Answer:
She needs 50 ft² of wood to cover the table
Step-by-step explanation:
You need to know the formula for area of a trapezoid, which is
A = (B1 + B2)h/s (add the bases together, multiply by the height, then divide
by 2)
We are given B1 = 12, B2 = 8, and h = 5, so plug them in and simplify
A = (12 + 8)(5)/2
A = (20)(5)/2
A = 100/2
A = 50 ft²
Answer:
Option D.
Step-by-step explanation:
Consider option D. ![y\leq \frac{3x}{4}+10\,,\,y\leq \frac{-x}{2}-3](https://tex.z-dn.net/?f=y%5Cleq%20%5Cfrac%7B3x%7D%7B4%7D%2B10%5C%2C%2C%5C%2Cy%5Cleq%20%5Cfrac%7B-x%7D%7B2%7D-3)
Take point (0,0)
On putting this point in inequation
, we get
which is true . So, solution is region towards the origin i,e region below the line
including the line itself .
On putting (0,0) in inequation
, we get
which is false , so solution is region away from the origin i.e region below line
including the line itself .
So, common solution to both the inequations is the shaded part in the given figure .
In other words, we can say that the graph shown in the given figure represents system of equations: ![y\leq \frac{3x}{4}+10\,,\,y\leq \frac{-x}{2}-3](https://tex.z-dn.net/?f=y%5Cleq%20%5Cfrac%7B3x%7D%7B4%7D%2B10%5C%2C%2C%5C%2Cy%5Cleq%20%5Cfrac%7B-x%7D%7B2%7D-3)
