How many 4-digit multiples of 21 and 15 are there and 4-digit multiples of either 21 or 15 are there?
salantis [7]

Answer:

943

Step-by-step explanation:

21| 1000

   | ----------

       47 | 13

21-13=8

1000+8=1008

21|9999

  |---------

     476|3

9999-3=9996

1008,1029,...,9996

let n be number of terms

a=1008,d=21,l=9996

9996=1008+(n-1)21

9996-1008=(n-1)21

8988=(n-1)21

n-1=8988/21

n-1=428

n=428+1=429

again 15|1000

            |---------

                66|10

15-10=5

1000+5=1005

15|9999

  | ---------

      666|9

9999-9=9990

1005,1020,...,9990

a=1005,d=15,l=9990

let n be number of terms.

9990=1005+(n-1)15

9990-1005=(n-1)15

8985=(n-1)15

n-1=8985/15

n-1=599

n=599+1=600

21=3×7

15=3×5

L.C.M.=3×5×7=105

105)1000(9

      -945

     ____

         55

105-55=50

1000+50=1050

105)9999(

     -945

   ---------

         549

       - 525

        -------

            24

        -------

9999-24=9975

1050,1155,...,9975

let n be number of terms.

d=105

l=a+(n-1)d

9975=1050+(n-1)105

9975-1050=(n-1)105

8025=(n-1)105

n-1=8925/105

n-1=85

n=85+1=86

so there are 86 multiples of 21 and 15

(A∪B)=A+B-(A∩B)

multiples of 21 or 15=429+600-86=1029-86=943

Are points A, C, D, and F coplanar? Explain.
tatiyna
Answer: Choice B) 

The points A, C and D form a triangle which is the front face you see in the pyramid. Point F is not on this triangle at all. Point F is towards the back at the base of the pyramid away from this front face. So we consider A,C,D,F collectively as a whole to be not coplanar. If we ignored the point F, then we can say that A,C,D are coplanar.

List the next four multiples of the unit fraction 1/2 4th grade
OleMash [197]
<h2>The next four multiples of the unit fraction \dfrac{1}{2} are</h2><h2>\dfrac{2}{2} ( 1), \dfrac{3}{2}, \dfrac{4}{2} (2) and \dfrac{5}{2}.</h2>

Step-by-step explanation:

We have:

The unit fraction = \dfrac{1}{2}

To find, the next four multiples of the unit fraction \dfrac{1}{2} = ?

∴ The next four multiples of the unit fraction \dfrac{1}{2}

The first multiple = \dfrac{1}{2}\times 2= \dfrac{2}{2} =1

The second multiple = \dfrac{1}{2}\times 3= \dfrac{3}{2}

The third multiple = \dfrac{1}{2}\times 4= \dfrac{4}{2} =2

The fourth multiple = \dfrac{1}{2}\times 5= \dfrac{5}{2}

∴ The next four multiples of the unit fraction \dfrac{1}{2} are

\dfrac{2}{2} ( 1), \dfrac{3}{2}, \dfrac{4}{2} (2) and \dfrac{5}{2}.
