{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: - 5 {x}^{2} (4x - 6 {x}^{2}  - 3)

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \:( - 5x {}^{2}  \times 4x) - ( - 5 {x}^{2}  \times 6 {x}^{2} ) - ( - 5 {x}^{2}  \times  3)

{ \qquad{ \sf{ \dashrightarrow}}}  \:  \: \sf \: - 20 {x}^{3}    - ( - 30 {x}^{4} ) - ( - 15 {x}^{2} )

Ganezh [65]
If 32 is divided by 6, the answer is 5.3. However because she cannot hit part of a ball, the number would be 5. Therefore, she would hit 5 out of 32 balls.

After taking 7 quizzes, your average is 77 out of 100. What must your average score be on the next five quizzes to increase your
Anna [14]

Answer:

89.

Step-by-step explanation:

We have been given that after taking 7 quizzes, your average is 77 out of 100. We are asked to find what average score be on the next five quizzes to increase your average to 82.

The total of 12 quizzes to get 82 would be 12\times 82=984.

The total scores earned by you in previous 7 quizzes are 7\times 77=539

The total scores you need to earn on next 5 quizzes would be difference of scores in 12 quizzes and total scores in 7 quizzes as:

984-539=445

Now, we will divide total scores on coming 5 quizzes by 5 to find the average as:

\text{Average score on next 5 quizzes}=\frac{445}{5}

\text{Average score on next 5 quizzes}=89

Therefore, your average score on the next five quizzes should be 89 to increase your average to 82.
