What Lewis did wrong was that; He budgeted more than the maximum recommended amount of money for transportation.
How to budget effectively?
We are given;
Net spendable income = $2,000 per month
Now, we see how much he has budgeted for other items such as Car payments, Gas/Oil, Insurance, License/Registration, Taxes, Maintenance/Repair.
Now, from the recommended transportation budget of between 15% - 20% of the net spendable income, we can see that he would likely spend more than that if we add the cost of maintenance and repair.
Thus, what Lewis did wrong was that he budgeted more than the maximum recommended amount of money for transportation.

When 7/11 is written as a decimal, what is the sum of the first 20 digits after the decimal point? Pls Help
There's a neat trick to finding the rational form of a repeating decimal number. Take for instance [tex]x=0.123123123\ldots[/tex]. Then
[tex]x = 0.123123123\ldots \\\\ \implies 1000x = 123.123123\ldots \\\\ \implies 1000x - x = 123.123123\ldots - 0.123123\ldots \\\\ \implies 999x = 123 \\\\ \implies x = \dfrac{123}{999}[/tex]
It's easy to reverse this method to find the repeating decimal form of [tex]\frac7{11}[/tex]. Let
[tex]x = \dfrac7{11}[/tex]
Multiply the numerator and denominator by 9,
[tex]x = \dfrac{63}{99}[/tex]
It follows that
[tex]x = \dfrac{63}{99} \\\\ \implies 99x = 63 \\\\ 100x - x = 63.6363\ldots - 0.6363\ldots \\\\ \implies x = 0.636363\ldots[/tex]
The first 20 digits after the decimal are made up of 10 each of 3 and 6, so the sum is 10 × (3 + 6) = 90.

The polynomial within the numerator is 9x²+45x+54.
Given the denominator of the initial expression is [tex]\frac{?}{3x^2+15x+18}[/tex] and also the rational expression simplifies to three.
A mathematical expression which will be rewritten to a rational fraction, an algebraic fraction specified both the numerator and therefore the denominator are polynomials. and a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.
Let's take the polynomial within the numerator is k.
So, rewrite the given expression as
[tex]\frac{k}{3x^2+15x+18}=3[/tex]
or it also can be written as
[tex]\frac{k}{3x^2+15x+18}=\frac{3}{1}[/tex]
Cross multiply either side as a×d=b×c where a=k, b=3x²+15x+18, c=3 and d=1 and acquire
k=3(3x²+15x+18)
Simplify the above expression,
k=9x²+45x+54
Hence, the polynomial within the numerator within the given expression [tex]\frac{?}{3x^2+15x+18}[/tex] which is simplified to 3 is 9x²+45x+54.

The height in feet, h, of a model rocket t seconds after launch is given by the equation h (t) = 3 + 70 t minus 16 t squared. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?
The rocket is traveling six times as fast when t = 3 than it is when t = 1.
The rocket is at a greater height when t = 3 than it is when t = 1.
The rocket is 6 feet higher above the ground when t = 3 than it is when t = 1.
The rocket is traveling at a constant rate of 6 feet per second between t = 1 and t = 3.
The average rate of change in h(t) is 6.
What is Average Rate of change?It is a measure of how much the function changed per unit, on average, over that interval.
h(t) = 3 + 70t - 16t²
Average rate of change
At t = 1 second
h(1) = 3 + 70(1) - 16(1)^2
h(1) = 57
At t = 3 second
h(3) = 3 + 70(3) - 16(3)^2
h(3) = 69
Average rate of change = Δh / Δt
=[h(3) - h(1)] / (3 - 1)
= (69 - 57) / 2
= 12 / 2
= 6.
Hence, the rate of change is 6.

What is inverse of a function?Suppose that the given function is
f: X → Y
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
f⁻¹: Y → X
It simply means, inverse of 'f' is an undo operator, that takes back the effect of 'f'
The function is given below.
f(x) = (1/4)x – 12

Tom was able to save 35% more this year than he did last year. If he saved $140 last year, how much did he save this year?
Answer:
$189
Step-by-step explanation:
35% of 140 = 49
140 + 149 = 189
Tom's total saving this year is $189.
It is a 35 percent increased saving from last year's $140.
What are percentages?Percentages are fractional values where the denominator is fixed to be 100.
To convert percentage into number, we multiply by 100.
How to solve the question?In the question, we are informed that Tom was able to save 35% more this year than he did last year.
We are asked if he saved $140 last year, then how much did he save this year.
The increase in Tom's savings = 35% of last year's savings,
or, the increase = 35/100 * 140 (To convert percentage into quantity, we divide by 100).
or, the increase = $49.
Therefore, Tom's total savings this year = Last year's savings + Increase,
or, Tom's total saving this year = $140 + $49 = $189.

Okay, so out of 8 kids, we know that 6/8 are girls and 2/8 are boys. Its asking us what fraction of the kids are girls. The denominator (the bottom part of the fraction will be the amount of kids at the party, 8) and the top part, the numerator, will be 6 as there are 6 girls at the party of the 8 attendees.
So the fraction is 6/8. However we can reduce this by dividing both sides of the fraction by a common factor, 2!
