Irina-Kira [14]2 years ago
5 0

Answer:

130°

Step-by-step explanation:

e =  \frac{1}{2} (100 \degree - 80 \degree) \\  \\ e =  \frac{1}{2}  \times 20 \degree \\  \\ e = 10 \degree \\  \\ a =  \frac{1}{2}  \times 80 \degree \\  \\ a = 40 \degree \\  \\ by \: interior \:  \angle \: sum \: postulate \: of \: a \:  \triangle \\ a + e + f = 180\degree \\40\degree + 10\degree + f = 180\degree \\50\degree + f = 180\degree \\f = 180\degree - 50\degree \\\huge \red {\boxed {f = 130\degree}}

Fill in the table using this function rule y=5x-3
Rudiy27

Answer:

-2, -13

0, -3

2, 7

4, 17

Step-by-step explanation:

To fill out the table, substitute the table x-values into the equation and the y-values will fill the table.

y = 5x - 3

y = 5(-2) - 3

y = -10 - 3

y = -13

This means the table value corresponding to -2 should be -13.

y = 5x - 3

y = 5(0) - 3

y = 0 - 3

y = -3

This means the table value corresponding to 0 should be -3.

y = 5x - 3

y = 5(2) - 3

y = 10 - 3

y = 7

This means the table value corresponding to 2 should be 7.

y = 5x - 3

y = 5(4) - 3

y = 20 - 3

y = 17

This means the table value corresponding to 4 should be 17.

25% of the time there is free breakfast at work. You just woke up and are really hungry, so you call your coworker who is alread
Mice21 [21]

Answer:

0.17

Step-by-step explanation:

The number of times there is free Breakfast at work = 25%

The number of times the coworker lies = 1/3

The number of times the coworker speaks truth = 2/3

How likely is it that there is free breakfast at work today:

For this to happen both conditions must be satisfied. There must be free breakfast at work AND the coworker has also spoken truth. Now in this condition we will use the AND rule of Probability where we will take the Product of both the probabilities.

Result = 0.25 x 0.67 = 0.17

Avery is in the business of manufacturing phones. She must pay a daily fixed cost to
tangare [24]

Answer:

The equation that represents the total cost in dollars is C = 100p + 300

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

  • m is the slope ⇒ rate of change
  • b is the y-intercept ⇒ fixed amount

∵ Avery must pay a daily fixed cost to  rent the building and equipment

∴ There is a fixed amount b

∵ She pays a cost per phone produced for  materials and labor

∴ There is a rate m

∵ C represents the total cost of producing p phones in dollars

→ Form the linear equation for the situation

∴ The equation is C = m p + b

∵ The labor and materials cost $100 for each phone

∴ m = 100

→ Substitute it in the equation above

∴ C = 100p + b

∵ The cost of producing 3 phones in a day would be $600

∴ p = 3 and C = 600

→ Substitute them in the equation above to find b

∵ 600 = 100(3) + b

∴ 600 = 300 + b

→ Subtract 300 from both sides to find b

∵ 600 - 300 = 300 - 300 + b

∴ 300 = b

→ Substitute it in the equation

∴ C = 100p + 300

∴ The equation that represents the total cost in dollars is C = 100p + 300
