A triangle with vertices D, E, and F are plotted on the coordinate plane at (0, 5). (2, 0), and (-4, 2), respectively. When constructed,
medians DG and EH intersect at the point with which coordinates? Round each coordinate to the nearest tenth if necessary.
A. (-0.7, 2.5)
B. (-1, 1)
C. (-0.7, 2.3)
D. (-2, 3.5)
Given:
Vertices of a triangle are D(0,5), E(2,0) and F(-4,2).
To find:
The intersection point of medians DG and EH.
Solution:
We know that, intersection point of all the medians of a triangle is called centroid.
The formula of centroid is
[tex]Centroid=\left(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\right)[/tex]
Vertices of a triangle are D(0,5), E(2,0) and F(-4,2). So, the centroid of the triangle is
[tex]Centroid=\left(\dfrac{0+2+(-4)}{3},\dfrac{5+0+2}{3}\right)[/tex]
[tex]Centroid=\left(\dfrac{-2}{3},\dfrac{7}{3}\right)[/tex]
[tex]Centroid=\left(-0.666...,2.333\right)[/tex]
Round each coordinate to the nearest tenth.
[tex]Centroid=\left(-0.7,2.3\right)[/tex]
Therefore, the correct option is C.
Question is in picture below
Answer:
[tex] \frac{y - 18}{x - 1} = \frac{23 - 18}{1.5 - 1} = \frac{5}{0.5} = 10 \\ y - 18 = 10(x - 1) = 10x - 10 \\ y = 10x + 18 - 10 = 10x + 8 \\ \boxed{f(x) = 10x + 8}[/tex]

a factory could produce 84 toy robots in one day. They purchased some new equipment. Now they can produce 105 robots in one day. what is the percent gain?
Answer:
The answer to the question is
25 % increase in production rate
Step-by-step explanation:
To solve the question, we note that
Initial number of products = 84 toy robots per day
Present production rate = 105 robots per day
The percentage increase is given by the increase in production rate divided by the original production rate multiplied by 100
Where increase in production rate = 105 - 84 = 21
Percentage increase = 21/84 ×100 = 25 % increase
Evaluate -x + 8 for x = 5.
Answer:
3 is the answer
Step-by-step explanation:
-(5)+8
-5+8=3
you just change x for 5 and go from there
In this problem, you have to use substitution!
-x + 8, when x = 5
1) Substitute the value of 'x' with '5'
-x + 8
= -5 + 8
2) Reverse the expression to make it easier to solve [optional]
-5 + 8
= 8 - 5
3) Solve!
8 - 5
= 3
Your answer is 3
I hope this helps!

a quadrilateral has 2 angles that measure 100 and 60 degrees the other angles have a ratio of 3:17 . what are the measures of those angles?
Answer:
30° , 170°
Step-by-step explanation:
Let the remaining two angles be 3x & 17x. As it is a quadrilateral , the sum of all the angles of quadrilateral is 360°. So,
[tex]3x + 17x + 60 + 100 = 360[/tex]
[tex] = > 20x + 160 = 360[/tex]
[tex] = > 20x = 360 - 160 = 200[/tex]
[tex] = > x = \frac{200}{20} = 10[/tex]
Putting the value of x , remaining angles are
(3×10 = 30°) & (17×10 = 170°)
Step-by-step explanation:
the missing angles 3:173x+17x+60+100=360°20x+160=360°20x=360-16020x=200°divide both sides by 20X=10substitute X=10 in 3x and 17x3(10)=30°17(10)=170°PLEASE HELP WILL MARK BRAINLIEST!!!!

