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:

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

Answer:

Step-by-step explanation:

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:

(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)

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:

(x-2)^2 + (y - 5)^2 = 16

Step-by-step explanation:

Given the standard form of an equation of a circle

(x-h)^2+(y-k)^2=r^2

If (h, k) = (5,2) and r = 4

Substitute

(x-2)^2 + (y - 5)^2 = 4^2

(x-2)^2 + (y - 5)^2 = 16

Hence the required equation is (x-2)^2 + (y - 5)^2 = 16

Answer:

1

Step-by-step explanation:

the probability is 1 because the ration of black to white is 1 to 2 so i guess she has 1 chance that it is black

Answer:

-5/2

Step-by-step explanation:

2x-10/4=3x

10/4=2x-3x

5/2=-x

x=-5/2

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

Answer:

a possible solution is (10,1)

Step-by-step explanation:

Here, we want to solve the given inequality and determine one possible solution

From the question, we have it that;

x + y ≤ 13

Mathematically, we have it that 1 dime is worth $0.1

A nickel is worth $0.05

0.1x + 0.05y ≥ 0.95

please check the attachment for the graph of both equations

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:

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
