A copy machine can print 480 copies every 4 minutes. A teacher printed 720 copies. How long did it take to print?

Answer:

Ans = 42

Step-by-step explanation:

just substitute the variables with their respective value

x² + 2y ÷ w + 3z

= 5² + 2(8) ÷ 2 + 3(3)

= 25 + 16 ÷ 2 + 9 <bear in mind, have to do multiplication/division before addition/substraction>

= 25 + 8 + 9

= 42

Answer:

Step-by-step explanation:

X + (X + 4) + (X - 7) = 54

3X - 3 = 54

3X - 3 + 3 = 54 + 3

3X = 57

3X / 3 = 57 / 3

X = 19

Y = (19 + 4) = 23

Z = (19 - 7) = 12

Sam's age = 19

Dana's age = 23

Alex's age = 12

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.

Answer:

C $1187

Step-by-step explanation:

diameter = 12ft

radius = 6 ft

area = πr²

= 3.14×6×6

= 113.04 ft²

paving stones is $10.5 per ft²

paving stones cost = 113.04×10.5 = 1186.92

; the nearest dollar do the paving stones cost is $1187

Step-by-step explanation:

Answer:

68%

Step-by-step explanation:

     Here, it asks for the percentage that attended, and percentage is a ratio expressed as a fraction of 100. First, we must start with the total number of students, not to be confused with the total number of students who attended. The total number of students in the class is 25, which we must multiply to get to a hundred.

     This depends on the number of course. For example, if the number were to be greater than 100, then you would divide, but never adding or subtracting, but in this case, we must stick with multiplying as 25 is less than 100. As you should know, 24 times 4 equals hundred, so you must multiply 17 by 4 too in order for it to be equal, which leaves you with 68/100 attending the part, meaning the percentage of students attending the dance is 68%.

Answer:

" all numbers less than -27 "

Step-by-step explanation:

The instructions for this problem most likely go like this:  "solve the following identity."  In other words, find an inequality for n.

Start by multiplying both sides of the given inequality by 3, to eliminate the fraction 1/3:

n < -27

The solution:  " all numbers less than -27 "

Answer:

395.85

Step-by-step explanation:

If the diameter is 12, then the radius must be 6. Following the formula of pi: 2 * pi * radius, our result is 37.7. 37.7 * 10.50 is 395.85

I really hope this helps. My memory of circles and pi isn't the best.

Answer:

Stem and Leaf Plot ⇒ Makes it easy to see the largest, smallest and most common data values.

Double Bar Graph ⇒ Compares two sets of data.

Bar Graph ⇒ Shows whether one type of data increases, decreases or neither when another type of data increases.

Scatter Plot ⇒ Shows the frequency of results and trends clearly.

Step-by-step explanation:

Stem and Leaf Plot makes a set of data easy to see and shows common data values together.

Double bar graph is the only graph that focuses solely on 2 sets of data.

Bar Graph description is a bit weird for this one to me but it's the last one (I did others first) and it is close enough.

Scatter plot is best at showing frequency and trends and to see the approximate increase/decrease of many data points.

Answer:

14. decrease

15. divide 59.95 by 40

16. increase

Answer:

462

Step-by-step explanation:

720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.

720*5/6= 600

The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.

600*0.77 = 462

The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.

Given :

The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:

Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.

Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:

[tex]=\dfrac{720}{120}\times 100[/tex]

= 600

Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.

Step 4 - So, the total cost of the laptop at which an employee purchase is:

[tex]=\dfrac{77}{100}\times 600[/tex]

= 462
