Answer:
The perimeter of EFGH is 30.5
Step-by-step explanation:
figure ABCD is similar to figure EFGH (hence the ~ sign)
A -> B= <u>12</u>
B -> C= <u>12 </u>
C -> D= <u>12</u>
A -> D= <u>25</u>
EFGH has sides that are half of the size of ABCD
there are two ways you can solve this:
A) divide the perimeter of ABCD by 2 (making it half)
61 / 2 = 30.5
or
B) adding all of the sides together
E -> F =6 so therefore so do F-> G and G -> H
6 + 6 + 6 + 12.5 = 30.5
Answer:
z = 110
Step-by-step explanation:
The measure of an angle created by the intersection of two secants outside a circle is half the difference of the angles it intercepts. In this it would be:
2x + 15 = 1/2 * (10x + 20 - 80)
We can now solve:
4x + 30 = 10x - 60
30 = 6x - 60
6x = 90
x = 15
This means the values of 10x + 20 is 10(15) + 20, which is 170.
Now, we can add up all the arcs in a circle, which sum to 360 degrees:
360 = z + 170 + 80
360 = z + 250
z = 110
Answer:
The answer is B
Step-by-step explanation:
If you were to rotate the shape 180* it would turn 2 times leaving the point "H" at (5, -3)
Usando un sistema de ecuaciones, se encuentra que la rapidez inicial del primer ninõ es 4.95 m/s.
-------------------------
- Consideramos que la rapidez inicial de el primer ninõ es x, y de el segundo es y.
El primer niño rebota <u>1.5 veces más alto que el segundo</u>.
O sea:
La rapidez inicial del segundo niño es de 3.3 m/s.
Esto implica que 
¿Cuál es la rapidez (m/s) inicial del primer niño?
La rapidez inicial del primer ninõ es 4.95 m/s.

Answer:
-28/3
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
15-(-13)/-12-(-9)
28/-3 or -9 1/3
Best of Luck!
