Place a decimal point between the first two digits (4 and 8). Erase the commas and the 0s. So you'll have 4.86 left over after you've done that erasing.
Now ask yourself: "how many places to the right must I move the decimal to get 4.86 to turn back to 48,600,000?"
That would be 7 places to the right. That 7 is the exponent over the 10
<h3>Therefore, the answer is 4.86 * 10^7</h3>
This number is 48.6 million
Answer:
Step-by-step explanation:
A rotation of -90 degrees about the origin is equivalent to a clockwise rotation. Point A, initially at (2, 0), would become point A', (0, -2).
It's either 4 or 5, i think.
150 + 15x = 400
(-150) 150 + 15x = 400 (-150)
15x = 250
(/15) 15x = 250 (/15)
x = 16.67
So Chia can invite 16 people
