Log8(216)+[log(42)_log(6)]÷log(49)

makkiz [27]

Answer:

3 log (3) + 1/2

Step-by-step explanation:

log8(216) + [log(42) - log(6)] ÷ log(49) =
log (216)/ log (8) + [log (7) + log (6) - log (6)] ÷ 2 log (7) =
3 log (3) log (2) / 3 log (2) + log (7) / 2 log (7) =
3 log (3) + 1/2

The price of a pedicure decreases by 4.2% from £36 on promotion.

maria [59]

A) 95.8 % of £36 will be the new price

B) The answer to part A as a decimal is £34.488

C) The new price is £34.488

<h3>Solution:</h3>

Given that the price of a pedicure decreases by 4.2% from £36 on promotion

A) What percentage of £36 will the new price be ?

Given that £36 is decreased by 4.2 %

New price = 36 – 4.2% of 36

$\begin{array}{l}{\text { New price }=36-\frac{4.2}{100} \times 36} \\\\ {\text { New price }=36-1.512} \\\\ {\text { New price }=34.488}\end{array}$

Now we have to find what percentage of £36 will the new price be

x % of 36 = 34.488

$\frac{x}{100} \times 36 = 34.488\\\\x = \frac{34.488 \times 100}{36} = 95.8 \%$

B) Write your answer to part a as a decimal.

Now, we have to find the new price in decimal form.

$\begin{array}{l}{95.8 \% \times 36 \rightarrow \frac{95.8}{100} \times 36} \\\\ {\rightarrow 0.958 \times 36=34.488}\end{array}$

C) Work out the new price.

As we calculated, the new price is £34.488

Roy purchased different cardboard pieces that had the same ratio of the length to the width. The table below shows the length an

Alexxandr [17]

6 to 5, 12 to 10, 18 to 15, 24 to 20, x to 25

Let's take a look at x/25 ratio, which has to be equal 6/5.

$\frac{x}{25}= \frac{6}{5} \\
25*6=5x\\
5x=150\\
x=30$

The answer is 30 inches.

Akayo claims that there are centers of dialstiond through ehich a dialation of line n by a factor of 1.5 leaves line n unchanged

mars1129 [50]

Answer:

See Explanation

Step-by-step explanation:

This question requires further details. In absence of the details, I will answer on a general term.

When a line is dilated (whether expanded or compressed), the new line will be on the same line with the dilated line; however, the length of both lines will be different

Take for instance:

Line AB of coordinate (1,3) is horizontally dilated by 2,

Horizontal dilation rule is: y = f(cx) where c is the dilation factor

So, the new point will be

A'B' = (1, 3 * 2)

A'B' = (1,6)

When you compare the x coordinate of both line, you will observe that they have the same x coordinate of 1.

This implies that they are on the same level but different length

The same is applicable to vertical dilation

the new point will be:
