If it takes a secretary 20 which type 400 pages how many pages can he
type in 45 minutes

I think its 20 minutes

am i right?

Step-by-step explanation:

I am not sure about my ans

but..

it can 800 or more pages

hope it helps you...

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.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
