Answer:
700 mL
Step-by-step explanation:
You want to know the whole amount if 8% of it is 56 mL.
RelationThe problem statement tells you ...
8% × whole = 56 mL
Divide by the coefficient ...
whole = (56 mL)/(0.08) = 700 mL
The whole amount is 700 mL.

What is an equation ?According to algebra, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 4x + 5 = 15 consists of the two equations 4x + 5 and 15, which are separated by the 'equal' sign.
According to the given information
X + Y + Z = 2000000
0.07X + 0.085Y + 0.095Z = 157000
Y = 4Z
Y = 4Z is substituted into the first and second equations as follows:
X + 5Z = 2000000
0.07X + 0.085 (4Z) + 0.095Z = 157000
X = 2000000 - 5Z
0.07X + 0.435Z = 157000
0.07 (2000000 - 5Z) + 0.435Z = 157000
140000 - 0.35Z + 0.435Z = 157000
0.085Z + 140000 = 157000
0.085Z = 17000
Z = 200000
Y = 800000
X = 1000000

Which equation choice could represent the graph shown below?
The function representing the graph is f(x) = (x + 5)²(x - 3)². The correct option is (a).
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The given graph of the function cuts x axis at (-5,0) and (3,0) and y axis at (0,225) respectively.
Since the zeros of a function is the point at which it cuts the x-axis, the zeros at of the given functions are -5 and 3.
Which implies that the factors are (x + 5) and (x - 3) respectively.
The given factors are valid for options (a) and (d).
Now, at x = 0 f(x) should be 225.
It can be checked for both the options as follows,
(a) f(x) = (x + 5)²(x - 3)²
=> f(0) = (0 + 5)²(0 - 3)²
= 5² × -3²
= 225
Hence, the function that represents the given graph is f(x) = (x + 5)²(x - 3)².

The data are represented by the exponential function f(x) = 2x, where x is the length. Explain how he can convert this equation to a logarithmic function when strength is 8 Pascals.
x = ㏑₂8 in the logarithmic function.
What is a logarithmic function?A logarithmic function is the inverse of an exponential function.
Given function if f(x) = [tex]2^{x}[/tex],
When strength is equal to 8 pascals, f(x) = 8
Therefore, 8 = [tex]2^{x}[/tex]
Taking log on both sides:
ln8 = ln[tex]2^{x}[/tex]
ln8 = xln2
or x = ln8/ln2

The radius of a circle is increasing at a constant rate of 7 centimeters per minute. At the instant when the radius of the circle is 88 centimeters, what is the rate of change of the area? Round your answer to three decimal places.
The rate of change of the area is 3868.48 cm2/min
What in math is a rate?
A rate is a unique ratio where the two words are expressed in several units. For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. This ratio compares two dissimilar units: ounces and cents
A = A(r) (r)
r = r(t) (t)
A = A(r(t))
The chain rule can be used to resolve this kind of issue.
Rate of area change:
(dA/dr)(dr/dt) = dA/dt
A=r2 dA/dr = 2r
dr/dt [given] = 7 cm/min
(2r)(7 cm/min) = (dA/dt)
If r = 88 cm,
dA/dt = 2π (88 cm) (7 cm/min) ≅ 3868.48 cm2/min
