Under his cell phone plan, Samuel pays a flat cost of $41.50 per month and $5 per gigabyte. He wants to keep his bill at $52.50 per month. Write and solve an equation which can be used to determine
x
x, the number of gigabytes of data Samuel can use while staying within his budget
Answer:
2.2 gigabytes
Step-by-step explanation:
Let us represent
x = the number of gigabytes of data Samuel can use while staying within his budget
Therefore, our equation is:
$41.50 + $5 × x = $52.50
41.50 + 5x = 52.50
Subtract 41.50 from both sides
41.50 - 41.50 + 5x = 52.50 - 41.50
5x = 11
x = 11/5
x = 2.2 gigabytes.
The number of gigabytes of data he need to keep his monthly cost at $52.50 is 2.2 gigabytes

Identify the following series as arithmetic, geometric, both, or neither
[tex]2x + 2 {x}^{2} + 2 {x}^{3} + ... + 2 {x}^{n} [/tex]
Given:
The series is
[tex]2x+2x^2+2x^3+...+2x^n[/tex]
To find:
Whether the given series is arithmetic, geometric, both, or neither.
Solution:
We have,
[tex]2x+2x^2+2x^3+...+2x^n[/tex]
Difference between consecutive terms are:
[tex]d_1=a_2-a_1[/tex]
[tex]d_1=2x^2-2x[/tex]
[tex]d_1=2x(x-1)[/tex]
And,
[tex]d_2=a_3-a_2[/tex]
[tex]d_2=2x^3-2x^2[/tex]
[tex]d_2=2x^2(x-1)[/tex]
Here, [tex]d_1\neq d_2[/tex].
So, the given series is not an arithmetic series.
Ratio between consecutive terms are:
[tex]r_1=\dfrac{a_2}{a_1}[/tex]
[tex]r_1=\dfrac{2x^2}{2x}[/tex]
[tex]r_1=x[/tex]
And,
[tex]r_2=\dfrac{a_3}{a_2}[/tex]
[tex]r_2=\dfrac{2x^3}{2x^2}[/tex]
[tex]r_2=x[/tex]
Similarly upto last pair of consecutive terms.
[tex]r_{n-1}=\dfrac{a_n}{a_{n-1}}[/tex]
[tex]r_{n-1}=\dfrac{2x^n}{2x^{n-1}}[/tex]
[tex]r_{n-1}=x[/tex]
Since, [tex]r_1=r_2=...=r_{n-1}[/tex], so the given series have a common ratio.
Therefore, it is a geometric series.

Question 18. Suppose we have a piece of cardboard that is 40 cm by 25 cm.
Answer:
a. The length of the box = (40 - 2·x) cm
The height of the box = x cm
The width of the box = (25 - 2·x) cm
b. The formula for the volume of the box as a function of x is 4·x³ - 130·x² + 1000·x
c. The value of x that would maximize the volume of the box is x = 5 cm
d. The largest volume of the box is 2250 cm³
Step-by-step explanation:
a. The given parameters are;
The length of the cardboard = 40 cm
The width of the cardboard = 25 cm
The length of the box = (40 - 2·x) cm
The height of the box = x cm
The width of the box = (25 - 2·x) cm
b. The formula for the volume of the box = The area of the base of the box × Height of the box
The area of the base of the box = (40 - 2·x) × (25 - 2·x) = 1000 - 80·x - 50·x + 4·x²
∴ The area of the base of the box = 4·x² - 130·x + 1000
The height of the box = x
The volume of the box = (4·x² - 130·x + 1000) × x = 4·x³ - 130·x² + 1000·x
The volume of the box in terms of x, V = 4·x³ - 130·x² + 1000·x
c. At the extremum point, dV/dx = 12·x² - 260·x + 1000 = 0
x = (260 ± √((-260)² - 4 × 12 × 1000))/(2 × 12)
x = (260 ± 140)/(24)
x = 5 or x = 16.[tex]\bar 6[/tex]
At x = 5, the volume of the box is V = 4×5³ - 130×5² + 1000×5 = 2250
The volume of the box is V = 2250 cm³
At x = 16.67, the volume is 4×16.67³ - 130×16.67² + 1000×16.67 = -925.[tex]\overline {925}[/tex]cm³
Therefore, the value of x that would maximize the volume of the box is x = 5 cm
d. The largest volume of the box is 4×(5 cm)³ - 130×(5 cm)² + 1000×(5 cm) = 2250 cm³.
Santa needs to hire extra help for the busy season. 9 elves can pack 27 toys in Santa's sleigh in an hour.
How many elves are needed to pack 240 toys each hour?
Answer:
Number of elves= 80 elves
Step-by-step explanation:
If 9 elves can pack 27 toys per hour. This means that each elf packs 3 toys per hour:
Toys per elf= 27/9 = 3
Now, we need to determine the number fo elves needed to pack 240 toys per hour:
Number of elves= number of toys/toys per elf
Number of elves= 240/3
Number of elves= 80 elves
Work out the percentage change to 2 decimal places when a price of £198 is increased to £209.99.
Answer:
The percentage change = 6.05%
Step-by-step explanation:
New value = £209.99
Old value = £198
Percentage change = [New Value - Old Value] / [Old Value] × 100
= [209.99 - 198] / [198] × 100
= [11.99] / [ 198] × 100
= 0.06 × 100
= 6.05%
Therefore, the percentage change = 6.05%

