lilavasa [31]3 years ago
4 0

Answer:

a=45 b=65

Step-by-step explanation:

You know that all the angle measures of a triangle add to 180. So the equation would be angle a + angle b + 70 = 180. Subsitute and simplify and you get 16x -2 + 70 = 180. Subtract 70 from 180 to get 16x -2=110 add 2 to get 16x =110. Divide each side by 16 to gte x=7. Subsitute x = 7 into the equations for angle a and angle b to get the answers above

Joe can choose between a monthly salary of $1,800 plus 6.5% of sales or $2,100 plus 4% of sales. He expects sales between $5,000
Lapatulllka [165]

Answer:

<h2>Joe should choose $2100 + 4% of Sales</h2>

Step-by-step explanation:

       The options available to Joe are ($1800 + 6.5% of sales) and ($2100 + 4% of sales) for his salary. He chooses the option in which he would get higher salary. Sales are expected to lie between $5000 and $10000.

       Let the sales be denoted by x (in Dollars). Joe chooses first option if it is a higher number than the second.

    ⇒ if 1800+\frac{6.5}{100}x>2100+\frac{4}{100}x

        \frac{2.5}{100}x>300\\x>12000

       So, he chooses first option if x(=Sales)>12000. However sales is between $5000 and $10000. So, Joe will go with second option.

∴ Joe should choose $2100 + 4% of sales.

A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the
slamgirl [31]

Answer:

The maximum profit is 5070 dollars

Step-by-step explanation:

The profit y is represented by a quadratic function.

The equation that we can use to find a maximum value of a quadratic function is:

Max_value = c - (b^2 / 4a)

Where a, b and c are the coefficients of the quadratic function (in our case: a = -13, b = 770, c = -6332)

So, using this equation, we have:

Max_value = -6332 - (770^2 / 4*(-13)) = -6332 - 592900/(-52)

Max_value = -6332 + 11401.92 = 5069.92

rounding to the nearest dollar, we have that the maximum profit is 5070 dollars.
