I think the answer is C

Answer: C, I think!

Step-by-step explanation: 3pi equals 9.4247. The square root of 100, is 10. So, that gives us 10/4. That simplified gives us 2.5.

For A, the square root of 36 is 6. 6 is in between 2.5 and pi, so that is not it.

For B, pi to the second power over 3 equals 3.2897, so that’s not it too!

For C, pi over 2 is 1.5708, so that is it, I’m pretty sure!

I’m only in 7th grade, so I’m sorry if it’s wrong!

Sorry if I made typos!

Prove or disprove that the point (√5, 12) is on the circle centered at the origin and containing the point (-13, 0). Show your w

pav-90 [236]

Using the equation of the circle, it is found that since it reaches an identity, the point (√5, 12) is on the circle.

<h3>What is the equation of a circle?</h3>

The equation of a circle of center $(x_0, y_0)$ and radius r is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

In this problem, the circle is centered at the origin, hence $(x_0, y_0) = (0,0)$ .

The circle contains the point (-13,0), hence the radius is found as follows:

$x^2 + y^2 = r^2$

$(-13)^2 + 0^2 = t^2$

$r^2 = 169$

Hence the equation is:

$x^2 + y^2 = 169$

Then, we test if point (√5, 12) is on the circle:

$x^2 + y^2 = 169$

$(\sqrt{5})^2 + 12^2 = 169$

25 + 144 = 169

Which is an identity, hence point (√5, 12) is on the circle.

8th grade linear functions, will give brainliest if the steps are listed and explained :)))

Rom4ik [11]

Get the slope of the line using the two known points:

slope = (7 3/4 - 6 1/4) / (1 1/4 - 3/4) = (1 2/4) / (2/4) = 3

Use the point-slope formula for a line to get the equation of the line. You can use any of the known points and the slope computed above. For example,

y - 6 1/4 = 3 (x - 3/4) ⇒ y = 3x + 16/4 = 3x + 4

Then for some given value of x, the third point has y-coordinate 3x + 4.

"Which values" suggests there may be more to the question, namely some list of answer choices. If you have something like that, just check if the above condition is met.

if the cost of a dress is multiplied by 5/8 the price then becomes $30.00 what was the original price

Alik [6]

Let's label the original price of the dress as x. We know that
$x \times \frac{5}{8} = 30$
so that means that we can find x by dividing both sides by 5/8:
$x = 30 \div \frac{5}{8}$
A simple rule for dividing fractions is 'Keep Change Flip'. You keep the first number/fraction the same, you change the ÷ to a × and you flip the second fraction. Through this rule, we can now solve the equation much more easily:
$x = 30 \times \frac{8}{5} \\ x = \frac{240}{5} \\ x = 48$
Therefore, the original price of the dress was $48
