Answer:
180 in2
Step-by-step explanation:
surface areas of similar solids are proportional to the square of their corresponding sides
area of larger/90 = 10^2/5^2
area of larger = 90(100/25) = 180 in^2
Answer:
y = -5/3x + 4/3z
Step-by-step explanation:
5x + 3y = 4z
3y = -5x + 4z
y = -5/3x + 4/3z
Answer:
46
Step-by-step explanation:
=8-4x+5y
=8+8+30
=46
Answer:
2) 8, 12, -2, 6
3) 8, 11, -3.5, 6.5
Step-by-step explanation:
Equation of the first circle is (x - 1)² + (y + 2)² = 9 and that of the second circle is x² + (y + 2)² = 9
Step-by-step explanation:
- Step 1: Given the center of the first circle (h,k) = (1,-2) and radius, r = 3
Equation of the circle = (x-h)² + (y-k)² = r²
⇒ (x - 1)² + (y + 2)² = 9
- Step 2: Given the center of the first circle (h,k) = (0,-2) and radius, r = 3
⇒ x² + (y + 2)² = 9
