Answer:
x = 10
Step-by-step explanation:
For the lines to be parallel, the two angles must have the same measure:
80 - x = 90 - 2x
x = 10 . . . . . . . . . add 2x-80
The value of x must be 10 to make the lines parallel.
Answer:
7/8
Step-by-step explanation:
7/5•5/8= 7•5/5•8
= 35/40
=7/8

(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
<u>Given that</u> :
Diameter (d) = 18 cm
Pi (π) = 3.14
Radius (r) = d/2 = 18/2 = 9 cm
We know that volume of sphere is
Volume of Sphere = 4/3πr³
Volume = 4/3 × 3.14 × (9)³
Volume = 4/3 × 3.14 × 729
Volume = 4 × 3.14 × 243
Volume = 12.56 × 243
Volume = 3052.08
<u>Hence, the volume is 3052.08 cm³</u>
Suzy: (7 days)(5/4 miles per day) = 35/4 miles
Gretchen: (7 days)(3 miles per day) = 21 miles
Subtracting, 21 miles less 35/4 miles = 49 miles (difference)
