Bill has $10 coupon for the party store. He needs to buy 25 balloons for a birthday party. If each balloon costs $1.99, and Bill

natita [175]

The total cost of his purchase is $9.95

Bill has a $10 coupon

He needs to buy 25 balloons

Each balloons cost $1.99

The first step is to divide the coupon amount which is $10 by the cost of the balloon which is $1.99

10/1.99

= 5

The next step is to multiply 5 by the cost of the balloon which is $1.99

5× 1.99

= 9.95

Hence the total cost of his purchase is $9.95

I need help with Estimated Variable and Fixed Cost. How do I figure that out in the problem attached?

saul85 [17]

The fixed and variable costs of the given table of production costs are respectively; $161280 and $42

<h3>How to calculate fixed and variable costs?</h3>

Variable costs are costs that vary/change depending on the company’s volume of production while fixed costs are costs that do not change in relation to volume of production.

Fixed costs = Production Cost + Selling expenses + Administrative Expenses

Fixed Cost = $103200 + $21500 + $7300 + $1600 + $1800 + $21000 + $2600 + $2280 = $161280

Variable cost = $15 + $10 + $8 + $3 + $3 + $1 + $2

Variable cost = $42

I NEED HELP!!!!!!!!!!!!!!!!

antoniya [11.8K]

Step-by-step explanation:

just think back to the standard circle of radius = 1.

there the trigonometric functions are all represented as sides of right-angled triangles, where the radius is the baseline.

just like the triangle we are seeing here.

the only difference : the baseline (radius) is 17 and not 1.

and that is fine. everything is as in the standard circle, but multiplied by the radius (which is also true for the standard circle, but multiplying by 1 does not change anything, right ?).

a)

angle A is or focus. so, just imagine the triangle turned counterclockwise by 90° (so that AC is horizontal and CB is vertical).

do you see it now ?

sin is the vertical leg, cos the horizontal leg. and the leg lengths here are the standard functions multiplied by the radius.

so,

17 × sin A = 8

sin A = 8/17 = 0.470588235... ≈ 0.47

b)

17 × cos A = 15

cos A = 15/17 = 0.882352941... ≈ 0.88

c)

now B is our focus. imagine the triangle being mirrored at point B, so that B is left, and AC is right. your see it now ?

tan B = sin B / cos B

sin B = 15/17 = 0.882352941... ≈ 0.88

cos B = 8/17 = 0.470588235... ≈ 0.47

tan B = 15/17 / 8/17 = 15/8 = 1.875 ≈ 1.88

d)

cos B = 8/17 = 0.470588235... ≈ 0.47

Answer:

Charlie is incoerre

Step-by-step explanation:

Given that :

Line of sight to top of flagpole = 16 feets

Angle of elevation = 60°

The height of the flagpole :

Applying trigonometry to the drawing in the attached picture :

We use:

Sinα = opposite / hypotenus

This enables us to use the value of the hypotenus (line of sight) to obtain the missing height value (h)

Sin(60°) = h / 16

h = 16 * sin 60

h = 16 * 0.8660254

h = 13.856406

Hence flagpole is about 13.86 feets high

Charlie's reasoning is incorrect, the line of sight constitutes the hypotenus and not Adjacent and hence, shoul
