Answer:

f=6 and s=18

Step-by-step explanation:

Let's solve your system by substitution.

s+f=24;s=3f

Rewrite equations:

s=3f;f+s=24

Step: Solves=3ffor s:

s=3f

Step: Substitute3fforsinf+s=24:

f+s=24

f+3f=24

4f=24(Simplify both sides of the equation)

4f

4

=

24

4

(Divide both sides by 4)

f=6

Step: Substitute6forfins=3f:

s=3f

s=(3)(6)

s=18(Simplify both sides of the equation)

Answer:

f=6 and s=18

In Normal distribution(z) tomato plants have height less than 4.07 feet is 97.93 %.

Normal distribution is a "continuous probability distribution that its symmetrical around its mean with most values near the central peak".

According to the question,

The heights of tomato plants are Normally distributed.

Mean(μ) = 3.56

Standard deviation (σ)  = 0.25

For a tomato plants that has a height of 4.07 feet

In order to find Percentage of tomato plants have a height less than 4.07 feet

Standard Normal Distribution Formula,

z = (x-μ)/σ    where X~(μ,σ).

  = [tex]\frac{4.07-3.56}{0.25}[/tex]

  = [tex]\frac{0.51}{0.25}[/tex] = 2.04.

P ( x < 4.05) = P( z < 2.04 )

                     = 0.9793           ( Using standard Normal distribution table)

To find the percentage of tomato plants have height less than 4.07 feet is

multiply 0.9793 by 100

                     = 97.93%

Hence, Using Standard Normal distribution we find tomato plants have height less than 4.07 feet is 97.93 %

Answer: 5/9 yards

Step-by-step explanation:

From the question, we are informed that Jack made 9 identical bags using 5 yards of fabric.

To calculate the amount of fabric that Jack use for each bag, we have to divide 5 by 9. Thus will be:

= 5 / 9

Therefore, it means that Jack used 5/9 yards for each bag

Answer:

#1: 146 degrees #2: 111 degrees

Step-by-step explanation:

The angles of a heptagon (a shape with 7 sides) are supposed to add up to 900 degrees, so just add up all the sides that you know and subtract it from 900 and you will have x! Do the same thing with the second one, except is is a hexagon and all the angles should add up to 720 degrees. (Don't forget to add the right angle, which is 90 degrees) So add up all the sides you know and subtract from 720 to get x.

P.S. If correct, please give Brainliest?

Answer:

N = number of sides

The sum of the interior angles of a polygon is equal to (N x 180)-360.

The first problem has 7 sides so the interior angle total = 900 degrees.

Add up all the known interior angles:

96+105+161+123+155+114+x = 900

x = 900-754 = 146 degrees

The second problem has 6 sides so the interior angle total = 720 degrees.

Add up all the known interior angles:

127+40+202+90+150+x = 720

x = 720-609 = 111 degrees

Answer:

0.3643

Step-by-step explanation:

Standard Form and Scientific Notation

What is standard form of numbers?

Standard form is the normal way of writing numbers no matter how big or small the number is.

Examples:

15,000,000

0.0000000678

What is scientific notation?

Scientific notation is a different way of expressing numbers. It is a short way of expressing very big numbers or very small numbers. It is also known as exponential form. Scientific notation is written as the product of a number and a power of 10.

Examples:

1.3 × 10⁶

34.5 × 10^⁻9

Going back to the question above, we need to convert the given scientific notation to its standard form.

Converting of Scientific Notation to Standard Form

To convert a number from scientific notation to standard form, move the decimal point.

The exponent tells the direction and the number of times we need to move the decimal point.

The positive exponent indicates a large number so we need to move the decimal point to the right.

The negative exponent indicates a small number so we need to move the decimal point to the left.

Do not write the power of 10 anymore.

Solution:

Now, let us convert 3.643 x 10^-1 in standard form.

The exponent is negative 1 so we will move the decimal point to the left once.

3.643 = 0.3643

Answer:

1224 cm^3

Step-by-step explanation:

volume = bottom area x height

102x12=1224

The fish tank holds 1224 cc of water.

In mathematics, volume is the space taken by an object.

Here, given that,

The area of the bottom of the tank =A= 102 cm²

now, the height of the water in tank = h= 12cm

we know, volume of water= A× h  

                                           =102×12 cc

                                           =1224 cc

Hence, required volume is 1224 cc

Given:

A figure of a right angle triangle.

To find:

The length of the shorter leg.

Solution:

In a right angle triangle,

[tex]\tan\theta =\dfrac{Opposite}{Adjacent}[/tex]

In the given triangle,

[tex]\tan (60^\circ) =\dfrac{18}{x}[/tex]

[tex]\sqrt{3}=\dfrac{18}{x}[/tex]

[tex]x=\dfrac{18}{\sqrt{3}}[/tex]

[tex]x=\dfrac{18}{\sqrt{3}}\times \dfrac{\sqrt{3}}{\sqrt{3}}[/tex]

On further simplification, we get

[tex]x=\dfrac{18\sqrt{3}}{3}[/tex]

[tex]x=6\sqrt{3}[/tex]

[tex]x=10.3923[/tex]

[tex]x\approx 10.4[/tex]

Therefore, the length of the shortest leg is 10.4 and the correct option is B.

Notes:

The rabbit population in Central Park in 2005 is 192 rabbits.

To find the rabbit population in Central Park in 2005, we need to calculate the growth from 1995 to 2005.

From 1995 to 2005, there is a total of 10 years.

Using the growth rate of 8.5% per year, we can calculate the population in 2005:

Population in 2005 = 85 rabbits(1 + 0.085)¹⁰

Calculating this expression:

Population in 2005 = 85 rabbits(1.085)¹⁰

= 85 rabbits × 2.2609

= 192 rabbits

Therefore, the estimated rabbit population in Central Park in 2005 is 192 rabbits.
