Answer:

x = 6[tex]\sqrt{5}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 12² = 18²

x² + 144 = 324 ( subtract 144 from both sides )

x² = 180 ( take the square root of both sides )

x = [tex]\sqrt{180}[/tex]

  = [tex]\sqrt{36(5)}[/tex]

   = [tex]\sqrt{36}[/tex] × [tex]\sqrt{5}[/tex]

   = 6[tex]\sqrt{5}[/tex] ← exact value

Step-by-step explanation:

Answer:

You can’t add both terms because the coefficients are multiplying different variables. It’s like trying to add apples and oranges together. They are two different things. So is this situation, variables b and m are two different things. Therefore you can’t add them together. This means that you can’t simplify the expression any further. This also means that you can’t combine like terms, because the two terms are unalike.

the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.

We need to find the distance between two points which is the hypotenuse of the triangle:

(8, 7) and (6, 3)

It can be calculated using distance formula:

D = √ (x₂ - x₁)² + (y₂ - y₁)²

Substituting the values in the formula, we get that:

D = √ (6 - 8)² + (3 - 7)²

D = √ ( - 2 )² + ( - 4 )²

D = √ 4 + 16

D = √ 20

D = 2 √ 5 units

Therefore, we get that, the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.

Answer:

x = - 3

Step-by-step explanation:

Given

3(x - 6) + 6 = 5x - 6 ← distribute and simplify left side

3x - 18 + 6 = 5x - 6

3x - 12 = 5x - 6 ( subtract 5x from both sides )

- 2x - 12 = - 6 ( add 12 to both sides )

- 2x = 6 ( divide both sides by - 2 )

x = - 3

Step-by-step explanation:

Given that:

Total maximum amount that the owner wishes to spend = $20000

Average price of each car = $4000

To find:

How many cars that the owner can expect to buy?

Solution:

Total number of cars that the owner can expect to buy can be found by dividing the total money available with the owner with the average price of each car.

i.e.

[tex]\text{Number of cars expected to be bought} = \dfrac{\text{Total money available with the owner}}{\text{Average Price of car}}[/tex]

We have the following values as given in the question statement:

Total money available = $20000

Average price of car = $4000

Therefore, the answer is:

[tex]\text{Number of cars expected to be bought} = \dfrac{20000}{4000} = \bold{5}[/tex]

The owner can expect to buy 5 number of cars.

they take 6 hours  to paint the garage if the two of you paint together.

It will take you 10 hours to paint your garage

it will take your brother 15 hours to paint your garage.

How long will it take to paint the garage if the two of you paint together

Total work = LCM of 10 and 15 = 30 units

now , it will take 10 hours to paint the garage

therefore it one hour efficiency = 30/10 =3 units

similarly your brother take 15 hours to apint the garage

therefore brother one hour efficiency = 30/15 = 2 units

so total one hour efficiency is 5 units

and total work is 30 units and their one hour efficiency is 5 units

therefore they complete the work in 30 /5 = 6 hour

Hence they take 6 hours  to paint the garage if the two of you paint together.

Answer:

Step-by-step explanation:

Answer:

-25.1m - 9.1

Step-by-step explanation:

Well all the angles in a triangle add up too 180º and this triangle is obviously a equilateral triangle (all sides are same) BUT as you see the other people saying X = 60º notice that it says 2 xº meaning that it is X x 2 so 60º is actually wrong :).

If it is X is 60º (since the 3 angles add together since it’s equilateral) then that would be 2 x 60º = 120º times 3 WHICH IS NOT 180.I think U get what I mean now,it’s 2 Xº; so X is 30 because 30 x 2 = 60º and 60 x 3 = 180º!

So Da Answer is X = 30º

Hope this helped :)

Anil Kumar should pay a compound amount of Rs. 23,397.12 at the end of 2 years.

Compound interest is a method of calculating interest where the interest earned is added to the principal amount, and the resulting sum becomes the new principal for the next period's interest calculation. This process is repeated until the end of the investment period.

The formula to calculate the compound interest is:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

Where,

A = Amount after the given time

P = Principal amount (initial investment)

r = Annual interest rate (as a decimal)

n = Number of times the interest is compounded per year

t = Time duration for which the interest is calculated (in years)

In this case, Anil Kumar took a loan of Rs. 20,000 from a bank at the rate of 8% per annum, compounded half-yearly, for 2 years. Therefore, we can plug in the values as follows:

P = Rs. 20,000

r = 8% per annum = 0.08 (as a decimal)

n = 2 (since the interest is compounded half-yearly)

t = 2 years

Now, we can calculate the compound amount using the above formula:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

[tex]A = 20,000(1 + 0.08/2)^(^4^)[/tex]

[tex]A = 20,000(1 + 0.04)^4[/tex]

[tex]A = 20,000(1.04)^4[/tex]

[tex]A = 23397.1712[/tex]

Therefore, Anil Kumar should pay a compound amount of Rs. 23,397.123 at the end of 2 years.

Hello!

[tex]\large\boxed{k = 10^{o}}[/tex]

When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:

m∠YZX + m∠ZXY ≅ m∠MYZ

(4k + 5)° + (6k + 10)° = 115°

Combine like terms:

10k + 15 = 115°

Subtract 15 from both sides:

10k = 100°

Divide both sides by 10:

k = 10°

Answer:

k=10

Step-by-step explanation:

First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.

Second you would set the equations equal to 115

4k+5+6k+10=115

Then you would combine the like terms

10k+15=115

next you would subtract the 15 from both sides

10k=100

then you divide by 10

k=10

6 weeks from now, you will have $215 in your bank account

The given parameters are:

b = 60 + (20+6)w

When the account balance is $215, we have

60 + (20+6)w = 215

Subtract 60 from both sides

(20+6)w = 155

This gives

26w = 155

Divide both sides by 26

w = 5.96

Approximate

w = 6

Hence, 6 weeks from now, you will have $215 in your bank account

Answer:

The inequation 6x ≥ 8x - 4 can be used to find the solution.

The solution is x ≤ 2

Step-by-step explanation:

In math, 'at least' represents greater or equal than (which is the inequation simbol ≥)

If x represents the number then six times a number is the multiplication of x by 6, and four less than eight times the number can be written as: 8x -4

6x ≥ 8x - 4

Solving the inequation;

Substracting 6x each side:

0 ≥ 8x - 6x -4

Suming 4 each side

4 ≥ 2x

Dividing by 2 each side

2 ≥ x

2 greater or equal than x is the same as:
