Answer:

Hope it helps

Step-by-step explanation:

Area of tile => L=13cm B=7 A=l*b 13*7 =91cm^2 Area of plot => L=520vm B=140cm A=l*b 520*140 = 72800cm^2 No of tiles to fit = area if plot /area of tile 72800/91 =800

Answer:

Step-by-step explanation:

800 tiles

Step-by-step explanation:

Area of the tiles = Length × Breadth

= 13 × 7

= 91 cm²

Area of the rectangular region = Length × Breadth

= 520 × 140

= 72800 cm²

Therefore the number of tiles needed to cover the rectangular region

= Area of the rectangular region ÷ Area of the tiles

= 72800 cm² ÷ 91 cm²

= 800 tiles

Hope it helps

2=ln(x+7) solve for x
maria [59]

Answer:

e^2 -7 = x

Step-by-step explanation:

2=ln(x+7)

Raise each side to the base of e

e^2 = e^ln (x+7)

The e^ln cancel

e^2 = x+7

Subtract 7 from each side

e^2 -7 = x +7-7

e^2 -7 = x

Geometry math question please help
Fed [463]

First you need to find the sum of all the interior angles using the formula (n-2)*180, where n is the number of sides.

There are 6 sides to this figure so the interior angles need to equal (6-2)*180 = 4*180 = 720.

Now add all the given angles together: 2x + 3x + 3x + 3x +3x +2x = 16x

Now we know 16X = 720

Find X by dividing both sides by 16:

X = 720 / 16

X = 45

Now we know X, so to find E, replace X with 45 and multiply by 3:

3X = 3(45) = 135.

E = 135. The answer is D.
