Mike had 180 blue and red pencils. he had 45 blue pencils. what percentage of his pencils was red? show work

75%

Step-by-step explanation:

There are 180 total pencils

There are 45 blue pencils

How many red pencils

180-45 = 135 red pencils

The percentage of pencils that are red = red/total

                                                                 = 135/180

                                                                 =.75

Changing to percent form

                                                                 =75%

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

answer: it's d
