Answer:
At a speed of 57 mph for 8 hr a driver will travel 456 mi
Step-by-step explanation:
Here we have a summary of the letters for each variable:
Speed ---> r (in units of mph)
Time ---> t (in units of hr)
Distance ---> d (in units of mi)
These three variables are related by the next formula:
d = rt
In the data they give to you: 57 mph and 8 hr, they are telling you the r and the t, respectively:
r = 57 mph
t = 8 hr
The only thing you have to do is replace the values:
d = rt ----> d = 57 mph x 8 hr
d = 456 mi
Answer:
3/8ths cup
Step-by-step explanation:
take 3/4 and times that by 2 then you get 6/8th and then take half of the 6 out and get 3/8th
Answer:
C.
Step-by-step explanation:
The answer C is not rational
Answer:
Bottom left
Step-by-step explanation:
Because when you draw the graph you see that x is larger than 2 , and 2 is not including in the solution so, we just make a small lines (forget the y-axis).
I hope that it's a clear solution and explanation.
Remark
You must use the sin law to find this.

Multiply through by 12
12 *
*12

0.5269 = sin(x)
Now you have to use the inverse of the sine function.
Use your calculator for that
2nd F
sin-1
(0.5269)
= 31.79 degrees. <<<<<< Answer.
There sometimes is a second answer. I don't think there is in this case.
