Kobotan [32]

Answer:

Steve put 1/8 of the box of baking soda in each one of the five bottles to make them bubble up like volcanoes.

Step-by-step explanation:

As "Steve performed the chemistry experiment in which divided 5/8 of a box of baking soda evenly among the five bottles...", So we only have to make a simple division, therefore $\frac{5}{8}Box \div 5 Bottles=\frac{5}{8 \times 5}Box/Bottle=\frac{1}{8} Box/Bottle$ , so Steve put 1/8 of the box of baking soda in each one of the five bottles.

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

<em>Find the scale factor</em>

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

<em>Find the area of the larger figure</em>

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

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

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

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

Please help with question 17! Thanks<3

krek1111 [17]

Answer:

36 km/h

Step-by-step explanation:

$\frac{100\textrm{ m}}{10\textrm{ sec}}\times\frac{60\textrm{ sec}}{1\textrm{ min}}\times\frac{60\textrm{ min}}{1\textrm{ hr}}=\frac{36000\textrm{ m}}{1\textrm{ hr}}$

$\frac{36000\textrm{ m}}{1\textrm{ hr}}\times\frac{1\textrm{ km}}{1000\textrm{ m}}=\frac{36\textrm{ km}}{1\textrm{ hr}}$
