Answer:729

Step-by-step explanation:X would be 7, so that would make 27^2, and 27^2 is 27x27, because it is 2 27s. Therefore, 27x27 equals 89, drag the 4 above the 2, and multiply the 7 with the top 2, and you mark out the 4 and put 1 over it. The answer for that would Ben 189, put down your denominator, and multiply the second 2 with 7 and the 2 above that 2, and then you get 540, and then you add the 189, 1 over that one, and plus it with 540, which would equal 729. Sorry if I made it sound confusing, I tried. Hope this helps, though!

How many miles will a person run during a 10 kilometer race?

faltersainse [42]

There are 1,61 kilometers in a mile or more correctly 1,60934 kilometers in a mile.
<span>But first, a short history.... Both kilometers and miles are units of measurement. They are used to measure distance. Miles are part of the imperial measurement system and kilometers are part of the metric measurement system. </span>
To calculate how many miles a person will run during a 10-kilometer race, you need to divide 10 kilometers by 1,61 miles (1,60934 rounded up to two digits).

Therefore your equation is as follows:

10÷1,61 or 10 000 meters ÷ 1 610 metres
1000 meters is equal to 1 kilometer.

The answer = 6, 21 miles.

Therefore, a person who runs 10 kilometers will run 6,21 miles

The focus of a parabola is (0, -3) and the directrix is y = 3. What is the equation of the parabola?

mart [117]

Focus has coordinates (0, a)
a = -3
Thus, 4a = 4(-3) = -12

Because a is negative, we know it will be a concave down or concave left parabola. Hence, A and D can be eliminated. And we know it has to be B because the directrix is the horizontal line y = 3. Hence, the equation of the parabola becomes:

$x^{2} = -12y$ or $y = -\frac{1}{12}x^{2}$
