Convert all the numbers to real numbers:

6√3 = 10.3923

(3.5)^2 = 12.25

√75 = 8.660

9.8 = 9.8

57/5 = 11.4

A) Now order from largest to smallest:

(3.5)^2, 57/5, 6√3, 9.8, √75

B) We found the order by solving the equations to get real numbers.

Since the numbers are multiplied by a negative number, the greatest number would be the smallest number because it would be closer to zero.

The order would be the reverse of part A:

x√75, 9.8x, 6x√3, 57x/5, x(3.5)^2

D) I replaced x with -1 and calculated for real numbers. All the values were the same as A except they were the negative value.

An architect in Brussels measures something to be 2.5 feet (using the Brussels measurement). How many feet is this in Aalst (usi

borishaifa [10]

Answer:

$2.487F$

Step-by-step explanation:

From the question we are told that

Architect Measures 2.5 feet (using the Brussels measurement)

Generally in Brussels $1F=275.75mm$

Therefore

$2.5F=689.375mm$

Generally in Aalst $1F=277.2mm$

Therefore Mathematically converting to feet in Aalst measurement we get

$689.375mm*\frac{1}{277.2} =2.487F$

Which set of lengths are the side lengths of a right triangle? (9,15,17) (14,23,25) (20,30,40) (15,36,39)

goldfiish [28.3K]

Answer:

(15, 36, 39)

Step-by-step explanation:

Using pythagoreas formula: A^2 * B^2 = C^2

so a=15, b=36, c=39

15^2+36^2=39^2

Answer:

a. $\frac{\textbf{17}}{\textbf{4}}$

b. $\frac{\textbf{3}}{\textbf{8}}$

Step-by-step explanation:

a. $\textbf{3} \hspace{1mm} \textbf{+} \hspace{1mm} \textbf{1}\frac{\textbf{1}}{\textbf{4}}$

A mixed fraction of the form $a\frac{x}{y} = a + \frac{x}{y}$

$\therefore 3 + 1\frac{1}{4} = 3 + 1 + \frac{1}{4}$

$= 4 + \frac{1}{4}$

$= \frac{\textbf{17}}{\textbf{4}}$

b. $\textbf{2} \hspace{1mm} \textbf{-} \hspace{1mm} \textbf{1}\frac{\textbf{5}}{\textbf{8}}$

A mixed fraction of the form $-c\frac{a}{b} = - c - \frac{a}{b}$

$\therefore 2 - 1\frac{5}{8} = 2 - 1 - \frac{5}{8}$

$= 1 - \frac{5}{8}$

$= \frac{8 - 5}{8}$

$= \frac{\textbf{3}}{\textbf{8}}$

Hence, the answer.

The length of each side of a square is 6 feet more than the length of a side of a regular Octagon. The perimeter of the square i

goldfiish [28.3K]

Answer:

square: 12 ft sides
octagon: 6 ft sides

Step-by-step explanation:

This problem can be worked in your head.

If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.

We can let s represent the side length of the octagon. Then we have ...

8s = perimeter of octagon

4(s +6) = perimeter of square

These are equal, so ...

4(s +6) = 8s

s +6 = 2s . . . . . . divide by 4

6 = s . . . . . . . . . . subtract s

The octagon has 6-ft sides; the square has 12-ft sides.
