Answer:
45 miles.
Step-by-step explanation:
Given that the:
Total distance covered = 390 miles
Total time = 8 hours
Let the distance covered along the local way = L
And the distance covered along the highway = H
Along with local way,
Speed = distance/ time
20 = L / T
T = L /20 .... (1)
Along the highway,
Distance covered H = 390 - L
Let the time = t
Speed = distance/time
60 = (390 - L)/t
t = ( 390 - L)/60
But total time = T + t
That is
8 = L/20 + (390 - L)/60
The LCM at right hand side will be 60
8 = ( 3L + 390 - L )/60
Cross multiply
480 = 2L + 390
Collect the like terms
2L = 480 - 390
2L = 90
L = 90/2
L = 45 miles.
Therefore, the distance Minato drive along local roads is 45 miles

In a right triangle the biggest angle is 90°.
Then the two smaller angles sum up 180° - 90° = 90 °.
Now you can use this equation: 3x + 6 + 2x - 1 = 90 and solve for x:
5 x + 5 = 90
5x = 85
x = 85/5
x = 17
Then, the smallest angle is 2(17) - 1 = 33°
A triangular pyramid is a figure made only with triangles, and it has 4 triangles.
A triangular prism has a triangular base and rectangles as lateral faces.
A cylinder has a circle as its base and a curved rectangle as the lateral face.
A cone has a c
Answer:
-1152
Step-by-step explanation:
F(1)=-16
F(2)=-28
F(3)=-40
Notice the sequence is decreasing by -12 for every increase in x
You can conclude the function for this sequence is going to be
F(x)=-12x
Plug 96 as X.
F(96)=-1152
