fgiga [73]
Part A:

Given that a<span> bag contains 10 white golf balls and 6 striped golf balls, the ratio of white to striped golf balls is 10 : 6 = 5 : 3.

Given that </span>a<span> golfer wants to add 122 golf balls to the bag, the of balls each he should add is given by:

5\left( \frac{122}{5+3} \right) \ : \ 3\left( \frac{122}{5+3} \right)=5\left( \frac{122}{8} \right) \ : \ 3\left( \frac{122}{8} \right) \\  \\ =5(15.25) \ : \ 3(15.25)=76.25 \ : \ 45.75 \\  \\ \approx76:46

Therefore, the golfer shold add 76 white golf balls and 46 striped golf balls.



Part B.

You did not indicate the scale factor.

Assuming the scale factor is given by D(o, k) where k can be any number, then the cordinate of the </span><span>coordinates of the image of the quadrilateral VWXY are given by:

V'(6k, 2k), W(-2k, 4k), X(-3k, -2k), Y(3k,-5k)

That is you multiply the scale factor to the coordinates of the preimage to get the coordinates of the image.

There are 12 cookies in a container. There are 12 containers packed in a box for shipping. There are 12 boxes loaded onto a ship
mamaluj [8]

Option A

Total number of cookies on a shipping truck when 12 boxes are loaded is 1728.

<u>Solution:</u>

Need to determine correct option of total number of cookies on the truck

From given information

Number of cookies in 1 container = 12  

Number of container in 1 box = 12  

So number of cookies in 1 box = number of cookies in 12 container  

\Rightarrow \text { Number of cookies in } 1 \text { box }=\text { number of cookies in } 1 \text { container } \times 12

=12 \times 12=144

Number of boxes loaded onto 1 shipping truck = 12  

So Number of cookies onto 1 shipping truck = number of cookies in 12 boxes

\Rightarrow \text { Number of cookies onto } 1 \text { shipping truck }=\text { number of cookies in } 1 \text { box } \times 12

=144 \times 12=1728

Hence total number of cookies on a shipping truch when 12 boxes are loaded is 1728. Thus option A is correct
