<h2>It takes 3 hours to empty the tank when the pumping rate is 180 gallons per hour.</h2>
Step-by-step explanation:
The time t (in hours) that it takes a pump to empty a tank of water varies inversely with the pumping rate r (in gallons per hour).
where k is a constant.
It takes 9 hours to empty a tank of water when the pumping rate is 60 gallons per hour.
We need to find how long does it take to empty the tank when the pumping rate is 180 gallons per hour ( r = 180)
We have
It takes 3 hours to empty the tank when the pumping rate is 180 gallons per hour.
Sally types faster than sue per minute by 10 words. If you divide 3000 by 60 because there are 60 minutes in an hour you will get how many words she types a minute which would be 50.
Answer: Right ,vertical, supplementary
Step-by-step explanation:In the given figure the two rays are perpendicular.A line is said to be perpendicular to another line if the two lines intersect at a right angle.Thus <1 and <2 are Right angles.
The opposite angles formed by two intersecting lines are called vertical angles.<1 and <2 are on opposite sides of the two rays and hence form vertical angles.
The angles made at the intersection of the two rays are 90 degrees .So the sum of angles 1 and angle 2= 90+90=180 degrees.When two angles add to 180 degrees they are called supplementary angles .
Hence <1 and <2 are Right ,vertical, supplementary angles.
A
substitute each point into the inequality and check validity of solution
A (4, 4)
4 ≤ 16 - 12 + 2 ⇒ 4 ≤ 6 → True hence valid solution
B (3, 3 )
3 ≤ 9 - 9 + 2 ⇒ 3 ≤ 2 → False hence not valid
C (1, 1 )
1 ≤ 1 - 3 + 2 ⇒ 1 ≤ 0 → False hence not valid
D (2, 2 )
2 ≤ 4 - 6 + 2 ⇒ 2 ≤ 0 → False hence not valid
5/8 = 0.625 = 62.5%
If 62.5% were glazed then you must find 62.5% of 24.
Equation…
x=0.625(24) = 15
if each costs $0.84 cents plus tax then you will multiply by 15.
15 x .84 = 12.6
The total cost was $12.60
