The number of strips Emma will be able to make 22.5 i.e. 22.
What is strips?The set of points in the plane between two parallel lines in the plane. The x,y coordinates plane of the points in the stripe satisfy the inequality C1 < . Ax + By < C2, where A, B, C1, C2 are certain constants and both A and B cannot be zero. The strip number is typically used in preparing the data for matching (or as a matching transformation within the matching processor). For text data that has numbers in the data but that you know are irrelevant, removing the numbers before matching is useful. As an abstract topological space, the Mobius strip can be embedded in three-dimensional Euclidean space in various ways. The twist is greater than 1 or the centerline is knotted.According to question

Find the slope of the line that passes through (2, 7) and (-4, 19).
m =
The slope, m, of the line that passes through (2, 7) and (-4, 19) is -2.
According to the question,
We have the following information:
A line is passing through two points (2,7) and (-4,19).
We know that the slope of the line is denoted by m and the following formula is used to find the slope of the line passing through two points:
m = (y2-y1)/(x2-x1)
(More to know: we can also easily find the equation of the line using the slope given and the points from which the line is passing.)
In this case, we have x1 = 2, y1 = 7, x2 = -4 and y2 = 19.
m = (19-7)/(-4-2)
m = 12/(-6)
m = -2
Hence, the slope, m, of the line that passes through (2, 7) and (-4, 19) is -2.

Please help me! It is about proofs, SSS and SAS.
The two given triangles are congruent because of SAS.
What does congruency mean?In geometry, two figures or objects are congruent if their shapes and sizes match, or if one is the mirror image of the other. Both of the bread slices have the same shape and size when stacked on top of the other. Congruent refers to having the same precise size and shape. Having the same size and shape makes two shapes congruent. The mirror image of one shape is the same as the other if the two shapes are congruent.
The given triangles are RTP and STP
P is the midpoint of RS and TP is the altitude of triangle RTS.
In the triangles RTP and STP
TP = TP (common)
∠RPT = ∠ SPT (90°)
RP = SP (median divides the side equally)
So, both triangles are congruent using SAS property.

From the diagram below, if AC is a tangent line, and if PD = 8 and DC = 9, find the length of BC.
Given,
PD = 8 and DC = 9
Required
The length of line BC.
Here, PB and PD are the ardius of the circle. By the definition of circle, the measure of all radius is equal.
So, PB = PD = 8.
The tangent is always perpendicular to the radius at the point of tanjency.
By the pythagoras theorem,
[tex]\begin{gathered} PB^2+BC^2=PC^2 \\ 8^2+BC^2=(17)^2 \\ BC^2=289-64 \\ BC^2=225 \\ BC=15 \end{gathered}[/tex]Hence, the measure of BC is 15 units.
Write an equation in slope-intercept form that represents the data in the table.
The equation of the line that represents the data in the table is y = 30x + 30.
How to determine the equation of line from points?The formula for equation of line is expressed as;
y = mx + b
Where m is slope and b is y-intercept
From the data;
Point 1( 0,30 )
x₁ = 0y₁ = 30Point 2( 2,90 )
x₂ = 2y₂ = 90First, we determine the slope.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 90 - 30 )/( 2 - 0 )
Slope m = ( 60 )/( 2 )
Slope m = 30
Next, we determine the y-intercept b by substituting the given values into the equation of line formula.
y = mx + b
30 = (30)0 + b
30 = b
b = 30
Now, plug these values into y = mx + b to determine the equation of the line.
y = mx + b
y = 30x + 30
Therefore, y = 30x + 30 is the equation of the line.

m=2A number time 5 less that number has a product of -4. What are the two numbers?
Let the first number be x.
The second number is 5 times less than x => x - 5
Therefore, we can write the statement as
[tex]\begin{gathered} x\times(x-5)=-4 \\ x^2-5x=-4 \\ \therefore \\ x^2-5x+4=0 \end{gathered}[/tex]Solving the quadratic equation:
Let us replace -5x in the equation with -4x and -x to be able to factorize.
Hence,
[tex]\begin{gathered} x^2-4x-x+4=0 \\ x(x-4)-1(x-4)=0 \\ (x-4)(x-1)=0 \\ \text{Therefore} \\ x-4=0\text{ } \\ or \\ x-1=0 \end{gathered}[/tex]Hence,

As per the given interest rates, she have to pay $103.95 in fees for her actively managed fund.
Interest:
Interest means the amount to be paid on the borrowed money or the amount received on the money lent.
Given,
Alizeh invests $9,000 in an actively managed mutual fund that has an annual expense ratio of 1.1%. The investment earns a 5% rate of return.
Here we need to find the fees for her actively managed fund.
First we have to change rate of return percent to decimal form,
That is,
5% = 0.05
Now, we have to multiply the amount and decimal to get Alizeh 's profit,
=> 9000 x 0.05
=> 450
Therefore, the fund's total after 1 year, including initial investment and profit is
=>9000 + 450
=> 9450.
Now, we have to change fee percent that is the expense ratio into decimal form,
=> 1.1% = 0.011
Therefore, the fees for her fund is,
=> 9450 x 0.011
=> 103.95
Therefore, she have to pay $103.95 for her managed fund.

To find
A) The value of x.
B) The value of x.
Explanation:
A) It is given that,
Angle A and angle B are supplementary.
Then,
[tex]\angle A+\angle B=180\degree[/tex]Hence, the error is in the statement,
Since the angles are supplementary, when added together they equal 90.
As, the correct answer is when added together they equal 180.
That implies,
[tex]\begin{gathered} x+6+7x+30=180 \\ 8x+36=180 \\ 8x=180-36 \\ 8x=144 \\ x=\frac{144}{8} \\ x=18\degree \end{gathered}[/tex]Hence, the value of x is 18 degrees.
B) It is given that,
From, the figure the given angles are interior angles.
Also, the interior angles on the same side of the transversal is supplementary.
Which means when you add them they equal 180.
Hence, the error is in the statement,
Since the angles are adjacent, they are complementary angles.
Which means when you add them they equal 180.
As, the angles are interior angles on the same side of the transversal.
Also,

A building security code has 2 numeric digits, 0 through 9, followed by 2 letters. What is the probability that the first digit is nine and the last letter is a?.
The probability of the event that the first digit is nine and the last letter is a is 1/260.
The building security code has 2 numeric digits in between 0-9 and 2 letters.
The choices for letters is 26 each and the choices for digits is 10 each.
So, the total possible security code can be,
Total security codes possible = 10 × 10 × 26 × 26
Total security codes possible = 67600
Now, the number of codes that starts with 9 and end with a are,
= 1 × 10 × 26 × 1
= 260
The probability that the first digit is nine and the last letter is a is,
P(E) = 260/67600
P(E) = 1/260

A. x = 4
B. x = 2.14
C. x = 5
D. x = 34.4
Answer: A
Step-by-step explanation: The starting equation is 24 + 0.44x = 19 + 1.69x,
First, combine the x's on the RHS, and the integers on the LHS.
1.69x - 0.44x = 1.25x
24 - 19 = 5
So the equation will be 1.25x = 5
