(a) The perimeter of a rectangular parking lot is 370 m.

1 answer:

3 0

Perimeter = 2(length + breadth)
370 = 2 ( 98 + b)
370/2 = 98 + b
185. = 98 +b
b = 185 - 98
b. = 87
Therefore breadth = 87 sq m

The domain of a function are the possible input values of the function.

The domain of the function is (d) Whole numbers

First, we identify the start and end values of x on the graph.

We have:

$Start = 0$

The graph has no end; so:

$End = \infty$

This means that the domain of the graph is $(0,\infty)$

The number of times one can visit the pool cannot be decimal.

Hence, the domain of the function is whole numbers

At its lowest point the Euro tunnel is 115m below sea level. At this point, the tunnel is 50m below the sea bed. How deep is the

sweet-ann [11.9K]

Euro tunnel : - 115 (115 m below sea level of 0)

-115 = S - 50
-115 + 50 = S
- 65 = S....the sea bed is -65 m (or 65 m below sea level

are any two regular polygons similar. The area of the smaller figure is about 390 cm^2. choose the best estimate of the area of

galben [10]

Answer:

The best estimate of the area of the larger figure is $693\ cm^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x-----> the corresponding side of the larger figure

y-----> the corresponding side of the smaller figure

$z=\frac{x}{y}$

we have

$x=12\ cm$

$y=9\ cm$

substitute

$z=\frac{12}{9}=\frac{4}{3}$ -----> the scale factor

step 2

Find the area of the larger figure

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z----> the scale factor

x-----> the area of the larger figure

y-----> the area of the smaller figure

$z^{2}=\frac{x}{y}$

we have

$z=\frac{4}{3}$

$y=390\ cm^{2}$

substitute and solve for x

$(\frac{4}{3})^{2}=\frac{x}{390}$

$(\frac{16}{9})=\frac{x}{390}$

$x=390*16/9=693.33\ cm^{2}$
