A barrel contained 70 gallons of water. Water leaked out of the barrel at a rate of 5 gallons every 3 days.
At this rate, how many days did it take for all 70 gallons of water to leak out of the barrel?
Answer:
42 days
Step-by-step explanation:
Given
[tex]Gallons = 70[/tex]
Leakage = 5 gallons in 3 days
Required
Determine the number of days it finish leaking out
The scenario can be represented as:
5 gallons = 3 days
and
70 gallons = x
Where x represents the number of days to leak out 70 gallons
Cross Multiply:
[tex]5 * x = 3 * 70[/tex]
[tex]5 x = 210[/tex]
Divide both sides by 5
[tex]x = \frac{210}{5}[/tex]
[tex]x = 42[/tex]
Hence, it'll take 42 days

Jonathon is [y/x] years older than Jean.
How does a straight line represents the proportionality ratio?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written to express proportional relationship as -
y = kx {k is constant}
We have Jean is [x] years old and Jonathan is [y] years old
Assume that Jonathon is [m] years older than Jean. Then we can write -
y = mx
or
m = y/x
Therefore, Jonathon is [y/x] years older than Jean.

Answer:
i think 20 is above 12 and 17 under 30 and 36 is on top of 20 the rule is .50(x) +2
Answer:
Step-by-step explanation:
c = 0.5t + 2
12 = 0.5t + 2 ⇒ 0.5t = 10 ⇒ t = 20
c = 0.5(30) + 2 ⇒ c = 17
20 = 0.5t + 2 ⇒ 0.5t = 18 ⇒ t = 36

Complete question is;
A family of 6 is visiting a mall. The mall has 10 exit doors. Assume random selection. Find the probability that
a. No family member chooses the same exit door.
b. Every family member chooses the same exit door.
Answer:
A) 0.6
B) 0.1
Step-by-step explanation:
A) We are told there are 10 exit doors and the family consists of 6 people.
This implies that for them not to choose the same exit door there will be 6 different doors they will pass.
Thus;
Probability that the no family member chooses the same exit door = 6/10 = 0.6
B) If they all choose the same exit door, it means only 1 out of the 10 exit doors will be used by them.
Thus;
Probability that every family member chooses the same exit door = 1/10 = 0.1
