What is 175% of 8000? Round to the nearest hundredth (if necessary).
igomit [66]

Answer: 175% of 8000 is equal to 14000.

Step-by-step explanation:

We know that to convert a percentage into fraction or decimal , we divide it by 100 .

Also, if find <em>x% of y</em> , then on next step we change '%' sign by \dfrac{1}{100} and  'of ' by Multiply sign (x).

Given problem : 175% of 8000

which can be re-written as: \dfrac{175}{100}\times8000

=\dfrac{175\times80}{1}\\\\=14000 (On solving)

i.e. on solving 175% of 8000, we get 14000

Therefore, 175% of 8000 is equal to 14000.

A rectangular photograph is nine centimeters wide and fourteen centimeters long. The photograph is enlarged by increasing the le
koban [17]

Answer:

Width=13cm

Length=18cm

Step-by-step explanation:

Width of the Initial Photograph=9cm

Length of the Initial Photograph=14cm

If width and length are increased by an equal amount, say x

New Width=9+x

New Length=14+x

Area of the new photo is 108 square centimeters greater than the area of the original photo.

Area of Original Photo=14*9=126cm²

Aeea of the New Photo=126+108=234cm²

Therefore:

(9+x)(14+x)=234

126+9x+14x+x²-234=0

x²+23x-108=0

x²+27x-4x-108=0

x(x+27)-4(x+27)=0

(x+27)(x-4)=0

x+27=0 or x-4=0

x=-27 or x=4

Since x≠-27

x=4cm

The dimensions of the new photo are:

Width=9+x=9+4=13cm

Length=14+x=14+4=18cm
