The perimeter of the original rectangle is ______

sergey [27]

Answer:

perimter of original rectangle = 17. 6 mm
side length of the enlarged rectangle = 23. 22 mm
perimeter of the enlarged rectangle = 95. 04 mm

Step-by-step explanation:

PERIMETER OF ORIGINAL RECTANGLE

Length of original rectangle = 4.5 mm
Width of original rectangle = 4.3 mm

perimeter = 2 × ( length + width)

= 2 × ( 4.5 + 4.3)

= 2 × 8.8

= 17. 6 mm

SIDE LENGTH OF ENLARGED RECTANGLE

Width of original rectangle = 4. 5 mm
Width of enlarged rectangle = 24.3 mm

Enlargement factor = 24.3 / 4.5

= 5.4

Length of original rectangle = 4.5 mm
Enlargement factor = 5.4

Side length of enlarged rectangle

= original length × Enlargement factor

= 4.3 × 5.4

= 23. 22 mm

PERIMTER OF ENLARGED RECTANGLE

= 2 × ( enlarged ength + enlarged breadth)

= 2 × (23. 22 + 24. 3 )

= 95. 04 mm

Point R divides in the ratio 1 : 3. If the x-coordinate of R is -1 and the x-coordinate of P is -3, what is the x-coordinate of

dimaraw [331]

Answer:

C. 5

Step-by-step explanation:

Point R divides the line segment PQ internally. The x-coordinate of the point which divides the line segment in ration m:n internally can be calculated as:

$x=(\frac{mx_{2}+nx_{1}}{m+n} )$

Here, x1 is the x-coordinate of 1st point, x2 is the x-coordinate of 2nd point, x is the x-coordinate of point dividing the segment. We have all the values except x2. Using the given values in above formula, we get:

$-1=\frac{x_{2}+3(-3) }{1+3} \\ \\-4=x_{2}-9\\\\ 5=x_{2}$

Thus the x-coordinate of point Q will be 5

The x-coordinate of Q is 5.

Determine whether the given positive or negative number is appropriate for the situation.

olya-2409 [2.1K]

Answer:

Yes, No, Yes, Yes, Yes!

Step-by-step explanation:

First Question:

That is correct because if you have $0 in your bank account and you withdraw $30 you will have -$30!

(And you are in debt which everyone hates!)

Second Question:

No, because that would be 125 above ground. You would need to say -125 instead of adding.

Third Question:

Yes! Let's say in the football game you had 70 yards, subtracting the 15 yards which you supposedly had lost would result in 55 yards therefore proving the fact that you did not progress but did the exact opposite!

Fourth Question:

Yes, because you are gaining more on your stock. This results in you getting more of a share in a company or product.

Fifth Question:

To be honest, I don't know if this: "0 feet could represent the altitude of a city that is located at sea level." is a question but I will answer it nonetheless!

Yes, because before right where the sea "starts" is what is called point 0. Meaning that, you are located at sea level!

If f(x) = 7(x - 1) + 8, find the value of f(1) answer fast.

VladimirAG [237]

F(x) = 7(x-1)+8, so f(1) = 7(1-1)+8 [sub the x value in] = 7-7+8 = 8
