Answer:
1. k=53.244 or k=13311/250
Answer:
0.5+8
Step-by-step explanation:
The slope intercept form is mx+b
Mx is the slope
b is the y intercept
The slope formula is y2-y1/x2-x1
2 points to find the slope:
(2,9) (4,10)
10-9=1
4-2=2
1/2=0.5
The y-intercept is the number that goes through the number line when x equals 0. The y intercept is 8.
Answer:
8 girls
Step-by-step explanation:
We want write a ratio to solve
3 boys 12 boys
------------ = -------------------
2 girls x girls
Using cross products
3x = 2*12
3x = 24
Divide by 3
3x/3 = 24/3
x = 8
There are 8 girls

Determine the formula of one of the triangular sections
From the attachment, we have that:
The area of the triangle is:
<u>How to know the formula works?</u>
From the attachment, we can see that the rectangle is divided into two equal triangular sections.
The area of the rectangle is:
Because the rectangle is divided into two equal triangular sections.
This implies that, the area of one of the triangular sections is half the area of the rectangle.
So:
Substitute LB for the area of the rectangle
By comparison:
and are the same
