A+B+C+D=360

A=180 as it half of the circle

B+C+D=180

150+C=180

C=180-150=30

The fraction of the circle to region C

The bowling alley and the swimming pool both offer birthday party rentals the bowling alley coast $5 per person plus a $15 room

Vanyuwa [196]

Answer:

Swimming pool

Step-by-step explanation:

Let's say that we invite x people. The cost of the bowling alley will be $15 for the room, and we add $5 dollars for each person. Therefore, we can represent the cost of the bowling alley as

5 * x + 15

Similarly, the cost of the swimming pool is

4 * x + 12

To find the maximum of the function, one thing we can do is set the expressions of the cost equal to 40. This will give us the amount of people we can invite for exactly 40 dollars. Because cost increases with amount of people, this will give us the maximum number of people we can invite with $40.

We thus have

5 * x+ 15 = 40

subtract 15 from both sides to isolate the x and its coefficient

25 = 5 * x

divide both sides by 5 to isolate x

25/5 = x = 5

We can therefore invite 5 people to the bowling alley

4 * x+ 12 = 40

subtract both sides by 12 to isolate the x and its coefficient

28 = 4 * x

divide both sides by 4 to isolate x

x = 7

Therefore, we can invite 7 people to the swimming pool. As 7 > 5, we can invite more people to the swimming pool.

A quicker way to solve this could be by looking at the cost of each location. Because the bowling alley costs more both per person and for the room, and there is no way to decrease the cost except by decreasing the amount of people, there is no way that the bowling alley could get as many people as the swimming pool with the same amount of money

A weather station on the top of a mountain reports that the temperature is currently 0 ∘ C and has been falling at a constant ra

LuckyWell [14K]

Answer:

After 2 hours: -6°C.

After 5 hours: -15°C.

After $\frac{1}{2}$ hours: -1.5°C

1 hour ago: 3°C.

3 hours ago: 9°C.

4.5 hours ago: 13.5°C.

To find these values, you simply need to multiply the hours elapsed by 3°C. Subtract from 0°C for future temperatures, and ADD to 0°C for the past.

Let's say you are solving for the temperature in 5 hours. All you need to do is:

3°C× 5= 15°C. 0°C-15°C= -15°C

For the temperature 3 hours AGO, what you will need to do instead is:

3°C×3= 9°C. 0°C+ 9°C= 9°C.

Which triangle is a 30°-60°-90° triangle?

Talja [164]

Answer:

the first one

Step-by-step explanation:

Hey There!

Look at the image for the rule of a 30- 60 - 90 triangle

x = 5

the hypotenuse would be x2 so 10

the longer leg would be x $\sqrt{3}$

So the first triangle is the right answer
