275×2 would be how many miles she drove in 10 hours rght ? 275×2=550
550 miles in 10 hours
we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550
10 hours plus 3 hours = 13 hours right ?
55 ×3 = 165
550 +165=715
715 miles in 13 hours
Step-by-step explanation:
715÷13 to get how many miles she drove in one hour .
=55 miles in 1 hour .
then multiply 55 ×5 to get how many miles she drove in 5 hours
55×5=275
275 miles in 5 hours
Equation of a line is given by y - y1 = m(x - x1); where m is the slope.
y - 4 = 2/5 (x - (-2))
y - 4 = 2/5 (x + 2)

Answer: The height of building is 311 feet and the height of statue is 15.6 feet.
Step-by-step explanation:
Let the height of the building be 'b' and the height of the statue be 'g'.
Then according to the question, we get the following equation

Now, add both the equations, we get

Substitute the value of b in equation (2), we get

Hence, the height of building = 311 feet and the height of statue =15.6 feet.
60 x 5 = 300 days
So five half-lifes = 300 days
Starting amount = 500mg
<span>Amount after 1st half-life = 250 mg</span>
<span>Amount after 2nd half-life = 125 mg</span>
<span>Amount after 3rd half-life = 62.5 mg</span>
<span>Amount after 4th half-life = 31.25 mg</span>
<span>Amount after 5th half-life = 15.625 mg</span>
<span>Hence after 300 days, the amount of iodine-125 will be 15.625 mg out of 500 mg.</span>
