Diameter of a semi circular garden = 18 feet
Radius of the garden :
Thus, the radius of the semi circular fence = 9 feet
We know that :
Which means, the circumference of Mary's semi circular garden :
(pi value = 3.14)
Thus, the circumference of fence needed for the semi circular garden = 28.26 feet
28.26 can be rounded off to 28.30 and 28.30 is the same as 28.3
Thus, Mary's reasoning is correct.
Therefore, Mary's reasoning is correct which means she needs 28.3 feet of fence to surround her garden.
Answer:
7.875 pounds
Step-by-step explanation:
Assuming the beakers are the same size, and each beaker takes in x pounds.
Then for seven beakers we have;
x × 7 = 7x pounds
For the eight beaker;
1/9 × x= 1/9x pounds
Therefore;
7x + 1/9x = 56 pounds
63x + x = 56 ×9
64 x = 504
x = 504/64
= 7.875 pounds
Therefore; one full beaker takes in 7.875 pounds when full
Answer:
True
Step-by-step explanation:
If ab < 0, then ab = negative #.
In order for ab to be a negative #, one of them has to be negative while the other one needs to be positive.
Example:
a = -2, b = 1
ab < 0
(-2)(1) < 0
-2 < 0, TRUE
a < 0
-2 < 0, TRUE
b > 0
1 > 0, TRUE
If I switch a = -2 to 1 and b = 1 to -2, a > 0 and b < 0 is true too.
