The measure of the third angle is 65°

Step-by-step explanation:

Each lapel on a suit jacket is in the shape of a triangle

In a triangle:

∵ The sum of the measures of the interior angles = 180°

∵ The measure of one angle = 47°

∵ The measure of other angle = 68°

- Substitute the measures of the two angles in the rule above

∴ 47 + 68 + measure 3rd angle = 180°

- Add the like terms

∴ 115 + measure 3rd angle = 180°

- Subtract 115 from both sides

∴ measure 3rd angle = 65°

The measure of the third angle is 65°

Answer:n=10, 5n=50

Step-by-step explanation:

an=50

n=50/a

n=50/5=10

5n=5×10=50

Answer:

Step-by-step explanation:

an = 50

a +(n-1)d = 50

5 + (n-1)*3 = 50

(n-1)*3 = 50 - 5 = 45

n-1 = 45/3

n-1 = 15

n=15+1 = 16

The equation in standard form is x + 2y = 8

Solution:

Given that we have to write the given equation in standard form

The equation given is:

[tex]y = \frac{-1}{2}x + 4[/tex]

The standard form of an equation is Ax + By = C

In this kind of equation, x and y are variables and A, B, and C are integers. When we shift the variable terms to the left side of the equation and everything else to the right side, we get the standard form.

[tex]y = \frac{-1}{2}x + 4\\\\y = \frac{-x}{2} + 4\\\\y =\frac{-x + 8}{2}\\\\2y = -x + 8[/tex]

Keep the variables on one side and constant term on other side

x + 2y = 8

Thus the above equation is in standard form of Ax + By = C

Answer:

Answer:

The two numbers are 10 and 7.

Step-by-step explanation:

Given:

The two numbers whose difference is three, when the larger number is decreased by three times the smaller number the result is -11.

Now, find the two numbers.

Let the larger number be [tex]x[/tex].

Let the smaller number be [tex]y[/tex].

As given, the two numbers whose difference is three:

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

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

So, the value of [tex]x=3+y[/tex].

According to question:

[tex]x-3y=-11[/tex]

Putting the value of [tex]x[/tex] we get:

[tex]3+y-3y=-11[/tex]

[tex]3-2y=-11[/tex]

Moving variables on one side and the number on the other we get:

[tex]3+11=2y[/tex]

[tex]14=2y[/tex]

Dividing both sides by 2 we get:

[tex]7=y[/tex]

The smaller number = 7.

Now, putting the value of [tex]y[/tex] in the equation [tex]x-y=3[/tex]:

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

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

Adding both sides by 7 we get:

[tex]x=10.[/tex]

The larger number = 10.

Therefore, the two numbers are 10 and 7.

Answer: The answer is below with explanations.

Step-by-step explanation:

In the binomial expansion of (x+y)^10, each term is calculated using the binomial coefficient formula. The expansion is [tex]x^10 + 10x^9y + 45x^8y^2 + 120x^7y^3 + 210x^6y^4 + 252x^5y^5 + 210x^4y^6 + 120x^3y^7 + 45x^2y^8 + 10xy^9 + y^10[/tex].

To expand the expression (x+y)^10 using the binomial theorem, we need to find the coefficients of each term. The general formula for the binomial expansion is: [tex](a+b)^n = C(n,0)a^n*b^0 + C(n,1)a^(n-1)*b^1 + ... + C(n,n)a^0*b^n[/tex], where C(n,k) represents the binomial coefficient. In this case, a=x, b=y, and n=10. Using the binomial coefficient formula, we can find the coefficients for each term:

[tex]C(10,0)*x^10*y^0 + C(10,1)*x^9*y^1 + C(10,2)*x^8*y^2 + ... + C(10,10)*x^0*y^10[/tex].

By calculating the binomial coefficients, the binomial expansion of (x+y)^10 is:

[tex]x^10 + 10x^9y + 45x^8y^2 + 120x^7y^3 + 210x^6y^4 + 252x^5y^5 + 210x^4y^6 + 120x^3y^7 + 45x^2y^8 + 10xy^9 + y^10[/tex].

