Rafael must choose a number between 67 and 113 that is a multiple of, 2,4, and 5 . Write all the numbers that he could choose.

skelet666 [1.2K]

First, find out what the greatest common factor is between 2, 4, and 5.

This is 20. So any number divisible by 20 is also divisible by 2, 4, and 5. 

Now we find the list of numbers that are multiples of 20 between 67 and 113. 

The solutions are: 

80 and 100.

The first five terms of an arithmetic sequence are shown below: 20, 17, 14, 11, 8, . . . Let n represent the term number and f(n

Leona [35]

Answer: 17 -3n

Explanation:

In the given arithmetic progression 20,17,14,11,8....

first term that is a = 20

common difference that is d= a2-a1 = 17-20 = -3

let n is the nth term

$a_{n}$ = a+(n-1)d

substituting the values of first, common,difference and n

$a_{n}$ =20+(n-1) (-3)

= 20 -3n+3

=23 -3n

for some reason i can never find the volume of a sphere and i know how to but can someone help me please?

Aneli [31]

Answer:

113.1

Step-by-step explanation:

$V=\frac{4}{3} r^3\\V=\frac{4}{3} (3)^3\\113.1=\frac{4}{3} (3)^3\\V= 113.1$

This is the formula you have to follow, finding the volume of objects is hard without the formula and it's just something you'll have to memorize. BUt just remember to plug in the radius which is 3 in this problem, into the volume formula: $V=\frac{4}{3} r^3$
