A large koi pond is filled from a garden hose at the rate of 12 gal/min. Initially, the pond contains 200 gal of water.
(a) Find a linear function V that models the volume of water in the pond at any time t.
(b) If the pond has a capacity of 1304 gal, how long does it take to completely fill the pond?
a) The linear function that models the amount of water after t minutes is given by:
[tex]V(t) = 200 + 12t[/tex]
b) It takes 92 minutes to completely fill the pond.
Item a:
Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.Then, the function is:
[tex]V(t) = 200 + 12t[/tex]
Item b:
It takes t minutes to fill the pond, t is found for which:
[tex]V(t) = 1304[/tex]
Then
[tex]200 + 12t = 1304[/tex]
[tex]12t = 1104[/tex]
[tex]t = \frac{1104}{12}[/tex]
[tex]t = 92[/tex]
It takes 92 minutes to completely fill the pond.

Answer:
[tex]x>-5[/tex]
Step-by-step explanation:
[tex]\frac{-1}{5} x+1<2[/tex]
Subtract 1 from both sides
[tex]\frac{-1}{5} x+1-1<2-1[/tex]
Simplify
[tex]\frac{-1}{5} x<1[/tex]
Multiply both sides by -1, which reverses the inequality also

5. Gardener Gary planted 21 rows of tomatoes
and squash. He planted twice as many rows of
tomatoes as rows of squash. How many tomato
plants were planted if there are 12 plants per
row?
Answer:
168
Step-by-step explanation:
first find out how many rows of squash there are
21 = x + 2x
21 = 3x
7 = x
then find out how many rows of tomatoes there are
7 × 2 = 14
if there are 12 plants per row, we can multiply
14 × 12 = 168
Gardener Gary planted 168 tomato plants
How to determine the number of yellow leaves?Let the rows of tomato be x and the rows of squash be y.
So, we have:
x + y = 21
The statement twice as many rows of tomatoes as rows of squash means that:
x = 2y
Substitute x = 2y in x + y = 21
2y + y = 21
This gives
3y = 21
Divide by 3
y = 7
Substitute y = 7 in x = 2y
x = 2 * 7
x = 14
This means that Gary planted 14 rows of tomato.
The number of tomato plants is then calculated using
Tomato plants= 14 * plants per row
This gives
Tomato plants = 14 * 12
Evaluate the product
Tomato plants = 168
Hence, Gardener Gary planted 168 tomato plants

if f(x)=3x-1 and g(x)=x+2,find (f+g)(x)
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
Given f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x):
We can rewrite (f + g)(x) as f(x) + g(x), and solve the composite functions through addition:
f(x) + g(x) = (3x - 1) + (x + 2)
Combine like terms:
f(x) + g(x) = 3x + x + 2 - 1 = 4x + 1
Therefore, (f + g)(x) = 4x + 1.

Which number equals 3/4 to the power of negative 2?
What exactly is this? 2+6x = 1-x
Answer Please !!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
I can't draw here, but I can describe :
an isoceles triangle means that 2 sides of the triangle are equally long (they are typically called the "legs" left and right on top of the baseline).
this fact makes the triangle symmetrical.
and that means that 2 angles are also equal (the angles of the legs with the baseline).
so, knowing that one angle is 34 degrees can mean 2 things :
either 34 degrees is the angle between the 2 legs, or it is one of the 2 equal angles between legs and baseline.
as we know the sum of all angles in a triangle is always 180 degrees.
so case 1 : 34 degrees is the angle between the legs
180 = 34 + 2×base-leg-angle
144 = 2×base-leg-angle
each base-leg-angle = 72 degrees
case 2 : 34 degrees is one of the base-leg-angles
180 = 2×34 + between-the-legs-angle
180 = 68 + between-the-legs-angle
between-the-legs-angle = 112 degrees
so, you need to draw one triangle for each case.
since we don't know anything about the side lengths, size does not matter. only the angles need to be correct :
one triangle with 34, 72, 72 degrees
and one triangular with 34, 34, 112 degrees

What is the rule when you add a negative number and positive number?
Answer:
a negative plus positive equals a negative-
Answer:
"To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero."
Step-by-step explanation:
Simpler Explanation: If you add a positive number with a negative number, the sign (negative/positive) of the sum is the same as the integer (number) with the largest absolute value. For example;
1. 10 + -12 = -2
Here, the sum has the same sign (negative) as the largest number in the equation (-12).
2. 7 + -3 = 4
Here, the sum has the sign (positive) as the largest number in the equation (7).
The larger of two numbers is 15 more than three times the smaller number. If the sum of the two numbers is 63, find the numbers.
Answer:
Let x = the smaller number
Let 3x + 15 = the larger number
x + 3x + 15 = 63
4x = 48
x = 12
3(12) + 15 = 51

Answer:
The midpoint is (-1, 1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, average the x coordinates of the endpoints
(2+-4)/2 = -2/2 = -1
To find the y coordinate of the midpoint, average the y coordinates of the endpoints
(-3+6)/2 = 3/2 = 1.5
The midpoint is (-1, 1.5)
