Answer:
14/27 feet
Step-by-step explanation:
2 1/3 feet : 4 1/2 feet
= 7/3 : 9/2
= 7/3 ÷ 9/2
= 7/3 × 2/9
= (7*2)/(3*9)
= 14/27 feet
2 1/3 feet : 4 1/2 feet = 14/27 feet
X^2+2x+3+2(x^2+2x+3)+3+4(x^2+2x+3)+6+8(x^2+2x+3)+9+16(<span>x^2+2x+3)+12
add that up and you will get your answer and you get </span><span>31x²+62x+123</span>
If n is the first of these integers, then the other three are n + 1, n + 2, and n + 3. Then
n + (n + 1) + (n + 2) + (n + 3) = 114
4n + 6 = 114
4n = 108
n = 27
So the four numbers are 27, 28, 29, and 30.
For every person that walked there were 12 who drove and if the 270 made the trip then 87 walked
Answer:
1120 grams
Step-by-step explanation:
The amount of sea water is directly proportional to the amount of salt in the water.
Let the amount of sea water be W and the amount of salt be S.
This means that:
W α S
=> W = kS
where k = constant of proportionality
2 liters of sea water contain 70 grams of salt Therefore:
2 = k * 70
k = 2 / 70 = 1/35
Therefore, for 32 liters of sea water:
32 = 1/35 * S
S = 35 * 32
S = 1120 grams
There are 1120 grams of salt in 32 liters of water.
