Question isnt well formatted :
Answer:
1 : 6
Step-by-step explanation:
Given the question :
3x = 1/2y
3x = y/2
Multiply both sides by 2
3x * 2 = y/2 * 2
6x = y
This can be interpreted as :
y = 6 times the value of x
x = y/6
x : y
37
the formula for this is:
A^2 + B^2 = C^2
if you substitute them:
12^2 + 35^2 =C^2 -> 144+ 1225= 1369
and the square root of 1369 is 37
hope this helps!!!
m<EDC=110
angle c is 35 degrees too, because this is isoceles
using the sum of the triangle's angles which are always 180
70+x=180
x=110
the answer should be 3....this is not right btw
a) -3
b) 117
c) 100
(a) 2(1)²-5(1)
1²= 1
2×1= 2
2-5= -3
(b) 2(9)²-5(9)
9²= 81
81×2= 162
162-45= 117
(c) 2(4)²-5(4) +2(8)²-5(4)
4²=16
16×2= 32
32-20= 12
8²=64
64×2= 128
128-40= 88
88+12= 100
hope it helps!
