Answer:
32.7°
Step-by-step explanation:
Use the formula for law of cosines, for this question we need so solve for angle B, so use...
b² = a² + c² - 2(a)(c)Cos B
We are given a, b, and c, so plug them in...
55² = 90² + 50² - 2(90)(50)Cos B
Now simplify...
3,025 = 8100 + 2500 - (9000)Cos B
-7,575 = -(9000)Cos B (subtract 8100 and 2500 from both sides)
0.841666667 = Cos B (divide both sides by -9000)
Cos^(-1) 0.841666667 = B (use cosine inverse function on calculator)
Answer:
B
Step-by-step explanation:
City X = 3 * 10^5 Given
City Y = 6 * 10^6
Times larger
6 * 10^6
3 * 10^5
Do the division
6*10^6/3^10^5 = 60 * 10^5/(3 * 10^5) Note 10^5 will cancel
60/3 = 20 City y is 20 times City x
Population Difference
6,000,000
300,000
5,700,000
Just from the numbers I've given you, A is incorrect. The answer is 20 not 2.
B is the answer
C is wrong. X is 5.7 million less.
D See the answer for C.
Hi there! :)
Answer:
Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:
Find the area of the base:
b = π(7)²
b = 49π
b = 153.86 mm²
Find the volume:
V = 1/3(153.86 · 7)
V = 1/3(1077.02)
V = 359.006 ≈ 359.01 mm³.
