To get on the top players list , don needs to have a minimum average score of 225 after playing four games. His scores on his fi
Black_prince [1.1K]
Average must be 225 or more
4 games so
\frac{score1+score2+score3+score4}{4}  \geq 225
score1=192
score2=214
score3=250
score4=?
so
\frac{192+214+250+?}{4}  \geq 225
\frac{656+?}{4}  \geq 225
times both sides by 4 to clear fraction
656+?≥900
minus 656 from both sides
?≥244

min score is 244

sesenic [268]

The value of the given expression (3m - n)² + 4m when m = 63 and n = 45 is equal to 20,916.

<h3>What is an expression?</h3>

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

<u>Given the following variables:</u>

  • m = 63.
  • n = 45.

Substituting the given variables into the given expression, we have;

Expression = (3m - n)² + 4m.

Expression = (3(63) - 45)² + 4(45).

Expression = (189 - 45)² + 180

Expression = 144² + 180

Expression = 20,736 + 180

Expression = 20,916.

Radha purchased a cosmetic item at 5 % discount. If she got the discount amount of
Fiesta28 [93]

Answer:

She purchased the item at a price of Rs 1,406.

Step-by-step explanation:

5% of discount:

This means that she paid 100% - 5% = 95% = 0.95 of the original price of x, that is, 0.95x, and 0.05x was the discount.

Original price:

She got the discount amount of Rs 74.

74 is 5% of the original price, that is:

0.05x = 74

x = \frac{74}{0.05}

x = 1480

What price she purchased:

74 subtracted from the original price, that is, x - 74. So 1480 - 74 = 1406.

She purchased the item at a price of Rs 1,406.
