As it is impossible to understand who have done what ,
the correct construction should be :
You are given point A, point B and point C.
Construct a line parallel to that line AB passing through point C.
1) Place the compass on point B, and swing an arc that crosses line AB and line BC.
Label the points D and E.
2) Keep the compass at the same width, and place it on point C.
3) Swing an arc that crosses line BC, and label the point F outside the segment [BC] .
4) Open the compass to the width between points D and E.
Keeping the compass at the same width, place it on point F.
5) Swing an arc that intersects the arc created from line BC at point C.
6) Mark the intersection of the two arcs as point G.
7) Draw a line through point C and point G.
You just have to discover who has done that.

A grocery store sign indicates that bananas are 3 for $1.50, and a sign by the oranges indicates that they are 5 for $3.00. Find the total cost of buying bananas and 4 oranges.
PLEASE ANSWER THANK YOU
Answers
Answer:
Below
Step-by-step explanation:
1. To find the percentage of a number you would need to multiply it by 0. whatever the percent. In this case we are given the percentage and the tip amount, so we can find the original cost of the ride like this :
2 = 0.2 (x)
Multiply both sides by 10
20 = 2x
Divide both sides by 2
10 = x
The original cost of the ride was $10
2. For this one we already know the cost of the 3 bananas so all we need to find is the cost of 4 oranges
Each orange = $3.00 / 5
= $0.6
For 4 oranges, it would be 0.6 x 4 = $2.4
Adding the price of 4 oranges and 3 bananas together....
2.4 + 1.5 = $3.9
The total cost of buying 3 bananas and 4 oranges is $3.9
Hope that helps! Best of luck <3
What would be the mass of a 10kg suitcase on Neptune?
Answers
The acceleration due to gravity on the surface of the Moon is about 1.625 m/s2. So, an object the mass of 10 kg. will weigh 10 × 1.625 = 16.25 N (newton) on the moon.
The mass will be 16.25 Kg
what is acceleration due to gravity?Acceleration due to gravity is the acceleration gained by an object due to gravitational force. Its SI unit is m/s2. It has both magnitude and direction, hence, it’s a vector quantity. Acceleration due to gravity is represented by g. The standard value of g on the surface of the earth at sea level is 9.8 m/s2.
Gravity is the force with which the earth attracts a body towards its centre. Let us consider two bodies of masses ma and mb. Under the application of equal forces on two bodies, the force in terms of mass is given by:
mb = ma [aA/aB] this is called an inertial mass of a body.
Given:
mass of object = 10 kg
Acceleration due to gravity on Moon
=1.625 m/s²
So,
Mass of object on moon= 1.625 * 10 = 16.25 Kg

Shreya has a photo that is 16 cm tall and 20 cm wide. She wants to put a frame around the photo which would have the same width all around.
Represent the area of the whole frame as a polynomial in terms of the width around the photo.
A.[tex]x^{2} + 36x + 320[/tex]
B.[tex]-4x^{2} - 72x + 320[/tex]
C.[tex]4x^{2} + 72x + 320[/tex]
D.[tex]-x^{2} - 36x - 320[/tex]
Answers
A photo is usually rectangular in shape. This means that if a frame is to be put around the photo with the same width all round, it means that if the width is "x", then the new length and width will be (l + 2x) and (w + 2x) respectively where l is length and w is width.
Option C is the correct answer
Data Given;
Height of Photo: 16 cm
Width of Photo: 20 cm
Since she wants to put a frame with same width around the photo, let's represent this width as x.
Thus;
New height = 16 + 2x
New width = 20 + 2x
Area of a rectangle is given as:
A = Length * width
Thus, in this case;
A = (16 + 2x) × (20 + 2x)
Multiplying out, we have;
A = [tex]4x^{2} + 32x + 40x + 320[/tex]
A = 4[tex]x^{2} + 72x + 320[/tex]
Looking at the given options, Option C is the correct answer

Answer: The greatest number of students for whom 30 apples, 45 pears and 60 oranges can be distributed equally is 15.
Step-by-step explanation:
taking HCF
so
HCF of 30,45,60
30 = 2*5*3
45 = 3*3*5
60=3*2*2*5
HCF = 3*5 = 15
so
1 student will get = 30/15 = 2 apples
1 student will get = 45/15 = 3 pears
1 student will get = 60/15 = 4 oranges

Write the equations using point slope form. Then put into slope intercept form. (3,-4), m=2 and (-5,1), m=4/3
Answers
Answer:
Y= 2x + 10
Y= 4/3 x + 7 2/3
For the first equation with points (3,-4) and m there are three values that we can plug into the equation y=mx + b to find the missing value in this situation, the y-intercept.
First, write the equation with the given values and you should have something like this:
-4 = 2(3) +b
The only value that hasn't been discovered yet is b so we solve the equation appropriately to get our value.
-4 = 6+ b
-10= b
And now that we know that the value of b is -10 we can plug -10 into the equation and get the equation Y= 2x + 10
Now for the second, we complete the same steps. We know that we have the points and the slope and subsequently plug it into the equation and receive our answer( for the y-intercept).
1= -5(4/3) +b
1= - 6 2/3 + b
7 2/3 = b
Once we see that the value of b is 7 2/3 we plug it into the equation and get Y= 4/3x + 7 2/3
