Answer:

900pages=45minutes

Step-by-step explanation:

Step 1: Find the unit rate=how many pages he can type in 1 minute

to find the unit rate,

k=y/x

y=400 pages

x=20 min

400/20=20 pages in 1 minute

Step 2: Multiply the amount of pages by 45

k times x = y

20 times 45= 900 pages in 45 minutes

So, it will take the secretary 45 minutes to type 900 pages.

A.) write an equation in slope intercept form for the total cost of any number of tickets at 7 tickets for $5.
MrMuchimi
Slope intercept form is y = mx + b

7 tickets for $5 means that 1 ticket costs 5/7 dollars

So for part a, the slope intercept form would be:

y = \frac{5}{7}x

where x is the number of tickets, and y is the price.

For part b)

The slope intercept form is:
y = 25x

where x is the number of all you can ride wristbands you buy, and y is the total price.

C) Bhurashi can do 1/3 part of a work in 6 days.
Simora [160]

Answer:

<h2>i. 18 days</h2><h2>ii.\frac{1}{18} part of work</h2><h2>iii. \frac{1}{2} part of work</h2><h2 />

Step-by-step explanation:

i.

\frac{1}{3} part of work can be done in 6 days.

Days taken to complete the whole work:

= 6 * 3

= 18 days

ii. Whole work will be done in 18 days.

So, 1 day work = \frac{1}{18}

iii. Work done in 9 days :

\frac{1}{18}  \times 9

=  \frac{1}{2}

So, remaining work :

1 -  \frac{1}{2}

=  \frac{1 \times 2 - 1}{2}

=  \frac{2 - 1}{2}

=  \frac{1}{2} part of work

Hope this helps...

Good luck on your assignment..
