Find the measure of an angle with measure between 0° and 360° that is coterminal with an angle measuring –800°. °

expeople1 [14]

Just add 360 to -800 until you end up with an angle between 0 and 360:
-800+360=-440
-440+360=-80
-80+360=280

So the angle is 280 degrees.

In the inequality "y is less than or equal to 5 and is greater than or equal to -2," the product of the endpoints will be which

Licemer1 [7]

Answer:

(C) negative

Step-by-step explanation:

Inequality "y is less than or equal to 5 and is greater than or equal to -2":

- 2 ≤ y ≤ 5

This is the interval:

y ∈ [- 2, 5]

The endpoints are:

- 2 and 5

Product of the endpoints:

- 2 × 5 = - 10

Answer choices:

(A) odd ⇒ False, - 10 is even
(B) positive ⇒ False, - 10 is not positive
(C) negative ⇒ True
(D) None of the above ⇒ False, option C is correct

If 3 workers can paint a room in 2 hours, then approximately how long does it take 4 workers to paint the same room? Assume the

Olin [163]

It takes 1.5 hours for 4 workers to paint the same room

Solution:

Given that 3 workers can paint a room in 2 hours

To find: Time taken for 4 workers to paint the same room

Assume the time needed to paint the room is inversely proportional to the number of worker

$time $ \propto \frac{1}{\text { number of workers }}\\\\time =k \times \frac{1}{\text { number of workers }}$

Where, "k" is the constant of proportionality

3 workers can paint a room in 2 hours

Substitute number of workers = 3 and time = 2 hours

$time =k \times \frac{1}{\text { number of workers }}\\\\2 = k \times \frac{1}{3}\\\\k = 6$

Therefore,

$\text {time}=6 \times \frac{1}{\text { number of workers }}$

To find time taken for 4 workers to paint the same room, substitute number of workers = 4 in above expression

$time = 6 \times \frac{1}{4} = 1.5$

Thus it takes 1.5 hours for 4 workers to paint the same room
