Answer:
I think it's D
Step-by-step explanation:
Because all of them are true
Is this math? I'm sorry I don't get what formula I'm supposed to rewrite or -
Hey there! :)
Answer:
r ≈ 4.38 cm.
Step-by-step explanation:
Find the radius by working backwards using the equation A = πr²:
Given:
A = 60.24 cm²
π = 3.14
Plug these into the equation:
60.24 = 3.14r²
Divide both sides by 3.14:
19.185 = r²
Take the square root of both sides:
r ≈ 4.38 cm.
Using the combination formula, it is found that there are 84 ways to choose the three tiles.
The order in which the tiles are chosen is not important, hence the <em>combination formula</em> is used to solve this question.
<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, three tiles are chosen from a set of nine, hence:

There are 84 ways to choose the three tiles.

Yes,according to the law of Detachment
Step-by-step explanation:
According to the law of detachment, in mathematical logic two statements are true;
a) If p then q
b)p
The we can derive a third statement q
Given: If the power has been cut, then the refrigerator does not work
Let p be the statement 'the power has been cut' and q be the statement 'the refrigerator does not work' the the two statements can be written as
1) If p the q
2) p
we can conclude that q is true, the refrigerator does not work.
