Given: ABC
Prove: The medians of ABC are concurrent.
What is step 10 in this proof?
Answers
Answer:
As seen , what steps you have written you just want to prove if in a triangle two medians have common point of intersection , a point P, then the third median will also pass through point P.
The point of intersection of medians is called Centroid.
The statement ahead of :Statement: Point P lies on and .
Reason: from above algebra
Point P is the intersection of three medians which is called Centroid of triangle.The Centroid divides the line from opposite vertex in the ratio of 2:1.

The speed limit is 55mph. How far can you travel in 3 hours going the speed limit? How far can you travel if you went 5 miles over the speed limit?
Answers
Answer:
If you were going the speed limit, after 3 hrs, you would go 165 miles.
If you were going 5 miles above the speed limit you would go 180 miles.
Step-by-step explanation:
55 x 3 = 165
55 + 5 = 60
60 x 3 = 180
Answer:
165miles
180miles
Step-by-step explanation:
If going 55mph for 3 hours,
55miles/hour * 3hour = 165miles
If going 60mph (5 over the limit) for 3 hours:
60miles/hour * 3hour = 180miles

Currently, Jacob’s mother is three more than nine times as old as Jacob. In eleven years, his mother will be five more than three times his age. Write a system of linear equations that models this situation. Let j represent Jacob's age, and let m represent his mother's age.
Write an equation that relates Jacob and his mother's current ages. Solve the system of equations.
What are their ages?
Answers
Answer:
Jacob is 4 years old and his mother is 40 years old.
Step-by-step explanation:
Part 1: The linear equations are and
Part 2: Solving the equations, we have, and
Part 3: Jacob is 4 years old and his mother is 40 years old.
Explanation:
Part 1: Let j represent Jacob's age, and let m represent his mother's age.
It is given that, "Jacob's mother is three more than nine times as old as Jacob". Writing it as linear equation, we have,
It is also given that, "In eleven years, his mother will be five more than three times his age". Writing it as linear equation, we have,
Simplifying this, we get,
Thus, the linear equation is
The linear equations are and
Part 2: Solving the linear equation, we get,
Substituting in
Simplifying, we get,
Hence,
Substituting in
Solving the equations, we have, and
Part 3: Since, j represents jacob and m represents the jacob's mother
Thus, Jacob is 4 years old and his mother is 40 years old.
The Mother - 40 years old
Why are the divisibility rules for 2, 3, and 5 very useful for determining prime and composite numbers
1. They are the smallest odd numbers
2. They add up to 10
3. They are prime numbers with nice divisibility rules
4. They multiply to 30
5. They can be multiplied together to make every number
Answers
Answer:
option 3.
Step-by-step explanation:
alright, ima explain each option.
1. "smallest odd numbers" 2 is an even number. that's out of the playing field.
2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.
3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]
4. they do multiply to 30, but this does not help break the composite numbers down.
5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.

Where do the slope and y-intercept show up in the tables and graphs?
Answers
Answer:
Solution: The general form of the line on a graph is y = mx+c,
where y is the coordinate of the point along the y-axis,
x is the coordinate of the point along the x-axis,
m is the slope of the line or arc tan of the angle the line makes with the x-axis, and
c is the intercept the line makes on the y-axis.
Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is
y = mx + c
6 = tan 45 * 4 + c, or
6 = 4 + c, or
c = 6–4 = 2.

We can take the reciprocal of the denominator, since the denominator itself is a fraction
The above equation can be rephrased as,
(a) / (5/8) = (3/5) / (2/3)
Taking reciprocal
8a / 5 = 3*3 / 5*2
8a / 5 = 9 / 5*2
a = 9 * 5 / 5*2*8
5’s get canceled, 2 and 8 gets multiplied in the denominator.
We will then be left with,
a = 9 / 16
I have also verified it and got the right answer.
