Question 2: 231
question 3: 309,058,304
Answer:
gallon
Step-by-step explanation:
A gallon is a measuring unit used to measure the liquid capacity. It helps in measuring the volume and capacity of a fluid. The capacity of one gallon is equivalent to 3.79 liters. It is used to denote the measurement of approximately four liters of liquid.
Mrs. Larivierre had filled a tub with water. To measure the water content of the tub, the most appropriate unit would be a gallon.
Answer:4,1x101, 9, 4.1, 2, 0.42, 0.042
Step-by-step explanation:
B(t)=50×e^2.5t
e^2.5t = 20
t= ln(20) / 2.5
set B(t)=1000 and solve for t via 1000=50e2.5t
20=e2.5t
ln(20)=2.5t
t=ln(20) / 2.5
The barn, the ground, and the ladder form a right triangle. If we represent the height on the barn by y, then the Pythagorean theorem tells us
... hypotenuse² = (side1)² + (side2)²
... (12 ft)² = (3 ft)² + y² . . . . . . . . . . . . fill in given information
... 144 ft² - 9 ft² = y² = 135 ft² . . . . . .subtract (3 ft)²
... y = 3√15 ft ≈ 11.6 ft . . . . . . . . . . . take the square root
The ladder reaches 11.6 feet high on the barn.
