What is a example of a composite figure in your home or community? How would you decompose it to find the area? Can you think of
ipn [44]
Answer: An L-shaped room in your house

Imagine any room in your house that is not just a single rectangle, square or other shape. This would be an example of a composite shape. It simply means that it is made up of more than one shape.

For example, if you had a living room in the shape of an L. This would be a composite shape because you would have to put 2 rectangles together to make the shape.

: A new bear population that begins with 150 bears in 2000 decreases at a rate of 20% per year.
d1i1m1o1n [39]

Answer:

2 bears in 2020.

Step-by-step explanation:

We have been given that a new bear population that begins with 150 bears in 2000 decreases at a rate of 20% per year.

We will use exponential decay formula to solve our given problem as:

y=a\cdot (1-r)^x, where,

y = Final quantity,

a = Initial value,

r = Decay rate in decimal form,

x = Time

20\%=\frac{20}{100}=0.20    

Upon substituting our given values in above formula, we will get:

y=150(1-0.20)^x

y=150(0.80)^x, where x corresponds to year 2000.

To find the population in 2020, we will substitute x=20 in our equation as:

y=150(0.80)^{20}

y=150(0.011529215046)

y=1.7293822569    

y\approx 2

Therefore, 2 bears are there predicted to be in 2020.

Since population is decreasing so population is best described as exponential decay.

Nikki had 70% of her savings left in her bank account. If she has $230 in her bank account, how much did she start with?
Alex

Answer:

$299

Step-by-step explanation:

Given that 70% is $230 you can divide this by 7 to get 10%.

10% is 23. The remaining percentage we need is 30.

Soo 10% x 3 = 30%. (23x3)

23 x 3 = 69.

69 + 230 = $299
