during a 20%of sale,the sale price of an mp3 alarm clock was 35.96 what was the regular price of the radio

babymother [125]

If 20% was taken off, that means that 35.96 is 80% of the original price.
35.96 = $\frac{80}{100}$
Now, we just need to put it into fractions, cross multiply, and divide to find the original price.
$\frac{35.96}{1} = \frac{80}{100} \
$
35.96×100 = 3596
1×80 = 80
3596÷80 = 44.95
Now, to make sure, we multiply 44.95 by 20%,
44.95×0.20 = 8.99
Subtract that from 44.95
44.95-8.99 = 35.96
That is the sale price of the alarm clock.
This means that yes, the regular price of the mp3 alarm clock was
$44.95

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10.

Margaret [11]

Answer:

Question 1 ) Difference of Volume = 112.25 cm³

Question 2) Volume = 6400π feet³

Step-by-step explanation:

<h3>As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.10. If the cans are currently 12 cm tall, 6 cm in diameter, and have a volume of 339.12 cm3, how much more will the new cans hold? Use 3.14 for π and round your answer to the nearest hundredth.</h3>

Diameter = 6 cm

Radius = 3 cm

Height = 12 cm

If we increase the dimension by 1.10, new dimesnions are:

Radius = 3 · 1.1 = 3.3 cm

Height = 12 · 1.1 = 13.2 cm

Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)(3.3²)(13.2)

Volume = 451.37 cm³

Difference of Volume = 451.37 cm³ - 339.12 cm³

Difference of Volume = 112.25 cm³

<h3>The circumference of a redwood tree trunk is 16π ft, and it is 100 ft tall. What is the approximate volume of the redwood tree trunk? </h3>

Circumference = 2πr = 16π = 2π(8) feet

Radius = 8 feet

Volume = Volume = (Area)(Height) = (πr²)(Height)

Volume = (π)((8²)(100)

Volume = 6400π feet³
