Answer:

B

Step-by-step explanation:

It is $29.35 for each of the tickets that they buy for adults, so to figure out how much it is for all the adult tickets, it would be $29.35 times x. Same for the children tickets except it is times y and the amount of money is different.

A population of insects, in thousands, can be molded using the function (t)= 1.75(0.97)x
Dominik [7]

Question:

A population of insects, in thousands, can be modeled using the function

p(t) = 1.75(0.97)^t, where t is time in months. Which statement best

describes the population of insects?

A. The population is decaying at a rate of 3% each month.

B. The population is decaying at a rate of 25% each month.

C. The population is growing at a rate of 75% each month.

D. The population is growing at a rate of 97% each month.

Answer:

A. The population is decaying at a rate of 3% each month.

Step-by-step explanation:

Given

p(t) = 1.75(0.97)^t

Required

True statement about the function

From the options, we can see that we are to answer the question on the basis of decay and growing rates.

An exponential form is:

y=ab^x

Compare to p(t) = 1.75(0.97)^t

b= 0.97\\

If b > 1, then b = 1 + r r represents growth rate

else, b= 1-r r represents decay rate

Since b < 0.97:

0.97= 1-r

r = 1 - 0.97

r = 0.03

r = 3\%

r = 0.03

Hawaii 0.288% = what fraction
Sindrei [870]

Answer:

36⁄125 or if we are talking about the lowest term it is 9 /3125


Step-by-step explanation:

Step 1: 0.288 = 288⁄1000  

Step 2: Simplify 288⁄1000 = 36⁄125 Percent" or "%" means "out of 100" or "per 100",



<em>Or for the lowest term:</em>

Therefore 0.288% can be written as  

0.288

100

.

Next, we can multiply by  

1

in the form of  

1000

1000

to eliminate the decimal in the numerator:

1000

1000

×

0.288

100

⇒

1000

×

0.288

1000

×

100

⇒

288

100000

.

We can now reduce the fraction as:

288

100000

⇒

32

×

9

32

×

3125

⇒

32

×

3125

⇒
