Step-by-step explanation:
-3.25y < -61.75
<u>-3.25y</u><u> </u>< <u>-61.75</u><u> </u>
-3.25. -3.25
whenever an inequality is divided by a negative number the sign changes, so if the sign of the inequality is greater than( > ) it becomes less than( < ) or the other way around. In this case the <em>less</em><em> </em><em>than</em><em> </em>will be <em>greater</em><em> </em><em>than</em><em>.</em>
y > 19 , S.S= [ 20,21,22,23.....]
First move the numbers to the other side
x+x = 33-4-7
2x = 22
Next divided both sides by 2 to get x on its own
X=11
Therefore the answer is A
Answer:
teenagers who watch TV =2
teenagers wearing glasses =5
hence probability =2/5=0.4
now you prove how ur answer is 0.5
Answer: The tall cliff is 118.20 feet tall and the short cliff is 70.32 feet tall.
If you draw a picture with 2 cliffs and a river in the middle, you have find 2 right triangles. In each triangle the adjacent side to our known angle is the river of 90 feet. And the unknown side is the opposite leg.
Therefore, we can set up a tangent equation.
From the top of the short cliff to the top of the tall cliff, we can right and solve the following trig equation:
tan(28) = x /90
x = 47.88
From the top of the short cliff to the bottom, we can right and solve the following trip equation.
tan(38) = x/90
x = 70.32
The 70.32 is also the height of the short cliff. And adding the two answers together will give you the height of the tall cliff.
There are 1,760 yards in a mile.
Multiply 1,760 by 2 = 3,520
Add 50 to 3,520 = 3,570
Stephanie's trip was 3,570 yards long.
