Answer 1

Answer:

x = 15

Step-by-step explanation:

All angles add up to 180

so,

2x + 4x + 10 + 6x - 10 = 180

combine like terms

12x = 180

divide by 12

x = 15

check it by plugging it in

2x = 2(15) = 30

4x + 10 = 4(15) + 10 = 70

6x - 10 = 6(15) - 10 = 80

30 + 70 + 80 = 180

"Eight less a number is less than or equal to seventeen"

Answers

Answer:

we don't know the exact value of "a number" so we can assign it the letter value x

so we know that x-8 is less than or equal to 17

you would solve this the same way you would solve any other equation so

x is less than or equal to 25

Step-by-step explanation:

What is the outlier in the following data set:
15,11,10,8,9,1,8,7,5,4,2,3, and 37?

Answers

Step-by-step explanation:

The steps to find an outlier:

1. Put the data in numerical order.

2. Find the median.

3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts.

The median with the smallest value is called Q1. The median for all the values - usually just called the median is also called Q2. The median with the largest value is Q3.

4. Subtract...Q3 - Q1. This value is the InterQuartileRange or IQR. Remember that the range means taking the largest minus the smallest. This is a special range having to do with the quartiles.

5. Multiply...1.5 * IQR

6. Take your answer from #5 and do 2 things with it. A). Subtract it from Q1 and B) Additional to Q3.

7. Look at all your data points. If any are SMALLER than Q1 - 1.5 *IQR, they are outliers. If any are LARGER than Q3 + 1.5 *IQR, they are also outliers.

For your data....the median, Q2 is

(43+38)/2 = 40.5.

Q1 = (30+26)/2 = 28.

Q3 = (54+52)/2 = 53

The IQR is 53 - 28 = 25

1.5 * IQR = 37.5

Q1 - 37.5 = 28 - 37.5 = -9.5. There is no data value less than -9.5.

Q3 + 37.5 = 53 + 37.5 = 90.5. there is no data value greater than 90.5.

My conclusion is that there are no outliers in this data.

I hope this helps!

Find the volume of the cone 3ft and 2 ft. Round your answer to the nearest tenth if necessary. Use 3.14 for pie

Answers

Answer:

37.68 ft^3

Step-by-step explanation:

The parameters used in describing a cone is radius and height

Hence

Radius= 3ft

Height = 2 ft

The volume of a cone is given as

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

substitute

[tex]v=\frac{1}{3}*3.14*3^2*2^2\\\\v=\frac{1}{3}*3.14*9*4\\\\v=\frac{1}{3}*113.04\\\\v=37.68 ft^3[/tex]

Hence the volume is 37.68 ft^3

Find the circumference of the circle if the diameter is 27m. Use 3.14 for Pi.

Answers

Circumference= 84.78 or if needed simplified 85

Step-by-step explanation:

in this case to get the radius divide the diameter by 2 which would equal 13.5 so the formula would be

2×3.14×13.5=84.78

When Brandon went bowling, it cost $4.95 per game, plus a one-time fee to rent the shoes. Brandon played 5 games and paid $32. Write and solve linear equation to find the cost to rent the shoes.​

Answers

I think the equation would be
y=4.95x +7.25
The cost of the shoes in this instance would be 7.25.
Since he play 5 games, and each one cost 4.95, you would multiply the two getting 24.75. Since he paid 32, you would subtract what he paid total from the amount for just the games and you would get 7.25.
Using the equation y=4.95(5) + 7.25, it would equal 24.75+7.25 which is equal to 32.
I hope this is right and the answer you were looking for, have a good day.

Convert 5 ounces into kilograms. Round your answer to the nearest hundredth.

Answers

Answer:

Answer: 0.141 kilos

0.141748

Step-by-step explanation:

The conversion is 0.1417475 Kg

What is Unit conversion?

Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors which change the measured quantity value without changing its effects.

given:

5 ounces

So, to convert ounces to kilogram we have

1 ounce = 0.0283495 Kg

So, 5 ounces = 5* 0.0283495

5 ounces = 0.1417475 Kg

Hence, 5 ounces = 0.1417475 Kg

The distance between the points on the coordinate plane is 7.2 units.

What is coordinate geometry?

Coordinate geometry is the study of geometry using the coordinate points.  It provides a link between geometry and algebra through line graphs and curves.

For the given situation,

The points are (x1, y1) be (–4, –3) and (x2, y2) be (2, 1)

The formula for the distance between points,

[tex]d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]

On substituting the above points,

⇒ [tex]d=\sqrt{(2-(-4))^{2}+(1-(-3))^{2} }[/tex]

⇒ [tex]d=\sqrt{6^{2}+4^{2} }[/tex]

⇒ [tex]d=\sqrt{52}[/tex]

⇒ [tex]d=7.211[/tex] ≈ [tex]7.2[/tex]

Hence we can conclude that the distance between the points on the coordinate plane is 7.2 units.

However, warming of the ocean along the shores of New England has caused the stock of cod to disappear almost completely. According to scientists at the Gulf of Maine Research Institute, the Gulf of Maine is heating up faster than a majority of the rest of the planet's oceans. As a result of warmer ocean waters, female cod produce fewer offspring, and these fish are less likely to survive to maturity. Even though recreational cod fishing was banned in 2014, and strict limitations were placed on the number of fish commercial fishermen could catch, these measures have not been enough to protect the cod.What is the main idea of the passage?A) Because cod use to be abundant in the Atlantic, it was once the backbone of the U.S. fishing industry.B) Female cod are producing fewer offspring in the Gulf of Maine.C)Because the Gulf of Maine is warming unusually quickly, Atlantic cod are disappearing.
