Answer:

If both computers are working together, it will take 24 minutes to do the job

Step-by-step explanation:

It is given that,

There are two computers.The slower computer can send all the company's email in 60 minutes.

The faster computer can complete the same job in 40 minutes

<u>To find the LCM of 40 and 60</u>

LCM (40, 60) = 120

<u>To find efficiency of 2 computers</u>

Let x be the efficiency of faster computer and y be the efficiency of faster computer

x = 120/40 = 3

y = 120/60 = 2

then, x + y = 3 + 2 = 5

Therefore efficiency of both the computer work together = x + y =5

<u>To find the time taken to work both the computer together</u>

time = 120/5 = 24 minutes

Soft drinks are sold in aluminum cans that measure 6 inches in height and 2 inches in diameter. How many cubic inches of drink a
pychu [463]

Answer:

113.04 cubic inches.

Step-by-step explanation:

We have been given that soft drinks are sold in aluminum cans that measure 6 inches in height and 2 inches in diameter.

To find the amount of drink contained in 6 cans, we will find the volume of 1 can using volume of cylinder formula.

\text{Volume of cylinder}=\pi r^2h, where,

r = Radius of cylinder,

h = Height of cylinder.

First of let us divide diameter of given cylinder by 2 to get the radius of our cylinder as diameter is 2 times the radius.

\text{Radius}=\frac{2\text{ inches}}{2}

\text{Radius}=1\text{ inch}

Upon substituting our given values in volume formula we will get,

\text{Volume of can}=\pi*\text{(1 inch)}^2*\text{6 inch}  

\text{Volume of can}=3.14*\text{(1 inch)}^2*\text{6 inch}

\text{Volume of can}=18.84\text{ inch}^3

Therefore, one can of soft drink contains 18.84 cubic inches of drink.

To find the amount of drink contained in 6 cans we will multiply volume of 1 can by 6.

\text{Volume of 6 cans}=6\times 18.84\text{ inch}^3

\text{Volume of 6 cans}=113.04\text{ inch}^3  

Therefore, 6 cans of soft drink contain 113.04 cubic inches of drink.

A book club has 200 members
nikklg [1K]
So these are decmials of the accutal total so

.32=32%
what makes this question easy is that there are 200 members so to convert the percents into accutall numbers so like .32=32%=64 people (since 200 is 2 times of 100)

A. fiction of 31-40 compared to 21-30
fiction 31-40=.38=38%=76 readers
fiction 21-30=.32=32%=64 readers
76-64=12
A is FALSE

B. so we want to know how many people are 31-40 and prefer fiction
so .38=38% and 38% of 200=76
B is FALSE

C 43 members are 21-30
so we look at the total row for the 21-30 people and see that .43 or 43% or 86 people are in the 21-30 age group
C is FALSE

D. 140 members prefer fiction
look at the total column for fiction and see that .70 like fiction .70=70%=140 people
D is TRUE

so A,B,C are FALSE
D is TRUE

Answer:

if your solving for N= 1/18x + -1/6y

if your solving for X x=18n+3y

Step-by-step explanation:

Let's solve for n.

x−3y=18n

Step 1: Flip the equation.

18n=x−3y

Step 2: Divide both sides by 18.

if your solving for y then its
