Ben has 2 identical pizzas.
Varvara68 [4.7K]
Let the weight if a whole pizza be x grams

Then 1/4 of a pizza weighs x/4  grams and one eighth weighs x / 8.  The difference is 32 grams so we can make the following equation:-

x/4 - x/8  = 32
x / 8  = 32
Multiplying both sides by 8:-

x = 8*32 =  256 

Answer is 256 grams.

The team mascot shoots a rolled T-shirt from a special T-shirt cannon to a section of people in the stands at a basketball game.
Svet_ta [14]
For this parabola we have:
f ( 0 ) = 8
and : f ( 1 ) = 24
In the first equation ( A) :
f ( 0 ) = - 16 * ( 0 - 1 )² + 24 = - 16 * 1 + 24 = 8 ( correct )
f ( 1 ) = - 16 * ( 1 - 1 )² + 24 = 24  ( correct )
For B:
f ( 0 ) = - 16 * ( 0 + 1 )² + 24 = - 16 + 24    = 8  ( correct )
f ( 1 ) = - 16 * ( 1 + 1 )² + 24 = - 16 * 4 + 24 = - 64 + 24 = 40 ( false )
For C:
f ( 0 ) = - 16 * ( 0 - 1 )² - 24 = - 16 - 24 = - 40 ( false )
f ( 1 ) = - 16 * ( 1 - 1 )² - 24 = - 24  ( false )
For D:
f ( 0 ) = - 16 * ( 0 + 1 )² - 24 = - 16 - 24 = - 40 ( false )
f ( 1 ) = - 16 * ( 1 - 1 )² - 24 = - 24   ( false )
Answer:
A )  f ( t ) =  - 16 * ( t - 1 )² + 24

The Hamilton Brush Company issued 2,500 shares of common stock worth $100,000.00 total. What is the par value of each share?
alexandr1967 [171]
What we know here is that all 2500 shares together are worth 100 000 dollars in total. (it's 100 000.00 actually, but we can ignore the part after the point, as it's equal to 0).

This means that each of the shares is valid the whole sum divided by the number of shares, that is:
\frac{100000}{2500} = \frac{1000}{25} =40
(first i divided both denominator and numerator by 100)
So each value is worth 40 dolars.
