love history [14]

Answer:

$33\dfrac{1}{3}\ cm^2$

Step-by-step explanation:

If two corresponding sides of two similar triangles are 3cm and 5cm, then the scale factor is

$k=\dfrac{a_1}{a_2}=\dfrac{3}{5}.$

Two similar triangles have their area proportional with the scale factor of $k^2.$

Hence,

$\dfrac{A_1}{A_2}=k^2,\\ \\\dfrac{12}{A_2}=\left(\dfrac{3}{5}\right)^2,\\ \\\dfrac{12}{A_2}=\dfrac{9}{25},\\ \\A_2=\dfrac{12\cdot 25}{9}=\dfrac{100}{3}=33\dfrac{1}{3}\ cm^2.$

A parking garage charges $1.50 for the 1st hour of parking and $0.75 for each additional hour. What is the cost in dollars for p

QveST [7]

The equation you have to solve is 1.50 + (0.75 • 6). First, you solve what is in the parenthesis, 0.75 • 6 = 4.50. Now you simply add 1.50 and 4.50 to get $6, the total cost for 7 hours worth of parking.

A regular hexagonal prism has a volume of 160 cubic meters. Its base has a perimeter of 30 meters and an area of 64 square meter

valkas [14]

We know that

[volume of a regular hexagonal prism]=[area of the base]*height
height=volume/area of the base
h=160/64-----> 2.5 m

[surface area hexagonal prism]=2*[area of the base]+[perimeter of base]*h
[surface area hexagonal prism]=2*[64]+[30]*2.5----> 203 m²

the answer is
203 m²
