Answer:
50%
Step-by-step explanation:
The equation for circumference is:
[tex]C=2\pi r[/tex]
In this case, the radius and the circumference are directly proportional meaning that if the radius increases by 50%, the circumference will also increase by 50%.
Let's use some examples to prove this:
Radius : 2
Increase by 50% : 2*50%=2*(50/100)=2(1/2)=1 --> 1+2 = 3
[tex]C=2\pi r=2\pi 3=6\rightarrow 50 \ percent\ increase\ from\ 4\\C=2\pi r=2\pi 2=4[/tex]
Radius : 4
Increase by 50% : 4*50%=4*(50/100)=4(1/2)=2 --> 2+4 = 6
[tex]C=2\pi r=2\pi 6=12\pi\rightarrow50\ percent\ increase\ from\ 8\\C=2\pi r=2\pi 4=8\pi[/tex]
In both cases, when we increased the radius by 50%, the circumference also increased by 50%, proving our previous statement correct.
Therefore, when the radius of a circle is increased by 50%, the circumference will also increase by 50%
What is equivalent to 4x -8? a: 2 (2x - 6) b: 2 (2x - 4) c: x - 8 + 3x
Answer:
The answer is b) 2(2x-4) and c)
Step-by-step explanation:
Okay lets try a) 2(2x-6)
2 x 2x - 2 x 6= 4x-12
b) 2(2x-4)
2 x 2x - 2 x 4=4x-8
c) : x-8+3x

Answer:
1/2b - 5 (the third one)
Step-by-step explanation:
"Denni is five years less..."
this tells us we will need to be subtracting five, which knocks out the other answers.
"..one-half his brothers age."
since b represents the age of his brother, one half his brothers age is 1/2b
That leaves us with 1/2b - 5

Answer:
Missing denominator = 36
Step-by-step explanation:
Let us assume that,
→ Missing denominator = x
Now we have to,
→ Find the required value of x.
Forming the equation,
→ 27/x = 3/4
Then the value of x will be,
→ 27/x = 3/4
→ 27 × 4 = 3 × x
→ 108 = 3x
→ 3x = 108
→ x = 108/3
→ [ x = 36 ]
Hence, the value of x is 36.
linear equation in point slope form for a line that passes through the point (3,2) and has a slope of -4
Answer:
(c) y-2 = -4(x-3)
Step-by-step explanation:
The point-slope equation of a line is ...
y -k = m(x -h) . . . . . . line through point (h, k) with slope m
For (h, k) = (3, 2), and m = -4, the equation of the line is ...
y -2 = -4(x -3)

the temperature in Austria one morning is -5 degrees Celsius at 8:00 and increased by 2 degrees Celsius every hour until 12:00. wht will the temperature be
at 11:30
The equation illustrates that the temperature by 11:30 am will be 2 degree Celcius.
How to solve the equationIt should be noted that there are 3 hours and 30 minutes from 8 am to 11.30 am.
Therefore, the temperature by 11:30 will be:
= -5 + 2(3.5)
= -5 + 7
= 2°
In conclusion, the correct option is 2°.

Answer:
27. x=7/20; 28. m= 3.7; 29. a= 5.8
30. x= 6; 31.x= 46
Step-by-step explanation:
27.
[tex]x + \frac{2}{3} = \frac{9}{ 10} [/tex]
you are going to carry the 2/3 over the equal sign. This will make the 2/3 negative so...
[tex]x = \frac{9}{10} - \frac{2}{3} [/tex]
now calculate it by finding the LCM of 10 and 3 ....this will be 30....you can just multiply the 10 and 3
now
30 into 10 goes 3 times....you will multiply this 3 with the 9 to get 27
30 into 3 goes 10 times...you will multiply this 10 with the 2 to get 20
[tex]x = \frac{27 - 20}{30}[/tex]
[tex]x = \frac{7}{30} [/tex]
Hopefully you understand
28.
[tex]1.2 = m - 2.5[/tex]
[tex]1.2 + 2.5 = m[/tex]
carry the 2.5 over the equal sign to get the m by itself...this is because you are trying to find m
when the negative number goes over the equal sign it will become positive...this is why you add it to the 1.2
m= 3.7
you can do the other on your own
the error in 30 is that the 7 should not be added to the 13 but subtracted
..this is because when you carry the positive number over the equal sign it will become negative..hence you subtract it
[tex]x + 7 = 13[/tex]
[tex]x = 13 - 7[/tex]
[tex]x = 6[/tex]
and for 31...the 12 should not be subtracted but added since when it goes over the equal sign it will become positive.
[tex]34= y - 12[/tex]
[tex]34 + 12 = y[/tex]
[tex]y = 46[/tex]

The Statue of Liberty is approximately 300 feet high, including the base upon
which the statue stands. If the base is 150 feet high, what percent of the total
height is the statue itself?
Answer:
The state itself is 50% of the total height.
Explanation:
Well, if the height including the base is 300 ft, that'd mean the total height of the statue itself is (300-150) ft = 150 ft.
Thus, it is (150/300)*100% = 50% of the total height.

Select the outlier in the data set.
then
If the outlier were removed from the data set, would the mean increase or decrease?
====================================================
Explanation:
The set of given numbers sorts to this
11, 50, 72, 78, 80, 81, 85, 89, 94, 96, 97, 98
The majority or main cluster of the values are between 50 and 98. The outlier 11 is off on its own pretty far from the main cluster.
Let's find the mean of every value in this set. If you added up all the numbers, then you should get 931. Divide this over the number of values (12) and the mean of this set is roughly 931/12 = 77.5833
Now let's kick out the outlier 11. The 931 will drop to 931-11 = 920. Divide that new smaller sum over the 12-1 = 11 items left to get 920/11 = 83.6364 approximately.
--------------
To summarize so far:
old mean = 77.5833 approximatelynew mean (removed outlier) = 83.6364 approximatelyWe see that the mean has increased. This is because the outlier was pulling down on the mean to make it smaller than it should be. Once the outlier is out of the picture, the new mean will increase and better represent the center of the main cluster.
