Answer:

1246 yards

Step-by-step explanation:

To find the yard of fencing she needs for he cows, we simply need to find the perimeter of the rectangular area.

The area is 200 yards by 423 yards.

The perimeter is the sum of all the sides of a rectangle and it is given by:

P = 2(L + B)

P = 2(200 + 423) = 2(623)

P = 1246 yards.

She needs 1246 yards of fencing.

Answer:

The energy a 15,000 g block of ice will absorb in order to melt is 4995 kJ

Step-by-step explanation:

The question relates to the latent heat of fusion of ice, that is the heat absorbed by the solid ice to convert it to liquid water without changing its temperature.

The formula for the energy required to melt the ice is presented as follows;

Energy required = Mass, m × Latent heat of fusion, [tex]L_f[/tex], of ice

Hence, the mass, m, of the ice = 15,000 g

Latent heat of fusion, [tex]L_f[/tex], of ice = 333 J/g

Therefore;

Energy required = 15,000 g × 333 J/g = 4995000 J

Hence;

The energy a 15,000 g block of ice will absorb in order to melt = 4995000 J

1000 J = 1 kJ

1 J = 1/1000 kJ

Therefore, 4995000 J = (4995000 J)/(1000 J/kJ) = 4995 kJ.

Which gives;

The energy a 15,000 g block of ice will absorb in order to melt = 4995 kJ.

Answer:

17000 batteries

Step-by-step explanation:

Three years and one month is equivalent to the mean minus one standard deviation.

Three years and seven months is equivalent to the mean plus one standard deviation.

For a normal distribution, we know that 68% of population is between mean ± 1 sd, then can be expected that 25000*68% = 17000 of batteries last between three years and one month and three years and seven months

Answer:D,180

Step-by-step explanation:

Answer:

9 x 20ft = 180

If one of those values 8ft and 20ft is the diagonal then we deduct the square of thise numbers being  √400 -   √81 =  √309 and find  √309 square of  17.57ft

17.57 x 9 = 158.13

so  √158.12 = 12.57

and  √162 = 12.72

But your question was just a case of finding how to do area and for that we use L x W to find area

Answer:  30.5 cm²

To get the the area of the rectangle all we have to do is:

Rectangle Area = 6 × 8 = 48 cm²

Same thing to the circle, multiply the radius and pi:

Circle Area = 3.14 x 5² = 78.5 cm²

We have to subtract the two areas to find the shaded area.

78.5 - 48 = 30.5 cm²

I hope this helps!

Answer: 30.5 cm².

Answer:

No, since the total distance to the cell tower is 16.28 miles, which is farther away than the distance needed to get the best possible service. You are 1.28 miles too far.

Step-by-step explanation:

you have a triangle with sides 12 miles and 11 miles long, so all you need to do is calculate the hypotenuse:

h² = 12² + 11²

h² = 144 + 121

h² = 265

h = √265

h = 16.28 miles

Answer:

A=12x

Step-by-step explanation:

The equation for a rectangle is A=lw

So if you plug in your variables then you would have A=12x

Answer:

they should buy the smaller one. the yogurt will cost money too. that is why other companys put ice, or empty spaces in cups.

Step-by-step explanation:

The soccer club should choose either Container A or Container B, as both options would generate the same profit of $1.00 per container sold, assuming the cost price is $1.50 and the selling price is $2.50.

To determine which container is more profitable, we need to calculate the profit from each option. For both containers, the selling price is $2.50.

Let's assume the cost of each container is $1.50, which includes the frozen yogurt, packaging, and other associated costs.

Container A Profit:

Selling Price: $2.50

Cost Price: $1.50

Profit per Container: $2.50 - $1.50 = $1.00

Container B Profit:

Selling Price: $2.50

Cost Price: $1.50

Profit per Container: $2.50 - $1.50 = $1.00

As we can see, both Container A and Container B would yield the same profit of $1.00 per container, given the assumed cost price and selling price.

Answer:

[tex]P(t)=37\cdot 4^{t/9.1}[/tex]

Step-by-step explanation:

The number of people who receive the email increases by a factor of 4 every 9.1 weeks.

This is an exponential growth of the form:

[tex]A=A_o(r)^{t/k}[/tex]

Where:

[tex]A_o =$Initial value\\r=Growth rate\\k=Growth Period\\t=time[/tex]

In this case:

[tex]A_o =37\\r=4\\k=9.1\:weeks[/tex]

Therefore at any time t, the function describing this scenario is:

[tex]P(t)=37\cdot 4^{t/9.1}[/tex] where t is in weeks.

A linear function adds the same number each time. It has a constant rate of change which means it adds or subtracts a certain amount at each step. An example of this would be the equation y = 3x + 2.

The function described in the question which will add the same number each time is called a linear function. In mathematics, a linear function is a function that has a constant rate of change. This means that it adds or subtracts the same amount each time. For example, the equation y = 3x + 2 is a linear function. Every time you increase x by 1, y will increase by 3. Similarly, each time you decrease x by 1, y will decrease by 3. This is because the slope of a linear function is constant, indicating a consistent rate of change.

To find the equation of the line through (-2, 2) and (5, -5), calculate the slope which is -1 and then use the slope-intercept form to find the y-intercept, which is 0. The equation of the line is y = -x.

To write an equation of the line that passes through the points (-2, 2) and (5, -5), you need to determine the slope and the y-intercept of the line. First, calculate the slope (m) which is the change in y divided by the change in x: m = (y2 - y1) / (x2 - x1).

Using the points (-2, 2) and (5, -5), the slope calculation would be: m = (-5 - 2) / (5 - (-2)) = (-7) / (7) = -1. This indicates that the line has a negative slope.

Next, use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept. To find b, use one of the given points and the slope you calculated: 2 = (-1)(-2) + b, which simplifies to 2 = 2 + b, and thus b = 0.

The equation of the line is therefore y = -1x + 0, which simplifies to y = -x.

Answer:

340

Step-by-step explanation:

Let x = original price

We increase by 25%

x+x*25% = new price

Change to decimal form

x+.25x = new price

Factor out the x

x(1+.25) = new price

x(1.25) = new price

x(1.25) = 425

Divide each side by 1.25

x = 425/1.25

x =340

The original price is 340

Answer:

60%

Step-by-step explanation:

(9/15)*100=60

The percentage of the children take the bus to school will be 60%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

There are 9 children in a class who take the bus to school.

And, There are 15 total children in the class.

Now,

Since, Total children in class = 15

And, There are 9 children in a class who take the bus to school.

So, The percentage of the children take the bus to school will be calculated as;

Percent = (Children to take bus to school / Total children) x 100

            = (9 / 15) x 100

            = 60%

Thus, The percentage of the children take the bus to school will be 60%.
