a line

a ray

an angle

(No pic btw)

Answer:

Answer:

All of these can be contained in a plane.

Step-by-step explanation:

All of these can be contained in a plane.

A plane is extends infinitely in the x and y directions.

a point is a dot,

a line goes infinitely in two directions

a ray goes infinitely in one direction from a point

an angle is a corner. It is where two rays meet or where 2 lines meet or where 2 line segments meets

Answer:

Everything!

You can plot points, make lines wih those points, make rays with those lines, and make angles as well! All there is to it! (you can just mark the other person brainliest, I don't mind! Hope you have a good day!)

What is the value of b in the equation 3b + 2(b - 1) =8

Answer:

b = 2

Step-by-step explanation:

In order to find the value of b, we have to isolate b on one side of equation first

So,

Multiplying 2 with b-1

Adding 2 on both sides

Dividing by 5 on both sides

So the value of b is 2 ..

ANSWER

The value of b is 2

EXPLANATION

The given linear equation in b is

We expand to get:

We now group similar terms to obtain:

Combine the similar terms now to obtain:

Divide both sides by 5 to get:

This simplifies to:

Solve the following system of equations graphically. y - 4 = 0 2x - y - 2 = 0 What is the solution set?

Answer:

{}

Step-by-step explanation:

The given system of equations is;

and

We rewrite the equations in the standard form to get:

We now substitute equation (3) into equation (4) to get:

Group similar terms:

Divide both sides by 2

This implies that:

Therefore the solution set is:

x

PLEASE I NEED IT FOR TEST

Answer: 45

Step-by-step explanation:

A^2 + B^2 = C^2

27^2 + 36^2 = x^2

729 + 1296 = 2025

square root of 2025 = 45

X = 45

Many areas of Northern California depend on the snowpack of the Sierra Nevada Mountains for their water supply. If 300 cubic centimeters of snow will melt to 33 cubic centimeters of water, how much water does 600 cubic centimeters of snow produce? 16.5 cubic centimeters

66 cubic centimeters

72.6 cubic centimeters

5454 cubic centimeters

Answer:

Option B is correct.

Step-by-step explanation:

300 cm^3 of snow melts into 33 cm^3 water. We need to find how much water is produced if 600 cm^3 of snow is melt.

Solving using unitary method:

300 cm^3 of snow melts into water = 33 cm^3

1 cm^3 of snow melts into water = 33/300

600 cm^3 of snow melts into water = 33/300 *600

= 66 cm^3

So, Option B is correct.

F(x)= 7x + 9 g(x) = 7x - 4 the graph of g(x) is obtained by shifting down the graph of f(x

)

Answser: the graph of g(x0 is obtained by shifting down 13 units. the graph of f(x).

Explanation:

It is a rule that when you add a constant to a function the graph is shifted upward the number of units that the constant represent, when the constant is posivite, or downward the number of units that the constant represent, whtn the constant is negative.

So, the graph of any function h(x) + k, being k a constant, will be the graph of h(x) shifted k units upward (if k iis positive) or downward (if k is negative).

Then, you have to find how many units you have to add to f(x) = 7x + 9 to become the function g(x) = 7x - 4. That is, find k in:

7x + 9 + k = 7x - 4

⇒ k = - 4 - 9 = - 13.

So, you have that the graph of g(x) = 7x - 4 is found when you add - 13 to add - 13 to the graph of f(x) = 7x + 9.

Which, as explained before is shifting 13 units down.

1. Ramon spends 2/5 of his monthly income on rent, 1/5 of his monthly income on utilities, and 3/4 of the amount remaining on food and recreation. Ramon saves the rest. If the amount he saves each month is $193.50, what is Ramon’s monthly income?

Answer:

2/5 + 1/5 = (3/5) rent and utilities

(3/4) of (2/5) = food and recreation

(3/4) of (2/5) = 3/10

Savings = (5/5) -(3/5) -(3/10) = 1/10

So, if he is saving $193.50 then monthly income = $1,935.00

***** DOUBLE-CHECK ********

Rent & Utilities = (3/5) * 1,935.00 = 1,161.00

food and recreation = 3/10 * 1,935.00 = 580.50

Savings = $193.50

Total = 1,161.00 + 580.50 + 193.50 = $1,935.00

Correct!!

What is the percentile for data value 6 in the following data set? 4 13 8 6 4 4 13 6 4 13 2 13 15 5 9 4 12 8 6 13 40 25 35 62

Answer:

29th percentile.

Step-by-step explanation:

Let us arrange our given data from least to greatest order.

2, 4, 4, 4, 4, 4, 5, 6, 6, 6, 8, 8, 9, 12, 13, 13, 13, 13, 13, 15, 25, 35, 40, 62.

To find the percentile value of x we use formula:

We can see from our data set that there are 7 numbers less than 6 and total number of data points is 24.

Upon substituting our given values in above formula we will get,

Therefore, the percentile of data value 6 is 29th percentile.

Answer:

The answer is actually 35 not 29

Step-by-step explanation:

there are 20 numbers so it would be 7 divided by 20 which is .35 and .35 multiplied by 100 is 35...don't listen to the person before me they miscounted
