Math is a language

say you plant two posts that are 5ft apart and you want to get up to 60ft

right now you've covered 5ft and now have 60 - 5 = 55ft to go.

you plant the next one: 55 - 5 = 50ft to go

instead of subtracting many times and counting hiw many times we've subtracted, we can use division

60ft / 5ft = 12 posts

to verify, you can multiply 5 and 12 which is the same as adding 5 + 5 + 5 + 5 +... + 5 = 5ft x 12 Posts= 60ft in total length

There are 12 posts for 60 feet of straight line fence.

Here,

Given that,

Post are space 5 feet apart.

We have to find number of posts for 60 feet of straight line fence.

What is Division method?

This method of distributing a group of things into equal parts is termed as division.

Now,

We can division method to find number of posts for 60 feet of straight line fence.

Here, Post are space 5 feet apart.

Answer:

Based on the provided information, the table summarizes service times (in seconds) of dinners at a fast food restaurant. To determine the number of individuals included in the summary, we can sum up the frequencies listed in the table:

7 + 24 + 14 + 1 + 4 = 50

Therefore, there are 50 individuals included in the summary.

Regarding the exact values of all the original service times, it is not possible to determine them precisely based on the given information. The table only provides ranges of service times and their corresponding frequencies. We can determine the range within which each individual's service time falls, but we cannot determine the exact value within that range.

Answer:

5:30

Step-by-step explanation:

For 2 ratios to be equivalent they must be proportionate and have the same relationship. In the first ratio, the first number is 1, while in the second it is 5. This means the ratio was multiplied by 5. For the ratios to stay proportionate the second number must also be multiplied by 5. Since 6*5=30 the new ratio is 5:30

These two equations form a system that can be solved to find the values of x and y, representing the number of children and adults, respectively, who played on that day.

The correct system of equations to model this scenario is:

x + y = 414 (Equation 1)

9x + 12y = 3780 (Equation 2)

In this system, x represents the number of children and y represents the number of adults who played that day.

Equation 1 represents the total number of customers, which is 414. It states that the sum of the number of children (x) and the number of adults (y) is equal to 414.

Equation 2 represents the total cost of the games played. Since the cost for a child's game is $9 and the cost for an adult's game is $12, we multiply the number of children (x) by $9 and the number of adults (y) by $12. The equation states that the total cost, which is $3780, is equal to the sum of these individual costs.

Together, these two equations form a system that can be solved to find the values of x and y, representing the number of children and adults, respectively, who played on that day.

What is the ratio and proportion ?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls).

To complete the 1-mile relay race in 4:34, each runner must run their quarter-mile leg of the race in a total time of 1:08 (68 seconds).

Using the normal distribution, it is found that the correct option is:

In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

In this problem:

P(Y < 16) is the p-value of Z when X = 16, hence:

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{16 - 20}{2.3}\)

\(Z = -1.74\)

\(Z = -1.74\) has a p-value of 0.041.

we can conclude that 2/3 is not equal to 4/5.

To determine if 2/3 is equivalent to 4/5, we can compare the fractions by checking if their ratios are equal. The ratio of 2/3 can be written as 2:3, while the ratio of 4/5 can be written as 4:5.

To check if the ratios are equal, we can cross-multiply and see if the products are equal. Cross-multiplying means multiplying the numerator of the first fraction with the denominator of the second fraction, and the numerator of the second fraction with the denominator of the first fraction.

For 2/3 and 4/5, we have:

2 * 5 = 10

3 * 4 = 12

Since 10 is not equal to 12, we can conclude that 2/3 is not equivalent to 4/5.

Answer:

15 cm (shorter side)

50 cm (longer side)

Step-by-step explanation:

Let the length of the shorter side of the parallelogram be x cm. Then, the length of the longer side is (2x + 20) cm. Since a parallelogram has opposite sides equal in length, there will be two shorter sides and two longer sides.

The perimeter of the parallelogram is given as 130 cm. The sum of the lengths of all four sides is equal to the perimeter. Therefore, we can set up the following equation:

2x + 2(2x + 20) = 130

Now, we can solve for x:

2x + 4x + 40 = 130

6x + 40 = 130

6x = 130 - 40

6x = 90

x = 90/6

x = 15

Now that we have found the length of the shorter side (x), we can find the length of the longer side:

Longer side = 2x + 20 = 2(15) + 20 = 30 + 20 = 50

So, the dimensions of the parallelogram are 15 cm (shorter side) and 50 cm (longer side).

The dimensions of the parallelogram are 15 cm x 50 cm.

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure.

Given that, in a parallelogram, the longer side is 20 cm longer than twice the shorter side. the perimeter is 130 cm.

We need to find the dimension of the parallelogram,

Let the length of the shorter side of the parallelogram be x cm.

Then, the length of the longer side is (2x + 20) cm.

The perimeter of the parallelogram is given as 130 cm.

Therefore, we can set up the following equation:

2x + 2(2x + 20) = 130

Now, we can solve for x:

2x + 4x + 40 = 130

6x + 40 = 130

6x = 130 - 40

6x = 90

x = 90/6

x = 15

Longer side = 2x + 20 = 2(15) + 20 = 30 + 20 = 50

Hence, the dimensions of the parallelogram are 15 cm x 50 cm.

Answer:

(f + g)(x) = – 3x^2 + 5x - 8

Step-by-step explanation:

(f + g)(x) = f(x) + g(x)

= 5x^2 + 9x – 4 + (– 8x^2 – 3x – 4)

= 5x^2 + 9x – 4 – 8x^2 – 3x – 4

Combine

= – 3x^2 + 5x - 8

The sum of the given functions is defined as the expression (f + g)(x) which is equal to -3x²  + 6x  – 8.

Use the concept of quadratic function defined as:

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:

ax² + bx + c = 0

The given functions are:

f(x) = 5x² + 9x – 4

g(x) = – 8x² – 3x – 4

Since (f + g)(x) = f(x) + g(x)

Then put the functions,

(f + g)(x) = (5x² + 9x – 4) + ( – 8x² – 3x – 4)

Rearranging like terms,

(f + g)(x) = 5x²– 8x²  + 9x – 3x – 4  – 4

Simplifying it,

(f + g)(x) = -3x²  + 6x  – 8

Hence,

The expression for (f + g)(x) is -3x²  + 6x  – 8.

Step-by-step explanation:

Just find the answer for 40% of the given meters.

Answer:

Probability = 0.10565

Step-by-step explanation:

Given:

Mean, u = 2

x = 2.5

CV = 20% = 0.2

To find standard deviation \( \sigma\) use the formula:

\( CV = \frac{\sigma}{u} \)

\( 0.2 = \frac{\sigma}{2} \)

\( \sigma = 0.2 * 2 \)

\( \sigma = 0.4 \)

Find Z, using the formula:

\( Z = \frac{x - u}{\sigma} \)

\( Z = \frac{2.5 - 2}{0.4} \)

\( Z = \frac{0.5}{0.4} \)

\( Z = 1.25 \)

Using the p value table,

P(x > 1.25) = 0.10565
