Which is the least common multiple of 4 and 12

Mathematics

The answer is 12. My explanations is that LCM is the smallest number that both numbers can fit into. 12 fits into 12 once, and 4 fits into 12 3 times, so 12 is the answer.

Does anyone know the answer to this scale and unit conversion GED math problem? Thank you very much!
aliya0001 [1]

Answer:

Flour 5\dfrac{1}{2}\ c

Sugar 2\dfrac{2}{3}\ c

Butter 1\dfrac{1}{2}\ c

Eggs 2

Baking powder 7\ t

Vanilla extract 3\ t

Step-by-step explanation:

There will be 16 people at the party. Each person will eat 3 cookies, so all people will eat 16\cdot 3=48 cookies.

Given cookie recipe makes 24 cookies, so to make 48 cookies you need

48:24=2 portions.

Thus,

              1 portion                      2 portions

Flour      2 \dfrac{3}{4}\ c               2\dfrac{3}{4}\cdot 2=2\cdot 2+\dfrac{3}{4}\cdot 2=4+\dfrac{3}{2}=4+1 \dfrac{1}{2}=5\dfrac{1}{2}\ c

Sugar    1\dfrac{1}{3}\ c                  1\dfrac{1}{3}\cdot 2=1\cdot 2+\dfrac{1}{3}\cdot 2=2+\dfrac{2}{3}=2\dfrac{2}{3}\ c

Butter    \dfrac{3}{4}\ c                  \dfrac{3}{4}\cdot 2=\dfrac{3}{2}=1\dfrac{1}{2}\ c

Eggs      1                           1\cdot 2=2

Powder 3\dfrac{1}{2}\ t                  3\dfrac{1}{2}\cdot 2=3\cdot 2+\dfrac{1}{2}\cdot 2=6+1=7\ t

Vanilla   1\dfrac{1}{2}\ t                  1\dfrac{1}{2}\cdot 2=1\cdot 2+\dfrac{1}{2}\cdot 2=2+1=3\ t

Dash offers and unlimited talk and texting plan for $80 per month AB&C charges $0.20 per text message and $55 for 1,000 min
mr_godi [17]

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y
