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

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.

A proportion is a fraction of a total amount.

In this problem:

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.

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!!!!

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.

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.

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.

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
