Answer:
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.
Explanation:
Let a be the capacity of old tank and b be the capacity of new tank.
A company added a new oil tank that holds 350 barrels of oil more than its old oil tank.
So we have b - a = 350 ----------------------equation 1
Together they hold 3650 barrels of oil
a + b = 3650 ----------------------equation 2
equation 1 + equation 2
2b = 3650 + 350 = 4000
b = 2000 barrels.
Substituting in equation 1
2000 - a = 350
a = 1650 barrels.
Capacity of old tank = 1650 barrels.
Capacity of new tank = 2000 barrels.

Answer:
Percentage of Pennies is 40
Step-by-step explanation:
Total coins are 600
Pennies are 240
Percentage of pennies = (240/600) × 100%
= 0.4 × 100%
= 40%
Answer:
a = 60°
60°, 60°, 120°, and 120°.
Step-by-step explanation:
Sum of interior angles of a quadrilateral = 360°
Therefore:
a° + a° + 2a° + 2a° = 360°
Add like terms
6a = 360
Divide both sides by 6
a = 60
2a = 2(60) = 120°.
Angle measure from least to greatest are 60°, 60°, 120°, and 120°.
