Answer:
To find the area of the rectangular sides, use the formula A = lw
To find the area of the triangular faces, use the formula A = 1/2bh,
Step-by-step explanation:
1st formula where A = area, l = length, and h = height.
2nd formula where A = area, b = base, and h = height.
Answer:
She needs to purchase 50 square feet of wood .
Step-by-step explanation:
we can find the number of square feet of wood needed to purchase by finding the area of the table
The area of the table = area of the triangle + area of the rectangle
Area of the triangle:
Area of the triangle = 
On substituting the values from the attached figure , we get
Area of the triangle = 
Area of the triangle = 
Area of the triangle = 10 square feet
Area of the rectangle:
Area of the rectangle = Length X Breadth
On substituting the values from the attached figure , we get
Area of the triangle = 
Area of the triangle = 40 square feet
Thus the area of the table = 10 + 40 = 50 square feet
Answer:
72.4 seconds
Step-by-step explanation:
We are given that,
Time taken by each person in the team = 18.1 seconds
Number of members in the team = 4
It is required to find the total time taken by the team to finish the race.
Thus, the time taken taken = 4 × 18.1 = 72.4 seconds
Hence. the team finished the race in 72.4 seconds.
Answer:
The correct option is C: I = 10⁸I₀.
Step-by-step explanation:
The function of the Richter scale is:

Since the magnitude of the earthquake is 8.0, the relation between the intensity, I, with the intensity of the threshold quake, Io, is:



Therefore, the correct option is C: I = 10⁸I₀.
