A^n =16 + (N - 1) (-0.5), 15th term
Find the indicated term of the arithmetic sequence.

Answer:

Step-by-step explanation:

Alina=2x---eq(1)

Asim=5x----eq---(2)

So,we get

2x+5x=210

7x=210

x=30

Now,Putting '30' in eq 1 and eq 2

2*30=60

5*30=150

Therefore Alina got 60 Rs while Asim got 150 Rs

Step-by-step explanation:

Answer:

a. $12,600

b. $21

c. $19

Step-by-step explanation:

a) The cost is $3000 plus $16 per book

For 600 books, we have

3000 + 16(600)

= 3000 + 9600 = $12,600

b) Cost per book will be;

12,690/600 = $21

c) for 1000

= 3000 + 16(1000)

= 3000 + 16,000 = 19,000

cost per book is 19,000/1000 = $19

Answer:

- 2.368

Step-by-step explanation:

Given that :

Mean (m) = 172. 5

Standard deviation (s) = 1.9

Score (x) = 168

The Zscore can be obtained thus :

Zscore = (x - m) / s

Zscore = (168 - 172.5) / 1.9

Zscore = - 4.5 / 1.9

Zscore = −2.368421

Zscore = - 2.368

Answer:

= $1.36

Step-by-step explanation:

[ 2(3.45) + 3(4.82) ] - 20

= [ 6.9 + 14.46 ] - 20

= [ 21.36 ] - 20

= $1.36

Equation of the line in intercept form

The intercept form of the equation of a line is:

[tex]\displaystyle \frac{x}{a}+\frac{y}{b}=1[/tex]

Where:

a = x-intercept

b = y-intercept

The standard form of a line is:

Ax + By = C

The given line has a=6 and b=-2, thus:

[tex]\displaystyle \frac{x}{6}+\frac{y}{-2}=1[/tex]

Multiplying by 6:

x - 3y = 6

This is the required standard form of the line.

Thus, the standard form of the line is:

x - 3y = 6

Math

Answer:

Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.

Step-by-step explanation:

The general equation of a straight line is

y = mx + b

for y = 150x

We have the slope as 150

This is 150 miles/hour

This relates to Jesse’s train speed

for Khalid, we have his own speed obtainable from the graph

The speed is simply the slope of the graph

We proceed to select two points from the graph and find the slope

The points are; ((1,140) and (4,560)

Mathematically, the slope will be;

m = (y2-y1)/(x2-x1)

m = (560-140)/(4-1) = 420/3 = 140 miles per hour

THe answer is true

Answer:

is this the whole question? is there a second part to it?

Answer:

A: 0

B: pi/3

E: 5pi/3

Step-by-step explanation:

The solution to the trigonometric equation is 0 , π/3 , 5π/3

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the trigonometric equation be represented as A

sin ( x/2 ) + cos ( x ) - 1 = 0

sin ( x/2 ) - ( 1 - cos ( x ) ) = 0

On further simplification , we get

( 1 - cos ( x ) ) = 2sin² ( x/2 )

So , sin ( x/2 ) - 2sin² ( x/2 ) = 0

Taking sin ( x/2 ) as the common factor , we get

sin ( x/2 ) ( 1 - 2sin ( x/2 ) ) = 0

So , the solutions to the equation are

sin ( x/2 ) = 0

x = 0 , 2π

And , ( 1 - 2sin ( x/2 ) ) = 0

sin ( x/2 ) = 1/2

x = π/3 , 5π/3

Hence , the solutions are x = 0 , π/3 , 5π/3

Answer:∠1 = ∠3 = ∠5 = ∠7 = 77.5°

∠2 = ∠4 = ∠6 = ∠8 = 102.5°

Step-by-step explanation:

In the picture attached, the parallel lines and the transversal are shown.

