There are between 24 and 40 students in a
class.
The ratio of boys to girls is 4:7
How many students are in the class?

Answers

Answer:

Step-by-step explanation:

The ratio of boys is 4/11

You need a number that is divisible by 11.

11 represents the number of students in the class. That was obtained by adding 4 and 7 together. So there are 4/11 boys and 7/11 girls.

You could try 33 which is between 24 and 40

4/11 * 33 = 12

There are twelve boys in the class.

7/11 * 33 = 21

There are 21 girls in the class.

21 + 12 = 33 which is exactly what you need.

Answer:

f = 13[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given that f and e are congruent then e = f

Using Pythagoras' identity in the right triangle

f² + e² = 26² , that is

f² + f² = 676

2f² = 676 ( divide both sides by 2 )

f² = 338 ( take the square root of both sides )

f = [tex]\sqrt{338}[/tex] = [tex]\sqrt{169(2)}[/tex] = 13[tex]\sqrt{2}[/tex] ≈ 18.4 ( to 1 dec. place )

Answer:

f = 25.85751233

Step-by-step explanation:

f^2+E^2=26^2

A jeweler had a fixed amount of gold to make bracelets and necklaces. The
amount of gold in each bracelet is 6 grams and the amount of gold in each
necklace is 16 grams. The jeweler used 178 grams of gold and made 7 more
necklaces than bracelets. Write a system of equations that could be used to
determine the number of bracelets made and the number of necklaces made.
Define the variables that you use to write the system.

Answers

Find the solution set of the inequality \qquad52- 3x < -14.52−3x<−14.52, minus, 3, x, is less than, minus, 14, point \qquad xxx

Answers

Answer:

x > 22

Step-by-step explanation:

Given the inequality;

52- 3x < -14

Subtract 52 from both sides

52 - 3x - 52 < -14 - 52

-3x < -14 - 52

-3x < -66

Divide both sides by -3

-3x/-3 < -66/-3

x > 22

Hence the required inequality is x > 22

PLEASE HELPPPPPP FINDING CIRCUMFERENCE AND AREA OF A CIRCLE

Answers

Answer:

The circumference of the circle is 28.26 m.

The area of the circle is 63.585 [tex]m^{2}[/tex].

Step-by-step explanation:

To solve for the circumference of the circle, start by using the circumference formula of a circle, which is [tex]C= 2\pi r[/tex]. However, 3.14 will be used instead of [tex](\pi)[/tex] for this formula.

First, the radius of the circle needs to be found. To find the radius of the circle, divide the diameter by 2 because the radius equals half of the diameter. The radius is 9 m divided by 2, which equals 4.5 m.

Next, plug in the radius into the formula, and the formula will look like [tex]C=(2)(\pi )(4.5 m)[/tex]. Then, solve the equation, and the answer will be 28.26 m.

To solve for the area of the circle, start by using the area formula of a circle, which is [tex]A=\pi r^{2}[/tex]. However, 3.14 will be used instead of [tex](\pi)[/tex] for this formula.

For the area, plug the radius into the formula, and the formula will look like [tex]A= (3.14)(4.5m)^{2}[/tex]. Then, solve the equation, and the answer will be 63.585 [tex]m^{2}[/tex].

Tanya has 130 ml of juice

Answers

Answer:

The answer is below

Step-by-step explanation:

A drink is made by adding water to juice.

Instructions

Add an amount of water that is between 3 times and 5 times the amount of juice

Tanya has 130 ml of juice.

If she follows the instructions, work out the minimum and maximum amounts

of the drink she can make.

Solution:

The minimum amount of water that can be added to the juice is 3 times the amount of the juice, hence:

Minimum amount of water = 3 * 130 ml of juice = 390 ml of water

Therefore minimum amount of drink = 390 ml of water + 130 ml of juice

minimum amount of drink = 520 ml

The maximum amount of water that can be added to the juice is 5 times the amount of the juice, hence:

Maximum amount of water = 5 * 130 ml of juice = 650 ml of water

Therefore maximum amount of drink = 650 ml of water + 130 ml of juice

Maximum amount of drink = 780 ml

Rural farms disappear. American farmers lose their lands to banks and businesses. Food prices around the world are rising steadily. What can people do to get fresh vegetables when the nearest countryside is miles away? The answer is to plant urban gardens. Urban gardening is a new trend in megacities like New York, Chicago, and other big cities around the globe. Many of these cities have started programs to help gardeners. People are welcome to grow herbs and vegetables on balconies and roofs, vacant lots, abandoned yards, and even on the shoulders of highways. With a little thought, any city dweller can think of an area of land on which to grow a garden. Gardeners must be careful because, in a city, chemicals can contaminate the land. To help with this, cities are beginning to test the soil for free. It is important that more cities around the world turn to green programs to make cities more eco-friendly. As citizens begin to grow more and more gardens around the globe, environments will become more stable and less hazardous. Gardens will return more oxygen into the air and will lower greenhouse gases in our atmosphere. Urban gardening groups have begun to petition city governments to begin more green programs to assist the gardening movement. Think about how many rooftops are in a city. Skyscrapers have large, flat roofs. Urban gardeners use these roofs to construct large planters for vegetables, grass, trees, and shrubs. All of these roofs are built to allow water to run off their surfaces. This means that irrigation for crops is not a problem. These rooftop gardens make cities greener and more fertile. They also help the environment by refreshing the air and by reducing smog and effects to the ozone layer. One element that the urban gardening movement needs more than anything else is loyal members. As an interested reader, look into joining a local gardening group or inquire at your city office about starting a group on your own.
