6(x - 6) +2x = 6(2 - 3x) + 4x - 2x
gogolik [260]

Answer:

x=2

Step-by-step explanation:

6(x-6)+2x=6(2-3x)+4x-2x

6x-36+2x=12-18x+4x-2x

8x-36=-16x+12

24x-36=12

24x=48

x=2

The water level in ricky lake changes at an average of -7/48 inch for 1 year.Based on the rate above how much will the water lev
bearhunter [10]

we are given

The water level in Ricky lake changes at an average of -7/48 inch for 1 year

It means that

In 1 year , the water level changes at \frac{-7}{48} inches

and we have to find the water level change after 5 years

so, we can multiply both sides by 5

In 5*1 year , the water level changes at 5*\frac{-7}{48} inches

In 5 years , the water level changes at \frac{-35}{48} inches

Hence,

the water level change after 5 years is \frac{-35}{48} inches........Answer

The Niagara Falls ferris wheel has a diameter of 48 meters, and one revolution takes 2.25 minutes to complete. Riders can see Ni
Yanka [14]

The time intervals when the riders could see Niagara falls are; 0.834 < t < 1.416 and (3.084, 3.666)

<h3>How to interpret Cycle Graphs?</h3>

From the diagram attached, we can say that;

Period = 2π/k

where;

k = 2π/2.25

k = 8π/9

Thus;

h(t) = -(48/2) cos (8π/9)t + ((48/2) + 0.5)

h(t) = -24cos (8π/9)t + 24.5

Riders can see Niagara falls if they are higher than 41 meters above the ground. Thus;

41 = -24cos (8π/9)t + 24.5

41 - 24.5 = -24cos (8π/9)t

16.5 = -24cos (8π/9)t

-0.6875 = cos (8π/9)t

cos⁻¹0.6875 = (8π/9)t

t = 0.834 min

Thus, time interval is between;

0.834 < t < (2.25 - 0.834)

⇒ 0.834 < t < 1.416 and

(2.25 + 0.834) < t < (2.25 + 1.416)

⇒ (3.084, 3.666)
