Hello!
Use the Pythagorean Theorem to solve for x:
a² + b² = c²
We are given the lengths of two sides, so we can plug those into the formula:
9² + 12² = x²
81 + 144 = x²
225 = x²
√225 = x
x = 15.
Answer:
There is a answer to the question and with the steps
For A, divide total miles by the miles per gallon for each tire pressure to find the number of gallons of gas used:
At 30 psi: 23000 / 20.5 = 1121.95 gallons , round to 1121 gallons.
At 35 psi: 23000 / 21.1 = 1090 gallons.
Number of gallons saved: 1121 - 1090 = 31 gallons.
B) multiply the cost per gallon by the number of gallons saved:
31 gallons x $2.00 = $62.00 saved.
C) Multiply the gallons saved by 1 car by total number of cars:
31 gallons x 140 million cars = 4,340 million gallons ( 4 billion 340 million gallons)
Answer:
2/3 = 0.6666666666666667 or just 67%.
Step-by-step explanation:
Hello
1 km = 1000 m
12 km = 12,000 m
Each day, she runs 10 * 400 m = 4000 m
12,000 m / 4000 m = 3
It will take 3 days.
Have a nice day
