2. = 16
3. = x + 10y
4. sry, I don't know this one :(
5. = 14
Hope this helps!!!
oooooooooooooooooooooooooooooooo
Pythagoras Theorem is the way in which you can find the missing length of a right angled triangle.
The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).
Pythagoras is in the form of;
a<em><u /></em>²+b²=c²
However, it can also be written in the form of c²=a²+b²
In order to find the hypotenuse, you will have the length of two sides, for example, these could be 3 and 4.
As 'C' is always the hypotenuse, you have to work out the two other lengths, and you do this by squaring the numbers.
3²=9 and 4²=16.
As you're looking for C, you've got to add these together
9+16=25
As a²+b²=c², this means that the answer for C is the square root of 25.
√25= 5

Answer:
£1,120
Step-by-step explanation:
The computation of the total money earned is given below:
Given that
Ratio of children to adult be 2;3
There is 80 children
each adult cost is £8
And for children it is quarter of adult i.e £8 ÷ 4 = £2
For children there is an earning of
= 80 × £2
= £160
And, for adult it would be
but before that the number of adults be
Let us assume the number of adults be x
After cross multiplication, the number of adult be 120
So the adult earning be
= 120 × £8
= £960
So, the total money made would be
= £960 + £160
= £1,120
Answer:
-(√5)/3
Step-by-step explanation:
The tangent being negative means the sine and cosine have opposite signs. Using the identity ...
cos(o) = ±√(1 -sin(o)^2)
we find ...
cos(o) = -√(1 -(2/3)^2) = -√(5/9)
cos(o) = -(√5)/3
