Answer:

The digit 3 represents a value of 30,000,000.

Step-by-step explanation:

Starting from the rightmost digit, each number is multiplied by 10 raised to an incrementing exponent beginning at zero. In detail:

Let the exponent be i

i = 0;

Value of digit 7 is v(7)

$v(7) = 7*10^{0} = 7$

i = 1;

Value of digit 5 is v(5)

$v(5) = 5*10^{1} = 50$

i = 2;

Value of digit 1 is v(1)

$v(1) = 1*10^{2} = 100$

i = 3;

Value of digit 5 is v(5)

$v(5) = 5*10^{3} = 5,000$

i = 4;

Value of digit 9 is v(9)

$v(9) = 9*10^{4} = 90,000$

i = 5;

Value of digit 6 is v(6)

$v(6) = 6*10^{5} = 600,000$

i = 6;

Value of digit 8 is v(8)

$v(8) = 8*10^{6} = 8,000,000$

At i = 7;

Value of digit 3 is v(3)

$v(3) = 3*10^{7} = 30,000,000$

This confirms the digit 3 holds a value of 30,000,000.

Madame Dubois bought 20 pearl necklaces for $500. Becoming bored quickly, she sold 3/4 of them at $40 each. She sold the rest at

Leona [12618]

$725, 3/4 of 20 equals 15 necklaces. 15 times 40 equals 600. Then, 5 times 25 results in 125. Finally, 125 plus 600 equals 725.

I=$720, P=$1000, r=9%<br> Find the amount of the time.

Leona [12618]

I = PRT....seeking T...rearrange......I / PR = T

I / PR = T
I = 720
P = 1000
R = 9% = 0.09
substituting values
720 / (1000)(0.09) = T
720 / 90 = T
8 = T <===

A home’s value increases at an average rate of 5.5% each year. The current value is $120,000. What function can be used to find

Svet_ta [12734]

Answer:

$f(x)=120000 \times (1.055)^{x}$

Step-by-step explanation:

The present value of the house is $120,000 and the interest rate is 5.5%, or 0.055.

We will utilize the following equation:

$f(x)=P \times (1+r)^{x}$

where $P$ represents the present value, $r$ symbolizes the interest rate, and $x$ refers to the number of years.

By inputting the values into the above equation, we can obtain:

$f(x)=120000 \times (1+0.055)^{x}$

$f ( x ) = 120000 \times ( 1.055 ) ^ { x }$

What is the factored form of a2 – 121?

AnnZ [12381]

Response:

The factored expression $a^2-121$ is $(a+11)(a-11)$ .

Detailed explanation:

Provided: $a^2-121$

Our goal is to express the given equation in a factored form.

Factoring pertains to rewriting an expression so that the product of its factors yields the original expression

Let’s consider the expression $a^2-121$ .

We recognize the algebraic identity $x^2-y^2=(x+y)(x-y)$

Thus, we have $a^2-121=a^2-(11)^2$ .

Matching with the above identity, we assign x= a, and b = 11, leading to

$a^2-(11)^2=(a+11)(a-11)$ .

Consequently, the factored expression $a^2-121$ is $(a+11)(a-11)$ .
