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 area of the shaded region is 46,77
Step-by-step explanation:
To determine the area of the shaded hexagon, we must first calculate te area of the whole shaded hexagon and minus that by the white little hexagon.
The formula to calculate the area of a hexagon is (3√3 s2)/ 2
(where s = one side of the hexagon)
if one side a the little white hexagon equals 6 ft;
3√3 6ft.2/2 = 18√3/2 = 9√3
now for the bigger hexagon where one side is 12 ft;
3√3 12 ft.2/2 = 72√3/2 = 36√3
now the area of the bigger one minus the area of the smaller one;
36√3 - 9√3 = 46,77
Answer:
right angle
Step-by-step explanation:
It has a 90 degrees angle
It would be 0.2
Because
1 divided by 5 = 0.2
To check
0.2*5=1
Hope this helps
Have a great day/night
First, find the area of each figure. Then subtract the smaller area from the larger area. Your work should look something like this:
A = l * w
A = 9 * 9
A = 81
This is the area of the smaller square. Now find the area of the larger square.
A = l * w
A = 15 * 15
A = 225
Now subtract the two areas to find the area of the shape that is left when the smaller square is cut out.
225 - 81 = 144
Your final answer should be:
144 in^2
