The price of a fan is $15. This price is 27% lower than last week.
Goshia [24]

The price of fan was 20 Dollars 55 cents last week.

Step-by-step explanation:

Let,

The price last week = x

As the price is 27% lower than last week, therefore

(100%-27%) * Price last week = $15

73% * x = 15

Solving the percentage;

\frac{73}{100}*x=15\\ Multiplying\ both\ sides\ by\ 100\\100*\frac{73x}{100} = 15*100\\73x=1500\\Dividing\ both\ sides\ by\ 73\\\frac{73x}{73} = \frac{1500}{73} \\x= 20.55

The price of fan was 20 Dollars 55 cents last week.

the length , breadth and height of a cuboid is 2x^2y cm,5y^2z cm and 4z^2x cm. The volume of the cuboid is ...............
kondor19780726 [428]

For this case we have that by definition, the volume of a cuboid is given by:

V = L * A * h

Where:

L: It's the long

A: It is the width

h: It is the height

According to the problem data we have:

L = 2x ^ 2y \ cm\\A = 5y ^ 2z \ cm\\h = 4z ^ 2x \ cm

So, the volume of the cuboid is:

V = (2x ^ 2y) (5y ^ 2z) (4z ^ 2x)\\V = 10x ^ 2y ^ 3z (4z ^ 2x)\\V = 40x ^ 3y ^ 3z ^ 3

Finally, the volume of the cuboid is: V = 40x ^ 3y ^ 3z ^ 3

Answer:

V = 40x ^ 3y ^ 3z ^ 3

Can someone help me please​
ruslelena [56]

Answer:

3x - 14

Step-by-step explanation:

Perimeter = 2(length+width)

= 2[(½X-7) + (x)]

= 2[½x + x - 7]

= 2[1.5x - 7]

= 3x - 14
