Henry can write 5 pages of his novel in 3 hours. At this rate, how many pages can Henry write in 8 hours?
Given that Henry can write 5 pages in 3 hours, his rate is 5/3 pages per hour. Multiplying this rate by 8 hours, we get approximately 13.33 pages. Therefore, Henry can write approximately 13 to 14 pages in 8 hours at the given rate.
Explanation:The subject of this question is mathematics, specifically, it is dealing with the concept of rates. Given that Henry can write 5 pages in 3 hours, we can set up a rate, which is simply a ratio that compares quantities in different units. So, Henry's rate of writing is 5/3 pages per hour.
To find out how many pages Henry can write in 8 hours at this rate, we multiply his rate (5/3) by the number of hours (8 hours). So, (5/3) x 8 = 40/3 = 13.33. However, since we cannot have a fraction of a page, we can round this to 13 pages for a conservative estimate or to 14 pages for a liberal estimate.
So, at the rate given, Henry can write approximately 13 to 14 pages in 8 hours.

the number 1 is it's own multiplicative inverse. name another number with this property.
The number -1 is its own multiplicative inverse, just like the number 1, because multiplying -1 by itself results in 1.
The number 1 is indeed its own multiplicative inverse because when you multiply it by itself, you get 1. The property of a number being its own multiplicative inverse means that the number multiplied by itself equals 1. There is another number with this property, which is -1. When you multiply -1 by itself (-1 x -1), the result is 1. Therefore, -1 is also its own inverse when it comes to multiplication.
This concept is rooted in the properties of identity elements and inverses within the mathematical field of abstract algebra. When considering the set of numbers 1 and -1, they form an abelian group under the operation of multiplication. In this group, every element is its own inverse, and the identity element for multiplication is 1, as any number multiplied by 1 yields the original number.

I am joyous to assist you anytime.
The point (-4,-3) is not a solution to both Equation C: 2y-3x=6 and Equation D: -3x=4y. This is determined by substituting x with -4 and y with -3 in each equation and checking if the equation is balanced.
Explanation:To find which equation (-4,-3) is not a solution to, we substitute x with -4 and y with -3 into each equation, then see if both sides of the equation are equal.
For equation A: 5(-4) + 2(-3) equals -20 - 6, which is -26. So, (-4,-3) is a solution to this equation.For equation B: -3 equals 1 + (-4), which is -3. So, (-4,-3) is also a solution to this equation.For equation C: 2(-3) - 3(-4) equals -6 + 12, which equals 6. This equation does not equal 6. Therefore (-4,-3) is not a solution to this equation. For equation D: -3 equals 4*(-4), which is -16. This equation does not equal -16. So, (-4,-3) is also not a solution to this equation.So, (-4,-3) is not a solution to both Equation C: 2y-3x=6 and Equation D: -3x=4y.

x+y=-9. 5x-2y=32. elimination using manipulation
Answer:
x=2, y=11.
Step-by-step explanation:
x + y = -9.
5x - 2y = 32 Multiply the first equation by 2:
2x + 2y = -18 Adding the last 2 equations to eliminate y:
7x = 14
x = 2,
Substitute x = 2 in the first equation:
2 + y = -9
y = -9 - 2

Anna's running time for a race was 23.1 seconds.Another runner's time was 5.86 seconds faster.Find the other Runners time

17.24
Step-by-step explanation:
Simple subtraction of decimals because the other runner was faster:
23.10
-5.86
=
17.24
The other Runner's time is 17.24 seconds.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
Given that Anna's running time for a race was 23.1 seconds
And another runner's time was 5.86 seconds faster
It took Anna 23.1 seconds to complete a race.
Since the other runner was quicker,
So we did a simple decimal subtraction,
⇒ 23.10 - 5.86
⇒ 17.24
So, It took other runners 17.24 seconds to complete a race.
Hence, the other Runner's time is 17.24 seconds.

The relation Q is described as a list of ordered pairs, shown below.
Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) }
Domain: {-2,-1,0,4}
Range: {-2,2,3,4}
Step-by-step explanation:
Because its the answer
The Domain: {-3,-1,1} and Range: {-1,2,4,5}
What is domain and range?Domain – All of the values that go into a relation or a function are called the domain.
Range – All of the entities (output) which emerge from a relation or a function are called the range.
All input values that are used (independent values) forms the Domain set.
All output values that are used (dependent values) forms the Range set.
Example: Given Function:- f = 2x+1 , Find the domain, range if 1<=x<=5.
The values of x lies from 1 to 10.
So, domain is {1, 2, 3, 4, 5}.
The values of f obtained by putting domain elements in the function will be range.
So, if x=1 then f = 2(1)+1 = 3,if x=2 then f = 2(2)+1 = 5, if x=3 then f = 2(3)+1 =7, if x=4 then f = 2(4)+1 = 9, if x=5 then f = 2(5)+1 = 11.So, range is {3,5,7,9,11}.
We have relation Q as
Q = { (-2, 4), (0, 2), (-1, 3), (4, -2) }
so, we know domain are the input values
Domain: {-2,-1,0,4}
and range are the output values
Range: {-2,2,3,4}
