here's the solution : -
if i made 9 costumes and it is 30 % of total costumes, so lets take the total number of costumes as <u>x</u><u> </u>
so, by above statement we get,

=》

=》

so, total number of costumes = 30 costumes.
Answer:
Θ = 124°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n - 5, thus
sum = 180° × 3 = 540°
Sum the given interior angles and equate to 540
2x - 3 + 2x + 7 +3x - 4 + 3x - 4 + 3x - 2 = 540, that is
13x - 6 = 540 ( add 6 to both sides )
13x = 546 ( divide both sides by 13 )
x = 42
Thus
Θ = 3x - 2 = 3(42) - 2 = 126 - 2 = 124°
Answer:
Step-by-step explanation:
Triangle PQR is given to be a right triangle, so the Pythagorean Theorem can be used to determine that PQ is the hypotenuse.
It is given that x^2 + y^2 =z^2 in triangle ABC, so AB = PQ.
The information shows that the triangles are congruent because their three sides are congruent. Therefore, to show that triangle ABC is a right triangle, we can use corresponding parts of the congruent triangles to show that BCA is a right angle.
Answer:
I would say 5x+25 but I don't know the options :/

Answer:
16 birds
8 mammals if you need to know.
Step-by-step explanation:
We can set this system of equations up by plugging the 2m from the second equation into where it says r in the first equation. The reason why we do this is because
The 2m is equal to r, so we can replace the r in the first equation with 2m, since they are equal.
Divide both
We can confirm this because
uh
(I like the enter key lol.)
It's the return key on some keyboards in other countries.
Oh yeah.
We can confirm the values.
If there are 16 birds, there is probably going to be a total of 32 legs.
With 8 mammals, it is something like 8 x 4, which is 32
32 + 32 = 64, which is the total.
