Answer:
5.2%
Step-by-step explanation:
Volume of cylinder= πr²h
In Container A,
D= 18ft, r=18/2=9ft, h=15ft
volume= 22/7 × 9² × 15
= 26730/7 cubic ft.
In Container B,
D=16ft, r= 16/2=8ft, h=18ft
volume= 22/7 × 8² × 18
= 25344/7 cubic ft.
percent of amount of water left in Container A= percent of container A that is full after pumping
Amount of water left in Container A,
26730/7 - 25344/7 = 1386/7
Therefore, % of container A that is full= 1386/7 ÷ 26730/7 × 100
(1386×7×100)/(7×26730)= 5.185
To the nearest tenth= 5.2%
Answer:
P(both are red) = 5/18
Step-by-step explanation:
total counters = 9
red counters = 5
P(both red) = P(R1) n P(R2)
5/9 * 4/8 =5/18
5/9 because the red counters are 5 and the total number of counters are 9.
I multiplied by 4/8 because, after selecting the first red counter without replacement, the remaining is 4 and the total decreases to 8.
Answer:
-25
Step-by-step explanation:
2a² - 5a + 4, for f(-3)
2(-3)² -5(-3)+4
2*(-27)+15+4
-54+19
= -25
You would place it like this: 15.408
