Hi there --
If a plane can climb 2,400 feet per minute, it will need 25 minutes to reach 60,000 feet. // By dividing 60,000 (the needed feet) by 2,400 (the amount of feet the plane can climb per/min) you get 25 (the amount of mins needed to climb 60,000 feet)
Hope this helps! Have a great day! :)
Using relations in a right triangle, it is found that:
sin(x) = cos(y) = 0.6.
Since angles x and y are complementary, we have that sin(x) = cos(y), that is, the ratio is of 1.
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
Applying the Pythagorean Theorem, the hypotenuse is given by:
h² = 3² + 4²
h² = 25
h = 25.
Hence, applying the definitions:
Since angles x and y are complementary, we have that sin(x) = cos(y), that is, the ratio is of 1.

Divide 15 by 40 to get the percent and that tells you that its 0.375 once you have that you move the decimal 2 spots to the left to get 37.5%
Answer:
See below.
Step-by-step explanation:
It isn't clear if the problem wants to know the number of video games sold, or the number remaining.
<h2><u>
Remaining Games</u></h2>
Let N be the number of video games in the store after d days. Assume none are replaced after they are sold.
N = 30 - 6d [Remaining games, N, are 30 minus the number of days, d, times 6 games/day] We need to also state 30 ≥ N ≥ 0. [No negative games are allowed. They are bad for morale].
<h2><u>
SOLD Games</u></h2>
Let N be the number of games sold over n days.
N = 6d [Games sold] Here, we need to state 0 ≤ N ≤ 30. [We can't sell more games than we have, unless you are a fast runner].
