For the first one, it would be 104-14+=x. I'm not sure about the second one, though. Sorry!
Answer: 40.82
Step-by-step explanation:
Use pythagoras theorem to solve
Root 35 squared + 21 squared = 40.82
Answer:
Step-by-step explanation:
Let r represent speed in the carpool.
We have been given that on the way to work Juan carpools with a fellow co-worker then takes the city bus back home in the evening. The average speed of the 20-mile trip is 5 miles per hour faster in the carpool.
We know that time is equal to distance over speed.
The total distance is 20 mile. Time taken to travel 20 miles using carpool would be 
The speed on the bus is 5 miles greater, so it will be 
. Time taken to travel 20 miles using bus would be 
Total time will be equal to sum of both times that is:
Let us simplify our expression.
Combine numerator:
Therefore, our required expression would be .
In the number 0.125, there is:
0 in the ones place,
1 in the tenths place,
2 in the hundredths place, and
5 in the thousandths place.
We want to round to the hundredths place, which is 2.
To do this we must look to the next digit.
If it's less than 5, we round down.
If it's more than 5, we round up.
The next digit is 5, though! So what do we do then?
Well, we would look to the next digit again<span> and decide from that.</span>
There isn't really a next digit to decide from, though, is there?
<span>In that case, we just round up.
and we get 0.13</span>
Answer:
No it's not compulsory.
Step-by-step explanation:
If the ratio of sides are given then that can also help you find angle. Not only that if the relationship between the perpendicular and base are given then you can find angle
E.g.
if the ratios of the sides is 5:4:3 then you can find the angle
