What happens to the surface area of a rectangular prism when each of the dimensions is doubled? (1 point) i?

1 answer:

5 0

The surface area will be 4 times the original size. Here is why: You are doubling each dimension, and area is a 2 dimensional measurement. Because of this whatever you are doing to the length of the side will happen 2 times. In this case it would be x2 x2 which equals 4. You can provide evident by using a cube. The surface area of a cube with side lengths of 1 would be 1 x 6=6 square inches. If you double the side length, it would be 4 x 6= 24 square inches.

What is the percentage between 1192.64 and 819.73

Licemer1 [7]

1192.64-819.73 is 372.91

so... if we take 1192.64 to be the 100%, how much is 372.91 in percentage then?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1192.64&100\\
372.91&p
\end{array}\implies \cfrac{1192.64}{372.91}=\cfrac{100}{p}\implies p=\cfrac{372.91\cdot 100}{1192.64}$

Help me please thank you

Answer:

22 m^2

Step-by-step explanation:

The area of the bottom rectangle is A = l*w

The length is 8 and width is 2

A = 8*2 =16

The area of the top rectangle is A = l*w

The length is 3 and width is 2

A = 3*2 =6

Adding the areas together

A = 16+6 = 22

If I rencently decreased my average number of products sold per week by 15% I now sell an average of 21.25 products per week. Pr

VladimirAG [237]

Alright, lets get started.

Suppose previously I was selling product per week = x

As per question, I have decreased my average number of product by 15 %

Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x

So, the new average product = x - 0.15 x = 0.85 x

As per given question, the new average product = 21.25

0.85 x = 21.25

Dividing by 0.85 in both sides

0.85 x / 0.85 = 21.25 / 0.85

x = 25

Hence it means, 25 products were selling previuosly. : Answer

Hope it will work :)

Answer:

x = 5/4

Step-by-step explanation:

√2+√2+√2+√2 = 2^x

4√2 = 2^x

4√2 = $2^{\frac{5}{2} }$ = $2^{x}$

x = 5/2
