Answer:
16cats and 19 birds
Step-by-step explanation:
if we say that x is birds and y is cats we can say that:
4.5x+8.5y=221.5 ( the amount birds and cat both need)
y+x =35 (number of cats and cats)
x=35-y
4.5(35-y) +8.5y= 221.5
157.5-4.5y +8.5y =221.5
4y=64
y= 16
16+x=35
x=19
well first put it as a fraction so 29/9 and then divide which would give u the answer of 3.2 i hoped i helped
The formula for the area of a circle is a = <span>πr², r being the radius.
To tackle this problem, find the area of the square and then subtract the area if the circle:
Area of square = 20 * 20 = 400
Area of circle = </span><span>π(10)² = 100</span><span>π = 314
Area of square - area of circle = 400 - 314 = 86 m²
Hope this helps!

Answer:
Step-by-step explanation:
<u>Lets verify with Pythagorean:</u>
- 17² = 289
- 13² + 14² = 169 + 196 = 365
- 289 < 365
The angle opposite to a greater side is less than 90° and the sum of the squares are close.
It means all three angles<u> are less than 90°</u>.
With this the triangle is <u>acute</u>.
Correct choice is A.
