Answer:
10^-3
Step-by-step explanation:
so if you have 10^2/10^5, you would subtract the exponents since it is division. 2-5=-3
therefore, it would be 10^-2
Hope this helps!
Answer:
y = 1/2 x -14.5
Step-by-step explanation:
2x-4y=58
solve for y
subtract 2x from each side
2x-2x-4y = -2x+58
-4y = -2x+58
divide by -4 on both sides
-4y/-4 = -2x/-4 +58/-4
y = 1/2 x -14.5
Positive 28 because it’s above the ocean so it’s in the positive see it make sense so if it was below sea level it would be negitive
The answer is the 2 one Bc it was the divided
Answer:
8 units
Step-by-step explanation:
Hello!
So, there's a formula we can apply to right-angled triangles: Pythagorean's theorem. It states that c =
, where <em>c</em> is the hypotenuse and <em>a</em> and <em>b </em>are the legs of the triangle.
So, from the problem, if <em>c </em>= 17 and <em>a </em> = 15, then, we're solving for <em>b</em>. So we'll rewrite the theorem to solve for <em>b</em>.

Okay, so now we have isolated the theorem for <em>b. Let's </em>plug in our values for <em>c </em>and <em>a</em>.

So, using the theorem, we found <em>b</em> = 8. To check our work, let's plug in <em>b</em> and <em>a</em> and solve for <em>c.</em>

So, we got our hypotenuse to equal 17 units, which is correct! So, our <em>b</em> is correct too. Awesome
