The same field can be mowed in 3 hours by 2 gardeners.

A soccer field may be mowed by 6 gardeners in 2 hours, meaning each one works at a rate of 1/6 of the field per hour.

We must ascertain the rate at which the field can be mowed in 3 hours, which is 1/3 of the field every hour, in order to establish the number of gardeners required to mow the same field in that amount of time.

We divide this rate by the rate of each gardener, which is 1/6 of the field each hour, to determine the required number of gardeners, resulting in the equation 1/3 / 1/6 = 2.

Hence, 2 gardeners can mow the same field in 3 hours.

The given information states that the machine produces good pieces with a probability of 0.96, which means that there is a 0.04 probability of getting a bad piece.

To calculate the probability of getting two bad pieces in a row, we multiply the probabilities of each individual bad piece:

0.04 * 0.04 = 0.0016

So the chances of getting two bad pieces are 0.0016, or 0.16%. This means that out of 100 tries, you would expect to get two bad pieces in a row 0.16 times.

It's vital to remember that independent events, like obtaining two terrible pieces, have probabilities that are determined by multiplying the individual possibilities.

This is based on the idea of the multiplication rule of probability, which states that the likelihood of two unrelated events occurring simultaneously is the sum of the probabilities of each event occurring separately.

Step-by-step explanation:

A = bh

You are given the height of 2yd and a base of 4.5 yd.

A = (2yd)(4.5yd)

= 9yd^2

Answer:

9yd

Step-by-step explanation:

3½²-2²= √8.25=2.8

4.5-2.87=1.63

½×2.87×2=2.87

½(4.5+1.63)2=6.13

6.13+2.87=9yd

We divided both sides of the equation by (3/8) to get x = (40/3), the number is 40/3.

Let the number be x.

Then one half of three fourths of x can be expressed as [tex](3/4)*(1/2)*x = (3/8)*x[/tex]

Two fifths of x can be expressed as[tex](2/5)*x[/tex]

Therefore, according to the given statement, [tex](3/8)*x = (2/5)*x - 20[/tex]

Solving for x, we get: x = (40/3)

Therefore, the number is 40/3.

To calculate this, we first wrote the given statement in terms of fractions. Then we used algebraic manipulation to solve for x. We multiplied both sides of the equation by the LCD, 40, to get [tex]40*(3/8)*x = 40*(2/5)*x - 20*40[/tex]. Then we combined like terms to get ([tex]3/8)*x + 20*(5/8)*x = 40[/tex]. Then we subtracted [tex]20*(5/8)*x[/tex] from both sides to get [tex](3/8)*x = 40 - 20*(5/8)*x[/tex]. Finally, we divided both sides of the equation by (3/8) to get x = (40/3).

Step-by-step explanation: use the slope formula.

About $6,000 more compound interest than simple interest is earned after 35 years, and about $12,500 more compound interest than simple interest is earned after 45 years.

What is a graph ?

A graph is a visual representation of data that shows the relationship between two or more variables. It is a way of presenting information in a clear and concise manner that makes it easy to interpret and understand.

Graphs can be used to show trends over time, compare different groups or categories, or illustrate the relationship between two or more variables.

Since the graph shows the balance for two accounts with the same principal and annual interest rate, we can assume that one account is earning simple interest while the other is earning compound interest.

To estimate the amount of compound interest earned after 35 years, we can look at the difference in balance between the two accounts at that time. From the graph, we can see that the balance for the simple interest account after 35 years is approximately $4,000, while the balance for the compound interest account is approximately $10,000. Therefore, the amount of compound interest earned after 35 years is approximately:

$10,000 - $4,000 = $6,000

To estimate the amount of compound interest earned after 45 years, we can again look at the difference in balance between the two accounts at that time. From the graph, we can see that the balance for the simple interest account after 45 years is approximately $5,500, while the balance for the compound interest account is approximately $18,000. Therefore, the amount of compound interest earned after 45 years is approximately:

$18,000 - $5,500 = $12,500

Therefore,  about $6,000 more compound interest than simple interest is earned after 35 years, and about $12,500 more compound interest than simple interest is earned after 45 years.

So the perimeter of the octagon is approximately 45.25 centimeters (rounded to two decimal places).

