a.) The value of pulses exported by US in billion would be=30 billion.

b.) The ratio of wheat export of UK to maize export of IND would be= 6:5

For question a.)

To calculate the pulses, the following steps should be taken as follows:

From the bar chart, the value of pulses in billions = 30 billions.

For question b.)

The ratio of wheat export at UK and maize export at IND would be calculated as follows:

The quantity of wheat export at UK = 24

The quantity of maize export at IND = 20

Therefore, the ratio of wheat to maize = 24:20= 6:5

The equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.

To calculate the equivalent ratio of 1.25 : 3.75 : 7.5, we need to find a common multiplier that can be applied to all the numbers in the ratio to make them whole numbers. In this case, the common multiplier is 4 because it can be multiplied to each number to eliminate the decimals.

By multiplying each number in the ratio by 4, we get:

1.25 * 4 = 5

3.75 * 4 = 15

7.5 * 4 = 30

So the equivalent ratio of 1.25 : 3.75 : 7.5 is 5 : 15 : 30.

This means that the relative sizes or quantities represented by the original ratio are maintained in the equivalent ratio. For example, if we had 1.25 units of something, it would be equivalent to 5 units in the new ratio, and if we had 7.5 units, it would be equivalent to 30 units in the new ratio.

V = 19.739 is  the volume of the solid below the surface of revolution and above the xy-plane.

What is the solid's volume?

The amount of space that a solid occupies is expressed in terms of its volume. It is calculated using the quantity of unit cubes required to completely fill the solid.

                 We have 30 unit cubes in the solid after counting the unit cubes, hence the volume is 2 units. 3 units 30 cubic units from 5 units.

Given Curve

z = sin(y) , (0 ≤ Y ≤ π)

It's on the y-z plane to see the volume of revolution.

It is the upper portion of the sine curve, from 0 to π, revolved around the z - axis.

A differential area element is then dA = z dx. Revolving this around the z - axis gives the differential volume element,

dV = 2πr dA

dV = 2π (z dx)

dV = 2πy sin(y) dx

Then, integrating (I used integration by parts, u = y, dv = sin(y) dy)

V = 2π{ - y cos(y) + sin(y)} evaluated between π and 0

V = 2π{ ( - π cos(π) + sin(π)) - ( - 0*cos(0) + sin(0)) }

V = 2π²

Then, to 3 decimal places

V = 2(3.14159265)2

V = 19.739

The angle in degrees is 873.1843.

Let the measure of the angle be θ in degrees. Therefore, the measure of the same angle in gradians is (θ × π/180).

According to the given information, the number of degrees of a certain angle added to the number of gradians of the same angle is 152.(θ) + (θ × π/180) = 152.

Simplifying the above equation, we get:(θ) + (θ/180 × π) = 152.

Multiplying both sides of the equation by 180/π, we get:

θ + θ = (152 × 180)/π2θ = (152 × 180)/πθ = (152 × 180)/(3.14)θ = 873.1843

Thus, the angle in degrees is 873.1843.

Answer:

m=25/28

Step-by-step explanation:

The standard form of the equation of this hyperbola with vertices at (12, 0) and (–12, 0) is: y squared over 144 minus x squared over 25 equals 1.

Mathematically, the standard form of the equation of a hyperbola is represented by this mathematical expression:

(y - k)²/a² - (x - h)²/b² = 1          .......equation 1.

Where:

From the information provided above, we have the following parameters:

Vertices = (12, 0) and (–12, 0)

h = 0

k = 0

Asymptote = ±5/12(x) = bx/a      ......equation 2.

Comparing equation 1 and equation 2, we have:

b = 5

a = 12

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

(y - k)²/a² - (x - h)²/b² = 1

(y - 0)²/12² - (x - 0)²/5² = 1

(y - 0)²/144 - (x - 0)²/25 = 1

y²/144 - x²/25 = 1

Answer:

Amanda's method is linear because the number of minutes increased by an equal number every week. Billy's method is linear because the number of minutes increased by an equal factor every week

Step-by-step explanation:

Amount of exercise in minutes for Amanda : 10 , 20 , 30 , 40

Amount of exercise in minutes for Billy : 10 , 20 , 40 , 80

Amanda's amount of exercise increases 10 minutes each week

10 + 10 = 20       20 + 10   = 30       30 + 10 = 40

Billy's amount of exercise increases by factor 2 each week

10 x 2 = 20         20 x 2 = 40           40 x 2 = 80

The required measure of ∠L=25° for the given triangle.

A triangle is a closed shape composed of three angles, three sides, and three vertices. It is one of the most fundamental geometric forms and is represented by the symbol Δ.

If two sides of a triangle are congruent, then the angles opposite those sides are congruent.:

∠KJL = ∠JLK

Substitute ∠KJL = 25° into ∠KJL = ∠JLK: 25° = ∠JLK

∠JLK = 25°

Thus, the required measure of ∠L=25°.
