(The equation I used: 25(5.45)=136.25.If you went any further you wouldn't of gotten the answer.)
Hope This Helps!
One possible equation would be 20 = 1/2x + 4.
Let x be the number of students in his homeroom. 1/2x is half of the students in his homeroom. Four more than 1/2 would be 1/2x + 4. This is, or equals, the 20 students that have tickets.
Answer:
z=20.8
x=16.97
y=12
Step-by-step explanation:
The triangle on the right is a 30,60,90 triangle, a special right triangle with simple rules to find the side lengths. sides A,B, and C where C is the hypotenuse (24 in your diagram). The short side A is= 1/2 of side C (12 in your diagram). The long side B is= side A*√3 (20.8 in your diagram).
The triangle on the left is another special right triangle called a 45,45,90. The rules for this triangle are C= A*√2, and B=A. Because of the rules in the 30,60,90 triangle, we know that side A is 12. This means that side B (y)=12. Side C (x)= 16.97.
Hope this helped! Sorry if my explanation is confusing, but the rules for special right triangles can be easily found online and then calculated :)
The grouping has changed in the equation.
3(mn) = (3m)n
This is the associative property of multiplication.
Answer:
82.5 feet.
Step-by-step explanation:
Let x represent number of days and y represent height of the plant.
We have been given that Jamie is measuring the growth of a bean plant in her garden. On the first day, the plant is 2.5 inches tall. Point (1,2.5) represent this situation.
On the fourth day, it is 14.5 inches tall. This information can be represented by point (4,14.5).
Let us find slope of the line using given points.
Now, we will point-slope form of equation to find the equation for the height of the plant.
Now, we will substitute in our equation.
Therefore, the height of Jamie’s plant will be 82.5 feet on the twenty-first day if it continues to grow.
