Option B is correct as the shape lacks a right angle and its side lengths do not conform to the Pythagorean theorem, despite having two perpendicular sides.
What is a right-angled triangle?A right-angled triangle is a geometric shape that has one internal angle measuring exactly 90 degrees. This angle, known as the right angle, is formed by the intersection of two sides of the triangle.
The other two angles in the triangle are acute angles, which means they measure less than 90 degrees. The side opposite the right angle is called the hypotenuse, and it is the longest side in the triangle.
The other two sides are called the legs, and they form the right angle. The lengths of the legs and the hypotenuse of a right-angled triangle are related by the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the legs.

Derek sent a chain letter to his friends, asking them to forward the letter to more friends. The group of people who receive the email gains 9/10 of its size every week and can be modeled by a function, P, which depends on the amount of time, t (in weeks).
Derek initially sent the chain letter to 40 friends.
Write a function that models the group of people who receive the email t weeks since Derek initially sent the chain letter
Answer:
Step-by-step explanation:
P(t)= 40*1.9^t/3
A function that models the group of people who receive the email t weeks since Derek initially sent the chain letter is p(t) =[tex]40 + 12t[/tex] (in t weeks).
What is a function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The number of people who received letters three weeks later:
= [tex]40 + \frac{9}{10} \times40[/tex]
= [tex]76[/tex]
The number of people who received letters one week later:
= [tex]40+(\frac{9}{10} \div3)\times40[/tex]
= [tex]52[/tex]
The number of people who received letters t week later:
= [tex]40+(\frac{9}{10} \div3).t\times40[/tex]
= [tex]40 + 12t[/tex]
So, a function that models the group of people who receive the email t weeks since Derek initially sent the chain letter is p(t) = [tex]40 + 12t[/tex] (in t weeks).

Of 80 people attending a dance 28 dance with their hands touching the floor. If four people at the dance are selected at random, determine the probability that each of the 4 dance with their hands touching the floor.
`PLEASE HURRY ITS A QUIZ
Answer: The probability is 0.013
Step-by-step explanation:
Out of 80 people, 28 of them dance with the hands touching the ground.
Then, the probability of selecting at random someone that dances with the hands touching the floor is equal to the number of persons that dance in that way, divided by the total number of persons.
For the first selection, this is p1 = 28/80
now, the probability in the second selection will be 27/79, because we have selected 1 out of the 28 (and also 1 out of the 80)
for the third and the fourth we have:
p3 = 26/78
p4 = 25/77
Then the probability of the fourth events is equal to the product of the four probabilities:
P = (28/80)*(27/79)/(26/78)/(25/77) = 0.013
Answer:
The probability that each of the 4 dance with their hands touching the floor is 0.0129.
Step-by-step explanation:
There are a total of 80 people and out of them, 28 dance with their hands touching the floor. The probability of selecting a person who has their hands touching the floor while dancing can be computed as 28/80.
We are asked to computed the probability that four people are selected at random and all four of them dance with their hands touching the floor. The probability for selecting the first person is 28/80. For the second person, the total no. of people are now 79 and the people who can dance with their hands touching the floor are 27. So, the probability is 27/79. Similarly, for the third person, the probability is 26/78 and for the fourth person, the probability is 25/77.
So, the probability that all four people selected dance with their hands touching the floor is:
28/80 * 27/79 * 26/78 * 25/77 = 0.0129

Ben and Roberto each own stores that sell video games. A) Ben’s Game World is having a sale on video games. The store is offering a sale pack of 4 video games for $43.80. What is the unit price of a video game in the sale pack? What would 7 games cost at Ben's Game World? B) Roberto’s Electronics is also having a sale on video games. The unit price of any video game at Roberto’s Electronics is 3/5 of the unit price of a video game in the sale pack at Ben’s Game World. How much would it cost a customer for 7 video games at Roberto’s Electronics?
Ben- unit price is 10.95
7 games= 76.65
Roberto- unit price is 6.57
7 games= 45.99
The unit price of a video game at Ben's Game World is $10.95, and 7 games would cost $76.65. Video games at Roberto's Electronics would cost $6.57 per game after applying the discount, with 7 games totaling $45.99.
Explanation:The student has asked for help with finding the unit price of video games in a sale at Ben's Game World and comparing this to the cost of video games at Roberto's Electronics. We are given that Ben is selling a pack of 4 video games for $43.80. To find the unit price, we divide the total cost by the number of games.
Calculate the unit price of a video game at Ben's Game World by dividing the total pack price by the number of games in the pack: $43.80 / 4 games = $10.95 per game.To find the cost for 7 games at Ben's game store, multiply the unit price by 7: $10.95 * 7 games = $76.65.Roberto's Electronics sells video games at 3/5 the price of Ben's unit price. First, calculate this discounted unit price: $10.95 * (3/5) = $6.57.To find the cost for 7 games at Roberto's store, multiply this discounted unit price by 7: $6.57 * 7 games = $45.99.evaluate (tan 60)(cos 45)

