Step-by-step explanation:

assuming 90° is the central angle measure then the degree measure of the arc would be 90°

though the question asks for length

to do this create a ratio of the degree measurement of the arc divided by the total degree measure of a circle which would be

90/360

next think about circumference, it's the measure of the length around a circle. that would be relevant to what the question is asking so calculate it the formula is C=2*pi*r

calculate and the circumference is 24pi

next multiply the total circumference by the ratio for the section we want in this case 90/360

arc length = 24pi * 90/360 = 6pi

therefore the answer is 6pi or 18.84 substituting 3.14 for pi

Given points A (-5, 6) and B (7, -1), find: Distance, Midpoint, and Slope

a_sh-v [17]

We have that
<span>points A (-5, 6) and B (7, -1)

Part A)
find the distance
d=</span>√[(y2-y1)²+(x2-x1)²]-------> d=√[(-1-6)²+(7+5)²]----> d=√(49+144)
d=√193 units

Part B)
find the midpoint
ABx=(x1+x2)/2-----> (-5+7)/2-----> ABx=1
ABy=(y1+y2)/2-----> (-1+6)/2-----> ABy=2.5

the midpoint is (1,2.5)

Part C)
find the slope
m=(y2-y1)/(x2-x1)-----> m=(-1-6)/(7+5)--------> m=-7/12

the slope m=-7/12

Kenzie makes quilts from blue and purple pieces of fabric. The diagram shows the ratio of blue pieces to

REY [17]

The purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.

<h3>What is the ratio?</h3>

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The question is incomplete.

The complete question is in the picture, please refer to the picture.

Total number of pieces = 3+5 = 8

So, the purple pieces = 5(5/8) = 35

Total pieces = 20/(5/8) = 4×8 = 32

Thus, the purple pieces are 35 and total pieces is 32 if the Kenzie makes quilts from blue and purple pieces of fabric.
