Hundredths: 8.98
Tenths: 9 whole
ones: 9 whole
tens: there is none
The answer is cot² ∅ - csc² ∅ = -1
Referring to Pythagorean identities:
sin² ∅ + cos² ∅ = 1
1+cot² ∅ = csc² ∅
tan² ∅ + 1 = sec² ∅
1+cot² ∅ = csc² ∅
⇒ transposing 1 and csc² ∅ we will have now
cot² ∅ - csc² ∅ = -1
1.625 as a fraction is 1 5/8
15/8 simplified is 1 7/8
if you are using the word "and" to represent multiplication here you go:
first i would change both fractions to a mixed number
13/8×15/8=195/64
simplify
your answer would be 3 3/64
if you are using "and" to represent adding here you go:
1.625 as a fraction is 1 5/8
first i would change 1 5/8 to a mixed number: 13/8
so then add 15/8+13/8=28/8
simplify:
28÷4=7
8÷4=2
7/2=3 1/2
i hope this helped
X= # of adults
y= # of children
1326= 6x + 4y
289= x + y
We are going to do substitution.
x = 289-y
1326= 6(289-y) + 4y
1326= 1734 -6y + 4y
1326= 1734 + -2y
-408= -2y
204 = y
Since we now have a value for y, we should plug that back into the equation we got the x value from to find the actual numerical value of x.
289= x + y
289= x + 204
85= x
In conclusion, 85 adults and 204 adults went to the swimming pool.
