The 14.2 cm correct 1 decimal place is 14.2 after rounding to the nearest 0.1 or the tenth place.
What is rounding off the number?Rounding is a technique to reduce a large number to a smaller, more approachable figure which is very similar to the actual. Rounding numbers can be achieved in a variety of ways.
It is given that:
14.2 cm correct 1 decimal place
14.2
Rounded to the nearest 0.1 or
the Tenths Place.
Rounded to the nearest tenth place. The 2 in the tenth place rounds down to 2 or stays the same because the digit to the right in the hundredth place is 14.2
Thus, the 14.2 cm correct 1 decimal place is 14.2 after rounding to the nearest 0.1 or the tenth place.

Ethan and Adrian are reading the same book. At the beginning of the month, Ethan was on page 18 and Adrian was on page 45. Ethan will read 12 pages per day and Adrian will read 9 pages per day. Let E represent the page of the book that Ethan is on at the end of t days into the month, and let A represent the page of the book that Adrian is on at the end of t days into the month. Write an equation for each situation, in terms of t, and determine whether Ethan or Adrian is farther along in the book after 4 days.
The equations are e = 18+12t and a = 45+9t
Adrian will be father along in the book after 4 days. She will be 15 pages ahead of Ethan
Ethan's page number at the beginning of the month = 18
Adrian's page number at the beginning of the month = 45
Pages read by Ethan each day = 12 pages
Pages read by Adrian each day = 9 pages
Let e represent the page of the book that Ethan is on at the end of t days into the month. Let a represent the page of the book that Adrian is on at the end of t days into the month.
Formulating the equation we get the following:
e = 18 + 12t
a = 45 + 9t
Finding the page number of both Ethan and Adrian after 4 days by substituting the values in the equations we get:
e = 18+12(4)
e = 66
a = 45 + 9(4)
a = 81

Show that 155 can be expressed as the sum of a power of 2 and a cube number.
128 = 2^7 is a power of 2
27 = 3^3 is a perfect cube
=======================================================
Explanation:
This is something you'd find through trial and error.
The powers of 2 are
2, 4, 8, 16, 32, 64, 128, 256, ...
We double each value to get the next one.
The largest power of 2 that is smaller than 155 is 128
155-128 = 27 which is a cube number since x^3 = 3^3 = 27 as you've shown in the screenshot.
If the result of 155-128 wasn't a perfect cube number, then you'd have to try the next largest power of 2 (which is 64) and work your way down the list.
----------------------
Or you could work with the list of perfect cubes
1, 8, 27, 64, 125, 216, ...
Each value is of the form x^3 where x is a whole number.
Let's pick the largest perfect cube that is under 155, and subtract it
155-125 = 30 which isn't a power of 2 (refer to the list above)
Then try 155-64 = 91 which isn't a power of 2 either
Keep moving down the list until reaching 155-27 = 128 which is a power of 2 since 2^7 = 128

Write an equation in point-slope form of the line that passes through the given point and with the given slope m. A. (1, -8) m= -9
The point-slope form of a line is:
y = mx + b
where m is the slope and b is the y-intercept
Replacing with point (1, -8) and m= -9, we get:
-8 = (-9)(1) + b
-8 = -9 + b
-8 + 9 = b
1 = b
Then, the equation is:

Find the value of c that makes t^2 - 22t+ c a perfect square trinomial.
Write the expression as the square of a binomial.
The expression is
The expression is a perfect square trinomial if and only if c = 121.
How to get the value of c?
A perfect square trinomial is written as:
(a + b)^2 = a^2 + b^2 + 2ab
In this case, we have:
t^2 - 22t + c
We can rewrite this as:
t^2 - 2*11*t + c
Then we have:
a = t
b = -11
And we will have that:
c = b^2 = (-11)^2 = 121
Then we have:
t^2 - 2*11*t + 121
Which is a perfect square trinomial:
(t - 11)^2 = t^2 - 22t + 121

