Answer:
18%
Step-by-step explanation:
Iliana's math grade increased from 65 to 86.
So, the percentage increase in the her math grade will be 
% (Approximate)
Now, Fiona's math grade increased from 70 to 80.
Hence, the percentage increase in her math grade will be 
% (Approximate)
So, the difference rounded to the nearest whole number between the approximate percent increases in math grades will be
(32.31 - 14.28) ≈ 18%
So, it is eighteen percent. (Answer)
To solve this problem you must apply the proccedure shown below:
1. You have that the lenght ot the board is 6 feet and <span> forms a 60 degree angle with the ground. Therefore, you have:
Sin</span>α=opposite/hypotenuse
α=60°
opposite=x
hypotenuse=6
2. When you substitute the values, you obtain:
Sin(60°)=x/6
3. Now, you must solve for x, as following:
x=6Sin(60°)
x=5.19
Therefore, the answer is: 5.19 feet.
The number 2*2*2*4*5 is not in its prime factorization because not all the factors are prime numbers. A prime number is a number that has no other factors except for 1 and itself.
4 is not a prime number, since it can be divided by 2. The number can be broken down into its prime factors by dividing by 2, and it becomes 2*2.
Therefore, the factorization of the number 2*2*2*4*5 can be broken down to 2*2*2*2*2*5.
Answer:
Step-by-step explanation:
we know that
---> by addition angle postulate
we have
----> given problem
----> given problem
substitute in the expression above
Divide by 2 both sides
2x + 4
To model 2x+4, you need :
2 positive x-tiles to represent 2x.
4 positive unit tiles to represent 4.
3x+(-1)
To model 3x+(-1), you need :
3 positive x-tiles to represent 3x.
1 negative unit tile to represent (-1).
