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!

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 distance-time graphs for the given scenarios have been attached below. The solution has been obtained using distance-time function.

What is distance-time function?

The distance between a person and an object through time is described by distance-time functions. Depending on the kind of movement, a distance-time function may be linear or non-linear, increasing, decreasing, or constant. We need to tell where the object starts, what direction it moves in, how quickly it moves, and whether it is speeding up, slowing down, or travelling at a constant speed in order to explain a distance-time function.

a. The distance-time graph for this scenario is the first graph wherein the line is less steeper than the other graph because the speed is constant.

b.  The distance-time graph for this scenario is the second graph wherein the line is steeper than the first one because the speed is changing from slow to fast.

The path of the rocket can be modeled by the equation

h(t) = -16t² + 80t

We know that the range of a projectile is nothing but the horizontal distance the projectile travels from the time it is launched to the time it comes back down to the same height at which it is launched.

To find the horizontal distance we find the distance between the points on the horizontal axis.

i.e., to find the value of t for which h(t) = 0

Let us assume that the value of equation h(t) = 0

h(t) = 0

-16t² + 80t = 0

t(-16t + 80) = 0

t = 0   OR   -16t + 80 = 0

t = 0   OR  -16t = -80

t = 0   OR  t = 5

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

Answer: (0, -1)

Step-by-step explanation:

Hello! One method you can use to solve a system of equations is the elimination method.  Here are the steps to use the elimination method in this equation:

 -4y + x = 4               -4y - (-6y) = -4y + 6y = 2y, x -x = 0, 4 - 6 = -2
- (-6y + x = 6)
_________
2y = -2
__    __
2       2

y = -1

You now know that y = -1 for both lines to intersect.  Let's now find x using the substitution method.

Use the equation -4y + x = 4.  Substitute -1 for y in the equation.

-4(-1) + x = 4
4 + x = 4
-4      =  -4
x = 0.  

You now know that x = 0 and y = -1.  Coordinate pairs are represented as (x, y).  Substitute 0 in for x and -1 in for y.  Your answer is (0, -1).

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

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

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
