Solve for M<br> D=m/v<br> Show your work
luda_lava [24]

Answer: m=vD

Step-by-step explanation:

To get m alone, you want to use algebraic properties.

D=\frac{m}{v}                  [multiply both sides by v]

m=vD    

Now that we have mass alone, we know that m=vD.

In a circle if you have two arcs one is 60° and one is 97° are they congruent
Debora [2.8K]

<u>Answer:</u>

Two arcs on a circle having central angle as 60^{\circ} and 97^{\circ} are not congruent.

<u>Solution:</u>

Need to find whether two arcs having central angle as 60^{\circ} and  97^{\circ} 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

\text { Length of the arc }=2 \pi r \times\left(\frac{\theta}{360}\right)

where θ is central angle.

So length of the arc when central angle =60^{\circ}=2 \pi r \times \frac{60}{360}=0.3333 \pi r

Length of the arc when central angle = 97^{\circ}=2 \pi r \times \frac{97}{360}=0.5388 \pi r

So clearly length of the two arc  are not equal. Hence two arcs having central angle as 60^{\circ} and 97^{\circ} are not congruent.

The model for representing the ratio of the number of orange and green rolls are   \dfrac{3}{2}=\dfrac{O}{G}

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.

 \dfrac{3}{2}=\dfrac{O}{G}

A model that shows the number of orange and green streamers needed to decorate 3 dorm rooms.

 

3O=2G

Hence the models are    \dfrac{3}{2}=\dfrac{O}{G}   and     3O=2G
