A secant line contains a chord ___
always
never
sometimes
Answer:
A secant line contains a chord always
Step-by-step explanation:
A line intersecting in two points is called a secant line, in one point a tangent line and in no points an exterior line. A chord of a circle is the line segment that joins two distinct points of the circle. A chord is therefore contained in a unique secant line and each secant line determines a unique chord.
Answer:
A secant line contains a chord ___ always

PWEEESE HELP FOR BRAINLIEST PLEASEEEEEE
Answer:
4.0541
Step-by-step explanation:
I don't know if this is correct but this is what I got.
You would take the error and divide it by the theoretical value and then multiply that by 100.
7.7 - 7.4 = 0.3
0.3 ÷ 7.4 = 0.04054054
0.04054054 x 100 = 4.05405405 (simplify) = 4.0541%

In each box, 20% of the total candies are grape flavored.
In a box of 45 candies, how many are grape flavored?
Enter the missing value in the box to complete the ratio table.
Answer:
9
Step-by-step explanation:
20 x 5 = 100
45/5 = 9
9 to 20 = 11
45 to 100 = 55
55 = 5<--- Linear
11

Triangle ABC is transformed to triangle A′B′C′, as shown below: A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes. A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0. A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0. Which equation shows the correct relationship between the measures of the angles of the two triangles? The measure of angle CAB = The measure of angle C prime B prime A prime The measure of angle BCA = The measure of angle A prime B prime C The measure of angle CAB = The measure of angle C prime A prime B prime The measure of angle BCA = The measure of angle C prime A prime B prime
Answer:
The measure of angle BCA = The measure of angle C prime A prime B prime
Step-by-step explanation:
The correct relationship between the measures of the angles of the two triangles is;
The measure of angle BCA = The measure of angle C prime A prime B.
Given thatTriangle ABC is transformed to triangle A′B′C′, as shown below:
A coordinate grid is shown from negative 4 to 0 to 4 on both x- and y-axes.
A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.
A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
We have to determineWhich equation shows the correct relationship between the measures of the angles of the two triangles?
According to the questionTriangle ABC is transformed to triangle A′B′C′, as shown below:
Here the triangle ABC is similar A'B'C' are similar triangles.
For similar triangles angles are congruent.
A triangle ABC has A at ordered pair negative 1, 3, B at ordered pair 0, 1, C at ordered pair negative 3, 0.
A triangle A prime B prime C prime has A prime at ordered pair negative 1, negative 3, B prime at ordered pair 0, negative 1, C prime at ordered pair negative 3, 0.
Therefore,
<BAC = <B'A'C'
<ABC = <A'B'C'
<ACB = <A'C'B'
Hence, The correct relationship between the measures of the angles of the two triangles is The measure of angle BCA = The measure of angle C prime A prime B.

PLS I NEED HELP ON THIS QUESTION
Answer:
Step-by-step explanation:
First, you should find the angle x because it will help in solving the angle y. A straight line adds up to 180 degrees, therefore x+y = 180
For the triangle on the left, sum up the angles and set it to 180 degrees.
60 + 38 + x = 180
x = 82 degrees
Now solve for y by doing this
82 + y = 180
y = 98 degrees
While I'm here, Ill solve for z because it will most likely ask in the next question.
26 + 98 + z = 180
z = 56 degrees

Step-by-step explanation:
Answer:
so you would add $129 to $20 then you add p to the $20 because it doesnt say how many pairs he sold so we need to add an exponent. But then you need to put all that into and equation whihc leads you to get the answer of

Here are two points (-3,4),(1,7) What is the slope of the line between them?
Answer:
3/4
Step-by-step explanation:
The solution is Option B.
The slope of the line between the points P ( -3 , 4 ) and Q ( 1 , 7 ) is 3/4
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P = P ( -3 , 4 )
Let the second point be Q = Q ( 1 , 7 )
Now , the slope of the line between the two points is given by the formula ,
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 7 - 4 ) / ( 1 - ( -3 ) )
On simplifying the equation , we get
Slope m = 3 / 4
Therefore , value of m is 3/4
Hence , slope of the line is 3/4
