here are the approximate population of three countries, expressed in scientific notation: panama: 4 x 10^6 ; peru: 3.2 x 10^7 ; thailand: 7 x 10^7. Lin says that more than 20 times as many people live in thailand than in panama. Is this correct
Answer:
No, Lin assumption is wrong
Step-by-step explanation:
Given
Population of panama = 4 x 10^6
population of thailand = 7 x 10^7.
Taking their ratios
thailand/panama = 7x 10^7/4 x 10^6
thailand/panama = 7/4 * 10^7-6}
thailand/panama = 1.75 * 10^1
thailand/panama = 17.5
thailand = 17.5 * panama
Hence the amount of people in thailand is not up to 20times those in panama. Hence Lin assumption is wrong
Using proportions, it is found that the ratio is of 17.5, hence Lin is not correct.
What is a proportion?A proportion is a fraction of a total amount.
In this problem:
Thailand's population is of 7 x 10^7.Panama's population is of 4 x 10^6.The ratio between the populations is given by:
r = 7 x 10^7/(4 x 10^6) = 1.75 x 10^1 = 17.5.
The ratio is of 17.5, hence Lin is not correct.

State the order and type of each transformation of the graph of the function f(x)=1/2[(x+2)^2-9] as compared to the graph of the base function
left 2 units, vertical compression by a factor of 0.5, down 9 units
left 2 units, horizontal stretch by a factor of 2, down 9 units
left 2 units, down 9 units, vertical compression by a factor of 0.5
left 2 units, down 9 units, horizontal stretch by a factor of 2
Answer:
C) left 2 units, down 9 units, vertical compression by a factor of 0.5.
Step-by-step explanation:
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis and if there is a vertical stretch.
Parent Function:
g ( x ) = x 2
Horizontal Shift: Left 2 Units
Down: 9 Units
Vertical Shift: Down 0.5 Units
Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: Compressed

Answer:
390 Millions of bacteria particles by the end of one week.
Step-by-step explanation:
The Bacteria Growth Rate Formula is: ---> N (T) = N (0) * (1 + R) ^tT
N (0) = # of bacteria present during the beginning of the experiment
Variable R= Growth rate
Variable T= Time taken / elapsed.
Substitute the #'s for N (T)
N (0) and T from the given description
We then get the value of variable R.
220 = 20 * (1+R) ^ (24 hrs)
When solving for R, we get R = 0.105074
1 week= (7 x 24 = 168) hrs
We need to plug in the solutions
Therefore
N (168 hours) = 20 * (1+0.105074) ^168
Which is around 390 millions.
So now we know that there will be 390 millions of bacteria particles at the end of 1 week

Oldwick High School has a population of 2345
students. A survey showed that 34% of the student
population would like to have hamburgers as a
daily choice for lunch. Which of the following is
closest to 34% of the student population?
A.340 students
B.800 students
C.1,200 students
D.1600 students
Answer:
B
Step-by-step explanation:
To find your answer, simply multiply 2345 by 0.34. As 34% in decimal form is 0.34 and to find the percentage of a number, you must multiply the number with the percentage. When you do so, you get 797.3 exactly which is closest to 800 students, resulting in B being the answer. PS. Hamburgers every day would be disgusting and boring!!!!

The interior angles of a triangle are inside the triangle and add up to 180 degrees. The exterior angles are angles between any side of the triangle, and the line extended from the side. The sum of an exterior angle and its adjacent interior angle is also 180 degrees.
A game has 28 white balls and 12 red balls in a bag, and you will randomly select one ball from the bag. If
the selected ball is white, you lose $5. And, if the ball is red, you win $10. What is the expected value of
the game?
Answer:
There are 40 balls in the bag. The probability of selecting a white ball is 28/40, simplified to 7/10. The probability of selecting a red ball is 12/40, simplified to 3/10. You are more likely to get a white ball so you will most likely lose $5.

Find the total surface area of the cylinder below. Round to the nearest tenths place.
Answer:
Step-by-step explanation:
r = 0.9 m
h = 3.6 m
Area of two circle faces combined: 2*π(0.9)^2 = 1.62π
Lateral area = circumference*height = 2π(0.9)(3.6) = 6.48π
Surface Area = 1.62π + 6.48π = 8.1π m sq.
A candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create
100 kilograms of a 25% fat-content chocolate. How many kilograms of each kind of chocolate must they
use?
Answer: They must mix
Kilograms of the 10% chocolate and
Kilograms of the 60% chocolate.
Answer:
They must mix 70 kilograms of the 10% chocolate and 30 kilograms of the 60% chocolate.
Step-by-step explanation:
Given that a candy distributor needs to mix a 10% fat-content chocolate with a 60% fat-content chocolate to create 100 kilograms of a 25% fat-content chocolate, to determine how many kilograms of each kind of chocolate must they use, the following calculations must be performed:
10 x 0.5 + 60 x 0.5 = 35
10 x 0.6 + 60 x 0.4 = 30
10 x 0.7 + 60 x 0.3 = 25
100 x 0.7 = 70
Thus, they must mix 70 kilograms of the 10% chocolate and 30 kilograms of the 60% chocolate.
