Step-by-step explanation:
If you are dealt two cards successively (with replacement of the first) from a standard 52-card deck, find the probability of getting a face card on the first card and an ace on the second. ( Round to 4 decimals )
The probability of getting a face card on the first card is 12/52, and the probability of getting an ace on the second card is 4/52.
Since the two events are independent (because we replace the first card), we can multiply the probabilities to find the probability of both events happening together:
P(getting face card on first card and ace on second card) = P(face card on first card) × P(ace on second card)= (12/52) × (4/52) = 48/2704 = 0.0177.
When you are dealt two cards from a standard deck of 52 cards, there are a certain number of possibilities for each card. For example, if you are trying to find the probability of drawing an ace, there are four aces in the deck, so the probability of drawing an ace on the first card is 4/52, or 1/13. However, if you are trying to find the probability of drawing an ace on the second card after drawing a face card on the first card, the probability is different. In this case, you know that the first card is a face card, which means that there are 12 cards in the deck that could be drawn. Since there are 52 cards in the deck, the probability of drawing a face card on the first card is 12/52, or 3/13. After you replace the first card, there are 52 cards in the deck again, but now there are only four aces because you know that the first card was not an ace. Therefore, the probability of drawing an ace on the second card is 4/52, or 1/13. Since the two events are independent (because you replace the first card), you can multiply the probabilities to find the probability of both events happening together. In this case, the probability is:
P(getting face card on first card and ace on second card) = P(face card on first card) × P(ace on second card)= (12/52) × (4/52) = 48/2704 = 0.0177
In conclusion, the probability of getting a face card on the first card and an ace on the second card is approximately 0.0177, or 1.77%. This means that out of every 100 times you draw two cards from a standard deck of 52 cards, you can expect to get a face card on the first card and an ace on the second card less than two times.

Pls help. It’s geometry
Susan had four bags of candy, each weighing 6 ounces. Isabel had one bag of candy weighing 1 pounds. Which girl has the more candy in weight? Your work will justify your answer.
Susan has more candy in weight compared to Isabel.
To compare the candy weights between Susan and Isabel, we need to ensure that both weights are in the same unit of measurement. Let's convert Isabel's candy weight to ounces for a fair comparison.
Given:
Susan: 4 bags x 6 ounces/bag = 24 ounces
Isabel: 1 bag x 16 ounces/pound = 16 ounces
Now that both weights are in ounces, we can see that Susan has 24 ounces of candy, while Isabel has 16 ounces of candy. As a result, Susan is heavier on the candy scale than Isabel.

What is the number of sides in a regular polygon when the measure of each interior angle is 162?
Answer:
20
Step-by-step explanation:
interior angle + exterior angle = 180°
162° + exterior angle = 180° ( subtract 162° from both sides )
exterior angle = 18°
the sum of the exterior angles of a polygon = 360° , then
number of sides = 360° ÷ 18° = 20

What is the formula for the sum of exterior angles in a polygon?
The sum of a regular polygon's exterior angles will always equal 360 degrees.
What is exterior angles?Exterior angles are those that are parallel to a polygon's inner angles but are on the outside of it. The sum of two internal opposite angles equals the measure of an exterior angle. The Exterior Angle is the angle formed by any side of a shape and a line drawn from the opposite side. Another example: When we add up the Interior Angle and Exterior Angle we get a Straight Angle (180°), so they are "Supplementary Angles". An exterior angle of the triangle is a nonstraight angle (one that is not just an extension of a side) outside the triangle but adjacent to an interior angle (Figure 1 ).

Two sides of an isosceles triangle measure 8 inches and 3 inches. What must be the length of the third side of the triangle?
Answer:
8
Step-by-step explanation:
The triangle is isosceles so the answer is either 3 or 8.
You might think there are 2 answers. There are not. The base is 3 inches and the two equal sides are 8 inches a piece.
If you say that there are 2 sides of 3 inches each, they add up to 6. They can't. Six is much smaller than 8 and so two sides of 3 don't even cover up the 8, let alone make a triangle.

