Answer:
Step-by-step explanation:
since there is no given formula I'm guessing that's what we want to find?
use the dist. = rate * time formula for this kind of problem
or d = r*t ( this looks like the word "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt :P )
so Jean's rate is 64 MPH
her total distance is 448 miles
rearrange the d = rt formula so that you are solving for the thing you don't know.. yet.... t (time) for this case
soooo...
d/r = t
plug in number
448 / 64 = t
7 = t (in hours)
Answer: sin(34) = 0.52908268612
2/6 because there is a total of 6 points to get to 1. Thats is the 2nd point. 1 2/6 because its the 2nd point starting from 1 and 1 1/2 because that point is in the middle of 1 and 2
Well you find the unit rate of both rates. So 360/12=30 and 270/9=30. So both the rate are 30 miles per gallon

- |Absolute Value| - makes any negative number positive
Step-by-step explanation:
<u>Step 1: Define</u>
-3|5 - s³| + 3t
s = 2
t = 1.5
<u>Step 2: Evaluate</u>
- Substitute in variables: -3|5 - 2³| + 3(1.5)
- |Absolute Value| Exponents: -3|5 - 8| + 3(1.5)
- |Absolute Value| Subtract: -3|-3| + 3(1.5)
- Absolute Value: -3(3) + 3(1.5)
- Multiply: -9 + 4.5
- Add: -4.5
