Answer: h=(D²-s)/3
Step-by-step explanation: D² =3h+s
Subtract a from both sides of the equation
D²-s =3h+s-s
Simplifying,
D²-s =3h
Divide both sides by 3( to isolate 'h')
(D²-s)/3 =3h/3
Simplifying,
(D²-s)/3 =h
Hence, h= (D²-s)/3
Hope it helps!
Answer:
<u>1. The theoretical probability of rolling an even number and flipping heads is 25%.</u>
<u>2. The experimental probability of rolling a 1 and flipping tails is 15%.</u>
<u>3. The experimental probability of flipping heads is 40%.</u>
<u>4. I think around 7%.</u>
<u>5. I would expect to roll 3 and land on heads 8 times.</u>

Answer:
One piece is 
inches and another piece is 
inches
Step-by-step explanation:
Let smaller piece length be 
Let larger piece length be 
Since total of two pieces is 43, we can write:
Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:
<em>Substituting equation 2 into equation one, we can solve for s:</em>
<em>Thus longer piece is:</em>
Let the two numbers be x and y.
x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________
2x = 98
x = 98/2
x = 49
From x + y = 86
49 + y = 86
y = 86 - 49
y = 37
The numbers are 49 and 37.
Answer:
hello : x = (ln(20))/3
Step-by-step explanation:
4 + e3x = 24?
e3x = 24 - 4
e3x = 20
3x = ln(20)
x = (ln(20))/3
