Roberta paid the amount of $47.19 for the curtains before the sales tax.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that equation editor A set of curtains normally sells for $58.99. Roberta used a coupon good for 20% off the regular price.
To determine the amount for the curtains before the sales tax
According to the given conditions, the solution would be as:
⇒ 58.99 × (1 - 20%)
⇒ 58.99 × (1 - 0.20)
Calculate the sum or difference and we get
⇒ 58.99 × 0.80
Apply the multiplication operation to get
⇒ 47.192
Round the number nearest to the hundredth,
⇒ 47.19
Therefore, Roberta paid the amount of $47.19 for the curtains before the sales tax.

find x if the base angles of an isosceles triangle are 47 degrees and 3x+14
Answer:
Step-by-step explanation:
The value of x is 11.
Given,
The base angles of an isosceles triangle are 47 degrees and 3x+14 degrees.
We need to find x.
What is an isosceles triangle?An isosceles triangle is a triangle that has two equal sides and two equal angles.
The equal angles are the base angles.
Find x.
We have,
Base angles: 47 degrees and (3x + 14) degrees
Since base angles are equal in an isosceles triangle.
We have,
47 = 3x + 14
47 - 14 = 3x
33 = 3x
x = 33/3 = 11
x = 11
Thus the value of x is 11.

6. Write the following cubes in expanded form:
(iii) (3a + 4b)³
8. Evaluate the following cubes using suitable Identities:
(ii) (999)³
Answer:
Step-by-step explanation:
we can use this algebraic identity:
[tex](a+b)^{3} =a^{3} +b^{3} +3ab(a+b)[/tex]
So,[tex](3a+4b)^{3} =(3a)^{3} +(4b)^{3}+3(3a)(4b)(3a+4b)[/tex]
=[tex](3a+4b)^{3} =27a^{3} +64b^{3} +36ab(3a+4b)[/tex]
=[tex](3a+4b)^{3} =27a^{3} +64b^{3} +108a^{2} b+144ab^{2}[/tex]
[tex](999)^{3}[/tex]=[tex](1000-1)^{3}[/tex]
Now, we can use the following identity:
[tex](a-b)^{3} =a^{3} -b^{3} -3ab(a-b)[/tex]
=[tex](1000-1)^{3} =1000^{3} -1^{3} -3(1000)(1)(1000-1)\\[/tex]
[tex](1000-1)^{3} =1,000,000,000-1-2,997,000[/tex]
[tex](1000-1)^{3} =997,002,999[/tex]

y is inversely proportional to the squre of X.given that Y=2 when X=6, find the calue of y when x=2
Answer:
y = 2/9
Step-by-step explanation:
y=x²
y=kx²
2= k(6)²
2= 36k
k= 1/18
The connecting formula is
y= 1/18x²
when y=? , x=2
therefore,
y= 1/18x²
y= 1/18(2)²
y= 1/18(4)
y= 2/9
Answer:
y = 18 when x = 2
Step-by-step explanation:
y ∝ x^2
y = k/x^2
Substituting 'y=2' and 'x=6' to get the value of k:
2 = k/6^2
2 = k/36
k = 36*2
= 72
Hence,
y = 72/x^2
Substituting 'x=2' to get the y-value:
y = 72/2^2
= 72/4
= 18
Hence,
when x =2, y = 18

find the value of :[5x+y+z][5x+y+z][5x+y+z]
Answer:
Step-by-step explanation:
(a + b + c)³ = a³ + b³ + c³ + 3a²b + 3a²c + 3ab² + 3cb² +3 ac² + 3bc² + 6abc
a = 5a ; b =y ; c = z
(5x + y + z)(5z + y + z )(5z + y +z) = (5x + y +z)³
= (5x)³ + y³ +z³ + 3(5x)²y + 3(5x)²z + 3(5x)*y² + 3*z*y² + 3*5x*z² + 3*y*z² + 6*5x*y*z
= 125x³ + y³ +z³ + 3*25x²y + 3*25x²*z + 15xy² + 3zy² + 15xz² + 3yz² + 35xyz
= 125x³ + y³ + z³ + 75x²y + 75x²z + 15xy² + 3zy² + 15xz² + 3yz² + 35xyz
