1 is 60. 2 is 60. 3 is 24. 4 is 365.25. 5 Is 186282. 6 is 5879000000000 or 5.879 X 10^12.
Answer:
Both of your answers are correct.
Step-by-step explanation:
Expand the equations by distributing the number outside of the parentheses. After doing the expansion, your equations are both correct.
The initial velocity is -150m/s.
Remember that:
V(t) = Vi + at, where v(t) is velocity at time t, Vi is initial velocity, and a is acceleration.
We know that the vehicle stopped after 30 seconds, so V(30) = 0.
Let's plug the useful info into our function and solve for a:
0 = -150 + a*30 Add 150 to both sides
150 = 30a Divide both sides by 30
a = 5 m/s²
The average acceleration is 5 meters per second squared.
Answer:
Consecutive sides must be congruent.
All interior angle adds up to 360°
Step-by-step explanation:
Rhombus:
1. Sides: all 4 sides are congruent.
Then consecutive sides must be congruent.
2.Diagonals : Diagonals bisect each other at 90°.
So, second option is wrong.
3. Sum of interior angle is 360°.
<span>The sum of Kate age and her mother's age is 52, so
K + M = 52
Kate's mother is 20 years older then Kate, so
M = 20 + K
How old is each person?
Since M = 20 + K, substitute it into the first equation, that is, replace M with 20 + K
So, K + (20 + K) = 52
K + 20 + K = 52
2K + 20 = 52
Subtract 20 from both sides:
2K = 52 - 20
2K = 32
divide both sides by 2 to get
K = 16
Now we can find M, since M = 20 + K = 20 + 16 = 36
Kate is 16 years old and her mother is 36 years old.
Hope this helps!!1</span>
