X intercept: (-4,0)
y intercept: (0,1/2)
x-intercept is when y = 0
-x+8(0)=4
-x+0=4
x=-4
y-intercept is when x = 0
-(0)+8y=4
8y=4
y=4/8=1/2
False, they actually decreased some.
Answer:
2.2.1 Area = 12.6 cm²
2.2.2 Area = 12 cm²
Step-by-step explanation:
<u></u>
<u>2.2.1:</u>
The radius of the big circle is half the length of the square = 2.5 cm
The radius of the small circle is half of 3 cm = 1.5 cm
The area of the shaded portion is = Area of big circle - Area of small circle
π × 2.5²-π × 1.5² = 12.6 cm²
<u>2.2.2</u>
To find length BD (the height of the parallelogram) we need to use the Pythagorean theorem:
BD = √(5²-3²) = 4
Area = base x height = 3x4 = 12 cm²
Answer:
720
Step-by-step explanation:
Heck that's a lot of erasers!!!
36 (erasers per child) x 20 (the number of children) = 720 (number of erasers)
