Answer
:Assuming you are talking about odium chloride,NaCl your answer would be
87.7 g
we discover the answer because 1 x 22.99 + 1 x 35.99= 58.4 g/mol
1.50 Moles:
We need to multiply our initial value by 1.50.
1.50 x 58.44/1= 87.66 = 87.7 g

So for number 7, instead of being able to say that the probability is out of 10 because there are 10 cards, you actually need to draw a probability tree and say that the first time you take a card out, the probability of getting an even number is 5/10, but the second time, one card is missing so it is (if the card was an even number first) 4/9 and (if the card was an odd number first) 5/9. Because you want the probability of two even numbers, you would need to say that the first one was even and so was the second, and then you multiply. So, 5/10 × 4/9 = 20/90, which can simplify to 2/9. I hope this helps! Let me know if you need more explanation or anything :)
Answer:
70√2 units²
Step-by-step explanation:
(see attached for reference notes on parallelograms)
we are given ABCD is a parallelogram where
Short Length, AB = 10 units
Long Length, BC = 14 units
Angle A = 45°
The area of the parallelogram is hence,
= AB x BC sin 45°
= 10 x 14 x sin 45
= 140 sin 45° (recall from special angles, that sin 45° = 1/√2)
= 140/√2 (remove radical from denominator by multiplying by √2/√2)
= (140/√2) x (√2/√2)
=70√2 units²
Answer:
y=2x-2
Step-by-step explanation:
in slope intercept form we need make in this formula..
y=Mx+c
Slope-intercept forms:
line r= y= 2/5x+2
line s= y= -3/2x+3
line T= y= -2/3x-2
