The unknown is the distance in kilometres
The given is the distance in miles=140 miles
1 mile=1.6093km
140 miles=?
140/1*1.6093km=225.302km
Therefore the 140 miles in km is 225.302km
Answer:
Step-by-step explanation:
6y = -3x - 3
y = -1/2x - 1/2
perp. 2
y + 5 = 2(x - 1)
y + 5 = 2x - 2
y = 2x - 7
Answer:
100,80
Step-by-step explanation:
The opposite angle theorem states that, : "When two lines cross four angles are created and the opposite angles are equal."
y°=80°
Now, check that , x° and y° are in one straight line. A straight line has angle of 180°. So x° and y° should sum up to 180°
x° + y° = 180°
x° + 80° = 180°
x° = 100°
Volume of cone formula: V = PI x r^2 x h/3
Volume of sphere formula: 4/3 x PI x r^3
Cone: 3.14 x 9^2 x 9/3 = 763.02 cubic inches
1/2 sphere: 1/2 x 4/3 x 3.14 x 9^3 = 1526.04 cubic inches.
Total volume : 1526.04 + 763.02 = 2289.1 cubic inches
