Answer:
16
Step-by-step explanation:
Set up the following proportion
75 miles / 4 gallons = 300 miles / x Cross multiply
75x = 4 * 300
75x = 1200 Divide by 75
x = 1200/75
x = 16 gallons
Answer:
Ben receives 75%
Step-by-step explanation:
sum the parts of the ratio, 1 + 3 = 4 parts
Ben receives 3 parts of the 4 , that is
× 100%
= 0.75 × 100%
= 75%
Answer:
see explanation
Step-by-step explanation:
∠CBA = ∠BAG = 28° ( Alternate angles )
∠EAD = 90° - ∠BAG = 90° - 28° = 62° ( ∠EAG is right )
∠EDB is an external angle of ΔADE
• The external angle is equal to the sum of the 2 opposite interior angles
∠EDB = x + 4x = 5x
5x = 3x + 62 ( subtract 2x from both sides )
2x = 62 ( divide both sides by 2 )
x = 31, hence
3x = 3 × 31 = 93° and 4x = 4 × 31 = 124°
