Answer:

1 hour

Step-by-step explanation:

No. of pages print in 1.5 hours = 900

dividing LHS and RHS by 1.5 so that we get 1 hour in LHS

no. of page print in 1.5/1.5 (1) hours = 900/1.5 = 600.

Thus, it takes 1 hour to print 600 pages.

Given that we have to find  how

long will it take her to print a book of 600 pages.

Answer is 1 hour.

If a student is 65.0 in tall, what is her height in m? (2.54 cm = 1 inch)
spayn [35]

Answer:

Height of the student=1.651m

Step-by-step explanation:

Given: Height of a student= 65.0 inch.

To find: Height of a student in meters.

Solution:

We know that 1 inch=2.54 cm, then

65.0 inch will be =2.54{\times}65.0

65.0 inch will be=165.2 cm

Also, we know that 1cm=\frac{1}{100} m, then

165.2 cm will be equal to=\frac{1}{100}{\times}165.1

165.2 cm will be equal to=1.651 meters

Therefore, the height of a student in meters will be 1.651 meters.

Complete the equation of the line whose slope is 5 and y intercept is (0,4)
irina1246 [14]

y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)

<em><u>Solution:</u></em>

Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c ---- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given that, slope = m = 5

y intercept is (0, 4)

So, c = 4

<em><u>Substitute c = 4 and m = 5 in eqn 1</u></em>

y = 5x + 4

Thus the equation of line is found
