Answer:
19 seconds.
Step-by-step explanation:
Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:
1 PM = 13:00
13 - 7 = 6
228/6 = 38
38/2 = 19
Thus, every half hour the clock is delayed 19 seconds.
Answer:
y+3= -6(x+9) is the answer
Step-by-step explanation:
Answer:
It’s b.
Step-by-step explanation:
To get the slope of the line, you need to points. Two points you already have are (0,0) and (-5,6). So all you need to do is plug those points into slope equation (y1-y2 over x1-x2) 0-6 over 0+5 equals -6/5. The slope equals -6/5, and when you plug it into y=mx+b it equals y=-6/5x. Which is b.
So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.
3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.
3.54/3=1.18
10^7/10^8=1/10
Now we just multiply our answers together because we separated them before we divided.
1.18*1/10=.118
So the answer is .118 seconds
Answer:
17
Step-by-step explanation:
Let the amount of roses in the second yard be x. This means that the number of roses in the first yard would be x-10. If nine roses were transplanted from the second yard to the first one, the number of roses in the second yard would be x-9 and the number of roses in the first yard would be x-1. It is stated that now, there would be 2 times more roses in the first yard than the second one, which means that 2(x-9) = x-1, which simplifies to 2x-18 = x-1. Subtract both sides by x, and we get x-18 = -1. Add 18 to both sides, and we get x = 17, therefore, there are 17 roses in the second yard.
