Water makes up about 71% of the Earth's surface, while the other 29% consists of continents and islands. 96% of all Earth's water is contained within the oceans as salt water, while the remaining 4% is fresh water located in lakes, rivers, glaciers, and the polar ice caps.

a. If the total volume of the Earth is 1,386,000,000 km3, the volume of salt water is ? km3.

b. If the total volume of the Earth is 1,386,000,000km3, the volume of fresh water is ? km3.

Answer:

\(380 \text{ m}^2\)

Step-by-step explanation:

To find the surface area of the trapezoidal pyramid, we can use the formula:

\(SA = 2(b) + (p \cdot d)\),

where \(b\) is the area of the base, \(p\) is the perimeter of the base, and \(d\) is the prism's depth.

First, we should find the area of the base using the area of a trapezoid formula.

\(A_\text{trap} = \dfrac{b_1 + b_2}{2} \cdot h\)

\(b = \dfrac{15 + 5}{2} \cdot 7\)

\(b = 10 \cdot 7\)

\(b = 70 \text{ m}^2\)

Now, we can plug the given dimensions along with the base area into the surface area formula.

\(SA = 2(b) + (p \cdot d)\)

\(SA = 2(70) + ([15 + 10 + 5 + 10] \cdot 6)\)

\(SA = 140 + (40 \cdot 6)\)

\(SA = 140 + 240\)

\(\boxed{SA = 380 \text{ m}^2}\)

Answer:

c) 78 plants

Step-by-step explanation:

The total required is,

→ x = 143/11

→ [ x = 13 ]

Then number grew into plants,

→ 6 × x

→ 6 × 13

→ 78 plants

Hence, the option (c) is correct.

Answer: 78

Step-by-step explanation: 143 /11=13x6=78

Answer:

15.94490514

Step-by-step explanation:

First, work out the average, or arithmetic mean, of the numbers:

Count: 5(How many numbers)

Sum: 357(All the numbers added up)

Mean: 71.4(Arithmetic mean = Sum / Count)

Then, take each number, subtract the mean and square the result:

Differences:

4.6, -26.4, -7.4, 8.6, 20.6

(Every Number minus Mean)

Differences^2:

21.16, 696.96, 54.76, 73.96, 424.36

(Square of each difference)

Now calculate the Variance:

Sum of Differences2:1271.2(Add up the Squared Differences)

Variance:254.24(Sum of Differences2 / Count)

Lastly, take the square root of the Variance:

Standard Deviation:15.94490514 (The square root of the Variance)

Answer:

15 sides

Step-by-step explanation:

As we know the full angles of a polygon is 360°

And

Each side has angle 24°

So,

n = 360/24

n = 15 sides

I hope my answer helps you.

the sum of all interior angles in a polygon is

this polygon has hmmm 6 sides, namely a HEXAgon, so the total amount for all its interior angles in degrees is 180( 6 - 2) = 720°.

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

I hope this helps!

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.

Answer:

"A value that is substituted in for the variable in a function in order to generate an output value" is gonna be known as an input.

"A group of two numbers written in the form (x, y) where the x value represents a horizontal position and the y value represents a vertical position" is known as an ordered pair.

"A value generated by a function when an input value is substituted into the function and evaluated" is known as an output.

Answer:

Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Hope this helps!

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

z = 56°

Step-by-step explanation:

Angle on a straight line add up to 180°

Therefore, 124 + z = 180

⇒ z = 180 - 124 = 56°

Linear pair angles are supplementary

\(\\ \rm\hookrightarrow z+124=180\)

\(\\ \rm\hookrightarrow z=180-124\)

\(\\ \rm\hookrightarrow z=56\)

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

7+5=12

12 is more than 11 which makes it a triangle.

When the 2 smallest measures are larger than the 3rd measure then it is a triangle.

Answer:

10r+5

Step-by-step explanation:

Below, we'll examine definitions of "coefficients" and "constants" in the context of the correct answer "10r+5"

Coefficients

Coefficients are numbers that are multiplied to letters.  When a number is multiplied to a letter, the multiplication symbol is often not explicitly written in.

In this case, the 10r means there are ten r's, similar to how if one had ten cars, one could say 10 cars (without needing to write in a multiplication symbol).

Constants

Constants are numbers that are not multiplied to a number.  They are a number on their own that may (or may not) be connected to something else by addition (note: it may also be connected to something by "subtraction", but the subtraction should instead be thought of as "plus a negative").

In this case, the 5 is by itself (not multiplied to anything), and is added to other things.

Ruling out the other answers

In the first choice, 10-5, there is subtraction, so we envision it as 10+(-5).  the neither the 10 nor the -5 are multiplied to anything, so they are both constants.

In the second choice, the 10 is not multiplied to anything, but the 5 is multiplied to "r".  So, the 10 is a constant, and the 5 is a coefficient, but that is not what was requested.

In the last choice, again, the 10 and the 5 are not multiplied to anything, so they are both constants.
