Answer:
The two angles are 69° and 21°.
Step-by-step explanation:
Write out the expression:
let x and y be two angles that are complementary and the sum of their measures is 90°
-> x° + y° = 90°
if one angle is 6º more than three times the other angle:
-> x° = 6° +3y°
Plug x = 6+3y into x° + y° = 90°
6° + 3y° + y° = 90°
Solve for y
4y° = 84°
y° = 21°
Plug y into x° + y° = 90°
x° + 21° = 90°
Solve for x°
x° = 90° - 21° = 69°
Answer:
150 and -2 are integers
6.6 and -1/2 are rational numbers
-√3 is an irrational number
Step-by-step explanation:
Answer:
"The rate of Hose A is 1 gallon per minute more than the rate of Hose B"
Step-by-step explanation:
Hose A:
60 gallons every 15 minutes means
60/15 = 4 gallons per minute
Hose B:
y = 3x
y is gallons
x is minutes
we put x = 1 and get:
y = 3*1 = 3
That means 3 gallons per minute
Thus,
the correct choice is C), or third option. 4 is 1 greater than 3 so Hose A is 1 gallons per minute more than the rate of Hose B.
Answer:
The zero of the equation represents the maximum height attained by the shot put.
Step-by-step explanation:
William is competing in the shot put event at a track meet. The quadratic expression that models the vertical height of the shot from the ground is
H =
We can find the zeroes of these two equations.
For that put H = 0.
= 0
(-2x + 5)(x + 1) = 0
x= -1 or x = 2.5
x= -1 is neglected as it is not practical.
x = 2.5 is the maximum height attained by the shot put.
The zero of the equation represents the maximum height attained by the shot put.
