Rafael's mortgage payment on his home went up by $117 last month, which represented an increase of 6.5%.
What was Rafael's mortgage payment before the increase?
Answer:
$1800Step-by-step explanation:
Step one:
given data
we are told that Rafael's mortgage payment on his home went up by $117 last month.
let the mortgage payment be x
and $117 is 6.5% of x
6.5/100*x=117
=0.065x=117
Required is the mortgage payment, x
Step two:
divide both sides by 0.065
x=117/0.065
x=$1800
Hence Rafael's mortgage payment before the increase was $1800

Which best describes the relationship between polygon GHJK and polygon G'H'J'K?
A. They are similar because polygon G'H'J'K' can
be obtained from polygon GHJK by a sequence
of transformations.
B. They are similar because the area of polygon
G'H'J'K' is the same as the area of polygon
GHJK.
C. They are NOT similar because polygon
G'H'J'K' cannot be obtained from polygon
GHJK in a single transformation.
KA
D. They are NOT similar because the orientation of
polygon G'H'J'K' is not the same as the
orientation of polyon GHIK
Answer:
1. A. They are similar because polygon G'H'J'K' can be obtained from polygon GHJK by a sequence of transformation
2. B. Reflection across the y-axis
Step-by-step explanation:
1) The coordinates of the sides of the polygon are;
G(-6, 8), H(-2, 4), J(-4, 2), and K(-8, 2)
G'(3, -1), H'(1, -3), J'(2, -4), K'(4, -4)
The length, l, of the sides are;
[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]
Length of GH = √((8 - 4)² + ((-6) - (-2))²) = 4·√2
Length of HJ = √((2 - 4)² + ((-4) - (-2))²) = 2·√2
Length of JK = √((2 - 2)² + ((-4) - (-8))²) = 4
Length of KG = √((2 - 8)² + ((-8) - (-6))²) = 2·√10
Similarly, we have;
Length of G'H' = √(((-3) - (-1))² + (1 - 3)²) = 2·√2
Length of H'J' = √(((-3) - (-4))² + (1 - 2)²) = √2
Length of J'K' = √(((-4) - (-4))² + ((4)- 2)²) = 2
Length of K'G' = √(((-4) - (-1))² + ((4) - 3)²) = √10
Therefore, the polygon G'H'J'K' can be obtained from the polygon GHJK by scaling down by a factor of 2, and the two polygons are similar
2) Given that the coordinates of figure 2 are (-2, 3) (-3, 5), (-4, 1), and (-6, 1), while the corresponding coordinates of figure 3 are (2, 3), (3, 5), (4, 1), and (6, 1) which is equivalent to a transformation from (x, y) to (-x, y) which is the transformation involved in a reflection across the y-axis
Both the polygons are similar because polygon G'H'J'K' can be obtained from polygon GHJK by a sequence of transformations.
Given :
Polygon GHJK and polygon G'H'J'K'.Coordinates -- G(-6,8), H(-2,4), J(-4,2), K(-8,2), G'(3,-1), H'(1,-3), J'(2,-4), and K'(4,-4).The distance formula can be used in order to determine the length of segments of the given polygon.
[tex]\rm GH=\sqrt{(-2+6)^2+(4-8)^2} =\sqrt{32}[/tex]
[tex]\rm HJ=\sqrt{(-4+2)^2+(2-4)^2} =\sqrt{8}[/tex]
[tex]\rm JK=\sqrt{(-8+4)^2+(2-2)^2} =\sqrt{16}=4[/tex]
[tex]\rm GK=\sqrt{(-8+6)^2+(2-8)^2} =\sqrt{40}[/tex]
[tex]\rm G'H'=\sqrt{(1-3)^2+(-3+1)^2} =\sqrt{8}[/tex]
[tex]\rm H'J'=\sqrt{(2-1)^2+(-4+3)^2} =\sqrt{2}[/tex]
[tex]\rm J'K'=\sqrt{(4-2)^2+(-4+4)^2} =\sqrt{4}=2[/tex]
[tex]\rm G'K'=\sqrt{(-4+1)^2+(4-3)^2} =\sqrt{10}[/tex]
Therefore, the correct option is A) They are similar because polygon G'H'J'K' can be obtained from polygon GHJK by a sequence of transformations.

Manuel's heart beats 9 times per 10 seconds while he is resting. How many times would Manuel's heart beat during 3 minutes of rest?
Answer:
The answer is 162
Step-by-step explanation:
For every 60 seconds Manuel's heart will beat 9 times. This means that every minute his heart will beat 54 times. Since he is resting for three minutes we can say that 54x3=162

3g2+ 25g + 8
please put it at (x+b) (x+b) form
Answer:
(3g + 1)(x + 8)
Step-by-step explanation:
3g2+ 25g + 8; think of FOIL
(3g + ___ ) (g + ___); you know you will get the first term when you multiply 3g and g. Also you know that the signs will be positive because 25g and 8 are positive.
Now think of the multiples for 8 because it will be the last term; it could be 4*2 or 8*1 and move the options so you get 25g from outers and inners. You will get this
(3g + 1)(x + 8)

which equation represents the same line as the points in the table
Answer:
[tex]y=\frac{-3}{4} x+2[/tex]
Step-by-step explanation:
First, we can find the slope using the slope equation and two of the points.
Slope equation:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
I'm going to use the first two points just so I can avoid the fraction... Substitute the x and y values into the equation.
[tex]m=\frac{2-5}{0--4}[/tex]
Simplify:
[tex]m=\frac{-3}{4}[/tex]
Now that we have the slope, all we need is the y-intercept. Luckily, it gives it to us in the table. The x value of y-intercepts will always be 0. Looking at the table, we see that the point where x=0 is (0,2). Thus, the y-intercept is 2. Your final equation is
[tex]y=\frac{-3}{4} x+2[/tex]
Answer:
y = -3/4x + 2
Step-by-step explanation:
we will choose any two points: (-4,5) and (0,2)
an linear equation should be like this y=ax+b
a is the slope, b is the y intercept
to find the slope we will use this formula: y1 - y2/x2 - x1
2-5/0-(-4) = -3/4
y = -3/4x + b
now you can find the answers by putting the values of x and y from the table
Kal is making 96 cupcakes for a school event. Each recipe calls for 2 teaspoons of vanilla and makes 24 cupcakes. Kal has only enough vanilla to make 1/4 of the cupcakes he need. How many more teaspoons of vanilla are needed to make all 96 cupcakes.?
Answer:
2 teaspoons of vanilla and it makes 24 cupcakes
Step-by-step explanation:
Heyo!
So, based on what we know, for every 2 teaspoons of vanilla used in the recipe, it is enough to make 24 cupcakes. Kai, however is required to make 96 cupcakes for the school event. This being said, we need to first:
*Multiply 12 by 8:
12 x 8 = 96
Next, you multiply 8 by 2 (2 represents every 24 cupcakes made.
8 x 2 = 16
Hence, he needs a total total of 14 teaspoons of vanilla to add to the vanilla he already has in order to make all 96 cupcakes. Hope this helps!

Step-by-step explanation:
Because two is the variable
Answer:
x = 2
Step-by-step explanation:
Well for starters we know 18 multiplied, or times, x equals 36. So how can we find x? Well you can do the 36 divided by 18, the inverse of multiplication. Then when you do that you get 2. Just to make sure you can substitute 2 for x in the expression and see if it equals 36. And yes it does! Hope this helpss amigo!!
