Answer:
a) R = 3.6
b) A = 2
Step-by-step explanation:
To find the value, start by modeling the inverse proportionality by using the base equations with the original givens.
y = k/x
12 = k/1.5
18 = k
Now we use that to model the equation
R = 18/A
And we can now use that to solve parts a) and b)
a)
R = 18/A
R = 18/5
R = 3.6
b)
R = 18/A
9 = 18/A
2 = A
Answer:
-2x - 10
Step-by-step explanation:
-2 x X = -2x
-2 x 5 = -10
Put them together to get:
-2x - 10
Answer:
68 feets of fencing
Step-by-step explanation:
Given that:
Area of square garden = 289 ft²
The side length of square garden can be obtained thus :
Area of a square = s²
Where s = side length
s² = 289
s = sqrt(289)
s = 17
Perimeter of square garden : 4s
Perimeter = 4* 17 = 68 feets
For this case, you must use the given expression, taking into account that:
n = number of days.
We have then that for day 21, n = 21.
Substituting we have:
a21 = 100 + (21-1) * 4
a21 = 180
Answer:
she sprints 180 yards on day 21
