The answer to this is 756 hours. Because first you must multiply the number of miles each flight is x the miles per minute. Next you multiply that answer by the number of trips. The answer would be how many minutes, but the question asks "how many hours", and there's 60 minutes in an hour so divide that answer by 60 and that will equal 756 hours.

10. 10. If AB bisects CAF, and m&lt;EAF = 72°,<br>then the m&lt;BAF =​
never [62]

The measure of ∠BAF is 54°.

Solution:

DF and CE are intersecting lines.

m∠EAF = 72° and AB bisects ∠CAF.

∠EAF and ∠DAC are vertically opposite angles.

Vertical angle theorem:

<em>If two lines are intersecting, then vertically opposite angles are congruent.</em>

∠DAC ≅ ∠EAF

m∠DAC = 72°

<em>Sum of the adjacent angles in a straight line = 180°</em>

m∠DAE + m∠EAF = 180°

m∠DAE + 72° = 180°

Subtract 72° from both sides.

m∠DAE = 108°

∠CAF and ∠DAE are vertically opposite angles.

⇒ m∠CAF = m∠DAE

⇒ m∠CAF = 108°

AB bisects ∠CAF means ∠CAB = ∠BAF

m∠CAB + m∠BAF = 108°

m∠BAF + m∠BAF = 108°

2 m∠BAF = 108°

Divide by 2 on both sides, we get

m∠BAF = 54°

Hence the measure of ∠BAF is 54°.

I need some DETAILED examples of Dividing Integers! Urgent, pls help ASAP!
vfiekz [6]

Here are some examples:

Integers are positive and negative numbers, but dividing integers are dividing positive and negative numbers:

Remember these rules:

  1. Negative divided by a negative equals a positive.
  2. Negative divided by a positive equals a negative.
  3. Positive divided by a positive equals a positive .

Examples:

  • -4 \div 2 = -2
  • -4 \div -4 = 1
  • 4 \div 2 = 2

Hope this helps!

In the function ƒ(x) = x2 + x + 1, which of the following represents the output value? Select one or more: A. f(x) B. x2 C. x D.
kakasveta [241]

Answer:

The correct answer is f(x)

Step-by-step explanation:

The answer is f(x) because is the result of the quadratic sum, once the function is evaluated. Example:

Let be x= 2

Then f(2)= 4+2+1=7

Therefore the output is f(2) which is equal to 7.
