The scale of a map says that 2 cm represents 10 km. What is the actual number of kilometers that is represented by 6 centimeters on the map?

Answers

Answer:

6 times 10 to the minus 5

6 cm on the map represents 30 kilometers in reality, with a scale of 2 cm representing 10 km.

In the given map, the scale is 2 cm represents 10 km.

Each centimeter on the map represents 5 km (10 km divided by 2 cm).

We can use the scale of the map, which states that 2 cm represents 10 km, to determine the precise number of kilometers that 6 centimeters on the map represent.

If 2 cm represents 10 km, then 1 cm represents 10 km / 2 cm = 5 km.

6 centimeters on the map represent 6 cm × 5 km/cm = 30 kilometers in reality.

Write down in terms of n an expression for the nth term of the following sequence 12,10,8,6,4

Answers

Answer:

n-2

Step-by-step explanation:

there is an obvious pattern. Such sequences can be expressed in terms of the nth term of the sequence. In this case, the nth term = 2n. To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8. The common difference is -2, so the formula for the nth term is 12-2(n-1).

This can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12.

The 5th term is 14-10=4; the 6th is 14-12=2. And so on. This is the formula The expression for the total number of tiles in the nth term is the sum of the areas of the rectangles, n2 + n(n – 1) + 2, which can be simpli- fied to 2n2 – n + 2. quadratic sequences with visual models these are just examples: The nth odd number is given by the formula 2*n-1.
In linear sequences only, the 'nth-term rule' gives the value of any term in that sequence at position 'n'. It is written as 'xn ± y' where x = the constant difference between term values and y is a particular number. The rule allows you to work out the terms of a sequence. An arithmetic progression is a sequence where each term is a certain number larger than the previous term. The terms in the sequence are said to increase by a common difference, d. For example: 3, 5, 7, 9, 11, is an arithmetic progression where d = 2. The nth term of this sequence is 2n + 1.

how do I find the value of x so f(x)=7

Answers

Answer:

x=5

Step-by-step explanation:

Here we are given with a graph.

we have been asked to find the value of x for which

As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.

Hence we get x=5, then f(x)=7.

Which functions represent the arithmetic sequence 8, 1.5, –5, –11.5 . . . ? Check all that apply.
f(n) = –6.5n + 14.5
f(n) = –1.5n + 9.5
f(n) = 6.5n + 1.5
f(1) = 8, f(n + 1) = f(n) – 6.5
f(1) = 8, f(n + 1) = f(n) – 1.5
f(1) = 8, f(n + 1) = f(n) + 6.5

Hi :)

A) 4x = 48: x= 12
B) 2x -6 = 18 x=12

4x - 12 = 36

Add 12 to both sides
4x=36+12

Add 36 and 12 to get 48
4x=48

Divide both sides by 4
x= 4/48

Divide 48 by 4 to get 12
x=12

Find the measure of the exterior angle.

Answers

Answer:

108°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

2a is an exterior angle, thus

2a = a + 10 + 44 = a + 54 ( subtract a from both sides )

a = 54

Thus 2a = 2 × 54 = 108° ← exterior angle

Which value of x makes the equation -5x-(-7-4x) =-2(3x-4 true?

Answers

Answer:

x = 1/5

Step-by-step explanation:

Step 1: Write equation

-5x - (-7 - 4x) = -2(3x - 4)

Step 2: Solve for x

Distribute: -5x + 7 + 4x = -6x + 8Combine like terms: -x + 7 = -6x + 8Add 6x to both sides: 5x + 7 = 8Subtract 7 on both sides: 5x = 1Divide by 5 on both sides: x = 1/5

Step 3: Check

Plug in x to verify it's a solution.

-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)

-1 - (-7 - 4/5) = -2(3/5 - 4)

-1 - (-39/5) = -2(-17/5)

-1 + 39/5 = 34/5

34/5 = 34/5

Answers

Answer:

x = 20

Step-by-step explanation:

There are both consecutive interior angles and are supplementary.

The equation should be written like this:

5x + 50 + x + 10 = 180

Step 1: Simplify both sides of the equation.

5x + 50 + x + 10 = 180

(5x+x) + (50+10) = 180 (Combine Like Terms)

6x + 60 = 180

Step 2: Subtract 60 from both sides.

6x + 60 − 60 = 180 − 60

6x = 120

Step 3: Divide both sides by 6.

[tex]\frac{6x}{6} = \frac{120}{6}[/tex]

x = 20

The midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).

What is a midpoint?

A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.

The midpoint is calculated by using the formula:- ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2.

Given points are R(-3,3) and S(1,6). The midpoint of the given points are calculated as below:-

M = (-3+1 ) / 2 , ( 3 + 9 ) / 2

M = ( -1,4.5)

Therefore, the midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).
