Answer:
35
Step-by-step explanation:
Law of cosines
c^2=a^2+b^2-2ab(cos(A))
14^2=11^2+8^2-2(11)(8)Cos(A)
A=93.5833
Law of Sines
Sin(A)/a=Sin(B)/a
Sin(93.5833)/11=Sin(B)/8
B=34.7719
Answer:
472800 or 4.728x10^5
Step-by-step explanation:
first you would slove (4.7x10^5) and (2.8x 10^3). Which would be 470000 and 2800. Then add the two together to get 472800. And if they want you to put it back into scientific notation then it would be 4.728x10^5
Answer:
D. and .
Step-by-step explanation:
We have been given that one a recent trip, Cindy drove her car 290 miles, rounded to the nearest 10 miles, and used 12 gallons of gasoline, rounded to the nearest gallon.
The range of miles driven would be between because number of miles in rounded to nearest 10 miles.
The range of gallons of gasoline would be because number of gallons of gasoline in rounded to nearest gallon.
To find mileage, we will divide number of miles by number of gallons.
The possible number of gallons of gasoline will be 12.5 gallons for 285 miles to get the minimum number of miles.
Similarly, the possible number of gallons of gasoline will be 11.5 gallons for 295 miles to get the maximum miles.
Therefore, our required range would be and .
