Answer:

c. Zhen spends 6 1/2 hours working per audiobook.

Step-by-step explanation:

The table below gives some completed audio lengths and the amount of time Zhen spends on the audiobook.

\left|\begin{array}{c|c}$Completed length of audiobook (hours) &$Working time (hours)\\---------&--------\\1&6\frac{1}{2} \\\\3\frac{1}{2}&22\frac{3}{4}\\\\7&45\frac{1}{2}\\\\10&65\end{array}\right|

We observe that from the table, in 6.5 hours, Zhen completes 1 audiobook.

In fact, across the table:

\dfrac{6\frac{1}{2}}{1}=\dfrac{22\frac{3}{4}}{3\frac{1}{2}}=\dfrac{65}{10}=6\dfrac{1}{2} $ hour per audiobook

Therefore, in this situation, 6.5 hours mean that Zhen spends 6.5 hours working per audiobook.

The correct option is C.

4 trillion pounds.

1 gigawatt-hour is equal to 1,000,000 kilowatt-hours.

Out of our 4,000,000 gigawatt-hours, 50% of it comes from coal; this is 2,000,000 gigawatt-hours.

2,000,000(1,000,000) = 2,000,000,000,000 (2 trillion) kilowatt-hours.

Since each kilowatt-hour is 2 lbs of carbon dioxide, 2 trillion * 2 = 4 trillion lbs of carbon dioxide.

A physical education class has three times as many girls as boys. During a class basketball game, the girls average 18 points ea
BigorU [14]
Let the number of girls be g and the number of boys be b.
b = 3g
Class average = class score/class size = 17
17 = (class score) / 3g + g
68g = class score
Class score = girls score + boys score
Girls average = girls score/g
girls score = 18g
68g = 18g + boys score
boys score = 50g
Boys average = 50g/3g
= 16.7

In a class of 30 students there are 17 girls. two students are picked randomly to represent the class in the SRC. determine the
Alla [95]

Answer:

See below in bold,.

Step-by-step explanation:

There are 30-17 = 13 boys in the class.

a.  Prob(First is a boy ) = 13/30 and Prob( second is a boy = 12/29).

As these 2 events are independent:

Prob( 2 boys being picked) = 13/30 * 12/29 =  26/145 or 0.179 to the nearest thousandth.

b. By a similar method to a:

Prob ( 2 girls being picked) =  17/30 * 16/29 = 136/435 = 0.313 to the nearest thousandth.

c.  Prob (First student is a boy and second is a girl) =  13/30 * 17/29 = 221/870.

Prob ( first student is a girl and second is a boy)  = 17/30 * 13/29 = 221/870

These 2 events are not independent so they are added:

Prob( one of the students is a boy)  = 2 (221/870 =  221/435 = 0.508 to the nearest thousandth.

Find the value of x and the value of y. 60 30 6
allochka39001 [22]

Answer:

  • The longest side, which is the opposite side of a right angle is the hypotenuse ( h ).

  • The opposite is the side opposite the angle involved and it is called the Perpendicular ( p ) .

  • The adjacent is the side next to the angle involved ( but not the hypotenuse ) and it is called the base ( b )

\large{ \tt{❃ \: TAKING  \: \angle \: \: A \: AS \: A \: ANGLE \: OF \: REFERENCE :  }}

  • Here , Perpendicular ( p ) = 6 , hypotenuse = y and now we're going to find the value of y first : We know :

\large{ \tt{❁ \: sin \:  60 \degree =  \frac{perpendicular}{hypotenuse} }}

\large{ \tt{➝ \:  \frac{ \sqrt{3} }{2} =  \frac{6}{y}  }}

\large{ \tt{➝ \sqrt{3}y = 6 \times 2 }}

\large{ \tt{➝ \:  \sqrt{3} \: y = 12 }}

\large{ \tt{➝ \: y=  \frac{12}{ \sqrt{ 3} } }}

\boxed{ \large{ \tt{➝ y = \: 4 \sqrt{3} }}}

\large{ \tt{❇ \: TAKING  \: \angle \: B \: AS \: THE \: ANGLE \: OF \: REFERENCE}} :

  • Here - Perpendicular ( p ) = x , hypotenuse = y = 4 √ 3 and Now , we're gonna find the value of x :

\large{ \tt{❊ \: sin  \: 30 \degree =  \frac{perpendicular}{hypotenuse} }}

\large{ \tt{⟶ \:  \frac{1}{2} =  \frac{x}{4 \sqrt{3} }  }}

\large{ \tt{⟶ \: 2x = 4 \sqrt{3} }}

\large{ \tt{⟶ \: x =  \frac{4 \sqrt{3} }{2} }}

\boxed{\large{ \tt{⟶ \: x = 2 \sqrt{3} }}}

\boxed{  \large{ \tt{❈ \:  OUR \: FINAL \: ANSWER :  \boxed{ \tt \: x = 2 \sqrt{3}   \: \: y = 4 \sqrt{3} }✓}}}

  • And we're done! Hope I helped! Let me know if you have any questions regarding my answer and also notify me , if you need any other help ! :)
