Answer:
135°
Step-by-step explanation:
In order to answer the question, we must assume that the black lines are parallel to each other.
The given angles (2, 8) are "same-side (consecutive) exterior" angles, so are supplementary.
∠2 +∠8 = 180°
15x +5x = 180°
x = 180°/20 = 9°
∠2 = 15x = 15(9°) = 135°
Angles 2 and 3 are vertical angles, so angle 3 has the same measure as angle 2.
∠3 = 135°

- Aidan buys used bicycles, fixes them up, and sells them. His average cost to buy and fix each bicycle is $27. He also incurred a one- time cost of $960 to purchase tools and a small shed to use as his workshop. He sells bikes for $67 each. How many bicycles does Aiden have to sell to reach the "break-even" point?
Answers
Answer: Adrian will need to fix 25 bikes to reach a break even point.
The number of bicycles does have to sell to reach the "break-even" point'' will be 24.
What is a break-even point?In economics, business, and particularly cost accounting, the break-even point is the point at which total cost and total income are equal, or "even." No net gain or loss has occurred, and one has "broken even,".
Given that Aidan buys used bicycles, fixes them up, and sells them. His average cost to buy and fix each bicycle is $27. He also incurred a one-time cost of $960 to purchase tools and a small shed to use as his workshop. He sells bikes for $67 each.
The number of bicycles will be calculated as:-
27 = ( 67n - 960 ) / n
27n = 67n - 960
40n = 960
n = 960 / 40
n = 24
Therefore, the number of bicycles does have to sell to reach the "break-even" point'' will be 24.

A number cube was designed to land on the number 6 more frequently than a standard number cube. What could be the probability of rolling a 6 with this number cube?
A. 1/4
B. 1/8
C. 1/12
D. 1/6
Answers
Answer:
Step-by-step explanation:
Standard cube rolling a 6 has a 1/6 probability or 0.1667
if a cube was designed (ie weighted) to come up more often the probability of rolling a 6 would be HIGHER than the standard cube
Which of the four given answers has a HIGHER probaility value?
1/4 0.25 > 0.1667
1/8 0.125 < 0.1667
1/12 0.0833 < 0.1667
1/6 0.1667 = 0.1667
Which answer is greater than 0.01667?

Newton's Law of Cooling states that the rate of change of the temperature of an object, T, is proportional to the difference of T and the temperature of the region, TR or dT over dt equals k times the quantity T minus T sub R end quantity. An object with core temperature of 1200°F is removed from a fire and placed in a region with a constant temperature of 80°F. After 1 hour, its core temperature is 830°F. What is the object's core temperature 4 hours after it is taken off the fire?
Answers
Answer:
- 278.4°F
Step-by-step explanation:
Temperature of Object ( T ) = 1200° F
Temperature of surrounding ( M ) = 80°F
Time ( t ) = 1 hour
dT / dt ∝ ( M - T )
dT /dt ∝ | ( 80 - 1200 ) |
dT / dt = k ( 1120 )
(1200 - 830 ) / 1 = k ( 1120 )
hence k = ( 1200 - 830 ) / 1120
= 370 / 1120 = 0.33
what is the object's temperature (x )after 4 hours
( 1200 - x ) / 4 = 0.33 ( 1120 )
( 1200 - x ) / 4 = 369.6
hence x = 1200 - ( 4 * 369.6 )
= - 278.4 ° F
