Step-by-step explanation:

Finding the Number

To find the number, we have to translate the problem above to an algebraic equation. The algebraic equation refers to the statement of the equality of two algebraic expressions.

Equation:

Let "x" be the number.

4 is divided by a number - 4/x

3 divided by the number decreased by 2 - 3/x-2

"4 is divided by a number is equal to 3 divided by the number decreased by 2"

4/x = 3/x-2

Solution:

Cross multiply.

4/x = 3/x-2

x(3) = 4(x-2)

3x = 4x - 8

(Combine similar terms.)

3x - 4x = - 8

- x = - 8

- x/- 1 = - 8/- 1

x = 8

Final Answer:

8

Checking:

4/x = 3/x-2

4/8 = 3/8-2

1/2 = 3/6

1/2 = 1/2 ✔

What is the smallest power of 10 that exceeds this number 235,452
Oliga [24]

Answer:

10^{6}

Step-by-step explanation:

1. You have the following number given in the problem above:

235,452

2. As you can see, it is smaller than a number with seven digits as 1,000,000.

3. You can rewrite 1,000,000 as an integer power of 10, which must have the following form:

10^{n}

Where n is the exponent that indicates the number of times that 10 is multiplied by itself.

4. Therefore, you have:

1,000,000=10^{6}

A city has a population of 380,000 people. Suppose that each year the population grows by 6.5%. What will the population be afte
muminat
The growth formula is:

y = a•(1+x)^(t/p)

y is the end result

a is the initial amount

x is the percent growth as a decimal

t is the total amount of time

p is how often the growth occurred

Note that t and p both need to be the same units, whether that be seconds or days or months or years etc.

So,

y = 380000 • (1.065)^(10/1)

y = 380000 • 1.87713746527

y = 713312.236802

y = 713312
