Answer: Slope-intercept form, y=mx+b, of linear equations, emphasizes the slope and the y-intercept of the line.
m(slope)=7/10 or (7,10)
4)
pine tree is most numerous on tree farm which is 40%
5)
if 480 trees total,
pine trees = 480 x 0.40 = 192 trees
6)
if 480 trees total,
spruce trees = 480 x 0.30 = 144 trees
(p.s. also firm trees = 144 (same as spruce trees)
Answer:
100:20 or 100/20 or 100 to 20
Answer:
A = 3.9 in²
Step-by-step explanation:
To find the area of the shaded region, you need to find the (1) area of the entire square, then (2) find the area of the 1/2 circles, then (3) subtract them and divide by 2. Because the 1/2 circles are identical, you can combine them and just use the circle area equation.
Area of the Square:
A = l x w
A = 6 in x 6 in
A = 36 in²
Area of Combined 1/2 Circles:
A = πr²
r = 6 in / 2
r = 3 in
A = π(3)²
A = 9π -----> 28.3 in²
Area of Shaded Region:
A = (Area Square - Area Circle) / 2
A = (36 in² - 28.3 in²) / 2
A = 7.7 in² / 2
A = 3.9 in²
