There are 40 students in a class. Today only 29 students showed up. What percentage of students showed up? Show and explain your work.

72.5%

Step-by-step explanation:

29 is the number of students showed up

40 are the number of students in the class

= 29/40 × 100/100

= 29/2× 5/100 we have simplified the fraction

=(29/2× 5)/100

=( 145/2) × 100

=72.5/100

=72.5%

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
