What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Amy earned £18400 and her total loan repayments were £5600. Hence:
Ratio of repayments to earnings = £5600 / £18400 = 7/23

In engineering, the modulus of elasticity is a way to measure how much an object deforms along an axis when opposing forces are applied among that axis. The formula can be expressed as E=(F2−F1)L0(δ2−δ1)A , where E is the modulus of elasticity, F is the axial force, δ is a deformation measure, L0 is the original length of the object, and A is the cross-sectional area.
Step-by-step explanation:
Consider an engineering material of initial length Lo, Area (A), Modulus of elasticity (E) and applied a force P due to which change in the length of the material is δ2 from it’s original length (Lo)
Initial length of the material is Lo. Hence, at time t = 0 when no force applied on the material the length of the material will not change (i.e., at time t=0, δ1 = 0)
Modulus of elasticity of the material:
[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]
Area of the material:
[tex]E=\frac{P \cdot L_{o}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]
[tex]A=\frac{P \cdot L_{o}}{E\left[\delta_{2}-\delta_{1}\right]}[/tex]
Length of the material:
[tex]E=\frac{P \cdot L_{0}}{A\left[\delta_{2}-\delta_{1}\right]}[/tex]
[tex]L_{0}=\frac{E \cdot A\left[\delta_{2}-\delta_{1}\right]}{P}[/tex]

1. Andre bought a new bag of cat food. The next day, he opened it to feed his cat. The
graph shows how many ounces were left in the bag on the days after it was bought.
a. How many ounces of food were in
the bag 12 days after Andre bought
it?
b. How many days did it take for the
bag to contain 16 ounces of food?
c. How much did the bag weigh before
it was opened?
d. About how many days did it take for
the bag to be empty?
ounces of cat food
Using a linear function, it is found that:
a) 36 ounces of food were there after 12 days.
b) It took 24 days for the bag to contain 16 ounces of food.
c) The bag weighed 56 ounces before it was opened.
d) It took about 33 days for the bag to be empty.
What is the definition of a linear function?A linear function is defined according to the following rule:
y = mx + b
In which:
m is the slope of the function, also called the rate of change of the function, given by the change in y divided by the change in x.b is the y-intercept of the function, which is the the value of y when the function crosses the x-axis(x = 0).From the graph of the function, we have that:
The intercept is of b = 56.The slope is of m = -40/24 = -1.6667, as in 24 days, the amount of food decayed from 56 ounces to 16 ounces, that is, it decayed 40 ounces.Hence the function for the amount of food after t days is given by:
A(t) = 56 - 1.6667t.
After 12 days, the amount is given by:
A(12) = 56 - 1.6667(12) = 36 ounces.
From the graph, we have that:
It took 24 days for the bag to contain 16 ounces of food.The bag weighed 56 ounces before it was opened. (y-intercept of the function = initial value).It took about 33 days for the bag to be empty. (x-intercept of the function).What is the missing information?The graph of the function is missing, and is given at the end of the answer.

