AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Novosadov [1.4K]

Two similar prisms have proportional dimensions. Find the ratio between lengths of these prisms:

$k=\dfrac{7}{5}$ .

The ratio between volumes of similar prisms is

$\dfrac{V_{large}}{V_{small}}=k^3$ .

If volume of small prism is 50 cub. m, then

$\dfrac{V_{large}}{50}=(\dfrac{7}{5} )^3=\dfrac{343}{125},\\V_{large}=\dfrac{343\cdot 50}{125} =137.2$ cub. m.

Answer: 137.2 cub. m.

If 75% of x is 150, what is the value of x?

vagabundo [1.1K]

I'm not sure if this is correct but you would put it into an equation while you solve for X. so 0.75x=150 or equivalently would be like (3/4)x=150 Then after that you would divide both sides by 0.75 or 3/4

If f(x) = x + 7 and g(x)=1/x , what is f(g(x)) ?

Usimov [2.4K]

Answer:

f(g(x)) = $\frac{1}{x} + 7$

Step-by-step explanation:

If f(x) = x + 7 and g(x)=1/x

f(g(x)), plug in g(x) in f(x)

g(x) = 1/x

first we plug in 1/x for g(x)

f(g(x)) = $f(\frac{1}{x})$

Plug in 1/x for x in f(x)

f(x) = x + 7

f(g(x)) = $f(\frac{1}{x})$ = $\frac{1}{x} + 7$
