Answer: 166 2/3m

Step-by-step explanation:

Area of a rectangle = length times width

Length: 16 2/3

To find the width, multiply it by 3/5.

w = 16 2/3 · 3/5

w = 10

Then, multiply the length by the width.

a = l · w

a = 16 2/3 · 10

a = 166 2/3m

For the final days before the election, the campaign manager has a total of $41,500 to spend on TV and radio campaign advertisem

Margaret [11]

Answer: There are 9 T.V. and 29 radio ads.

Step-by-step explanation:

Since we have given that

Total amount spend on TV and radio = $41,500

Total number of voters using the allocated funds = 148,000

Let the number of TV be 'x'.

Let the number of radio ads be 'y'.

Cost of each TV = $3000

Cost of each radio ads = $500

Number of voters see T.V. = 10,000

Number of voters use radio = 2000

So, According to question, it becomes,

$3000x+500y=\$41500\implies\ 30x+5y=415\\\\10000x+2000y=148000\implies 10x+2y=148$

Using the graphing method, we get that

These two lines are intersect at (9,29).

Hence, there are 9 T.V. and 29 radio ads.

Haruka owns an umbrella factory. The revenue,R, she makes from selling n umbrellas is given by the function R(n)=18n, and the pr

RSB [31]

The question is to find an expression for the expenses

Answer:

E (x) =n + 5

Explanation:

The profit is defined as the difference between the revenue and the expenses.

This means that:

profit = revenue - expenses

Now, we rearrange the equation to solve for expenses:

expenses = revenue - profit

From the given, we know that:

expression for revenue is 18n

expression for profit is 17n - 5

Substitute in the equation to get expression for expenses as follows:

E (x) = 18n - (17n - 5)

E (x) = 18n - 17n + 5

E (x) = n + 5

Hope this helps :)
