Answer:
x = 2
y = 152°
Step-by-step explanation:
✔️9x + 10 = 15x - 2 (corresponding angles theorem)
Collect like terms
9x - 15x = -10 - 2
-6x = -12
Divide both sides by -6
x = -12/-6
x = 2
✔️y + (15x - 2) = 180° (same-side interior angle theorem)
Plug in the value of x
y + (15*2 - 2) = 180
y + 28 = 180
y = 180 - 28
y = 152
Answer:
53.44 cubic meters
Step-by-step explanation:
A cylindrical oil drum is 2.1 meters high and has a radius of 0.9 meters. How many cubic meters of oil can the drum hold? (volume)
Volume of a cylinder = π × r² × h
r = 0.9 meters
h = 2.1 meters
= π × (0.9m)² × 2.1m
= 53.44 cubic meters
Therefore, the volume of the cylindrical oil drum = 53.44 cubic meters
Answer:
v = 48
Step-by-step explanation:
8 = v/6
Step 1: Multiply both sides by 6.
8 × 6 = v/6 × 6
v/6 cancels out and becomes v
48 = v
Step 2: Flip the equation.
v = 48
Answer: center (0,0), vertices (+/-5,0), foci (+/-4.6,0)
