1 light year = 9.46 x 10^12 km. Therefore how many light years = 5.9 x 10^13?. Do cross multiplication you'll get. 5.9x10^13 / 9.46x10^12 = 6.23 light years. So d is the correct answer.
Answer:
3 metres
Step-by-step explanation:
Let the width of the pathway be x
Area: (9+2x)(4+2x)
36 + 8x + 18x + 4x²
4x² + 26x + 36
Increased area is 150:
4x² + 26x + 36 = 150
4x² + 26x - 114 = 0
2x² + 13x - 57 = 0
2x² + 19x - 6x - 57 = 0
x(2x + 19) - 3(2x + 19) = 0
(x - 3)(2x + 19) = 0
x = 3, x = -19/2
The answer is D) 4, y = −2, z = 3
Answer:
D) Of the 4 people who have a sister, 1 of them also has a brother.
Step-by-step explanation:
P(B/A) indicates the probability of event B when event A has alredy occured.
Event A = The person has a sister.
Event B = The person has a brother.
So now P(B/A) means the probability of the person having sister who already have brother.
Hence choice "D) Of the 4 people who have a sister, 1 of them also has a brother." is correct.
Answer:
y= 10x+ 43
Step-by-step explanation:
step 1. y= 5(x+4)2+3
y= 10(x+4)
