Answer:
Step-by-step explanation:
you multily the negative by the positive and get a negative answer so -36.8
Answer: m=vD
Step-by-step explanation:
To get m alone, you want to use algebraic properties.
[multiply both sides by v]
Now that we have mass alone, we know that m=vD.
<u>Answer:</u>
Two arcs on a circle having central angle as
and
are not congruent.
<u>Solution:</u>
Need to find whether two arcs having central angle as
and
of same circle are congruent or not.
<em>For congruency of two arcs, radius and length of the arc must be same.
</em>
Since two arcs in discussion is on same circle, so radius is equal
Let’s assume radius of circle = r

where θ is central angle.
So length of the arc when central angle 
Length of the arc when central angle = 
So clearly length of the two arc are not equal. Hence two arcs having central angle as
and
are not congruent.
The model for representing the ratio of the number of orange and green rolls are 
A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms will be 3O=2G
<h3>What is ratio?</h3>
The ratio is defined as the representation of the one number with respect to the other number. or one number is how many times to the other number.
A model that represents the ratio of different coloured streamers.

A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms.
3O=2G
Hence the models are
and 3O=2G
