stove
sink
refrigerator
the centroid
the orthocenter
HELPPPPPPPPPP PLEASEEEEEEE
Answer:
Circumcenter describes the point equidistant to the refrigerator, stove and the sink
Step-by-step explanation:
The basic construction of the circumcenter is to identify the midpoints of the original triangle. This circumcenter is the point where all the perpendicular bisector of the sides of the triangle intersects. For an triangle that is acute-angled, its circumcenter will lie inside the triangle. For an obtuse-angled triangle, the circumcenter lies outside of the triangle
, In a right-angled triangle, Circumcenter lies at the midpoint of the hypotenuse side of triangle.
To Find the circumcenter of the triangle

In his free time Gary spends 10 hours per week on the internet and 9 hours per week on video games. If Gary has 5 hours of free time per day what percent of free time is he using to play video games and use the internet
Final answer:
Gary spends approximately 54.29% of his free time on video games and the internet.
Explanation:
To find the percentage of free time that Gary spends on video games and the internet, we need to calculate the total number of hours he spends on these activities and divide it by the total number of hours of free time he has.
First, calculate the total number of hours Gary spends on video games and the internet: 10 + 9 = 19 hours.
Next, calculate the total number of hours Gary has for free time in a week: 5 hours per day x 7 days = 35 hours.
To find the percentage, divide the total number of hours spent on video games and the internet by the total number of hours of free time and multiply by 100: (19 / 35) x 100 = 54.29%.
Therefore, Gary spends approximately 54.29% of his free time on video games and the internet.
To find the percentage of free time that Gary is using to play video games and use the internet, calculate the total free time and the proportion of time spent on video games and internet use.
Explanation:To find the percentage of free time that Gary is using to play video games and use the internet, we need to calculate the total amount of free time Gary has and then determine the proportion of that time spent on video games and internet use.
Gary spends 10 hours per week on the internet and 9 hours per week on video games. This is a total of 10 + 9 = 19 hours per week.
Since Gary has 5 hours of free time per day, he has a total of 5 * 7 = 35 hours of free time per week.
To find the percentage, we divide the time spent on video games and internet use (19 hours) by the total free time (35 hours) and then multiply by 100. So, the percentage is (19/35) * 100 = 54.28% (rounded to two decimal places).

Which values of x are solutions to the inequality?
x < -200. select each correct answer
A. x = - 120
B. x = - 210
C. x = -200
D. x = -201
Answer:
B. [tex]x=-210[/tex]
D. [tex]x=-201[/tex]
Step-by-step explanation:
Given:
The inequality for 'x' is given as:
[tex]x<-200[/tex]
The above inequality tells us that, the value of the variable 'x' is less than -200.
-200 is a negative number. So, for a negative number, the larger the value of the number, the smaller the number is.
Example: -2 is less than -1 although 2 has a greater magnitude than 1.
Therefore, the numbers that are less than -200 are -210 and -201.
So, the values of 'x' that satisfy the given inequality are -201 and -210

Step-by-step explanation:
D = all real numbers R= {y|y>=1}.
All polynomials have domain of all real numbers.

Answer: The diver is 23 feet under sea level
Step-by-step explanation:
If we draw a vertical number line (image attached), where point 0 is sea level (the diver's initial position), the first point under sea level is -20, since we are told it dives a distance of 20 ft (the negative sign is only to indicate the direction, since a distance cannot be negative).
Then, the diver goes 10 ft deep. This means now it is 30 ft under sea level and the second point is -30.
After that the diver swims up 12 ft, hence we have to count 12 points up in our number line and the corresponding point is -18.
Finally, the diver swims 5 ft lower and keep that position. Hence, we have to count 5 points below point -18 in the number line, resulting in the last point: -23.
This means the diver's final position is 23 feet under sea level.
If we want to prove it with numbers, we can do it as follows:
20 ft (down)+10 ft (down)-12 ft (up)+5 ft (down)=23 ft

Answer:
Full bottle can fill 34 ounces water and 27.2 ounces left in the bottle
Step-by-step explanation:
Full bottle : 100%
6.8 ounces: 20%
100% / 20% = 5
Full bottle = 6.8 x 5 = 34 ounces
water remain in bottle = 34 -6.8 = 27.2 ounces
There is 34 ounces of water in the bottle initially and this can be determined by using the unitary method.
Given :
Diego pours 6.8 ounces of water from a full bottle.He estimates that he poured out 20% of the water in the bottle.The following steps can be used in order to determine the total amount of water in the full bottle:
Step 1 - The unitary method can be used in order to determine the total amount of water in the full bottle.
Step 2 - According to the given data, Diego pours 6.8 ounces of water from a full bottle which is the 20% of the water in the bottle.
Step 3 - If 20% is 6.8 ounces of water than the 100% is given by:

A conical tent has a radius of 10.4 ft and a height of 8.4 ft. Doubling which dimensions will quadruple the volume of the tent?
Answer: Doubling the radius.
Step-by-step explanation:
The volume of a cone can be found with the following formula:
[tex]V=\frac{1}{3}\pi r^2h[/tex]
Where "r" is the radius and "h" is the height of the cone.
Let's find the volume of the conical tent with a radius of 10.4 feet and a height of 8.4 feet.
Identifiying that:
[tex]r=10.4\ ft\\\\h=8.4\ ft[/tex]
You get this volume:
[tex]V_1=\frac{1}{3}\pi (10.4\ ft)^2(8.4\ ft)\\\\V_1=951.43\ ft^3[/tex]
If you double the radius, the volume of the conical tent will be:
[tex]V_2=\frac{1}{3}\pi (2*10.4\ ft)^2(8.4\ ft)\\\\V_2=3,805.70\ ft^3[/tex]
When you divide both volumes, you get:
[tex]\frac{3,805.70\ ft^3}{951.43\ ft^3}=4[/tex]
Therefore, doubling the radius will quadruple the volume of the tent.
Company charges $80 per hour fee for computer repair plus a 1 time service fee. The total for 3 hours was $290. Write the point slope form of an equation to find the total fee y for any number of hours x
Answer:
y=80x+50 for the one time service fee.
Anytime after that would be y=80x
Step-by-step explanation:
Y is how much the total is and 80 is how much it is an hour. X is the number of hours worked. With the first time fee of $50, your equation would be y=80x+50. Anytime after that, excluding the “one time fee,” the equation would be y=80x.
