Davinci Digital Media’s wholesale price to the retailer for a digital video camcorder is $1,399.99. Manufacturing costs include $360.00 for production wages and benefits. Production wages and benefits are what percent of the wholesale price to the retailer?

Answers

If you would like to know what percent of the wholesale price to the retailer are production wages and benefits, you can calculate this using the following steps:

x% of $1,399.99 is $360.00
x% * 1,399.99 = 360.00
x/100 * 1,399.99 = 360.00
x = 360.00 * 100 / 1,399.99
x = 25.71%

The correct result would be 25.71%.

An angle measures 142° less than the measure of its supplementary angle. What is the measure of each angle?

Answers

Answer:

19° and 161°

Step-by-step explanation:

A - an angle

S - its suplementary angle

A = S - 142°

Suplementary angles add to 180° so:

A + S = 180°

S - 142° + S = 180°

2S = 322°

S = 161°

A = 161° - 142° = 19°

What is the equation of -1/2 that passes through the point (6,-6) Options are ..1) y= 1/2x-3
2) y= -1/2x+3
3) y= -1/2x-3
4) y= -2x-3

Please explain why the answer is what it is.

Answers

formula of the line is
y = mx + c
we know y, m and x, find c

-6 = $- (1)/(2)$ (6) + c
-6 = -3 + c
-6 + 3 = -3 + 3 + c
-3 = c

y = $- (1)/(2) x$ - 3

Last year a large trucking company delivered 9.0 x 105 tons of goods with an average value of $17,000 per ton. What was the total value of the goods delivered? Write the answer in scientific notation

Answers

So, we have 9×105 tons of goods. Which gives us a total of 945 tons.

These goods have the average value of 17000 per ton. When we turn that into an equation we got: $945 * 17000 = 16065000$

When we convert that into scientific notation, we can write that as: $1.6065 * {10}^(7)$
