Step 3: Define Pt. 2

Identify variables

Angle θ

Adjacent leg = 8

Hypotenuse = 4√13

Step 4: Find

Answer:

Solution given;

In right angled triangle with respect to θ

perpendicular: opposite side: [P]=12

base:adjacent:[b]=8

hypotenuse [h]=?

cosθ=?

According to the Pythagoras law

h²=p²+b²

h²=12²+8²

h=[tex] \sqrt{208}[/tex]

h=[tex] 4\sqrt{13}[/tex]

Now

we have

Cos θ=[tex]\frac{adjacent}{hypotenuse}[/tex]

Cos θ=[tex]\frac{8}{4\sqrt{13}}[/tex]

by rationalising it

Cos θ= [tex] \frac{2\sqrt{13}}{\sqrt{13}×\sqrt{13}}[/tex]

Cos θ= [tex] \frac{2\sqrt{13}}{13}[/tex]

is a required answer.

Answer:

C) The fossil is between 10 million and 50 million years old.

Step-by-step explanation:

Since Layer B is located between Layer A and C, option C is the only reasonable answer because Layer A is 50 million years old and Layer C is 10 million years old.

Given :

Jack bought 50 lbs of clay for his art projects. He used 13.2 lbs to make a sculpture, and 0.72 lbs for each mug.

To Find :

How many mugs did Jack make if he had 28.88 lbs of clay left over.

Solution :

Clay required to make 1 mug, r = 0.72 lbs.

Amount of clay left after making sculpture is, T = 28.88 lbs.

Now, number of clay mug Jack can make is :

[tex]n = \dfrac{28.88}{0.72}\\\\n= 40.11[/tex]

Since, number of mug cannot be in decimal, so we take the floor value.

Therefore, number of mug that can be prepared is 40 .

Answer:

9.24

Step-by-step explanation:

Formula Cylinder = πr² * h

Let's work backwards

Use 3.14 for π

3.14 * (6)² * h = 1044

3.14 * 36 * h = 1044

113.04 * h = 1044

h = 1044 ÷ 113.04

h ≈ 9.24

-Chetan K

Answer:

4/3π(0.973r³)

Step-by-step explanation:

Volume of a sphere = 4/3πr³

Given the radius of dodge ball rd = r

radius of tennis ball rt = 0.3r

Taking their difference

Volume difference  = 4/3πrd³ - 4/3πrt³

Volume difference  = 4/3π(r)³ - 4/3π(0.3r)³

Volume difference  = 4/3π(r³ - 0.027r³)

Volume difference = 4/3π(0.973r³)

Hence the differmce in volume is  4/3π(0.973r³)

Answer: Mean

Step-by-step explanation:

Mean is best used when the numbers in the data set are close together and the number of outliers are limited because outliers will either increase or decrease the mean such that it would not be a true representation of the data set.

In cases like the above however where the numbers are generally in the same range, the mean would provide a center measure that is the most representative because it would simply be a simple average of the numbers.

15.56 in.

Step-by-step explanation:

i'm pretty sure i did it right, but im not sure. i haven't done geometry in like over 2 years.

find the hypotenuse of the triangle with 7 in. and 12 in. as your legs with the Pythgorean theorem (a^2 + b^2 = c^2, c equals the hypotenuse)

use that number you just got (I got ) and use it as one leg, and 7 in. as the other leg, with d as your hypotenuse

use the Phythagorean theorem again to find d, andddd... you've got your answer!

Answer:

C) this is the false statement

Step-by-step explanation:

data set in list form:

35, 42, 45, 55, 65, 65, 68, 76, 85

Range: 85-35 = 50

Median: 65

Mean: 536/9 = 59.5

Mode:  65

The statement that is not true about this data set is C. The mean is 65 people.

This Stem-and-Leaf Plot shows the number of people who attended a local nine-day carnival.

The data set in list form:

35, 42, 45, 55, 65, 65, 68, 76, 85

Mean is the ratio of sum of the observations to the total number of observations.

Mean: 536/9 = 59.5

Median is such a number for the arranged data set(ascending or descending order) such that to its left and to its right belong same number of observations.

Median: 65

Range = Maximum value of the data set - Minimum value of the dataset

Range: 85-35 = 50

Mode is the number in given data that occurs frequently.

Mode:  65

L:W=(3/4):(1/2)  by convention we will express this ratio with integers...multiplying both fractions by 4 we get:

Area =3:2

Given:

The equation is:

[tex]y=-x+4[/tex]

To find:

The graph of the line that contains ordered pairs that are solutions of the given equation.

Solution:

We need to find the graph of the given equation.

We have,

[tex]y=-x+4[/tex]

At [tex]x=0[/tex], we get

[tex]y=-0+4[/tex]

[tex]y=4[/tex]

So, the x-intercept of the given equation is at point (0,4).

At [tex]y=0[/tex], we get

[tex]0=-x+4[/tex]

[tex]x=4[/tex]

So, the y-intercept of the given equation is at point (4,0).

From the given graphs it is clear that the line in option C has x-intercept at point (0,4) and y-intercept at point (4,0).

Therefore, the correct option is C.

Answer:

C

Step-by-step explanation:

20 ÷ 5 = 4

24 ÷ 6 = 4

28 ÷ 7 = 4

32 ÷ 8 = 4

So the correct answer is C

Answer:

[tex]C = 45 * 2\pi[/tex]

[tex]C = 90\pi[/tex]

Step-by-step explanation:

Given

[tex]h = 90[/tex] -- height of the wheel

Required

The expression for the distance traveled in 1 revolution

The height of the wheel implies that:

[tex]d =90[/tex] --- diameter equals height

The distance in 1 revolution is calculated by calculating the circumference of the wheel using:

[tex]C = 2\pi r[/tex] or [tex]C = \pi d[/tex]

Where

[tex]r = \frac{1}{2} * d[/tex]

[tex]r = \frac{1}{2} * 90[/tex]

[tex]r = 45[/tex]

So, we have:

[tex]C = 2\pi r[/tex]

[tex]C = 2\pi * 45[/tex]

[tex]C = 45 * 2\pi[/tex]

[tex]C = \pi d[/tex]

[tex]C = \pi * 90[/tex]

[tex]C = 90\pi[/tex]

Probability [chosen code starts with M and ends with E] = 0.05

Step-by-step explanation:

Given:

Total alphabet = A, F, E, R, and M

Creating name without repeat

Find:

Probability [chosen code starts with M and ends with E]

Computation:

Probability Name start with M = 1 / 5

Probability Name start with E = 1 / (5-1)

Probability Name start with E = 1 / 4

Probability [chosen code starts with M and ends with E] = Probability Name start with M x Probability Name start with E

Probability [chosen code starts with M and ends with E] = (1/5)(1/4)

Probability [chosen code starts with M and ends with E] = 1 / 20

Probability [chosen code starts with M and ends with E] = 0.05
