Since 16 out of 24 kids take the bus, 16/24 kids take the bus. We can reduce this fraction by dividing both the numerator and the denominator by 8. Now, our fraction becomes 2/3. 2/3 is the number in a fraction.
In order to convert this into a decimal, we divide the numerator by the denominator. 2/3 = 0.67, so 0.67 is the decimal.
To convert this to a percentage, we multiply it by 100. 0.67*100 = 67, so the percentage of kids who ride the bus is 67%.
Answer:
a) 27 m/s
b) 30 m/s
c) i) 3
ii) Deceleration
Step-by-step explanation:
The question is not complete, the correct question is given as:
The graph shows information about the speed of a vehicle during the final 50 seconds of a journey. At the start of the 50 seconds the speed is k metres per second. The distance travelled during the 50 seconds is 1.35 kilometres.
(a) Work out the average speed of the vehicle during the 50 seconds
(b) Work out the value of k.
(c) (i) Calculate the gradient of the graph in the final 10 seconds of the journey
(ii) Describe what this gradient represents
Answer:
The graph is attached. The total time = 50 seconds, total distance = 1.35 km = 1350 m
a) The average speed is the ratio of the total distance traveled to the total time taken to cover this distance. The average speed is given by the formula:
b) From the graph, the total distance covered is the area of the graph. The graph is made up of a rectangle and triangle, the area of the graph is equal to the sum of area of rectangle and area of triangle.
c) i) The gradient in the last 10 seconds is the ratio of change in speed to change in time
ii) Since the gradient is negative it means it is deceleration. That is in the in the last 10 seconds the vehicle decelerates at a rate of 3 m/s²
Yes she will have left overs. The amount of left overs is 5. Because 5x25= 125. You can also do long division to solve it
Answer:
3608 L
Step-by-step explanation
You just have to multiply the dimensions and then divide by 1000 which is amount of cm3 per liter
Sentence 2: left I don't know if that quailifys as a answer...
