Answer:
30 inches squared
Step-by-step explanation:
First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.
Answer:
a. 114 minutes
b. 48 minutes
Step-by-step explanation:
Given that
Time spent over the piano is 75 minutes
a. if Priya practice violin for 152% as Han Practiced for piano
So the minutes she practice in Violin is
= 75 minutes × 152%
= 114 minutes
Likewise
b. If Tyler practiced for clarinet for 64% as Han Practiced for piano
So the minutes he practice in Clarinet is
= 75 minutes × 64%
= 48 minutes
The same is to be considered
For question number 1:The plot H = H(t) is the parabola and it reaches its maximum in the moment when exactly at midpoint between the roots t = 0 and t = 23. At that moment t = 23/2 or 11.5 seconds.
For question number 2:To find the maximal height, just simply substitute t = 11.5 into the quadratic equation. The answer would be 22.9.
For question number 3:H(t) = 0, or, which is the same as -16t^2 + 368t = 0.Factor the left side to get -16*t*(t - 23) = 0.t = 0, relates to the very start of the process, when the ash started its way up.The other root is t = 23 seconds, and it is precisely the time moment when the bit of ash will go back to the ground.
