The area ratio of two similar soilds is 169:289 if the volume of the smaller solid is 689,858 cm what is the volume of the large

Rus_ich [418]

Answer: $1,542,682\ cm^3$

Step-by-step explanation:

Given

The ratio of two similar figures is 169:289

Suppose, their length ratio is x:y

$\therefore \dfrac{x^2}{y^2}=\dfrac{169}{289}\\\\\Rightarrow \dfrac{x}{y}=\dfrac{13}{17}$

Similarly, cube of the ratio is equal to the volume ratio

$\Rightarrow \left(\dfrac{13}{17}\right)^3=\dfrac{689,858}{V}\\\\\Rightarrow V=689,858\times \dfrac{17^3}{13^3}\\\\\Rightarrow V=314\times 17^3\\\\\Rightarrow V=1,542,682\ cm^3$

Thus, the volume of the larger solid is $1,542,682\ cm^3$

A tissue can be 0.000075 meters thick.

Setler [38]

Answer:

The required expression is $7.5\times 10^5$

Step-by-step explanation:

Consider the provided information.

A tissue can be 0.000075 meters thick and we need to represent it into scientific notation.

Steps to write a number in scientific notation.

Move the decimal place to the right so that the new number from 1 up to 10.

Determine the exponent, the exponent is the number of times you moved the decimal.

Now, consider the number 0.000075

Move the decimal point to 5 place right so that the new number from 1 up to 10.

Now, put the exponent the number of times you moved decimal. $7.5\times 10^5$

Hence, the required expression is $7.5\times 10^5$

Let f(x)=4x+7 and g(x)=3x-5. find (fog)(-4) A. -9 B. -61 C. -32 D. -17

vovikov84 [41]

Answer:

Step-by-step explanation:

To evaluate (f ￮ g)(- 4), first evaluate g(- 4) then substitute this value into f(x)

g(- 4) = 3(- 4) - 5 = - 12 - 5 = - 17, then

f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B
