How much will Bill pay in Medicare if he makes $100,000 next year?

Answer:

I Believe Its Eight Squares

There are 450 triangles, we can pick that do not form an equilateral triangles when 15 dots are evenly spaced on the circumference of a circle.

An equilateral triangle is a triangle with all three sides of equal length , corresponding to what could also be known as a "regular" triangle.

here, we have,

Let's calculate the total no. of possible triangles, it depends on the combination. To make a triangle, we have to choose 3 dots out of 15.

Here, we will use the combination rule to find out the possible triangles,

Thus, the total number of possible triangles = 15C3                                                                      = (15.14.13) / (1.2.3) = 455

Note that an equilateral triangle would be formed by connecting 3 equally spaced dots.

For an equilateral triangle, out of 15 dots, there would be 15 - 3 = 12 dots that will not be connected.

And 12/3 = 4 dots would be between any two connecting dots.

Taking 1st connecting dot, the second connecting dot would be

1 + 4 + 1 = 6th

Similarly, the third connecting dot would be 6 + 4 + 1 = 11th

So, the following connecting dots will form equilateral triangles: (1, 6, 11); (2, 7, 12); (3, 8, 13); (4, 9, 14); (5, 10, 15);

After applying the combination rule we found the total number of the possible triangle and there are 5 equilateral triangles:

So, there are 455 - 5 = 450 triangles that are not equilateral triangles.

fifteen dots are evenly spaced on the circumference of a circle. how many combinations of three dots can we pick from these 15 that do not form an equilateral triangle?

Answer:

300 min or 5 hours

Step-by-step explanation:

so if it pumps 0.5 gallons per minute than in 2 minutes it would pump 1 whole gallon so with that we know 1gallon=2 minutes.

so with that we multipy both sides by 150 which will be 150 galons=300 minutes or 5 hours

Answer:

x=-2500

Step-by-step explanation:

[tex]\sqrt{-4x} =100\\\\(\sqrt{-4x})^2=100^2\\\\-4x=10,000\\\\x=-\frac{10000}{4}\\\\x=-2500[/tex]

The given can be solved by simplifying the equation to make x the subject

of the equation.

Reasons:

The equation is; √(-4·x) = 100

The above equation can be expressed as follows;

By squaring both sides, we get;

[tex]\displaystyle \mathbf{ \left(-4 \cdot x \right)^{\frac{1}{2} \times 2 }} = 100^2[/tex]

Which gives;

[tex]\displaystyle \left(-4 \cdot x \right)^{\frac{1}{2} \times 2 } = \left(-4 \cdot x \right)^{1 }= -4 \cdot x = 100^2[/tex]

[tex]\displaystyle -4 \cdot x = 100^2 = 100 \times 100 = \mathbf{10,000}[/tex]

[tex]\displaystyle -4 \cdot x = 10,000[/tex]

Dividing both sides by -4 gives;

[tex]\displaystyle x = \mathbf{ \frac{10,000}{-4} } = -2,500[/tex]

Therefore'

x = -2,500

Number of children bicycles = 117

Step-by-step explanation:

Given that:

Number of adult bicycles = a =  42

Let,

x represent the number of children bicycle

According to given statement;

The number of children bicycle is nine less three times the number of adult bicycles.

x = 3a - 9

Putting a=42

x = 3(42)-9

x = 126-9

x = 117

Hence,

Number of children bicycles = 117

Step-by-step explanation:

.................

Answer:

42, 122, 202

Step-by-step explanation:

The sequence is going up by 20s.

Answer:

Simplifying

5(x + 9) = 5x + 45

Reorder the terms:

5(9 + x) = 5x + 45

(9 * 5 + x * 5) = 5x + 45

(45 + 5x) = 5x + 45

Reorder the terms:

45 + 5x = 45 + 5x

Add '-45' to each side of the equation.

45 + -45 + 5x = 45 + -45 + 5x

Combine like terms: 45 + -45 = 0

0 + 5x = 45 + -45 + 5x

5x = 45 + -45 + 5x

Combine like terms: 45 + -45 = 0

5x = 0 + 5x

5x = 5x

Add '-5x' to each side of the equation.

