Dave walked to his friend's house at a rate of 4mph and returned back biking at a rate of 10mph. If it took him 18 minutes longer to walk than to bike, what was the total distance of the round trip

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

Answer:

3.62 inches

Step-by-step explanation:

Given :

Ed's string length = 21.72 inches

Georgiana's string length = 1/6 of Ed's string length

To Find :

Georgiana's string length

Solving :

Georgiana's string length = 1/6 of Ed's string length

Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Georgiana's string length = 3.62 inches

Answer:

3.62 inches

Step-by-step explanation:

Step-by-step explanation:

Given that Ed's string length is = 21.72 inches

And that Georgiana's string length is = 1/6 of Ed's string length

We need to find Georgiana's string length

Georgiana's string length = 1/6 of Ed's string length

And Georgiana's string length = 1/6 × 21.72

Georgiana's string length = 21.72/6

Which would bring  us that Georgiana's string length is = 3.62 inches

Answer:

13) x ≥ 50/3

14) see attached graph

15) Yes

Step-by-step explanation:

The equation relating the number of sales and pay is given by

y = 50 + 3x  where x is the number of sales.

Q 13

If you need your pay to be exactly 100 then the above equation translates to 50 + 3x = 100

If you want the sales to be at least 100 then the above equation becomes an inequality 50 + 3x ≥ 100
We can re-write this as x ≥ 50/3

Q 14

See attached graph

x = 50/3 is a vertical line passing intersecting the x axis at x = 50/3(16.67)

All values of x ≥ 16.67 forms the region for the inequality

Q 15

Substitute -3 for n in the equation n(34-n) and check whether it satisfies the inequality

(-3)(34 - (-3)) = (-3)(37) is a negative number. (You don't actually have to calculate it but it works out to -111. ) Therefore it satisfies the inequality
n(n-34) < 111 Answer: YES

Answer:

13. x ≥ 50/3

The meaning of the y-intercept in this situation is that: D. when the cab travels 0 miles, the total fee will be $10.00.

How to calculate the slope of a line?

Mathematically, the slope of a straight line can be calculated by using this formula;

From the table, we have the following parameters:

Points (x, y) = (2, 5) and (13.00, 17.50)

Next, we would calculate the slope as follows:

Slope = (17.50 - 5)/(13.00 - 2)

Slope = 12.50/11.

Slope = 1.14.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

Where:

x and y represents the points.

m represents the slope.

b represents the y-intercept.

Substituting the given parameters into the standard equation, we have;

y - 13.00 = 1.14(x - 2)

y - 13.00 = 1.14x - 2.28

y = 1.14x - 2.28 + 13.00

y = 1.14x + 10.72

Answer: D When the cab travels 0 miles, the total fee will be $10.00.

Answer:

The total area of the back classroom wall is (20ft x 12ft) = 240ft²

The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².

Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.

Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.
