Geometric mean of 2 and 10
Answer:2 square root of 5
Step-by-step explanation:
The geometric mean of 2 and 10 is 2√5.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The geometric mean of a and b is √(ab).
Now,
a = 2 and b = 10
so,
The geometric mean of 2 and 10.
= √(2 x 10)
= √20
= 2√5
Thus,
The geometric mean of 2 and 10 is 2√5.

Cual es el volumen del concreto que necesitamos para construir cuatro columnas circulares si el diámetro de cada una es de 50 cms y la altura y la altura son 3,5(la respuesta en ms)
Answer:
27488.92 cm³
Step-by-step explanation:
El volumen de concentre para columna circular = área de superficie del círculo × altura de la columna.
= πr² × h
Dado que:
diámetro = 50 cm
height = d/2 = 50 cm / 2 = 25 cm
= 3.5 cm
Entonces:
El volumen de concentre para columna circular = πr² × h
El volumen de concentre para columna circular = π(25)² × 3.5
El volumen de concentre para columna circular = 6872.23 cm³
Para cuatro columnas circulares; el volumen será: = 4 × 6872.23 cm³
= 27488.92 cm³
Which equation shows the relationship between the volume, (V) of the prism and its height (h)?
Answer:
h = V/lw
Step-by-step explanation:
We know the formula for the volume of a rectangular prism is V = lwh. We need to use this equation and solve for h by dividing lw on both sides.
V = lwh
V/lw = h

Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.
1( Write an equation to represent the number of pages Amir has read.
Use x to represent the number of days Amir has been reading and y to represent the number of pages he has read.
2( Write an equation to represent the number of pages Jesse has read.
Using x, (the number of days Amir has been reading), write an expression to represent the number of days Jesse has been reading. Remember that Jesse started reading one day before Amir. Use this expression to write an equation for the number of pages Jesse has read. Let y represent the number of pages read.
3(Write the system of equations using your answers from questions 1 and 2.
4(You will use substitution to solve this system. Which variable will you substitute for and why? Show the equation that results from the substitution.
5(Solve the system of equations. Show your work.
6(Interpret your solution. How many days does it take Amir to catch Jesse? At that time, how many pages have they read?
Answer: 6 days
210 pages
Step-by-step explanation: As stipulated by the question, let the number of days Amir has been reading be x and the number of pages he had read to be y.
Now since he reads 35 pages per day.
Then mathematically;
y = 35x
For Jesse, He started reading a day before, this means that the number of days he had read would be x + 1. Since he reads 30 per day, the total number of pages he would have read is 30(x+1)
To find the number of days which is x, we have to assume that at a point in time, the number of books they would have read would be the same meaning that
Also; y = 30(x + 1)
Equating the two situations
35x = 30(x + 1)
35x = 30x + 30
35x -30x = 30
5x = 30
x = 30/5
x = 6 days
This means that it will take Amir 6 days to catch Jese.
The number of books they would have read by then is y = 35x = 30(x + 1)
= 35 * 6 or 30(6+1)
= 210
Answer:
1. y = 35x
2. y = 30x + 1
3. 35x = 30x + 1
35x = 30x + 30
35x -30x = 30
5x = 30
x = 6 (30/5 = 6)

The line 1 has equation 5x + 6y + 30 = 0. Given
that P is the point (3, -1), find
(i) the coordinates of the point where l crosses the
x-axis,
(ii) the coordinates of the point of intersection
of l with the line x = 2,
(iii) the equation of the line passing through P
and having the same gradient as I,
(iv) the equation of the line passing through P
and having a gradient of 0.
w through the points ACO 3).
Answer:
Step-by-step explanation:
i) the x-intercept is when y=0
5x+6(0)+30=0
5x=-30
x=-6
hence the point is (-6,0)
ii)5(2)+6y+30=0
10+6y+30=0
6y=-40
y=-20/3
hence the point of intersection is (2,-20/3)
iii) y+1=-5/6(x-3)
6y+6=-5x+15
6y+5x=9
iv) y+1=0(x-3)
y=-1
