what is the ratio of water around in swamps to the total quantity of fresh water on the surface?

Answers

Answer:

Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.

Step-by-step explanation:

The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11

Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.

What is the volume of the figure below, in cubic centimeters?

2 rectangular prisms. One prism has a length of 16 centimeters, width of 6 centimeters, and height of 2 centimeters. The other prism has a length of 15 centimeters, width of 6 centimeters, and height of 30 centimeters.
A.) 2,700
B.) 2,712
C.) 2,892
D.) 3,072

Answers

The large cube is representing: 16*16*32= 8192cm

And the small cube is representing: 16*6*2= 72cm

length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)

length(mm) × width(mm) × height(mm) ÷ 1000 = cubic centimeters(cm³)

So, answer would be 2,712.

How do you find the radius for a sphere?

10 Points shall be awarded for answering!

Answers

Given diameter: r = d / 2,
Given area: r = √[A / (4 * π)],
Given volume: r = ³√[3 * V / (4 * π)],
Given surface to volume ratio: r = 3 / (A/V).

Some equations based on what is given :)

If given the diameter, divide by 2. For example if the diameter is 16, that would mean the radius would be 8. If the problem doesn’t state the diameter, divide the circumference by pi. So if the circumference was 24, that would make the diameter 7.639437268. From there you divide that by 2 to get the radius. Hope this helps!

A scale model of the front view of Tony’s house is shown. What is the minimum amount of paint needed for two coats?

A. 594 square centimeters
B. 297 square centimeters
C. 216 square centimeters
D. 81 square centimeters

Answers

Answer:

594 square centimeters

The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.

What is the area?

Surface area refers to the area of an open surface or the border of a multi-object, whereas the area of a plane region or plane field refers to the area of a form or planar material.

The shape is a combination of the rectangle and the triangle. Then the area of the shape is calculated as,

A = 1/2 x 18 x 9 + 18 x 12

A = 81 + 216

A = 297 square centimeters

The minimum amount of paint needed for two coats will be 297 square centimeters. Then the correct option is B.

104 legs of horses means 26 horses, since you divide them by 4 to get the number of legs (4) per horse. If there are 36 heads and you subtract the 26 of the horses, you get 10 people heads. There were 26 horses and 10 people

How many solutions are there to this system of equations? On a coordinate plane, 2 lines have equations y = one-fourth (x minus 4) and y = one-fourth x minus 1.
a. one solution
b. no solution
c. infinitely many solutions
d. it cannot be determined without solving

Answers

Answer:

b. no solution

Step-by-step explanation:

y=1/4x-4

y=1/4x-1

This pair of equations has the same slope, meaning that they are parallel lines. Parallel lines never intersect so there is no result of solving this system of equations. Therefore, the correct answer would be b, that this system of equations has no solution.

A carpenter had a board that was 2 yard long. He used 18 inches on a project. How many feet long was the board when he was done?

2 1/2 feet

4 1/2 feet

3 3/4 feet

1 1/4 feet

Answers

Answer:

4 1/2 ft

Step-by-step explanation:

1 yard = 36 inches

2 yards = 2 × 1 yard = 2 × 36 inches = 72 inches

The board started with a length of 72 inches.

He used 18 inches.

72 in. - 18 in. = 54 in.

He has 54 in. left.

Now we convert 54 in. to ft.

1 ft = 12 in.

54 in. × (1 ft)/(12 in.) = 4.5 ft = 4 1/2 ft

What is the approximate equation of this line of best fit in slope-intercept form?

y = −13x + 13 over 10
y = negative 13 over 10x + 13
y = negative 10 over 13x + 13
y = −13x + 10 over 13

Answers

Answer:

Step-by-step explanation:

y = negative 13 over 10x + 13 is the best choice. (0, 13) is the y-intercept. If we begin at (0, 13) and move approximately 10 units to the right, y decreases by 13, so the slope is m = -13/10.

Writing y = negative 13 over 10x + 13 as y = negative 13 over 10 plus 13 would be clearer. We must emphasize that the slope is -13/10 and that this should be enclosed in parentheses: y = (negative 13 over 10)x + 13.

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the proportion be represented as A

Now , the value of A is

Let the distance traveled by the skier in 4 seconds = 72 m

And , let the distance traveled by the skier in 2 1/2 minutes = A

where 2 1/2 minutes = 150 seconds

Now , the proportion is

A / 150 = 72 / 4

Multiply by 150 on both sides , we get

A = ( 150 x 72 ) / 4

On simplifying , we get

A = 2,700 meters

Therefore , the value of A is 2,700 meters

Hence , the distance is 2,700 m

Whats the supplementary angle of 109 degrees.

Answers

Answer:

Answer is 71°

Step-by-step explanation:

Two angles are said to be

supplementary angles if their

sum is 180°.

******************************************

one angle ( x ) = 109°

Let the second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 109°

=> y = 71°

So,

Supplementary angle of 109° should be 71°
