Evaluate without any decimals or rounding in any way. [tex]8\sqrt{6}[/tex]
Answer:
[tex] \sqrt{ 384} [/tex]
Step-by-step explanation:
Well I commented this already but I'm not sure if you saw it. If you're trying to convert it all to a radical form then you square the 8 and multiply it by the 6.
[tex]8 \sqrt{6} [/tex]
8² = 64
64 • 6 = 384
[tex] \sqrt{ 384} [/tex]

Which of the following is the correct value for x?
Answer: 56
Step-by-step explanation:
Answer:
x = 55.94 degrees
Step-by-step explanation:
(to find x, use cosine) (cos = [tex]\frac{adjacent}{hypothenuse}[/tex])
First step: write out the equation
⇒ cos x = [tex]\frac{14}{25}[/tex]
Second step: find out what [tex]\frac{14}{25}[/tex] is
⇒ [tex]\frac{14}{25}[/tex] = 0.56
Third step: find out what the cos-1 of 0.56 is
⇒ cos-1 of 0.56 = 55.94
Fourth step: you got your answer
⇒ x = 55.94
please help asap What is the sum of the following two polynomials?
(3x2 – 5x + 3) and (-x2 – 3x)
Answer:
2x² - 8x + 3
Step-by-step explanation:
( 3x² - 5x +3) + (-x² - 3x)
= 3x² - 5x +3 - x² - 3x
= 3x² - x² - 5x - 3x + 3
= 2x² - 8x + 3

A pair of shoes cost $88. You get
a 20% discount and pay 8% tax.
What is the final price of the
shoes?
Answer:
$77.44
Step-by-step explanation:
If the shoes cost $88 but you get a 20% discount, subtract 20% from 88: -->
$88-20% = $70.4
Then add 8% of 88 to 70.4 -->
8% of $88 = $7.04.
$70.4 + $7.04 = $77.44
Therefore the final price of the shoes are $77.44

BC = 9
EF = 27
27 ÷ 9 = 3
Ratio similarity scale is, 1 : 3
We have AB ~ DE
AB = x
DE = 24
24 ÷ x = 3
24 ÷ 3 = x

The value of x is 8
2⁄7 · n = 4 what is the answer
Answer: the answer is 14 if the 2 and 7 are a fraction and if it’s just 27xn=4 the answer is 4/27 and in decimal form it’s 0.148
Step-by-step explanation:
Answer: n=14
First, multiply 2/7xn which is 2n/7=4
Next, multiply both sides by 7 to get the 2n on one side by its self (2n=28)
Then divide 28 by 2 which gives you n=14

144 coins are divided equally among some children. If there were 3 children fewer, each child would have 16 coins. How many children are there?
Answer:
12
Step-by-step explanation:
144/16=9
Each child gets sixteen coins if there are nine children.
9+3=12
There are three more children so there are twelve.
Write an equation in slop intercept form (y=mx+b) for the line that has a slope (m) of 12 and passes though the point (3,20)
Answer:
y=12x-4
Step-by-step explanation:
To find the slope intercept form, we know the m(slope) but we need to find b.
y and x is given to us, so we can find b.
Plug in the numbers provided into the slope intercept form.
y=mx+b
20=(12)(2)+b
20=24+b
To find b, we have to get b by itself. So, we subtract both sides by 24.
-4=b
Now that we found b, we can plug this into the equation.
y=12x-4
Which equation can be used to solve for the value of x in the diagram?

