Step-by-step explanation:
a) determine the rate in km/L
==> 9.5 L/100km = 10.526316 km/L
b) how far can the car travel with 475L petrol
==> 0.210526315789473km/l
c) how many litres of petrol do they need to travel 350 km
==>Liters per km (l/km)2.86×10-3
Liters per 10 km (l/10 km)0.03
Liters per 100 km (l/100km)0.29
Kilometer per liter (km/l)350
The numbers are 79, 80, and 81.
79+80+81=240.
Answer:
x = 34.06
Step-by-step explanation:
The sum of angles in the triangle LUV is 180 degrees
Given
∠L=(3x+y)°
∠U=42.6°
∠V=(4x−3y−0.8)°
Since ∠L+∠U + ∠V = 180 degrees
Substitute:
3x+y + 42.6 + 4x - 3y - 0.8 = 180
7x - 2y - 41.8 = 180
7x - 2y = 221.8 ... 1
Since UV = UL, hence the triangle is isosceles and <V = <L
3x+y = 4x-3y - 0.8
-x +4y = -0.8
x - 4y = 0.8 ....2
From 2: x = 0.8+4y
Substitute into 1:
7x - 2y = 221.8
7(0.8+4y) - 2y = 221.8
5.6 + 28y-2y = 221.8
26y = 221.8-5.6
26y = 216.2
y = 8.32
Get x
x = 0.8+4y
x = 0.8+4(8.32)
x = 0.8 + 33.26
x = 34.06
<em>Note that it was assumed that <V = <l since the question is not clear</em>
(3/4) of 440 miles = (3*440)/4 = N
If it takes one hour to travel 55 miles, how about N miles?
Time = N/55 = Answer
24 is the least common denominator
