Answer:
?=9
Step-by-step explanation:
We have a special right triangle, the 45-45-90 triangle.
In a 45-45-90 triangle, the side lengths are x, and the hypotenuse is x√2.
Since we know that the side length is 9, this means that:

The ? is 9.
Answer:
1. +3=5.
2. x = x + 1.
3. x = x + 1.
Step-by-step explanation:
Hope these are good! :) Have a nice day!
If two ratios have the same value when simplified, then they are called Equivalent Ratios.
Equivalent ratios can be obtained by multiplying or dividing both sides by the same non-zero number.
As we want 3 equivalent ration in higher terms we will multiply it
4 : 7
by multiply with 2
4* 2 : 7* 2
8 : 14
by multiply with 3
4* 3 : 7* 3
2 : 21
by multiply with 4
4* 4 : 7* 4
16 : 28
you can multiply with any nonzero number
Hope this helped!
Have a great day!
Using the combination formula, it is found that he can make 4 different stacks.
The order in which the balls are selected is not important, as stated in the problem. hence the <em>combination formula</em> is used to solve this question. If the order was important, then the permutation formula would be used.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

In this problem, he has four flavors, and will choose three of them for the stacks, hence the number of different stacks is given as follows:

He can make 4 different stacks.
