I don’t know the answer I can’t see the question that you are asking for

You might be interested in

which is the rationalized form of the expression the square root of x divided by the square root of x +the square root of 7

Ilya [14]

Answer:

I assume your goal is to rationalize the denominator -

So you need to multiply the denominator by its conjugate.

So we have:

$\frac{\sqrt{x} }{\sqrt{x}-\sqrt{7} } *\frac{\sqrt{x} +\sqrt{7} }{\sqrt{x} +\sqrt{7}}$

$\frac{x-\sqrt{7}\sqrt{x} }{x-7}$

Beinggreat78 answer fast please :')

Answer:

17662.5 sq. feet

Step-by-step explanation:

We know that the formula for Area of a Circle is $A = \pi (r)^2$ .

r = radius; d = diameter, which is r*2

And so, in the question, it gives you that the diameter is 150, first we divide it by 2 to get the radius.

150/2 = 75

The question said to keep $\pi$ =3.14, so then we plug in the equation-

$A = 3.14 * 75^2$

Then we use PEMDAS [Parenthesis; Exponents; Multiply & Divide; Add & Subtract] which would get us-

$A = 3.14 * 5625$ (first doing the Exponent)

And we continue-

$A = 17662.5$ (then multiple)

So our answer is-

17662.5 sq. feet

I hope this helps!
Please give brainliest!

Have a great day

Which equation can be used to solve for m∠1? m∠1 = One-half(a – b) m∠1 = One-half(a + b) m∠1 = One-half(c – d) m∠1 = One-half(c

Artemon [7]

Answer:

$m\angle 1=\frac{1}{2}(arc\ a+arc\ b)$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The measure of the<u><em> interior angle</em></u> is the semi-sum of the arches that comprise it and its opposite.

$m\angle 1=\frac{1}{2}(arc\ a+arc\ b)$
