Answer:
25 dobles y 42 sencillas
Step-by-step explanation:
25 x 2 = 50 camas + 42 = 92
y 25 habitaciones dobles + 42 sencillas = 67
Answer:
9) a = 8, b = 4√2
10) x = 7√2, y = 7
11) x = 5√2, y = 5
12) a = 10, b = 5√2
Step-by-step explanation:
You can notice all these triangles are special as 45° - 45° - 90° triangles. In 45° - 45° - 90° triangles, the hypotenuse is √2 times the sides. We can set up these equations and solve:
9)
a = 4√2 * √2
a = 8
Since the triangle is isosceles, the legs are the same length, so:
b = 4√2
10)
x = 7 * √2
x = 7√2
Since the triangle is isosceles, the legs are the same length, so:
y = 7
11)
x = 5 * √2
x = 5√2
Since the triangle is isosceles, the legs are the same length, so:
y = 5
12)
a = 5√2 * √2
a = 10
Since the triangle is isosceles, the legs are the same length, so:
b = 5√2
30 60 90 triangle
ratio of short leg : long leg = a : a√3
Given long leg = 9 cm
so
short leg = 9 / √3
= 3√3
= √27
= 27^(1/2) <..........(radical form)
Hope it helps.
Answer:
.767
Step-by-step explanation:
0. ones, tens, hundreds, thousands
L=3W+10 and P=2(L+W)=36
36=2(3W+10+W)
36=8W+20
8W=16
W=2 and since L=3W+10=16
W=2 and L=16
