Each lapel on a suit jacket is in the shape of a triangle two of the three angles of each triangle measures 47 and 68 what is the measure of the third angle
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
Two of the three angles of each triangle measures 47 and 68We need to find the measure of the third angleIn 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°

Find two numbers whose difference is three when the larger number is decreased by three times the smaller number the result is -11
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.
what is the bionomial expansion of (x+y)^10
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].

-4x+7y=-14 slope intercept form
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.

Step-by-step explanation:
the difference of 2 2/3 and a number n divided by -2 1/5 equal to -13 / 33 find the value of n.
The value of n is [tex]1\frac{4}{5}[/tex].
Step-by-step explanation:
Given,
[tex](2\frac{2}{3}-n)/-2\frac{1}{5}=\frac{-13}{33}[/tex]
Writing the fractions in simplified form;
[tex](\frac{8}{3}-n)/\frac{-11}{5}=\frac{-13}{33}[/tex]
Taking LCM on left hand side;
[tex](\frac{8-3n}{3})/\frac{-11}{5}=\frac{-13}{33}\\[/tex]
[tex]\frac{8-3n}{3}*\frac{-5}{11}=\frac{-13}{33}\\\\\frac{-40+15n}{33}=\frac{-13}{33}\\\\[/tex]
Multiplying both sides by 33
[tex]33*(\frac{-40+15n}{33})=\frac{-13}{33}*33\\-40+15n=-13\\15n=-13+40\\15n=27[/tex]
Dividing both sides by 15
[tex]\frac{15n}{15}=\frac{27}{15}\\n=\frac{9}{5}\\n=1\frac{4}{5}[/tex]
The value of n is [tex]1\frac{4}{5}[/tex].

7. The startup cost for a boutique is $15,000, and each floral arrangement costs $17 for the boutique to make. If each arrangement is then sold for $25, after how many arrangements does the boutique break even?
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.
Which expression is equivalent to the value 16 ??
The equivalent expression to the value 16 is 2 × 8.
Explanation:The equivalent expression to the value 16 is 2 × 8.
This is because 16 can be written as the product of 2 and 8.
Therefore, the expression 2 × 8 is equivalent to the value 16.

Which expression is a difference of cubes?
O X6-6
O X6-8
O x8-6
O x8-8
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.
What are Expressions?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.

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, how much was the interest
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

Answer:
The library is 6 blocks away to the left of Alberto's place
Step-by-step explanation:
There's missing information on this question.
Suppose the point here is to find the distance.
A reflection across the y-axis makes the y-axis as the symmetry axis.
1) Each unit represents one block and they share the same y-coordinate (4).
2) We have to subtract the absolute value of x-coordinate.
