Hello,
Here is the formula to find the area of the trapezoid:
A=1/2(b1+b2)×h
Where b1 represent big base
b2 represent small base
and h represent height
Now, we just need to replace the number to get the final answer:
A=1/2(16.8+6.9)×2
A=1/2(23.7)×2
A=23.7 square yards. As a result, the area of the trapezoid is 23.7 square yards. Hope it help!
Answer: 22 attendees can attend the corporate team-building event, with a budget of $46.
1. 8 = 4x
2. 8/4 = 4x/4
3. x = 2, each ticket would cost $2 per attendee
4. $46/$2 = 23
If one equation is the same, there is a multiply factor:
f*(3x+2y)=f*(-12)
You need to find the same factor for both members.
3x-2y=12. This is not the same.
-3x-2y=12. This is the same. The factor is (-1)
15x+10y=-60. This is the same. The factor is 5.
6x+2y=-12. This is not the same.
6x+4y=-24. This is not the same.
1.5x+y=-6. This is the same. The factor is 1/2.
x+ 2/3y=-12. This is not the same.
Good luck!

Answer:
The teacher can make 7 groups of 6 students
Step-by-step explanation:
24+18= 42. The biggest number you can use to divide and get a real number is 7.
Target concentration = 20%.
Ratio of 12% and 30% alcohols needed
30-20 : 20-12 = 10:8 = 5:4
Volume of 12% = 72 mL * (5/(5+4)) = 40 mL
Volume of 30% = 72 mL *(4/(5+4)) = 32 mL
Total = 40+32 = 72 mL of 20%
