Answer:

80/140 = (80:20)/(140:20) = 4/7

4/7 = (4*4)/(7*4) = 16/28

4/7 = (4*5)/(7*5) = 20/35 not 20/28 not 20/32

4/7 = (4*5.5)/(7*5.5) = 22/38.5 not 22/37

The actual distance between parks is 24 miles On a map these parks are 8 inches apart How many miles are equal to one inch on th
vaieri [72.5K]

Each inch in the map is equivalent to 8 miles.

Explanation:

There is a distance of 24 miles between two parks. This 24 miles is represented by an 8-inch gap in the map.

So 8 inches on that particular map = 24 miles in real life.

To find the distance that an inch on the map represents we must divide both sides of the above equation. Since we need to calculate how much distance 1 inch represents we divide both the sides by 8 so that 8 inches on the map changes into 1 inch.

\frac{8}{8} inches on the map = \frac{24}{8} miles between the two parks in real life,

1 inch on that particular map = 3 miles in real life.

So each inch on the given map is equal to 8 miles in real life.

G(n) = 4n+5 f(n)= n^3+3n^2 find (g+f)(n)
Tpy6a [65]

Given:

The two functions are:

g(n)=4n+5

f(n)=n^3+3n^2

To find:

The function (f+g)(n).

Solution:

We have,

g(n)=4n+5

f(n)=n^3+3n^2

Now,

(f+g)(n)=f(n)+g(n)

(f+g)(n)=n^3+3n^2+4n+5

Therefore, the correct option is B.

Which is the sum of the first 6 terms of the geometric series?<br> 7+21 +63
Gwar [14]

Answer:

2,548

Step-by-step explanation:

First, we have to find out the rule. The rule is multiply the previous number by 3 to get the next number.

7x3=21

21x3=63

So, we would continue this pattern until we have the first 6 numbers which are 189, 567, and 1701.

The questions is asking for the SUM of the 6 numbers so you would add the those numbers and do this equation:

7+21+63+189+567+1701= 2548

Hope this helps! :)
