A pounds of apples and b pounds of plums were packed into n boxes. How many pounds of fruit are there in each box?
Answers
Answer:
(a + b) / n
Step-by-step explanation:
Pounds of apple in box = a
Pounds of plum in box = b
Number of boxes used in packing = n
The amount fruit in pounds that are in each box :
Total pound of fruits / number of boxes used
Total pounds of fruit = a + b
Number of boxes used = n
Hence, we have ;
(a + b) / n

What is an expression?An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.Many authors make a distinction between an expression and a formula, with the former designating a mathematical object and the latter a claim about such objects.Solution -The piece of rope is 1m long.
Carter divided the ropes into three equal parts by tying up the knot.
1 meter = 3 foot.
Therefore, divide 3 by 3.
[tex]\frac{3}{3} =1[/tex] foot.
Therefore, each section is 1 foot long.

Work out the area of the trapezium ABDE.
A
В.
7.5 cm
2.5 cm
С
5 cm
E
Answers
Answer:
Area = 50 cm²
Step-by-step explanation:
Area of a trapezium ABDE = ½(a + b)h
where,
a = BD = 2.5 cm
b = AE = 7.5 cm
h = DE = ?
We need to find DE ti be able to calculate the area.
DE = CE - CD
DE = CE - 5
Since ∆ACE is similar to ∆BCD, therefore:
AE/BD = CE/CD
Plug in the values
7.5/2.5 = CE/5
Cross multiply
CE*2.5 = 7.5*5
CE*2.5 = 37.5
Divide both side any 2.5
CE = 37.5/2.5
CE = 15
Thus, DE = CE - 5 = 15 - 5
DE = 10
✅Area of trapezium = ½(BD + AE)DE
= ½(2.5 + 7.5)*10
= ½(10)10
= 50 cm²

Which value, to the nearest tenth, is the smallest solution of f(x) = g(x) if f(x) = ln(x + 5) – 1 and g(x) = x3 – 2x + 1?
Answers
Answer:
There are two possibilities of determine which solution is the smallest one:
(i) The smallest solution is the value of [tex]x[/tex] has the smallest distance with respect to origin: [tex](x_{2},y_{2}) = (0.18,0)[/tex]
(ii) The smallest solution is the most negative value: [tex](x_{1},y_{1}) = (-1.577,0)[/tex]
Step-by-step explanation:
Let [tex]f(x) = g(x)[/tex], [tex]f(x) = \ln (x+5)-1[/tex] and [tex]g(x) = x^{3}-2\cdot x + 1[/tex], then we have the following implicit equation:
[tex]\ln (x+5)-x^{3}+2\cdot x -2 = 0[/tex] (1)
This equation cannot be solved by analytical means. There are two different strategies to solve this expression: (i) Numerical methods, (ii) Graphical methods. We decide to use the second method:
Let suppose that we use this function [tex]h(x) = \ln (x+5) -x^{3}+2\cdot x - 2[/tex]. By the help of a graphing tool, we find the smallest solution such that [tex]h(x) = 0[/tex]. There are three possible solutions: [tex](x_{1},y_{1}) = (-1.577,0)[/tex], [tex](x_{2},y_{2}) = (0.18,0)[/tex], [tex](x_{3}, y_{3}) = (1.376, 0)[/tex]
There are two possibilities of determine which solution is the smallest one:
(i) The smallest solution is the value of [tex]x[/tex] has the smallest distance with respect to origin: [tex](x_{2},y_{2}) = (0.18,0)[/tex]
(ii) The smallest solution is the most negative value: [tex](x_{1},y_{1}) = (-1.577,0)[/tex]
The smallest smallest solution of f(x) = g(x) will be [tex]\rm \left(-1.577,0.223\right)[/tex]
What exactly is a function?A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.
Given functions;
f(x) = ln(x + 5) – 1
g(x) = x³ – 2x + 1
After graphing both the function, we get the three solutions of the given equation,
[tex]\rm \left(-1.577,0.223\right)[/tex]
[tex]\left(0.18,0.645\right)[/tex]
[tex]\left(1.376,0.853\right)[/tex]
Hence,the smallest smallest solution of f(x) = g(x) will be [tex]\rm \left(-1.577,0.223\right)[/tex]

Henry and Gavin win some money and share it in the ratio 5:3. Henry gets £14 more than Gavin. How much did they get altogether?
Answers
Answer:
Total amount = £56
Step-by-step explanation:
Let Henry and Gavin be H & G respectively.
Let Henry's and Gavin's share be x.
Given the following data;
Ratio of H to G = 5:3
Henry = G + £14
Translating the word problem into an algebraic expression, we have;
5x = 3x + 14
5x - 3x = 14
2x = 14
x = 14/2
x = £7
Next, we determine the amount earned by Gavin;
Gavin = 3x
Gavin = 3*7
Gavin = £21
For Henry;
Henry = G + £14
Henry = £21 + £14
Henry = £35
Now, to find the total amount earned by Henry and Gavin.
Total amount = H + G
Total amount = 35 + 21
Total amount = £56
