Tom weighs 5kg more than Harry. Harry weighs 3kg more than Freddie who, in turn weighs
2 kg less than Alfie. What is the difference, in kilograms, between Tom and Alfie?
Answers
The difference between Tom and Alfie is 1 kg
Let's call the weight of Tom T, the weight of Harry H, the weight of Freddie F, and the weight of Alfie A. We are given that T = H + 5, H = F + 3, and F = A - 2.
Substituting the second and third equations into the first equation gives us:
T = (A - 2) + 3 + 5
T = A - 2 + 3 + 5
T = A + 1
So the difference between Tom and Alfie is T - A = A + 1 - A = 1 kg.

Fill in the table using this function rule y = 5+5x
Answers
Using the function rule y = 5 + 5x, we can fill in the table as follows:
x | y
0 | 5
1 | 10
2 | 15
3 | 20
4 | 25
To fill in the table using the function rule y = 5 + 5x, we can substitute different values of x into the equation and calculate the corresponding values of y.
Let's create a table:
x | y
0 | 5 + 5(0) = 5 + 0 = 5
1 | 5 + 5(1) = 5 + 5 = 10
2 | 5 + 5(2) = 5 + 10 = 15
3 | 5 + 5(3) = 5 + 15 = 20
4 | 5 + 5(4) = 5 + 20 = 25
Using the function rule y = 5 + 5x, we can substitute each value of x into the equation to find the corresponding value of y. For example, when x = 0, y = 5. When x = 1, y = 10, and so on.
Therefore, the completed table is:
x | y
0 | 5
1 | 10
2 | 15
3 | 20
4 | 25
These values satisfy the given function rule y = 5 + 5x.

3. Which of the following is an example of overdraft protection?
A. Bank pays you interest on money in your savings account
B. Bank collects additional fees when you bounce a check
OC. ATM machine provides you with cash
D. Bank charges a large fee for bouncing a check
PLEASE HELP 4 $
Answers
Answer:
D. Bank charges a large fee for bouncing a check is not an example of overdraft protection.
Step-by-step explanation:
Overdraft protection is a service offered by banks that allows you to link your checking account to another account, such as a savings account or a line of credit. If you overdraw your checking account, the bank will automatically transfer funds from the linked account to cover the shortfall, which helps you avoid overdraft fees and other penalties.
Option A is not an example of overdraft protection as it refers to earning interest on money in your savings account, which is a separate service.
Option B refers to additional fees collected by the bank when you bounce a check, which is a penalty for not having sufficient funds in your account to cover the check.
Option C refers to an ATM machine providing you with cash, which is a basic function of an ATM and is not related to overdraft protection.

Answers
The value of x from the given equation is -1
Given the equation expressed as:
\(3(x - 10) - 5x = 2x - 26\)
Expand using the distributive law as shown:
3x - 3(10) - 5x = 2x - 26
3x - 30 - 5x = 2x - 26
Collect the like terms to have:
3x - 5x - 2x = -26 + 30
-2x - 2x = -26 + 30
Simplify the result by addition and subtraction:
-4x = 4
Divide both sides by -4 (Division property of equality)
-4x/-4 = 4/-4
x = -1
Hence the value of x from the given equation is -1

For a line with a slope a and a known point (h, k), the point-slope form is:
y = a*(x - h) + k
How to write an equation in point slope form?A general linear equation can be written in slope-intercept form as:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that a line passes through a point (h, k), then the point-slope form of that line is:
y = a*(x - h) + k
Notice that particularly, the y-intercept can be written as (0, b), then the slope-intercept form is also a point-slope:
y = a*(x - 0) + b

The 95% confidence interval would be given by (49.66;54.54)
Step-by-step explanation:
Information given
\(\bar X= 52.1\) represent the sample mean
\(\mu\) population mean (variable of interest)
s=12.3 represent the sample standard deviation
n=100 represent the sample size
Confidence interval
The confidence interval for the mean is given by the following formula:
\(\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}\) (1)
The degrees of freedom are given by:
\(df=n-1=100-1=99\)
The Confidence is 0.95 or 95%, and the significance would be \(\alpha=0.05\) and \(\alpha/2 =0.025\), the critical value for this case is: \(t_{\alpha/2}=1.984\)
Replacing the info given we got:

Answers
The value of the expression f(a) is f(a) = a^2 + 7a, based on the given function f(x) = x^2 + 7x and the value x = a
How to form the expression for f(a)?The given parameters in the question are:
f(x) = x^2 + 7x and
x = a as in f(a)
This means that the equation of the function f(x) is given as:
f(x) = x^2 + 7x
To calculate the value of the function f(a), we simply substitute a for x in the equation of the function f(x) = x^2 + 7x.
This means that we set x to a in the equation of the function f(x) = x^2 + 7x.
So, we have;
f(a) = a^2 + 7a
The above equation cannot be further simplified or expanded
So, we conclude that
Based on the given function f(x) = x^2 + 7x and the value x = a, the value of the expression f(a) is f(a) = a^2 + 7a

Answers
The factor that produces the corresponding dimensions of cylinder B is: 3/2.
What are Similar Solids?Similar solids have the same shape but different sizes, and which means the ratio of their corresponding linear measurements are the same.
How to Find the Scale Factor of Similar Solids?To find the scale factor of similar solids, you can use the formula:
scale factor = (size of the similar solid) / (size of the original solid)
For example, if you have two similar solids, one with a volume of 64 cubic units and the other with a volume of 16 cubic units, the scale factor would be:
scale factor = (16 cubic units) / (64 cubic units) = 1/4
This means that the smaller solid is 1/4 the size of the larger solid.
Given the following:
Circumference of the base of cylinder A = 4π units [the radius = 2 units]
Area of the base of cylinder B = 9π units² [the radius = 3 units]
Scale factor = radius of the base of cylinder B / radius of the base of cylinder A
Scale factor = 3/2

What are parallel lines?Parallel lines are lines that have the same slope but pass throuh different points.
The diagram consists of parallel lines that have a common transversal, therefore;
The alternate interior angles are congruentThe same side interior angles are supplementaryThe alternate exterior angles are congruentThe corresponding angles are congruentVertical angles are congruent (vertical angle theorem)1. The 87° angle and the Angle 1 are alternate interior angles, therefore;
87° ≅ Angle 1
87° = Angle 1
The 87° angle and the Angle 2 are same side interior angles
Therefore;
87° + Angle 2 = 180°
Angle 2 = 180° - 80° = 100°
Angle 2 = 100°
2. The 78° angle and the Angle 1 are corresponding angles, therefore;
78° ≅ Angle 1
Angle 1 = 78° (by the definition of congruency)
Angle 1 and Angle 2 are vertical angles
Therefore, Angle 1 is congruent to Angle 2 by vertical angle theorem
