Answer:
The length of JF = 3
Step-by-step explanation:
We know that the point of intersection of the Medians of a triangle is called the centroid of a triangle.
Thus,
For the given triangle ΔHIJ,
Point K is the centroid of the triangle.We also know that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.
Also, each Median is split into two parts such that the longer part is 2 times the length of the smaller part.
In our case,
The median JF is split into two parts such that the longer part JK is 2 times the length of the smaller part KF.
In other words,
JF = KF + JK
Given KF = 1
Also, the longer part JK is 2 times the length of the smaller part KF.
i.e.
JK = 2 KF
JK = 2(1) ∵ KF = 1
JK = 2
Thus, substituting KF = 1 and JK = 2 in JF = KF + JK
JF = KF + JK
JF = 1 + 2
JF = 3
Therefore, the length of JF = 3

All of the triangles Angles should equal 180!
The middle triangle has 39°,x°,and y°.
The triangle on the right has 121°,39°, and w°
First you’ll solve for y° using the left triangles values which will be 40°.
Then you will solve for the x° using the middle triangles values which will be 101°
Lastly you’ll solve for the w° using the triangle on the right which will be 20°

POSSIBLE POINTS: 100 A theater has group prices for tickets. The first ticket will cost $8 while each additional ticket will cost $5. Write a rule to model the situation. Then use the rule to find how the total cost of 13 tickets. Let n represent the number of tickets and c represent the total cost
Answers
Answer:
c = 8+5n
total cost of 13 tickets = $68
Step-by-step explanation:
c = 8 + 5(12)
c = 8 + 60
c = 68

please someone help me with this
Answers
First, find the slope using the equation, y2 - y1 / x2 - x1
1-5 / 4 - - 4 = -4/8 = -1/2
plug this into slope intercept form
y = -1/2x + b
Next use one of the points to find b using point-slope form. I will use (4,1)
y - y1 = m ( x - x1)
y - 1 = -1/2 (x - 4)
y -1 = -1/2x + 2
+1 +1
y = -1/2x + 3 is your equation

6 identical toys weigh 1.8kg. a) convert 1.8kg to grams. b) what is the weight of one toy? Give your answer in grams. c) how much would 4 toys weigh? Give your answer in kilograms
Answers
Answer: a) 1800g b) 300g c) 1200g
Step-by-step explanation:
a) 1.8 x 1000 = 1800g
b) 1800g / 6 toys= 300g > the weight of one toy
c) 300g x 4 toys = 1200g / 1000 = 1.2 kg
Answer:
a. 1.8kg to grams
1000g =1kg
x =1.8kg
cross multiply
x = 1.8 x 1000
x= 1800g
b. weight of one toy
6 toys = 1800g
1 toy = 1800÷6
1 toy = 300g
c. 1kg = 300g
4toys = x
x = 4 x 300
x = 1200g
1200g to kilogram
1000g = 1kg
1200g = x
cross multiply
1000x = 1200
x = 1200÷1000
x = 1.2kg

Answer:
Step-by-step explanation:
1). Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of the line passing through two points (2, -10) and (-2, 18) will be,
m = [tex]\frac{-10-18}{2+2}[/tex]
m = -7
2). From the table attached,
Slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of line passing through (4, -6) and (0, -2) will be,
Slope = [tex]\frac{-6+2}{4-0}[/tex]
Slope = -1

For an equation like:
y = a*x + b
a is the slope, and this is the rate of change of the function.
For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.
Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.

Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden. Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam. This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears. Which batch of jam tasted more like cranberries?
Answers
Answer:
The batch of jam from this summer
Step-by-step explanation:
Every summer, Ronald makes cranberry-pear jam with the fruit he collects from his garden.
For last summer
Last summer, he used 3 cups of cranberries and 5 cups of pears to make his jam.
Hence,
5 cup of pears = 3 cups of cranberries
1 cup of pears = x
Cross Multiply
5x = 3
x = 3/5
x = 0.6
1 cup of pears = 0.6 cup of cranberries
For this summer
This summer, Ronald decided to make an even larger batch using 5 cups of cranberries and 8 cups of pears.
Hence,
8 cup of pears = 5 cups of cranberries
1 cup of pears = x
Cross Multiply
8x = 5
x = 5/8
x = 0.625
1 cup of pears = 0.625 cup of cranberries
From the above calculation we can see that the quantity of cranberries to 1 cup of pears from this summer is higher than that of last summer
Therefore, the batch of jam that tasted more like cranberries is the batch of jam from this summer
Answer:
This summer’s batch jam tasted more like cranberries.
