Answer: 13 sheets of paper
Step-by-step explanation:
We are given the dimensions of the box and the wrap paper:
Box:
Warp paper:
Now we need to find the surface area of the box and the area of the wrap paper:
Box:
Warp paper:
Dividing the area of the box by the area of the paper:
This means Angel's dad needs to purchase 13 sheets of wrapping paper.
Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
Answer:
I got B) ; 54m2
Step-by-step explanation:
the above diagram is a trapezium.
the area is gotten by; 1/2 (a+b)h
a = shortest side.
b = the longer side that is directly opposite to (a).
h = height.
1/2(3 + 9)9
1/2 by 12 by 9
to get 54
Answer:
m∠B > m∠C > m∠A
Step-by-step explanation:
The angle opposite the largest side in a triangle is the largest, and the angle opposite the shortest side is the smallest.
A study of 600 college students taking statistics 101 revealed that 54 students received the grade of
a. Typically 10% of the class gets an A
b. The difference between this group of students and the expected value is not significant at the 0.05 level. what does this mean in this case?
Your answer would mean that, =====> The probability of getting an A is 10% and only 9% got an A, in this study. The difference is less than 5% therefore, in this case, it is not significant.
Hope that helps!!!! : )
