<u> 359.905 degrees</u> is the answer.

Step-by-step explanation:

when it comes to the hour hand it moves about 360 degrees in a 12 hour clock for instance let us take the time 6:15 then the calculation is

=(6+15/60) * 360÷12

= 187.5 degrees.

when it comes to the minute hand the minute hand travels 360 degrees for every 60 minutes in a 12 hour clock so if it is 5 mins past in the time 6:05 then it can be given as

15/60 * 360 = 90 degrees

Difference between the two hand can be  calculated by

(Angle turned by the hour hand) - (Angle turned by the minute hand)

<u>For a smaller angle let us take 12:01 </u>

= (12+1/60) * 360÷12

=360.5

for the minute hand

=1/60 = 0.595

(Angle turned by the hour hand) - (Angle turned by the minute hand)

= 360.5 - 0.595

=<u> 359.905 degrees</u>

A library has five copies of a certain textbook on reserve of which two copies (1 and 2) are hardcover books and the other three
Gre4nikov [31]

Answer and Step-by-step explanation:

(a) Since the student have to stop when he gets to w softcover book, then the sample space should always stop at either 3 or 4 or 5. If the students examines the books randomly and stops at a softcover book, here are the possible ways he could carry this out,

S = {3, 4, 5, 13, 14, 15, 23, 24, 25, 123, 124, 125, 213, 214, 215}

2. Since only one book is to be examined then the student must check only one softcover book and end the examining. To do this, either he examines just 3 or 4 or 5. Therefore,

A = {3, 4, 5}

3. We need to pick the possibilities from the sample space that shows that the examining ended at book 5. Therefore,

B = {5, 15, 25, 125, 215}

4. We need to pick possibilities from the sample space that shows that book 1 was not examined. Therefore,

C = {3, 4, 5, 23, 24, 25}

A ball is kicked into the air and follows the path described by h(t)= – 4.9t^2 + 6t + 0.6, where t is the time in seconds and h
Natali [406]
I'm going to do the calculus way because it's easier
max height,
take derititive of the equation

h'(t)=-9.8t+6
find what value of t makes it equal to 0
t=6/9.8
if we inputed it for t we get
h(6/9.8)=2.43673...

2.43673...>2.4 so we don't need to change anything

Solve this system of equations by using the substitution method. y=2x-5 6x+7=y
gogolik [260]

Answer:

x =  - 3 \: and \: y =  - 11

Step-by-step explanation:

L

since \: y = 2x - 5(equation \: 1) \:  \\

substitute \: for \: y \: in  \: equation \: 2 \:  (6x + 7 = y)

6x + 7 = y \\ 6x + 7 = 2x - 5 \\ collect \: like \: terms \\ 6x - 2x =  - 5 - 7 \\ 4x =  - 12 \\ x =  \frac{ - 12}{4}  \\ x =  - 3

substitute \: for \: x  in \: equation \: 1

y = 2x - 5 \\ y = 2( - 3) - 5 \\ y =  - 6 - 5 \\ y =  - 11
