Answer:
6,4,3
Step-by-step explanation:
A coefficient is a number multiplied by a variable in the a equation. 6 is not a coefficient because it is not being multiplied by anything
Answer:
62.82
Step-by-step explanation:
C=2πA=2·π314≈62.81592cm
D = k/c
2 = k/17
k = 2 x 17 = 34
Required equation is d = 34 / c
Answer: 48 gallons
Step-by-step explanation:
Given: Previous rate of dispensing water= 9 gallons per min
If Reyna use 8 min showerhead then
Total amount of water dispensed=
After Reyna changed the showerhead to energy saving with equation
y=3x, where y is the amount of water dispensed as a function of the number of x minutes for the new showerhead.
When we put x=8 minutes, we get total amount of water dispensed=
Water saved by Reyna=72-24=48 gallons
Answer: 289 ft.
Explanation:
You can form a right triangle with these features:
1) Base = adjacent-leg = 500 feet
2) angle between the hypotenuse and the base = 30° ( I use 30° instead of 30', because 30' does not make sense, it is a too small angle)
3) Height = opposite-leg = height of the Statue of LIberty = x
Now, use the equation for the trigonometric ratio tangent:
tan(angle) = opposite-leg / adjacent-leg
=> tan (30°) = x / 500ft
=> x = 500ft * tan(30°)
x = 288.67 ft which rounded to the nearest foot is 289 ft.
