Step2247 [10]
Hi! =)

So,<em> 1 </em>lbs per week are equal to<em> 7.4999e-7</em> kilograms per second. We can use this to convert lbs per week to kg per second.

<em>721 * 7.4999e-7 = 0.000540741!</em> =)

EASY POINTS (attached)
solong [7]
Answer for the first one - it's complicated, but that maths is correct

I kind of cheated and did it a different way than they'd expect. By doing 24 squared, that gives you 576. 

since both angles are 45 degrees, then the sides are equal lengths. Therefore x squared times 2 = 576.

Because of this, x squared = 576 divided by 2, which equals 288.
Therefore the square root of 288 = 12 square root 2

One number is 3/8 of another number. The difference of the two numbers is 4.2. What is the lesser number
boyakko [2]

Answer:

2.52.

Step-by-step explanation:

If one number is x then the other = 3x/8.

Also x - 3x / 8 = 4.2

x - 0.375 x = 4.2

0.625x = 4.2

x = 4.2 / 0.625

x = 6.72.

So the lesser number is 6.72 * 0.375 = 2.52.
