Answer:
Using equivalent fractions, the time Matt takes to eat 1 pie is 1200/11 which is the same as [tex]109\frac{1}{11}[/tex] seconds
Step-by-step explanation:
The number of pies Matt eats = 2.75 pies
The time duration Matt eats 2.75 pies = 300 seconds
Mathematically, the time duration for Matt to eat one pie is given as follows;
The time to eat 2.75 pies = 300 seconds
Dividing both sides of the equation by 2.75 gives;
The time to eat 2.75/2.75 pie = 300/2.75 seconds
2.75/2.75 = 1, therefore, we have;
The time to eat 1 pie = 300/2.75 seconds
The equivalent fraction of 3000/2.75 = 1200/11
Therefore;
The time Matt takes to eat 1 pie = 1200/11 seconds
Louis is constructing the perpendicular bisector
of GH . He has already constructed an arc as
shown.
What should Louis do for his next step?
Solution :
It is given that Louis is constructing a perpendicular bisector of a line GH.
Let the line GH be x units of length.
Louis is constructing a perpendicular bisector. So he should follow the following steps :
1. Louis should take the help of a compass and place the needle of the compass on one end of the line and take a measurement that is equal to the more than half the length of the line GH.
2. Then keeping the compass needle at one end of he line, Louis have to draw an arc above and below the line GH.
3. Now with the same measurement in the compass, place the compass needle on the other end and similarly cut two arcs above and below intersecting the previous arcs.
4. Now join the intersecting point with a straight line.
5. This is the perpendicular bisector of the given line GH.

In Algebra you learned that Difference of Perfect Squares is x^2 - 25 = (x+5)(x-5)
Is there a way to factor the sum of perfect squares? ex: x^2 + 25 = (?)(?)
Answer:
(x+5i)(x-5i)
Step-by-step explanation:
We use imaginary numbers to solve that. since i = sqare root of -1 so i * i = -1.

What is the outlier of 29, 2, 28, 30, 26, 31
Answer:
2
Step-by-step explanation:
Given the data : 29, 2, 28, 30, 26, 31
Outlier ;
Lower :Q1 - (1.5 * IQR)
Upper : Q3 + (1.5 * IQR)
Q1 = Lower quartile ; Q3 = upper quartile ; IQR = Interquartile range
Using calculator :
Q1 = 26
Q3 = 30
IQR = (Q3 - Q1) = 30 - 26 = 4
Lower : 26 - (1.5 * 4) = 20
Upper : 30 + (1.5 * 4) = 36
Hence, the number in the given data which falls outside the range is 2

Step-by-step explanation:
Rotation of Figures
When we rotate a figure 90 degrees clockwise across the origin, each point of the given figure has to be changed from (x, y) to (y, -x).
We are given the point (2,1) and it is rotated 90 degrees clockwise across the origin, thus the image has coordinates (1,-2).

Solve the system of linear equations by substitution x-y=2 x+2y=5
Answer:
x = 3
y = 1
Step-by-step explanation:
x - y = 2 ---------------(I)
x + 2y= 5 ----------------(II)
x - y = 2
x = 2 + y _________(III)
Substitute x = 2 + y in equation (II)
2 + y + 2y = 5 {combine like terms}
2 + 3y = 5
3y = 5 -2
3y = 3
y = 3/3
y = 1
Substitute y = 1 in equation (III)
x = 2 + 1
x = 3

The sum of the ages of two friends is 13 years and the product
of their ages is 42. Find their ages.
Step-by-step explanation:
The sum of ages of two friends is 13 years.
The product of their ages is 42.
Let the age of 1st friend and 2nd friend is x, y respectively.
1 st condition= The sum of ages of two friends is 13 yrs.
i.e x+y = 13........ (I)
2nd condition= The product of their ages is 42.
i.e X*y = 42........(ii)
From equation (I)
X+y = 13
or, X = 13-y........ (iii)
Putting the equation (iii) in equation (ii).
X*y= 42
(13-y) * y = 42
13y - y^2 = 42
[tex] {y}^{2} - 13y + 42 = 0[/tex]
[tex] {y}^{2} - (7 + 6)y + 42= 0[/tex]
[tex] {y}^{2} - 7y - 6y + 42 = 0[/tex]
[tex]y(y - 7) - 6(y - 7) = 0[/tex]
[tex](y - 6) (y - 7) = 0[/tex]
Either; y-6 = 0
y = 6
Or;
y-7=0
y = 7
Keeping the value of y as "7" in equation (ii)
x*y = 42
7x = 42
X = 42/7
Therefore, the value of X is 6.
Therefore, either 1st friend is 6 years and 2nd is 7 years.

Answer:
We conclude that:
g(10) = 8Step-by-step explanation:
First, we need to clear some concepts on how to fetch input and output from the function graph.
Determining the y-intercept:
We know that the y-intercept of the graph function can be determined by setting x = 0 and determining the corresponding y-value.
From the graph it is clear that x = 0, the value of y = 5. In other words, the graph intersects the y-axis at y = 5.
Therefore, the y-intercept of the graph is (0, 5).
Thus,
g(0) = 5Determining the x-intercept:
We know that the x-intercept of the graph function can be determined by setting y = 0 and determining the corresponding x-value.
From the graph, it is clear that y = 0, the value of x = -10. In other words, the graph intersects the x-axis at x = -10.
Therefore, the x-intercept of the graph is (-10, 0).
Thus,
g(-10) = 0Determining g(10):
From the graph, it is clearly visible that at x = 10, the value of the function output y = 8.
In other words,
at x = 10, g(10) = 8
Therefore, we conclude that:
g(10) = 8Marta tried solve the system below, but she made a mistake. Read carefully and try to figure out what her mistake was.
Finding Mistakes in a Solution
What was Marta’s mistake? Explain.
Answer:
Marta solved for y in the first equation and then substituted it back into that equation instead of the other one!
Step-by-step explanation:
edge 2020/2021
The mistake Marta did was substituting the value of a variable from equation 1 into same equation itself.
What is System of Equation?The system of equation is set of equations which have a common solution.
Marta was trying to solve the following equations:
10x+y = 22
2x+y =-2
For using the substitution method , the value of a variable is taken in terms of another variable from equation 1 and substituted in equation 2
y = 22 -10x will be substituted in equation 2
2x + (22-10x) = -2
2x +22 -10x = -2
-8x = -24
x = 3
y = -8
The system of equation has finite solution of x = 3, y =-8.

If the plants each cost £3.00
You multiply the amount of plants, in this case is 5 by the price :-
5×3.00
= £15.00
You then subtract the total from the cash

there's a property for Alternate Interior Angles
Answer:
Choice B
Step-by-step explanation:
The reason why < 3 is equal to < 6 is because they are alternate interior angles.
The first choice are supplementary angles they add up to 180 so they can't be equal.
The third one is false because we don't actually know the measurements of the angles but they both need to be 45° to add up to 90 since they are equal to each other.
The last one is also incorrect because they are vertical angles just like the third choice and they aren't on a line so they can't add up to 180.
