? Cost of Pencils Number of Pencils Total Cost (in $) 2 0.50 4 1.00 6 1.50 8 2.00 On a coordinate plane, the x-axis is labeled Number of pencils and the y-axis is labeled total cost in dollars. Line a goes through points (1, 4) and (2, 8). Line b goes through points (1, 2) and (2, 4). Line c goes through (2, 1) and (4, 2). Line d goes through (4, 1) and (8, 2). line a line b line c line d

Answers

Answer:

Line D- (4, 1) and (8, 2).

Step-by-step explanation:

The table representing the information is given below:

\left|\begin{array}{c|c}$Number of Pencils(x)&$Total Cost(in $)(y)\n----&----\n2&0.50\n4&1.00\n6&1.50\n8&2.00\end{array}\right|

On the coordinate plane, the x-axis is labeled Number of pencils and the y-axis is labeled total cost in dollars.

Therefore, any point that matches with the (x,y) pair on the table represents the information in the table.

Answers

x^2 -25
All I did was divide both and I got the answer.

Answer:  x^2 - 25


Explanation:

Here is a tip/ shortcut to multiplying binomials in the (a + b)(a - b) format.

The only things you have to look for is the factor of a * a and the factor of       b * b.

The reason being, a * -b and b * a cancel each other out no matter what.

For example

1. (x + 5)(x - 5)         Multiply x_(1) by x_(2)

  x * x = x^(2)

2. (x + 5)(x - 5)         Multiply x_(1) by -5 in the second binomial

  x * -5 = -5x

3. (x + 5)(x - 5)        Multiply 5 in the first binomial to x_(2)

  5 * x = 5x

4. (x + 5)(x - 5)        Multiply 5 in the first binomial to -5 in the second binomial

  5 * -5 = -25

5. Now that you have all of your answers, write your equation, in order, to look like this.

x^(2) - 5x + 5x - 25

6. -5x and 5x cancel each other out when combining like terms so you're left with.

x^(2) - 25


In the end, steps 2, 3, 5, and 6. can be taken out by doing this.

Just multiply x_(1) by x_(2) to get x^(2)

Then just multiply 5 in the first binomial to -5 in the second binomial to get -25

Then write your answer.

x^(2) - 25


This works because there is no need for steps 2,3,5, and 6 since they lead to the same outcome from doing steps 1 and 4.
