4. Find the volume of the cylinder. Leave youranswer in terms of π.

Step-by-step explanation:

Ratio in three ways are given below.

The ratio is the number that can be used to represent one quantity as a percentage of another, to put it simply. A ratio's two numbers can only be compared if they share the same unit. Ratios are used to compare two objects. a connection between two values that is typically expressed as the quotient of one value divided by the other. For instance, the ratio of red to blue marbles is 6:4, or six red to four blue marbles, in the case of a box containing six red and four blue marbles. A decimal or percentage can also be used to indicate a ratio.

Given Data

An orchard contains 12 rows of Granny Smith apple trees, 10 rows of Fuji apple trees, 15 rows of Gala apple trees, 2 rows of Golden Delicious apple trees, and 2 rows of Jonathan apple trees.

a) Rows of Gala apple trees to Granny apple smith trees:

Ratio

First way = 15 to 12

Second way = 15:12

Third way = [tex]\frac{15}{12}[/tex]

b) Rows of Fuji apple trees to total number of apple trees

Total number = 12 + 10 + 15 + 2 +2

Total number = 41

Rows of Fuji apple trees = 10

First way = 10 to 41

Second way = 10: 41

Third way = [tex]\frac{10}{41}[/tex]

The measure of largest exterior angles is 150 degrees

Exterior angles are defined as angles of a polygon formed or created by two the sides of that polygon and sharing a common endpoint.

It is important to note that the exterior angle of a triangle is congruent to the sum of the two non-adjacent interior angles that are opposite to each other.

They are also known to be angles formed by a transversal line as it cuts through one of two lines and it is located on the outside part of the line.

Given the angles as;

Note that the sum of exterior angles are 360degrees

5x° + 9x° + 10x° = 360°

collect like terms

24x = 360

Make 'x' the subject of formula by dividing both sides by 24

x = 360/24

x = 15

But the largest angle is 10x = 10(15) = 150°

Hence, the value is 150°

The linear equation of given point (1, -7) and slope -1 is y = -x - 6.

Given:

Point(x₁ , y₁) = (1, -7)

Slope = -1

By using the Point-slope form of the linear equations, we get

y - y₁ = m(x - x₁)

⇒ y - (-7) = -1(x - 1)

⇒ y + 7 = -x + 1

⇒ y = -x + 1 - 7

a. Yes, The situation represents a function.

The independent variable is number of lines and dependent variable is the total cost.

b. The range is 0 ≤ y ≤ 120 and the domain is 0 ≤ x ≤ 4.

What is Domain?

The set of all inputs of the function is called Domain of set.

Given that;

A cell phone plan costs $30 for each line.

Now, Let the number of lines be x and total cost be y.

So, We can evaluate;

y = 30x

Thus, This equation represent Linear function.

So, The situation represents a function.

The independent variable is number of lines and dependent variable is the total cost.

Since, You can have a maximum of four lines on a plan.

So, The possible values are;

x = 0, 1, 2, 3, 4

After substitute all the value of x in equation y = 30x we get;

For x = 0

y = 30 × 0 = 0

For x = 1

y = 30 × 1 = 30

For x = 2

y = 30 × 2 = 60

For x = 3

y = 30 × 3 = 90

For x = 4

y = 30 × 4 = 120

Thus, The range of the function will be 0 ≤ x ≤ 4.

And, The domain of the function will be 0 ≤ y ≤ 120.

Therefore,

a. Yes, The situation represents a function.

The independent variable is number of lines and dependent variable is the total cost.

b. The range is 0 ≤ y ≤ 120 and the domain is 0 ≤ x ≤ 4.

The length of the rectangle is 30 feet and the width of the rectangle is 15 feet.

Let l be the length l the rectangle and w be the width of the rectangle.

The area of a rectangular living room is 450 square feet.

⇒ A = l × w

⇒ 450 = l × w                     ................(1)

The length of the room is 15 feet less than three times the width.

So we get an expression,

l = 3w - 15

Substitute above vale of l in equation (1)

450 = (3w - 15) × w        

450 = 3w² - 15w

3w² - 15w - 450 = 0

w² - 5w - 150 = 0

(w - 15)(w + 10) = 0  

w - 15 = 0  or w + 10 = 0

w = 15    or    w = -10

But width of the rectangle cannot be -10

So, w = 15 feet

and l = 3(15) - 15

l = 30 feet

If there are three blue marbles, five red marbles, and four green marbles, the probability of selecting a red marble is

Remember that the probability is the ratio between the number of events and the total number of all the events. In this case, the number of events is 5 because there are 5 red marbles, and the total number of all events is the sum of all the marbles.

Therefore, the probability of selecting red marbles is 5/12.

Notice that we have three different ratios, that is because each time we select a red marble it represents a different situation since we won't place back the red marble into the bag, that's why each event decreases by one and each denominator too.

Therefore, the probability of selecting three red marbles without replacement is 15/33.

As we said before, in Part B, we had to multiply each probability for each time we select a red marble. It's important to notice that the numerators decreased by 1 (5,4,3) because each time we select a marble we won't place it back, that's the reason why the denominator also decreased by 1.
