Please find the least common denominator for 3/8 <br> 5/12
andriy [413]

Answer:

24

Step-by-step explanation:

Given two fractions \frac{3}{8} and \frac{5}{12}.

Factor the denominators of both fractions:

8=2\cdot 4=2\cdot 2\cdot 2\\ \\12=2\cdot 6=2\cdot 2\cdot 3

You can see that two digits 2 are the same in both denominators and there are two more factors: 2 in number 8 and 3 in number 12.

Thus, the least common denominator for  \frac{3}{8} and \frac{5}{12} is

2\cdot 2\cdot 2\cdot 3=24

Given that,

The speeds of an automobiles are given below:

20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58

We need to find the mean speed of the cars.

Mean = sum of observations/ no. of observation

M=\dfrac{20+35+42+52+65+49+24+37+23+41+50+58}{12}\\\\M=41.3

So, the mean speed of the cars is equal to 41.3 mph.

What’s the definition of input and output?
Vika [28.1K]

Input is the same as the x-term and output is the same as the y-term.

For example, take a look at the image provided with thee table.

Looking at the first box of our table, notice that if we subtract 5 from 1, we get -4 and if we subtract 5 from 2 we get -3 and if we subtract 5 from 3, we get -2.  Notice that in each case, we're subtracting 5 from the input to get the output.

I attached a table so you can practice if you'd like to. All you have to do is subtract 5 from each input and you will end up with the output. The first few are done for you. I also provided an answer key in the next image so you can check your work.

The last one might be a little trick. In the input, we have n which is a variable that represents any number. If we want to find the nth term, we simply subtract 5. So we have n - 5.

First image is practice if you'd like and the second is the key.

If you don't want to do it, no worries.

A $100,000 house appreciates at a rate of $3500 a year. a.Find the equation that models the value of the house in y dollars afte
MA_775_DIABLO [31]

Answer:

y = 100,000 + 3500x

$142,000

Step-by-step explanation:

a. The fixed cost is 100,000 while appreciation is 3, 500/year.

Now after x years, total appreciation equals 3,500 × x = 3500x

The total amount in dollars is thus :

y = 100,000 + 3500x.

b. The value of the house in 12 years.

Since y = 100,000 + 3500x, here, y = ? and x = 12.

y = 100,000 + 3500(12) = 100,000 + 42,000 = $142,000
