How long will it take for a certain population of fish to triple if the relative growth rate is 45% per year?

Answers

Answer:

n = 3 Year (Approx)

Step-by-step explanation:

Given:

Growth rate (r) = 45% = 0.45

Find:

Number of year for 3 times of population (n)

Computation:

Assume;

Current population = P

So,

New population = 3P

A = p(1+r)ⁿ

3P = P(1+0.45)ⁿ

3 = (1.45)ⁿ

n = 2.96 year

n = 3 Year (Approx)

Point O is a centroid of the triangle LMN. If OM=38 cm, what is MP?
a.) 114 cm
b.) 19 cm
c.) 57 cm
d.) 25.5 cm

Answers

9514 1404 393

Answer:

  c.)  57 cm

Step-by-step explanation:

The centroid divides the median into parts with a 2:1 ratio.

  OM : OP = 2 : 1

  OM : MP = 2 : (2+1) = 2 : 3

As a fraction with MP on top, this is ...

  MP/OM = 3/2

  MP = (3/2)OM = 3/2×(38 cm)

  MP = 57 cm

__

Comment on the answer choices

Often, you can eliminate a number of the choices in a multiple-choice question just by testing whether they are reasonable. Here, the longer part of a line segment has length 38, so the whole segment will not be shorter than that. The choices 19 and 25.5 make no sense.

The remaining choices are 114 cm and 57 cm. The former is 3 times the length of the given segment, which the drawing tells us is unreasonable.

The only reasonable choice offered is 57 cm.

Answers

Answer:

4 Bales Of Hay

Step-by-step explanation:

First you need to split the total into thirds. To do this you divide 6 by 3

6/3 = 2

Then since there are two thirds, you multiply 2 by 2

2*2 = 4

So the final answer is 4

Number 13 Find the measures of angles 1, 2, and 3.

Answers

Answer:

1. 37

2. 26

3. 26

Step-by-step explanation:

Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.

Tayler's mom purchased a savings bond for Tyler. One year after it was purchased, the value of the savings bond was $156. If the value of the savings bond increases by 4% after one year, what was the value of the bond when Tyler's mom purchased it? Explain or show your reasoning.

Answers

Answer: The value of the bond when Tyler's mom purchased it = $150

Step-by-step explanation:

Let x= Purchasing price of the bond.

Given: Rate of increase in its value = 4% = 0.04

Value of bond after one year = x+ 4% of x

= x+0.04x

= 1.04x

One year after it was purchased, the value of the savings bond was $156.

[tex]\Rightarrow\ 1.04x = 156\\\\\Rightarrow\ x=\dfrac{156}{1.04}\\\\\Rightarrow\ x=150[/tex]

Hence, the value of the bond when Tyler's mom purchased it = $150

A couch was originally priced $500 dollars and on sale for 70% off what is the price for after the discount

Answers

Answer: the answer would be $150

Step-by-step explanation:

Answer:$150.00

Step-by-step explanation:

If you think about a item going down by 70%, it means that you are paying only 30% of the total price.

100%-70%=30%

So 30% of $500 is what you are paying.

30%=30/100=0.3

So you multiply 0.3x500

Which is equal to 150

Exercise 1 Read the passage. Based on what you already know, underline the verbs.The Marshmallow ExperimentImagine that you are seven years old. You are participating in an experiment. A researcher greets you and shows you into a small room. In the room there is a marshmallow. The marshmallow is for you, but here is the interesting part: The researcher tells you that he is going to leave you alone in the room for a while. You can eat the marshmallow right away, or you can wait until he gets back. If you wait until he gets back, you will get a second marshmallow.What do you do? Do you eat the marshmallow right away?An experiment like this, known informally as the marshmallow experiment, was conducted decades ago at Stanford University. It turned out that some children ate the marshmallow right away, while others were able to wait. In other words, some sought instant self-gratification, and some delayed it.Years later, the researchers followed up on the participants. They found that the children who delayed self-gratification were in general more successful than those who ate the marshmallow right away. By a variety of measures, including SAT scores, they appeared to be more competent.Common sense tells us that the ability to delay self-gratification is a mark of maturity. The marshmallow experiment provides evidence that it may also correlate with success in life.Notes:- Many of these verb phrases consist of an auxiliary verb and a main verb.
