There are 4 queens in a standard deck of 52 CARDS. You pick one card at random. What is the probablity of not picking a queen?

Answers

Answer 1

Answer: Find the number of cards that are not queens by subtracting 4 from 52, which equals 48. So 48 cards out of 52 cards are not queens. This can be written as 48/52. Simplify this fraction. (48/4 / 52/4) = 12/13. The probability of not picking a queen is 12/13. Another, simpler, way to solve it is this: if you know there are 13 suites in a deck of cards, excluding one suite, in this case queens, will give you 12 out of 13 suites left that are not that suite.

Answer 2

Answer: 48/5224/2612/13So the probability of not choosing a queen is 12/13

the length of a rectangle is 2 cm more than the width. if the area of the rectangle is 24 cm2 what is the length of the rectangle?

Answers

Answer: The length is 6 and thw wodth is 4

Step-by-step explanation:

If you find two numbers that multiply to 24, you have three sets of numbers, but 6 and 4 are the only numbers that are two centimeters apart

Final answer:

The question is about finding the length of a rectangle. By creating and solving a quadratic equation with provided information, the width and length of the rectangle are 4 cm and 6 cm respectively.

Explanation:

The problem involves finding the length of a rectangle. To solve this, we need to consider the fact that we know information about the dimensions and area of the rectangle. The area of a rectangle is obtained by performing the multiplication of the length and the width. In this specific problem, it's stated that the length is 2 cm more than the width, and we also know that the area of the rectangle is 24 cm2.

Let's represent the width by x. Therefore, the length would be x+2. Since the area is the length multiplied by the width, we create the equation x*(x+2) = 24, which simplifies to x2+2x=24. Subtracting 24 from both sides, we get x2+2x-24 = 0.

This a quadratic equation and we'll solve for x using the quadratic formula, which results in x = 4 or x = -6. Since the width cannot be negative, x = 4 cm. After this, substitute the width (x) into the length equation. The length (x + 2) is 4 cm + 2 cm = 6 cm.

What mixed number represents 2.85

Answers

First, take out the whole number portion, and solve the decimal part, which is 0.85. 0.85 = 85/100. So, the mixed number would be 2 85/100. However, most teachers want you to simplify your mixed numbers, so divide both numbers by a factor that you think is common. 5 is a common factor, so 85/5 = 17. 100/5 = 20. So, the answer is simplified to 2 17/20.
Hope that helped.
