Answer: 12000 meters
Step-by-step explanation: 1 kilometer=1000 meters. he walked 12 kilometers in 3 days, which when multiplied by 1000, comes out to be 12000 meters.
Her unit rate would be either 4 mph or 1/4 mph. For 4 mph, you have to multiply 2/3 * 6/1 =4. For 1/4, you have to multiply 1/6 * 3/2 =1/4.
Answer:
66.667%
Step-by-step explanation:
In a fair die, there are 6 possible rolls. Out of the 6, 1 number is chosen each time. Since order does not matter in this problem, we will be applying combination, so this would be written as 6C1 x 4. In order to exclude 3 and 4, from 6, the choices must be narrowed down to 4. Written out as an equation, this would be 4C1 x 4. To get the percentage, simply divide the two equations.
(4C1 x 4)/(6C1 x 4) = 0.66667 = 66.667%
Answer:
The perimeter of the playground is 65 metres
Step-by-step explanation:
Questions like this requires attachment; See attachment for diagram.
From the diagram, we have the following parameters
Required
Calculate the parameter of the actual diagram
First, the actual length and width has to be calculated;
Given that the scale drawing is 1:500
Now, the perimeter can be calculated;
However, the question requires answer to be in meters
If 100 cm = 1 m, then
Hence, the perimeter of the playground is 65 metres
