here are some numbers 2 9 14 36 40 what number is a multiple of 12 which number is a prime number which number is a factor of 64

Answers

Answer:  36 is a multiple of 12

2 is a prime number.

2 is a factor of 64

Step-by-step explanation:

12 × 3 =36, so 12 is one of the factors.

2 is the only even prime number. All other even numbers are multiples of 2.

9 is not a prime number. 3 × 3 = 9

2 is a factor of 64.  2 × 32 = 64  None of the other numbers given can divide evenly into 64, so they are not factors of 64.

12. A cyclist travels 40 km at a speed of x km/h. Find the time
taken in terms of x. Find the time taken when his speed is
reduced by 2 km/h. If the difference between the times is
1 hour, find the original speed x.

Answers

Answer:

Step-by-step explanation:

distance = rate times time, so

           

           distance

time = --------------

               rate

Here the distance is 40 km and the rate is x.  Then

              40 km

time = --------------  =  (40/x) hr

             x km/hr

If the speed is reduced by 2 km/hr, we get:

              40 km                                            40 km                  40

time = -------------------------------  or time = ----------------------- = --------- hr

             (x km/hr - 2 km/hr)                      (x - 2) (km/hr)       x - 2

The difference between the times is:

 40          40

-------- - --------- = 1 hr          Solve this for the original speed, x

x - 2         x

40x - 40x + 80                                80

-----------------------  =  1 hr     or     ------------ = 1     or 80 = x^2 - 2x

     x(x - 2)                                     x(x - 2)

Rewriting this in standard quadratic form:  x^2 - 2x - 80 = 0

Here a = 1, b = -2 and c = -80, and so the discriminant b^2 - 4ac is:

(-2)^2 - 4(1)(-80) = 324

The solutions are:

   

      -(-2) ± √324       2 ± 18

x = -------------------- = ------------ = 1 ± 9, or 10 (discard the other root)

              2                      2

The original speed was 10 km/hr

the answer is 10 km/hr.

800 students attend Ridgewood Junior High School. 25% of students bring their lunch to school everyday. How many students brought their lunch to school on Thursday?
Insert the values given in the problem then scale up or down to find the missing value.

800 students attend Ridgewood Junior High School. 25% of students bring their lunch to school everyday.

Answers

To find the number of students who brought their lunch to school on Thursday, we can start by calculating 25% of the total number of students.

25% of 800 students is (25/100) * 800 = 200 students.

Therefore, 200 students brought their lunch to school on Thursday.
according to my understanding it’s 200

800*200= 2000
20000 divided by 10 =200

Answers

Answer:

70

Step-by-step explanation:

The sum of all the angles of a triangle is 180.

so 47 + 63 + x = 180

110 + x = 180

x = 180-110

x = 70

The sum of the angles in a triangle is 180°. Therefore the value of x in the triangle attached is 70°.

Understanding Angles in a Triangle

A triangle is a polygon with three sides, three angles, and three vertices (corners). It is one of the fundamental shapes in geometry and has several important properties.

Properties of Triangles

1. Interior Angles: The interior angles of a triangle always add up to 180 degrees. Each angle is measured in degrees, and the sum of all three angles is always a straight angle.

2. Exterior Angles: The exterior angle of a triangle is formed by extending one of its sides. The measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.

3. Side Lengths: In a triangle, the sum of the lengths of any two sides is always greater than the length of the third side. This property is known as the Triangle Inequality Theorem.

Answer:

Step-by-step explanation:

Basically what you are going to do is turn the 1/4 into 2/8

Then you are going to add all the fractions together so 5/8 has 2 dots so it is 10/8 do that for all the ones that have multiple dots then turn all of those into one big fraction and divided it by 2/8

1) 5/8+5/8+6/8+1 = 3 leave this for now

2) 9/8+9/8+9/8 = 3 3/8 leave this for now

3) 10/8+11/8 = 22/8

4) now add the final numbers 3+3 3/8 + 22/8 = 9 1/8

5) divide by 2/8 to get 36 1/2
