Answer:
75.06239187
Step-by-step explanation:
1/2bh= Area of a Triangle
6^2+b^2=8.5^2 because we are missing a side we need to use the pythagorean theorem.
36+b^2=72.25
b^2=36.25
b=6.02
6.02+19= base
25.02
Now area
1/2bh
1/2 (25.02*6)
25.02*6= 150.1247
150.1247/2= 75.06239187 is Area
The above decimals before area are rounded.
1 cm= 10 mm
7 cm= 70mm
difference between grasshopper and cockroach= 99mm - 70mm
= 29mm
Answer: i will put the answer as a comment but what are you rounding to
Step-by-step explanation:
Answer: Option D
D. $108
Step-by-step explanation:
We must calculate the expected cost per patient to use treatment method B.
The expected cost for a discrete random variable x is:

Where
is the cost associated with the probability 
In this case, the random variable x is represented by the cost of each treatment.
For treatment B there is a possibility that antibiotic 2 works, in that case the cost x would be $ 100 and 
There is also the possibility that it does not work, in this case the cost x would be $180 and the probability 
The expected cost is:

Answer:
3(2x+x²-2)
Step-by-step explanation:
12x+3x²-6-6x
collect like terms
6x+3x²-6
factor the expression
3(2x+x²-2)
