Area of base = 1/2 x 4 x 3.5 = 7 m²

Perimeter of the base = 4 + 4 + 4 = 12 m

Surface area = 7 + 7 + 12 x 11 = 146 m²

Answer: 146 m²

padilas [110]

Answer:

  • largest: R
  • smallest: K

Step-by-step explanation:

The slope of the graph at x=0 is related to the value of b. It is also proportional to the value of <em>a</em>, which is the same for all but curve B. The red curve R has the largest slope at x=0, (much larger than 3/4 the slope of curve B), so curve R has the greatest value of <em>b</em>.

Similarly, the smallest value of <em>b</em> will correspond to the curve with the smallest (most negative) slope. That would be curve K. Curve K has the smallest value of <em>b</em>.

3. Ravi is covering a table top in mosaic tiles that
Zinaida [17]

Answer:

432 tiles

Step-by-step explanation:

First, convert the dimensions of the table to inches.

There are 12 inches in a foot, so multiply 1.5 and 2 by 12.

1.5(12) = 18

2(12) = 24

So, the dimensions of the table in inches are 18 by 24.

Find the area of the table using the formula, A = lw

A = lw

A = (18)(24)

A = 432

So, the area is 432 square inches.

Since each tile is one square inch, the table will fit 432 of these.

So, Ravi will need 432 tiles.