a newsletter publisher believes that less than 68h% of their readers own a rolls royce. for marketing purposes, a potential advertiser wants to confirm this claim. after performing a test at the 0.050.05 level of significance, the advertiser failed to reject the null hypothesis. what is the conclusion regarding the publisher's claim?
A potential advertiser for marketing purpose, after performing a test at 0.05 level of significance fails to reject the null hypothesis leads to the conclusion that there is not sufficient evidence at the 0.05 level of significance to say that the percentage is less than 68%.
Hypothesis testing refers to a statistical inference approach used to determine if the available data sufficiently support a particular hypothesis. Hypothesis testing enable researchers to make probabilistic statements about population parameters. In the given case, the null and alternative hypothesis regarding the publisher’s claim state:
The null hypothesis stated that the 68% or more of the readers own a Rolls Royce. H0: p ≥ 0.68
The alternate hypothesis states that less than 68% of the readers own a Rolls Royce. H1: p < 0.68
As the advertiser failed to reject the null hypothesis, it was accepted and thus, 68% or more of the readers own a Rolls Royce. It is concluded that there is not sufficient evidence at the 0.05 level of significance to say that the percentage is less than 68%.

Write an expression for the perimeter in terms of x. 2x and x+3
The perimeter of rectangle with the given dimensions is 6x+6.
Given that the dimensions of rectangle are 2x and x+3.
We need to find the perimeter of the given rectangle.
What is the perimeter of a rectangle?The overall length of the outline determines a shape's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Rectangle perimeter is calculated using the formula perimeter of a rectangle = 2(l + w), where l is the rectangle's length and w is its width.
We know that, the perimeter of rectangle = 2(Length + Width)
Now, perimeter
=2(2x+x+3)
=2(3x+3) (Add like terms)
Using distributive property multiply 2 to 3x and 2 to 3
We get 6x+6
Therefore, the perimeter of rectangle with the given dimensions is 6x+6.

Dean is on in his car and was going 10 m/s but sped up to 100 m/s in 5 seconds. Find his acceleration
Answer:
18 m/s²
Step-by-step explanation:
You want Dean's acceleration when his speed changes from 10 m/s to 100 m/s in 5 seconds.
AccelerationAcceleration is the rate of change of velocity, the change in velocity divided by the corresponding change in time:
a = ∆v/∆t
a = (100 m/s -10 m/s)/(5 s) = (90 m/s)/(5 s) = 18 m/s²
Dean's acceleration is 18 m/s².

Additional comment
Both velocity and acceleration are vector quantities. They have both magnitude and direction.
We assume the given speeds are in the same direction, so the direction of the velocity vector does not change. The acceleration is in that same direction.

Question 9 of 12
AMORTIZATION Car loans are often spread into multiple regular payments over time. This process is called amortization. Each payment
reduces the remaining principal, and the interest accrued for the next payment is based on the reduced principal. The monthly payment is
fixed; so, with each subsequent payment, an increasing portion goes toward principal, and a decreasing portion goes toward interest. Lori
takes out a car loan of $15,000 for 3 years, with a 3% interest rate. When the loan is amortized into monthly payments, the total interest paid by
the end of the loan term will be $704.
Calculate the simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years.
$15
The simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years is $ 1,350.
It is given in the question that:-
Principal = $15,000
Time period = 3 years
Interest rate = 3 %
Total interest paid by Lori, if the loan was amortized = $ 704.
We have to find the simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years.
We know that,
Simple interest = (Principal*Rate*Time)/100
Hence,
Simple interest = (15000*3*3)/100 = $ 1350.

You need a 30% alcohol solution. On hand, you have a 75 mL of a 10% alcohol mixture. You also have 55% alcohol mixture. How much of the 55% mixture will you need to add to obtain the desired solution?
60 ml of the 55% solution is required to get the desired solution.
A unique kind of homogenous mixture made up of two or more substances is called a solution.
A solute is a substance that has been dissolved in a solvent, which is the other substance in the mixture. Polarity effects of chemicals are engaged in the mixing of a solution at a scale that leads to interactions that are very specific to solvation. When the solvent makes up a significant large portion of the combination, as is frequently the case, the solution typically or normally has the condition of the solvent. The concentration of a solution, which measures how much solute is present in a given volume of solution or solvent, is one crucial parameter.Let x ml of 55% solution is taken.
therefore alcohol = 0.55x ml
water = 0.45x ml
Now it is added to 10% 75 ml solution.
Alcohol = 10% of 75 = 7.5ml
Water = 67.5 ml
New mixture = 75 + x
Alcohol = 30% of (75+x) = 22.5 + 0.3x
Therefore 22.5 + 0.3x = 7.5 + 0.55x
or, x = 60 ml
Therefore 60 ml of the 55% solution is required.
