Sean pays £10 for 24 chocolate bars. He sells all 24 chocolate bars for 50p each.
Work out Sean's percentage profit.
Answers
Answer:
the percentage profit is 20%
Step-by-step explanation:
Given that
Sean paid £10 for 24 chocolate bars
He sold all 24 chocolate bars for 50p each
we need to find out the percentage profit
Since he paid £10 and sale value is (24 × 0.50) i.e. £12

= (£12 - £10) ÷ (£10)
= 20%
Hence, the percentage profit is 20%

Find the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters. Round your answer to the nearest tenth.
Answers
Answer: 565.3 cubic cm
Step-by-step explanation:
V= 1/3Bh
V= 1/3π r^2h
= 1/3 π (6 cm) ^2 (15 cm)
= 1/3 π (36 cm squared) (15 cm)
= 180π cubic cm
about 565.2 cubic cm
π is about 3.14
The value of the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters is,
⇒ 565.2 cubic cm
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
In cone,
Radius = 6 cm
Height = 15 cm
Now, We know that;
Volume of cone is,
V = 1/3π r²h
Substitute all the values we get;
V = 1/3 π (6 cm)² (15 cm)
V = 1/3 π (36) (15)
V = 180π
V = 565.2 cubic cm
Thus, The value of the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters is,
⇒ 565.2 cubic cm

Answers
Given:
The matrix statements in the options.
To find:
The answer choice that show the commutative property does not hold for matrix multiplication.
Solution:
We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then
[tex]AB\neq BA[/tex]
Let us assume,
[tex]A=\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\text{ and }B=\begin{bmatrix}1&3\\8&5\end{bmatrix}[/tex]
According to the above property of the matrix, we get
[tex]\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\begin{bmatrix}1&3\\8&5\end{bmatrix}\neq \begin{bmatrix}1&3\\8&5\end{bmatrix}\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}[/tex]
Therefore, the correct option is B.

From the figure
We can see a rectangle and a triangle
The area of the rectangle is
Area= L*W
Area= 13*5
Area= 65 in^2
Area of the triangle
Area= 1/2b*h
Area= 1/2*4*5
Area= 2*5
Area= 10 in^2
Hence the area of the composite figure is
Area= 65+10
Area= 75 in^2
