What is the maximum number of cups of coffee that can be served?
The water tank of a coffee maker is shown below. She infuses 350 ml cups.

9 cups

Step-by-step explanation:

1 m³ = 10⁶ ml

0.21×0.05×0.3 = 0.00315 m³ × 10⁶

= 3150 ml

No. of cups: 3150 ÷ 350 = 9

9 cups

Step-by-step explanation:

The volume is V=w×L×h, where L=0.21m, w=0.05m and h=0.3m

V=0.21×0.05×0.3=63×5×10^(-5)m³

V=315×10^(-5)m³=3.15dm³=3.15liters

This is because 1dm³=1l (by definition)

The volume of a cup: u=350ml

Number of caps n=V/u=3.15l/350ml

n=3150/350=9cups

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