5x + -5x = 5x + -5x

Combine like terms: 5x + -5x = 0

0 = 5x + -5x

Combine like terms: 5x + -5x = 0

0 = 0

0 = 0

Answer:

  7.51 m

Step-by-step explanation:

The distance traveled to the first floor hit is 1 m. The next hit has a height that is 14% less, so is 100% -14% = 86% = 0.86 times this height. The travel up and down to/from that height is added to the total.

The distance traveled to the second floor hit is 1 m + 2×(0.86×1 m).

The distance traveled to the third floor hit is 1 m + 0.86×2 m + 0.86²×2 m.

Then the distance traveled to the n-th floor hit is ...

  -1 m + Sum(0.86^k × 2 m) for k = 0 to n-1

The sum can be found from the formula for the sum of a geometric series:

  Sn = a1×(r^n -1)/(r-1) . . . . . where a1 is the first term and r is the common ratio.

For r = 0.86, n = 6, and a1 = (2m), the total distance is ...

  vertical distance = -1 m + (2 m)(0.86^6 -1)/(0.86 -1)

  = -1 m + (2 m)(-0.5954)/(-0.14) ≈ 7.5062 m

The total distance traveled to the 6th floor hit is about 7.51 meters.

172 coins equal $14.00

It took time to figure this out, I just used a calculator to shimmy down the gap of possibilities, starting here;

100d = $10.00

72n = $3.60

I got closer here;

110d = $11.00

62n =$3.10

I subtracted 2 dimes and added 2 nickels from the previous to get the answer.

108d = $10.80

64n = $3.20

$10.80 + $3.20 = $14.00

Answer:

5485/45

Step-by-step explanation:

Answer:

a. This function therefore exhibits a constant return to scale.

b. The reason is that the sum of the exponents of the multiplicative factor a is equal to 1.

Step-by-step explanation:

The given production function is first correctly stated as follows:

Q = A L^½ K^½ .......................... (1)

In order to know the returns to scale this function exhibits, the input K and L are scaled by the multiplicative factor a which is included in equation (1) as follows:

Q = A (aL)^½ (aK)^½

Q = A a^½L^½ a^½K^½

Q = A a^½ a^½ L^½  K^½

Q = A a^(½+½) L^½  K^½

Q = A a^1 L^½  K^½ ......................... (2)

Based on the equation (2), we now answer the following questions:

a. What returns to scale, does this function exhibit?

This function therefore exhibits a constant return to scale.

b. Why?

The reason is that the sum of the exponents of the multiplicative factor a in equation (2) is equal to 1.

Answer:

a. 48 salads were bought on Wednesday

b. 42 chickens were bought on Thursday

c. 39 cheese were bought on Friday

Step-by-step explanation:

Given

[tex]------- M -- T - W -- T -- F[/tex]

Cheese ----- 50 -- 45 - 52 - 47 --39

Salad -------- 61 -- 44 - - 48 - 38 -- 51

Chicken ---- 53 -- 46 - - 39 - 42 -- 52

First, it should be noted that the horizontal data represent the row while the vertical data represent the column.

Having said that, the solution is as follows:

Solving (a): Second Row, Third column

The data at the second row are:

[tex]------- M -- T - W -- T -- F[/tex]

Salad -------- 61 -- 44 - - 48 - 38 -- 51

The data at the third column is then limited to:

------------------W

Salad -------- 48

So the number at this position implies that: 48 salads were bought on Wednesday

Solving (b): Third Row, Fourth column

The data at the second row are:

[tex]------- M -- T - W -- T -- F[/tex]

Chicken ---- 53 -- 46 - - 39 - 42 -- 52

The data at the fourth column is then limited to:

------------------- T

Chicken ---- 42

So the number at this position implies that: 42 chickens were bought on Thursday

Solving (c): First Row, Fifth column

The data at the first row are:

[tex]------- M -- T - W -- T -- F[/tex]

Cheese ----- 50 -- 45 - 52 - 47 --39

The data at the fifth column is then limited to:

------------------F

Cheese ----- 39

So the number at this position implies that: 39 cheese were bought on Friday
