Answer:
38%
Step-by-step explanation:
Original price = $ 80
Price after reduction = $ 49.60
Reduction = 80 - 49.60 = $30.40
Percentage of decrease = [tex]\frac{reduction price}{original price}*100[/tex]
[tex]= \frac{30.40}{80}*100\\\\=\frac{3040}{80}[/tex]
= 38%
Answer:
38%
Step-by-step explanation:
80x0.62=49.60

At the museum, child admission is 5.80 and an adult is 9.20. On Saturday four times as many adults tickets as child tickets were sold, for a total sales of 1320.60. How many child tickets were sold that day?
Answer:
Number of child tickets sold = 31
Step-by-step explanation:
Let,
x be the number of child tickets sold
y be the number of adult tickets sold
According to given statement;
y = 4x Eqn 1
5.80x + 9.20y = 1320.60 Eqn 2
Putting y=4x in Eqn 2
5.80x + 9.20(4x) = 1320.60
5.80x + 36.80x = 1320.60
42.60x = 1320.60
Dividing both sides by 42.60
[tex]\frac{42.60x}{42.60}=\frac{1320.60}{42.60}\\x = 31[/tex]
Hence,
Number of child tickets sold = 31

Which functions graph is a translation of the graph of f(x)=x shifted 5 units to the right
a. g(x)=5x
b. g(x)=x-5
c.g(x)=x+5
d. g(x)=-5x
The function of the graph of a translation of the graph of f(x) = x shifted 5 units to the right is g(x) = x - 5, so option B is correct, the graph is also attached below.
What is function?When a function from one set to the other is utilized, every element of X receives precisely one element of Y. The function's domain and co-domain are collective terms used to refer to the sets X and Y, respectively.
Given:
f(x) = x, shifted 5 units to the right
A translation is a change in the graph's direction, either horizontally or vertically, parallel to the -axis.
Here, the translation is of 5 units,
Thus, the new function will be,
g(x) = x - 5

Points A(x,y) and B are on the same straight line.
The x-coordinate of B is three times the x-coordinate of A.
The y-coordinate of B is four times the y-coordinate of A.
What is the gradient of the line in terms of X and y?
Answer:
Solution,
Let the coordinates of A and B be (x, y) and (3x, 4y) respectively.
Then, the gradient (Slope) of AB is given by:
m = [tex]\frac{4y-y}{3x-x}[/tex]
or, m = [tex]\frac{3y}{2x}[/tex]
This is the required gradient of the line in terms of x and y.

Answer:
C = 56.52 in
A = 256.34 in²
Step-by-step explanation:
The figure is trying to show you that d=18 in, so r=9 in. The formulas for C and A are given, so you only need to put the numbers in the formula and do the arithmetic. Apparently, you're supposed to use 3.14 for π.
C = πd = (3.14)(18 in) = 56.52 in
A = πr² = (3.14)(9 in)² = (3.14)(81) in² = 254.34 in²

A discount voucher offering 15% off is used to pay a bill. After using the voucher, the bill is reduced to £36.72. How much was the bill before applying the voucher discount code.
Answer:
£91.80
Step-by-step explanation:
You first have to think, what is 15% of £36.72?
To do this, simply divide 100 by 3672, as we converted £36.72 to pence.
So 3672/100= 36.72. Then we multiply it by 15, which gives us 550.8
We then convert it back to pounds.
After you work that out you will get an answer of £55.08
We then add £55.08 to £36.72 and that will give us the answer, which is...
£91.80
OR
A quicker way is 15/100 of £36.72. Add the answer to £36.72= £91.80

Answer:
top one is 48 cm, bottom one is 17.5in.
Step-by-step explanation:
From what I understand, these shapes are increasing in size, so they will increase at a certain number. Our top one is rotated, but the 12cm is equivalent to the 3cm from the previous rectangle, thus making it greater by 4 times. To find x, we multiply 12cm by 4 to get 48cm. Same concept for the shapes on the bottom. Our 56in is equivalent to 8in, making it 7 times larger. Now, we multiply 2.5 by 7 to get 17.5in.

What is Arithmetic?The study and use of numbers, their relationships, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The word "arithmetic" (which derives from the Greek word "arithmos," "number") is frequently used to refer to the basic ideas in measuring, calculation, and number theory (specifically, the operations of addition, subtraction, multiplication, division, raising to powers, and root extraction).
As per the given data:
We are given the amount of dollar bills, quarters and pennies Rachel has.
Dollar bills = 1
Quarters = 3
Pennies = 2
1 Dollar bill = $1
1 Quarter = $0.25
1 Penny = $0.01
Total money that Rachel has
= 1 × (Dollar bill) + 3 × (Quarters) + 2 × (Pennies)
= 1 × ($1) + 3 × ($0.25) + 2 × ($0.01)
= 1 + 0.75 + 0.02
= $1.77
The total amount of money that Rachel has is $1.77.
Hence, The total amount of money that Rachel has is $1.77.

Find the measures of the interior
angles in a pentagon if the measure
of each consecutive angle is in the
ratio 9:6:10:8:12
Answer:
Angle 1 = 108°
Angle 2 = 72°
Angle 3 = 120°
Angle 4 = 96°
Angle 5 = 144°
Step-by-step explanation:
We need to find the measures of the interior angles in a pentagon if the measure of each consecutive angle is in the ratio 9:6:10:8:12.
Let x be the common ratio
So, we can write:
Angle 1 = 9x
Angle 2 = 6x
Angle 3 = 10x
Angle 4 = 8x
Angle 5 = 12x
We know that the sum of all angles of pentagon = 540
So, adding all angles and equal them to 540, we can find value of x
[tex]9x+6x+10x+8x+12x=540\\45x=540\\x=\frac{540}{45}\\x=12[/tex]
So, we get the value of x: x=12
Now, calculating the angles by putting x=12:
Angle 1 = 9x = 9(12) = 108°
Angle 2 = 6x = 6(12) = 72°
Angle 3 = 10x = 10(12) = 120°
Angle 4 = 8x = 8(12) = 96°
Angle 5 = 12x= 12(12) = 144°
(-2x^2 - 4x + 2) - (-6x + 2)

Answer:
1. x² – 11x + 24
2. a² + 5a + 6
Step-by-step explanation:
1. (x – 3)(x – 8) =?
Use the entities in the first bracket to multiply the second bracket. This is illustrated below:
(x – 3)(x – 8)
x (x – 8) – 3(x – 8)
x² – 8x – 3x + 24
x² – 11x + 24
Thus, the product of (x – 3)(x – 8) is
x² – 11x + 24
2. (a + 3)(a + 2) =?
Use the entities in the first bracket to multiply the second bracket. This is illustrated below:
a(a + 2) + 3(a + 2)
a² + 2a + 3a + 6
a² + 5a + 6
Thus, the product of (a + 3)(a + 2) is:
a² + 5a + 6
Factor 6x^9 - 15x^5
a.)2x^4(3x^5-7x)
b.)3x^4(2x^5-5x)
c.)6x^4(x^5-2x)
d.)3x^5(2x^4-5)
Factor 3x^5 out of 6x^9 − 15x^5.
3x^5 (2x^4 − 5)
The factor equivalent to 10/12
Answer:
Step-by-step explanation:
So, here are some examples: 56 is equivalent to 1012 because 5 x 12 = 6 x 10 = 60. 1518 is equivalent to 1012 because 15 x 12 = 18 x 10 = 180. 2024 is equivalent to 1012 because 20 x 12 = 24 x 10 = 240.
