The art class is planning to paint a mural on the outside wall this figure is a scale drawing of the wall the scale is 2 inches:
3 feet the scale drawing is 28 inches by 11 inches
1 answer:
Answer:
The area of the actual wall is 693 square feet.
Step-by-step explanation:
Step 1 : Finding the length of the wall in feet.
Length of the wall in the scale drawing = 28 inches
Length of the actual wall = feet
Length of the actual wall = feet
Length of the actual wall = 42 feet
Step 2 : Finding the width of the wall in feet.
Width of the wall in the scale drawing = 11 inches
Width of the actual wall = feet
Width of the actual wall = feet
Width of the actual wall = 16.5 feet
Step 3 :
Find area of the wall in square feet.
Area of the actual wall = Length x Width
Area of the actual wall = 42 x 16.5
Area of the actual wall = 693 square feet.

The average velocity of the object after during the first three seconds is: 48m/s
The time at which the instantaneous velocity equals the average velocity within the first three seconds is 1.5 seconds.
<h3>What is instantaneous and average velocities?</h3>Instantaneous velocity is the speed of an object at a particular point in time.
Average velocity is the velocity of an object after covering a certain distance for a period of time
Analysis:
Given
initial height = 600 feet
Height with respect to time = f(t) = -16 + 600
a) Height at t = 0 = 600 feet
Height at t = 3 seconds = f(3) = -16 + 600 = 456 feet
Distance travelled = 600 - 456 = 144 feet
Average velocity = distance travelled/time taken = 144/3 = 48 feet/seconds
b) instantaneous velocity at time t = =
= -32t
when instantaneous velocity equal average velocity
-32t = -48
t = 1.5 seconds
In conclusion, the Average velocity after 3 seconds is 48 feet per seconds and the time taken for the average velocity to equal the instantaneous velocity is 1.5 seconds.