Consider a 176lb male farmer is in 104 degree heat. On this day, the humidity is low enough such that all the sweat evaporates from the farmer's skin, enabling him to maintain a body temperature of 100 degrees. The farmer sweats 1 liter of water per hour and 60% of the latent heat needed to Evan=pirate this sweat is provided by farmer's body. If the farmer suddenly dehydrates and stops sweating, how long will it take for his body temperature to rise to the near-fatal 104 degrees.
Answer:
t = 33 seconds
It is the amount of time when the temperature of the body will rise from 100 to fatal 104 in the absence of sweat.
Step-by-step explanation:
weight of the farmer = 176 lb
Sweating = 1 litre per hour
60% of above sweating is evaporated by the latent heat from farmers body.
Temperature outside = 104
Temperature of the Farmer = 100
Time to rise the temperature 4 degrees = ?
We need to use the specific heat formula to calculate the time to rise the temperature of the body of farmer.
Before, that let's convert weight of the farmer in Kg
W = 176 lb
1 lb = 0.453592 kg
176 lb = 79.8 kg
w = mg
g = 10
mass = m = 79.8/10
mass = 7.98 kg
Q = mc∆T
c = specific heat of water = 4,186
∆T = Temperature Change = 104-100
∆T = 4
Q = 7.98 x 4186 x 4
Q = 133617
t = Q/P
Power of Sun's Heat = 3.846×1026
t = 33 seconds
It is the amount of time when the temperature of the body will rise from 100 to fatal 104 in the absence of sweat.

Write the equation for a parabola with a focus at (-7,-5) and a directrix at x = -4
Answer:
y² + 10y + 6x + 58 = 0
Step-by-step explanation:
Focus of the parabola has been given as (-7, -5) and directrix as x = -4
Let a point on the parabola is (x, y).
By the definition of a parabola, "distance of a point on parabola is equidistant from focus and directrix".
Distance from focus of the given point = [tex]\sqrt{(x+7)^2+(y+5)^2}[/tex]
Distance of the point from directrix = [tex]\sqrt{(x+4)^2}[/tex]
Therefore, equation of the parabola will be,
[tex]\sqrt{(x+7)^2+(y+5)^2}=\sqrt{(x+4)^2}[/tex]
[tex](x+7)^2+(y+5)^2=(x+4)^2[/tex]
x² + 14x + 49 + y² + 10y + 25 = x² + 8x + 16
y² + 14x + 10y + 74 = 8x + 16
y² + 10y + 6x + 58 = 0

The taxi ride was 14 miles long.
Step-by-step explanation:
So we know that he payed 29 $. Out of this 29$ 1$ was the pick up fee. So we know that 28$ were spend on distance that the taxi had to ride. We also know that Wyatt has to pay 2$ for each mile so in order to get the total number of miles the car drove we will have to divide the amount of money that was paid for the actually distance traveled by two. And so we get that our answer is........
28$ / 2$ = 14
Which describes the correlation shown in the scatterplot?
Answer:
Option.B
There is a negative correlation in the data set
The correlation shown in the data is negative correlation.
What is Scatterplots?Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
Positive correlation is defined as the relationship where the value of y increases with the increase in the value of x.
Negative correlation is defined as the relationship where the value of y decreases with the decrease in the value of x.
Here the points are in such a way that the value of y decreases with increase in x.
So it is negative correlation.
Hence the correct answer is negative correlation.

Given that;
Oliver read for 450 minutes this month.
And, His goal is to read for 10% more minutes next month.
Now,
Since, His goal is to read for 10% more minutes next month.
Hence, The extra minutes for next month = 10% of 450 minutes
= 10/100 × 450
= 45 minutes
Thus, The total minutes to read in all during the two months is,
⇒ 450 + (450 + 45) minutes

the area of a triangle is 84 CM2. find the altitude corresponding to the side measuring 14 cm?
Answer:
12 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the altitude )
Here A = 84 and b = 14 , then
[tex]\frac{1}{2}[/tex] × 14 × h = 84
7h = 84 ( divide both sides by 7 )
h = 12
The altitude is 12 cm
