Answer:
Uhm so I did 4×4=16 than 4×32=128 than 4×42=168
You add 16+128=144 than you divide 144÷168 which gives you a decimaled number which I got 0.8 if you round up its 1.0

What is the area of the polygon?
Answer: [tex]810m^{2}[/tex]
Step-by-step explanation:
First, we divide the composite figure into two distinct geometric shapes. This would be a triangle and a square. To find the triangle we use the formula:
A = 1/2bh
To find the base of the triangle we can add:
9 + 9 + 18 = 36
Now we plug in and solve:
A = 1/2bh
A = 1/2(36)(27)
= 1/2(972)
= 486
To find the square, we can use length x width:
18×18 = 324
Now, we add the sums together:
486 + 324 = 810

Shannon scored 36 point on 6 questions on her test. what is the unit rate for one question?
Answer:
6 poinnts per question
Step-by-step explanation:
Answer:
x = the number of points for each question
6 = number of questions
36 = total number of points
number of questions times the number of points will equal total points
6x = 36
divide both sides by 6
6x/6 = 36/6
x= 6

Ms. Roberts studied her students' geography test scores and sleeping habits. She found that students who slept less tended to earn
lower scores on the test. What conclusion should she make?
Step-by-step explanation:
she should tell the students that sleep less to get to their beds early, as the brain needs rest to function properly
Answer:
There is a correlation between test score and amount of sleep. There may or may not be causation. Further studies would have to be done to determine this.

Answer:
∠ QST = 68°
Step-by-step explanation:
∠ QST + ∠ RSQ = ∠ RST , that is
∠ QST + 64° = 132° ( subtract 64° from both sides )
∠ QST = 68°
In ΔOPQ, q = 110 inches, o = 970 inches and ∠P=167°. Find the area of ΔOPQ, to the nearest square inch.
Answer:
[tex]Area = 12004[/tex] square inches
Step-by-step explanation:
Given
[tex]q = 110[/tex]
[tex]o = 970[/tex]
[tex]\angle P =167[/tex]
Required
The area of the triangle
To do this, we use:
[tex]Area = \frac{1}{2} * o * q * sin(P)[/tex]
So, we have:
[tex]Area = \frac{1}{2} * 970 * 110 * sin(167^\circ)[/tex]
[tex]Area = \frac{1}{2} * 970 * 110 * 0.2250[/tex]
[tex]Area = 12003.75[/tex]
Approximate
[tex]Area = 12004[/tex]

Use the formula L= 10 log 10 R, where Is the loudness of a sound and R is the sound's relative intensity. to find out how much louder 20 people talking would be than one person talking. Suppose the sound of one person talking has a relative intensity of 80 decibels.
Answer:
[tex]X=24.1decibels[/tex]
Step-by-step explanation:
From the question we are told that:
Loudness function [tex]L= 10 log_{10} R[/tex]
Sound of a person [tex]S_p=80\ decibels\ or 10^8[/tex]
Number of persons talking [tex]n=20 people[/tex]
Generally the Relative intensity for 20 people is mathematically given by
Relative intensity for[tex]R_{20}=[/tex][tex]20*10^8[/tex]
Relative intensity for[tex]R_{20}=[/tex][tex]20^8[/tex]
Generally the loudness for 20 people is mathematically given by
[tex]L_{20}= 10 log_{10} R[/tex]
[tex]L_{20}= 10 log_{10} 20^8[/tex]
[tex]L_{20}= 10 (8 log_{10} 20)[/tex]
[tex]L_{20}= 104.1 decibels[/tex]
Therefore increase in loudness X is given as
[tex]X=104.1-80=-52.90[/tex]
[tex]X=24.1decibels[/tex]
