Write a congruence statement for the pair of triangles. Name the postulate or theorem that justifies your statement.
Answer:
The answer choice that you have chosen is correct
Step-by-step explanation:
On a coordinate plane, 2 triangles are shown. Triangle F D E is a right triangle and has points (1, 0), (1, 3), and (5, 0). Triangle Q R P is a right triangle and has points (negative 1, negative 2), (negative 1, negative 5), and (negative 5, negative 2). Are ΔDEF and ΔRPQ congruent? Yes. ΔDEF can be mapped to ΔRPQ by a reflection across the x-axis followed by a translation 2 units left. Yes. ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down. No. ΔDEF cannot be mapped to ΔRPQ by a rigid transformation or combination of rigid transformations.
Answer:
Yes
ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down
Step-by-step explanation:
The coordinates of the vertices of the triangles are;
F(1, 0), D(1, 3), and E(5, 0), and Q(-1, -2), R(-1, -5), and P(-5, -2),
Length of FD = √((3 - 0)² + (1 - 1)²) = 3
Length of DE = √((5 - 1)² + (0 - 3)²) = 5
Length of FE = √((5 - 1)² + (0 - 0)²) = 4
For triangle QRP, we have;
Length of QR = √((-5 - (-2))² + (-1 - (-1))²) = 3
Length of RP = √((-5 - (-1))² + (-2 - (-4))²) = 5
Length of PQ = √((-5 - (-1))² + (-2 - (-2))²) = 4
For a reflection across the x-axis, we have;
For a rotation of 180° about the origin, we have;
For a coordinate of the preimage before reflection of (x, y), the coordinates of the image after reflection is (-x, -y)
When followed by a translation 2 units down, we have the coordinates of the image will be (-x, -y-2)
Therefore;
For the points F(1, 0), D(1, 3), and E(5, 0) on triangle FDE, we have;
Rotation 180° about the origin gives;
F(1, 0) → Rotation by 180° → F'(-1, 0)
D(1, 3) → Rotation by 180° → D'(-1, -3)
E(5, 0) → Rotation by 180° → E'(-5, 0)
For a translation 2 unites of the coordinates of the vertices of the above triangle ΔF'D'E',
F'(-1, 0) → Translation 2 units down → F''(-1, -2)
D'(-1, -3) → Translation 2 units down → D''(-1, -5)
E'(-5, 0) → Translation 2 units down → E''(-5, -2)
The coordinates of the vertices of triangle ΔF''D''E'' are equivalent to the coordinates of the ΔQRP
Therefore, ΔDEF, and ΔRPQ are congruent, because ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down.
Answer:
Yes
ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down

C. $1.53
12. What is the total cost for the movie from Target in Summerville (including tax)?

b. $33.30
10cn
Answer:
9. C. $2.00
10. B. $18.00
11. C. $1.53
12. A. $19.53
Step-by-step explanation:
10%, or 1/10th of 20 dollars is 2 dollars.
The movie, therefore, will cost 2 dollars less, or 18 dollars before tax.
To find tax, multiply the total (after price reduction) by the percentage tax (as a decimal, 0.085%), which gives you 1.53.
Add the tax and the initial cost together to get the total cost.
If a frustrated student kicks a wall with 100N force, and does not break, how much force does
the wall respond with?
Answer:
100n back i guess
Step-by-step explanation:
rip kids foot
The force exerted by the wall on the student's foot if the student kicks a wall with 100 N force, is 100 N.
What is force?Force is the influence of either pull or pushes in the body. Basically, gravitation forces, nuclear forces, and friction forces are the types of forces. For e.g. when the wall is hit by a hand then a force is exerted by the hand on the wall as well as the wall also exerts a force on the hand. There are different laws given to Newton to understand force.
Given:
A student kicks a wall with 100 N force,
As we know that every action has an equal and opposite reaction, written in Newton's Law,
Thus, the wall will also exert a force of 100 N on the foot of the student.

slope for (1 -2) (3 3)
Answer:
[tex] \frac{5}{2} [/tex]
Step-by-step explanation:
The formula for slope is (y₂-y₁)/(x₂-x₁)
Which means the (y) from the Second ordered pair subtract (y) from the 1st ordered pair, then divide by (x) from the second ordered pair, minus the (x) from the first.
So (3-(-2))/(3-1)

