You want to distribute 7 candies to 4 kids. If every kid must receive at least one candy, in how many ways can you do this?
puteri [66]

Answer:

15

Step-by-step explanation:

lets begin to set up this question. i personally find questions like these easiest when i begin to set up ideas to help my brain process it better, for example:

person a

person b

person c

person d

we know that each (person) must receive at least 1 candy. we also know that we have 7 candies. therefore if we want do draw this out :

person a- 1

person b- 1

person c- 1

person d -1

notice that we now have given away 4 of the 7 candies. now we have 3 candies left. we can simply:

person a- 2

person b-2

person c-2

person d- 1

but, keep in mind that there are still many more ways that we can distribute the candies to other kids. the question we are asked is how may ways can we do this. since i have already illustrated the question, you can either learn how to put this into an equation, or experiment how many variations there are. the answer, either way is 15.

If the length and width of a rectangular solid are increased by 10% and the height is increased by 20%, by what percent is the v
9966 [12]
LWH=V

increasse by 10% means times 1.10
increase by 20% is times 1.20



L turns to 1.1L
W turns to 1.1W
H turns to 1.2H

(1.1L)(1.1W)(1.2H)=1.452LWH
so it is increased by 45.2%

Answer: Third option.

Step-by-step explanation:

To solve this exercise it is important to remember the following:

1) By definition, equivalent expression have the same value, but they look different.

2) The multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-

Then, given the following expression provided in the exercise:

=(8.4x+2.9)+(-3.7x+5)

You need to distribute the postive sign:

8.4x+2.9-3.7x+5

And finally, you must add the like terms:

=8.4x-3.7x+2.9+5=4.7x+7.9

As you can notice, the expression obtained matches with the expression shown in the third option.
