Answer: {(1, 8.65), (2, 8.30), (3, 7.95)}
EXPLANATION
Given,
The watering can dispenses water at a rate of 0.35 gallon
per minute.
The original volume of water in the can was 9 gallons.
Therefore if,
y = the volume of water in the can in gallons
x = time in minutes
f(x) = y = 9 – 0.35x
When x = 1,
y = 9 – 0.35(1)
y = 9 – 0.35
y = 8.65
Therefore we have the pair (1, 8.65)
When x = 2,
y = 9 – 0.35(2)
y = 9 – 0.7
y = 8.3
Therefore we have the pair (2, 8.30)
When x = 3,
y = 9 – 0.35(3)
y = 9 – 1.05
y = 7.95
Therefore we have the pair (3, 7.95)
The set of ordered pairs shows the volume of water in the
can in gallons (y) as a function of time in minutes (x) from the first minute
after the can starts dispensing water is {(1, 8.65), (2, 8.30), (3, 7.95)}

In the third step, I used the idea that where x is any nonzero number.
From the area of a triangle, the height of the triangle is 12ft
<h3>Area of Triangle</h3>
The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, which is given by
A = 1/2 b * h
- A = Area of triangle
- b = base
- h = height
In the given question, the base is two-thirds of the height.
b = 2/3h
Let's substitute the values into the formula
A = 1/2 * 2/3h * h
A = 2/6 * h²
A = 1/3h²
48 = 1/3h²
h² = 48 * 3
h = √144
h = 12ft

Answer:
two
Step-by-step explanation:
Given:
Number of rows = 3
Number of columns = 6
Number of square boxes = 18
yellow square boxes in the top two rows = 12
Blue square boxes in the first 5 columns = 15
Number of green boxes (shading overlaps) = 10
To find:
The model to show multiplying a fraction by a fraction.
Solution:
2 rows out of 3 are shaded yellow.
Fraction for yellow =
5 columns out of 6 are shaded blue.
Faction for blue =
10 out of 18 squares are green.
Faction for green =
Now,
Therefore, the correct option is D.
