18. Point B partitions AC in the ratio 1:3. What are the coordinates of C?
Please help I’ll give crown
Answers
Using proportions, the coordinates of C are given as follows: (60,41).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. 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.
Point B partitions AC in the ratio 1:3, hence:
B - A = 1/4(C - A)
The x-coordinate of C is found as follows:
12 + 4 = 1/4(x + 4)
16 = 1/4(x + 4)
x + 4 = 64.
x = 60.
The y-coordinate of C is found as follows:
5 + 7 = 1/4(y + 7)
12 = 1/4(y + 7)
y + 7 = 48
y = 41.
The coordinates of C are given as follows: (60,41).

Answers
∫45 πy2 dx is that enclose a region such that when rotated about the x -axis, a solid is produced with a volume of 18π cu units .
How do you determine a region's volume?
Depending on the axis of revolution, r=f(x) or r=f(y) and V=Adx or Ady, where A denotes the usual disc's area. The volume of the solid produced by a region under f(y) (to the left of f(y)) that is rotated around the y-axis and is bounded by the horizontal lines y=c and y=d.Volume of the solid = ∫45 πy2 dx

A group of friends wants to go to the amusement park. They have $89.50 to spend on parking and admission. Parking is $7.75, and tickets cost $27.25 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.
Answers
Answer:
7.75 +27.25p = 89.50p = 3; 3 people can go the the amusement parkStep-by-step explanation:
Given parking costs $7.75 and admission costs $27.25, you want an equation and its solution for the number of people (p) who can go to the amusement park for $89.50.
EquationThe equation relates the total of costs to the total of funds available. The cost will be the total of 7.75 for parking and 27.25p for admission for p people.
7.75 +27.25p = 89.50
SolutionThis 2-step equation is solved by subtracting 7.75, then dividing by the coefficient of p.
7.75 +27.25p = 89.50 . . . . . equation

Answers
What is the Area of Trapezoid?
The area of a trapezoid is the total space covered by its sides. An interesting point to be noted here is that if we know the length of all sides we can simply split the trapezoid into smaller polygons like triangles and rectangles, find their area, and add them up to get the area of the trapezoid. However, there is a direct formula that is used to find the area of a trapezoid if we know certain dimensions.
Area of Trapezoid Formula :
The area of a trapezoid can be calculated if the length of its parallel sides and the distance (height) between them is given.
The formula for the area of a trapezoid is expressed as,
A = 1/2 (a +b) h
where (A) is the area of a trapezoid, 'a' and 'b' are the bases (parallel sides), and 'h' is the height (the perpendicular distance between a and b)

Answers
The measure of arc NPQ is 180° while the measure of m <AOB is 69°.
What is the inscribed of a circle?An inscribed angle of a circle is an angle whose vertex is a point A on the circle and whose sides are line segments (called chords) from A to two other points on the circle.
An octagon is known to be a type of polygon that is said to have up to 8 sides. the octagon is an 8-sided polygon, also called 8-gon, in a two-dimensional plane. A regular octagon will have all its sides equal in length. Each interior angle of a regular octagon is equal to 135°. Therefore, the measure of exterior angle becomes 180° – 135° = 45°.

Beau buys a 3-pound of trail mix for a hike. he wants to make one-ounce bag of trail mix for his friends with whom he is hiking how many one-ounce bags can he make?
Answers
Using conversion, Beau can make 48 one-ounce bags of trail mix from the 3-pound trail mix he bought for the hike.
To know how much one-ounce bags of trail mix can he make from the 3-pound trail mix, convert first the amount of trail mix in pounds to ounce.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
Converting pounds to ounce,
1 pound = 16 ounces.
If Beau has 3 pounds of trail mix, equivalently, converting pounds to ounces, he has:
1 pound = 16 ounces
3 pounds = 3(16 ounces)
3 pounds = 48 ounces
If he wants to make one-ounce bag of trail mix from the 3-pound of trail mix (= 48 ounces), divide it by one ounce to get how many bags he can make.
number of one-ounce bag = 48 ounces/1 ounce
number of one-ounce bag = 48

Suppose we draw a single card from a deck of 52 fair playing cards. what is the probability of drawing an ace or a two?
Answers
The probability of getting an Ace is 1/13.
Probability of an event = number of favorable outcomes for the event/number of all possible products.
First, let's calculate the number of all possible outcomes. Randomly picking the cards could result in each of the 52 being selected. So, there are 52 possible outcomes.
But if you want an Ace in your desired event, you have four options—ace of Spades, Ace of Clubs, Ace of Hearts, and Ace of Diamonds. Therefore, the number of favorable outcomes for Aces = 4.
Therefore,
The probability of getting an Ace with a deck of 52 cards = 4/52 = 1/13.

WRITING IN MATH Explain why the order of the vertices is important when naming congruent triangles. Give an example to support your answer.
Answers
Because we are saying that the angles/edges in corresponding positions for each triangle are congruent.
Consider the triangle congruence statement below:
△ABC≅△DEFThis is actually a collection of six—yes, six—congruence statements.
They are as follows:
∠A≅∠D∠B≅∠E∠C≅∠FAB≅DEAC≅DFBC≅EFAs an example, consider the first congruence: ∠A≅∠D
This is implied by the fact that A and D are both listed first in their triangles (in the statement △ABC≅△DEF ). Similarly, B and E are in second place, so that's how we get ∠B≅∠E.A similar logic applies to the sides that have corresponding vertices.If the triangle congruence statement was as follows:
△ABC≅△FED
Then,
∠A would-be congruent to ∠F∠B would be congruent to ∠E∠C would be congruent to ∠DWe can see how changing the order of the triangle names changes which angles/edges are implied to be congruent.
This is why we must be cautious to name the triangles in the correct order. Otherwise, we risk claiming that two angles (or line segments) are congruent when they are not.Therefore, we are saying that the angles/edges in corresponding positions for each triangle are congruent.

What is the solution to the given equation?Given the equation in the question;
3/7 divided by 11/21 = 3/7 x
3/7 ÷ 11/21 = (3/7)x
To divide two fractions, multiply the first fraction by the reciprocal of the second fraction.
3/7 ÷ 11/21 = (3/7)x
3/7 × 21/11 = (3/7)x
( 3 × 21 )/( 7 × 11 ) = (3/7)x
63/77 = (3/7)x
Remove the parenthesis
63/77 = (3/7) × x/1
63/77 = ( 3 × x )/( 7 × 1)
63/77 = 3x/7
Cross multiply
63 × 7 = 3x × 77
