Answer:

29107

Step-by-step explanation:

Every next 'level', a ring of balls is added.

The ring has 6 sides of n balls, but you would then count all 6 corners double, so you have to subtract 6.

So Bₙ = Bₙ₋₁ + 6n - 6

This gives you a sequence of 1, 7, 19, 37, 61, 91, 127, 169, 217, 271, 331, ...

All the way up to 29107 at 100 balls.

Answer:  Equation that represents this situation is 5(x+17) = 1495,

Price of one ticket is 282

Step-by-step explanation:

Here x represents the price of one ticket,

Also, a person bought travel insurance that costs $17 per ticket.

Hence, the total cost of a person = x + 17

⇒ The total cost of 5 person = 5 ( x + 17 )

But, According to the question,

5 ( x + 17 ) = 1495

⇒ x + 17 = 299

⇒ x = 299 - 17

⇒ x = 282

Hence, the price of one ticket = $ 282

Answer:

Mean:8

Median:8.5

Mode:9,4

Step-by-step explanation:

Mean Steps:

mean(5,9,7,12,6,4,10,8,14,9,4)

To find the mean of the set 5,9,7,12,6,4,10,8,14,9,4 first add the members together.

5+9+7+12+6+4+10+8+14+9+4=88

The mean (average) of the set 5,9,7,12,6,4,10,8,14,9,4 is found by dividing the sum of its members by the number of the members, in this case 11.

88/11 = 8

Mode Steps:

Mode(5,9,7,12,4,10,8,14,9,4)

The mode of a set is the value that appears most often. The mode can have more than one value if two or more values appear the same number of times and more times than any other values in the set.

mode(5,9,7,12,4,10,8,14,9,4)

Putting the numbers in order can make it easier to find the mode because values that appear more than once will be next to each other.

4,4,5,7,8,9,9,10,12,14

In this case the mode has more than one value because 9 and 4 both appear 2 times, more often than any other values.

mode(4,4,5,7,8,9,9,10,12,14)=9,4

Answer:

69

Step-by-step explanation:

150x.46=69

or

half of 100 is 50

46% of 50 =23

23+46=69

Answer:

After 5 years, the account will have earned $ 639.13 in interest.

Step-by-step explanation:

Given that Mr. and Mrs. kinkaid open a certificate of deposit account that pays 1.45% interest compounded daily, to determine how much interest will the account earn in 5 years on their deposit of $ 8,500, the following calculation must be performed:

X = 8500 (1 + 0.0145 / 365) ^ 5x365

X = 8500 (1 + 0.0145 / 365) ^ 1825

X = 9,139.13

9,139.13 - 8,500 = 639.13

Thus, after 5 years, the account will have earned $ 639.13 in interest.

Answer:

SAS for similarity

Step-by-step explanation:

I can tell you from this is that ∠TUS ≅ ∠WUV, because they are vertical angles.

The triangles cant be congruent by SSS, SAS, or ASA because the sides are not equal.

However, they are similar because 45/15 = 3 and 36/12 = 3. That would be the SAS for similarity.

Step-by-step explanation:

Answer:

[tex]-1.5x - 3.5y =- 31.5[/tex]

Step-by-step explanation:

Given

AB: [tex]-7x + 3y = -21.5[/tex]

[tex]PQ(x_1,y_1) = (7,6)[/tex]

Required

Determine the equation of PQ

First, we calculate the slope of AB:

[tex]-7x + 3y = -21.5[/tex]

Make 3y the subject

[tex]3y = 7x - 21.5[/tex]

Make y the subject

[tex]y = \frac{7}{3}x - \frac{21.5}{3}[/tex]

An equation has the general form:

[tex]y = mx + b[/tex]

Where m = slope

So:

[tex]m = \frac{7}{3}[/tex] -- Slope of AB

From the attached diagram, we can see that PQ is perpendicular to AB.

This means that, the relationship between their slope is:

[tex]m_2 = -\frac{1}{m_1}[/tex]

Substitute 7/3 for m1

[tex]m_2 = -\frac{1}{7/3}[/tex]

[tex]m_2 = -\frac{3}{7}[/tex]

The equation of PQ is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = m_2 = -\frac{3}{7}[/tex]

and

[tex]PQ(x_1,y_1) = (7,6)[/tex]

So, we have:

[tex]y - 6 = -\frac{3}{7}(x - 7)[/tex]

Multiply both sides by 7

[tex]7(y - 6) = -\frac{3}{7}(x - 7)*7[/tex]

[tex]7y - 42 = -3(x-7)[/tex]

Open bracket

[tex]7y - 42 = -3x + 21[/tex]

Collect Like Terms

[tex]3x + 7y = 42 + 21[/tex]

[tex]3x + 7y = 63[/tex]

Divide through by -1/2

[tex]-\frac{1}{2}(3x + 7y) = -\frac{1}{2}*63[/tex]

[tex]-1.5x - 3.5y =- 31.5[/tex]

The equation of PQ is: [tex]-1.5x - 3.5y =- 31.5[/tex]

Answer:

B. -1.5x − 3.5y = -31.5

Step-by-step explanation:

Answer:

C) x = -2 ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

3x² + 12x - 9 = 0

divide through by 3

x² + 4x - 3 = 0

add 3 to each side

x² + 4x = 3

divide 4 in half and square it; add it to each side of equation

x² + 4x + 4 = 3 + 4

(x + 2)² = 7

x + 2 = [tex]\sqrt{7}[/tex]

x = -2 ± [tex]\sqrt{7}[/tex]

The functions whose graphs include the point (4,1) are y = (1/4)x and y = x - 3

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

To check whether a point is on the graph of a function, we can substitute the coordinates of the point into the equation of the function and see if the equation is true.

Substituting (4, 1) into each of the functions, we get:

A: y = 2x -> 1 = 2(4) = 8 (false)

B: y = (1/4)x -> 1 = (1/4)(4) = 1 (true)

C: y = x + 12 -> 1 = 4 + 12 = 16 (false)

D: y = x - 3 -> 1 = 4 - 3 = 1 (true)

E: y = x^2 -> 1 = 4^2 = 16 (false)

Therefore, the functions whose graphs include the point (4,1) are y = (1/4)x and y = x - 3
