Nicole usually scores between 89%

Mathematics
1 answer:
Mnenie [13.5K]3 years ago
6 0

Answer:

B

Step-by-step explanation:

Nicole usually scores between 89% and 100% on her math quizzes.

On the quizzes she takes right after a track meet, she has about an 11% decrease in her score, so she will earn 100% - 11%  = 89% of her usual score.

1. 89% of 89% is

0.89\cdot 89\%=79.21\%\approx 79\%

2. 89% of 100% is

0.89\cdot 100\%=89\%

So, if Nicole had a track meet the day before a quiz, her score would be between 79% and 89%.

(4x-5)+2(3x+1)<br> Can you help me solve this plz for me
Korvikt [17]

Answer:

10x - 3

Step-by-step explanation:

First, distribute 2 to all terms within the second parenthesis:

2(3x + 1) = (2 * 3x) + (2 * 1) = 6x + 2

4x - 5 + 6x + 2

Combine like terms (terms with the same amount of variables).

4x + 6x + 2 - 5

(4x + 6x) + (2 - 5)

10x + (-3)

10x - 3

10x - 3 is your answer.

The price of an airline ticket was $320 amd it is now 420$ what is the percent increase the price of the ticket
enyata [817]

Answer:

 31.25 percent increase

Step-by-step explanation:

To find the percent increase, we take

percent increase = (new - original)/new * 100 percent

                            = (420-320)/320 * 100 percent

                              100/320 * 100 percent

                              .3125 * 100 percent

                               31.25 percent increase

The answer with an explanation please
ValentinkaMS [17]

Answer:

5C

6C

7D

8B

Step-by-step explanation:

5) C because median is the middle of the set of numbers source A median is 4 source B median is 6 and 4 is 2 less than 6.

6) C  because there are  6 numbers altogether and 1 6s on a dice so 6+6 because we have two dice and 2 6s on both so 2/12 or simplified 1/6

7) D because mean is all the numbers add up divided by the amount of numbers so 20+25+30+20+30 = 125 and 125 ÷ 5 = 25

8 B because mean is all the numbers add up divided by the amount of numbers so

5+6+7+8+8+8+8+8+8+9+9 = 76 ÷ by 10 is 7.6

7+7+7+7+8+8+8+8+10+10 = 80 ÷ by 10 = 8

8 + 7.6 = 15.6 ÷ 2 = 7.8 and B is closest to 7.8
