Answer:
Any possible observation and perhaps a research project could show if a given hypothesis seems to be inaccurate.
Step-by-step explanation:
The prediction seems to be the hypothesis because it requires anything other than an assumption. The theory almost all of the moment begins with the problem which would then be discussed throughout context analysis. Only then do investigators or scientists begin to establish observable well as testable theory.I

While on vacation, you rent a bicycle. You pay $9 for each hour you use it. It costs $5 to rent a helmet while you use the bicycle.
Answer:
[tex]Rental\ Cost = 9 n + 5[/tex]
Step-by-step explanation:
Question is incomplete; See Attachment
Required
Complete the table
To complete the table, we simply substitute n for 1,2 or 3
So: The rental cost, when the hours is n is as follows;
[tex]Rental\ Cost = 9 * n + 5[/tex]
[tex]Rental\ Cost = 9 n + 5[/tex]

X-5(x-1)=x-(2x-3) what does it equal
Answer:
[tex]x = \frac{2}{3} [/tex]
Step-by-step explanation:
[tex]x - 5(x - 1) = x - (2x - 3) \\ x - 5x + 5 = x - 2x + 3 \\ x - 5x + 2x - x= 3 - 5 \\ - 3x = - 2[/tex]
Divide both sides of the equation by -3
[tex] \frac{ - 3x}{ - 3} = \frac{ - 2}{ - 3} \\ x = \frac{2}{3} [/tex]

Step-by-step explanation:
hav a great day
Answer:
1085/3 = 361.7
Step-by-step explanation:
Expand −8.68/0.024 ≈361.666666667 by multiplying both numerator and the denominator by 1000.
8680/-24 ≈361.666666667
Reduce the fraction −8680/24≈361.666666667 to lowest terms by extracting and canceling out −8.
1085/3≈361.7
What is the maximum number of rectangular blocks measuring 2 by 3 by 4 that can
fit into a box measuring 12 by 21 by 40?
Volume of small box :
[tex]v=l\times b\times h\\\\v=2\times 3\times 4\\\\v=24\ units^3[/tex]
Volume of big box :
[tex]V=L\times B\times H\\\\V=12\times 21\times 40\\\\V=10080\ units^3[/tex]
Number of small boxes that can fit into bigger box :
[tex]n=\dfrac{V}{v}\\\\n=\dfrac{10080}{24}\\\\n=420[/tex]
Therefore , 420 such boxes can fit .
Hence , this is the required solution .
Your temperature is 99 degrees during first period. By 7th period,your temperature is 102 degrees. How many degrees did your temperature change? Should you be at school.?
Given :
Temperature at first period , [tex]T_1=99^oF[/tex] .
Temperature at seventh period , [tex]T_7=102^oF[/tex] .
To Find :
The change in temperature .
Solution :
We know , change in temperature is given by the difference between final and initial temperature .
[tex]\Delta T=T_7-T_1\\\\\Delta=(102-99)^oF\\\\\Delta=3^oF[/tex]
So ,the change in temperature is [tex]3^oF[/tex] .
Now , the average body temperature of human body is [tex]98.6^oF[/tex] and [tex]100.4^oF[/tex] is considered a fever .
Therefore , we should not be in school and take rest .
Hence , this is the required solution .

Solve for n 19 + 10n = 7n - 20
Answer:
n = -13
Step-by-step explanation:
19 + 10n = 7n - 20
Subtract 7n from each side
19 + 10n-7n = 7n-7n - 20
19+3n = -20
Subtract 19 from each side
19+3n -19 = -20-19
3n = -39
Divide each side by 3
3n/3 = -39/3
n = -13
160+3x=195-2x what is the answer
Answer:
x = 7
Step-by-step explanation:
160+3x=195-2x
Add 2x to each side
160+3x+2x=195-2x+2x
160 +5x = 195
Subtract 160 from each side
160+5x-160 = 195-160
5x = 35
Divide by 5
5x/5 = 35/5
x = 7

If you and a friend each toss two pennies at the same time, what is the probability that all four pennies will be tails?
A. 1/2
B. 1/4
C. 1/8
D. 1/16
E. 1/32
Answer:
1/16
Step-by-step explanation:
Probability helps us to know the chances of an event occurring. The probability that all four pennies will be tails is (1/16).
What is Probability?Probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of a penny getting a tail is 0.5 or (1/2), therefore, the probability of four penny getting a tail can be written as,
[tex]\rm Probability = \dfrac14 \times \dfrac14 \times \dfrac14 \times \dfrac14 = \dfrac1{16}[/tex]
Hence, the probability that all four pennies will be tails is (1/16).

Micheal is 5 years older than Rui Feng and Vishal is thrice as old as Micheal if Rui Feng is p years old, find i) Michael's present age, ii) Vishal's present age, ii) the sum of there age in 6 age years time, iv) the sum of their ages 3 years ago.
Answer:
Michael's present age = p + 5
Michael's present age = 3p + 15
Sum of there ages 6 year age = 5p + 38
Sum of there ages 3 year ago = 5p - 11
Step-by-step explanation:
Assume;
Age of Rui Feng = x
Age of Micheal = x + 5
Age if Vishal = 3[x+5]
Given:
Age of Rui Feng = P
Computation:
Michael's present age = Age of Rui Feng + 5
Michael's present age = p + 5
Vishal's present age = 3[p + 5]
Michael's present age = 3p + 15
Sum of there ages 6 year age = [p + 6] + [p + 5 + 6] + 3[p + 5] + 6
Sum of there ages 6 year age = 5p + 38
Sum of there ages 3 year ago = [p - 3] + [p + 5 - 3] + 3[p + 5] - 3
Sum of there ages 3 year ago = 5p - 11
Which table has a constant of proportionality between y and x of 8/5
Answer:
Table 1
Step-by-step explanation:
Constant of proportionality is simply the ratio of y to x. In each of the given tables, the second column is y and the first is x.
Table 1:
4 32/5
10 16
11 88/5
Let's find the constant of proportionality for each row:
R1: (32/5) / 4 = 8/5
R2: 16/10 = 8/5
R3: (88/5) / 11 = 8/5
Thus, since this matches the requirements and all three rows have the same constant, Table 1 is the answer.
If you check the other two tables in the same way, you'll see that neither has a constant of proportionality of 8/5.
Hope this helps!