In geometry, a shape's perimeter is sometimes referred to as its total length. By adding up the lengths of all of an object's sides and borders, one can determine the circumference of something such as a form. The perimeter of a form can be calculated by adding up all of the edges' lengths. For instance, a rectangular with dimensions of 24 yards long as well as 15 yards wide will have a 78 yard perimeter.

Here,

To find the perimeter of the octagon, we need to determine the length of each side of the octagon.

First, let's find the length of the diagonal of the smaller square. We can use the Pythagorean theorem:

d²=4² + 4²=

d² = 16+16 =32

d = √32

=> d = 4√2

​

This diagonal of the smaller square is also the side length of the overlapping square.

Next, let's find the length of one of the sides of the larger square that overlaps with the smaller square. Since the length of the larger square is 6cm, the side length of the overlapping region (part of the larger square that overlaps with the smaller square) is:

6 - 4√2

Finally, the length of one of the sides of the octagon is the sum of the side lengths of the two squares that overlap, minus the side length of the overlapping square (since this side is counted twice):

=> 6 + 6 - 4√2 - 4√2 - (6 - 4√2)

Therefore, the perimeter of the octagon is:

=>8 (12 - 6√2) = 96 - 48√2

So the perimeter of the octagon is approximately 45.25 centimeters (rounded to two decimal places).

The solution of the given problem of triangle comes out to be tan ∠A = 0.25.

Triangles are called polygons if they have four quadrants or more. Its form is a simple geometric figure. When put together, the characters ABC create a right-angled triangle. When the boundaries are incompatible, Euclidean geometry generates a new rectangle with square corners. Triangles are regarded as polygons because they have three edges and three corners.

Here,

Since △ABC is a right triangle with m∠C = 90°, we know that m∠A + m∠B = 90°.

Using the fact that tan ∠B = opposite/adjacent, we can set up a ratio using a common factor, x, for the opposite and adjacent sides of ∠B:

tan ∠B = 0.25 = opposite/adjacent = x/4x

Simplifying the right side, we get:

0.25 = x/4x = 1/4

Multiplying both sides by 4x, we get:

x = 4

So the opposite side of ∠B has length x = 4, and the adjacent side has length 4x = 16.

Using the Pythagorean theorem, we can find the length of the hypotenuse of △ABC:

c² = a² + b²

c² = 4²+ 16²

c² = 256

c = √256

c = 16

Now, we can use the fact that tan ∠A = opposite/adjacent to find tan ∠A:

tan ∠A = opposite/hypotenuse = 4/16 = 1/4

Therefore, tan ∠A = 0.25.

Answer:

To make a frame with an area of 30in², Travis needs to cut out a piece of steel with an area of A = (11+2x)(6+2x)in², where x is the width of the frame. The inside of the frame must be 11in by 6in, so the width of the frame must be x = (30 - 11*6)/4 = 2.25in. The total area of the piece of steel must therefore be A = (11+2*2.25)(6+2*2.25) = 30in².

Step-by-step explanation:

To determine the value of x that will result in a final area of the frame of 30in², we can use the equation for the area of the piece of steel before cutting out the frame:

A = (11 + 2x)(6 + 2x)

We can expand this expression to get:

A = 66 + 44x + 12x^2

Since the inside of the frame has to be 11in by 6in, the area of the frame is 11 * 6 = 66in². So, we want to find the value of x that will result in the area of the piece of steel being equal to the area of the frame plus 30in². This means we want to find the value of x that will satisfy:

66 + 44x + 12x^2 = 96

Expanding the left-hand side of this equation and collecting like terms, we get:

12x^2 + 44x = 30

Dividing both sides of the equation by 12, we get:

x^2 + 3.67x = 2.5

To solve for x, we can use the quadratic formula or factoring. Once we have found the value of x, we can use it to determine the dimensions of the piece of steel before cutting out the frame.

A number which is 15 more than twice a number is 37 is 11.

Let the number be N.

Let's set up the equation.

A number is 15 more than twice a number is 37,

2N + 15 = 37

Let's subtract 15 from both sides.

2N = 22

Divide both sides by 2, and you get

N = 11

So the number which is 15 more than twice a number is 37 is 11.
