Answer:
Zack will need 17 1/2 ft of fence
Step-by-step explanation:
To calculate this we will first pass the numbers to complete fractions
5 1/4 ft = 21/4 ft
3 1/2 ft = 7/2 ft
We have to add 2 times each side
21/4 ft + 21/4 ft + 7/2 ft + 7/2 ft =
Now we have to pass all the fractions to the same denominator
21/4 ft + 21/4 ft + 14/4 ft + 14/4 ft =
70/4 = 17 1/2

Answer:
-938 ft
Step-by-step explanation:
the bird will be going down in elevation. the distance between -422 and -1360
-1360+422= -938
Answer:

Step-by-step explanation:
We are asked to find the length of a segment or the <em>distance</em> between the 2 points. The formula for distance is:

where (x₁ y₁) and (x₂, y₂) are the points. We are given the points ( -5, 4) and (6, -3). If we match the number and the corresponding variable, it is:
- x₁= -5
- y₁= 4
- x₂= 6
- y₂ = -3
Substitute the values into the formula.

Solve inside the parentheses.
- 6--5 (Back to back negative signs become a positive)= 6+5 =11
- -3-4= -7

Solve the exponents.
- (11)²= 11*11= 121
- (-7)²= -7*-7= 49

Add.


Even though it's not specified, we could round to the nearest hundredth to make the answer more concise. The 8 in the thousandth place tells us to round the 3 to a 4 in the hundredth place.

The length of the segment is <u>√170</u> or approximately <u>13.04. </u>
0 represents ground level...the surface of the ground...and anything below it will be negative, just like everything above it will be positive
