Asap! find the length of the arc
Fantom [35]

<u>Answer</u>:

A.  \frac{21}{4} \pi\ \space\ in

<u>Step-by-step explanation:</u>

The formula for arc length is:

arc length = rθ

where:

r is the radius = 7 in

θ is the central angle in radians = 135  ×  \frac{ \space\ \pi\ }{180}  = 3/4 π

Substituting these values into the formula:
arc length = 7 in × 3/4 π

                 = \frac{21}{4} \pi\ \space\ in

PLEASE HELP AS SOON AS POSSIBLE THANK YOU!!
nataly862011 [7]

Answer:

We know that when x= -10, y= -17.

So, if we put those into direct variation "y=kx", we get

-17= k(-10)

k   = -17 / -10

Now we put the value of "k" into the formula and we get A (y= 17/10x )

Which ratios are equal to 64 when the scale factor is 8? Select all that apply.
Luden [163]

Answer:

The scaled surface area of a square pyramid to the original surface area.

The scaled area of a triangle to the original area.

Step-by-step explanation:

Suppose that we have a cube with sidelength M.

if we rescale this measure with a scale factor 8, we get 8*M

Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2

This means that the ratio of the surfaces/areas will be 64.

(and will be the same for a pyramid, a rectangle, etc)

Then the correct options will be the ones related to surfaces, that are:

The scaled surface area of a square pyramid to the original surface area.

The scaled area of a triangle to the original area.

6.
Nimfa-mama [501]

Let's call our number <em>x</em>.

So we can setup the equation x² = 100.

To solve this equation, we square root both sides.

So we have x = ±10.

Always use plus or minus when square rooting both sides

of an equation so our answer is not only 10, it's also -10.
