Answer:
D) Quadrilateral ABCD and quadrilateral A'B'C'D' have the same angle measures.
Step-by-step explanation:
A dilation basically just means that the shape gets proportionately larger (see attached file).
A cannot be true because of the dilation. The shape is now larger than it was by a factor of eight. Therefore the area will not be the same.
B and C are also not true for basically the same reasons. Shape is bigger, therefore the length of the sides are longer and the perimeter is larger.
The only thing that is not affected by a dilation are the shapes angle measures. If those were affected, A'B'C'D' would not be a dilation of ABCD.
Hope this helps.

How do I find the missing sides on this special triangle?
Answer:
x = 6
y = [tex]3\sqrt{2}[/tex]
Step-by-step explanation:
Thats a 45 45 90 triangle, one of my favorite and you'll come to miss it later because of how easy it is.
See the file provided for the trick
Because [tex]3\sqrt{2}[/tex] falls where a 1 is in the diagram that means y is also [tex]3\sqrt{2}[/tex] because you multiply [tex]3\sqrt{2}[/tex] by 1, and to get x you'll multiply the value we're given, [tex]3\sqrt{2}[/tex], by the value in the spot in the given diagram, [tex]\sqrt{2}[/tex].
[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex]
Note; a radical multiplied by itself is the value in the radical
Therefore,
[tex]3\sqrt{2}[/tex] ×[tex]\sqrt{2}[/tex] = 3(2) = 6
Thus x = 6
The explanation for this;
[tex]\sqrt{2}[/tex] * [tex]\sqrt{2}[/tex] = [tex]\sqrt{2}^2[/tex]
And if you square a square root you have its square root times its square root squared, which if it was [tex]\sqrt{4}^2[/tex] it'd ultimately be [tex](2)^2[/tex] which is 2x2 which equals 4
Hope this helps

So first of all you count all the blocks, so it will be 16 blocks (4x4) sideways and horizontal.
A = 16/4 marked blocks = 25%
B = 16/8 marked blocks = 50%
C = 16/6 marked blocks = ?
D = 16/10 marked blocks = 62,5%
So answer would be A

The sales tax rate in New Mexico is 8% You buy an Anime coloring book that is $18. What is the final price of the Anime coloring book? Justify how you determined the final price.
Answer: $ 19.44
Step-by-step explanation:
Give : Original price of coloring book = $18
Sales tax = 8% =0.08 [we divide number by 100 to remove %]
Now , the final price of the Anime coloring book = Original price + (Original price) x (Sales tax)
=$ ( 18+18 x 0.08)
= $ (18)(1+0.08)
= $ (18)(1.08)
= $ 19.44
Hence, the final price of the Anime coloring book = $ 19.44
Mr. Baugh is a car salesman. He is paid a salary of $1800 per month plus $600 for each car that he sells. Find the slope and the y-intercept then write a linear equation that describes the relationship between the number of cars sold x and the monthly salary y. If Mr. Baugh sells 5 cars, how much money will he make for the month?
Answer:
he will make $4800 for that month
Step-by-step explanation:
the slope is 5 passing throught(-1,4)
Answer:
eqn of line
5x-y=-9
Step-by-step explanation:
Answer:
y = 5x + 9
Step-by-step explanation:
Assuming you require the equation.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5 , thus
y = 5x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = - 5 + c ⇒ c = 4 + 5 = 9
y = 5x + 9 ← equation of line

In triangle DEF, segment DJ is a perpendicular bisector of side EF. If EJ is 3y-8 and JF is 7y-40, what is the length of JF?
Answer: The length of JF = 16 units.
Step-by-step explanation:
Given: In triangle DEF, segment DJ is a perpendicular bisector of side EF.
i.e. DJ is perpendicular to EF and DJ divides EF into two equal parts EJ and JF. [The perpendicular bisector is a line that is perpendicular to a line segment and splits it into two congruent segments.]
If EJ is 3y-8 and JF is 7y-40.
Then, [tex]3y-8=7y-40[/tex]
[tex]\Rightarrow\ 7y-3y=40-8\\\\\Rightarrow\ 4y=32\\\\\Rightarrow\ y=8 \text{ [Divide both sides by 4]}[/tex]
JF= 7(8)-40 =56-40= 16 units
Hence, the length of JF = 16 units.

A person can pay $9 for a membership to the history museum and then go to the museum for just $1 per visit. For a member of the history museum, what is the total cost of 23 visits?
Answer:
$32Step-by-step explanation:
Step one:
Given that membership is $9 and the cost per visit is $1
let the number of visits be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that x=23, we can solve for the totals cost as
by substituting we have
y=1*23+9
y=23+9
y=32
The total cost for 23 visits is $32
