Step-by-step explanation:
sinx=20/36
x=sin-¹20/36
x=34
Lets x = Mary's age
Emily is there years older than twice her sister Mary's age = 2x + 3
Sum of both is less than 30:
x + 2x + 3 < 30
Solve for x
3x + 3 < 30
3x < 27
x < 9
Mary's age = 9
Inequality represents Mary's possible age:
0 < x < 9
Answer is the second one
0 < x < 9
You would need to multiply 35 x .6 (which is 60%).
35 x .6 = 21, so at least 21 members need to be present to vote.
Answer:
(1.1 , 0.6)
Step-by-step explanation:
midpoint (x , y): ( x+x') /2 , (y+y') / 2
x = (-3.5 + 5.7) / 2 = 2.2 / 2 = 1.1
y = (-2.1 + 3.3) / 2 = 1.2 / 2 = 0.6
Answer:
1 to 5
211 to 1500
11 to 300
Step-by-step explanation:
1.8 to 9 = 18/90 = 1(18)/5(18) = 1/5 = 1 to 5
2.11 to 15 = 211/1500 = 211 to 1500
3.30 to 90 = 330/9000 = 110/3000 = 11/300 = 11 to 300
