The ratio of yellow balloons to blue balloons is 8:12
Then there are 100 balloons. Making the equation, we are able to have:
8X + 12X = 1000
20x = 1000
X = 50.
Yellow balloons = 8x = 8 * 50 = 400 yellow balloons
Blue balloons = 12X = 12 * 50 = 600 blue balloons
So there are 400 yellows balloons.
Answer:
Step-by-step explanation:
Pythagorean Theorem
c^2 = a^2 + b^2
a = 20
b = 15
c = ?
c^2 = 20^2 + 15^2
c^2 = 400 + 225
c^2 = 625 Take the square root of both sides.
√c^2 = √625
c = 25
The third side is 25 cm long.
The circumference would be 40.8 and the area would be 132.7
Answer:
I think it's 4/10 which is 0.4
Step-by-step explanation:
Answer:
(x - 2)² + (y - 3)² = 2²
Step-by-step explanation:
Standard form
(x - h)² + (y - k)² = r²
(h, k) is the center = (2, 3)
r is the radius = 2
(x - 2)² + (y - 3)² = 2²
