the owner of a pet shop buys budgie bells in packs of 30 bells. she pays 12p per bell. She sells 3/5 of the bells for 50p each and the rest for 40p each. How much profit does she make on the whole pack of budgie bells?
Answer: 1020p
Step-by-step explanation:
The total cost of the bells will be:
= 12p × 30 = 360p
She sells 3/5 of the bells for 50p each. This will be:
= (3/5 × 30) × 50
= 18 × 50p
= 900p
She sells the remaining 2/5 for 40p each. This will be:
= (2/5 × 30) × 40
= 12 × 40
= 480p
Then, total revenue will be:
= 900p + 480p
= 1380p
Profit = Revenue - Cost
= 1380p - 360p
= 1020p

What is a number that when you multiply it by 0.9 and
subtract 6.3 from the product, you get 4.5?
The number that when you multiply it by 0.9 and subtract 6.3 from the product, you get 4.5 is 12.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let the number be x.
According to the problem, we have:
0.9x - 6.3 = 4.5
Adding 6.3 to both sides, we get:
0.9x = 10.8
Dividing both sides by 0.9, we get:
x = 12
Therefore,
The number we're looking for is x = 12.

The side of a box has length x feet, and another side has length (x-7) feet. What value of a would produce an area of 18 square feet?
Answer:
x=9
Step-by-step explanation:
(9-7) = 2
9 times 2 = 18 square feet
Value of x is 9 , -2
Given that;
Length of box = x feet
Width of box = (x - 7) feet
Area of box = 18 square feet
Find:
Value of x
Computation:
Area of rectangle = Length × Width
Area of rectangular box = x × (x - 7)
x² - 7x = 18
x² - 7x - 18 = 0
Using factorisation;
x² - 7x - 18 = 0
x² - (9 - 2)x - 18 = 0
x² - 9x + 2x - 18 = 0
x(x - 9) + 2(x - 9) = 0
(x - 9)(x + 2) = 0
So,
x = 9, x = -2

The equation y = 1125(1.034)" can be used to approximate the number of cell phone users
who live in a certain city over time, where a represents the number of years after 2000.
Which of the following statements is true?
A
the rate of growth is 34%
B
there were 1125 cell phone users in 2000.
С
the rate of decay is 3.4%
D
In the year 2005, there were more than 1350 cell phone users.
Answer: B
there were 1125 cell phone users in 2000.
Step-by-step explanation:
The initial number of cell phone users is the front coefficient that is then multiplied by the growth factor.
So the initial number of cell phone users in 2000 was 1125.
This line segment will be dilated with the point of dilation at (4,1) and scale factor of 2. What is the x-coordinate of one of the the end point of the dilated segment
Answer:
8Step-by-step explanation:
If a coordinate point (x, y) is dilated by a factor k, then the resulting coordinate will be (kx, ky)
Given the coordinate (4,1), if this coordinate is dilated by a factor of 2 then the new coordinate points will be at (2(4), 2(1))
New point = (8, 2)
Hence x-coordinate of one of the the end point of the dilated segment is 8

What is parallelogram?A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.
A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.
Given Jack is in shape of parallelogram,
height of crank of jack from ground = 5 inches
to find the distance from ground to top of jack
since crank is at centre of jack and bottom to top of jack makes the diagonal of parallelogram,
distance from crank to top of jack is 5 inches,
because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.
total length from ground is 5 + 5 = 10 inches
Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

The chess clubcab have at most 36 members. The are 3 times as many boys as girls in the chess club. Which inequality could be used to determine the possible number of girls, x, in the chess club?
Answer:
The number of girls is at most 9 girls
y ≤ 9
Step-by-step explanation:
The chess clubcab have at most 36 members.
At most means : Less than or equal to 36 members and it is represented by the inequality = ≤
The are 3 times as many boys as girls in the chess club.
Boys = x
Girls = y
Hence,
x = 3y
Which inequality could be used to determine the possible number of girls, x, in the chess club?
Therefore,

Answer:
0.29 or 29 percent I put it on god
Step-by-step explanation:
The percentage of people attending supported the home team is 29%.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given, 2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team.
From the general formula of percentage:
percentage = value/ total value * 100
Since, Out of 2400 only 696 supported the home team
thus,
Percentage = 696/2400*100
Percentage = 29%
Therefore, 29% percentage of people attending supported the home team.
