Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
Answer:
The probability is 0.081
Step-by-step explanation:
Here, we want to calculate the probability that the 3rd inspection will be defective.
What this means is that the first two would
not be defective.
Probability of having a defective DVD = 10% = 10/100 = 0.1
Probability of not having a defective DVD = 1 -0.1 = 0.9
So the probability of third being defective = Probability of first not defective * Probability of second not defective * Probability of third defective
= 0.9 * 0.9 * 0.1 = 0.081

<h3><u>Given</u><u> </u><u>Information</u><u>:</u></h3>
- <u>Diameter of can</u>:- 3.6 cm
- <u>Height of</u><u> </u><u>can</u><u>:</u><u>-</u> 6.4 cm
<h3><u>To</u><u> </u><u>Find</u><u> </u><u>Out</u><u>:</u></h3>
- <u>Volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>Can</u><u>.</u>
<h3><u>Solution</u><u>:</u></h3>
Radius = (Diameter/2)
ㅤㅤㅤㅤ3.6 cm/2
ㅤㅤㅤㅤ1.8 cm
<u>So</u><u>,</u><u> </u><u>Radius</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>soup</u><u> </u><u>can</u><u> </u><u>is</u> 1.8 cm.
Volume øf cylinder = Volume øf can
Volume of cylinder = π r²h
(π = 22/7)
(r = radius = 1.8 cm)
(h = height = 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7×(1.8 cm)²× 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7× 3.24 cm² × 6.4 cm
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 22/7 × 20.736 cm³
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= (456.192/7) cm³
ㅤㅤㅤㅤㅤㅤㅤㅤㅤ= 65.17 cm³
So, the Volume of the soup can is 65.17 cm³

Answer:
B (√6)/4
Step-by-step explanation:
The smallest multiplier that will make the denominator of the fraction into a perfect square is 2, so you have ...

_____
Answer choice D is also a correct rationalization of the denominator, but is not simplified as far as it can be. √24 = 2√6, so a factor of 2 can be cancelled from numerator and denominator, giving answer choice B.
