Answer:-1 over 2.
Step-by-step explanation:
Answer: 10 inches.
Step-by-step explanation:
We have to solve a system of equations.
The formula to calculate a triangle area is A = (b.h)/2
where b is the base and h is the height. This will be our first equation.
Since the height is 4 inches greater than the base, the second equation will be: h = b+4
We replace h and the value of the area (70 square inches) in the first equation, and we solve it by using the cuadratic equation formula:
70 = (b . (b+4)) / 2
70 . 2 = b² + 4b
140 = b² +4b
0 = b² + 4b - 140
The roots of this polynomial are -14 and 10. Since a distance can't be negative, the length of the base is 10 inches.
To get the x-intercept, we simply set y = 0 and solve for "x".
now, we have the slope and the y-intercept, well, let's plug those two in the slope-intercept form, reason why is called that anyway,
After converting 1350 cm into meters we get 13.5 m
Step-by-step explanation:
We need to convert 1350 cm into meters.
For converting cm into meters we need to divide the value of cm by 100
i.e 1/100 cm = 1 m
So, 1350/100 = 13.5 m
So, after converting 1350 cm into meters we get 13.5 m
