.........???????
Part A
Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.
Part B
What is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.
Part C
The pyramid of Khufu, also known as the Great Pyramid of Giza, is one of the Seven Wonders of the World. Its volume is about 2,433,400 cubic meters, and its height is about 138 meters. Substitute these values into the equation from Part B, and solve the equation.
Part D
Search the Internet to find the length of each side of the base of Khufu’s pyramid. Does this length match your calculation?
Part E
Khafre was a son of Khufu. He also had a pyramid built, but it was not as big as his father’s. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?
Part F
Search the Internet to find the length of each side of the base of Khafre’s pyramid. Does this match your calculation?
Part G
About how much longer are the side lengths of the base of Khufu’s pyramid than Khafre’s?
Answer:
Part A: S^2= 3V/H
Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]
Part C: s=√3* 2,433,400 /138=230 metres
Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.
Part E: S = √3*2,115,072/ 136 =216 metres
Part F: The length of Khafre's pyramid is about 215.5 My calculation was a little off, but not by much.
Part G: 14 meters longer
Step-by-step explanation:
Part A:
I am going to solve:
So,
V=1/3 [tex]HS^{2}[/tex]
Then, multiply both sides by 3:
V x 3= 1/3 [tex]HS^{2}[/tex] x 3
So,
3V=[tex]HS^{2}[/tex]
Then, we divide by H:
[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]
So,
[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]
Then switch sides:
[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]
I hope this helps!

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students
Solve the inequality. a−2>4
Answer:
a>6
Step-by-step explanation:
Find the 14th term of the geometric sequence 2, 6, 18,
The geometric sequence is starting with 2 and multiplying by 3 every time. We can get the rule of this sequence by...
If 2 is a_0, 6 is a_1, 18 is a_2, etc.
a_n=2*3^n
For the 14th term, which is a_13, the value is 2*3^13.
Using a calculator because I'm too lazy to calculate 3^13 sorry, we can get.
3188646
The required 14th term will be 3188646 in the given geometric sequence.
What is geometric series?The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
The geometric sequence is given in the question, as follows:
2, 6, 18,...
We have to determine the 14th term of the given geometric sequence.
As per the given geometric sequence,
The first term a = 2.
The common ratio r = 6/2 = 3
14th term = arⁿ⁻¹
Substitute the value of a = 10, r = -2, and n = 12 in the formula,
14th term = 2(3)¹⁴⁻¹
14th term = 2(3)¹³
14th term = 2(1594323)
14th term = 3188646
Thus, the required 14th term will be 3188646.

Hey i really need help with this question im having trouble and it would be greatly appreciated if someone could help me
Answer:
m=s+0.50
3m+2s=23.95
Step-by-step explanation:
Answer:
m-s+0.50
3m+2s=23.95
Step-by-step explanation:
the first one is defining m in terms of S
the second is solving
I know they didn't ask but here is the solution:
so in this case you would replace 3m with 3(s+0.50)
16. A fifteen passenger van is rented for a family vacation. The van rental is $75.00 per day, plus a $160.00 insurance fee. Which equation could be used to find x, the number of days the car be rented if they want to spend exactly $760.00 on the van rental?
A. 75.00 + 160.00x = 760 00
B. 75.00x - 160.00 = 760.00
C. 75.00 - 160.00x = 760.00

Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel
help pls asap ty ! ! !
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.

The chart below displays information regarding the number of picture frames sold by a store in a given month.
According to the chart, what fraction of the frames sold during the four-month period were sold in march? Hint: Determine the total number of frames sold and then write a fraction with March/total and simplify.
a. 3/10
b. 1/4
c. 1/5
d. 1/6
e. 1/10
Answer:
1/4
Step-by-step explanation:
Calculate the frames of each month:
January = 350
February = 100
March = 250
April = 300
Solve
[tex]\frac{March}{Total} = \frac{250}{350 + 100 + 250 + 300} = \frac{250}{1000}[/tex]
Simplify
[tex]\frac{250}{1000} = \frac{25}{100}= \frac{1}{4}[/tex]

What is the slope intercept ?
Please help me !!
Answer:
y=mx+b
Step-by-step explanation:
Answer:
slope=3, y-intercept=1
Step-by-step explanation:
slope is rise/run, so if you rise 3 and run 1 on the line, you get 4 for the slope, the y intercept is where the line crosses the y-axis, in this situation, it crosses it at (0,1).
