The purchase price of a diamond ring increases by £20 when the rate of VAT is increased from 12% to 20%. Find the original purchase price of the ring
The original price of the ring is £250.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
Given that, the purchase price of a diamond ring increases by £20 when the rate of VAT is increased from 12% to 20%.
Let the original price of the ring be x, then according to question,
120% of x - 112% of x = 20
1.2x - 1.12x = 20
0.08x = 20
x = 20/0.08
x = 250
Hence, The original price of the ring is £250.

Find all real numbers x such that
(3^x - 27)^3 + (27x - 3)^3 = (3x + 27x - 30)^3
All the real numbers x in the expression such that (3x - 27)³ + (27x - 3)³ = (3x + 27x - 30) is x = 1 .
In the question ,
it is given that the expression is
(3x - 27)³ + (27x - 3)³ = (3x + 27x - 30)
By using the identity a³ + b³ [tex]=[/tex] (a + b)(a² - ab + b² )
we get ,
[(3x - 27 + 27x - 3)] × [(3x - 27)² - (3x - 27)(27x - 3) + (27x - 3)² ] = 30x - 30
(30x - 30)×[(3(x - 9))² - (3(x - 9) × 3(9x - 1)) + (3(9x - 1))²] = 30x -30
using the identity (a-b)² [tex]=[/tex] a² -ab + b²
(30x - 30) × [9( x² - 18x + 81) - (9(9x² - 82x + 9)) + (9(81x² - 18x + 1)) = 30x-30
9(30x - 30)×[x² - 18x + 81 - 9x² + 82x - 9 + 81x² - 18x + 1] = 30x - 30
270×(x - 1)×[ 73x² + 46x + 73] = 30(x - 1)
taking (x-1) terms to LHS ,
we get
(270 - 30)×(x - 1)[ 73x² + 46x + 73 ] = 0
(240) (x - 1) [ 73x² + 46x + 73 ] = 0 ....because 270-30 = 240
Dividing both sides by 240
we get ,
(x - 1) [73x² + 46x + 73] = 0
So , either x - 1 = 0 or 73x² + 46x + 73 = 0
on solving 73x² + 46x + 73 = 0
we get the discriminant of 73x² + 46x + 73 a negative number , so it cannot have real root .
hence x -1 = 0
x = 1
Therefore , the only real solution is x = 1 .

In a school of 320 children, 45% of the children speak a language other
than English at home.
(i) Calculate the number of children in the school who speak a
language other than English at home.
(ii) Of the children who speak a language other than English at home,
24 speak Polish. Write the number of children who speak Polish as
a fraction of the number of children who speak a language other than English at home.
Give your answer in its simplest form.
The number of children in the school who speak a language other than English at home is 144.
The fraction of children who speak Polish is 1/6.
How many children speak a language other than English?Percentage is the ratio of a quantity expressed as a number out of 100. Percentage is a measure of frequency. The sign that is used to represent percentage is %.
Number of children in the school who speak a language other than English at home = Percentage of the students who speak a language other than English x number of children
Number of children in the school who speak a language other than English at home = 45% x 320
Number of children in the school who speak a language other than English at home = 0.45 x 320 = 144
A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.
Fraction of the students who speak Polish = number of students that speak Polish / total number of students who speak a language other than English.
Fraction of the students who speak Polish = 24 / 144 = 1/6.

PROVE IT!! SHOW YOUR WORK!!!!!
A) $3 B) $4 C) $5.50 D) $6
Answer:
$3
Step-by-step explanation:
Total of all = $19.50
3 Card holders total = $7.50
4 Baseball card total = ?
We know that 19.50 is the sum of the holders and cards together so we subtract $7.50 from $ 19.50.
$19.50-$7.50=$12 for ALL four baseball cards
We know that 4 baseball cards are $12, but if we DIVIDE 12 by four, we get the individual price per card.

7z-4=12+3z
Answer:
z = 4
Step-by-step explanation:
7z - 4 = 12 + 3z
1) We want to first move the z values to one side of the equation. This means we would subtract 3z from both sides to move it to the left side. This would give us 4z - 4 = 12.
2) We then want to isolate the z value. This means we want to move the -4 to the right side. We would add 4 to both sides and get 4z = 16.
3) We can then divide both sides by 4 and get the value for z.
This gives us z = 4.
Fine the values of x and y.
Answer:
x = 55
y = 20
Step-by-step explanation:
Angles on a straight line sum to 180°.
Finding x
⇒ 75° + (2x - 5)° = 180°
⇒ 75 + 2x - 5 = 180
⇒ 2x + 70 = 180
⇒ 2x + 70 - 70 = 180 - 70
⇒ 2x = 110
⇒ 2x ÷ 2 = 110 ÷ 2
⇒ x = 55
Finding y
⇒ 75° + (4y + 25)° = 180°
⇒ 75 + 4y + 25 = 180
⇒ 4y + 100 = 180
⇒ 4y + 100 - 100 = 180 - 100
⇒ 4y = 80
⇒ 4y ÷ 4 = 80 ÷ 4

Answer: The answer to this question is $90.
Step-by-step explanation:
The Simple interest is $90.
What is Simple Interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
For example, if you borrowed $100 from a friend and agree to repay it with 5% interest, then the amount of interest you would pay would just be 5% of 100: $100(0.05) = $5.
Given:
P= 1500
R = 12%
T= 6 month = 1/2 year
Using, formula of Simple Interest
I = P x R x T /100
I = 1500 x 12 x 1/ 2x100
I = 18000/200
I = 90

Explain on your work paper how you made this conclusion. Invalid
Nice work on selecting "invalid" as the correct answer.
The reason why this argument is invalid is because the 'x' could be in circle B or could be outside circle B. There's simply not enough information.
The venn diagram would either be (A) or (D).
The only information we know is that Fred is does not live in San Francisco, so the 'x' will not be placed inside circle A.
Ignore any diagram where x is on the edge of a circle. That isn't allowed in venn diagrams because a person is either in San Francisco, or they aren't (same goes with California). We can't have blurry boundaries like that. This means venn diagrams (B) and (C) are nonsensical.

Base = 4(4) = 16
Height = 7(4) = 28
Subbing this values into our formula for the area of a triangle, and we have:

The solution set for the inequality is (-3, 3)
How to solve the absolute value inequality?Here we have the absolute value inequality
|2x| - 6 < 0
To solve this, we need to isolate the variable, which in this case is x.
Adding 6 in both sides we get:
|2x| -6 + 6 < 0 + 6
|2x| < 6
This can be decomposed in the inequality:
-6 < 2x < 6
Now to competely solve the inequality, we will divide both sides by 2, so we get:

-3 < x < 3
