Answer:

4.03 × 10⁷

Step-by-step explanation:

Estimate the product the given number.

(19)(2,120,400)

Product : 19×2120400

Product: 40287600

now write in scientific notation.

Scientific notation: $k\times 10^n$

where, k is between 0 to 9 and n any integers.

If decimal move from right to left then exponent positive.

40287600 = 4.03 × 10⁷

Estimate product of given number in scientific notation is 4.03 × 10⁷

ESTION 1 Sarah buys a new piano to the value of R 12 000. After 3 years it has a reduced value of R7 500. Determine the rate of

Ksju [112]

The rate of depreciation on the reducing balance method is $12,000.

The Piano value at the beginning of 2017 is $75,000 – $15,000 = $60,000. Depreciation for 2017 is $60,000 × 0.2 = $12,000.

This is because the rate of depreciation (20% in this case) is applied to the book value, which decreases year after year.

In 2016, the book value was $75,000, but by 2017 it had dropped to $60,000. It was reduced to $48,000 a year later. Keep in mind that the depreciation rate remains constant, but it is applied to a smaller amount (i.e., book value) each year.

As a result, the amount of depreciation per year is lower.

What is Reducing value ?

The reducing installment method is another name for the reducing balance method. It is especially useful for fixed assets whose value depreciates more rapidly in the first few years of use (e.g., cars, office equipment, and small machinery).The reducing balance method of depreciation is a method of accounting for assets over time. It is also known as declining balance depreciation or diminishing balance depreciation. It is charged at a set rate, similar to the straight line method (also known as the fixed instalment method or straight line.

Sali throws an ordinary fair 6 sided dice once.

xenn [34]

a) 1/6

b) 1/36

1H, 2H, 3H, 4H, 5H, 6H

1T, 2T, 3T, 4T, 5T, 6T

Step-by-step explanation:

The probability of a certain event A to occur is given by

$p(A)=\frac{a}{n}$

where

a is the number of successfull outcomes, in which event A occurs

n is the total number of possible outcomes

In this problem, the event is

"getting a 6 when throwing a dice once"

We know that the possible outcomes of a dice are six: 1, 2, 3, 4, 5, 6, so we he have

$n=6$

The successfull outcome in this case is only if we get a 6, so only 1 outcome, therefore

$a=1$

So, the probability of this event is

$p(6)=\frac{1}{6}$

In this case instead, we are throwing the dice twice.

The two throws of the dice are independent events (one does not depend on the other): the probability that two independent events A and B occur at the same time is given by the product of the individual probabilities,

$p(AB)=p(A)\cdot p(B)$
