Answer:
Step-by-step explanation:
-3x + 4y = -18
8x - 4y = 28
5x = 10
x = 2
4 - y = 7
-y = 3
y = -3
(2, -3)
Answer:
It is 1,965.74 square feet
Step-by-step explanation:
the area of the circle is πr^2 so if you substitute the variables with the numbers you get, π29^2=841π=841*3.14=2640.74
the area of the triangular flowerbed is 1/2bh=1/2*27*50=675
if you want to find the grass area you would need to subtract the triangular area from the circle, which is 2640.74-675=1965.74 square feet
Answer:
Perimeter of square = 80 feet Circumference of circle = 80 feet
How many square feet greater is the area of one of the flower beds than the other? (use 3.14 for pi)
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2
largest value = 50 ⇒ 50² = 2500
14² + 48² = 196 + 2304 = 2500
Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet
These would all be correct!
