Mavin had 4 books to read for homework this week. if he reads 2/3mof a book each night , how many nights will it take him to read all four books

6 nights

Step-by-step explanation:

Because it takes one night for Mavin to finish 2/3 of a book, you can create a ratio of book:night.

2/3:1

4:x

Then we solve for x.

x=4x * 1/ 2/3

x = 4 * 3/2

x = 6

So it will take Mavin 6 nights to finish his 4 books :)

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

step-by-step explanation:

i googled it and this is what i got i don't know how it is. sorry.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
