Step-by-step explanation:

The angle of incline, of the target θ = 14.036.

The angle of elevation or depression can be calculated using the following formula: t a n = O A, where A is the horizontal distance between the observer and the point and O is the length of the side opposite the angle of elevation or depression, or the object's perpendicular distance from the horizontal line.

To calculate the slope percentage, multiply the result by 100 after dividing the height difference between two points by their separation. The rise is the height difference between two locations. The distance between the locations is known as the run. The result is that (rise / run) x 100 is equal to the percent slope.

Given,

the height of triangle = 12in

base of triangle = 48 in

tan θ = perpendicular / base

tanθ = 12/48

θ = tan ⁻¹( 12/48)

θ = 14.036

Addition is commutative because the order in which two numbers are added does not affect the result.

Commutative property is applicable only for addition and multiplication processes. Thus, it means we can change the position or swap the numbers when adding or multiplying any two numbers.

Addition is commutative because the order in which two numbers are added does not affect the result. For example, 1 + 2 = 2 + 1 = 3. In contrast, subtraction is not commutative because the order in which two numbers are subtracted does affect the result. For example, 1 - 2 = -1, but 2 - 1 = 1. The operation is different when the order of the numbers are changed.

so, addition is commutative because the order in which two numbers are added does not affect the result.

The length of BC is 5.7 cm

A dot is used to symbolise a point, which is a place in any space (.). It does not have any size, shape, length, or height. A line segment has a beginning and an end, but a line is stretched in both directions towards infinity.

It is given that the length of AB is 8.6 cm and length of AD is 20 cm.

Also, BC=CD

As there are 4 points (A, B, C, D) on the line and the length of the lone is 20 cm, we     can say

AB+BC+CD= 20 --------------- (1)

Let us consider that BC=CD= x (say)

Substituting the values in equation (1),

8.6+ x+ x=20

Or, 2x =11.4

Or, x=11.4/2

Or, x=5.7 cm

Therefore, we can say that the length of BC is 5.7 cm.

The probability that you win first prize and your friend wins second

prize is option D: 13/2730.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Total number of prizes awarded = 3

Number of people entering the drawing competition = 15

Number of ways to award the prize = 2730

Out of the 3 prizes the first and the second is needed.

So, the prize for the first and the second positions are fixed and there is no need to consider the remaining 13 people to win the prize.

Hence the remaining number of people who can win the 3rd prize  = 13

The number of ways one of them wins the 3rd prize = 13

The total number of ways = 2730

Therefore, the probability of the first 2 prizes fixed and the remaining 3rd awarded to the rest of the 13 people is 13/2730.

Mariela spends $50 on a used microwave. By 60%, she raises the price. When a 5.8% sales tax is additionally included, the ultimate cost is 20 in 60% and 47.1 in 5.8%.

Cost plus markup % multiplied by cost is the formula used to increase a product's markup percentage. Let's say you're utilising a markup of 60% and the item costs $75. multiplying by 60 percent $75. Now you have $45. For instance, the markup percentage would be 50% if the cost to produce your product was $50 and the selling price was                      $75: ($75 - $50) / $50 =.50 × 100=50%.

0.6 is 60 hundredths of a unit, thus write it as 0.60. 60% is equal to 60 hundredths. The decimal point can alternatively be shifted two places to the right to find the % equivalent. As a result, the markup equation is now: markup = 100 × (revenue - cost) / cost. Last but not least, use revenue = cost + cost × markup / 100 to determine the selling price.

A proportion is two ratios that have been set equal to each other; a proportion is an equation that can be solved. When I say that a proportion is two ratios that are equal to each other, I mean this in the sense of two fractions being equal to each other. For instance, 5/10 equals 1/2.

Given that 4/9 of the fans in a football match are men and 200 are women. We must determine the total number of spectators at the football game.

If 4/9 of the total spectators are men, the remaining 5/9 are women.

Let x be the total number of spectators.

Mathematically,

5/9 of x = 200

5/9 × x = 200

5x = 1800

X = 360

As a result, the total number of spectators is 360.

The number of male spectators may also be calculated.

Males + Females = Total number of spectators

360 = Males + 200

Answer: Area = 28.3cm²

               Circumference =  18.9cm

Step-by-step explanation:

Area = πr²

        = π × 3²

        = 28.27

        = 28.3cm² (estimate to 3s.f always)

Circumference = 2πr

                          = 2 x π x 3

                          = 18.85

                          = 18.9cm (estimate to 3s.f always)

The area and the circumferences of the circle are 28.27 square meters and 18.85 meters.

Given is a circle with radius 3m we need to determine the area and the circumferences of the circle,

To determine the area and circumference of a circle with a radius of 3m, we can use the following formulas:

Area of a circle: A = πr²

Circumference of a circle: C = 2πr

Here, "r" represents the radius of the circle, and "π" (pi) is a mathematical constant approximately equal to 3.14159.

Let's calculate the values:

Area:

A = πr²

A = 3.14159 x (3m)²

A = 3.14159 x 9m²

A ≈ 28.27 square meters

Therefore, the area of the circle is approximately 28.27 square meters.

Circumference:

C = 2πr

C = 2 x 3.14159 x 3m

C ≈ 18.85 meters

Therefore, the circumference of the circle is approximately 18.85 meters.

Hence the area and the circumferences of the circle are 28.27 square meters and 18.85 meters.

Answer:

Step-by-step explanation:

To solve the system of equations using substitution, we first need to isolate one of the variables in one of the equations. We can start by solving the first equation for y:

x - 5y = -6

y = (x + 6) / 5

Now we can substitute this expression for y into the second equation:

7x - 3y = 42

7x - 3((x + 6) / 5) = 42

Simplifying and solving for x:

(35/5)x - (3/5)x - 18/5 = 42

32x = 210+18

x=57/8

Now we can substitute this value of x back into the first equation to find the value of y:

y = ((57/8) + 6) / 5

y = 21/8

So the solution of the system is (x, y) = (57/8, 21/8).
