Answer:

it is 7.5km

Step-by-step explanation:

This is because it is a right angle triangle (dotted lines) so the straight long line is the same length as the diagonal line.

Answer:

y = 2x - 5

Step-by-step explanation:

Using the slope intercept formula y2 - y1 / x2 -x1...

You get a slope of 2 so y = 2x +b

Then to find b the intercept, you plug in one of the coordinates like so...

1 = 2(3) + b

Then solve to get an intercept of -5.

So the slope-intercept form would be...

y = 2x - 5

Answer:

The angles have measurements 36, 72, 108, 144, and 180.

Step-by-step explanation:

Pentagon has 5 sides and 5 angles.

The amount of triangles formed by choosing one vertex and drawing from that vertex to every nonadjacent vertex is 3.

3(180)=540 which is the sum of the angles in a pentagon.

So since the ratio is 1:2:3:4:5, that means the angles are 1x,2x,3x,4x, and 5x.

We have the equation 1x+2x+3x+4x+5x=540 to solve.

15x=540

Divide 15 on both sides:

x=540/15

x=36

1x=36

2x=72

3x=108

4x=144

5x=180

The angles have measurements 36, 72, 108, 144, and 180.

Given:

3 qt/min

To find:

The conversion of 3 qt/min to gallons per hour.

Solution:

We know that,

1 quart = 0.25 gallons

60 minutes = 1 hour

1 minute = [tex]\dfrac{1}{60}[/tex] hour

Using these conversions, we get

[tex]3 \dfrac{qt}{min}=\dfrac{3\times 0.25}{\dfrac{1}{60}}\ \dfrac{gal}{h}[/tex]

[tex]3 \dfrac{qt}{min}=3\times 60\times 0.25\ \dfrac{gal}{h}[/tex]

[tex]3\ qt/min=45\ gal/h[/tex]

Therefore, the correct option is A.

Answer:

- 13[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying [tex]\sqrt{54}[/tex]

[tex]\sqrt{54}[/tex]

= [tex]\sqrt{9(6)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{6}[/tex]

= 3[tex]\sqrt{6}[/tex]

Then

2[tex]\sqrt{6}[/tex] - 5[tex]\sqrt{54}[/tex]

= 2[tex]\sqrt{6}[/tex] - 5 (3[tex]\sqrt{6}[/tex] )

= 2[tex]\sqrt{6}[/tex] - 15[tex]\sqrt{6}[/tex]

= - 13[tex]\sqrt{6}[/tex]

Answer:

6.5237 feet.

Step-by-step explanation:

initial depth of river H = 6.7 ft

In  1847 it dropped 9%, this means the new depth will be 91% of 6.7

that is (91/100)×6.7 = 6.097 ft

Now in the year , 1848 the depth gain rose by 7%, this means now the new depth 107% of 6.097

= (107/100)×6.097 = 6.5237 feet.

Therefore, new of the depth of river in 1848 = 6.537 ft

Answer:

16642.1 feets

Step-by-step explanation:

Given :

Elevation of Mt. Wilson = x

If the elevation of snow crest = y

Snow crest = 11,508.21 feet higher than Mt. Wilson

Hence, y = 11,508.21 + x

The elevation of Mt. Wilson, x = y - 11,508.21  feets

From the table, elevation of Snow crest = 28,150.31 feets = y

Hence, The elevation of Mt. Wilson, x = y - 11,508.21  feets

x = 28,150.31 - 11,508.21

x = 16642.1 feets

Answer:

80

Step-by-step explanation:

Answer:

V = 803.8 cm^3

Step-by-step explanation:

h = 12cm

r = 8cm

V = [tex]\frac{1}{3}[/tex] [tex]\pi[/tex][tex]r^{2}[/tex]h

V =  [tex]\frac{1}{3}[/tex] [tex]\pi[/tex][tex](8)^{2}[/tex] (12)

V = 4 [tex]\pi[/tex] (64)

V = 803.84

Answer:

800

Step-by-step explanation:

[tex]V=\pi r^{2} \frac{h}{3}[/tex]

[tex]V=\pi 8^{2} \frac{12}{3} \\V=\pi (64)(4) = 256\pi[/tex]

256π = 804.247719319

To the nearest tenth: 800

The piece of data from the data set is an outlier, if there is one is that there are no outliers. The correct option is D.

The interquartile range is a measure of statistical dispersion, or the spread of data, in descriptive statistics.

To identify outliers, we first need to calculate the median and the interquartile range (IQR) of the data set.

The median is the middle value of the data set when it is arranged in order. If there is an even number of values, the median is the average of the two middle values.

First, we arrange the data set in order:

{15, 20, 25, 30, 35, 40, 45, 45, 50, 55, 60}

The median is the middle value, which is 40.

Next, we calculate the IQR, which is the difference between the third quartile (Q3) and the first quartile (Q1) of the data set.

Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set. To calculate Q1 and Q3, we first split the data set into two halves:

Lower half: {15, 20, 25, 30, 35}

Upper half: {40, 45, 45, 50, 55, 60}

Q1 is the median of the lower half, which is 25. Q3 is the median of the upper half, which is 50.

So, the IQR is:

IQR = Q3 - Q1 = 50 - 25 = 25

To identify outliers, we use the following rule: any value that is less than Q1 - 1.5 x IQR or greater than Q3 + 1.5 x IQR is considered an outlier.

Q1 - 1.5 x IQR = 25 - 1.5 x 25 = -12.5

Q3 + 1.5 x IQR = 50 + 1.5 x 25 = 87.5

We see that none of the values in the data set are less than -12.5 or greater than 87.5. Therefore, there are no outliers in this data set.

Thus, the answer is D) There are no outliers.
