Answer:
0.5 hour
Step-by-step explanation:
Given
Speed of Dina = 10 km/h
Distance = 20 km
So the time Dina taken to complete the track is:
The time taken by Dina is 2 hours. As masha started with dina but she was 4 km of the path left to cycle,
her distance covered in 2 hours was:
So we know the time and distance:
Now,
We have to calculate the time that will be needed by MAsha to complete the track:
As we know the speed and remaining distance
Masha needs 0.5 hour to complete the track ..
Answer:
1164
Step-by-step explanation:
Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.
384 + 600 + 192 = 1164
Answer:
The shortest height is 36 inches
Step-by-step explanation:
Here in this question, we want to know the shortest height with which boxes of 12 inches tall staked will be the same height with which boxes of 18 inches staked beside it
This is a question that has to do with multiples; In other words, we are simply looking for the lowest common multiple of 12 and 18;
The multiples of both are as follows;
12 - 12, 24,36,48,60•••••
18-18,36,54,72••••••
We can see that at the point 36, both have their first multiple match
So we can say that the lowest common multiple of 18 and 12 is 36
$0.81+$9.00=$9.81
Answer: $9.81
We know t<span>o find the total price, first find the amount of sales tax paid by multiplying the sales tax by the original price of the basket of watermelons.
</span><span>9%×$9=<span>?
</span></span>Percent means "out of one hundred," so <span><span><span><span>9% </span></span></span></span> is equivalent to <span>9/100 </span><span>which is also equal to 9 divided by 100.
9 divided by 100 is 0.09
</span>To find the amount of sales tax that must be paid, multiply <span><span>0.09 </span></span><span>by the original price.
So it would be 0.09*$9=$0.81
</span>
<span>To find the final price Tiffany paid, add the sales tax you just found to the original price.
$0.81+$9.00=$9.81
</span>To find the final price Tiffany paid, add the sales tax you just found to the original price.
