Answer:
x = 91.5
Step-by-step explanation:
for 30.5 miles travelled gas used is 1 gallon ← unit rate
To calculate distance travelled multiply gas used by 30.5
For 3 gallons used
distance travelled = 3 × 30.5 = 91.5 miles
⇒ x = 91.5
Answer: 24 students
Step-by-step explanation:
We know that there were 129 students total. However, of those 129 students, 9 traveled in cars, which means that only 120 students took the bus. We know there were five buses, so if the students filled the buses up equally, we can divide the number of bus riders by the number of buses to find the number of students per bus.
With 120 students and 5 buses, we get 120 ÷ 5 = 24.
250 units would be demanded when price is $11.67.
<h3>What is price elasticity of demand?</h3>
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
<h3>What is the price?</h3>
Percentage change in the quantity demanded = (250 / 200) - 1 = 25%
Percentage change in price = 25% / 1.5 = 16.67
Price = (1 + 0.1667) x 10 = 11.67

Answer: it will cost $280
Step-by-step explanation:
The diagonal of the rectangular garden divides it into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
d² = 24² + 32²
d² = 576 + 1024 = 1600
d = √1600
d = 40 feet
If the path is 2 feet wide, then the area of the path is
Area = 40 × 2 = 80 ft²
If gravel costs $3.50 a square foot, then the cost to install the gravel path is
3.5 × 80 = $280
