What are prime numbers?
The numbers which are only divisible by 1 and the number itself.
What is prime factorisation?
Splitting the numbers into prime numbers, such that their product result the number itself.
First eliminate the prime numbers, 31,37
Remaining: 32,33,34,35,36,38,39
32=2x2x2x2x2
33=3x11
34=17x2
35=3x7
36=2x2x3x3
38=19x2
39=13x3
so, 33,34, 35,38,39
Therefore, 5 nnumbers between 30 and 40 are the product of two prime no.s

25% of Mr. Foster's class chose an amber background for their school picture. If 6 students chose an amber background, how many students are in Mr. Foster's class?
Answer:
24 studentsStep-by-step explanation:
25% of a hundred is one-fourth and because there are six students in a fourth of the whole we are multiplying four and six. 6x 4 is 24.
The percentage is calculated by dividing the required value by the total
value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
25% = 6 students
100% = 24 students
The total number of students in Mr. Foster's class is 24.
What is a percentage?The percentage is calculated by dividing the required value by the total
value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of students who chose an amber background = 6
25% of Mr. Foster's class chose an amber background for their school picture.
This means,
25% = 6
The total number of students = 100%
Now,
25% = 6 students
Multiply 4 on both sides.
4 x 25% = 4 x 6 students
100% = 24 students
Thus,
The total number of students in Mr. Foster's class is 24.

an old treasure map has the following instructions stand next to the black rock and face west. Walk 20 yards and then turn 90 degrees clockwise. Walk another 10 yards and then turn 45 degrees anticlockwise. Walk another 15 yards, reverse your directions and walk 5 yards back. Turn 135 degrees clockwise and walk another 10 yards. In which direction are you now facing?
Answer:
West.
Step-by-step explanation:
An old treasure map has the following instructions: stand next to the black rock and face west. Walk 20 yards and then turn 90 degrees clockwise. Walk another 10 yards and then turn 45 degrees anticlockwise. Walk another 15 yards, reverse your directions and walk 5 yards back. Turn 135 degrees clockwise and walk another 10 yards. To determine in which direction you are now facing, the following logical reasoning must be carried out:
You start by walking 20 yards west, then turning 90 degrees clockwise, turning south. Then you walk 10 yards and turn counterclockwise 45 degrees, to the southwest. Later, you walk another 15 yards, turn the direction to the northeast, and walk 5 more yards. From the northeast turn 135 degrees clockwise to the west and walk 10 yards. Thus, the final sense in which the person is walking is to the West.
Thus the approach above is correct.

Given tan0 = 7/24 use the Pythagorean theorem to find the value of sin 0
Answer:
Step-by-step explanation:
Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.
tan(x) = 7/24
sin(x)/cos(x) = 7/24
sin(x) = 7/√(7²+24²) = 7/√625 = 7/25

Charlotte walks home from school every day at a rate of
4 miles per hour. It takes her 30-minutes to reach
home. Her brother, Noah, runs home from the same
school every day at a rate of 6 miles per hour. How
many fewer minutes does it take Noah than Charlotte
to reach home from school each day? Be sure to
SHOW your WORK!
Answer:
Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.
Step-by-step explanation:
Since Charlotte walks home from school every day at a rate of 4 miles per hour and it takes her 30-minutes to reach home, while her brother, Noah, runs home from the same school every day at a rate of 6 miles per hour, to determine how many fewer minutes does it take Noah than Charlotte to reach home from school each day the following calculation must be performed:
Charlotte:
4 mph = 4/60 = 0.0666 miles per minute
0.0666 x 30 = 2 miles
So the distance from the school to her house is 2 miles
Noah:
6/60 = 0.1 mile per minute
2 / 0.1 = 20
Thus, Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.

anathematic progression consists of 37 terms the sum of the first day of it is 12 and sum of its last three terms is 318 then find the last and first two terms of the progression
Answer:
Let the first term and the common difference of the A.P are a and d respectively.
Since the A.P contains 37 terms. So, the middle most term is (37+1)/2 th term = 19th term.
Thus, three middle most terms of this A.P.are 18th, 19th and 20th terms.
Given a 18 + a 19 + a 20 = 225
⇒ (a + 17d) + (a + 18d) + (a + 19d) = 225
⇒ 3(a + 18d) = 225
⇒ a + 18d = 75
⇒ a = 75 – 18d … (1)
According to given information
a 35 + a 36 + a 37 = 429
⇒ (a + 34d) + (a + 35d) + (a + 36d) = 429
⇒ 3(a + 35d) = 429
⇒ (75 – 18d) + 35d = 143
⇒ 17d = 143 – 75 = 68
⇒ d = 4
Substituting the value of d in equation (1), it is obtained
a = 75 – 18 × 4 = 3
Thus, the A.P. is 3, 7, 11, 15 …
