Based on the inflation rate in the United States in 1949, the cost of the car at the end of the year would be<u> $1,470.</u>

<h3>What is the cost of the car at year's end?</h3>

The cost can be found by the formula:

= Cost x (1 + inflation rate)

The inflation rate is negative so solving gives:

= 1,500 x (1 - 2%)

= $1,470

What is the value of X?<br><br> 80 cm<br> 20 cm<br> 12 cm<br> 10 cm
dangina [55]

Answer:

x=12cm

Step-by-step explanation:

Triangle DEF is similar to triangle HGF.

Therefore the corresponding sides are proportional.

We can write the following equations for the corresponding sides.

\frac{DF}{HF}=\frac{EF}{GF}


This implies that,

\frac{16+40}{40}=\frac{x+30}{30}


This gives us,


\frac{7}{5}=\frac{x+30}{30}


We cross multiply to get,

7\times 30=5(x+30)


We divide through by 5 to get,


7\times 6=(x+30)

We multiply to get,

\Rightarrow 42=x+30

Grouping like terms gives,

\Rightarrow 42-30=x

We simplify to obtain,

\therefore x=12cm


The correct answer is C
