Answer:

625 tiles

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total room floor area = 16 × 12 = 192

So, area of one third room = 192 × (1 ÷ 3)

Area of one third room = 64

Length of each tiles = 0.32

As it is a square tile, width = length, = 0.32

o, total area of each tile = 0.32 × 0.32 = 0.1024

So, number of tiles to cover 64 area of room = 64 ÷ 0.1024 = 625 tiles.

Hence, 625 tiles needed to cover one third of room.

Explanation:

Answer:

7[tex]\sqrt{3}[/tex]

Step-by-step explanation:

the altitude creates two congruent 30-60-90° triangles

the ratio of the sides in a 30-60-90°, respectively, are 1 : [tex]\sqrt{3}[/tex] : 2

therefore we can set up a proportion to find the side length:

let 'x' = side length of equilateral Δ

[tex]\sqrt{3}[/tex] / 1 = 21 / x

cross-multiply:

[tex]\sqrt{3}[/tex]x = 21

x = 21 / [tex]\sqrt{3}[/tex]

rationalize the denominator by multiplying numerator and denominator by [tex]\sqrt{3}[/tex]

21[tex]\sqrt{3}[/tex] / [tex]\sqrt{3}[/tex]·[tex]\sqrt{3}[/tex] = 21[tex]\sqrt{3}[/tex] / 3 or 7[tex]\sqrt{3}[/tex]

Answer:

[tex]0< b\leq 14.5[/tex]

Step-by-step explanation:

Let's set up our equation. We know that rectangles have two pairs of equal sides. We are also given that one pair of those sides is 1 unit longer than the other pair. Finally, we are told that the perimeter is at most 60 meters. 'At most' tells me to set up an inequality.

I'm going to set up two equations to solve this problem. First, let [tex]a[/tex] be the longer side and [tex]b[/tex] be the shorter side.

[tex]2a+2b\leq 60[/tex]

Next, because the sides are consecutive integers and [tex]b[/tex] is shorter, we can say that [tex]a-b=1[/tex].

We now have a system of equations. I will solve using substitution.

[tex]a-b=1\\a=b+1[/tex]

Substitute [tex]a[/tex] into the first equation.

[tex]2(b+1)+2b\leq 60[/tex]

Solve algebraically.

[tex]2b+2+2b\leq 60\\4b+2\leq 60\\4b\leq 58\\b\leq 14.5[/tex]

So, [tex]b[/tex] could be any integer between 0 (since distance cannot be negative) and 14.5, also written as [tex]0<b\leq 14.5[/tex].

I hope this helped!

Answer: No solution

Step-by-step explanation: there is not a single value of x that would make the equation true

Answer:

Your expression for 2(x - 3) would be 2x - 6 I'm not sure what the 2x + 5 is there for. Correct me if I'm wrong. If your trying to find the value of x you cannot find it. There is no solution to find the value of X.

Answer:

375

Step-by-step explanation:

If we say there were a adult tickets sold, we know that there were a + 68 student tickets sold.

a + a + 68 = 2a + 68

818 tickets were sold in total so

2a + 68 = 818

2a = 750

a = 750/2 = 375 adult tickets sold

Answer:

443

Step-by-step explanation:

So, what we basically know is the total number of tickets for adults and students altogether. In order to start this problem itself, it will require a subtraction.

So,

That's gonna be,

818 - 68= 750

For me, personally, I have a method that works for every question similar to this one. The concept is kinda weird ,yeah but it applies to all types of questions like this one.

It is

More than= Sub-add or Subadd

So, it's gonna be

this,

818 - 68= 750

750÷ 2 = 375

Number of tickets for adults will be= 375 + 68= 443

Answer:

([tex]\frac{18}{5}[/tex], [tex]\frac{16}{5}[/tex] )

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

x + 2y = 10 → (2)

Substitute y = 2x - 4 into (2)

x + 2(2x - 4) = 10 ← distribute and simplify left side

x + 4x - 8 = 10

5x - 8 = 10 ( add 8 to both sides )

5x = 18 ( divide both sides by 5 )

x = [tex]\frac{18}{5}[/tex]

Substitute this value into (1) for corresponding value of y

y = 2([tex]\frac{18}{5}[/tex] ) - 4 = [tex]\frac{36}{5}[/tex] - [tex]\frac{20}{5}[/tex] = [tex]\frac{16}{5}[/tex]

solution is ([tex]\frac{18}{5}[/tex], [tex]\frac{16}{5}[/tex] )

Answer:

Side A = 25 in

Side B = 14 in

Side C = 17 in

Step-by-step explanation:

Perimeter of a triangle = 56 in

Side B = x

Side A = 2x - 3

Side C = 1/2x + 10

Perimeter of a triangle = side A + Side B + side C

56 = (2x -3) + x + (1/2x + 10)

56 = 2x - 3 + x + 1/2x + 10

56 + 3 - 10 = 2x + x + 1/2x

49 = 3 1/2x

Note: 3 1/2x = 3.5x

49 = 3.5x

x = 49/3.5

x = 14 in

Side B = x = 14 in

Side A = 2x - 3

= 2(14) - 3

= 28 - 3

= 25 in

Side C = 1/2x + 10

= 1/2(14) + 10

= 7 + 10

= 17 in