Amelia took a taxi from her house to the airport. The taxi company charged a pick-up fee of $4.60 plus $0.50 per mile. The total fare was $13.60, not including the tip. Write and solve an equation which can be used to determine
m
m, the number of miles in the taxi ride.
Solution: the number of miles in the taxi ride.= 180 miles
Miles : A unit of length equal to exactly 1.609344 kilometers.
Also equal to 1,760 yards or 5,280 feet.
The average walking speed is 3 miles per hour (so it takes about 20 minutes to walk 1 mile).
The taxi company charged a pick-up fee of $4.60
The taxi company charged $0.50 per mile.
The total fare was $13.60
The total fare = pick-up charged + traveling charged
the number of miles in the taxi ride = m
$13.60= $4.60 + m x $.50
$13.60-$4.60 = $.50m
9 =.50 m
9 /.50 = m
900/5 = m
180 = m
the number of miles in the taxi ride.= 180 miles

nearest tenth.

about
in?
The surface area of the outside of the trash can is approximately 616.8 square inches.
How can we calculate the surface area of the outside of the trash can?To calculate the surface area of the outside of the trash can, we need to consider its shape. Assuming the trash can is a cylinder without a lid, we can break down the calculation into three parts: the lateral surface area of the cylinder, the top circle, and the bottom circle.
First, let's calculate the lateral surface area. The formula for the lateral surface area of a cylinder is given by 2πrh, where π is a mathematical constant approximately equal to 3.14159, r is the radius of the circular base, and h is the height of the cylinder. Since we are not given the height of the trash can, let's assume it to be 14 inches. We'll also assume the radius to be half of the diameter of the circular base, so the radius is approximately 7 inches. Plugging these values into the formula, we get a lateral surface area of approximately 2(3.14159)(7)(14) = 615.7 square inches.
Next, let's calculate the surface area of the top circle. The formula for the area of a circle is given by πr^2, where r is the radius of the circle. Using the radius of 7 inches, the area of the top circle is approximately (3.14159)(7^2) = 153.9 square inches.
Finally, let's calculate the surface area of the bottom circle, which is the same as the top circle. Therefore, the area of the bottom circle is also approximately 153.9 square inches.
To find the total surface area, we sum up the lateral surface area, the top circle area, and the bottom circle area: 615.7 + 153.9 + 153.9 = 923.5 square inches.
Rounded to the nearest tenth, the surface area of the outside of the trash can is approximately 923.5 square inches.

Pythagorean theorem equation.
O Divide both sides of the equation by two, then
determine the principal square root of both sides of the
equation.
Determine the principal square root of both sides of
the equation.
O Divide both sides of the equation by 2.
The hypotenuse is \(c = a\sqrt{2}\) times the length of each leg 'a'. Triangle XYZ is a isosceles right triangle, therefore the Pythagoras theorem becomes and this can be evaluated by using properties of isosceles triangle.
According to the statement
we have given that a theorem and we have to prove it.
So, For this purpose,
The given information is :
Isosceles triangle XYZ where \(Angle X = 45^{0}\) \(Angle Y = 45^{0}\) \(Angle Z = 90^{0}\)
Let the sides of triangle XYZ be a, b, and c. Then side XY = c, YZ = b and ZX = a.
Now, it is given that triangle XYZ is isosceles triangle therefore, the shorter sides must be equal that is, a = b.
Now use Pythagoras theorem
\(a^{2} + b^{2} = c^{2}\)
But here a= b then the equation become
\(a^{2} + a^{2} = c^{2}\)
Then after solving it become
\(2a^{2} = c^{2}\)
And here we have to find the value of the hypotenuse,
so we solve it for c.
Then
\(c = a\sqrt{2}\)
From this it is clear that the
it can be concluded that the hypotenuse is times the length of each leg 'a'.

12 O 44 Madeline, Tyra, and Imogen are helping consolidate leftover pizza slices after a party. Each one of them has a box with leftovers. Madeline says the leftover slices in her box form a 203° angle . Tyra says the leftover slices in her box form a 59 After hearing those descriptions from Madeline and Tyra, Imogen wonders if the leftover slices would all fit into one box (meaning one full circle of 360° or less). It is possible if the angle measure of her leftover slices is no larger than [Drop Down 1]. If each slice has an angle of 40 the maximum amount of slices Imogen can fit is [Drop Down 2]. 1 mron Down 11
Answer:
i. The angle measure of Imogen's leftover should not be larger than \(98^{o}\)
ii. The maximum number of slices that Imogen can fit is 2.
Step-by-step explanation:
The leftover in Madeline's box forms angle = 203°
The leftover in Tyra's box forms angel = \(59^{o}\)
Sum of angles formed = 203° + \(59^{o}\)
= \(262^{o}\)
Given that one box = 1 full circle of 360°. Then,
the angle formed by the leftover in Imogen's box = 360° - \(262^{o}\)
= \(98^{o}\)
Thus, the angle measure of Imogen's leftover slices should not be larger than \(98^{o}\).
If each slice has an angle of \(40^{o}\), the maximum number of slice that Imogen can fit = \(\frac{98}{40}\)
= 2 \(\frac{9}{20}\)
= 2.45
The maximum number of slices that Imogen can fit is 2.