Which equation represents a line perpendicular to the line whose equation is
6y+5x=48 !!!!!!
Step-by-step explanation:
im putting it in y=mx+b form here
6y+5x=48
subtract 5x on both sides
6y=-5x+48
divide by 6 on both sides
y=(-5x/6)+8
so the slope is -5/6
perpendicular lines have opposite inverse slopes
so
m=6/5
now that you know the slope, hopefully you can find the answer with the same slope, since you didn't provide potential options
A line having the same slope and perpendicular to the line 6y + 5x = 48 is
5y -6x = 40.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
We also know that perpendicular lines have slopes that are negative reciprocals of each other.
Given, 6y + 5x = 48, this in slope-intercept form is,
6y = -5x + 48.
y = (-5/6)x + 8.
Now, the line perpendicular to it has a slope of (6/5) and assuming it has the same y-intercept.
∴ The equation of the perpendicular line is y = (6/5)x = 8.
y - (6/5)x = 8.
5y -6x = 40.

A tree is currently 10 feet tall and grows 2 feet per year. Write an arithmetic sequence in explicit formula that can model this scenario.
Given:
A tree is currently 10 feet tall and grows 2 feet per year.
To find:
The arithmetic sequence in explicit formula that can model this scenario.
Solution:
Current height of tree is 10 feet. So, initial value of the arithmetic sequence is a=10.
It grows 2 feet per year. So, common difference is d=2.
The explicit formula for an arithmetic sequence is
[tex]f(n)=a+(n-1)d[/tex]
where, a is first term and d is common difference.
Put a=10 and d=2 in the above formula.
[tex]f(n)=10+(n-1)2[/tex]
[tex]f(n)=10+2n-2[/tex]
[tex]f(n)=8+2n[/tex]
Therefore, the explicit formula for given scenario is [tex]f(n)=8+2n[/tex].
3. Victoria counts this week's food donations at a pet shelter. There are 16 full cases of canned food. There are 4 cases of canned food that are missing 5 cans. Victoria records a total of 220 cans of food. Use c to represent the number of cans in a full case. What expression could represent the number of cans in each case that is missing cans?
Answer:
We know that C is the total number of cans in a complete case.
Victoria counts:
16 full cases, so in those we have: 16*C cans.
4 cases with 5 missing cans, so in those we have:
Then if each case has C cans, the cases that are missing 5 cans have:
C - 5 cans.
Then in those four cases we have a total of: 4*(C - 5) cans.
And Victoria knows that there are 220 cans, then we have that:
16*C + 4*(C - 5) = 220
16*C + 4*C - 20 = 220
16*C + 4*C = 220 + 20 = 240
20*C = 240
C = 240/20 = 12
Then each case has 12 cans.
Then the number of cans in the cases with missing cans is:
12 cans - 5 cans = 7 cans.
Answer:
16c + 4(c-5) = 220
Step-by-step explanation:
Write the equation of the line with slope 2/3 passing through (6,5) in slope-intercept form.
Answer:
2 = (2/3)*(6)+b
2 = 4+b
b= -2
so slope intercept form is y = (2/3)x -2
To find the point slope form, simply plug in m and the point given.
y-2 = (2/3)*(x-6)

Explanation:
-19=-17+k/5 please show work
Answer:
Step-by-step explanation:
-19=-17+k/5
add 17 to both sides
-2=k/5
multiply by 5 on both sides to get k alone
k=-10
Answer:
okay so if - 19 is equal to 17 + k divided by 5, first you figure out what you have to do to 17 to get -19. in this case, all you do is subtract 17 from 17 to get 0, then subtract 19 from 0 to get -19. then you add 17 and 19 to see how much you subtracted from 17 to get -19, so you subtracted 36 from 17. now you add the - sign to the 36 so that means instead of subtracting a positive number you're adding a negative number (it has the same effect) so you now need to know what, when divided by 5, equals -36. so just multiply -36 by five to get -180. so k = 170
Step-by-step explanation:
-19 = 17 + -180/5
-180/5 is -36
-19 = 17 + -36
17 + -36 = -19
-19 = -19
