3. The sum of the measures of a complement and a supplement of an angle is 200. What is the measure of the angle?
klasskru [66]
Hi there!

Let th' required angle = X

Then,

• Complement of th' angle = 90 - X
• Supplement of th' angle is = 180 - X

According to th' question,
Sum of Complement and Supplement :-

(90 - X) + (180 - X) = 200

⇒ 90 - X + 180 - X = 200

⇒ 270 - 2X = 200 

⇒ 2X = 270 - 200

⇒ 2X = 70 

⇒ X = \dfrac {70}{2} = 35

Hence,
Th' measure of the angle is 35°

~ Hope it helps!

Answer:

This is a line, x>0  (miles cannot be negative)

Step-by-step explanation:

Cost of renting a car =  cost per mile times the number of miles  plus the flat fee

We know the cost per mile = .25 and the flat fee

Let x = number of miles and y = cost of renting a car

y = .25x+15

This is in the form y= mx+b which is  the slope intercept form of a line.

Answer:

B

Step-by-step explanation:

The questions says that the graph is shifted down 7 units, which means it will affect the y-intercept.

1. What is the range of frequencies a human ear can hear?
zubka84 [21]

Answer:

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz.

(Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
