Select all that apply: 21 days is equal to... Question 6 options: 504 hours 30,240 minutes 1081404 seconds 3 weeks 1 month
by using the operation of multiplication, we get that 21 days is equal to 3 weeks, 504 hours, 30240 minutes and 1,814,400 seconds.
We are given the total number of days as 21.
Now, we know that:
In 1 week, we have 7 days.
So, in 3 weeks = 7 × 3 = 21 days.
Also, 1 day has = 24 hours.
So, by using multiplication, we get that:
21 days = 24 × 21 hours
= 504 hours
Also,
1 hour = 60 minutes
504 hours will be calculated again by using multiplication.
504 hours = 504 × 60 = 30240 minutes
30240 hours = 1,814,400 seconds.
Therefore, by using the operation of multiplication, we get that 21 days is equal to 3 weeks, 504 hours, 30240 minutes and 1,814,400 seconds.

Hannah painted a 50 square foot wall in her home. The graph shows the remaining Square feet to paint as a linear function of X, The number of minutes spent painting. what is the domain and range of the function?
Answer:
Domain: 0 ≤ x ≤ 25
Range: 0 ≤ y ≤ 50 where y = f(x)
Step-by-step explanation:
Domain is the set of all x values. Here x is the number of minutes spent painting and we can see its minimum value is y=0, maximum value is y=25 os domain of function is 0 ≤ x ≤ 25
Range of a function is the set of values of the function ie the outputs produced the function.
Let y = f(x) Then the y values range from minimum of y = 0 to maximum of y = 50. So range is 0 ≤ y ≤ 50 which is 0 ≤ y ≤ 50

Write each expression in simplest form. (x¹/₃/y⁻³/₃)⁹
The simplest form of the expression [tex](\frac{x^{\frac{1}{3} }}{y^{\frac{-3}{3} }} )^{9}[/tex] is yx³.
The simplest form of a fraction is one with a reasonably prime denominator and numerator. It indicates that, except for 1, there is no common factor between the fraction's numerator (upper portion or top) and denominator (lower part or bottom).
A fraction is a number that has been expressed as a quotient by dividing the numerator by the denominator. Both are integers in a simple fraction. In a complex fraction, a fraction can be found in either the numerator or the denominator.
An expression is made up of a number, a variable, or a combination of a number, a variable, and operation symbols. Two expressions joined by an equal sign form an equation.
Consider the expression,
[tex](\frac{x^{\frac{1}{3} }}{y^{\frac{-3}{3} }} )^{9}[/tex]
[tex](\frac{x^{\frac{1}{3} }}{y^{\frac{-3}{3} }} )^{9}=\frac{x^{\frac{1}{3} }}{y^{-1}}[/tex]
We know, x⁻¹ = 1/x
[tex](\frac{x^{\frac{1}{3} }}{y^{\frac{-3}{3} }} )^{9}=(yx^{\frac{1}{3} })^{9}[/tex]

The length is 50. You solve it by making an equation out of the information given. the rectangle's length(l) is 3 times its width(w) and its perimeter(p) is 128. So in order to solve this you need an equation to find the perimeter, isolating w to find l. It'll look something like this:
(3w+8)+(3w+8)+w+w=128
?You combine all like terms turning it into:
2(4w+8)=128
8w+16=128
8w=112
w=14
you use the value of w to solve for l as follows:
l=w*3+8
l=14*3+8
l=42+8
l=50

