To define a perpendicular rays, we first define a ray.
A ray starts from one point and extend it to form one direction.
If two lines or rays or line segments intersect at right angle (90°), then they are perpendicular.
In particular, Perpendicular rays are rays that intersect to form a right angle.
Four right angles are formed in the perpendicular rays.
Amount of water in the pool at the end of the day is 5457798.7 gallons
<u>Explanation:</u>
Given:
Initial amount of water in the pool = 45,000 gallons
Increase in amount = 0.75 in per minute
Time, t = 1 day
t = 24 X 60 min
t = 1440 min
So,
Increase in amount of water in 1 day = 0.75 in X 1440
= 1080 in
Volume of 1080 in of water = (1080 in)³
Volume from cubic inch to gallon = 5453298.7 gallon
Amount of water in the pool at the end of the day = 45000 + 5453298.7 gallon
= 5457798.7 gallon
If the plant grows 0.4 cm per week....in 3 weeks, it will have grown :
3 * 0.4 = 1.2 cm
3/7 * -2 1/5 = (turn ur mixed number into an improper fraction)
3/7 * - 11/5 = (now just multiply straight across)
(3 * -11) / (7 * 5) = -33/35 <====
