if M <1 = 115 degrees what is m <2

Answers

Answer:

M<2= 65

Step-by-step explanation:

The reason it is 65 because 2 angles add up to either 90 or 180 and in this case it would be 180.

You would use angle addition postulate to find the answer so M<1 + M<2 = 180.

Since M<1 is 115 you would substitute it into the formula so 115 + M<2 = 180

Then you would subtract 115 from 180 in which you would get M<2 = 65

The customer must first pay an annual 300 a ductile in the policy covers 70% of cost of x-rays the first Insurance claim for Pacific year submitted by a person or two X-Rays the first x-ray cost 6:40 and the secondary x-ray cost 950 how much in total will he need to pay for these x-rays

Answers

Answer:

$177

Step-by-step explanation:

Given that:

Percentage covered by policy = 70%

Hence, person needs to pay (100 - 70)% = 30%

X - Ray cost :

1st = 640

2nd = 950

Total cost = (640 + 950) = 1590

Amount the person has to pay:

Total cost * 30%

1590 * 0.3 = $477

Since the person has $300 deductible :

$477 - $300 = $177

Write down in terms of n, an expression for the nth term of the following sequences: a) 1 8 15 22 29 B) 12 16 20 24 28

Answers

A)

Sequence: 1 , 8 , 15 , 22 , 29

B)

Sequence: 12 , 16 , 20 , 24 , 28

Difference : 4

Back one : 8

Expression : 4n+8

A sequence is an ordered list of elements with a specific pattern.

The nth term of the sequence:

A) 1  8  15  22  29 is [tex](n-1)^{th}[/tex] + 7.

B) 12  16  20  24  28 is [tex](n-1)^{th}[/tex] + 4.

What is a sequence?

A sequence is an ordered list of elements with a specific pattern.

Example: 2, 5, 8, 11, ... is a sequence where each term is obtained by adding 3 to its previous term.

We have,

a) 1  8  15  22  29

1 + 7 = 8

8 + 7 = 15

15 + 7 = 22

22 + 7 = 29

We see that each term is obtained by adding 7 to the previous term

So, the nth will be in the form:

nth = [tex](n-1)^{th}[/tex] + 7

b) 12  16  20  24  28

12 + 4 = 16

16 + 4 = 20

20 + 4 = 24

2 + 4 = 28

We see that each term is obtained by adding 4 to the previous term.

So, the nth term will be in the form:

nth = [tex](n-1)^{th}[/tex] + 4

Thus the nth term of the sequence:

1  8  15  22  29 is [tex](n-1)^{th}[/tex] + 7.

12  16  20  24  28 is [tex](n-1)^{th}[/tex] + 4.

Use the number line to help you decide which statement is true.

Answers

Answer:

A

Step-by-step explanation:

because 1/2 = 4/8

and 5/8 is greater than 4/8  

The number line is the representation of numbers in real order.

5/8 = 0.625

1/2 = 0.50

5/8 is greater than 1/2.

Option A is the correct answer.

What is a number line?

It is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

Example: Number line from -4 to 4.

-4__-3__-2__1__0__1__2__3__4

We have,

5/8 > 1/2

5/8 = 1/2

5/8 < 1/2

5/8 = 0.625

1/2 = 0.50

We see that,

0.625 > 0.50

So,

5/8 must be greater than 1/2

i.e

5/8 > 1/2

We can also find the relation between 5/8 and 1/2 in this way.

5/8 = 1/2

Cross multiply.

5 x 2 = 8

10 = 8

10 is greater than 8

So,

5/8 is greater than 1/2

5/8 > 1/2

Thus,

5/8 = 0.625

1/2 = 0.50

5/8 is greater than 1/2.

Option A is the correct answer.

determine if the following lengths make a triangle 6,3,7

Answers

Answer:

Yes

Step-by-step explanation:

The rule is that if a+b>c, then it's a triangle. In this case, 6+3>7, so it's a triangle. The hypotenuse (7) should always be the largest of the sum of the two side lengths.

Answer:

Yes, the lengths will create a triangle.

Step-by-step explanation:

6 + 3 = 9 > 7

3 + 7 = 10 > 6

6 + 7 = 13 > 3

If the combination of any lengths is greater than the remaining length, then the lenghts will create a triangle.

The dataset below represents the population densities per square mile of land area in 15 states in the 2010 U.S. Census. What is the interquartile range?

Answers

Answer:

The Interquartile range is 188

Step-by-step explanation:

Missing Data:

1,19,35,43,49,55,63,94,105,110,175,231,239,351,738

Required

Determine the Interquartile range (IQR)

The given data is ordered already.

First, we need to determine the median

For odd number of data

Median = ½(n + 1)th

In this case, n = 15; so

Median = ½(15 + 1)th

Median = ½(16)th

Median = 8th

This implies that the median is at the 8th position.

So, we have:

1,19,35,43,49,55,63 ----> Lower

(94) ---- Median

105,110,175,231,239,351,738 ---- Upper

Next, we determine the median of the lower and upper sets.

These are called lower quartile (Q1) and upper quartile (Q3) respectively

Lower: 1,19,35,43,49,55,63

Number of data, n = 7

Q1 = ½(n + 1)th

Q1 = ½(7 + 1)th

Q1 = ½(8)th

Q1 = 4th position

From the list of data in the lower set,

Q1 = 43

Upper: 105,110,175,231,239,351,738

Number of data, n = 7

Q3 = ½(n + 1)th

Q3 = ½(7 + 1)th

Q3 = ½(8)th

Q3 = 4th position

From the list of data in the upper set,

Q3 = 231

IQR is then calculated as thus:

IQR = Q3 - Q1

IQR = 231 - 43

IQR = 188

If a = –2 + 2i and b = -5i, then find the value of the ab^3 in
fully simplified form.

Answers

Answer:

Step-by-step explanation:

Rewrite the equation

Start multiplying

Simplify

The value of ab³ in simplified form is equal to -250(i + 1).

What is an equation?

Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation. For an unknown quantity represented by an unknown variable, equations are then solved to determine its value. A statement is not even an equation if there is no "equal to" sign in it.

From the given values in the question,

a = -2 + 2i

b = -5i

ab³ = (-2 + 2i) × (-5 i)³

=  (-2 + 2i) (-125 i³)

=  (-2 + 2i) (-125 (-i))

=  (-2 + 2i) (+125 i)

= 125 i(-2) + 125 i(2i)

= -250 i + 250 i²

= -250 i -250 or,

ab³ = -250 (i+1)

Answers

Answer:

A. Approximately 85 m

Step-by-step explanation:

edge

The required distance between the origination point and the target point is 85 m.

What are trigonometric equations?

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

Here,
The distance between the origination point and mirror 1 is 120 m and between mirror 1 and mirror 2 = 90 m

From geometry, the measure of the angle Opposite the distance between the origination point and the target is given as,
= 20 + 25 = 45°

Let,

a = x

b = 90 m

c = 120 m

A = 45°

Following the cosine rule,

a² = b² + c² -2bccosA

a² = 90² + 120² - 2×90×120×cos45
a = √7226.5
a = 85.008

a ≈ 85

Thus, the required distance between the origination point and the target point is 85 m.
