Answer:

$94.12

Step-by-step explanation:

If the original price is $90.5 then you would have to multiply

90.50*104%,you multiply 104% because 100% is sopposed to be the original price and the tax adds up the price by 4% so,

100%+4%=104%

104%*90.50=$94.12

The surface areas of two similar solids are 169 m2 and 81 m2. the volume of the larger solid is 124.92 m3. which proportion corr
ikadub [295]

By finding the scale factor, we will see that the volume of the smaller solid is 86.75 m³.

<h3>How to get the volume of the smaller solid?</h3>

If the solids are similar, then there is a scale factor between the two. Then the relation between the areas is equal to the scale factor squared, and the relation between the volumes is equal to the scale factor cubed.

This means that if the areas are 169 m² and 81 m², then we can write:

169 m² = (k²)*81 m²

Solving for k, we get:

k = √(169 m²/81 m²) = 1.44

Then if the volume of the large solid is 124.92m³ we can write:

124.92m³ = k³*V

Replacing k and solving for V we get:

124.92m³ = (1.44)³*V

(124.92m³/ (1.44)³) = V = 86.75 m³

How can you change the equation y = 2x + 3 to function notation?
qwelly [4]

Answer:

f(x)=2x+3

Step-by-step explanation:

The first thing that would need to be done is solving for y. This problem has already done this. The next step is to exchange y for f(x)

That is all. This would mean that the function notation for the equation would be: f(x)=2x+3
