Part B
Answers
the 4 ordered pairs for the given proportional relation are (1, 7), (2, 14), (3, 21), (4, 28).
How to find the set of ordered pairs?
Here we know that the sloth travels about 7 feet every minute, then we can define the speed as:
S = 7 ft/min
Now remember the relation:
distance = speed*time
Then the proportional relation is:
D = 7*t
The ordered pairs are of the form (t, D)
if t = 1.
D = 7*1 = 7
if t = 2
D = 7*2 = 14
if t = 3
D = 7*3 = 21
if t = 4
D = 7*4 = 28
Then the 4 ordered pairs are (1, 7), (2, 14), (3, 21), (4, 28).

Parvinder wants to save $500 for a trip. Which inequality shows the least amount she must save each month for 6 months to accomplish this?
A 6x 500 B 6x > 500 C 6x => 500 D x => 500 + 6
Answers
Answer:
The correct answer is C. 6x = 500.
Step-by-step explanation:
In this expression, the "x" represents how many dollars he needs to save every month. Or in other words, the amount of money he earns a month multiplied by the amount of months should equal 500 in order for Parvinder to be able to go on his trip.
Therefore, the correct answer is C. 6x = 500.

Which ordered pair is a solution of the equation y=5x? (-2, 10) (-5, 25) (-3, 15) (-2, 10)
Answers
One of the solutions of the given equation y = 5x is (2,10)
The solution of an equation means if we substitute the value of this solution into the equation, it will produce the correct equality from the left side to the right side.
If the solution has 2 variables, for example x and y, and the solution is (a,b) means that if we replace x with a and y with b, the equality is correct.
The given equation is: y = 5x
For option (-2,10), substitute x = -2 and y = 10 into the equation:
10 = 5 . (-2)
10 = -10 (False)
Hence (-2,10) is not a solution.
For option (-5, 25), substitute x = -5 and y = 25 into the equation:
25 = 5 . (-5)
25 = -25 (False)
Hence (-5, 25) is not a solution.
For option (-3, 15), substitute x = -3 and y = 15 into the equation:
15 = 5 . (-3)
15 = -15 (False)
Hence (-3, 15) is not a solution.
There is no options in the problem that gives the correct equality. Looks like there is a typo.
Example of a solution of the given equation is (2,10), since if we substitute x = 2 and y = 10 into the equation:
10 = 5 . (2)
10 = 10 (True)
Hence (2, 10) is a solution.

the midpoint of AB is M (4,0). if the coordinates of A are (3, 1), what are the coordinates of B?
Answers
The coordinates of point B are (5, -1) if the midpoint of AB is M(4, 0) and the coordinates of A are (3, 1).
Let the coordinates of point B are (x, y).
According to the give question.
The midpoint of AB is M(4, 0).
The coordinates of A are (3, 1).
Therefore, the coordinates of points B are given by
(4, 0) = ( (3 + x)/2, (1 + y)/2)
⇒ (3 + x)/2 = 4, and (1 + y)/2 = 0
⇒ 3 + x = 8 and 1 + y = 0
⇒ x = 8 - 3 and y = -1
⇒ x = 5 and y = -1
Hence, the coordinates of point B are (5, -1) if the midpoint of AB is M(4, 0) and the coordinates of A are (3, 1).

Use the definition of congruence to decide whether the two figures are congruent
Someone help please
Answers
Answer:
These two figures are not congruent.
Step-by-step explanation:
The definition of congruence is, "In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.", now knowing this we next take a look at the figures.
Coordinates (A, E) do not match up with the bottom figures (P, T). The next coordinates (E, D) also don't match up with coordinates (T, S). Coordinates (A, B) and (P, Q) don't match up together either. (B, O), (Q, R), (O, D), or (R, S) also do not match up if you look closely at them. Now you can conclude that although these two figures may look alike at first glance, their points are put in different places showing that they aren't the same in shape and size; meaning they are not congruent.
Two figures are congruent if their dimensions are equal
ABCDE = PQRST therefore, ABCDE ≅ PQRST, by the definition of congruency
Reason:
The coordinates of pentagon ABCDE are;
A(-2, 8), E(4, 8), D(6, 2), C(-2, 2), B(-4, 6)
The coordinates of pentagon PQRST are;
P(-3, 0), T(3, 0), S(5, -6), R(-3, -6), Q(-5, -2)
By performing the vector translation of [tex]\dbinom {1}{8}[/tex], to PQRST, we have;
P(-3 + 1, 0 + 8) = (-2, 8) = Coordinates of A
T(3 + 1, 0 + 8) = (4, 8) = Coordinates of E
S(5 + 1, -6 + 8) = (6, 2) = = Coordinates of D
R(-3 + 1, -6 + 8) = (-2, 2) = = Coordinates of C
Q(-5 + 1, -2 + 8) = (-4, 6) = = Coordinates of B
Given that a translation is a rigid transformation and that by performing a translation transformation of [tex]\dbinom {1}{8}[/tex], on PQRST gives ABCDE, we have that the dimensions of the pentagon ABCDE = The dimensions of the pentagon PQRST, we have;
ABCDE = PQRST

To solve, you must use the Triangle Inequality Rule -
Subtract 7-4=3; therefore, the 3rd side must be greater than 3
Add 7+4=11; therefore, the 3rd side must also be less than 11

Answers
Answer: 17.28 cm^2
Step-by-step explanation:
You can also use AC as the base, then BE will be the height to that.
Assuming you want your answer in cm^2, then (7.2*4.8)/2 = 17.28 cm^2.
Answer:
2160mm
Step-by-step explanation:
Recall that to find the area of a triangle, you need to follow the formula:
A = 1/2 * b * h
But first we need to convert the cm to mm, or else our calculations will be incorrect:
9.6 cm = 96 mm
4.8 cm = 48 mm
Let's cut the triangle into two pieces to make it easier for us to find the area. We'll start with triangle ACD:
A = 1/2 * 36 * 72
A = 1/2 * 2592
A = 1296 mm
Now that we have the area for triangle ACD, let's move on to try to find the area of triangle DCB:
A = 1/2 * 36 * 48
A = 1/2 * 1728
A = 864
It's time to add them up:
(DCB) 864 + (ACD) 1296 = 2160
The area of the triangle is 2160 mm.
