Answer:

You can use distributed property and GCF to find an equivalent expression because the GCF of both numbers is in the expression the GCF is what you multiply with to get the first whole number then the second (63 and 81) the GCF of 63 and 81 is 9. That gives us a clue for the expression or the first factor. You can check if you are correct by evaluating the expression and if your expression has an equivalent product to 63+81 then you are correct.

Step-by-step explanation:

I got it right on edgenuity the answer above me is incorrect I tried it.

Ab+ac=a(b+c)
find a which is the GCF

63=3*3*7
81=3*3*3*3
GCF=3*3=9

9(7)+9(9)=9(7+9) is an equivilent expression
you can check by evaluating

Random sampling is similar to placing the name of everyone in a hat and pulling out a few names.

Convenience sampling: data which is readily available is used. That is, the first people are running into by the surveyor.

In Cluster sampling, we divide the population into groups, usually geographically.

Here the population is divided into groups of males and females therefore it is stratified sampling.

Hence, the type of sample is Stratified sampling.

A boat traveled 128 kilometers in

AlekseyPX

Answer:

The Distance cover by boat in 2 hours and 15 minutes is 72 km

Step-by-step explanation:

Given as :

The Distance cover by boat = 128 kilometer

The time taken is 4 hours

As , Distance = Speed ×Time

So , Speed = $\frac{Diastance}{Time}$

Or, Speed = $\frac{128 km}{4 hours}$

∴ Speed = 32 km per hour

Now, again The boat travel 2 hours and 15 minutes further with speed 32 kmph

So, Time2 = 2 + $\frac{15}{60}$

Or, Time2 = 2 + $\frac{1}{4}$

I.e Time2 = $\frac{9}{4}$ hours

Again , Distance = Speed ×Time

So , Distance = 32kmph × $\frac{9}{4}$ hours

I.e Distance = $(\frac{32\times 9}{4})$ = 72 kilometer

Hence The Distance cover by boat in 2 hours and 15 minutes is 72 km Answer
