For this case, we have that by definition, the proportions can be expressed in different ways. Example, if we have a dog and three cats:
75%: It's percentage
0.75: In decimal (75% are cats)
: In fraction. (There are of cats)
: Using ":" to separate sample values. (For every three cats there is a dog)
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
Example:
Answer:
Care should be taken with the proportions, always multiplying the numbers in the proportion by the same value.
Find c(8) in the sequence given by c(n) = 20 – 17(n − 1)
Answer:
the airline can offer 20 different flight paths under the given conditions.
Step-by-step explanation:
If the airline has 6 airports and the plane lands three times without staying in the same place twice, this is essentially a permutation problem. You want to find the number of ways to arrange 3 distinct airports out of 6.
This can be calculated using the formula for permutations of "n" items taken "r" at a time:
nPr = n! / (n - r)!
Where "n" is the total number of items (airports in this case) and "r" is the number of items to be arranged (3 landings in this case), and "!" denotes factorial.
So, in your case, the calculation would be:
6P3 = 6! / (6 - 3)!
= (6 * 5 * 4 * 3 * 2 * 1) / (3 * 2 * 1)
= 120 / 6
= 20
So, the airline can offer 20 different flight paths under the given conditions.

Step-by-step explanation:
It had wondering for days...
B: 600 yards
C: 14.86 yards
D: 29.71 yards
Answer:
The height is 14.86 yards ⇒ answer C
Step-by-step explanation:
* Lets explain how to solve the problem
- The flower garden in the shape of a trapezoid
- The shorter base to be 3 yards greater than the height
- The longer base to be 7 yards greater than the height
- The area must be 295 square yards
- The situation is modeled by the equation h² + 5h = 295
- We want to find the height that will give the desired area by using
the quadratic formula
- The quadratic formula is ,
where a is the coefficient of h² and b is the coefficient of h and c
is the numerical term
- The equation of the area is h² + 5h = 295
∵ h² + 5h = 295
- Subtract 295 from both sides
∴ h² + 5h - 295 = 0
- Lets find the values of a , b and c from the equation
∵ a = 1 , b = 5 , c = -295
∴
∴
∴
- OR
∴
- The dimensions of any figure must be positive value, then we will
neglect the negative value of h
∴ h = 14.86
* The height is 14.86 yards
Answer:
C: 14.86 yards
Step-by-step explanation:
to solve a quadratic equation we need to make it equal to zero and then use the Quadratic Formula
having
we have
a=1
b=5
c=-295
the answers for the formula are
h=14.85 and h=-17.36
as we are looking for a distance we can only take the positive answer, then
h=14.85
