Answer:
[tex]A = 4[/tex]
[tex]B = 6[/tex]
Step-by-step explanation:
Let the two sides be A and B, such that:
[tex]A = \frac{2}{3} * B[/tex]
[tex]Perimeter = 20cm[/tex]
Required
Find A and B
The perimeter is calculated as:
[tex]Perimeter = 2 * (A + B)[/tex]
Substitute [tex]\frac{2}{3} * B[/tex] for A and 20 for Perimeter
[tex]20 = 2 * (\frac{2}{3} * B + B)[/tex]
[tex]20 = 2 * (\frac{2B}{3} + B)[/tex]
Divide both sides by 2
[tex]10 = \frac{2B}{3} + B[/tex]
Multiply both sides by 3
[tex]3 * 10 = 3 * (\frac{2B}{3} + B)[/tex]
[tex]30 = 2B + 3B[/tex]
[tex]30 = 5B[/tex]
Solve for B
[tex]B = \frac{30}{5}[/tex]
[tex]B = 6[/tex]
Recall that:
[tex]A = \frac{2}{3} * B[/tex]
[tex]A = \frac{2}{3} * 6[/tex]
[tex]A = 2 * 2[/tex]
[tex]A = 4[/tex]
Hence, the lengths of the sides are 4 cm and 6 cm

Ariel's desk weighs 53 kilograms. What is the weight of her desk in pounds? Round your
answer to the nearest whole number.
* 2.2 pounds is approximately 1 kilogram
Answer:
116.6 pounds
Step-by-step explanation:
Set up a proportion where x is the weight of her desk in pounds:
[tex]\frac{2.2}{1}[/tex] = [tex]\frac{x}{53}[/tex]
Cross multiply:
x = 116.6
So, her desk is 116.6 pounds

Your gym membership costs $10 a month after an initial membership fee of $50. How long have you had your account if you have paid $300? (Hint: Create an equation to model this situation then solve for the unknown.
Answer:
y(300)=10x+50
Step-by-step explanation: we know that Y has to be 300 because that is our final amount of money that we have paid. we pay 10 bucks a month for the membership alone. the initail fee is 50 bucks so what you start with. we then can start plugging in numbers to solve for x. if you do x=25 you will get 300.
10(25)+50=300
250+50=300
therefore your equation will be Y=10x+50

Answer:
The first blank is Reflection across the line x=-3
The second blank is reflection across the line y=x
for Edumentum/PLATO
Step-by-step explanation:
I just did the test. I got it correct. Good luck to everyone else taking their finals rn :)
The complete statement is:
The sequence of transformations that maps [tex]\triangle ABC[/tex] onto [tex]\triangle A'B'C'[/tex] is a
reflection across the line x=-3 followed by a reflection across the line y=x
The coordinates of triangle ABC are:
A= (-4,4), B = (-8,2) and C = (-6,6)
First, the triangle is reflected across the line x = -3.
The rule of this transformation is:
[tex](x,y) \to (|x| - 6,y)[/tex]
When the above transformation is applied to [tex]\triangle ABC[/tex], the coordinates become:
[tex]A = (-2,4)[/tex]
[tex]B = (2,2)[/tex]
[tex]C = (0,6)[/tex]
Next, reflect the above coordinates across the line y = x
The rule of this transformation is:
[tex](x,y) \to (y,x)[/tex]
When the above transformation is applied to [tex]\triangle ABC[/tex], the coordinates become:
[tex]A' = (4,-2)[/tex]
[tex]B' = (2,2)[/tex]
[tex]C' = (6,0)[/tex]
Hence, the sequence of transformations that maps [tex]\triangle ABC[/tex] onto [tex]\triangle A'B'C'[/tex] is a reflection across the line x=-3 followed by a reflection across the line y=x

similar triangles ABE and BCD are shown on the coordinate plane. line t passes through points A, B, and C write equation for t
Answer:
[tex] y = \frac{2}{3}x + 1 [/tex]
Step-by-step explanation:
First, find the slope, m, and y-intercept, b, of line t.
Slope (m) = CD/BD
Slope (m) = 4/6 = ⅔
y-intercept is y = 1. This is where the line intercepts the y-axis. So, b = 1.
Substitute m = ⅔, and b = 1, in [tex] y = mx + b [/tex].
Thus, the equation for line t would be:
[tex] y = \frac{2}{3}x + 1 [/tex]

Find the slope of the line going through the points (6,3) and (1, -22)
Answer:
5
Step-by-step explanation:
The slope is rise over run
The y coordinate moved down 25 units so the rise is -25
The x coordinate moved to the left 2 units, so the run is -2.
In the form of rise over run it will be:
-25/-5 which is equal to 5

Triangle EFG has coordinates E (0, 0), F (0, 2), and G (3, 0). If ΔEFG ≅ ΔXYZ, what is the measure of XY?
pls help
Answer:
2 units
Step-by-step explanation:
Since EFG and XYZ are congruent, we can write it like this:
E = X
F = Y
G = Z
Due to E and F being two units apart on the coordinate plane, we can conclude X and Y are also at a measurement of 2 units! Hope this helps!
Given center C and a point P on a circle, find its equation. C(-2, 7) and P(1, 11)

Answer:
(x +2)² +(y -7)² = 25
Step-by-step explanation:
The length of the radius can be found from the distance formula.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((1-(-2))² +(11 -7)²) = √(3² +4²) = √25
The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
Here, we have (h, k) = (-2, 7) and r = √25, so r² = 25. The circle's equation is ...
(x +2)² +(y -7)² = 25