The average high temperature during the hottest month in Beijing, China, is 72°F. The average high temperature during the coldest month in Beijing is 18°F. The function t = 27 cosine (StartFraction pi Over 6 EndFraction (m minus 6)) + 45, where m represents the number of months after January, models the temperature throughout the year in Beijing. During which month in the year would the temperature reach 55°F? August September November December
Answer:
During the month of September.
Step-by-step explanation:
The temperature in Beijing, in m months after January, is given by the following equation:
[tex]T(m) = 27\cos{(\frac{\pi}{6}(m-6))} + 45[/tex]
In which m is the number of months after January.
During which month in the year would the temperature reach 55°F?
We have to find m for which: T(m) = 55. So
[tex]T(m) = 27\cos{(\frac{\pi}{6}(m-6))} + 45[/tex]
[tex]55 = 27\cos{(\frac{\pi}{6}(m-6))} + 45[/tex]
[tex]27\cos{(\frac{\pi}{6}(m-6))} = 10[/tex]
[tex]\cos{(\frac{\pi}{6}(m-6))} = \frac{10}{27}[/tex]
Applying the inverse cosine to both sides:
[tex]\cos^{-1}{(\cos{(\frac{\pi}{6}(m-6))})} = \cos^{-1}{(\frac{10}{27})}[/tex]
[tex]\frac{\pi}{6}(m-6) = 1.19[/tex]
[tex]\pi(m-6) = 6*1.19[/tex]
[tex]\pi m - 6\pi = 6*1.19[/tex]
[tex]\pi m = 6*1.19 + 6\pi[/tex]
[tex]m = \frac{6*1.19 + 6\pi}{\pi}[/tex]
[tex]m = 8.27[/tex]
8.27 months after January
8.27 + 1 = 9.27, so during the month of September.

B. September

Identify the outlier in the data set, and determine how the outlier affects the mean, median, and mode of the data. Then tell which measure of central tendency best describes the data with and without the outlier. Justify your answer. 85, 91, 83, 78, 79, 64, 81, 97
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
85, 91, 83, 78, 79, 64, 81, 97
Ordered data : 78, 79, 81, 83, 85, 91, 97
Mean:
Σx / n =
n = sample size = 8
(64+78+79+81+83+85+91+97) / 8
= 658 / 8
= 82.25
Median = 1/2(n+1)th term
1/2(8+1)th term = 1/2 * 9 = 4.5th term
(4th term + 5th term) /2 = (81 + 83) / 2 = 82
Mode = 85, 91, 83, 78, 79, 64, 81, 97
Outlier:
Lower = Q1 - 1.5(IQR)
Upper = Q3 + 1.5(IQR)
Using a calculator :
Q1 = 78.5 ; Q3 = 88 ;
IQR = (Q3 - Q1)
(88 - 78.5) = 9.5
Outlier :
78.5 - 1.5(9.5) = values < 64.25
88 + 1.5(9.5) = values > 102.5
Hence. Outlier is 64
Removing the Outlier :
Data = 78, 79, 81, 83, 85, 91, 97
Mean = 84.85
Median = 83
Based on the result, the median is the best measure of central tendency for the data:
The simple interest on $12 000 invested at 8% per annum is $6720. Calculate the number of years for which the sum was invested. *
Answer:
7 years
Step-by-step explanation:
Given :
The Simple Interest earned, I = $ 6720
Rate of interest, r = 8% per annum
Principal amount, P = $12,000
We known that :
[tex]$I = \frac{P \times T \times r}{100}$[/tex]
Here t is the number of years of investment.
Therefore,
[tex]$t= \frac{I \times 100}{p \times r}$[/tex]
[tex]$t= \frac{6720 \times 100}{12000 \times 8}$[/tex]
t = 7
So, the sum was invested for 7 years.
. A triangle has side lengths of 8, 7, and 14. To the nearest tenth of a degree find the measure of the angle opposite the side of length 8.
Given:
The measure of three sides of a triangle are 8, 7 and 14.
To find:
The measure of the angle opposite the side of length 8.
Solution:
According to the Law of Cosine:
[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]
Let a=8, b=7 and c=14, then by using Law of Cosine, we get
[tex]\cos A=\dfrac{7^2+14^2-8^2}{2(7)(14)}[/tex]
[tex]\cos A=\dfrac{49+196-64}{196}[/tex]
[tex]\cos A=\dfrac{181}{196}[/tex]
Taking cos inverse on both sides.
[tex]A=\cos^{-1}\dfrac{181}{196}[/tex]
[tex]A=22.561328[/tex]
[tex]A\approx 22.6[/tex]
Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.
