Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = 
, then
sin45° = 
= 
= ( cross- multiply )
s × 
= 
( divide both sides by )
s = 
= 
= 
= 4 → D

52 cards in a deck
4 suits
1/4 of 52 are hearts
1/4 of 52=13 cards
probability of getting 1 heart at first is 1/4
one card is taken out and assuming that it is the heart, 13-1=12,52-1=51
12/51
multiply
1/4 times 12/51=3/51=1/17
Answer:
−4.6p−6.3p+3.9=−9.18
−4.6p+−6.3p+3.9=−9.18
(−4.6p+−6.3p)+(3.9)=−9.18(Combine Like Terms)
−10.9p+3.9=−9.18
−10.9p+3.9=−9.18
Step 2: Subtract 3.9 from both sides.
−10.9p+3.9−3.9=−9.18−3.9
−10.9p=−13.08
Step 3: Divide both sides by -10.9.
−10.9p
−10.9
=
−13.08
−10.9
p=1.2
Answer:
x = (r-b) /a
Step-by-step explanation:
ax + b = r
Subtract b from each side
ax+b-b = r-b
ax = r-b
Divide each side by a
ax/a = ( r-b)/a
x = (r-b) /a
