Answer:

The required number which is a multiple of 10 is 20.

Step-by-step explanation:

1. We have to divide 4200 by a number which is a multiple of 10.

Let us assume that the number is 20, which is a multiple of 10.

Now, after division the quotient will be $\frac{4200}{20} =210$ .

2. We have to check whether the quotient is multiple of 10 or not.

Here, the quotient is 210 which is a multiple of 10.

Hence, the required number which is a multiple of 10 is 20. (Answer)

Write the 2 digit number that matches the clue

Wittaler [7]

You can figure this out by setting up an equation and make

x= tens digit
y= ones digit

y + 8 =x (tens digit 8 more than ones)

also we know that

y>0
x>0

since the 10s digit and 1s digit cannot be more than one number, we can say

0 < y > 10
0 < x > 10

since x has to be greater than 0 but less than 10, there is only one number that would fit into the equation for y

2 + 8 = 10
(y cannot equal 2 because than x is equal to 10 and it must be less than)

1 + 8 = 9
( y can be 1 since x is less than 10)

so it would be
y= 1
x= 9

the number would be 91

hope this helped!

Suppose you have 18 objects (10 of type A, 5 of type B, and 3 of type C). Objects of type A are indistinguishable from each othe

Paladinen [302]

Answer:

$\binom{18}{5}= 8568$

Step-by-step explanation:

Note that we have in total 18 items. Even though we are given information regarding the amounts of items per type, the general question asks the total number of ways in which you can pick 5 out of the 18 objects, without any restriction on the type of chosen items. Therefore, the information regarding the type is unnecessary to solve the problem.

Recall that given n elements, the different ways of choosing k elements out of n is given by the binomial coefficient $\binom{n}{k})$ .