8 angles are formed, where:

∠1 ≅ ∠3 ≅ ∠5 ≅ ∠7

∠2 ≅ ∠4 ≅ ∠6 ≅ ∠8

On the other hand, ∠1 + ∠2 = 180°, and ∠2 is 25° greater than ∠1, that is ∠1 + 25° = ∠2, therefore:

∠1 + ∠1 + 25° = 180°

2∠1 = 180° - 25°

∠1 = 155°/2

∠1 = 77.5°

and

∠2 = 77.5° + 25° = 102.5°

Answer:

<1=<5

<4=<8

<2=<6

<3=<7[these all are corresponding angle]

<1=<3

<4=<2

<8=<6

<5=<7 [these all are vertically opposite angle]

let<1=70°

than

<1=<5=<7=<3=77°

again

<1+<2=180°[linear pair]

<2=180°-72=98°

Than

<2=<6=<4=<8=98°

b One angle is 25° greater than another.

let <1=x than <2=<x+25°

<1+<2=180°[linear pair]

x+x+25=180°

2x=180-25

x=155.2

x=77.5°

x+25=77.5°+25°=102.5°

either

<1=<5=<7=<3=77°

<2=<6=<4=<8=102.5°

Or

<1=<5=<7=<3=102.5°

<1=<5=<7=<3=102.5°<2=<6=<4=<8=77°

Answer:

They will spend less at the sunny side hotel

Step-by-step explanation:

The attachment completes the question.

From the question, we understand that there are 4 individuals involved.

And they will spend one night

First, we need to calculate the expenses in Traveler's hotel.

[tex]Rate = \$107.10[/tex] (for 3 people)

[tex]Additional\ Person = \$21.55[/tex] (for 1 person)

[tex]Breakfast = \$8.75 * 4[/tex] (for 4 people)

[tex]Tax = \$16.85[/tex]

Total Expenses

[tex]Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85[/tex]

[tex]Total = \$107.10 + \$21.55 + \$35.00 + \$16.85[/tex]

[tex]Total = \$108.50[/tex]

For Sunny Side hotel:

[tex]Rate = \$152.95[/tex] (for 4 people)

[tex]Tax = \$21.34[/tex]

Total Expenses:

[tex]Total = \$152.95 + \$21.34[/tex]

[tex]Total = \$174.29[/tex]

By comparison, they will spend less at the sunny side hotel.

Step-by-step explanation:

The definition of the side splitter theorem is if a line intersects two sides of a triangle and is parallel to the third side of the triangle, it divides those two sides proportionally.  

What that means in this problem is that

x/18=9/54

Now, we just have to simplify that by cross multiplying

54x= 162

Answer:

225 will be correct

Step-by-step explanation:

Step-by-step explanation:

Mass of Zinc = 870g * (40/100) = 348g.

Mass of Copper = 870g - 348g = 522g.

Mass of zinc = 40/100*870 = 348

Mass of Copper = 60/100*870 = 522

Therefore, the mass of zinic in the alloy is 348 and the mass of copper in the alloy is 522.

Answer:

○ D) A and C

Step-by-step explanation:

[tex]\displaystyle \frac{n!}{r![-r + n]!} = {}_nC_r[/tex]

All you need to do is plug each choice into the formula:

[tex]\displaystyle \frac{10!}{2![-2 + 10]!} \Longrightarrow \frac{[2][3][4][5][6][7][8][9][10]}{2[-2 + 10]!} \longrightarrow \frac{[2][3][4][5][6][7][8][9][10]}{2[(2)(3)(4)(5)(6)(7)(8)]} \\ \\ \boxed{45} = \frac{90}{2}[/tex]

OR

[tex]\displaystyle \frac{10!}{8![-8 + 10]!} \Longrightarrow \frac{[2][3][4][5][6][7][8][9][10]}{[(2)(3)(4)(5)(6)(7)(8)][-8 + 10]!} \\ \\ \boxed{45} = \frac{90}{2}[/tex]

So, from what you see, both values of [tex]\displaystyle r[/tex] work. In fact, when using the formula pertaining to combinations, you will see that each result has a “repetitive pattern”. This is something you must look out for when using this formula.
