A new outdoor recreation center is being built in Hadleyville. The perimeter of the rectangular playing field is 316 yards. The

algol13

Given :

Perimeter of rectangular filed , P = 316 yards.

The length of the field is 4 yards less than twice its width.

To Find :

The dimensions of the playing field.

Solution :

Let, width be x.

So, by given condition length will be 2x - 4.

Perimeter is given by :

P = 2( l + b )

316 = 2( 2x - 4 + x )

3x - 4 = 158

x = 54 yards.

So, the dimensions are 54 yards and 104.

Hence, this is the required solution.

Solve this equation: 110 = 9x + 5y Help please!!!❤️

Archy [21]

We can't find explicit values for $x$ and $y$ , since there is only one equation, but two variables.

The best we can do is solve for one variable with respect to the other:

Solve for $x$ :

subtract $5y$ from both sides:

$110-5y = 9x$

divide both sides by $9$ :

$\frac{110-5y}{9} = x$

Solve for $y$ :

subtract $9x$ from both sides:

$110-9x = 5y$

divide both sides by $5$ :

$\frac{110-9x}{5} = y$

A student's course grade is based on one midterm that counts as 20% of his final grade, one class project that counts as 20%

Rus_ich [418]

Answer:

His overall final score is 80.1.

His letter grade is a B.

Step-by-step explanation:

To find his grade, we multiply each grade by it's weight.

Grades and weights:

His midterm score is 64. The midterm counts 20% = 0.2.

His project score is 80. The project score counts 20% = 0.2.

His homework score is 94. The homework score counts 30%.

His final exam score is 77. It counts 30%.

What is his overall final score?

64*0.2 + 80*0.2 + 94*0.3 + 77*0.3 = 80.1

His overall final score is 80.1.

What letter grade did he earn (A, B, C, D, or F)?

At least 80 but less than 90 is a B. He scored 80.1, so his letter grade is a B.
