Answer:
1) 28m West 2)70km below sea level
Answer:
X=1 and Y=5
Step-by-step explanation:
X Y-X/Y=5.....(1)
XY-Y/X=1/5....(2)
subtract(2) from 1 you have
Y/X-X/Y=5-1/5
Y/X-X/Y=5/1-1/5
so, by equating LHS and RHS
X=1 and Y=5
3/2 is the same 15/10 so the answer. there are 3 boys to every 2 girls 9/6 the answer. 9 boys and 6 girls
Answer:
Option A
Step-by-step explanation:
Consider the Fibonacci series:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...
Ignore the first 3 terms ( keys)
f(5)/f(4) = 5/3 = ~1.67
f(6)/f(5) = 8/5 = 1.60
f(7)/(f6) = 13/8 = ~1.63
f(8)/f(7) = 21/13 = ~1.61
f(9)/f(8) = 34/21 = ~1.62
f(10)/f(9) = 55/34 = ~1.62
...
=> Option A is the solution
Answer:
‹A = 141°
‹B = 28°
‹C = 11°
*These angles are rounded to the nearest whole*
Step-by-step explanation:
Because you are only given sides you can find an individual angle measures with the inverse law of cosines.
Remember the side opposite of the angle corresponds to that angle.
a² = b² + c² - 2bc cos(A) →
A = cos⁻¹ (a² - b² - c² / -2bc)
b² = a² + c² - 2ac cos(B) →
B = cos⁻¹ (b² - a² - c² / -2ac)
c² = a² + b² - 2ab cos(C) →
C = cos⁻¹ (c² - a² - b² / -2ab)
