Answer:
382 children and
312 adults swam
Step-by-step explanation:
Let the number of children be x
And let the number of adult be y
Hence on a hot summer day
x +y = 694 - - - - - - - 1
x= 694-y
Also the daily prices are $ 1.25 for children and $ 2.50 for adults
1.25x + 2.50y= 1257.50-------2
Let us substitute x= 694-y in equation 2
1.25(694-y) + 2.50y =1257.50
867.5-1.25y +2.50y = 1257.50
-1.25y+2.50y= 1257.58-867.5
1.25y= 390
y= 398/1.25
y= 312
Substitute y= 312 in equation 1 to find x
x + 312= 694
x= 694-312
x= 382
Hence 382 children and
312 adults swam
First we convert the m to km by dividing the number by 1000. 1000m = 1 km.
150,000,000,000 / 1000 = 150,000,000 km
Now we divide 150,000,000/11,000,000 = 13.6363636364 au.

Answer:
y ≈ 12.3
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to help you remember the relationship between trig functions and side of a right triangle. In particular, when the adjacent side and hypotenuse are involved, the desired relation is ...
Cos = Adjacent/Hypotenuse
cos(35°) = y/15
y = 15·cos(35°)
y ≈ 12.3
