If only one-quarter of the earth's surface is not covered by bodies of water, and only one half of that exposed land area is inhabitable for humans (because of poles, deserts, etc.), what fraction of the earth's surface can humans live on?

Answers

Answer 1

Answer:

So on the one hand, you could say from these results that 10% of Earth is inhabited by humans. Or you could take a more glass half-empty view and say that 90% of Earth is covered by humans – either populated or connected with an ever-expanding network of roads, train tracks, highways, farms and industrial land.

Jasim has invested 600 dinars in a business at the rate of 4 % for 3 years. Find his

i- simple interst ?


ii- total amount after 3 years ​

Answers

Answer:

1) Simple interest is 72 dinars

2) Total amount after 3 years is 672 dinars.

Step-by-step explanation:

Principal Amount P = 600 dinars

Interest Rate= 4% = 0.04

Time = 3 years

i) Simple Interest

The formula used to calculate interest is [tex]I=P\times r \times t[/tex]

Putting values and finding interest

[tex]I=P\times r \times t\\I=600\times 0.04 \times 3\\I=72[/tex]

So, simple interest is 72 dinars

ii) Total amount after 3 years ​

The formula to calculate total amount is: [tex]A=P(1+rt)[/tex]

Putting values and finding future amount A

[tex]A=P(1+rt)\\A=600(1+(0.04*3))\\A=600(1+0.12)\\A=600(1.12)\\A=672[/tex]

So, Total amount after 3 years is 672 dinars.

Mr. Stack and Coach Pugh are racing down the highway. Coach Pugh is going five miles more an hour than twice Mr. Stack's speed. If Coach Pugh is going one hundred and five miles and hour, how fast is Mr. Stack going?

Answers

Answer:

50

Step-by-step explanation:

2(Mr stack's speed) = Coach Pugh's speed - 5mph

Mr stack's speed = (105mph - 5mph)/2

56 mm = 5.6 cm since there are 10 mm in a cm, so we divide by 10 to go from mm to cm.

Since the diameter is 5.6 cm, this means 12 such cans lead to 12*5.6 = 67.2 cm of length needed to house 12 cans along this row.

Similarly, if we had 6 cans along each column, then 6*5.6 = 33.6 cm is needed for this

The diagram below shows what I mean. This diagram is a top-down view of the box. In other words, it's a birds-eye view.

The last dimension we need to take care of is the height of the box. That would be 2*5.6 = 11.2 cm since there are 2 cans along the height

Therefore, the smallest box possible has dimensions of 67.2 cm by 33.6 cm by 11.2 cm

You could have bigger boxes of course, though you'll need to place cushions inside so the cans don't rattle around. The smallest box dimensions listed above are ideal to avoid wasting too much cushion material (you'll still may need some form of cushion though just not as much).

Answer:

Step-by-step explanation:

The right triangle has the hypotenuse = 18

Let 'Ф' be the missing angle

we know that

cos Ф = adjacent/hypotenuse

Here,

The adjacent to Ф = 13The hypotenuse = 18

so

cos Ф = adjacent/hypotenuse

[tex]cos\:\theta \:=\frac{13}{18}[/tex]

[tex]\theta \:=\cos ^{-1}\left(\frac{13}{18}\right)[/tex]

The difference between two same side interior angles of two parallel lines is 35 degrees. Find the measures of these two angles.

Answers

Answer:

  107.5° and 72.5°

Step-by-step explanation:

  x + y = 180          same side interior angles of two parallel lines add up to 180

  x - y = 35            

___________

     2x = 215                           add above two equations

       x = 107.5°                       divide by 2 to isolate x

Substitution to find y:

  x + y = 180

  107.5 + y = 180

              y = 72.5°

The measure of these two angles is 107.5° and 72.5°.

Given that,

The difference between two same-side interior angles of two parallel lines is 35 degrees.We need to find the measure of the two angles. Here we assume the two angles be x and y.

Based on the above information, the calculation is as follows:

x + y = 180          

And,

x - y = 35            

So, after solving it, it comes

2x = 215                            

x = 107.5°                  

So, y = 180 - 107.50 = 72.5

Therefore we can conclude that the measure of these two angles is 107.5° and 72.5°.

The population of ages at inauguration of all U.S. Presidents who had professions in the military is​ 62, 46,​ 68, 64, 57. Why does it not make sense to construct a histogram for this data​ set? Choose the correct answer below.
A. There must be an even number of data values in the data set to create a histogram.
B. This data set would yield a histogram that is not​ bell-shaped.
C. Adequate class boundaries for a histogram cannot be found with this data set.
D. With a data set that is so​ small, the true nature of the distribution cannot be seen with a histogram.

Answers

Answer:

The correct option is D.

Step-by-step explanation:

A histogram is a bar chart wherein the horizontal scale signifies class interval (or classes of data values) and the vertical scale signifies frequencies or percentages. The altitudes of the columns relate to the frequency values, and the columns are drawn together without breaks.

The histogram has the following properties:

• Shows the shape of distribution

• Shows the location of center

• Shows the spread of data

• Helps in identifying outliers

Since the sample collected is so small, the true nature of the distribution cannot be seen with a histogram.

Thus, the correct option is D.
