This is very easy just alot of terrible numbers lol.
If she goes "down" for 90 SEC that means she is moving Negative.
So she moves for 90 seconds at a Rate of 3.5 Feet per second
Which means every second she goes down she will subtract 3.5 Ft
Since she is moving for 90 SEC then this will be the equation
Feet will be negative because she is going down.
-3.5 X 90=? You might need a calculator.
Now that she has gone down she decided to go up. For 30 seconds at a different rate. 2.2 Seconds. So now since she is going up it is Increasing.
Feet will be Positive because she is going up now.
This is the equation
2.2 X 30=?
First you want to add both the equations you solved so far.
Now she wants to go to Exactly 0 . So she decides to go up really fast!
So when you get the amount. She wants to Increase by 4.8 FT Per SEC
So you take the amount you added which should be negative
And put it into an equation.
4.8 Divided by ( the equation you added) = ? SEC
SEC= SECONDS FT= FEET
Answer:
4n (3n - m)
Step-by-step explanation:
See what they both have, pull it to the outside, put what is left inside.
4n (3n - m)
24 times 2 equals 48 , 24 times 3 equals 72 . Therefore it’s A
Answer:
a = 127°
Step-by-step explanation:
The 3 angles lie on a straight line and have a sum of 180°, that is
15° + a + 38° = 180°
53° + a = 180° ( subtract 53° from both sides )
a = 127°
