2 answers:
Answer:
Answer is option B) 2
Step-by-step explanation:
A parking garage opens at 8 am. The given graph shows number of cars at y axis and time at x axis.
Now we have to find the slope of the line shown in the graph.
This line passes through two points (0, 60) and (10, 80)
Slope of a line is represented by
Now we put the values in the formula
m = 2
Therefore, answer is option B) 2

- Option B
Step-by-step explanation:
Given is the hexagonal pyramid.
We know the radius of the base is same as its side.
<u>Find the base area:</u>
- A = 3√3/2a²
- A = 3√3/2*6² = 54√3
<u>Given the height and radius, find the side of the lateral triangular faces:</u>
Each of 6 triangles have sides 10, 10 and 6 units.
<u>Find the area using heron's formula:</u>
- s = P/2 = (10*2 + 6)/2 = 13
- s - a = s - b = 13 - 10 = 3
- s - c = 13 - 6 = 7
<u>Total surface area:</u>
Correct choice is B
Answer:
Width = 4.8 inches
Step-by-step explanation:
The perimeter of a rectangle is given by the formula:
Where
P is perimeter
l is length
w is width
Given length = 3.6 and perimeter = 16.8, we plug them in into the formula and figure out the width, w. Process shown below:
Hence, the width is 4.8 inches
