Answer:
93.75min
Step-by-step explanation:
Solution:
The rate of fill up is, Rate = 3.2 Gallons / minute = 3.2 g/min
The hut tub volume is 300 Gallons
You can set up this problem as follows:
Every 3.2 gallons require 1 minute, How many minutes 300 gallons require?
3.2 g 1min
300 g ? min = (300 gallons x 1min/ 3.2 gallons)=(300/32)min
= 93.75 min
or simply the number minutes is the time required (T) the rate is (R) and the volume is (V)
such that T=V/R= (300g/3.2 g/min)= 93.75 min

X2 + 7x + 10 = 0 has roots -5 and -2, the answer.
How to Find the roots of the equation x2 + 7x + 10 = 0?x2 + 7x + 10 = 0 is a mathematical equation.
x2 + 5x + 2x + 10 = 0 [dividing the middle term] is another way to express the aforementioned equation.
After factoring 2 from the second term of the expression, 2x + 10, and x from the first term of the expression, (x2 + 5x), the expression may be broken down into its constituent parts.
We obtain the factorized equation as follows: x (x + 5) + 2 (x + 5) = 0.
Now we can calculate (x + 2) (x + 5) = 0 by utilizing the distributive property.
The result of separately equating both terms with 0 is,
The equation x2 + 7x + 10 = 0 has -5 and -2 as its roots.

Answer:
9.818 years after 2008
Step-by-step explanation:
Y_A = 0.35 * X + 9.6
Y_B = 0.9 * X + 6.5
Equal in year X = (Y_B - Y_A) / (0.35 - 0.9) = (6.5 - 9.6) / (-0.55) = 9.818 years after 2008
X = 9.818 + 2008 = 2018.818
Y_A = 0.35 * (2018 - 2008) + 9.6 = 14.3 billion
Y_B = 0.9 * (2018 - 2008) + 6.5 = 15.3 billion

Why does it take 3 copies of 1/6 to show the same amount as 1 copy of 1/2? Explain your answer in works and pictures.
Answer:1/6 can be represented as a fraction of a whole unit, where the whole unit is divided into 6 equal parts. Each of these parts represents 1/6 of the whole.
1/2, on the other hand, represents half of the whole unit, so it is twice as much as 1/6.
To visualize this, you can think of a ruler divided into 6 equal parts. 1/6 would represent 1 mark on the ruler, while 1/2 would represent 3 marks. To have the same length as 1/2, you need to add up 3 marks, or 3 copies of 1/6.
You can also think of this as converting 1/6 to a common denominator, which in this case is 6. 3 copies of 1/6 is equal to 3/6 or 1/2.

A certain compound has a half-life of 5 days. Write and use an exponential decay function to find the amount
of compound remaining from a 84-ounce sample after seven weeks.
The amount of compound remaining from a 84-ounce sample after seven weeks is 4.32 ounces.
How to calculate the half life of the substanceGiven a half-life of 5 days and a sample of 84 ounces, the exponential decay function can be represented as:
A(t) = 84 * (1/2)^(t/5)
Where A(t) represents the amount of the compound remaining after t days.
To find the amount of compound remaining after 7 weeks
7 weeks * 7 days/week = 49 days,
we can substitute t = 49 into the function:
A(49) = 84 * (1/2)^(49/5)
A(49) = 84 * (1/2)^9.8
A(49) ≈ 4.32 ounces
So, the amount of the compound remaining after 7 weeks would be approximately 4.32 ounces.

Check all that apply. f(x) > 0 over the interval (−, 3). f(x) ≤ 0 over the interval [0, 2]. f(x) < 0 over the interval (−1, 1). f(x) > 0 over the interval (–2, 0). f(x) ≥ 0 over the interval [2, )
The predicted interval for the given function is, f(x) ≥ 0 over the interval [-1,1]. So Option C is correct
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
The ordered pairs of the given function
(-3,15), (-2,-5), (-1,0), (0,5), and (1,0).
It can be observed from the values of f(x) with respect to x, that the function reaches zero at x = -1, then then reach up to 5 at x = 0 and then again reaches zero at x = 1
Hence, the value of f(x) remains positive within the interval of [-1,1].

Evaluate the like terms
22x = 84
So, we have
x = 3.82
The angles in a triangle add up to 180
So, we have

To solve the expression [(4r²t)³]², you need to follow the order of operations (PEMDAS):
Calculate the expression inside the outermost parenthesis first: (4r²t)³ = (4 * r^2 * t)^3, where r and t are variables.
Raise the result to the power of 3: (4 * r^2 * t)^3 = 64 * r^6 * t^3.
Raise the result to the power of 2: (64 * r^6 * t^3)^2 = 4096 * r^12 * t^6.
