Answer:

x = 4.8 , y = 4

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{KJ}{NP} = \frac{KL}{NM} , substitute values

\frac{x}{3} = \frac{8}{5} ( cross- multiply )

5x = 24 ( divide both sides by 5 )

x = 4.8

and

\frac{JL}{PM} = \frac{KL}{NM} , that is

\frac{6.4}{y} = \frac{8}{5} ( cross- multiply )

8y = 32 ( divide both sides by 8 )

y = 4

Step-by-step explanation:

-let x denote the number of standard version downloads.

-Given that the high-quality version was downloaded four times as often as the standard version it is denoted as 4x

-This can then be expressed as:

x(2.9)+4x(4.8)=6188\\\\2.9x+19.2x=6188\\\\22.10x=6188\\\\x=280

Hence, the number of standard version downloads is 280

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.
