The distance around the park is the perimeter.
To find the perimeter add two lengths plus two widths:
Perimeter = 4.6 +4.6 + 2.7 +2.7 = 14.6 miles
Answer:
720 arrangements
Step-by-step explanation:
We have three spaces that we want to fill with any letter from "complexity":
__ __ __
For the first space, we have 10 letters to choose from (there are 10 letters in the word "complexity"). For the second space, since we have already used up one letter for the first space, we have 9 letters remaining to choose from. Similarly, we only have 8 letters remaining to choose from for the last space.
Now, we multiply them all together: 10 * 9 * 8 = 720 arrangements.
Note that we multiply instead of add. This is because for any letter we place in space 1, it can be paired with any of the 9 letters for space 2 and any of the 8 letters for space 3.
Hope this helps!
1) 2/3x , 2t , -1/3x
.
2) 2/3(3m^4 + 6) - (m^4 - m)
{ 3 and 3 get cancelled }
= 2m^4 + 6 - m^4 + m
= m^4 + 6 + m
.
Hope it helps! :)
Answer:
It is 7
Step-by-step explanation:
y = mx+b
y is the total cost.
x is the number of hours.
b : that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hours
