C.) Are the same length
<u>How you know-</u>
No matter how long the rectangle is the diagonals always will measure the same length. Think about two sides of a square, they have to equal the same length because if they were not the same then the shape wouldn't be a square.
Answer:
50 students
Step-by-step explanation:
20 + 30 = 50
Answer:
see attached diagram
Step-by-step explanation:
First, draw the dashed line 50x+150y=1500 (dashed because the inequality is without notion "or equal to"). You can do it finding x and y intercepts.
When x=0, then 150y=1500, y=10.
When y=0, then 50x=1500, x=30.
Connect points (0,10) and (30,0) to get needed dashed line.
Then determine which region (semiplane) you have to choose. Note that origin's coordinates (0,0) do not satisfy the inequality 50x + 150y>1500, because
![50\cdot 0+150\cdot 0=0](https://tex.z-dn.net/?f=50%5Ccdot%200%2B150%5Ccdot%200%3D0%3C1500.)
This means that origin lies outside the needed region, so you have to choose the semiplane that do not contain origin (see attached diagram).
The first step in this equation is to Subtract 18 from both sides of the equation.
