Answer:
triangle C has the largest area.
Step-by-step explanation:
From the the three triangles A, B, C based on the area occupied by the triangles, it can be seen that triangle C occupies the largest area.
On the centimetre grid, let each box represent one unit. For triangle A, the base is 2 boxes (i.e 2 units) and the height is 3 units, For triangle B, the base is 2 units and the height is 3 units while for triangle C, the base is 3 units and the height is 3 unit. The area of a triangle is given by:
Area = 
For triangle A:
Area =
= 
For triangle B:
Area =
= 
For triangle C:
Area =
= 
Therefore, triangle C has the largest area.
Answer:
y=1.5x+2.5
Step-by-step explanation:
First you find the slope:
or
lets change it into 1.5
Then write it in point-slope: (I used (1,4))
y-4=1.5(x-1)
y-4=1.5x-1.5
y=1.5x+2.5
Answer:
4.5%
Step-by-step explanation:
Find interest rate by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
I = $720, P = $2000 and t = 8 years, so
I = P*i*t
i = I/P*t
i = 720 / 2000 * 8
i = 0.045 = 4.5% per year
B: x
T: 3x
R: x + 8
x + 3x + (x+8) = 68
5x + 8 = 68
5x = 60
x = 12
B: 12
T: 36
R: 20
Answer:
they are in 225kilometers apart.
