A printer can print 27 pages in 4.5 min. How much time does it need to print 324 pages?
lutik1710 [3]

Answer:

54 minutes

Step-by-step explanation:

We can write a proportion to solve this problem.  Put the number of pages over the minutes

27 pages           324 pages

--------------    = ---------------

4.5 minutes         x minutes

Using cross products

27 * x = 324 * 4.5

27x = 1458

Divide each side by 27

27x/27 = 1458/27

x =54

These data show the number of miles each of the 9 members of a track team ran for the week. 11 11.5 10.5 17 14.5 14.5 18 17 19 W
Vitek1552 [10]
Given:
<span>11 11.5 10.5 17 14.5 14.5 18 17 19

Arrange in chronological order from least to greatest.
10.5 ; 11 ; 11.5 ; 14.5 ; 14.5 ; 17 ; 17 ; 18 ; 19

</span><span>I used an online lower and upper fence calculator to get the necessary data.

Minimum: 10.5
Maximum: 19
Q1: 11.25
Q2 or median: 14.5
Q3: 17.5

Interquartile range can be solved by subtracting the value of Q1 from the value of Q3

IQR = Q3 - Q1
IQR = 17.5 - 11.25
IQR =  6.25  CHOICE A. </span>

Jim is half his mother's age. His mother is 5 years younger than his father, in total their ages are 100 years. What is Jim's ag
atroni [7]

Jim is 19

let fathers age be x then mothers age = x - 5 and Jim's age is \frac{1}{2}(x - 5)

Total their ages and equate to 100

x + x - 5 + \frac{1}{2}(x - 5 ) = 100

multiply through by 2 to eliminate the fraction

2x + 2x - 10 + x - 5 = 200

5x - 15 = 200 ( add 15 to both sides )

5x = 215 ( divide both sides by 5 )

x = 43

father is 43 years, mother is 38 and Jim is 19

The equation represents a hyperbola centered at the origin with a directrix of . what is the value of b? 10 16 20 26
Rom4ik [11]

the value of b is = 10.

The equation of a hyperbola is x^2/24^2 - y^2/ (10)^2= 1.

<h3>What is hyperbola?</h3>

The geometric characteristics of a hyperbola or the equations for which it is the solution set characterize it as a particular kind of smooth curve that lies in a plane. Mirror reflections of each other that resemble two infinite bows make up a hyperbola's two connected components or branches.

<h3>What is the general formula for hyperbola?</h3>

The general formula for hyperbola = (x - h)²/a²- (y - k)²/(b)² = 1

<h3>According to the given information:</h3>

x²/24 - y²/(b)² = 1

(x - 0)²/24 - (y -0)²/(b)² = 1

a=24,h=0 and k=0

Now equation of the directrix

x=a²/c...(1)

and we know x=576/26...(2)

Therefore from 1 and 2 we get

24²/c=576/26.

isolate the c so we get,

C=26

C= center of focii

c = √(a² + b³)

c² = a² + b²

b = c² - a²

b = 10

So we get the value of b is 10.

Therefore the equation of a hyperbola is x²/24² - y²/ (10)² =  1.
