Eliminate y by writing the bottom equation into the top one:
-1/2x - 4 - 3x = 3
-3.5x = 7
x = -2
y= -1/2 * -2 - 4 = -3
Answer:
1/12
Step-by-step explanation:
to get a odd number is a 1/2 chance. to roll a 3 is a 1/6 chance. multiply those together to get 1/12.
1) You know the height of the bird from the observer is the same as the height of the plane to tower. We also know that the angle of depression is same as the angle of elevation.
So we will use the tangent function to find the value of x.
tan 23 = 5000 / x
x = 5000 / tan 23
x = 11779
You're answer will be 11779 feet
2) We will use the sine function.
sin 35 = 17,000 / x
x = 17,000 / sin 35
x = 29638.6
So the answer would be approximately 29639
Answer:
1 13/24 liters
Step-by-step explanation:
To find the answer we have to subtract the liters of water in the bucket from the liters of water in the pail.
3 3/8 - 1 5/6
27/8 - 11/6
change the denominator
3x27/24 - 4x11/24
81/24-44/24
37/24
convert into a mixed number
1 13/24 liters
