The problem at hand deals with rotational motion. As defined, 1 revolution is 2 π radians. Using this to convert the given 240 revolutions per minute:
(240 rev/ min)(2 π radians/rev) = 480 π radians per minute
This is the 3rd option in the given problem
Flip the second fraction and change the fraction into multiplication
Also, change 2 1/2 into a improper fraction
2 1/2 = 5/2
(5/2)/(5/8) becomes 5/2 x 8/5
Multiply across
5 x 8 = 40
------- -----
2 x 5 = 10
Simplify 40/10
40/10 = 4
4 is your answer
hope this helps
Anita's speed rounded to the nearest hundredth is 0.28. The first 7 in the number 0.277 is the hundredths place. You look at the second 7 and you can see that 7 is greater than 5. So the answer is 0.28.
2, 5 is the correct answer (I’m pretty sure)
Answer:
<h2>1/5</h2>
Step-by-step explanation:
The sample space for pens is
5 red pens, 6 blue pens, 3 black pens,(5+6+3)= 14pens
The sample space for paper is
4 silver paper clips and 16 white (4+16)=20 papers
The probability of selecting a black pen and white paper
Pr(black pen)*Pr(white paper)
=3/14*16/20
=48/280
= 14/70
= 2/10
= 1/5
