To solve this, write a proportion of Pounds to Cost:
Pounds: 3 x
Cost: 25.50 42.50
Cross multiply 3 and 42.50, this gives you 127.5
Then, divide by 25.5
This gives you 5.
You can buy 5 pounds with $42.50
The rate of travel here is in mph - "miles per hour".
That just means how many miles you can travel in one hour. In this problem, you're given 15 hours, and the distance they travel within those 15 hours.
Therefore, you should divide both the number of miles and the number of hours by 15 to find out how far they can travel in 1 hour.
735 ÷ 15 = 49 miles
15 ÷ 15 = 1 hour
Their average rate of travel was 49 miles in 1 hour, which is 49 mph.
Answer:Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Because we are reflecting across the X-axis, the X coordinate does not change. On the other hand, the Y coordinate becomes its opposite. So we get:
(2, 4) -> (2, -4)
Answer: The answer is -3 1/2 - 1/5
so it's C.
