In 1995, there were 85 rabbits in Central Park. The population increased by 12% each year. How many rabbits
Goryan [66]

Answer:

918

Step-by-step explanation:

Given data

Initila population= 85

Rate = 12%

TIme= 21 years

Let us apply the compounding expression

A=P(1+r)^t

substitute

A= 85(1+0.12)^21

A=85(1.12)^21

A=85*10.80

A= 918

Hence the approximate Rabbit population will be 918

100 POINTS! PLEASE HELP!
Semmy [17]

Apply angle bisector theorem

\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}

\\ \sf\longmapsto 9x=5(2x-1)

\\ \sf\longmapsto 9x=10x-5

\\ \sf\longmapsto 10x-9x=5

\\ \sf\longmapsto x=5

#2

\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}

\\ \sf\longmapsto 4(2.25)=3x

\\ \sf\longmapsto 3x=9

\\ \sf\longmapsto x=3

Hope it helps

The sum of the digits of a two-digit number is 12. The number formed by interchanging the digits is 54 more than the original nu
-BARSIC- [3]
Let X and Y be the digits.
If a two-digit number is written XY, then its value is 10x+y.
When the digits of the number are interchanged, it's YX, and its value is 10y+x.

The sum of the digits is 12.
The number formed by interchaning the digits is 54 more than the original number.

x+y=12 \\
10x+y+54=10y+x \\ \\
x+y=12 \\
10x-x+y-10y=-54 \\ \\
x+y=12 \\
9x-9y=-54 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\div 9 \\ \\
x+y=12 \\
\underline{x-y=-6} \\
x+x=12-6 \\
2x=6 \\
x=\frac{6}{2} \\
x=3 \\ \\
x+y=12 \\
3+y=12 \\
y=12-3 \\
y=9

The digits X and Y are 3 and 9, so the original number is 39.

Two number cubes are rolled and the results are added. What is the probability that the sum is equal to 2?
vodomira [7]

Answer:

Well, assuming that these are cubes labeled 1-6, there is a 1/12 chance of the sum equaling 2, since they would both have to land on 1
