Which statements are true about the reflectional symmetry of a regular heptagon? Select two options.
A heptagon has all equal side lengths.
It has only 1 line of reflectional symmetry.
A line of symmetry will connect 2 vertices.
A line of symmetry will connect a vertex and a midpoint of an opposite side.
It has 7-fold symmetry.
A line of symmetry will connect the midpoints of 2 opposite sides.
A line of symmetry will connect a vertex and a midpoint of an opposite side, it has 7-fold symmetry.
What is Heptagon?A two-dimensional shape having seven sides and seven angles are called a heptagon. It is a member of the two-dimensional geometry polygon class. Polygons are closed geometric shapes with only straight edges. In Greek, "hepta" denotes seven, while "gonia" denotes an angle.
The true statements about the reflectional symmetry of a regular heptagon are:
A line of symmetry will connect a vertex and a mid-point of an opposite side,
it has 7-fold symmetry.The line of symmetry of a shape divides the shape into equal segmentsA regular heptagon has 7 sides. So, it has 7-fold symmetry
Also, the line of symmetry passes through the midpoint and meets the opposite vertex.

Tom took 1/2hours to clean the den. Then he took 2 1/8 hours to clean the bedroom. How much total time did Tom take to clean the two rooms?
Answer:
Step-by-step explanation:
First convert the mixed number into a fraction:2 1/8 = 17/8
And convert 1/2 to 4/8 for greatest common denominatorThen do fraction addition:4/8 + 17/8 = 21/8
Convert improper fraction to mixed number:21/8 = 2 5/8
Therefore, Tom took 2 and 5/8 hours to clean the two rooms
Answer: 2 5/8 hours ( 2 hours and 38 mins [rounded])
Step-by-step explanation: For the best experience, look at the attachment:
So, first I took the numbers and set up an addition problem. But we have a problem. They both don't have the same denominator. So first, we need to find a common denominator before we add. So, luckily we know that 2 is a factor of 8. So 1/8 would stay the same and we'd multiply the 2 by 4 to get the denominator, and 1 by 4 to get the denominator. Then, you'd add 2 1/8 to 4/8 to get 2 5/8. Also, I converted 5/8 of an hour to get 37.5 mins, so I rounded up to 2 hrs and 38 mins.

You roll a 6-sided die. What is P(3)
The probability of rolling a 3 on a fair 6-sided die that P(3) is 0.17.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
Since each side of the die is equally likely to land face up,
So the number of favorable outcomes n(E) = 1
And the total number of outcomes n(S) = 6
Thus, P(3) is the probability of rolling a 3 on a fair 6-sided die :
P(3) = n(E)/n(S)
P(3) = 1/6
P(3) = 0.17

The sequence of height of the ball after each bounce are in geometric sequence with ratio of 0.75.
What is Arithmetic Progression ?
Arithmetic progression can be defined as the sequence of numbers which has same difference between any consecutive numbers.
Given,
A ball is dropped from the height 160cm
And the ball loses 25% of its previous height after each bounce.
so,
for every bounce the height will be decreased by 25%
after first bounce , 160 - 160/4 = 120
after second bounce , 120 - 120/4 = 90
after third bounce , 90 - 90/4 = 67.5
The sequence could be 160,120,90,67.5 and soon
if a1 / a2 = a2/a3
it is said to be in gp
so a1/a2 = 120/160 = 0.75
a2/a3 = 90 / 120 = 0.75
Hence , we can say that the sequence is in gp with common ratio of 0.75

After a price was decreased by 15%, it became $2176. What would the price be if
the price was increased by 10% first, and then decreased by 25%?
This is due today, I REALLY NEED HELP!
Answer:
If the price was decreased by 15% and the price became $2176, the original price would be:
$2176 / (1 - 0.15) = $2176 / 0.85 = $2560
If we first increase the price by 10% and then decrease it by 25% we can use the following method:
Multiply the original price by 110% to increase it by 10%: $2560 * 1.1 = $2816
Multiply the increased price by 75% to decrease it by 25%: $2816 * 0.75 = $2,112
So the price would be $2,112 if the price was increased by 10% first, and then decreased by 25%.

What is tempreture?Temperature in mathematics is usually referred to as a measure of the average kinetic energy of the particles in a system. The higher the temperature of the system, the more energetic the particles are and the more likely they are to move around. Temperature is usually measured in Kelvin, Celsius, Fahrenheit, or Rankine.
The new temperature in Moscow is now +2 °C.
The temperature falls by 6 degrees Celsius from 4°C to -2°C. This drop in temperature is an example of how quickly the weather can change in Juneau. The city is located in Southeast Alaska, along the coast of the Gulf of Alaska. This means that it is often subject to sudden shifts in temperature and weather patterns due to its close proximity to the ocean. The high humidity and large temperature range make Juneau a great place for outdoor activities like kayaking, fishing and hiking. However, it's important to always be prepared for changes in the weather.

What is slope and intercept?In a linear equation, the slope (also called the gradient) is a measure of the steepness of the line, and the y-intercept is the point at which the line crosses the y-axis. The slope of a linear equation can be represented as m in the form of y = mx + b, where m is the coefficient of x, and b is y-intercept. The y-intercept is the point where the line crosses the y-axis, which can be represented by the value of b in the form of y = mx + b.

If the probability that the Islanders will beat the Rangers in a game is 33%, what is the probability that the Islanders will win exactly zero out of the three games in a series against the Rangers? Round your answer to the nearest thousandth
The probability that the Islanders will win exactly zero is 0.300763
How to determine the probability that the Islanders will win exactly zeroFrom the question, we have the following parameters that can be used in our computation:
Number of games = 3
Probability of winning = 33%
This means that
Probability of losing = 1 - Probability of winning
Substitute the known values in the above equation, so, we have the following representation
Probability of losing = 1 - 33%
Evaluate
Probability of losing = 67%
The probability that the Islanders will win exactly zero is calculated as
P = Probability of losing^3
So, we have
P = (67%)^3

P = 0.300763
