Answer:

I believe 408 minutes a day

Step-by-step explanation:

So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.

ex.

240/10 = 24

24x7=168

240+168= 408

to do with 100s like 73% then divide the whole by 100 :)

Which of the following can be used to explain a statement in a geometric proof? Check all that apply.
nikitadnepr [17]

The <em><u>correct answers</u></em> are:

A-theorem ; B-corollary ; C-Postulate ; and E-Definition.

Explanation:

In a proof, we are tasked with proving one statement using other information that has already been proven.

Theorems are statements that have already been proven, and are used to prove other statements.

A postulate is a statement that is assumed to be true, and is used to prove other statements.

A corollary is a direct consequence of a proven fact, and as such, are used to prove other statements.

A definition is an absolute truth, so it can also be used to prove another statement.
