Which is more 0.02 or 0.1 ?

Answers

0.1 is the same as 0.10. If you forget the decimal it is 02 and 10 which is the same as 2 and 10. 10 is bigger than 2 so the answer is 0.1

.1 because if you change .1 to = .02 it is .10 and .10 is bigger than .2

Each adult paid 75 cents and each student paid 50 cents at the schoot play. A total of 750 attended. How many adults attended if the receipts totaled $437.50?

Answers

Answer:

250 adults

Step-by-step explanation:

With the information of the problem we have a system of two linear equations:

$x+y=750$

$0.75x+0.50y=437.50$

Where x represent the quantity of adults and y represent the student. Solving the first equation for x we have:

$x+y=750\nx=750-y$

Using this result in the second equation:

$0.75x+0.50y=437.50\n0.75(750-y)+0.50y=437.50\n562.5-0.75y+0.50y=437.50\n-0.25y=437.50-562.5\n-0.25y=-125\n0.25y=125\ny=(125)/(0.25)\ny=500$

With this result we know that we have 500 students, using the result of y in the first equation we will find the answer for x then:

$x+y=750\nx+500=750\nx=750-500\nx=250$

Then the we have 250 adults.

What is the LCM of 13 and 26

Answers

The lest common multiple is 26. If you do multiples of each number

13:13,26
26: 26

Both of their lest common multiples would be 26

$LCM\ is\ the\ least\ common\ number\ that\ is\ multiply\ of\ both:\n\n Factors\ of\ 13\n 13:13\n\n Factors\ of\ 26:\n 26:2\n 13:13\n\n LCM(13,26)=2*13=26\n\n \textbf{LCM(13,26)=26}$
