The odd numbers between 1 and 7 are: 3 and 5. If we add all those numbers including 1 and 7, we have: 1 + 3 + 5 + 7 = 16.
Answer:
As i understand it:
The total park is 2.4 ha
10% of that is paths and 15% of that is a lake.
So a 10% + 15% = 25% is taken.
So we have left a 75% of the park, this is:
Left = (75%/100%)2.4 ha = 0.75*2.4ha = 1.8 ha.
Now we also need to subtract the are of the tennis court.
The tennis court occupies a rectangular plot of 60m by 50m (you actually wrote cm here, but i guess it was a mistake, we can not have a tennis court of 60cm by 50cm)
So the area of the tennis court is:
A = 60m*50m = 3,000 m^2
But we want to write it in ha
We know that:
1ha = 10,000m^2
then 3,000m^2 = (3,000/10,000) ha = 0.3 ha
Then the left area is:
L = 1.8 ha - 0.3ha = 1.5 ha.
Answer:
19
Step-by-step explanation:
Here we have to find out number of people attended the party. we are given with the number of the handshakes in the party .
We are going to use the following formula to determine the number of guests
Nos. of handshakes
Here we have H = 171
Hence our equation becomes
now we solve it by splitting the middle term method
Now we have to find the factors of 342 whose difference to 1. The factors are 19 and 18 in this case. hence we slit our middle term like this
Hence
either
(x+18)=0 or (x-19) =0 Thus
x=-18 which is not possible as no of people can not be less than 0
x=19 which will our answer
Answer:
oh i dont know :0
