Answer:
Area = 3,656.6 m²
Step-by-step explanation:
Area enclosed by the track is composed of two semicircles and a rectangle.
Area = area of two semicircles + area of rectangle
= 2(½*πr²) + L*W
Where,
radius of semicircle (r) = ½of 40 m = 20 m
Length of rectangle (L) = 60 m
Width of rectangle (W) = 40 m
Plug in the values
Area = 2(½*π*20²) + 60*40
Area = 400π + 2,400
Area = 3,656.6 m² (aooroximated to nearest tenth)
The scale factor would be -8 because...
126 inches / 7 inches = 8 inches.
Because the car is bigger than the scale, it would be a negative scale factor.
Answer:
1 7
-120 -22
Step-by-step explanation:
you need to do top left top right bottom left bottom. in order to move x to the other side you need to subtract then divide by the negative.
<span>y=2x+8 slope = 2
</span><span>parallel to y=2x+8, so equation has same slope = 2
</span><span>goes through point (−4,1)
</span>then
y = mx+b
1 = 2(-4) + b
b = 9
so the equation
y = 2x + 9
Answer: 2m-4
Step-by-step explanation:
2(m-5)+6
=2m-10+6
=2m-(10-6)
=2m-4
