Answer:
13/14 > 25/28
Step-by-step explanation:
30%
1/5 is 0.2, or 20%. So 50%+20% = 70%. The remainder is 30%
Answer:
Since we have two semi-circles we can say that we have a full circle. using the circle area formula we can say that
3.14*2^2 = 12.56 cm
Using the rectangle area formula we can say that
19*4 = 76 cm
Adding them both together is
12.56 + 76 = 88.56 cm
So the bookmark has an area of 88.56cm^2
If she is running on that track she will have ran
4022.5
y = x² - 4x + 8
4x + y = 12
4x + y = 12
4x + (x² - 4x + 8) = 12
x² + 4x - 4x + 8 = 12
x² + 8 = 12
- 8 - 8
x² = 4
x = ±2
4x + y = 12
4(2) + y = 12
8 + y = 12
- 8 - 8
y = 4
4x + y = 12
4(-2) + y = 12
-8 + y = 12
+ 8 + 8
y = 20
(x, y) = (2, 4) and (-2, 20)
