Answer:

280

Step-by-step explanation:

For example, if Justin Upton gets 155 hits in a season and has 554 at bats, his batting average would be 155/554, or .280. The batting average is usually represented not as a percentage (i.e. 28.0%), but instead as a decimal number with three places after the decimal. A batting average of 1.000 means that the player gets a hit every time he comes to bat, and an average of .000 means the player has no hits.

It should also be noted that not every time a batter comes to the plate counts as an at bat. Plate appearances that do not count as at bats include walks, hit-by-pitches, sacrifices, etc.

It takes 36 minutes to manually package 400 candles into boxes for shipment. When an automated packaging system works together w

Fittoniya [83]

Answer:

12 minutes

Step-by-step explanation:

Candles can be manually packed at the rate of ...

... (400 candles)/(36 minutes) = 11 1/9 candles/minute

The two systems together pack candles at the rate of ...

... (400 candles)/(9 minutes) = 44 4/9 candles/minute

Then the machine's packing rate is the difference between the total and the manual rates:

... machine rate = (44 4/9 candles/minute) - (11 1/9 candles/minute)

... = 33 1/3 candles/minute.

At this rate, the machine working alone can pack 400 candles in ...

... (400 candles)/(33 1/3 candles/minute) = (400/(100/3)) minutes

... = 400 × 3/100 minutes = 12 minutes

Sterre charges $35 to file tax returns, but files for free if she only needs the easiest form. Then she donates $2 to clean wate

borishaifa [10]

We have been given that Sterre charges $35 to file tax returns, but files for free if she only needs the easiest form. Also, she donates $2 to clean water projects per tax return she files.

Further we know that Sterre charged $7,245 and made a donation of $1,242 this year for the tax returns she filed.

Let x be the number of free income tax returns and y be the number of $35 income tax returns.

Therefore, we can set up:

$0\times x+35\times y=7245\Rightarrow 35y=7245\Rightarrow y=\frac{7245}{35}=207$

Since she donates $2 for each return that she files, therefore, we can set up:

$2(x+y)=1242\Rightarrow x+y=621\Rightarrow x+207=621\Rightarrow x=414$

Therefore,

Sterre filed 414 tax returns for free and filed 207 tax returns for $35.

What type of triangle has side lengths 12, 13, and 2√3?

Travka [436]

Answer:

The triangle is an obtuse scalene triangle

Step-by-step explanation:

we know that

if $c^{2}=a^{2}+b^{2}$ --------> is a right triangle

if $c^{2}>a^{2}+b^{2}$ --------> is an obtuse triangle

if $c^{2}$ --------> is an acute triangle

where

c is the greater side

we have

$c=13\ units$

$a=12\ units$

$b=2\sqrt{3}\ units$

$c^{2}=13^{2}=169$

$a^{2}+b^{2}=12^{2}+(2\sqrt{3})^{2}=156$

$c^{2}>a^{2}+b^{2}$ -------> is an obtuse triangle

Remember that

The given triangle has three different length side

Is a scalene triangle

therefore

The triangle is an obtuse scalene triangle
