Can someone help solve this?

Answer:

n = 2

Step-by-step explanation:

If two triangles are similar, their corresponding sides will be proportional.

Both the triangles in the given picture similar.

Therefore, by the property of similar triangles,

Corresponding sides of the given triangles will be proportional.

[tex]\frac{1}{2}=\frac{n}{4}[/tex]

n = [tex]\frac{4}{2}[/tex]

n = 2

Answer:

(x, y) → (–x, –y)

Step-by-step explanation:

Given

[tex]R_0, 180^{\circ}[/tex]

Required

Another way to write the above transformation

The above transformation means 180 degrees clockwise rotation.

When a coordinate point (x,y) undergoes this type of transformation, the new coordinate point becomes (-x,-y).

Hence, another way to write [tex]R_0, 180^{\circ}[/tex] is (x, y) → (–x, –y)

Given:

A student has 6 nickel 14 dimes and 8 quarter.

To find:

The ratio of the total number of coins to the number of nickels.

Solution:

We have,

Number of nickels = 6

Number of dimes = 14

Number of quarter = 8

Total number of coins = 6+14+8

                                     = 28

Now, the ratio of the total number of coins to the number of nickels is

[tex]Ratio=\dfrac{\text{Total number of coins}}{\text{Number of nickels}}[/tex]

[tex]Ratio=\dfrac{28}{6}[/tex]

[tex]Ratio=\dfrac{14}{3}[/tex]

[tex]Ratio=14:3[/tex]

Therefore, the  ratio of the total number of coins to the number of nickels is 14:3.

Answer:

The answer would be based off of how many miles the dad went so if he went to say 140 miles then it would be 2 hours.

Step-by-step explanation:

Just go to your calculator and divide how many miles he went by 70 then it will give you the amout of hours he went.

Have a great day! :)

Answer:

The area of the triangle is 48 square centimeters.

Step-by-step explanation:

The area of a triangle is base times height times a half. So the area of the triangle is 12 * 8 / 2 = 6 * 8 = 48 square centimeters.

Answer: 70 m

Step-by-step explanation:

The field described has the shape of a rectangle because one side is longer than the other.

The length that Ravi would have to walk therefore is the perimeter of this rectangle.

Perimeter = 2 × ( Length + Width)

= 2 × ( 15 + 20)

= 2 × 35

= 70 m

Answer:

No they aren't equivalent

Step-by-step explanation:

Let's take each expression

the first one is

- (12x+24) - 9x = -12x -24 -9x = -21x -24 = -3 (7x +8)

the second expression

-6 (x+1) = -6x-6

So they aren't equivalent

Answer:

3⁸ or 6561

Step-by-step explanation:

First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

There are no parentheses, so let's solve the exponents.

3² • 9³

3² = 9

9³ = 729

Your expression is:

9 • 729

Now let's multiply.

= 6561

This number can also be expressed with exponents.

Since 9 = 3², 9³ = 3²⁽³⁾

Now your expression is:

3² • 3²⁽³⁾

First, solve the exponents by multiplying.

3² • 3⁶

When you multiply two expressions with exponents that have the same base (3), you add the exponents.

3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸

3⁸ also equals  6561.

Your answer is 3⁸ or 6561.

Hope this helps!

Answer:

Step-by-step explanation:

we have the mean=13

(x+y+z)/3=13

x+y+z=39

range=highest value-lowest value=10

lets say x= highest value

y=lowest value

x-y=10

x=10+y

the numbers are 9,11,19

19-9=10 range

sum is 39

This is simple:

= 4x - 2y = 8

Put x = 0

= 4 ( 0) - 2 y = 8

= 0 - 2y = 8

= -2y = 8

= y = 8/-2

= y = - 4

So, the solution will be ( 0, -4)

= y = ½ x + 2

Put x = 0

= y = ½ × 0 + 2

= y = 0 + 2

= y = 2

So, the solution will be ( 0, 2 ).

Answer:

Step-by-step explanation:

Given

Points: (0,3) and (-4,-1)

Formula

x = 0 to find the y intercept

m = (y2 - y1)/(x2 - x1)

Solution

y2 = 3

y1 = - 1

x2 = 0

x1 = - 4

m = (3 - -1)/(0 - - 4)

m = 4/4

m = 1

You have y = mx + b so m = 1

the general equation becomes y = x + b

Use point (0,-4)

y = x + b

- 4 = 0 + b

b = - 4

y = x - 4