Answer:

1875 arrangements

Step-by-step explanation:

Break-Even is the point when costs are equal to profit.

The cost is 15,000

We need to cover this up with the profit we get from sales.

Each arrangement is 17 (cost) and is sold for 25, so the profit from each arrangement is:

25 - 17 = 8

So, with each arrangement sale, we make profit of $8. How many of these we need to sell in order to break even (in order to make 15,000)??

We simply divide this amount (15,000) by the profit we make from each arrangement ($8), so that would be:

Number of Arrangements Needed to Break-Even = 15,000/8 = 1875

After 1875 arrangements, the boutique breaks even.

Answer:

y = 4/7x + 2 ( slop-intercept form)

Step-by-step explanation:

Answer:

The slope-intercept form of the given equation is,

[tex]y = \frac{4x}{7}-2[/tex]

Step-by-step explanation:

The given equation of the line is,

- 4x + 7y = - 14

Adding '4x' on both sides of the above equation, we get

   - 4x + 7y + 4x = - 14 + 4x

⇒ 7y = 4x - 14

Now, dividing both sides of the above equation by '7', we get

       7y ÷ 7 = (4x - 14) ÷ 7

[tex]\implies y = \frac{4x}{7}-\frac{14}{7}[/tex]

[tex]\implies y = \frac{4x}{7} - 2[/tex]

This is the required equation of the line in slope-intercept form.

If you're talking the equation [tex]\frac{5x-2}{3} =6[/tex], then:

[tex]\frac{5x-2}{3} =6[/tex]

[tex]5x-2=18[/tex]

[tex]x=4[/tex]

If you're talking about the equation [tex]5x-\frac{2}{3} =6[/tex], then:

[tex]5x-\frac{2}{3} =6[/tex]

[tex]5x = 6+\frac{2}{3}[/tex]

[tex]x=\frac{6}{5} +\frac{2}{15}[/tex]

[tex]x=\frac{18}{15} +\frac{2}{15}[/tex]

[tex]x=\frac{20}{15} = \frac{4}{3} = 1\frac{1}{3}[/tex]

Answer:

[tex]x^{6}[/tex] - 8

Step-by-step explanation:

A difference of cubes has the form

a³ - b³

Note that [tex]x^{6}[/tex] is a perfect cube, that is [tex](x^2)^{3}[/tex], but

[tex]x^{8}[/tex] is not

8 is a perfect cube, that is 2³ , but 6 is not

Thus

[tex]x^{6}[/tex] - 8 ← is a difference of cubes

= [tex](x^2)^{3}[/tex] - 2³

The expression which is a difference of cubes is B. x⁶ - 8.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Difference of cubes is termed for those expressions which can be written as the difference of terms which are cubes of some numbers or expressions.

Here,

From, x⁶ - 6, we cannot write 6 as a cube of any number.

So this is not the option.

From x⁶ - 8,

x⁶ can be written as (x²)³ using power of a power rule.

x⁶ - 8 = (x²)³ - (2)³

Hence the expression is x⁶ - 8.

Answer:

The interest that is obtained from that investment is $55.2

Step-by-step explanation:

If the balance at the end of eight years on an investment of $230 that has been invested at a rate of 3% is $285.20, so the principal of investment is $230 and the matured sum is $285.20.

Now, we know that Principal + Interest = Matured sum.

Hence, the interest that is obtained from that investment is $(285.2 - 230) = $55.2 (Answer)

Answer:

The interest credited after investment is $55.2

Step-by-step explanation:

Given as :

The investment principal amount = p = $230

The Amount after 8 years of investment = A = $285.20

The Time period for investment = 8 years

The rate of interest applied = r = 3%

Let The interest credited after investment = I

Now, According to question

From Compound Interest

Amount = Principal × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

And Interest = Amount - Principal

Or, I = A - p

Or, I = $285.20 - $230

∴   I = $55.2

So, The interest credited after investment = I = $55.2

Hence, The interest credited after investment is $55.2 Answer
