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.
Answer:
Hello, the answer is 0.5
Step-by-step explanation:
44 ÷ 22 = 2
2 ÷ 2 = 1
1 ÷ 2 = 0.5
Hope this helps :)
Answer:
1/6 or one sixth
Step-by-step explanation:
So, to be a linear relationship....the difference between the two consecutive "x" values and the difference between the two consecutive "y" values must be same.
In this case,
if we look at the x values , 4 - 3 = 1
3 - 2 = 1
2 - 1 = 1
they are all the same,
<u>BUT,</u><u><em /></u> if we look at the y values, 11.5 - 8.5 = 3
8.5 - 6.5 = 2
6.5 - 4.5 = 2
Here, the differences between the "y" values are all not the same.
<em><u>SO, the relationship is not linear.</u></em>
