Answer:

  D)  3.250×10^4 days

Step-by-step explanation:

You know there are 24 hours in a day, so the number of hours must be divided by the hours per day to find the number of days:

  (7.8×10⁵ h)/(2.4×10¹ h/da) = (7.8/2.4)×10⁵⁻¹ da = 3.250×10⁴ da

A and B share the cost in a ratio of 3:2. A pays £125, how much does B pay?
jolli1 [7]
Cross multiply then solve for x:

3/2 * 125/x

2*125 = 250
3 * x = 3x

3x = 250
x = 83.33 = 83 (rounded)

The circumference of the earth is 2.4x109 miles. if you traveled at an average of 8.5x10 miles per hour, how long would it take
pshichka [43]

Answer:

282 hr   <======= see below

Step-by-step explanation:

Distance / rate = time

2.4 x 10^9 mi / 85 m/hr   = 28235294 hr

 You must have left the power of 10 off of your speed

     probably should be   8.5 x 10^6  perhaps?   then answer is 282

<h3>If speed was 8.5 x 10^5   then answer becomes ~ 2820   </h3>

What is the slope of the line whose equation is y−4= StartFraction 5 Over 2 EndFraction.(x−2)? A coordinate plane with a line pa
Katarina [22]

The slope of the given line is 5/2.

<h3>How to get the slope of the line?</h3>

The general linear equation can be written in the slope-intercept form as:

y = a*x + b

where a is the slope.

Here we have the equation:

y - 4 = (5/2)*(x - 2)

If we isolate y and expand the product in the right, we get:

y =  (5/2)*(x - 2) + 4

y = (5/2)*x - (5/2)*2 + 4

y = (5/2)*x - 5 + 4

y = (5/2)*x - 1

This is the linear equation in the slope-intercept form, as you can see, the slope is equal to 5/2.
