Answer:
The depth of the water in the pool is 2.4 metres
Step-by-step explanation:
The Volume of Water in the Pool= 3000m³
Length of the Pool=50m
Width of the Pool=25m
Height=?
Volume of a Rectangular Prism= Length X Width X Height
3000= 50 X 25 X Height
3000= 1250H
H=3000/1250
Therefore, the Height of water in the pool = 2.4m
The water in the pool is 2.4 metres deep.
(a)

we can see that
curve is moving upward from t=0 to t=4
so, this is increasing interval.........Answer
(b)

we can see that
curve is moving upward from t=15 to t=18
so, this is increasing interval.........Answer
(c)

we can see that
curve is moving downward from t=4 to t=15
so, this is decreasing interval.........Answer
Answer:
71 tadpoles
Step-by-step explanation:
Windstone rescued 54 on Friday.
Let the number rescued on Saturday =x
The number rescued on Friday is 17 less than the number he rescued on Saturday.
This is written as:
To solve for x, we add 17 to both sides of the equation
Windstone Rescued 71 tadpoles on Saturday
I think its 50 because they are half of each others ages so half of 100 is 50 hope it helps sorry if im wrong
Answer:
1) Slope: 3; y-intercept: -7
2) Slope: 2/3; y-intercept: 1
Step-by-step explanation:
y = mx + b; m is slope and b is y-intercept
1. y = 3x - 7
The equation is already in slope-intercept form, so you can find the slope and intercept.
Slope: 3
y-intercept: -7
2. y - 1 = 2/3x
For this one, you have to convert this into slope-intercept form (solving for y)
y - 1 = 2/3x
Add 1 to both sides
y - 1 + 1 = 2/3x + 1
y = 2/3x + 1
Now that the equation is in slope-intercept form, you can get the slope and y-intercept.
Slope: 2/3
y-intercept: 1
