Answer:
56 dollars are earned for recycling 28 pounds of copper.
Step-by-step explanation:
Quantity of copper recycled = [tex]p[/tex] pounds
Amount earned in dollars for recycling [tex]p[/tex] pounds of copper = [tex]2p[/tex]
Also,
Quantity of copper recycled = [tex]28[/tex] pounds
Therefore,
Amount earned in dollars for recycling [tex]28[/tex] pounds of copper = [tex]2(28)=56[/tex] dollars
So,
56 dollars are earned for recycling 28 pounds of copper.

Ben's living room is a rectangular measuring 12 yards x 204" by how many feet does the length of the room exceed the with the length of the room exceeds the width by blank feet
Answer:
The length of the room exceeds the width by 19 feet
Step-by-step explanation:
From the question, the room measures 12 yards x 204", that 12 yards x 204 inches. To determine by how many feet the length of the room exceeds the width, we will first convert both units of measurement ( yards and inches) to feet.
To convert 12 yards to feet,
1 yard = 3 feet
∴ 12 yards will be 3 × 12 feet = 36 feet
To convert 204" to feet
12" = 1 foot
∴ 204" will be 204/12 feet = 17 feet
Hence, the room measures 36 feet × 17 feet
That is, Length of the room = 36 feet
and width of the room = 17 feet
Now, to determine by how many feet the length of the room exceeds the width, we will deduct the width of the room from the length of the room, that is,
36 feet - 17 feet = 19 feet
Hence, the length of the room exceeds the width by 19 feet.

Can a chord be a diameter?
Answer:
yes
Step-by-step explanation:
ΔABC ~ ΔEFD
Step-by-step explanation:
A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.Hope this is fine for youPlz help me with both question and on the last question plz show ur work I will give brainliest

Answer:
The answer is below
Step-by-step explanation:
We are asked to create a box plot. To create a box plot, we need to determine the minimum point, maximum point, lower quartile, upper quartile, interquartile range, median.
First we have to arrange the data in ascending order. This gives:
85, 150, 180, 200, 210, 250, 450
The minimum point = 85
The maximum = 450
[tex]Median=\frac{2}{4}(n+1)^{th}term=\frac{2}{4}(7+1)=4^{th}\ term=200\\\\Median=200 \\\\Lower\ quartile(Q_1)=\frac{1}{4}(n+1)^{th}term=\frac{1}{4}(7+1)=2^{nd}\ term=150\\\\Lower\ quartile(Q_1)=200 \\\\Upper\ quartile(Q_3)=\frac{3}{4}(n+1)^{th}term=\frac{3}{4}(7+1)=6^{th}\ term=250\\\\Upper\ quartile(Q_3)=250 \\\\Interquartile\ range=Q_3-Q_1=250-150=100[/tex]

Janie ordered boxed lunches for a student advisory committee meeting. Each lunch costs $4. The total cost of the lunches is $47, including a $7 delivery fee. Write and solve an equation to find x, the number of boxed lunches Janie ordered.
Answer:
10 lunches
Step-by-step explanation:
$47-$7=$40
40/4=10
Hello, 928747!
So we are trying to find how many boxed lunches Janie ordered.
Each box is $4.00 and the total cost is $47.00 + delivery fee of $7.00
So to find this, we will first subtract the delivery fee because that does not count towards the lunches.
47 - 7 = 40
So the boxed lunches cost $40.00
To find how many Janie ordered, we will divide 4 by 40
40 ÷ 4 = 10
So Janie bought 10 boxed lunches.
The equation would be (47 - 7) ÷ 4

1. In 1980, approximately 6 million women enrolled in college in the United States. The number of women who enroll in college has increased at a rate of 0.14 million women per year. There were about 5.4 million men enrolled in college in 1980, and that number has increased at a rate of 0.08 million men per year. In what year (prior to 1980) were an equal number of men and women enrolled in college?
Answer:
Step-by-step explanation:
First, you can plot this using a table. One side can be 'Women' and the other 'Men'. One the vertical side of it, write '1980', '1981', '1982', etc., for maybe fifteen years to be on the safe side. Then, your starting value is 6 million and 5.4 million, respectively.
Finally, start adding up, It will be, 6.14 million, 6.28 million, etc., and 5.4 million, 5.48 million, etc.
Once you're done, you can circle the year both were the same, and you can even plot this on a graph

Malik and Tasha each worked three days in one week at the grocery store. Each day, Malik worked 2 fewer hours than Tasha. They worked a total of 18 hours that week. Find the number of hours that Tasha worked each day.
Answer:
Step-by-step explanation:
Firstly, since they worked 18 hours over 3 days, they worked a total of 6 hours each day. Since Malik worked 2 fewer hours than Tasha, we have that Tasha worked (6+2)/2 = 4 hours each day and Malik worked 2 hours each day.

how would you solve 17=w/4?
Answer:
Solution for 17=w-4 equation:
17=w-4
We simplify the equation to the form, which is simple to understand
17=w-4
We move all terms containing w to the left and all other terms to the right.
-1w=-4-17
We simplify the left and right sides of the equation.
-1w=-21
We divide both sides of the equation by -01 to get w.
w=21

sarita's father's age is 49 years his age is 4 years more than three times Sarita age find the present age of Sarita
Answer:
15years
Step-by-step explanation:
Let the present age of sarita be x
Sarita father age = 49years
If his father age is 4 years more than three times Sarita age, this is expressed as;
49 = 3x + 4
Sind x
3x = 49-4
3x = 45
x = 45/3
x = 15
hence present age of sarita is 15years
