Does it have to be a certain age ??
Answer:
≈ 83.9 cm²
Step-by-step explanation:
<u>Given:</u>
- P = a+b+c = 44 cm
- a = 18 cm
- b = 12 cm
<u>Then:</u>
- c= P -(a+b) = 44 -(18+12) = 14 cm
<u>Area of the triangle is found by using Herons formula:</u>
where s = P/2 = 44/2 = 22 cm
- A = √22(22-18)(22-12)(22-14) = √22*4*10*8= √7040 ≈ 83.9 cm²
Answer:
Mean
Step-by-step explanation:
If Wanda has 80 baseball cards and Kyle has 110 baseball cards. Given that they know the total value of all their individual base ball cards, the worth of each baseball card will be derived by dividing the Total Worth of the cards by the number of cards. This is an example of Mean. Therefore they should use Mean to compare the worth of the cards.
Illustrative Example
If the Total Value of their cards are $500,
For Wanda, Value Per Card= $500/80 Cards =$6.25 per card
Similarly,
For Kyle, Value Per Card= $500/110 Cards =$4.55 per card
So we can see from this illustration whose card is with an higher price using the mean.
