Answers
The value of the variable 'w' for the given equation 7 ( w + 7 )³ = 7(6³) is equal to w = -1.
As given in the question,
Given equation is equal to :
7 ( w + 7 )³ = 7(6³)
Divide both the side of the equation by 7 we get,
⇒ 7 ( w + 7 )³ / 7 = 7(6³) /7
⇒( w + 7 )³ = (6³)
Take cube root both the side of the equation we get,
⇒∛( w + 7 )³ = ∛(6³)
⇒ w + 7 = 6
Now subtract 7 from both the side of the equation we get,
⇒w + 7 - 7 = 6 - 7
⇒ w = -1
Therefore, the value of the variable 'w' for the given equation is equal to w = -1.

A square plot of land has side lengths of 40 meters. An archeologist divides the land into 64 equal parts What is the area of
each part?
Answers
Find the area of the plot of land:
40 x 40 = 1600 square meters.
Now divide total area by parts:
1600 / 64 = 25 square meters.
Answer: 25 square meters
Step-by-step explanation:
Area of each part = Area of plot/Total parts
Area = 40 × 40/64
Area = 10 × 40/16
Area = 10 × 10/4
Area = 100/4
Area = 25 m²
The length of a rectangle is 6 inches more than the width. The perimeter is 28 inches. Find the length and the width (in inches).
Answers
Answer:
The length of the rectangle is 10 inches, and the width is 4 inches.
Step-by-step explanation:
Given that the length of a rectangle is 6 inches more than the width, and the perimeter is 28 inches, the following calculation must be performed to find the length and the width:
(X + X + 6) x 2 = 28
2X + 2X + 12 = 28
4X = 28 - 12
X = 16/4
X = 4
Therefore, the length of the rectangle is 10 inches, and the width is 4 inches.
The variable s varies directly as the square of t. When s = 4, t = 12. Nick’s work finding the value of t when s = 48 is shown:
What is the first error, if any, in Nick’s work?
See in pic:
Answers
Answer:
C - He substituted incorrectly when calculating the constant of variation.
The first error, in Nick’s work is given inn option C, i.e. He substituted incorrectly when calculating the constant of variation.
What is constant of variation?Constant of variation is the ratio between two variables in a direct variation or the product of two variables in an inverse variation.
We have,
s = 4, and t = 12
Now according to the question,
The variable s varies directly as the square of t,
i.e.
s = kt²
So,
Substituting given values of s and t,
s = kt²
i.e.
4 = k × 12²
⇒
\(k = \frac{4}{144}=\frac{1}{36}\),
Now,
for 48,
i.e.
s = kt²,
We get,
\(48 = \frac{1}{36} t^2\),
i.e.
\(t^2=36 *48=1728\)
\(t=\sqrt{1728} = \sqrt{3*576} =24\sqrt{3}\)
So, this is the correct value for t.
Hence, we can say that the first error, in Nick’s work is given inn option C, i.e. He substituted incorrectly when calculating the constant of variation.

Answers
The one making the most money in one week is by sales manager which is an amount of $1006.25.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
Given that,
Hourly rate of a head mechanic = $37.52 per hour
Number of hours worked in a week = 25 hours
Money made = 25 × 37.52 = $938
Hourly rate of a assistant mechanic = $30.42 per hour
Number of hours worked in a week = 30 hours
Money made = 30 × 30.42 = $912.6
Hourly rate of a sales manager = $28.75 per hour
Number of hours worked in a week = 35 hours
Money made = 35 × 28.75 = $1006.25
Hourly rate of a front desk clerk = $15.09 per hour

My equation looked like this but I got this question wrong so any help will be appreciated
9667=11211e^(.418)(t)
Answers
The number of years it would take is approximately equal to 53 years.
How to determine the population after a number of year?In Mathematics, a population that increases at a specific period of time represent an exponential growth. This ultimately implies that, a mathematical model for any population that increases by r percent per unit of time is an exponential function of this form:
P(t) = I(1 + r)^t
Where:
P(t ) represent the population.t represent the time or number of years.I represent the initial number of persons.r represent the exponential growth rate.By substituting given parameters, we have the following:
96627 = 11211(1 + 0.0418)^t
8.61894567835 = (1.0418)^t
By taking the ln of both sides, we have:
Time, t = ln(8.61894567835)/ln(1.0418)
Time, t = 52.60 ≈ 53 years.

Answers
According to the given table the line of best fit is
f(x)=4.54x+77.84
The term "line of best fit" describes a line that passes across a scatter plot of data points and best captures their connection. Statisticians often utilise regression analysis software or manual computations to arrive at the geometric equation for the line using the least squares approach. A straightforward linear regression study of two or more independent variables will provide a straight line.
Hence, as asked by the question we need to find the time at which the tempurature will become 100°C.
To find that let us put f(x)=100 and find out the value of x for which it is satisfied.
4.54x+77.84=100
⇒\(x=\frac{100-77.84}{4.54}=4.88\)
⇒x≈5
Therefore the time at which the tempurature is 100°C is 5 minutes.

A shipping box is 36 inches by 24 inches by 18 inches
how many cubic feet can it hold
Answers
Answer:
To find the volume of the shipping box in cubic feet, we need to convert the dimensions from inches to feet and then calculate the volume.
Given:
Length = 36 inches
Width = 24 inches
Height = 18 inches
Converting the dimensions to feet:
Length = 36 inches / 12 inches/foot = 3 feet
Width = 24 inches / 12 inches/foot = 2 feet
Height = 18 inches / 12 inches/foot = 1.5 feet
Now, we can calculate the volume of the box by multiplying the length, width, and height:
Volume = Length * Width * Height
Volume = 3 feet * 2 feet * 1.5 feet
Volume = 9 cubic feet
Therefore, the shipping box can hold 9 cubic feet.
Step-by-step explanation:
First convert the units because it's asking for the cubic feet but they give us the measurements in inches.
To convert inches to feet we divide the number by 12.
36 ÷ 12 = 3
24 ÷ 12 = 2
18 ÷ 12 = 1.5
Now to find the volume, we multiply it all together.
3 × 2 × 1.5 = 9
It can hold 9 cubic feet.

Jacob and Dustin collected 245 cast for the school can job they give 55 cast to Dustin's little sister to take to her class how many cans does this leave for the boys class
Answers
Answer:
190 cans
Step-by-step explanation:
Total cans collected by Jacob and Dustin for the school can job = 245
Amount of cans they both gave to Dustin's little sister = 55
Now because they gave out cast out of the total they initially had, there would be a deduction in the amount both boys would now have.
To determine the amount the boys are left with, we would deduct 55 casts from the amount they had which 245.
Amount of cans left = 245-55 = 190
Amount of cans left for the boys class = 190 cans

Given the equations a × b = 5742 × 6368, a × c = 5748 × 6362, and c × b = 5738 × 6372, we need to determine the relationship between the three variables a, b, and c.
By comparing the given equations, we notice that the numbers on the right-hand side of each equation are very close to each other, differing only by small amounts. This suggests that a, b, and c are approximately equal.Since a × b, a × c, and c × b involve the same numbers with slight variations, we can conclude that a, b, and c are all very close in value.
Therefore, the inequality we can infer from this information is a ≈ b ≈ c, indicating that a, b, and c are approximately equal.
