Answer:
21
Step-by-step explanation:
the sum of the express of the summation of the notation
To solve we need to use Pythagoras theorem (

)
There are 2 possible lengths for x: hypotenuse or one of the 2 shorter sides.
Hypotenuse:
10^{2} + 21^2 =

100+441=

23.3≈x
Shorter leg:



= 441-100

x≈18.47
25x^2+10x+1
(25x^2+5x)(+5x+1)
5x(5x+1) +1(5x+1)
(5x+1) (5x+1)
X=1/5
Total number of animals at the shelter = 15 + 12 +3 + 5 = 35 animals.
Let the total number of animals be represented by 100%
There are 15 dogs and 12 cats so:
% Number of dogs = 15/35 x 100% = 42.86%
% Number of cats = 12/35 x 100% = 34.28%
Answer:
94
Step-by-step explanation:
Given the addition problem:
58 + 36
We can form a table :
5 _______ 8
+
3 _______ 6
9 4
Hence, (58 + 36) = 94
