They must sell, 30 cups of lemonade. How I got my answer.

Since it cost $1.20 to start, and a cup of lemonade cost $0.6 to make and there selling them at $0.10 each. So we know they are making a $0.4 profit off of each cup of lemonade. We now have to multiply 4×30=120.

I hope this helps!

Answer:

<h2>They need to sell at least 13 cups to gain profits.</h2>

Step-by-step explanation:

Givens

  • The initial cost is $1.20.
  • Each cup of lemonade costs 6 cents to make.
  • May's children sell 10 cents a cup.

First, we need to represents the cost of their investment.

0.06x=1.20, because each cup costs 6 cents, and the initial costs of all is $1.20.

That means,

x=\frac{1.20}{0.06}= 20

They can produced 20 cups.

However, they already sell a cup for 10 cents. So, how many cups they need to sell to gain profits? We need to establish a similar relation,

0.10x=1.20\\x=\frac{1.20}{0.10} = 12  

This means if they sell 12 cups, they will just cover the investement, that is, zero profits.

Therefore, they need to sell at least 13 cups to gain profits.

Answer:

\pi radian

Step-by-step explanation:

We know that angle for a full circle is 2\pi

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of  angle for a full circle = 1/2 * 2\pi = \pi

Thus, answer is \pi radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as \pi radian.
