Answer:
Option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.
Step-by-step explanation:
Given is the graph of Amount of water (in gallons) v/s Time (in seconds).
It is a linear graph whose general equation is given as follows:-
y=mx+b.
Where y = Amount of water, x = Time, m = slope, b = y-intercept (when time is zero).
Finding slope of line, m = (2.3 - 2.5)/(1 - 0) = -0.2 gallons per second.
Finding y-intercept of line, b = 2.5 gallons (at t=0).
Hence, option B is correct, i.e. The amount of water originally in Wilson's can was 2.5 gallons.

Answer:
kilometers per hour.
Step-by-step explanation:
We have been given an
, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.
We can see that van travel
kilometers in x hours. To find the constant speed of van, we will substitute
in our given equation as:


Since van travels
kilometers in one hour, therefore, constant speed of van is
kilometer per hour or
kilometers per hour.
Answer:
4
Step-by-step explanation:
John caught 18 fishes and Peter caught 30 fishes.
Step-by-step explanation:
Let,
Fishes caught by John = x
Fishes caught by peter = y
Total fishes caught = 48
According to given statement;
x+y=48 Eqn 1
x=
Eqn 2
Putting Eqn 2 in Eqn 1;

Multiplying each term by 5;

Dividing both sides by 8

Putting y=30 in Eqn 1

John caught 18 fishes and Peter caught 30 fishes.
