Are lines l & k parallel?

Answer:

11.2

Step-by-step explanation:

(AB) ^2 - (BC) ^2 = b^2 (Pythogoras Theorem)

(15)^2 - (10)^2 = (b) ^2

b^2=225-100

b^2=125

b=root (125)

b=11.18

b=11.2

Answer:

to find slope we use the following methods

Step-by-step explanation:

given

X1 -2

X2= -4

Y1= 2

Y2= -4

slope=y2-Y1 ÷X2-X1

= -4-2÷ -4-(-2)

=-6 ÷-4+2

= -6÷-2

= 3

slop of (-2,2) (-4,-4) = 3

Answer:

n = 8

Step-by-step explanation:

Continuing the sequence using

[tex]x_{n}[/tex] + [tex]x_{n+1}[/tex]

x₄ = x₂ + x₃ =1 + 2 = 3

x₅ = x₃ + x₄ = 2 + 3 = 5

x₆ = x₄ + x₅ = 3 + 5 = 8

x₇ = x₅ + x₆ = 5 + 8 = 13

x₈ = x₆ + x₇ = 8 + 13 = 21

x₉ = x₇ + x₈ = 13 + 21 = 34

x₁₀ = x₈ + x₉ = 21 + 34 = 55 ← with n = 8

Answer:

The Fibonacci numbers are

1

1

2

3

5

8

13

21

34

55

The eighth Fibonacci Number  is 21, the  ninth  is 34 and the tenth is 55.

So Fibonacci # 8 + Fibonacci Number #9 = Fibonacci# 10

21 + 34 = 55

Answer:

Copper = x= 36.19

Step-by-step explanation:

The number of copper is unknown

Gold = 1/3

Silver = 1/5

Bronze =2/7

Copper = x

Total coins = 200

Gold = 1/3 of 200

= 1/3 × 200

= 200/3

= 66.67

Silver = 1/5 × 200

= 200/5

= 40

Bronze = 2/7 × 200

= 400/7

= 57.14

Total = gold + silver + bronze + copper

200 = 66.67 + 40 + 57.14 + x

200 = 163.81 + x

200 - 163.81 = x

x = 36.19

Copper = x= 36.19

Answer:

34

Step-by-step explanation:

let x = number of stamps ranu gives out and the number of stamps cathy receives

200 - x = 132 + x

combine like term s

200 - 132 = 2x

68 = 2x

x = 34

Answer:

log 14 22,344 = 3

where 14 is the base logarithm

Step-by-step explanation:

Here, we have the base of the log as 14 and the exponent or power as 3

So we have the general form as;

Given y = a^x

Log form is log a y = x

Applying this here, we have

log 14 22,344 = 3

Answer:

In A Premier League there are 20 soccer teams.

(a)In One Round How Many Games Are There?

20 choose 2 = 20C2 = 190

(b) If five of the teams represent one company, find the

number of ways pairs of teams representing different companies

can play the game.

So there are 4 companies, each having 5 teams.

4 companies choose 2 = 4C2 = 6 ways

Choose a team of the company that's, say, been in business the

longest.

5 teams choose 1 = 5C1 = 5 ways

Choose a team of the other company,

5 teams choose 1 = 5C1 = 5 ways

Answer 6*5*5 = 150 ways.

Answer:

The correct answer is B. Long-term.

Step-by-step explanation:

Since Zach has bought a car for $ 20,000 paying a down payment of $ 5,000 and monthly payments of $ 450 per month for 5 years, he will be paying a total of $ 32,000 for that car (5,000 + 450 x 12 x 5). Thus, the responsibility that Zach has incurred forces him to maintain his monthly payment obligation for 5 years, thus becoming a long term liability.

Step-by-step explanation:

Multiply all values (6.72, 5.78, and 12.7) together, then round to the nearest tenth.

Answer:

B. 3408pi

Step-by-step explanation:

formula volume of cone = 1/3 x pi x r x r x h

volume = 1/3 x pi x 12 x 12 x 71

= 3408pi

The volume of the cone is approximately 10,224 cubic units.

Option C is the correct answer.

It is a shape of a christmas tree where there is a base of radius r and a top point called the apex.

The volume of a cone is V = (1/3)πr²h,

We have,

The formula for the volume of a cone is V = (1/3)πr²h,

where r is the radius of the base of the cone, h is the height of the cone, and π is a constant approximately equal to 3.14.

Substituting the given values, we get:

V = (1/3)π(12²)(71)

V = (1/3)π(144)(71)

V = (1/3)(3.14)(144)(71)

V = 10,223.04

Rounding this answer to the nearest whole number, we get:

V ≈ 10,224

Therefore,

The volume of the cone is approximately 10,224 cubic units.

Step-by-step explanation:

According to the Question,

Thus , Mr. Cruz Consumes 50kwh in this month .

Given, the minimum charge for the first 10 kWh is $210 . & the succeeding consumed kWh costs $10 .

The Total Bill Of Mr. Cruz is ⇒ 210 + (50-10)×10 ⇔ 610$

Given:

Principal = $54,000

Time = 9 years

Rate of compound interest = 12% per annum.​

To find:

The compound interest.

Solution:

The formula for amount is:

[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]

Where, P is principal, r is the rate of interest in decimal, n is the number of time interest compounded and t is the number of years.

The interest is compounded annually, so [tex]n=1[/tex].

Substituting [tex]P=54000,\ t=9,\ n=1,\ r=0.12[/tex] in the above formula, we get

[tex]A=54000\left(1+\dfrac{0.12}{1}\right)^{1(9)}[/tex]

[tex]A=54000\left(1.12\right)^{9}[/tex]

[tex]A=149746.252902[/tex]

[tex]A\approx 149746.25[/tex]

The amount after 9 years is $149746.25.

Now, the compound interest is:

[tex]C.I.=A-P[/tex]

Where, C.I. is compound interest, A is amount and P is principal.

[tex]C.I.=149746.25-54000[/tex]

[tex]C.I.=95746.25[/tex]

Therefore, the compound interest is $95746.25.
