Answer:

144 m^3

Step-by-step explanation:

Please find attached the image of the prisms

Volume of a triangular prism = area of the base x height  of the prism

Area of the base = 1/2 ( base x height)

the two prisms are similar, thus, the dimensions of the bigger rectangle can be gotten from the ratio of the base of the smaller and bigger triangle

ratio of their dimensions = 6 / 1.5 = 4

the dimensions of the bigger triangle is 4 times that of the smaller triangle

height of the base of the prism = 1.5 x 4 = 6

Height of the prism = 2 x 4 = 8

Area of the base of the prism = (1/2) x 6 x 6 = 18 m^2

Volume of the prism = 18 x 8 = 144 m^3

If inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year, what would you expect to pa
tamaranim1 [39]

Answer:

$76.5

Step-by-step explanation:

We have been given that inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year. We are asked to find the price of pair of designer jeans this year.

An inflation of 2% will increase the price of pair of jeans by 2%, so price of pair of jeans this year would be $75 plus 2% of $75.

\text{Price of pair of jeans this year}=\$75+\$75\times\frac{2}{100}

\text{Price of pair of jeans this year}=\$75+\$75\times0.02

\text{Price of pair of jeans this year}=\$75+\$1.5

\text{Price of pair of jeans this year}=\$76.5

Therefore, the price of pair of jeans would be $76.5 this year.
