Can someone explain to me how to find if an Algebra Expression is Equivalent to another

First of all, you need to simplify the expressions in order to know whether they are equal. Then, it all depends on the expression, after you simplify an expression, it will seem much easier to determine that.

A university professor asked his class of 42 students when they had studied for his class the previous weekend. There responses

Basile [38]

ANSWERS:

a) 16 students

b) 25 students

c) 2 students

STEP BY STEP:

There are 42 students in total. This question can be solved by "Principal of Inclusion and Exclusion"

Question a)

The students that studied on Sunday in total with overlaps is 30. To figure out the students that ONLY studied on Sunday you need to first minus the overlaps in the combos:

the combos:

3, 10, 6, 2

Since the last combo included all of the other dates, we need to minus it:

1, 8, 4, 2

Now we can use the total of Sunday and minus the combos that includes Sunday:

30 - (4 + 2 + 8) = 16 students

Question b)

To figure out all the students that only studied on ONE day, not 2 not 3, just one day. We need to figure out the students that studied for Saturday and Friday using the same method before for figuring out Sunday:

Friday: 9 - 4 - 1 -2 = 2 students

Saturday: 18 - 1 - 2- 8 = 7 students

and now add them all together: 2 + 7 + 16 = 25 students

That is the total number of students that studied on one day.

Question c)

Now for the numbers of students that didn't study... We can just use the total to minus everything else!

42 - (25 + 1 + 4 + 8 + 2) = 2 students!!!

And thats all done! If you still don't get it, please ask!

Please help with this question?!?

Answer:

416 mi

Step-by-step explanation:

In order to find the surface area, you must find the area of each square. There are a total of 6 that make up the prism.

Remember to find the area it is length x width

9 x 8 = 72 which is the area for 4 of the squares. 2 on the side and 2 on the bottom
Lastly for the last 2 squares to find the area you multiply 8 x 8 = 64
In total, you will add 72+72+72+72+64+64 which equals 416

if A+n=180

75+90+n=180

165+n=180

n=180-165

n=15

A+n=180

A+15=180

A=180-15

A=165 (D)

Rewrite the radical as a rational exponent. the fourth root of 7 to the fifth power 7 to the 5 over 4 power 720 7 7 to the 4 ove

adoni [48]

I don't understand what you mean by "720 7 7 to the 4 over 5 power", but for "the fourth root of 7 to the fifth power 7 to the 5 over 4 power" it would be 7^5 (seven to the power of 5)
