An airplane flies with a constant speed of 620 miles per hour. How long will it take to
travel a distance of 310 miles? Give your answer in minutes or hours.
Answers
Answer:
30 minutes
Step-by-step explanation:
Alright lets start by laying out what the problem gives us :
A plane flies 620 mph.
It is asking how long it will take to travel 310 miles.
We need to give our answer in minutes or hours.
So lets take mph and look at the full meaning "Miles per hour"
An hour has 60 minutes in it.
So really it is saying miles per 60 minutes as well as miles per hour
So you could say the plane is traveling 620 miles every 60 minutes.
So now lets look at the number 310.
Just looking at it I can tell you that 310 looks very close to half of 620, in fact it is exactly half!
So lets divide the 620 mph by the 310 miles it is asking and we get 2! Proving that 310 is half of 620.
Alright now lets divide both the number of miles and number of minutes :
620 miles per 60 minutes
divided by 2 both miles and minutes
310 miles per 30 minutes
So this is your answer. After this you get that it would take 30 minutes to travel 310 miles in a plane going 620 miles per hour!
I hope this helps and I could help you understand it. :)

Step-by-step explanation:
Linear pairs are supplementary. Vertical angles are congruent. An angle is the sum of its parts.
(a) C: supplementary to 138°, 180° -138° = 42°
(b) O: congruent to 138°
(c) R: supplementary to 32°, 180°-32° = 148°
(d) H: congruent to 32°
(e) S: complementary to 28°, 90° -28° = 62°
(f) O: supplementary to 122°, 180° -122° = 58°
(g) W: congruent to 122°
(h) C: supplementary to 28°, 180° -28° = 152°
(i) I: supplementary to 60°, 180° -60° = 120°
(∠TSW) E: supplementary to a right angle: 180° -90° = 90°
(∠TSU) O: half the complement of 20°, (90° -20°)/2 = 35°
(∠USW) H: complement of ∠TSU, 90° -35° = 55°
(∠RSV) A: supplement of ∠VSW = 180° -35° = 145°
__
The desired order of the letters corresponds to the sequence of angles ...
122°, 55°, 58°, 35°, 62°, 120°, 90°, 148°, 71°, 152°, 138°, 145°, 42°, 32°

12 - 3 = 9
Answer:
p=-2
Step-by-step explanation:
Move the -3 to the other side by adding 3 on both sides:
-6p-3+3=9+3
The equation now looks like this:
-6p=12
Divide -6 on both sides:
-6p/-6=12/-6
The equation now looks like this:
p=-2 which is the answer

Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer: y = -4x
Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.

Step-by-step explanation:
Given

Consider the factors of the constant term (+ 80) which sum to give the coefficient of the x- term (+ 18)
The factors are + 10 and + 8 , since
10 × 8 = + 80 and 10 + 8 = + 18 , then
x² + 18x + 80 = (x + 10)(x + 8) ← in factored form