I am sorry thats a lot to type out.
Step-by-step explanation:
I will say that to know if its rational, you have to see if the integer can be written in a fraction (like 0.333, 89/10, -4, 0)
Answer:
Whole numbers: 3, [tex]\sqrt{4}[/tex], [tex]\frac{49}{7}[/tex], zero
Integer but not whole: -100, -34, -4, -[tex]\frac{8}{4}[/tex]
Rational number: 9.23456, [tex]\frac{1}{2}[/tex], [tex]\frac{89}{10}[/tex], 0.333_
Irrational number: [tex]\pi[/tex], 0.456783_, [tex]\sqrt{8}[/tex]
Step-by-step explanation:
Whole number is any number that does not have a decimal and is not negative. [tex]\sqrt{4}[/tex] = 2. [tex]\frac{49}{7}[/tex] = 7. 0 is not negative and does not have a decimal so it is also a whole number.
Integers are any number that does not have a decimal and can be both positive or negative. -[tex]\frac{8}{4}[/tex] = -2.
A rational number can have a decimal but the decimal digits must terminate or the digit must repeat. [tex]\frac{1}{2}[/tex] is 0.5. [tex]\frac{89}{10}[/tex] is 8.9 and 0.333_ repeats the digit 3 so it is rational.
An irrational number can have a decimal and the decimal digits must list on forever or not repeat. [tex]\pi[/tex] is naturally an irrational number as it does not repeat and it spreads on forever. 0.456783_ does not repeat and goes on forever due to the dash at the back. [tex]\sqrt{8}[/tex] is also not rational.
A bin in the gym holds 40 balls, which are a mix of
basketballs, soccer balls, and dodgeballs. The ratio
of basketballs to soccer balls is 3:1. The ratio of
soccer balls to dodgeballs is 1:4. How many basket-
balls are in the bin?
The number of marbles in the bag is illustrated using proportions.
There are 15 basketballs in the bin
The given parameters are:
[tex]\mathbf{B : S = 3 : 1}[/tex]
[tex]\mathbf{S : D = 1 : 4}[/tex]
[tex]\mathbf{n = 40}[/tex]
First, we combine the ratios
[tex]\mathbf{B:S:D = 3:1:4}[/tex]
The number of basketballs is calculated as follows:
[tex]\mathbf{Basketball= \frac{B}{B + S + D} \times n}}[/tex]
So, we have:
[tex]\mathbf{Basketball= \frac{3}{3 + 1 + 4} \times 40}[/tex]
[tex]\mathbf{Basketball= \frac{3}{8} \times 40}[/tex]
[tex]\mathbf{Basketball= 3 \times 5}[/tex]
[tex]\mathbf{Basketball= 15}[/tex]
Hence, there are 15 basketballs in the bin

A shop sells cereal in boxes A, B and C. Box A 500 g for $1.73 Box B 750 g for $2.60 Box C 1.25 kg for $4.35. which box is the best value?
Answer:
Box C
Step-by-step explanation:
First switch the box that's in kilograms into grams. One kilogram=1000 grams. So box C is 1250 grams.
Next divide the amount in each box by the cost of each box.
Box A 500/173=2.89
Box B 750/260=2.88
Box C 1250/435=2.87
So, since box C has the lowest amount when divided, that box has the best value.

120% of x is 96. What is x?
Answer:
Step-by-step explanation:
You can do this using a small equation.
120% x = 96 Change 120% to a decimal
120/100 * x = 96 Multiply by 100
120x = 96 * 100
120x = 9600 Divide by 120
x = 9600/120
x = 80
Look what you got. 20% more than 80 is 96. x is smaller than 96.
If you take 20/100 * 80 = 16
if you add 16 to 80, you get 96
Answer:
x = 80
Step-by-step explanation:
120 % of x = 96
or, 120/ 100 × x = 96 change percentage to 100 and devide
or, 6 / 5 × x = 96
or, 6x / 5 =96. multiply 6 and x
or, 6x = 96 × 5. change devide sign to multiply
or, 6x = 480. multiply
or, x = 480 / 6. change multiply sign to devide
therefore, x = 80

Step-by-step explanation:
Step 1: Subtract 5x from both sides.
3x + 4 - 5x = 5x + 28 - 5x
-2x + 4 = 28
Step 2: Subtract 4 from both sides.
-2x + 4 - 4 = 28 - 4
-2x = 24
Divide both sides by -2.
-2x/-2 = 24/-2

When a line segment is bisected into 2 halves, the two halves are equal. In this case, when AB is bisected by CD, AE and BE would be equal and each point on CD should be equidistant from point A and point B. Therefore, AC = AB.
Which expression represents the volume, in cubic
units, of the composite figure?
O (8)(6)6) + (8)(6)(4)
O (8)(6)(10) + (8)(6)(4)
O (8X6)\4)-(ex6)X6)
O (8X6)(4) –eX6)10)
Given:
The composite figure.
To find:
The volume of the given composite figure.
Solution:
Given composite figure contains a cuboid and a pyramid.
Length, breadth and height of the cuboid are 8, 6 and 4 respectively.
Volume of a cuboid is
[tex]V_1=length\times breadth\times height[/tex]
[tex]V_1=(8)(6)(4)[/tex]
Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.
Height of pyramid = 10 - 4 = 6
Volume of a pyramid is
[tex]V_2=\dfrac{1}{3}\times length\times breadth\times height[/tex]
[tex]V_2=(\dfrac{1}{3})(8)(6)(6)[/tex]
The volume of composite figure is
[tex]V=V_1+V_2[/tex]
[tex]V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)[/tex]
It can be written as
[tex]V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)[/tex]
Therefore, the correct option is A.
