jeff wants to buy a phone card for long distance calls. he can buy a 200-minute card for $10.00 or a 300-minute card for $12.00.

Alenkasestr [34]

200 min / $10.00 = 20 minutes / dollar

300 min / $12.00 = 25 minutes / dollar 

The cost of the 300 minute card is cheaper per minute and a better value. 

If you don't expect to use more than 200 minutes then save your money and buy the smaller card.

Triangle abc and xyz are congruent ,/_A is one half the size of /_B,/_y is 90° ./_c and /_z each have a measure of 45°.What is t

Rashid [163]

Answer:

∠a = 45°

Step-by-step explanation:

We are told that △abc and △xyz are congruent.

Thus;

∠a = ∠x

∠b = ∠y

∠c = ∠z

We are given;

∠y = 90°

Thus, ∠b = 90°

Now,we are told that ∠a is one half the size of ∠b.

Thus; ∠a = ½ × ∠b

∠a = ½ × 90

∠a = 45°

Mariana [72]

Answer:

The questions and problem can be chosen in 1260 ways.

Step-by-step explanation:

Given that, a physics exam consists of 6 open-ended problem and 9 multiple choice questions.

The order of choosing does not matter.

So,we use combination to find ways.

The ways to choose 6 multiple choice from 9 is= $^9C_6$

$=\frac{9!}{6!(9-6)!}$

=84

The ways to 2 open-ended question from 6 is= $^6C_2$

$=\frac{6!}{2!(6-2)!}$

=15

Since pick 6 multiple choice out of 9 and 2 open-ended question out of 6 both are independent we have multiply both to find required ways.

Total number of ways is =(84×15)

=1260.
