Andrew [12]

Answer:

Earnings current month of Michale = 3600

Step-by-step explanation:

Given that after the car payment is deducted, Michael take home pay will be $3060 per month. His monthly car payment is 15% of his earnings,

Let his earnings be 100

His car payment       15

His take home pay = 85

If 85 is take home pay earnings = 100

Hence if 3060 is take home pay earning = ?

This is a question of direct variation since if take home pay increases total earnings also increase.

So earnings = \frac{3060*100}{85} \\=3600

Earnings current month of Michale = 3600

A train is booked to do the run between two places 55 km apart,in 1 hr 20 min. if it travels for the first 30 km at 36km per hou
soldier1979 [14.2K]

Answer:

<em>The train must travel at 50 km/hr to make it on time.</em>

<em></em>

Step-by-step explanation:

distance to be covered = 55 km

time to cover this distance = 1 hr 20 min

1 hr 20 min = 1.33 hrs (20 min = 20/60 hrs = 0.33 hrs)

The train travels the first 30 km distance at a speed of 36 km/hr

and we know that time taken = distance/speed

therefore the time taken to run this 30 km will be

time = 30/36 = 0.83 hr

The train still has 55 - 30 = 25 km to cover,

and the time left is 1.33 - 0.83 = 0.5 hrs left

to make it on time, the train must travel at

speed = distance/time = 25/0.5 = <em>50 km/hr</em>

Destiny designs necklaces she used between 15 and 20 yellow and blue beads in a ratio of 4 yellow beads to 5 blue beads drag the
julia-pushkina [17]
Hey! :)

Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.4 : 5 ( = 9 too little )8 : 10 ( = 18 just right)12 : 15 ( = 27 too much)So per necklace, 8 yellow beads and 10 blue beads would be needed.

Hope this helps! :)