Two sisters, Crystal and Alexa, are going to a strange birthday party. Instead of birthday cake,
pairs of party guests are each served a large chewy fruit worm to share according to their ages.
Since the sisters are not the same age, they do not share their fruit worm equally.
Crystal is 12 years old and Alexa is 6 years old. Their chewy fruit worm has 18 segments.
According to their ages, Crystal gets 12 segments and Alexa gets 6 segments. The ratio of the
girls' shares of the worm, 12 to 6, is equivalent to the ratio of their ages, 12 to 6.
• According to the rule, how would the girls share a 9-segment chewy fruit worm?
Since Crystal's age is two times Alexa's age, Crystal gets twice as many segments as Alexa.
The ratio of Crystal's segments to Alexa's segments is 12 to 6 or 2 to 1.
. The ratio 2 to 1 is a unit rate. What do the numbers 2 and 1 mean for the sisters?
12 to 6
In this Problem you will explore situations that involve fractions and ratios.

For the school play, the advance tickets cost 3, while tickets at the door cost 5. Thirty more tickets were sold at door than in advance, and was collected. How many of each kind of ticket were sold? Write your answer in a sentence.
Answer:
Number of tickets sold in advance = 310
Number of tickets sold at the door = 340
Step-by-step explanation:
Note: This question is not complete. The complete question is therefore provided before answering the question as follows:
For the school play, the advance tickets cost $3, while tickets at the door cost $5. Thirty more tickets were sold at the door than in advance, and $2630 was collected. How many of each kind of ticket were sold?
The explation of the answer is now given as follows:
Let a represents number of tickets sold in advance. Therefore, we have:
a = number of tickets sold in advance at $3 each
a + 30 = number of tickets sold at the door at $5 each
The total amount collected can be represented by this equation:
3a + 5(a + 30) = 2630
Solving for a, wee have:
3a + 5a + 150 = 2630
8a = 2630 - 150
8a = 2,480
a = 2,480 / 8
a = 310
Therefore, this implies:
Number of tickets sold in advance = 310
Number of tickets sold at the door = a + 30 = 310 + 30 = 340

an equation of a line that passes through the point (15,2) and is perpendicular to the line -10x+8y = 3?
Answer:
y = -⁴/₅x + 14Step-by-step explanation:
Changing to slope-intercept form:
-10x + 8y = 3 {add 10x to both sides}
8y = 10x + 3 {divide both sides by 8}
y = ⁵/₄x + ³/₈
Two lines are perpendicular if the product of their slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
y = ⁵/₄x + ³/₈ ⇒ m₁=⁵/₄
⁵/₄×m₂ = -1 ⇒ m₂ = -⁴/₅
The line y=-⁴/₅x+b passes through point (15, 2) so the equation:
2 = -⁴/₅×15 + b must be true
2 = -12 + b
b = 14
Therefore equation in slope-intercept form:
y = -⁴/₅x + 14

A battery factory typically produces 12,000 batteries per day and uses 50 boxes for packing the battiest. If the number of boxes needed for packing is proportional to the number of batteries produced, how many more boxes would be needed in a day when 18,000 battiest are produced
Answer:
Number of extra boxes= 120
Step-by-step explanation:
Giving the following information:
Batteries per box= 50
Number of batteries= 18,000
Number of batteries in ecxess= 6,000
We need to calculate the number of boxes required to cover the 6,000 extra batteries:
Number of extra boxes= number of batteries / batteries per box
Number of extra boxes= 6,000 / 50
Number of extra boxes= 120
A copy machine makes 36 copies per minute. How long does it take to make 126 copies?
Answer:
It will take 3.5 minutes to make 126 copies
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can do 126/36 to get our answer since 126 is the total copies and 36 is the copies we can do in a minute. 126/36 = 3.5 so it will take 3.5 minutes.
Find the angle with the smallest measure in △ VUW. Name the angle using three letters
Answer:
∠VUW
Step-by-step explanation:
A triangle is a three sided polygon with three angles. Types of triangles are obtuse, scalene, isosceles, equilateral and so on.
In triangle VUW, since VU = WU, hence it is an isosceles triangle. In an isosceles triangle, two sides of the triangle are equal.
The size of an angle depends on its opposite side, the higher the opposite side the higher the angle. Since In triangle VUW, VU = 9, WU = 9, VW = 5. Since VW is the smallest side, the angle opposite to VW is the smallest angle.
Hence the smallest angle = ∠VUW
