Your job is to figure out how to make a "silver mile". Here in the United States we could do this with nickels, dimes, quarters, half-dollars, or silver dollars. I found on the United States Mint website that the Susan B. Anthony silver dollar was 1.04 inches in diameter. Making a mile using just this coin would be an easy calculation. We need a more interesting challenge. We are going to create a silver mile following a specific set of rules. You may need to cover a little more than the required distance since you cannot use fractional parts of the coins. Here are the rules:
1) Lay down enough Susan B. Anthony silver dollars to cover half of the mile.

2) Cover one-third of the remaining distance with half-dollars.

3) Use quarters to cover one-fourth of the remaining distance.

4) With dimes, cover one-fifth of the remaining distance,

5) Fill in the remaining distance with nickels.

What is the total value of the coins in this mile?

Please support this by showing evidence. Thanks a lot :)​

Answer:

The first coordinate plane has a constant additive rate of change of -1/4

Step-by-step explanation:

Additive rate of change is determined using the slope formula:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

It must be applied to all of the coordinates given, as sometimes, answer options will have the right slope for the first few options but then change it later in the list. Remember that this is a constant rate of change; it must be the same throughout all of the coordinates.

The first coordinate plane with (-2, 2) and (2, 1) is

[tex]m=\frac{1-2}{2-(-2)} =-0.25[/tex]

so this is the answer. I encourage you to look below to see why the others are not the answer, as there are some tips throughout the rest of my response.

The second plane is a curved line, and this means that it is a function with some kind of exponent or log (judging by the shape, it is probably a quadratic function). Regardless, it will not have a constant change from point to point because of the curve. This is not the answer for those reasons.

The first table is linear (with a constant slope), so that meets the first requirement. The slope, however, is -1/2, so it is not what we are looking for. This is also not the solution.

The last table has a positive slope of 3.3, so this does not fit what we want from an answer.

Hope this helps :)

cos(32) = 0.8480480962

cos(58) = 0.5299192642

cos(68) = 0.3746065934

sin(32) = 0.5299192642

sin(58) = 0.8480480962

Cos(58) = sin(32)

Answer:

x =5.5

Step-by-step explanation:

The directions say to use x for the number.

"take 10 away from"

x - 10

"then square the result"

(x - 10)^2

"I get the same answer" means the two expressions will be equal to each other.

"if I square my number"

x^2

"then subtract 10 from the result"

x^2 - 10

SET EQUAL TO EACH OTHER.

(x - 10)^2 = x^2 -10

Multiply on the left side.

x^2-20x+100 =x^2-10

subtract x^2 from both sides.

-20x + 100 = -10

subtract 100.

-20x = -110

divide by -20

x = 11/2 or 5.5

CHECK:

(5.5-10)^2=20.25

5.5^2 - 10=20.25

The number would be equal to x =5.5

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The directions say to use x for the number means x - 10

"then square the result" means (x - 10)^2

"I get the same answer" means the two expressions will be equal to each other.

"if I square my number" means x^2

"then subtract 10 from the result" means x^2 - 10

therefore,

(x - 10)^2 = x^2 -10

Now Multiply on the left side.

x^2-20x+100 =x^2-10

Then subtract x^2 from both sides.

-20x + 100 = -10

-20x = -110

x = 11/2 or 5.5

C = 100

Step-by-step explanation:

Supplementary angles equal 180 degrees

180 - 80 = 100

Answer:

m∠C = 100°

Step-by-step explanation:

Supplementary angles are angles that add up to 180°. We are given m∠D as 80°.

Step 1: Subtract 80 from both sides.

Therefore, the answer is 100°.

Answer:

-4 is rate

7 is change

Step-by-step explanation:

Take what x is multiplying and that is your rate and change.

Answer:

x = 4

Step-by-step explanation:

To see when g(x) = f(2)

First, find f(2)

f(2) = 3(2) - 1 = 5

Now g(x) = 2x-3  = f(2) = 5

2x - 3 = 5

Adding 3 to both sides

2x = 8

Dividing 2 on both sides

x = 4

The sample who prefer a finished basement is 126 homeowners

Given the following parameters

The total number of people surveyed = 300 homeowners

If a realtor has been told that​ 43% of homeowners in a city prefer to have a finished basement, the sample of owners that prefer a finished basement is expressed as:

Sample of owners = 43% of 300

Sample of owners = 0.43 * 300
Sample of owners = 126

Hence the sample who prefer a finished basement is 126 homeowners

Answer:

The equation on the graph is: y = -(x+1)(x-6)

The expression that is not a variation of the Pythagorean identity is the third option.

The Pythagorean identity can be written as:

[tex]sin^2(x) + cos^2(x) = 1[/tex]

For example, if we subtract cos^2(x) on both sides we get the second option:

[tex]sin^2(x) = 1 - cos^2(x)[/tex]

Which is a variation.

Now, let's divide both sides by cos^2(x).

[tex]sin^2(x)/cos^2(x) + cos^2(x)/cos^2(x) = 1/cos^2(x)\\\\tan^2(x) + 1 = sec^2(x)\\\\tan^2(x) - sec^2(x) = -1[/tex]

Notice that the third expression in the options looks like this one, but the one on the right side is positive. The above expression is in did a variation of the Pythagorean identity, then the one written in the options (with the 1 instead of the -1) is incorrect, meaning that it is not a variation of the Pythagorean identity.

Concluding, the correct option is the third one.

Answer:

about 15.8 inches

Step-by-step explanation:

Use the equation [tex]a^{2} + b^{2} = c^{2}[/tex]

Where "a" and "b" are the leg lengths and "c" is the hypotenuse.

The solution is, 15.8 inches is the approximate length of the hypotenuse.

here, we have,

given that,

A right triangle has legs that are 10.1 inches and 12.2 inches long.

We only need to apply Pythagoras theorem to solve this problem.

Pythagoras theorem state that in a right-angle triangle,

opposite² + adjacent²  = hypotenuse²

From the question, the length of the leg = 10.1 inches

one of the leg, lets say adjacent = 12.2 inches

Let x be the hypotenuse of the other leg.

We can now proceed to insert our values into the formula;

opposite² + adjacent²  = hypotenuse²

        10.1²    +      12.2²           = x²

so, we get,

x²  = 10.1² + 12.2²  

x²  = 102.01 + 148.84

x²   =  250.85

Take the square root of both-side to get the value of x

√x²   =  √250.85

x = 15.83

x≈15.8

Therefore the approximate length of the other leg is 15.8 inches.
