Circumference/Diameter = pi = 3.14
C/D = pi = 3.14
G=11 you add all the numbers together to get the correct number
The best option is the first one (Six yards of rope costs $5.50). It is the lowest unit cost.
<u>Step-by-step explanation:</u>
For the given question case, first we should compare the unit costs of the choices provided and evaluate the best option.
Choice 1:
Six yards of rope costs $ 5.50
![\frac{5.50 \text { dollar}}{6 \text { yard }}=0.9167\ dollar/yard](https://tex.z-dn.net/?f=%5Cfrac%7B5.50%20%5Ctext%20%7B%20dollar%7D%7D%7B6%20%5Ctext%20%7B%20yard%20%7D%7D%3D0.9167%5C%20dollar%2Fyard)
Choice 2:
Four yards costs $ 4.75
![\frac{4.75 \text { dollar}}{4 \text { yard }}=1.1875\ dollar/yard](https://tex.z-dn.net/?f=%5Cfrac%7B4.75%20%5Ctext%20%7B%20dollar%7D%7D%7B4%20%5Ctext%20%7B%20yard%20%7D%7D%3D1.1875%5C%20dollar%2Fyard)
Thus, the best choice is the first one. Because it is the lowest unit cost.
Namely, how many times 2/3 goes into 4, well, let's just divide them then
Answer:
24
Step-by-step explanation:
In a deck of 52 cards, there are 4 kings and 4 queens
Selection of 3 kings out of 4 = 4 C 3 = 4
Selection of 2 queens out of 4 = 6
So, total number of selections = 4 x 6 = 24
