What percent of 25 is 14?

2 answers:

6 0

Part = 14
Total = 25
Percent = 56%

14 ÷ 25 = 0.56 × 100% = 56%.

14 is 56% of 25.

When the part and whole is given, divide the part by the whole to get the percentage.
When the part and corresponding percentage is given, divide the part by the corresponding percentage in decimal form to get the whole.
14/0.56 = 25
When the whole and percentage is given, multiply the whole by the percentage in decimal form to get the value of the part.
25 * 0.56 = 14

A function f is _____ on an open interval I if, for any choice of x1 and x2 in I, with 1 less than

Zepler [3.9K]

Answer:

If $f(x_1)\leq f(x_2)$ whenever $x_1\leq x_2$ f is increasing on I.

If $f(x_1)\geq f(x_2)$ whenever $x_1\leq x_2$ f is decreasing on I.

Step-by-step explanation:

These are definitions for real-valued functions f:I→R. To help you remember the definitions, you can interpret them in the following way:

When you choose any two numbers $x_1\leq x_2$ on I and compare their image under f, the following can happen.

$f(x_1)\leq f(x_2)$ . Because x2 is bigger than x1, you can think of f also becoming bigger, that is, f is increasing. The bigger the number x2, the bigger f becomes.

$f(x_1)\geq f(x_2)$ . The bigger the number x2, the smaller f becomes so f is "going down", that is, f is decreasing.

Note that this must hold for ALL choices of x1, x2. There exist many functions that are neither increasing nor decreasing, but usually some definition applies for continuous functions on a small enough interval I.

What is the difference in the surface area of two cubes, one with edge 15 and one with an edge of 12

Lilit [14]

Remark

A cube has six sides, all of them equal. The formula for 1 side is s^2. The formula for all six = 6s^2.

Step One

Find the surface area of the larger cube.

Area = 6 *s^2

s = 15

Area = 6 *15^2

Area = 6 * 225

Area = 1350

Step Two

Find the area of the smaller cube

Area = 6s^2

Area = 6 * 12^2

Area = 6 * 144

Area = 864

Step Three

Find the difference

Area1 - Area2 = difference

1350 - 864 = 486

The difference is area = 486 units^2 <<<<< Answer

There is a slightly shorter way. Take out the common factor of 6

Difference = 6 * (15^2 - 12^2)

Difference = 6 * (225 - 144)

Difference = 6 * (81)

Difference = 486

Some one please help me with these questions I’m struggling :(

Juliette [100K]

Answer: 6) 15 1/10

Step-by-step explanation:

Add the whole numbers and then find a common number for the bottom fraction. So that'd be ten. To get to ten from 2 you'd multiply by five then multiply the top number by five too. That gets you 5/10 and do the same for the other fraction. Get the bottom number to ten then whatever you multiply by do the same to the top. After doing that putting the fractions together which gets you 11/10. That'd make 1 1/10 so that makes it 15 instead of 14 whole

3ln(4x)=13

Kryger [21]

3 * ln 4x = 13

<=> 

ln 4x = 13/3 

<=> 

4x = e^(13/3) 

<=> 

x = e^(13/3) / 4 

<=> 

x ~ 19.05
