Answer:
111 cars
Step-by-step explanation:
30% of 78 is
78×30%=78×0.3=23.4
Cars needed to sell
78+23.4=111.4
Unless we can't have 0.4 of a car, we need to round that number, so 111.4≈111
Ratio of the length of the tile to the length of the board is 1:2
Ratio of the area of the tile to the area of the board is 1:4
Step-by-step explanation:
- Step 1: Find ratio of length of the tile to the length of the board
Length of the tile = 1/4 ft
Length of the board = 1/6 yd = 1/6 × 3 = 1/2 ft (∵ 1 yd = 3ft)
∴ Ratio of length of the tile to length of the board = 1/4 : 1/2 = 1/4 × 2/1 = 1:2
- Step 2: Find the ratio of area of the tile to area of the board
Area of the tile = Length × Width = 1/4 ft × 1/4 ft = 1/16 ft²
Area of the board = Length × Width = 1/6 yd × 1/6 yd
= 1/2 ft × 1/2 ft (∵ 1 yd = 3 ft)
= 1/4 ft²
⇒ Ratio of the area of the tile to the area of the board = 1/16 : 1/4
= 1/16 × 4/1 = 1:4
Answer:
Yes it is.
Step-by-step explanation:
For a triangle to be a right angled triangle, it needs to verify the pythagoras theorem which is
h² = p² + b²
where h is the longest side.
So,
15² = 12² + 9²
225 = 144 + 81
225 = 225
which is true.
So the triangle is a right angled triangle.
