Answer:

m<BGC = 145°

Step-by-step explanation:

<AGC and <DGB are vertical angles. Vertical angles are congruent. Therefore:

m<AGC = m<DGB

[tex] 3x + 20 = 8x - 5 [/tex] (substitution)

Collect like terms

[tex] 3x - 8x = -20 - 5 [/tex]

[tex] -5x = -25 [/tex]

Divide both sides by -5

x = 5

m<BGC = 180 - (m<AGC) (linear pair)

m<BGC = 180 - (3x + 20)

Plug in the value of x

m<BGC = 180 - (3(5) + 20) = 180 - 35

m<BGC = 145°

10. An electric scooter manufacturer estimates that the cost C in dollars) of producing x
scooters is given by C(x) = 600+ 0.05x + 0.0002x%. Find the production level, to the nearest
unit, that will minimize the average cost Č(x) per unit.
A. 1733 scooters
B.
1250 scooters
C. 600 scooters
D.
1500 scooters

Answers

Answer:

A. 1733 scooters

Step-by-step explanation:

To get x for minimum value of C bar, set derivative = 0

We Find our x.

C(x) = 600+ 0.05x + 0.0002x^2

We need average cos per unit

So divide by x both sides

C(x) / x = 600/x + 0.05x + 0.0002x

c(x)/c = Ç(x)

Therefore, Ç(x) = 600/x + 0.05x + 0.0002x

Now differentiate both side with x

dÇ(x)/dx = 600/x^2 + 0 + 0.0002

To find x for minimum Ç(x)

Set dÇ(x)/dx = 0 => -600/x^2 + 0.0002 = 0

=> x^2 = 600/0.0002

x^2 =3000000

x = √3000000

x = 1732.05

x = 1733

You were billed $28.50 for additional data usage on your cell phone at a rate of $9 per gigabyte. Three choices are correct ways to calculate the additional gigabytes, g, that you used. Which choice is NOT?

Answers

Answer:

b.) 9/g = 28.5

Step-by-step explanation:

a.) 9g = 28.5

b.) 9/g = 28.5

c.) 28.5 = 9 x g

d.) 28.5/9 = g

Total billing = $28.50

Rate = $9 per gigabyte

Calculate the additional gigabytes, g, that you used.

Additional gigabyte used, g = Total billing / Rate

g = $28.50 / $9

9g = 28.50

28.50 = 9 × g

g = 28.50 / 9

Option b.) 9/g = 28.5 is the incorrect way to calculate the additional gigabytes, g, that you used.
