It will take Wanda and Miranda 0.375 hours to be 9 miles apart

Wanda's speed = 6 miles per hour

Miranda's speed = 30 miles per hour

Distance = Speed x time

Find the distance covered by Wanda in t hours

D_{wanda} = 6t

Find the distance covered by Miranda in t hours

D_{miranda} = 30t

Difference in the distances covered

D_{miranda} - D_{wanda} = 30t-6t\\\\D_{miranda} - D_{wanda} = 24t

The difference in their distance is 9 miles

9 = 24t

To find the time, divide both sides by 9

\frac{9}{24} = \frac{24}{24}t\\\\t =   \frac{9}{24}\\\\t = 0.375

It will take Wanda and Miranda 0.375 hours to be 9 miles apart

What is the equation of a line that contains the points (2,-2) and (0, -2)?
Zolol [24]

Answer:

y = - 2

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

Where c is the value of the y- coordinates the line passes through

The line passes through (2, - 2) and (0, - 2) both with y- coordinate of - 2, thus

Equation of line is y = - 2

Can some show the steps and the answer please I really need help tell me how you get it and the answer
Tems11 [23]

Answer:

Step-by-step explanation:

here is some helpful trig function reminders.. copy this and keep it

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

they ask how long is the ladder

they give us the opposite side (8) and the adjacent side (6)  

and the Hyp is the length of the ladder.   They expect you to sort this out in your head.  :/  

there is two steps .. we'll solve for the angle.. then we can use that to find the Hyp side..(long side of triangle)  which is the ladder length

Tan(Ф) = Opp / Adj

Tan(Ф) = 8 / 6

Ф = arcTan(8 / 6)

Ф ≈ 53.130°

now lets use that angle with one of the other trig functions to find the Hyp.. sin or cos will work b/c we have both the opp and the adj sides lengths.  let's use cos

Cos(53.130) = 6 / Hyp

Hyp = 6 / Cos(53.130)   ( I just used algebra to swap the two)

Hyp = 9.99997

the ladder will be 10' long.  

ask in the comments if you need any more explaining

3/4 Tones = __ lb????<br><br> HELP ASAP <br><br> Thank you
Shtirlitz [24]
The answer is 1500 pound because 1 ton = 2,000 pounds. 1/4 of a ton = 500 pounds. So 3/4 tons = 500*3 =1500 pounds.
