<h3>Answer: C. 5</h3>

Explanation:

The term "collinear" means "the points are on the same straight line". The points A,B,C are on line m. So we have 3 collinear points so far.

The points D, B and E are on line n. That's another 2 collinear points.

This gives 3+2 = 5 collinear points overall.

The perimeter of a shape is 25.71 cm calculate the value of the radius X takes pie to be 3.142

Mariulka [41]

Answer:

5 cm

Step-by-step explanation:

Given a semicircle with perimeter 25.71 cm, we are required to find the radius of the circle.

Circumference of a Semicircle

=Length of the Circular part+Length of the diameter

$=\pi r+2r$

$If \: \pi=3.142, C=25.71\\Then:\\25.71=3.142r+2r\\r(3.142+2)=25.71\\5.142r=25.71\\r=25.71 \div5.142\\r=5cm$

Please help me thanks

BabaBlast [244]

Answer:

16.7

Step-by-step explanation:

We can use the Pythagorean theorem, a^2 + b^2 = c^2.

a = 11

c = 20

11^2 + b^2 = 20^2

121 + b^2 = 400

b^2 = 279

b = sqrt(279) = 16.7

What is the slope of the line?

sineoko [7]

Answer:

3/4

Step-by-step explanation:

You can do this two different ways. Both include picking two points where the line crosses a corner. I'm using (0,-1) and (4,2). Now here you can either use

Slope= $\frac{Rise}{Run}$

or $\frac{y2-y1}{x2-x1}$

If you use the first one start at point (0,-1) and go to point (4,2) and count how many it goes up (rise) and then put that over how many it goes to the right (run).

If you use the second one then plug in the numbers.

y2=second y point

y1=first y point

x2=second x point

x1=first x point

$\frac{2-(-1)}{4-0}$ Now just solve.

$\frac{3}{4}$
