Alf earns £9.00 per hour and works 33 hours each week. He spends a total of £24.40 each week travelling to and from work. Next month he is getting a 4% pay rise but his travel costs are increasing by 15%.
How much extra will he have each week?
Answers
Answer:

$72 is 4.5% of what amount
Answers
$72 is 4.5% of 6.25 amount. 6.25 Percentage of 72 is 4.5.
By considering the given information
[tex]72\times x=4.5\\x=\frac{4.5}{72}\times 100\\ x=6.25[/tex]
A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. percent, which is a relative value used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

The elevation of a small submarine changes by-mile after each exploration. After
how many explorations will the submarine's elevation have changed by -1 miles?
Answers
The submarine's elevation would have changed by -3/2 mile after 4 explorations.
What is elevation?An elevation is a view of a three-dimensional shape from the side or the front. "Rise over run" is an easy-to-remember equation for calculating a change in elevation as a decimal, which means the rise (the change in vertical distance) divided by the run (the change in horizontal distance).So, to find how many explorations will the submarine's elevation has changed by -1 miles:
After each exploration, the submarine's elevation changes by -3/8 mile.To calculate the number of explorations required to change the submarine's elevation by -3/2 mile, divide -3/2 mile by the number of miles the submarine's elevation changes per exploration (that is, -3/8 mile).Then,
-3/2 miles ÷ -3/8 mile-3/2 ÷ -3/8 mile-3/2 × -3/8 mile24/64Therefore, the submarine's elevation would have changed by -3/2 mile after 4 explorations.

What is Uncertainty?
The range of potential values between which the genuine value of both the measurement can be found is referred to as uncertainty in this context.a) A basket's capacity for eggs:
The measurement that is precise and free from uncertainty is the number of counting objects. Consequently, we are able to precisely count the eggs in a basket.
b) The weight of 12 bananas:
Given that no two bananas are the same size and therefore have different masses, it is uncertain to determine the mass of a dozen bananas. This is true for the computation of the mass of any object.
c) The iron block's mass
Because no two pieces of iron in an iron block are the same size, it is difficult to determine the mass of an iron block.
d) The quantity of gasoline required to fully fill a car's gas tank:

Answer:1.75
Step-by-step explanation:
7x+8=3x+15
4x+8=15
4x=7
x=1.75
Step by step
Angle 1 and angle 3 are vertical angles, they are congruent /the same/ equal.
Angle 1 = 7x + 8
Angle 3 = 3x + 15
So our equation is
7x + 8 = 3x + 15
Solve for x
Subtract 3x from both sides to combine variables
7x - 3x + 8 = 3x - 3x + 15
4x + 8 = 15
Now subtract 8 from both sides to isolate x
4x + 8 - 8 = 15 - 8
4x = 7
Divide both sides by 4 to solve for x
4/4 x = 7/4
x = 1.75
Now to answer the question
What is the value of angle 1?
Angle 1 is 7x + 8
Substitute 1.75 for x in the equation
(7)(1.75) + 8 = angle 1
20.25 = angle 1
Check your work and do the same for Angle 3
3x + 15
Substitute 1.75 for x
(3)(1.75) + 15 = angle 3
20.25 for angle 3

Contra positive: If five isn't an excellent number, then 3 isn't a main number. (False)
Converse: If 5 is a good number, then 3 may be a prime quantity. (True).

describe and illustrate the situation when the minimum of a two variable function can be placed higher than its maximum. what type of extrema is this?
Answers
For the rare case that the outcome of the second derivative matrix examination is inconclusive, higher order derivatives have to be examined.
What do math extrema mean?
Any point in calculus when the value of a function is either the highest (a maximum) or the lowest (a minimum) (a minimum). There are maxima and minima that are both absolute and relative (or local).Identify every stationary point. The solution set that results from setting the partial first derivatives to zero includes those points.Look at each stationary point's personality. This is done explicitly in the first case by looking at the eigenvalues of the second derivative matrix. The fact that there are quick formulas for this if there are just two variables, is superior.Higher order derivatives must be investigated in the improbable event that the results of the second derivative matrix study are ambiguous. Sadly, no set recipes can be developed in this situation; rather, each function must be considered individually.Learn more about extrema mean

Answers
Answer:

Step-by-step explanation:
Given transversal x crossing lines y and z and angles numbered 1 to 8, you want the number of the angle that is an alternate interior angle to angle 4.
Alternate interior anglesIn this context, "alternate" mean the angles are on opposite sides of the transversal. "Interior" means the angles are between the lines the transversal crosses.
The term "alternate interior angles" is used to refer to angles that have their vertices at the intersection points where the two lines cross the transversal. (It excludes angles that have the same vertex, or do not share a side.)
The angle that is an alternate interior angle relative to angle 4 is angle 5.
