Answer:
A. the area of the large pond is 16 times the area of the small pond
Step-by-step explanation:
let's say 4 is the radius of the small circle, which means the area is 50.26548
if the large circle is 4 times the small circle, that means it's radius is 16 which means the area is 804.24772
so if you divide the big circle area by the small circle area:
804.24772/50.26548
it gives you 16.00000079577 which is rounded to 16
therefore, the bigger circle is 16 times bigger than the smaller circle
2(3t - 1) - 5(t - 1)
2(3t) - 2(1) - 5(t) + 5(1)
6t - 2 - 5t + 5
6t - 5t - 2 + 5
t + 3
Answer:
When simplified its 8x^9 y^12
Step-by-step explanation:
Answer: x = 7
Step-by-step explanation:
do opposites to both sides. what is the opposite of -5? it would be plus 5.
add 5 to both sides
3x = 21
now what is the opposite of 3 times x? 3 divided by.
divide 3 to both sides
x = 7
Answer:

Step-by-step explanation:
Let be "x" the lenght of the longest side, "y" the lenght of the middle side and "z" the lenght of the shortest side.
The perimeter is:
[Equation 1]
We know that the longest side is 10 less than twice the middle side length. This can be expressed as:
[Equation 2]
And the middle side length is three less than three times the shortest side length. This is:
[Equation 3]
The steps are:
- Solve for "z" from the third equation:

[Equation 4]
- Substitute [Equation 4] into [Equation 1]
- Substitute [Equation 2] into [Equation 1]
Then:

- Solve for "y":

- Substitute this value into [Equation 2] and into [Equation 4]:
