Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
Answer:
d) 63 square units
Step-by-step explanation:
x = 3 units (base - b)
y = 6 units (width - w)
h = 7 units (length and height - l and h)
- Area of a rectangle: l*w
- Area of a triangle: 1/2*b*h
For the triangles:
Area of a triangle: 1/2*b*h
A = 1/2 * 3 * 7
A = 1/2 * 21
A = 10.5
*Since there are two triangles, it would be 10.5 * 2 = 21
For the rectangle:
Area of a rectangle: l*w
A = 7 * 6
A = 42
Now, we add them together:
A = 42 + 21
A = 63 square units
Therefore, the area of the parallelogram is 63 square units
Hope this helps!
Divide 7.5 by 12 which equals 0.625
The answer should be less than 1 bag.
