You originally start out with 28 marbles. each marble has a number out of 28 to create a percentage. 21/28 or 75% signifies red, 4/28 or about 14% is white and 3/28 or about 11% is gray. add white and gray, which is 7/28 combined or 25% together. multiply by number of times the process is completed, which is 112 and the final answer is 28
Answer:
<u>The track consumes ≅ 61 liters of fuel every 100 kilometres</u>
Step-by-step explanation:
As we can see in the graph, the total distance that the truck can travel with 500 liters of fuel is ≅ 825 kilometres.
For answering the question properly, we use the Rule of Three Simple, this way:
Kilometres Liters of fuel
825 500
100 x
Solving for x, we have:
825 * x = 500 * 100
825x = 50,000
x = 50,000/825
x = 60.6 liters of fuel (61 rounding to the next whole)
x ≅ 61 liters of fuel
<u>The track consumes ≅ 61 liters of fuel every 100 kilometres</u>
Answer:
8x+12
Step-by-step explanation:
Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.
P=2l+2w
P=2(4x-6)+2(12)
P=8x-12+24
P=8x+12
Answer:
its c hope this helps:)
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
For a linear function y = mx + b,
m is the slope and b is the y-intercept at x=0
From the given information, we can immediately see that at x=0 weeks, y = 3 oz, so b = 3
SO we can narrow down the correct answers to A and B where b=3
m can be found by applying the gradient formula m = (y2-y1) / (x2-x)
In this case, if we pick week zero and week 1,
x1=0, y1 = 3, x2=1, y2=6
m = (6-3) / (1-0) = 3/1 = 3
Hence A is the answer.
