The area of the actual square window = 2.25 m².
<h3>Scale Drawing</h3>
Scale drawing relates the actual length of an object to its length on a paper.
Given a scale of 1 in = 2 m, it means 1 in on paper is about 2 m of the actual length of the object.
Thus:
- Length on scale drawing = 0.75 in
- Actual length = x
Therefore:
1/2 = 0.75/x
x = 1.5 m
Area of the actual square window = 1.5² = 2.25 m².

The product of the greatest common divisor and the least common multiple of two numbers is always the product of the two numbers. So, you have
Answer:
A) s/3 +t
Step-by-step explanation:
To represent 1/3 of a number, we can simply divide this number by 3, meaning if s is the number, 1/3 of s would be s/3. Now to add t all we have to do is + t, making our answer s/3 + t
Whisper-20dB
Quiet Residence-30dB
Soft stereo in Residence-40dB
Average Speech-60dB
Cafeteria-80dB
Pneumatic Jackhammer-90dB
Loud crowd noise-100dB
Accelerating Bike-100dB
Rock concert-120dB
Jet Engine (75 ft away)-140dB
(1)Mode=100dB (since 100 is occurring the maximum no. of times, i.e. it has the highest frequency of 2)
(2)Mean=sum of observations/Total number of observations
=(20+30+40+60+80+90+100+100+120+140)/10
=770/10=10dB
(3)Median= 1/2[{n/2}th observation + {(n/2)+1}th observation], where, n=total no. of observations
So, 1/2[{10/2}th observation + {(10/2)+1}th observation]
=1/2[5th observation+6th observation]
=1/2[80+90] [Because:5th observation=80dB and 6th=90dB]
=1/2(170)
=85
Therefore, median=85dB
The answer is D. j - 14 = 28
Basically, saying the answer aloud, you will be saying the jellybeans my mom added to the bag minus the 14 jellybeans I had previously is equal to my total of 28 jellybeans I have now.
