Answer:

7 cups of butter

Step-by-step explanation:

2 cups of butter for each three cups of flour

Let the number of butter cups for 10 cups of flour = x

2 cups of butter = 3 cups of flour flour

x = 10 cups of flour

Cross multiply :

3x = 10 * 2

3x = 20

x = 20 / 3

x = 6.666

x = 7 cups of butter (nearest whole number)

Answer:

The total surface area of the given cone is

$S = 4( \sqrt{3}+1)\pi cm^2$

Step-by-step explanation:

Step 1:-

Formula:-

The total surface area of cone is

$S.A = \pi r l +B$

$S.A = \pi r l +area of base$

$S.A = \pi r l+ \pi r^2$ ........(1)

Step 2:-

Given slant height $l = 2\sqrt{3} cm$

and radius of the circle (base) = 2

substituting these values in equation (1)

$S.A = \pi (2)(2\sqrt{3} ) + \pi (4)$

on simplification, we get

$S.A = \pi (4\sqrt{3}+4)$

Final answer :-

$S.A = 4 (\sqrt{3}+1)\pi cm^2$

Few Questions! NEED HELP PLEASE , CONFUSED!!

Firdavs [7]

Multiples of 11 between 1 and 30:

11, 22

So there are 2 numbers that are multiples of 11 in the bin. There are a total of 30 cards, so the probability is written as 2/30. Or we can simplify it to 1/15.

For the next question:

There are a total of 3 + 8 = 11 balls in the bag.

The probability of choosing a red ball is 3/11.

The probability of choosing a green ball is 8/11.

Multiply the three fractions:

3/11 * 3/11 * 8/11 = 72/1331

So the probability is 72/1331.

For the last question:

A standard deck of cards has 52 cards.

There are 4 queens and 4 kings in the deck.

Probability of choosing a queen is 4/52, and the probability of choosing a king AFTER you already chose a queen is 4/51.

Multiply the two fractions:

4/52 * 4/51 = 16/2652

So the probability is 16/2652 or 4/663
