Answer:
4.5 hours
Step-by-step explanation:
To answer this, we shall be using a diagrammatic representation.
Now, let the time taken for them to be 54 miles apart be x hours
Mathematically, distance = speed * time
For the north bound boat, it would be 4 * x miles away = 4x miles away from the starting point
For the south bound boat, it would have travelled a distance of 8 * x = 8x miles
Now the distance between both is 54 miles ; this means that by adding the distance traveled by both, we shall have a total length of 54 ;
Thus mathematically;
4x + 8x = 54
12x = 54
x = 54/12 = 4.5 hours
Answer:
60°
Step-by-step explanation:
Here we are given that the number of convertibles cars. Total number of cars owned by the dealers is 90. We have to draw the pie graph for above ratio. The pie chart is a circular statistical graph , where the different portion in form of sectors on the circle showing the amount of different entities.
The angle covered by an entity is in the same proportion as its number is in ration to the total number of all the entities.
Hence
Hence we will represent 60 degrees in order to represent 15 cars in our chart.
X-20 = Y+20........ X-Y = 20+20........
X-Y = 40
AND
2Y-44=X+22............. Y-X= 44+22
Y-X=66
NOW, LET'S FIND X AND Y FROM THESE TWO EQUATIONS....
X-Y =40
Y-X= 66
IF WE COLLECT ....... 2Y = 106 AND Y = 53
THEN, USE Y IN ANY EQUATIONS FOR FINDING X
X-53 = 40 ..... X= 53+40 .......... X= 93
X= 93
Y=53
