♥ Solve:
(Arjun) 40*30=1200
(Dalia) 55*30=1650
Now subtract
1650-1200=450.
That means that Dalia will type 450 minutes more.
Final answer: 450
Answer:
D. 8 bottles
Step-by-step explanation:
one bottle of one is obviously $6.50
one bottle of two : $12.50 (1/2) = $6.25
one bottle of four: $26.00 (1/4) = $6.50
one bottle of six: $30.00 (1/6) = $5.00
one bottle of eight: $38.00 (1/8) = $4.75
8 bottles is the best buy
Answer:
reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Step-by-step explanation:
For the proof here kindly check the attachment.
We are given that. Also, the transversal is shown. Let us take the first case, that of and . Please note that all other proofs will follow in a similar manner.
Let us begin, please have a nice look at the diagram. We will see that and are vertically opposite angles. We know that vertically opposite angles are congruent. Thus, and are congruent angles.
=
Now, we know that and are alternate interior angles. We also, know that alternate interior angles are equal too. Thus, we have:
=
From the above arguments it is clear that:
= = .
Thus, =
We have proven the first instance. Please note that all other instances can be proved in a similar fashion.
For example, for and we can take and as vertically opposite angles thus making = . Now, and are alternate interior angles and thus and are equal. Thus, we have and .
