Each spoke is 4.3 inches long.
Since the spoke is from the center of the wheel to its rim, we are looking for the radius of the circle.
Circumference = 2πr
27 = 2(3.14) r
27 = 6.28 r
27/6.28 = 6.28r/6.28
4.30 = r
D.perpendicular as perpendicular lines create 90 degree angle.
Answer:
8,5
Step-by-step explanation:
5*8-2y=30
40-30=2y
10=2y
y=10/2
y=5
Answer:
a) 200 mm^2
b) 500 mm^2
c) 3.75e + 8
d) 6390 cm^2
e) 650 cm^2
f) 20 m/s
Step-by-step explanation:
For a) and b): 1 cm = 10 mm, multiply 20 (and 50) by 10
For c): the formula is to multiply 1e + 8
For d): 1 Liter = 1000 Cubic Centimeters (hopefully that's what you're referring to)
For e): 10 mm = 1 cm, divide by 10
For f): divide the value by 3.6
Answer:
-31/26
Step-by-step explanation:
To find the slope
m= ( y2-y1)/(x2-x1)
= ( 15 - -16)/(-7 - 19)
= ( 15+16)/(-7-19)
= 31/ -26
-31/26
