Answer:
Step-by-step explanation:
The probability of drawing a red card is 1/2, since half of the cards in a deck are red. The probability of drawing an ace from a deck is 1/13, since there is an equal chance to pick any of the 13 numbers.
P(red card and ace)= P(red card)*P(ace)=1/2 * 1/13=1/26
Answer:
Area of the Net is incorrect
Step-by-step explanation:
Base Surface Area = π×12^2
= 452.38934211693 inches^2
Lateral Surface Area = π×12×√12^2 + 15^2
= 724.1762903163 inches^2
Total Surface Area = 1176.5656324332 inches^2
Answer: x=-7
Step-by-step explanation: hope this help :)
Type 1 rice :
7-ounce package costs = 2.59.
Cost of 1-ounce of Type 1 rice= 2.59/7 = $0.37
Type 2 rice :
12-ounce package costs = $4.56
Cost of 1-ounce Type 2 rice = 4.56/12 = $0.38
Type 3 rice :
18-ounce package costs = $ 6.30
Cost of 1-ounce Type 3 rice = 6.30/18 = $0.35.
From the above calculations, we can see that the cost of 1-ounce Type 3 rice is lowest. Therefore, 18-ounce package is Best Buy.
The <em><u>correct answers</u></em> are:
90°, 180° and 270°
Explanation:
Squares have rotational symmetry at 90°. This can be found by dividing the number of degrees in a circle, 360, by the number of sides, 4:
360/4 = 90
This means that at all multiples of 90, the square will rotate onto itself. This means that 90, 180 and 270 are all correct.
