Rodrigo took a math quiz last week. He got 63 problems correct and 7 problems incorrect. What percentage did Rodrigo get correct? Write your answer using a percent sign (%).

Step-by-step explanation:

so, there were in total 63 + 7 = 70 questions.

therefore,

100% = 70

1% = 100%/100 = 70/100 = 0.7

to know how many % are the 63 correct answers we need to divide 63 by 1% :

63 / 0.7 = 90%

so, he got 90% correct.

58.59

Step-by-step explanation:                                                                                           Here we will explain how to calculate the answer to: 63 minus 7 percent. To find the answer, we first calculate what 7 percent of 63 is, and then we deduct that amount from 63 to get the answer.

To get the 7 percent from any number such as 63, we multiply the number by 7 and then divide that answer by 100. Thus, to find 7 percent of 63, we do this:

(63 x 7)/100 = 4.41

Next, we simply subtract 4.41 from 63 like this:

63 - 4.41 = 58.59.

Therefore, as illustrated and calculated above, the answer to "What is 63 minus 7 percent?" is as follows:

explanation:

step-by-step explanation:

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
