A)
distance covered
5*2/3 = 3.333
time taken = 21min
this means it takes
5*<span>6.306 = 31.53 to covers 5 km
b) </span><span>21min/3.33 = 6.306 time taken to ran 1 km</span>
Car 1 consumes 30 gallons of gas.Car 2 consumes 20 gallons of gas.
Answer:
area= 1/2*(h*b) h- height, b- base
the triangle is isosceles (denoted by the 2 dashes on the sides of the triangle)
so they are equal in length
angles in triangle = 180
so 38+38=76
180-76=104
base=24
divide the triangle in the center
so now triangle 1(left) the base = 12
and triangle 2(right) the base = 12
use trigonometric ratios
in this we need to find the height
which is opposite of 38,
we already have the adjacent =12
so the ratio is Tan (Tangent Opposite/Adjacent)(TOA)
Tan38= (12/h)
multiply by h
h*Tan38=12
h=12/tan38 = 15.35929959
