Answer:
104.5 meters square
Step-by-step explanation:
The area of a trapezoid is found using the formula A = 1/2 (a + b)h. Substitute a = 8, b = 11 and h = 12.
The area is A = 1/2(8+11)*12.
A = 1/2 (19)*12 = 104.5
Answer:
412.5 miles
Step-by-step explanation:
1) 2.75/0.5=5.5
2)5.5x75=412.5
Using weighted average, it is found that she should score 67% on the computer science test.
- The weighted average is given by <u>each proportion multiplied by it's score</u>.
In this problem, the proportions and scores are given by:
- Proportion of 32% = 0.32 for a score of 300.
- Proportion of x for a score of 200.
- Proportion of 46% = 0.46 for a score of 300 + 200 = 500.
Then





She should score 67% on the computer science test.

2(x-5)=2x+3
2x-10=2x+3
2x=2x+13
0x=13
x=0
There are no solutions (13/0 is 0)
