Step-by-step explanation:
I assume it means the task is filled completely.
diameter = 2.1 m
therefore, radius = diameter/2 = 2.1/2 = 1.05 m
height = 4 m
volume of a cylinder is
ground area × height, so
pi×r² × height = pi×1.05²×4 = 13.8544236... m³
1 cm³ is 1g
for 1 kg (remember, "k" stands for "kilo" and means 1000) we need therefore 1000 cm³ (which is a cube of 10 cm side length).
how many cm³ are in 13.8544236... m³ ?
1 m = 100 cm
1 m² = 1 m × 1 m = 100×100 = 10,000 cm²
1 m³ = 1 m × 1 m × 1 m = 100×100×100 = 1,000,000 cm³
that means a factor of 1,000,000 !
so, the volume of the cylinder is
13.8544236... × 1,000,000 = 13,854,423.6... cm³
to get the mass of kg of that much water we need now to divide by 1000 :
13,854,423.6... / 1000 = 13,854.4236... kg
which is, by the way, 13.8544236... tons.
yes, 1 m³ of water is 1 ton ...
I don't know, if you need to round the result.
if you e.g. only need full kg, then the answer would be
13,854 kg.
add 4 to 7, then multiply 5 by the result??

[tex] { \dashrightarrow \sf \qquad2x= - 100} \\ \\ [/tex]
Dividing 2 from both sides :

Answer:
Step-by-step explanation:
The number of shoes a cobbler (shoemaker) can make varies directly with the amount of time the cobbler spends making the shoes.
If the cobbler can make 3 pairs of shoes in two hours, how would you write this equation?
Group of answer choices
y=3x
y=4x
y=2x
y=1. 5x
The pairs of shoes increases as the time the cobbler works increases
The equation of the pairs of shoes is y = kx
How to determine the equation?The variation is a direct variation.
So, we have:
y = kx
Where:
y represents the number of shoesx represents the time in hoursk represents the proportionality constantThe cobbler can make 3 pairs of shoes in two hours,
So, we have:
k = 3/2
k = 1.5
Substitute k = 1.5 in y = kx
y = 1.5x
Hence, the equation of the scenario is y = kx

A fireman leans a ladder against a building. The base of the ladder is 5 feet from the building. The ladder is 13 feet long. How far up the side of the building is the top of the ladder?
12 ft
Using 13 for c, and 5 for a, you can use Pythagorean’s theorem a^2+b^2=c^2 to find b, the height
5^2+b^2=13^2
25+b^2=169
b^2=144
b = 12
Complete the table of successive approximation to find the x-value of the solution of f(x)=g(x) to the nearest hundredth f(x)= x^2-2 g(x) = x-1
The solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62
How to find the solution to a given set of function?Given the following function below:
f(x) = x^2 - 2
g(x) = x - 1
Since f(x) = g(x), hence;
x^2 - 2 = x - 1
x^2 - x - 1 = 0
Factorize to have:
x = 1/2 +√5/2 or x= 1/2 - √5/2
x = 1.62 or -0.62
Hence the solution of f(x)=g(x) to the nearest hundredth if f(x)= x^2-2 g(x) = x-1 is 1.62 or -0.62

The mean of a set of data is 12367. The mean of absolute deviation is 350. Select the numbers below that are within the mean absolute deviation. A. 12,116 B.12,001, C. 12,990, D. 12,705, E. 12720.
The numbers given below that fall within the mean absolute deviation of the data are: C. 12,990, D. 12,705, E. 12720.
What is the Mean Absolute Deviation?The mean absolute deviation is simply the average of the distance of each of the data points there are in a data distribution.
The difference of each data point from the mean is most likely within the same range with the mean absolute vallue.
If we subtract 12,990, 12,705, and 12720 from the mean of the data, 12,367, we would get a figure close to the mean absolute deviation, 350.
So the numbers that are within the mean absolute deviation are, C. 12,990, D. 12,705, E. 12720.

A vender bought an earphone for $1378 and she sold it in order to make a profit of 17. 5% calculate the profit made in cash and the selling price
The profit he made from selling his hearing aids at a profit of 17% is $234.26.
How to calculate the profit obtained?To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.
$1,378 ÷ 100 = $13.78$13.78 × 17 = $234.26Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.

Which ordered pair is a solution to the system of linear equations? 2x 3y= 6 –3x 5y = 10 (0,2) (2,0) (3,2) (2,3)
An equation is formed of two equal expressions. The ordered pair which is the solution of the system of linear equations is (0,2).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation can be done in the following manner.
2x+3y=6
3x+5y=10
Let's take the first equation and find write it in terms of y. therefore, the first equation can be written as,
[tex]2x+3y=6\\\\2x=6-3y\\\\x = \dfrac{6-3y}{2}[/tex]
Now, substitute the value of x in the second equation,
[tex]3x+5y=10\\\\3(\dfrac{6-3y}{2})+5y=10\\\\18-9y +10y = 20\\\\-9y+10y=20-18\\\\y=2[/tex]
Thus, the value of y is 2. substituting the value of y in the first equation to get the value of x.

Linda rented 8 movies and 4 video games for a total of $37. The next month she rented 3 movies and 2 video games for a total of $17. Find the rental cost for each movie and each video game.
Answer:
Let x = the price of movies and let y = the price of video games
8x + 3y = 43
2x + 5y = 32
Use the Elimination Method by multiplying both sides of the second equation by 4
8x + 3y = 43
-(8x + 20y = 128)
-17y = -85
y = 5
2x + 5(5) = 32
2x + 25 = 32
2x = 7
x = 7/2 = 3.5
Movies cost $3.50 and video games cost $5
