30/12 in simplest form is 5/2 (cause 6 * 5 = 30 and 6 * 2 = 12)
40/16 in simplest form is 5/2 (cause 8 * 2 = 16 and 8 * 5 =40)
so yes they're equivalent;
30/12 = 40/16
Hope that helps :D have a nice day!
When you decrease 20 to 11,the decrease is 9
the percentage decrease is
(9/20)*100
=9*100/20
=9*5
=45%

Hmm im not sure
Step-by-step explanation:
Answer:
0.5532
Step-by-step explanation:
P( 31<X<35.7)
P(X>31)= P(Z>(31-μ)/σ)
= P(Z>(31-34.6)/2.8)
= P(Z> -1.2857)
P(X<35.7)= P(Z<(35.7-μ)/σ)
= P(Z<(35.7-34.6)/2.8)
=P(Z< 0.392857)
From z-distribution table
P(Z< -1.29)= 0.09853
p(Z< 0.39) = 0.65173
P( 31<X<35.7)= P(Z<0.39)- P(Z<-1.29)
= 0.65173- 0.09853
=0.5532
Answer:
B
Step-by-step explanation:
X = 29 by the alternate interior angles
y = 49 by the triangle sum theorem
z = 102 because the opposite sides of a parallelogram are congruent
