Answer:
Well we can make a proportion in this scenario
So 3 cups of soda to 5 cups of punch
And how much soda for 18 punch.
Well we can do this
make “x” the amount of soda
And then make a proportion
3/5 = x/ 18
Now solve
You can cross multiply
54=5x
x=10.8
10.8 soda
To find how many seats in the 80th row, you need to figure out the pattern from the 8th row to the 20th row.
To do this, you can create a table showing possibilities from the 8th to the 20th.
I started with 32 at the 8th and added 2 each time. This was only 56 by the 20th.
Then I added 3, and this got me to 68 by the 20th row.
Then you can work backwards to find how many seats in the 1st row. I got 11.
From here you can create an equation that you could use to solve for the 80th row.
11 + 3(r - 1), where r is the number of rows.
Substitute in 80 for r.
11 + 3(80 - 1)
11 + 237
248 seats
There are 248 seats in the 80th row.
Distance between A and B
= Distance between C and D
= sqrt((4 - 1)^2 + (5 - 2)^2)
= sqrt(3^2 + 3^2)
= sqrt(2 * 3^2)
= sqrt(3^2) * sqrt(2)
= 3sqrt(2)
Distance between B and C
= Distance between A and D
= sqrt((4 - 3)^2 + (5 - 0)^2)
= sqrt(1^2 + 5^2)
= sqrt(26)
Since sqrt(26) is more than 3sqrt(2), the length must be sqrt(26).
Hope this helps you.
Answer:
19/24m-1/3
Step-by-step explanation:
1/6m-(-5/8m+1/3)=1/6m+5/8m-1/3=4/24m+15/24m-1/3=19/24m-1/3
