Answer: discarding A₀ = 0° ( because this is not a rotation) You have 6 angles for symmetrical rotation, so the order of rotational symmetry is is 6.
Answer:
10
Step-by-step explanation:
The vertical scale gives us the frequency or the number of pets under each category . From the diagram;
The number of Dogs is 11 while there is only 1 horse
The difference between this numbers will be the solution to the question posed;
11 - 1 = 10
Therefore, 10 more dogs are pets than horses
Answer:
Yes, the right angle is angle B
Step-by-step explanation:
we have
Plot the vertices
see the attached figure
we know that
If triangle ABC is a right triangle
then
Applying the Pythagoras Theorem
the formula to calculate the distance between two points is equal to
<em>Find the distance AB</em>
substitute in the formula
<em>Find the distance BC</em>
substitute in the formula
<em>Find the distance AC</em>
substitute in the formula
Verify the Pythagoras theorem
---> is true
therefore
Is a right triangle and the right angle is B
Answer:
C
Step-by-step explanation:
write an equation for the costs:
if x is the number of sodas
and y is the number of waters
2.75x + 2y <= 15
(<= is less than or equal to)
if we substitute 3 for y
we get 2.75x + 2(3) <= 15
2.75x + 6 <= 15
2.75x <= 9
9 / 2.75 = 3.2727
however, you cannot buy part of a soda
so, round to 3
you also cannot buy negative sodas
so, the answer is C
Answer:
31
Step-by-step explanation:
16(3) - 3(-1) + 5(-4)
48 + 3 - 20
