Answer:

Step-by-step explanation:

formula for triangle is base x height divided by 1/2

alexandr1967 [171]

Answer:

separate and square both the top and bottom

the square of square root three is just 3 and the square of  3 (the bottom of the fraction) is 9

so now you have 3(i^2) /9

you can simplify this by three  and then i^2 is -1

you now have -1/3 and thats the final answer

Draw 2 cards from a standard deck of 52 cards. What is the probability that the first card is a queen and the second card is a k
bixtya [17]

Answer:

4/663

Step-by-step explanation:

There are four queens.  The probability that the first card is a queen is 4/52.

There are four kings.  There are 51 cards left after the first card has been drawn, so the probability that the second card is a king is 4/51.

Therefore, the probability that the first card is a queen AND the second card is a king is:

P = 4/52 × 4/51

P = 4/663

Need help plsss give you brainliest plssss help me it’s rounding money cents, dime and dollar
Vladimir [108]

Answer:

Please see the attached image for solution.

Step-by-step explanation:

Cent:  Rounding to the nearest cent or multiple of 0.01.

Dime: Rounding to the nearest 10 cents or multiple of 0.10.

Dollar: Rounding to the nearest dollar or multiples of 1.

For example, in question #21:

To round $12.3456 to the nearest cent:  you must look at the hundredths place, and pay attention to the digit to its right. In this case, the digit at the hundredths place is 4, and to its right is 5. Therefore, you must round it up to 5, making it $12.3<u>5</u>.

To round $12.3456 to the nearest dime:  you must look at the tenths place, and pay attention to the digit to its right. In this case, the digit at the tenths place is 3, and to its right is 4. Since 4 is less than 5, you must round 4 down to 0, making it into $12.<u>3</u>0.

To round $12.3456 to the nearest dollar:  you must look at the ones place, and pay attention to the digit to its right. In this case, the digit at the ones place is 2, and to its right is 3. Since 3 is less than 5, you must round 3 down to 0, making it into $1<u>2</u>.00.
