Answer:

By definition, if two angles are complementary, they both will add up to 90 degrees. Knowing this add 18 and (6d-6) together to equal 90.

18+(6d-6)=90

Subtract 18 from both sides, then add 6. This leaves you with 6d equal to 78. Divide by 6 to get 13.

(6d-6)=72

6d=78

d=13 degrees

Make sure of your answer. You know that d is 13, so plug it back into the equation to see if it equals 90 degrees.

18+6(13)-6=90

18+78-6=90

90=90

What is a triangle?

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.

Based on the sides of a triangle, a triangle is classified into 3 types, namely:

Scalene Triangle – All the sides are of different measures.

Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.

Equilateral Triangle – All the 3 sides of a triangle are of the same measure.

Based on the angles of a triangle, a triangle is classified into 3 types, namely:

Acute Angle Triangle – All the angles of a triangle are less than 90°.

Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.

Right Angle Triangle – One of the angles of a triangle is equal to 90°.

Now,

As sum of all angles of triangles=180°

90+2x+33+5x-34=180

7x=90+1

x=13

Therefore,

                 ∠Q=59°, ∠R=90°,∠S=31°

So the range of probability that at least one bond will default next year is between 0% and 80%.

The probability that at least one of two events will occur is the sum of the probability of each event minus the probability that both events will occur. In this case, the probability that at least one bond will default is:

P(A or B) = P(A) + P(B) - P(A and B)

Where P(A) is the probability of bond A defaulting (50%), P(B) is the probability of bond B defaulting (30%), and P(A and B) is the probability that both bonds will default (which we don't know).

So the range of probability that at least one bond will default is:

P(A or B) = 50% + 30% - P(A and B)

The maximum possible probability of both bonds defaulting is (0.5 * 0.3) = 15% and the minimum possible probability of both bonds defaulting is 0%. Therefore, the range of probability that at least one bond will default is:

P(A or B) = 80% - 0% = 80%

So the range of probability that at least one bond will default next year is between 0% and 80%.

It's important to note that the above formula and the range of probability is based on the assumption of independence, i.e the events of Bond A defaulting and Bond B defaulting are independent and don't affect each other.

The required number of each type of cycles are  25 bicycle and 10 tricycle.

Tricycles will offer better stability and assistance. They can also be applied in a wider variety of circumstances, such as therapy sessions for people with disabilities. The most common vehicle will be a bicycle because they are smaller, lighter, faster, more suited for off-roading, and more widely available.

The seats are counted by 1 for both tricycles and bicycles, so t + b has to equal 35. The only answer choice that has t + b = 35

t = 35 - b

And

3t + 2b = 80

3(35 - b) + 2b = 80

105 - 3b + 2b = 80

105 - b = 80

b = 25

Put value of b in t = 35 - b,we get

t = 35 - 25

= 10

Thus, There are 25 bicycle and 10 tricycle.

Answer: Amber has 50 pennies and 10 dime

Step-by-step explanation:

The number of pennies is represented by x, while the number of dimes is represented by y. This means that the statement, "there are five times as many pennies as dimes" can be written as x = 5.

The sum of the coins is $1.50, which can now be written as

0.01x + 0.1y = 1.50

0.01(5y) + 0.1y = 1.50

0.05y + 0.1y = 1.50

0.15y = 1.50

y = 10

Next up:

x = 5y

x = 5(10)

x = 50

Finally, we can conclude that Amber has 50 pennies and 10 dimes

I hope this helps!

Based on the triangle sum theorem, the value of x is: 45.

The Triangle Sum Theorem states that in any triangle, the sum of the measures of the interior angles is always equal to 180 degrees. This is true for all triangles, regardless of their size or shape.

The theorem can be proven using Euclidean geometry, which states that the sum of the angles in a triangle is always 180 degrees. This theorem is also known as the "angle sum property" of a triangle.

Therefore:

2x + 10 + 30 + 50 = 180 (based on the triangle sum theorem).

Combine like terms:

2x + 90 = 180

2x = 180 - 90

2x = 90

2x/2 = 90/2

x = 45.

The total number (n) of distinct solutions of the equation (x + y + z = 15) with the assumption that x, y and z are all nonnegative integers is 153.

The generating function for the number of solutions of the equation (x + y + z = n) is given by the binomial coefficient (n+2)C2, where C2 is the number of ways to choose 2 objects from a set of n+2 objects.

The number of solutions for the given equation (x + y + z = 15) is then given by:

(15+2)C2 = (17C2)

We can also use the formula for binomial coefficient: nCr = n! / (r! (n-r)!)

17C2 = (17!) / (2! * 15!) = 153

Price paid for car = $23622, The loss value is $3742 and total distance the car was used for is 18000 kilometres.

Distance is a measurement of how far apart two objects or points are. It is the length of the actual route taken to get from one place to another. In physics, distance is frequently used to refer to a physical length or an estimation based on other criteria, such as "a few kilometres apart" or "some miles away."

However, the distance travelled by an object to move from its initial position to its final position will be the same as the distance travelled to move from its final position to its initial position. As a result, distance is independent of a body's motion.

a. Price paid for car = $23622

Discount = 7%

Sale price = $19880

b. The loss value is $3742

c. Let total distance travelled be d

Fuel consumption=10km per litre

Cost of fuel =1.4 per litre

Cost of fuel per kilometre =1.410= 0.14
