➷ Use this formula:
Area of circle = 
However, as we are using 3.14 for 'pi', we can write it like this:
Area = 
'r' is the radius which is 12ft
Substitute this value into the equation:
Area = 
Solve:
Area = 452.16
Multiply this value by 0.75 to get the answer:
452.16 x 0.75 = 339.12
339.12 square feet is being watered

Answer:
There are 24 1/6-banana sections in 4 bananas.
Step-by-step explanation:
Here we need to divide 4 bananas into 1/6 banana sections. Dividing 4 bananas by 1/6 is equivalent to multiplying 4 bananas by 6/1:
(4)(6)
-------- = 24
1
There are 24 1/6-banana sections in 4 bananas.
Answer:
1) 5 2) the first one
Step-by-step explanation:
1)
since the first time multiplying 8 to get a two digit number ending in zero is forty, i multiplied both by 5
2) 8 times 12= 96+20=116
10 times 12=120 (already too much)+10=130
i hope this helps u
pls give a brainliest (i only need one more!) and a thx
Answer:
(-138) is the answer.
Step-by-step explanation:
Perfect square numbers between 15 and 25 inclusive are 16 and 25.
Sum of perfect square numbers 16 and 25 = 16 + 25 = 41
Sum of the remaining numbers between 15 and 25 inclusive means sum of the numbers from 17 to 24 plus 15.
Since sum of an arithmetic progression is defined by the expression
![S_{n}=\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=S_%7Bn%7D%3D%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Where n = number of terms
a = first term of the sequence
d = common difference
![S_{8}=\frac{8}{2} [2\times 17+(8-1)\times 1]](https://tex.z-dn.net/?f=S_%7B8%7D%3D%5Cfrac%7B8%7D%7B2%7D%20%5B2%5Ctimes%2017%2B%288-1%29%5Ctimes%201%5D)
= 4(34 + 7)
= 164
Sum of 15 + 
= 15 + 164 = 179
Now the difference between 41 and sum of perfect squares between 15 and 25 inclusive = 
= -138
Therefore, answer is (-138).
Answer:
4x² -20x +61
Step-by-step explanation:
the quadratic equation can be written as (x-root1)(x-root2)
(x-(5/2) -3i) (x-(5/2)+3i), distribute
x² -(5/2)x +3xi -(5/2)x + 25/4 -(15/2)i -3xi +(15/2)i -9i², simplify
x² -(5/2)x -(5/2)x + 25/4 -9i², use the fact that i² =(√-1)² = -1 and substitute i²
x² -(5/2)x -(5/2)x + 25/4 +9, combine like terms and rewrite 9 as 36/4
x² -(10/2)x +25/4 + 36/4, combine like terms and simplify
x² -5x +61/4 is the quadratic expression yet it does not have integer coefficients so multiply by 4 to have all coefficients integers
4x² -20x +61
