Answer:
D) Acceleration is positive and increasing.
Step-by-step explanation:
In formulae, acceleration is defined as the rate of change of velocity per unit time; for example:
where Δ V is the variation of velocity and Δ T is the variation in time.
The graph depicts the velocity of a moving item as a function of time. As we can see ΔV is the increment on the y-axis, while ΔT is the increment on the x axis: therefore, the ratio ΔV/ΔT is the curve's slope. In fact, the slope of the curve in a velocity-time graph corresponds to the object's acceleration. In this graph, we can see that the slope of the curve is growing, which means that the acceleration is positive (since the slope is positive and the velocity is increasing) and increasing (because the slope is increasing).
1:1.67. You divide both sides by 1.8 to reduce the smaller measurement to 1.
1.8/1.8 : 3/1.8 = 1:1.67 and there you go.
2/4,6/12,1/4,3/12 make sure to label with miles cause it will probably be wrong hope this helps!
Its true because 4/3 = 16/12
correspond ing sides are in the same ratio
Answer:
2/3
Step-by-step explanation:
The first place finishers can be divided into two groups: those who went to Ohio State, and those who did not attend Ohio State.
2/5 of the first place finishers went to Ohio State. 1/2 of these were women, which means 1/2 were men. The fraction of first place finishers who went to Ohio State AND were men is:
1/2 (2/5) = 1/5
3/5 of the first place finishers did not attend Ohio State. 2/9 of these were women, which means 7/9 were men. The fraction of first place finishers who did not attend Ohio State AND were men is:
7/9 (3/5) = 7/15
So the fraction of first place finishers who were men is:
1/5 + 7/15
= 3/15 + 7/15
= 10/15
= 2/3
