Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish
(-1,4) and (3 1/64)
I took the test like 5 minutes ago.
I hope this helps!
Ross calculated the missing side length of the triangle F.
Solution:
Let us first define the Pythagoras theorem.
Pythagoras theorem:
<em>In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.</em>
So, it is clearly define that Pythagoras theorem is applied for right triangles only.
Right angle is indicated by the symbol "L".
In the given triangles,
E is acute angled triangle.
G is obtuse angled triangle.
H is acute angled triangle.
F is right angled triangle.
Therefore, Pythagoras theorem can be applied only for triangle F.
So Ross calculated the missing side length of the triangle F.
Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
there are 6 sides to a hexagon
360/6 = 60 degrees
so it will map onto itself at 60, 120, 180, 240, 300 & 360
there are 6 different angles
