A new television set was recently purchased for the common room in a residence hall for $436.80 including tax the tax rate is 4%

garri49 [273]

Answer:

The price of the television before taxes is $420

Step-by-step explanation:

* Lets explain how to solve the problem

- The purchased price = cost price + taxes

- A new television set was recently purchased for the common room

in a residence hall for $436.80

- This price including tax

- The tax rate is 4%

- We need to find the price of the television before taxes

* Lets solve the problem

- Assume that the price of the television before tax is 100%

∵ The tax rate is 4%

∵ The price after tax = price before tax + tax

∵ The price before tax = 100%

∴ The price after tax = 100% + 4% = 104%

∵ 104% equivalent to $436.80

∴ 100 ⇒ ?

104 ⇒ 436.80

- By using cross multiplication

∴ ? = $\frac{(436.80)(100)}{104}=420$

∴ The price of the television before taxes is $420

What are the sides of a rectangular prism increased by if the volume increases from 54 mm3 to 3456 mm3?

kotykmax [81]

Answer:

The sides of the original rectangular prism have been increased by a scale factor of 4

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z----> the scale factor

x---> volume of the increased rectangular prism

y---> volume of the original rectangular prism

$z^{3}=\frac{x}{y}$

substitute

$z^{3}=\frac{3,456}{54}=64$

$z=4$ -----> the scale factor

therefore

The sides of the original rectangular prism have been increased by a scale factor of 4

Find the sum.

bezimeni [28]

D. Start Fraction 19 over 35 End Fraction

the denominators need to be equal to add so 1/7 converts to 5/35 and 2/5 converts to 14/35

so 5/35 + 14/35 = 19/35
