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

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 %

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.

Step-by-step explanation:

204 dived by 3.5

i did 204 dived by 60 then

420 dived by 60

The time taken by the family to reach is T = 7 hours

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed be represented as S

Now , the value of S is

S = D / T

speed = distance / time = 204 miles / 3.4 hours = 60 miles per hour

where , the distance D = 420 miles

And , T = 420 / 60

T = 7 hours

Hence , the time taken for 420 miles is 7 hours

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

t = 1200 / ( 6000 × 0.04 ) = 5

t = 5 years

The time required to

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

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.

Step-by-step explanation:

let the ratio be x

now,

3x+5x+9x+13x=360°(sum of angle of quadrilateral is 360°)

30x=360°

x=360/30

x=12°

then,

3x=3×12=36°

5x=5×12=60°

9x=9×12=108°

13x=13×12=156°

so,the angles of quadrilateral are 36°,60°,108°& 156°
