Rate of change =
So grab 2 Y's first and then subtract
7 - 3 = 4
and do the same for X
4 - 2 = 2
Simplify
4/2 = 2
2 is your rate of change
First, find out how many messages are received a second. Do this by dividing messages by 60 seconds.
120/60 = 2 messages a second
now multiply 2 by 150
2*150 = 300messages in 150 seconds
your answer is (3) 300
27 miles per hour
1 hour = 60 minutes
27 miles per 60 minutes
27/60 miles per 1 minute
9/20 miles per minute
I don’t know how you think this is a opinion
we know that
if ∠UVW and ∠XYZ are complementary angles
then
∠UVW + ∠XYZ=90°
∠UVW=x-10
∠XYZ=4x-10
substitute the values
(x-10)°+(4x-10)°=90°
Solve for x
5x-20=90
5x=90+20
5x=110
x=22°
∠UVW=x-10=22-10=12°
∠XYZ=4x-10=4*22-10=78°
therefore
<u>the answer is</u>
x=22°
∠UVW=12°
∠XYZ=78°
