Mathematics
1 answer:
sweet [91]3 years ago
3 0

Answer:

c

Step-by-step explanation:

using the law of logarithms

logx^{n} ⇔ nlogx

given 5((10)^{4x} = 75 ( divide both sides by 5 )

(10)^{4x} = 15 ( take log of both sides )

log10^{4x} = log15

4xlog10 = log15 ← log10 = 1

4x = log15 ( divide both sides by 4 )

x = \frac{log15}{4} → c

The missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4 and the missing expression should be for Step 6 is 56 - 4.1

<h3>Part A: Explain what the missing expression should be for Step 3</h3>

To do this, we make use of the expression in step 2

The expression in step 2 is

[(5^2 + 3)/0.5] - 16.4 ÷ 4

The next step at this stage is to evaluate the expression 5^2

So, we have:

[(25 + 3)/0.5] - 16.4 ÷ 4

Hence, the missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4

<h3>Part B: Explain what the missing expression should be for Step 6.</h3>

To do this, we make use of the expression in step 5

The expression in step 5 is

56 - 16.4 ÷ 4

The next step at this stage is to evaluate the expression 16.4 ÷ 4

So, we have:

56 - 4.1

Hence, the missing expression should be for Step 6 is 56 - 4.1

When the vat rate is 15% a customer pays 1610 to buy an electric iron .find the cost of the iron without vat (solve by video)
Schach [20]

Answer:

Cost without vat is 1,368.5

Step-by-step explanation:

Here, we want to know the cost of the iron without the vat.

From the question , we can see that 15% VAT brought the cost to 1610.

This means that the original cost without vat is 100% -15% = 85% of the total

Thus;

85/100 * 1610 is the cost without vat

And that is;

136850/100 = 1,368.5
