Answer:
44m
Step-by-step explanation:
A = 
r² = 154
= 22/7 * r² = 154
= r² = 154 * 7/22
= r² = 49
= r = √49
= r = 7m
Perimeter of circle = 2r
= 2 * 22/7 * 7
= 44/7 * 7
= <u>44 m</u>

Answer:
Step-by-step explanation:
240/15 is 16 projects per day
The answer is 25 13/20 square feet.
In order to complete this operation, it is first best to change your mixed numbers into improper fractions.
7 1/8 = 57/8
7 1/5 = 36/5
Now that we have these, we can put them into the triangle formula.
A = 1/2bh
A = (1/2)(57/8)(36/5)
A = 1026/40
You can then simplify this fraction by dividing the top and bottom by a factor of 2.
A = 513/20
Then, because we know 20 goes into 500, 25 times, we can pull that out and be left with a remainder of 13/20.
A = 25 13/20
y = -3x - 2
Since a < 0 we have a decreasing line, so it can be only the first or the last
And if we solve the equation for y = 0 we have
0 = -3x - 2
3x = -2
x = -2/3
So, the last one is the right