The partial derivatives for this problem are given as follows:
[tex]\frac{\partial z}{\partial x} = -\frac{x}{\sqrt{\frac{1 - x^2 - 4y^2}{7}}}[/tex][tex]\frac{\partial z}{\partial y} = -\frac{4y}{\sqrt{\frac{1 - x^2 - 4y^2}{7}}}[/tex]How to find the partial derivatives of a function?To find the partial derivatives of a function, we apply the same rules that we apply for complete derivatives, just considering the variables for which we are not deriving the function as constants.
For this problem, the function is given as follows:
x² + 4y² + 7z² = 1.
The function for z is given by:
7z² = 1 - x² - 4y²
[tex]z = \sqrt{\frac{1 - x^2 - 4y^2}{7}}[/tex]
As a function of x, the derivative will be given by:
[tex]\frac{\partial z}{\partial x} = -\frac{x}{\sqrt{\frac{1 - x^2 - 4y^2}{7}}}[/tex]
Because the derivative of the inside term as a function of x is of -2x, then we apply the derivative of the root and simplify -2 with 2.
For the derivative as a function of y, we follow the same procedure, with the lone difference being the the inside derivative is of -8y, then:
[tex]\frac{\partial z}{\partial y} = -\frac{4y}{\sqrt{\frac{1 - x^2 - 4y^2}{7}}}[/tex]

2 μm
2 nm
2 mm
Which is bigger ? And which is smaller?
The bigger measurement is 2 mm and the smaller measurement is
2 μm.
Given, the measurements are :
2 μm
we know that to convert from micro meter to meter, we use:
1 μm = 0.01 meter.
2 μm = 2 × 0.01 m
2 μm = 0.02 m
2 μm = 2/100
2 μm = 2 × 10⁻² m
for 2 nm
we know that to convert from nano meter to meter, we use:
1 nm = 10⁻⁹ meters.
2 nm = 2 × 10⁻⁹ meters.
for 2 mm
we know that to convert from milli meter to meter, we use:
1 mm = 0.001 meters.
2 mm = 2 × 0.001 m
2 mm = 0.002 m
2 mm = 2/1000 m
2 mm = 2 × 10⁻³ m
therefore , 2 × 10⁻² m > 2 × 10⁻³ m > 2 × 10⁻⁹ m
we can notice that millimeter is the greatest and nanometer is the smallest.
Hence we get the greater and smaller measurements.

The missing terms in the given factorized expression are:
3x²y + 12xy² + 9xy = 3xy ( x + 4y + 3 )
What is an expression?An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.
We have,
_ x²y + _ y² + 9 _ = 3x _ ( _ + 4y + _ )
We need to fill the boxes and make sure that both sides are equal.
We will remove the bracket on the right side.
i.e 3x _ _ + 12xy_ + 3x_ _
Now,
_ x²y + _ y² + 9 _ = 3x _ _ + 12xy_ + 3x_ _
We will make,
_ x²y and 3x _ _ equal.
_ y² and 12xy_ equal.
9 _ and + 3x_ _ equal.
So,
(3)x²y = 3x (x)(y)
(12x)y² = 12xy(y)
9 (xy) = 3x(y)(3)
Thus the missing terms in the given factorized expression are:
3x²y + 12xy² + 9xy = 3xy ( x + 4y + 3 )
3x²y + 12xy² + 9xy = 3x²y + 12xy² + 9xy

A circle has a mass of 6 grams and a square has a mass of 3 grams. Which is the mass
of a triangle?
Solve each equation. Show your work.
The mass of the triangle from the hanger diagram is found as 5 grams.
What is termed as the equilibrium of masses?When all of the forces acting on the object are balanced, the object is said to be in equilibrium. If the rightward forces are balanced by that of the leftward forces as well as the upward forces are balanced by that of the downward forces, the forces are said to be balanced. This does not necessarily imply that all of the forces seem to be equal to one another.For the given question;
Let the mass of each triangle be 'T'.
The mass of each circle be 'C'.
The mass of circle is 6 grams; C = 6 grams.
Let the mass of each square be 'S'.
The mass of each square is given as 3 grams; S = 3 grams.
As, the hanger is in equilibrium.
Mass of the left side = mass of the right side;
Put the values;
2T + 6S + 3C = 2C + 3S + 5T
Simplify the equation;
6S + 3C - 2C - 3S = 5T - 2T
3S + C = 3T
Or
3T = 3S + C
Put the values
3T = 3×3 + 6
3T = 15
T = 5
Thus, the mass of each triangle is 5 grams.
