Using proportions, the coordinates of point C are given as follows:
C(0, -0.67).
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
For this problem, the points are given as follows:
A(-4,-6), B(5,6), C(x,y).
The ratio of AC to CB is of 4:5, hence the following equation is constructed:
C - A = 4/9(B - A).
As the ratio of 4:5 means that the distance is 4/(4 + 5) = 4/9.
The x-coordinate of C is found applying the above equation as follows:
x + 4 = 4/9(5 + 4)
x + 4 = 4
x = 0.
The y-coordinate of C is also found applying the equation, as follows:
y + 6 = 4/9(6 + 6)
y + 6 = 5.33.
y = -0.67.
Hence the coordinates of point C are given as follows:
C(0, -0.67).

Determine which answer in the solution set will make the equation true.
4p + 5 = 6p − 15
S: {−10, 0, 10, 20}
A: 0
B: −10
C: 20
D: 10
Answer:
d) 10
Step-by-step explanation:
Let's solve the problem,
→ 4p + 5 = 6p - 15
→ 6p - 4p = 5 + 15
→ 2p = 20
→ p = 20/2
→ [ p = 10 ]
Hence, option (d) is correct.

how do you find the nth term of 70, 110, 150, ….
Answer: an=40(n-1)+70
Step-by-step explanation:
70, 110, 150, ….
Notice the terms get bigger by 40 as the sequence progresses. Hence, we can model this sequence with a linear equation. y=40(x-1)+70 where y=term value, x=term number and 70 is the first term.
y=40(x-1)+70
an=40(n-1)+70 ==> an=term value/nth term. n=term number

Scientists are drilling a hole in the ocean floor to learn more about the Earth's history. Currently, the hole is in the shape of a cylinder whose volume is approximately 3500 cubic feet and whose height is 2.9 miles. Find the radius of the hole to the nearest hundredth of a foot. (Hint: Make sure the same units of measurement are used.)
The radius of the hole is 0.07 feet.
What is the radius?A cylinder is a three-dimensional object that is made up of a prism and a circular base.
Volume of a cylinder = πr²h
Radius = √volume / (π x h)
Where:
π = pi = 22/7r = radiush = heightThe volume of the hole and the height of the hole are in different dimensions. Thus, the height of the hole has to be converted to feet.
1 mile = 5280 feet
5280 x 2.9 = 15,312 feet
3500 / (22/7 x 15,312) = 0.07 feet

For a sporting event 6,000 tickets were sold, and the proceeds were $78,000. Tickets for children 16 and younger, were $8, adults were $16, and seniors 60 and older were $12. There were 2 times more adults than children at the sporting event.
What system of equations represents the number of children, c, adults, a, and seniors, s, that attended the sporting event?
Responses
c+a+s=6,000
8c+12a+16s=78,000
2a=c
c+a+s=6,000
8c+16a+12s=78,000
a=2c
c+a+s=6,000
8c+12a+16s=78,000
a=2c
c+a+s=6,000
8c+16a+12s=78,000
2a=c
Option 2 is the answer.
No. on tickets sold = 6000
Proceedings of the tickets sold = $78,000
Cost of tickets for children = $8
Cost of tickets for adults = $16
Cost of tickets for seniors = $12
2 times more adults were present than the children.
Let the number of children be 'c.'
Let the number of adults be 'a.'
Let the number of seniors be 's.'
Since 2 times more adults were present than the children, we get the equation,
a = 2c
No. of tickets sold will be equal to the total no, of people.
∴ c + a + s = 6000
The proceedings will be equal to the sum of the amounts and number of people who bought tickets with that amount,
∴ 8c + 16a + 12s = $78,000
Thus, we have the three equations,
c + a + s = 6000
8c + 16a + 12s = $78,000
a = 2c
This series of equations are given in option 2 Thus, option 2 is the answer.

we get 6 = 6 , in 42= 6x7 using commutative law of multiplication.
What do associative law and commutative law mean?
The order of some mathematical operations is addressed by the commutative property. We can write the binary operation as a + b = b + a. The associative attribute, on the other hand, deals with the grouping of numbers in an operation. For instance, we could write it as (a + b) + (a + b + c).This law states that no matter how the numbers are arranged, the outcome of multiplying two integers remains the same. So A.B = B.A. Examples include: 1 + 2 + 1 + 2 + 4 + 5 + 4 + 20.using the Commutative Law of Multiplication.

Step-by-step explanation:
We have the equation
[tex]x + 9 = 2(x-1)^2[/tex]
[tex](x-1)^2 = x^2-2x+1[/tex] using the formula [tex]\left(a-b\right)^2=a^2-2ab+b^2[/tex]
[tex]x + 9 = 2(x^2-2x\cdot \:1+1^2)[/tex] = [tex]2x^2-4x+2[/tex]

[tex]2x^2 -4x -7 = x[/tex]

Now, because the conditional and converse are true, then we have a biconditional relation between P and Q.
From that, we conclude that the truth values for the two above statements is true for both
What are the truth values of the contrapositive and inverse statements?
A conditional statement is of the form:
If P, then Q.
The inverse statement is:
if Q, then P.
We assume that these two are true.
An example of this is:
P = a number is even.
Q = a number is a multiple of 2.
Then the two above statements are:
conditional: If a number is even, then the number is a multiple of 2.converse: if a number is a multiple of 2, then it is even.Now the inverse statement is:
if not P, then not Q.
The contrapositive is:
If not Q, then not P.
Now, because the conditional and converse are true, then we have a byconditional relation between P and Q.
From that, we conclude that the truth values for the two above statements is true for both, but let's check with our propositions:
Inverse: If a number is not even, then it is not a multiple of 2. (this is true)
Contrapositive: If a number is not multiple of 2, then it is not even (also true).
