Answer:
y=−38x−14y is equal to negative 3 eighths x minus 1 fourth is the answer.
Answer:
284.52
Step-by-step explanation:
total area = area of semi circle + area of rectangle
area of semicircle = pi r^2 /2.
= 3.14 * (12/2) ^2 ...divided by 2
= 56.52
area of rectangle = length * breadth
= 19*12
= 228
Answer:
5/8
Step-by-step explanation:
1/4+3/8=5/8
if it is solution point (4, –2) must satisfy both equations
(1) –3x – 2y = –8-->-3*4-2*(-2)=-8
-12+4=-8 then-->-8=-8 ok
(2) y = 2x – 5
-2=2*4-5=3---------->-2 is not 3
the point (4, –2) is not solution of the system of equations
Answer:
7π cm² ≈ 22.0 cm²
Step-by-step explanation:
The shaded area is the difference between the area of Circle B and the areas of Circle C and Circle O. That is, those white areas are subtracted from the area of Circle B to get the shaded area.
The formula for the area of a circle is
A = πr²
Using this, we find ...
Circle B area = π(3 cm)² = 9π cm²
Circle C area = Circle O area = π(1 cm)² = π cm²
Then the shaded area is ...
Shaded Area = Circle B area - Circle C area - Circle O area
= (9π cm²) - (π cm²) - (π cm²)
= 7π cm² ≈ 22 cm²
