Step-by-step explanation:

The correct answer is A. Conic projection.

A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.

Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.

Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.

Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.

Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian

2/6 = 0.3 (repeating)

4/6 = 0.6 (repeating)

5/6 = 0.83 (3 repeats)

Answer: 33.3%

Step-by-step explanation:

Since you want numbers less than 3, that would mean you want the sides with #1 and #2. And since there are six sides on the dice, you would put the number of sides you wish over the total number of sides. This would be 2/6 which could be simplified to 1/3 and if you want a decimal answer divide 1/3 to get a repeating decimal then move two decimal places to the right to make it 33.3% (This is rounded to the nearest tenth decimal place)

Answer: 23.04

Step-by-step explanation:

4.0*5.76= 23.04

Answer: The area of the given shape is 9.734 meter square

Step-by-step explanation:

The given shape is a square with 4 sides of equal dimensions "a",

Area of Square = Square of its side "a"

Here, a = Hypotenuse of the inner triangle

Step 1: Get the hypotenuse value of the inner right triangle as the base and height dimensions of the right triangle is given.

Step 2: By using Pythagoras theorem,

Square of the base + Square of the height = square of the Hypotenuse

(2.4)^2 + (2.0)^2 = 9.76

Therefore the value of the hypotenuse = 3.12m

The area of the square = 9.734 meter square.

first we represent the unknowns using variables:

let x = measure of angle 4

let 3x+4 = measure of angle 3 (from the second statement)

then we set-up the equation. since the angles form a linear pair, their sum is equal to 180 degrees. therefore,

x + 3x + 4 = 180

4x + 4 = 180

4x = 176

x = 44 degrees (measure of angle 4)

3x + 4 = 136 degrees (measure of angle 3)

The measure of the angles ∠C and ∠D are 144 degrees and 36 degrees if ∠C and ∠D are a linear pair. ∠C is four times larger than ∠D.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

∠C and ∠D are linear pairs.

It means the sum of the angles ∠C and ∠D will be 180 degrees

∠C + ∠D = 180

∠C = 4∠D

After solving the pair of linear equation in two variables by substitution method:

4∠D + ∠D = 180

5∠D = 180

∠D = 36 degrees

∠C  = 4(36) = 144 degrees

Thus, the measure of the angles ∠C and ∠D are 144 degrees and 36 degrees if ∠C and ∠D are a linear pair. ∠C is four times larger than ∠D.

Answer:

[S / (2πr)] - r = h

Step-by-step explanation:

You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.

S = 2πr(r + h)

Divide by 2πr to try to isolate h

S / (2πr) = r + h

Subtract r from both sides to get h by itself

[S / (2πr)] - r = h

That is your final answer.

\(\\ \rm\Rrightarrow S=2\pir(r+h)\)

\(\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}\)

\(\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r\)

\(\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}\)

The percent decrease in the number of times Hector was scared of the diving board is 37%.

percentage, a relative value indicating hundredth parts of any quantity.

Given that,

Yesterday at the pool Hector got scared of the diving board= 198 times

Today at the pool he only got scared = 124 times

Thus he decreases his fear from yesterday to today is

198-124=74.

So now we need to calculate how much is 74 in 198.

Percentage can be calculated by dividing the value by the total value, and multiplying with 100

74/198×100

=37.37%

After rounding to the nearest percent we get=37%.
