Answer:

it can be used to determine the next high by simply dividing the previous number by 1.5

27/1.5=18 (1st to 2nd)

18/1.5=12 (2nd to 3rd)

12/1.5=8 (3rd to 4th)

Step-by-step explanation:

you need to find the similarity in them first check if they add or subtract the same numbers.

    -9      -6

27     18      12

so no. Which means it has to be a factor or a division.

27/1.5=18

18/1.5=12

12/1.5=8

and so it continue

horrorfan [7]

Answer:The number of words that she would still have to type to finish her essay is 1000

Step-by-step explanation:

Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be

4000/30 = 133.33 minutes.

If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be

45 × 30 = 1350 words

If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be

55 × 30 = 1650 words

Total number of words typed on Monday and Tuesday would be

1350 + 1650 = 3000 words

The number of words that she would still have to type to finish her essay would be

4000 - 3000 = 1000 words

Why are the solutions to the proportions 40/8 = x/10 and x/40 = 10/8 the same?
romanna [79]

Answer:

Both proportions are equivalent.

Step-by-step explanation:

We have been given two proportions \frac{40}{8}=\frac{x}{10} and \frac{x}{40}=\frac{10}{8}. We are asked to find why the solutions to our given proportions are equal.

We can solve proportions by cross multiplying them.

After cross multiplying our both proportions we will get same equation that is:

40*10=8*x

400=8x

8*x=40*10

8x=400

Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.

Given log Subscript 3 Baseline 2 almost-equals 0. 631 and log Subscript 3 Baseline 7 almost-equals 1. 771, what is log Subscript
kari74 [83]

You can use the properties of logarithm to get to the solution.

The approximate value for given term is given by

log_3(14) \approx 2.402

<h3>What is logarithm and some of its useful properties?</h3>

When you raise a number with an exponent, there comes a result.

Lets say you get

a^b = c

Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows

b = log_a(c)

Some properties of logarithm are:

log_a(b) = log_a(c) \implies b = c\\\\\log_a(b) + log_a(c) = log_a(b \times c)\\\\log_a(b) - log_a(c) = log_a(\frac{b}{c})

<h3>Using the above properties</h3>

log_3(2) + log_3(7) = log_3(2 \times 7) = log_3(14)\\\\0.631 + 1.771  = log_3(14)\\\\log_3(14) = 2.402

Thus,

The approximate value for given term is given by

log_3(14) \approx 2.402
