The ratio of the volume of the cylindrical tank to its surface area will be r / 2.
What is a cylinder?A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Let r be the radius and h be the height of the cylinder.
Then the volume of the cylinder will be
V = π r²h cubic units
Then the surface area of the cylinder will be
SA = 2πrh square units
Then the ratio of the volume of the cylindrical tank to its surface area will be
V / SA = π r²h / 2πrh
V / SA = r / 2
The ratio of the volume of the cylindrical tank to its surface area will be r / 2.

If a lawnmower has a cost price of $2500 and was sold for $2895 what is the percentage profit
The profit percentage for the lawn owner is 15.8%
Profit Percentage:
Profit means, if the selling price of a product is more than its cost price, there is a profit earned in the transaction.
So, it can be calculated as,
Profit = Selling Price - Cost Price
The formulas for profit percentage is,
Profit percentage(P%) = (Profit /Cost Price) × 100
Given,
Here we need to find the profit percentage, If a lawnmower has a cost price of $2500 and was sold for $2895.
Based on the question,
We know that,
Cost Price = $2500
Selling Price = $2895
So, the profit is,
profit = $2895 - $2500
profit = $395
Now, the profit percentage is calculated by apply the values on the formula,
profit percentage (P%) = (395/2500) x 100
Therefore,
P% = 395/25
P% = 15.8%
Therefore, the profit percentage for the lawn owner is 15.8%.

Assuming a 5-point difference between the two sample means, which set of sample characteristics is most likely to produce a significant value for the independent-measures t statistic?
A large mean difference and small sample variances. The correct option is B.
What are sample statistics?A statistical measure known as the effect size () assesses the magnitude of the link (numerically) between two variables. The difference between the weights of male and female candidates, for instance, is known as the effect size. If we obtain information on the weights of male and female candidates and discover that men are, on average, heavier than women, for example.
The weight difference between men and women will increase as the effect size increases. Statistic effect size aids in determining whether a difference is real or the result of changing variables. Effect size, power, sample size, and critical significance level are all related to hypothesis testing.
Therefore, a large mean difference and small sample variances. The correct option is B.

L = 1.3245 is the legnths of the pen's sides .
What is area and perimeter?
Perimeter is the distance around the outside of a shape. Area measures the space inside a shape.
The equation for perimeter is 2L + W = 30 ( I'm assuming that the shed takes up one of the Widths, but you can use the Length if you want, it doesn't matter.)
So W = 30 - 2L.
Area = L x W = L (30 - 2L) = 30L - 2L^2.

the midpoint of FG given F(2, -6) and G(-8, 10) = (-3,2)
Solution :
The midpoint calculator will take two coordinates in the Cartesian coordinate system and find the point directly in-between both of them. This point is often useful in geometry.
1. Label the coordinates(x₁,y₁) and (x₂,y₂).
2. Input the values into the formula.
3. Add the values in the parentheses and divide each result by 2.
4. The new values form the new coordinates of the midpoint.
f we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x,y).

the midpoint of uv is m(10, 6). one endpoint is v(10, 7). find the coordinates of the other endpoint u.
The coordinates of the other endpoint U are found to be (Xu, Yu) = (10, 5).
What is coordinates of a point?The coordinates are a pair of numbers which characterize the exact location of a point on a cartesian plane through using horizontal and vertical lines.
The x and y values of a point on a graph are usually represented by (x, y). Each point or ordered pair has two coordinates.Now, as per the question.
To find the coordinates of U, use the midpoint formula with the coordinates of points u and v (Xv, Yv) and (Xm, Ym) respectively.
Let's refer to them as (Xu, Yu)
Midpoint formula {(Xv + Xu)/2, (Yv + Yu)/2)}
Fill in the recognized coordinates as needed.
Point V at (10, 7) = (Xv, Yv)
Midpoint, point M at (10, 6) = (Xm, Ym)
For the x coordinates;
(10 + Xu)/2 = 10
Xu = 10.
Similarly for the y coordinate;
(7 + Yu)/2 = 6
7 + Yu = 12
Yu = 5
We can test this by plugging U's coordinates into the midpoint formula.
(10 + 10)/2 = 20/2 = 10
(5 + 7)/2 = 12/2 = 6
Therefore, the coordinates of the are (Xu, Yu) = (10, 5).
