the height can be given as
AB = a sin theta
here a = 4 and theta is 60 so
AB = 4 sin 60 = 4 × √3/2 = 2√3
so area of a parallelogram is
= base × height
= 7 × 2√3 = 14√3
We have to see how many times 130 fits into 1494.23:
![1494.23/130=11.4940....](https://tex.z-dn.net/?f=1494.23%2F130%3D11.4940....)
So now we have to multiply this by the amount of time needed for 130 meters:
11.4940*1=11.4940.
So the answer is 11.4940 minutes.
Three million five hundred thousand or three and a half million
Please show a picture of the expressions then I could help :)
Answer:
B) -3/2
Step-by-step explanation:
If [x/2]=0 then x/2 is a number such that the least integer greater than or equal to x/2 is 0. We can rewrite this as the inequality x/2≤0. Then, the value of x in C, D and E is wrong because they are positive numbers, then x/2 would be a positive number which contradicts this inequality.
Now, 0 is the least integer that satisfies this inequality, therefore we cannot have that x/2≤-1 since -1 is an integer and -1<0. Then x/2>-1. This discards A as wrong, because for x=-2, x/2=-1, contrary to x/2>-1.
Thus B is the right answer. To verify, if x=-3/2, then x/2=-3/4 and we have that -1<-3/4≤0 as required.
