Answer:
D. 3:00 p.m.
Step-by-step explanation:
d = Distance = 320 miles
s = Speed = 
Time taken is given by
40 minutes break is 
Total time taken is 
.
So, the entire trip took 6 hours. 6 hours after 9 a.m. is 3 p.m.
Since multiplicative inverse is the same thing as reciprocal, the multiplicative inverse is just the denominator and the numerator flipped. So the multiplicative inverse of -7/9 is 9/-7. Hope this helps! If you ever need any more help in math you could always DM me.
Answer and Explanation:
In the equation y=5x the slope (m) is 5, and the y-intercept is the point (0,0) since there is nothing added or subtracted to the 5x, and thus b = 0.
3k + 15 = 66
3k = 66 - 15
3k = 51
k = 51/3
k = 17
Divide the c<span>omposite figure into 2 pieces, so then you have a rectangle and a trapezoid.
</span>
area of rectangle = 6 x 8 = 48
area of trapezoid = 1/2(4+8)(6) = 36
so
area of composite figure = 48 + 36 = 84 m^2
