At union station, you notice that three subway lines just arrived at the same time. How long must you wait until all three lines

Dmitry_Shevchenko [17]

Answer:

You must wait 60 minutes for all three lines to arrive at Union Station at the same time again.

Step-by-step explanation:

The complete question in the attached figure

Step 1

Find the least common multiple (LCM) of the three numbers

List the prime factors of each number

$10=(2)(5)\\12=(2^2)(3)\\15=(3)(5)$

Multiply each factor the greatest number of times it occurs in any of the numbers to find out the LCM

The LCM is equal to

$(2^2)(3)(5)=60$

therefore

You must wait 60 minutes for all three lines to arrive at Union Station at the same time again.

"mailing labels are sold in packages of 16 envelopes are sold in packages of 20 what is the least number of labels and envelopes

myrzilka [38]

Answer:

80 labels

Step-by-step explanation:

The number of packages are 16 envelopes and 20 envelopes

We solve using LCM Method

We find the Multiples of 16 and 20

Multiples of 16:

16, 32, 48, 64, 80, 96, 112

Multiples of 20:

20, 40, 60, 80, 100, 120

Therefore,

LCM(16, 20) = 80

The least number of labels and envelopes you can buy so that there is one label on each envelope with none left over = 80 labels

DUS is a 30°-60°-90° triangle with short leg SU. If SU = x, determine the

vitfil [10]

Answer:

SD = 2x

UD = x $\sqrt{3}$

Step-by-step explanation:

The hypotenuse of a 30-60-90 triangle is 2 times the length of the shorter leg.

SU is the shorter leg = x

So, SD = 2x

The longer leg of a 30-60-90 triangle is $\sqrt{3}$ times the shorter leg.

So, UD = x $\sqrt{3}$
