Mathematics
1 answer:
PtichkaEL [24]3 years ago

Answer:

3

Step-by-step explanation:

\sqrt{12} =3.46 (2 decimal places)

If you want to arrange the tiles into a square, you will need 3.46 in each row/column.

This is physically impossible, hence you round it down to 3.

(If you round it up, you won't have enough tiles since 4*4=16)

Thus, the square area will be 3*3=9

Tiles left: 12-9=3

Can anyone explain these?
Paul [167]
The perimeter , width and length are all one dimensional so the preimeter of the resulting rectangle  will be 2.5 * 36 = 90.

The area  is 2 dimensional  whereas the vase and height are one dimensional so the area will be increased by a factor of 5^2  ( or 25)
New  rea =  36*25 =  900

solids are 3 dimensional  so the ratio of thereir volumes is  5^3 : 3^3
= 125:27

to answer the last 2 use the formula Volume = pi r^2 h  where r = radius and h = height of a cylinder

Find the system of inequalities which represents the shaded region on the coordinate plane.
dybincka [34]

Answer:

given, y≥2x+1 and

y>

2

1

x−1

first, draw the graph for equations y=2x+1 and y=

2

1

x−1

for y=2x+1

substitute y=0 we get, 2x+1=0⟹x=−0.5

substitute x=0 we get, y=1

therefore, y=2x+1 line passes through (0.5,0) and (0,1) as shown in fig.

Hence, y≥2x+1 includes the region above the line.

for y=

2

1

x−1

substitute y=0 we get,

2

1

x−1=0⟹x=2

substitute x=0 we get, y=−1

therefore, y=2x+1 line passes through (2,0) and (0,-1) as shown in fig.

Hence, y>

2

1

x−1 includes the region above the line.

the intersection region is the shaded region as shown in above figure which includes I, II and III quadrants.

Therefore, quadrant IV has no solution please make as brainlelist
