What you would do is X/15 and 20/100 Now cross multiply so x100 = 15 x 20 15 x 20 = 300, but you need to have x by it self so 300/100 = 3

Hope I said everything right and make sure to double check my math. Have a great day!

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.

The function g(x) = –3x2 – 36x – 60 written in vertex form is g(x) = –3(x + 6)2 + 48. Which is one of the transformations applie
nikklg [1K]
The general vertex form is this:
v(x) = a (x-h)2 + k
where (h,k) is the coordinates of the of vertex.
and a indicates the widening or shrinking of the function compared to another parabolic function. If a become bigger, the graph becomes narrower. If a becomes negative, the graph is reflected over the x-axis.

Comparing f(x) = x2 with g(x) = -3(x+6)2 + 48, we have the following transformations:
The graph is reflected over the x-axis
The graph is made narrower.
The graph is shifted 6 units to the left.
The graph is shifted 48 units up.

From the choices we only have:
<span>The graph of f(x) = x2 is made narrower</span>
