Arianna went running for 0.75 hours and ran 5.55 miles. What was her speed, in miles per hour, if Arianna ran at the same speed for her whole run?

7.4 miles per hour

Step-by-step explanation:

To find her speed in miles per hour, divide the amount of miles she ran by the number of hours:

5.55/0.75

= 7.4

So, her speed is 7.4 miles per hour

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