The nth term of a sequence is n-4
a) Work out the first three terms of the sequence.
b) Work out the tenth term of the sequence.
Answer:
Step-by-step explanation:
nth term = n - 4
A) 1st term = 1 - 4 = -3
2nd term = 2 - 4 = -2
3rd term = 3 - 4 = -1
First three terms are: -3, -2, -1
b) tenth term = 10 - 4 = 6
a) The first three terms of the sequence are -3, -2, and -1.
b) The tenth term of the sequence is 6.
a) To find the first three terms of the sequence with the nth term given as n - 4, we can substitute the values of n from 1 to 3 into the formula:For n = 1:nth term = n - 4 = 1 - 4 = -3For n = 2:nth term = n - 4 = 2 - 4 = -2For n = 3:nth term = n - 4 = 3 - 4 = -1So, the first three terms of the sequence are: -3, -2, -1.b) To find the tenth term of the sequence, we can again use the formula with n = 10:nth term = n - 4 = 10 - 4 = 6So, the tenth term of the sequence is 6.For more questions on sequence -

The measure of angle M is_degrees.
Answer:
m=37
Step-by-step explanation:
The 2 angles are complementary, or add to 90 degrees. Wee know this because of the little square in the corner that indicates a right angle, which is equal to 90 degrees.
m+53=90
Solve for m by getting m by itself. To do this, subtract 53 from both sides to "reverse" the addition being done to m.
m+53-53=90-53
The 53s on the left cancel, and we are left with:
m=37
Answer:
M = 37°
Step-by-step explanation:
M + 53° = 90°
M = 90° - 53°

PLEASE HURRY!! I HAVE LIMITED TIME!! :)
Look at the attached picture⤴
Hope this will help u...
The length of the radius, r, is 21 cm. The correct answer is **c. 21 cm**.
Here's why:
- The circumference of a circle is calculated by the formula C = 2πr, where C is the circumference and r is the radius.
- We are given that the circumference of circle O is 42π.
Substituting the given value into the formula:
42π = 2πr
Dividing both sides by 2π:
r = 42π / 2π
Simplifying:
r = 21
Therefore, the length of the radius, r, is 21 cm.
Options a, b, and d are incorrect because they either involve taking the square root of the circumference directly (invalid formula for radius) or miscalculating the result of the division.

Answer:

Step-by-step explanation:
The formula relating force, mass, and acceleration can be solved for mass. This formula will apply to both problems. We'll use m for both "mass" and "meters". We presume you can avoid getting mixed up by understanding that meters is used in the context of acceleration: m/s².
F = ma
m = F/a . . . . . divide by a
__
15. m = (250 N)/(5 m/s²) = 50 kg
__
16a. m = (15 N)/(3 m/s²) = 5 kg
16b. m = (15 N)/(4 m/s²) = 3.75 kg
_____
Comment on units
Especially for physics problems, I like to keep the units with the numbers. It is helpful to remember that Newtons are equivalent to kg·m/s². So, dividing Newtons by acceleration in m/s² will give mass in kg. Since you're familiar with F=ma, it's not too hard to remember that the units of force (N) are the product of the units of mass (kg) and acceleration (m/s²).

The sum of the first 100 even natural numbers is
the sum of the first 101 odd
natural numbers.
Answer: The Answer is "less than"
Step-by-step explanation:
To find the sum of a series, you find the difference between the first and last term, multiply that by the number of terms, then divide by 2.
For the even numbers, 2 is the first term and 200 is the 100th term (because 2+(100-1)2 is equal to 200). So, (100(2+202)/2 = 10100.
For the odd numbers, 1 is the first term and 201 is the 101th term (because 1+(101-1)2 is equal to 201). So, (101(1+202))/2 = 10251.5.
10100<10251.5 so the sum of the first 100 even numbers is less than the sum of the first odd 101 numbers.
The sum of the first 100 even natural numbers is smaller than the sum of the first 101 odd natural numbers.
What is an even number?A number that is divisible by two into two equal whole numbers is called an even number. Even numbers are those that end in 0, 2, 4, 6, and 8.
The problem can be solved using the arithmetic sequence. The sum of the first 100 even numbers will be,
[tex]\text{Sum of first 100 even numbers} = \dfrac{100}{2} \times [2(2) +(100-1)2]=10,100[/tex]
The sum of the first 101 odd numbers will be,
[tex]\text{Sum of first 101 odd numbers} = \dfrac{101}{2} \times [2(1) +(101-1)2]=10,201[/tex]
Hence, the sum of the first 100 even natural numbers is smaller than the sum of the first 101 odd natural numbers.
