Rational radical 2 times radical 8 is radical 16 which is 4
Answer:
45h=d
Step-by-step explanation:
If d represents the distance in miles, then the equation would be 45h=d because when you multiply 45 by the amount of hours h, then you would get the total distance in miles. For example, Oliver drives 45 miles per hour for 3 hours. When we substitute h, the number of hours, for 3, then we get:
45(3)=d
And all we need to do is to multiply them together to get d, which in this case, it is 135 miles.
Answer:
400m of fencing is required to surround the area.
Step-by-step explanation:
First we need to find one side of the square. We know the area of a square is:
A = x²
We can use this information to find the length of a side of the square.
10000m² = x²
x = √10000m²
x = 100m
Now that we know what the length of the square yard is, we can calculate the perimeter. The perimeter of a square is:
P = 4x
For our problem:
P = 4(100m)
P = 400m
400m of fencing is required to surround the area.

Your interest formula is given to you.
<span>Interest in a year = principal (the amount invested) * rate (the interest rate) * period (the time you're measuring) </span>
<span>Interest = 55,000 * 2% * 1 year = 55,000 * 0.02 * 1 = $1,100 </span>
<span>How much would you need to have made for your spending power to keep with inflation? Your interest rate would have needed to match the inflation rate, otherwise, prices are going up faster than you're saving. </span>
<span>Required interest = 55,000 * 3.24% * 1 year = 55,000 * 0.0324 * 1 = $1,782 </span>
<span>How much buying power did you lose? The difference between your required interest and your actual interest. </span>
<span>Buying power lost = 1,782 - 1,100 = $682. You lost this much in buying power. </span>
