Answers

Answer:

37.68 feet.

Step-by-step explanation:

Circumference = diameter *  π

= 12 * π

=  37.68 feet.

The answer is 37.68
Distance around is circumference which is pi times diameter so 3.14 times 9 = 37.68

Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting Low, Medium, High, Very high
Age month, months, months, months, months
Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?

Answers

Answer:

there are so many ways

Step-by-step explanation:

such as observing day by day and checking its height with a scale everyday etc

The number of ways of combining different growth factors to form a level is 80.

What is Permutation?

The act of organizing all the components of a set into some sequence or order is known as permutation. Permuting, in other words, is the act of reordering the components of a set that has previously been sorted.

A permutation is the selection of r items from a collection of n items without replacement, with the order of the items being significant.

nPr = (n!) / (n-r)!

What is a Combination?

The combination is a method of picking elements from a collection in which the order of selection is irrelevant (unlike permutations).

A combination is a selection of r items from a collection of n items with no replacements and no regard for order.

nCr = (n!)/{(r!)((n-r)!)}

How do we solve the given question?

We are given that Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.

Growth factor Levels

Lighting: Low, Medium, High, Very high.

Age: 1 month, 2 months, 3 months, 4 months, 5 months.

Temperature: 20°, 22°, 24°, 26°.

We are asked to find the number of ways in which she can combine different levels to form one level.

We first check the number of combinations for each factor and then multiply them all to get the total number of ways possible.

Lighting: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 = 4).

Age: 5 (∵ All the 5 levels are possible, so the combinations are 5P1 = 5).

Temperature: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 =4).

∴ Total number of ways of combining different growth factors to form a level = 4*5*4 = 80

∴ The number of ways of combining different growth factors to form a level is 80.

A triangle has one side that is 4 centimeters long and one that is 9 centimeters long. The third side is a whole number of centimeters. What is the longest possible third side?

Answers

Answer:

  12 cm

Step-by-step explanation:

You want the longest possible integer length of the third side of a triangle with sides 4 cm and 9 cm.

Triangle inequality

The triangle inequality requires the longest side be less than the sum of the other two sides:

  x < 9 cm + 4 cm

  x < 13 cm

The largest integer length less than 13 cm is 12 cm.

The longest possible third side is 12 cm.

Which of the following rates is the best deal on a box of cereal?

options:

$3.20 for 20 ounces


$4.50 for 25 ounces


$5 for 40 ounces


$6.50 for 20 ounces

Answers

Answer:

C. $5 for 40 ounces

Step-by-step explanation:

First, we need to find the unit rate for each deal.

To do this, we divide the price of the cereal box by the unit (ounces):

1. $3.20 for 20 ounces

3.20/20 = $0.16 for each ounce

2. $4.50 for 25 ounces

4.50/25 = 0.18 for each ounce

3. $5 for 40 ounces

5/40 = 0.13 for each ounce

4. $6.50 for 20 ounces

6.50/20 = 0.33 for each ounce

As you can see, the third one is the best deal, as it is the least expensive.

Answer:

$43 million

Step-by-step explanation:

Step 1. Turn the sentence into an equation (total = T)

15.4 million = 0.36 (T)

Step 2. Solve for T

15,400,000 / 0.36 = T

42,777,777.78 = T

$42.8 million ≈ $43 million (rounded)

The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!

Hope this helps :)

If line m || line n and Ð2 measures 35°, what is the measure of Ð5?

Answers

Answer:

145

Step-by-step explanation:

angle 2 = angle 3

=>          angle 3 = 35

now, we have

=>         35+angle 5 = 180

=>         angle 5 = 180 - 35

=>         angle 5  = 145

Answer:

145°

Step-by-step explanation:

line m || line (Given)

[tex]m\angle 2 = 35\degree ......(1)[/tex] (Given)

[tex]m\angle 3 = m\angle 2 ......(2)[/tex] (vertical angles)

From equations (1) and (2)

[tex]\implies m\angle 3 = 35\degree[/tex]

[tex]m\angle 3 +m\angle 5 = 180\degree[/tex] (interior angles on the same side of transversal)

[tex] \implies 35\degree +m\angle 5 = 180\degree[/tex]

[tex] \implies m\angle 5 = 180\degree-35\degree[/tex]

[tex] \implies m\angle 5 = 145\degree[/tex]
