Answer:
The initial speed of a car at a red light would be 0 m/s, because it has fully been put to a stop. It's not moving.
Step-by-step explanation:
If a car were to fully stop there would be no speed.
For example, if you were to go walking in the city, and you were about to walk onto the crosswalk, but the signal turn into a reg light. Then you would have stopped. Then you have gone into an idle position. When in this idle position, it is like you aren't moving, so there is no acceleration in speed or decrease. It is also much like a stop sign, you would make a full stop when you see it.
Answer:
There are 14 4-point questions and 26 2-point questions.
Step-by-step explanation:
m = number of 4-point questions
n = number of 2-point questions
m+n =40
4m + 2n =108
You can solve system by elimination:
Multiply the 1st equation by -4 and keep the 2nd equation the same.
−4(m+n=40) → -4m -4n= -160
4m+2n=108 add them up
-2n = -52 divide both sides by -2
n = 26
plug it back in to solve for m
m + n = 40 →m + 26 =40 subtract 26 to both sides
m = 14
Well, you can basically do $56.88 - $41.57. After that you should get 15.31. Which is basically the same number as 15.?1 just you filled the ? in. So, now we know that Rosa is incorrect. You can check it by doing what I just showed you, 56.88 - 41.57. So now you have the info you need to write your response.
hope this helped!
Answer:
180-130 = 50 degrees because its same side angle
m<2 = 50
Step-by-step explanation:
the second one m<1 is 105 for the same reason
Answer:
Is a right triangle
Step-by-step explanation:
step 1
Find the measure of angle C
Remember that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
substitute the given values
therefore
The triangle is a right triangle, because has a internal angle of 90 degrees
