Oliver drives 45 miles per hour.Write an expression that represents the distance in miles he will travel for h hours driven.
Answer:
45h=d
Step-by-step explanation:
If d represents the distance in miles, then the equation would be 45h=d because when you multiply 45 by the amount of hours h, then you would get the total distance in miles. For example, Oliver drives 45 miles per hour for 3 hours. When we substitute h, the number of hours, for 3, then we get:
45(3)=d
And all we need to do is to multiply them together to get d, which in this case, it is 135 miles.

Simplify: 20 + √216 all over 2
Answer:
the answer is 10+3[tex]\sqrt{6\\}[/tex] or 17.35
Answer:
10 + 3(√6)
Step-by-step explanation:
To simplify this expression, take what is divisible by 2 in the numerator (top) out of the fraction. For the square root number, change it to a mixed radical form (an equivalent number multiplied by a smaller root) by taking out square numbers.
[tex]\frac{20+\sqrt{216}}{2}[/tex] Split the fraction to see what can be divided
[tex]=\frac{20}{2}+\frac{\sqrt{216}}{2}[/tex] 20/2 = 10
[tex]=10+\frac{\sqrt{216}}{2}[/tex] Simplify the root. 216 = 4*9*6
[tex]=10+\frac{\sqrt{4*9*6}}{2}[/tex] 4 and 9 are square numbers. Take out the square root of those factors.
[tex]=10+\frac{2\sqrt{9*6}}{2}[/tex] Took out the √4 first.
[tex]=10+\frac{2*3\sqrt{6}}{2}[/tex] Took out √9. (√4)(√9) = 2*3
[tex]=10+\frac{6\sqrt{6}}{2}[/tex] The mixed radical is 6√6. Divide it by 2.
[tex]=10+3\sqrt{6}[/tex] Answer

What is the solution to 4log4(x+8)=4^2
Answer:2492
Step-by-step explanation:
4Log4(x+8)=4^2
Divide both sides by 4 we get
Log4(x+8)=4^2/4
Log4(x+8)=4
4(x+8)=10^4
4(x+8)=10000
Open brackets
4x+32=10000
Subtract 32 from both sides
4x+32-32=10000-32
4x=9968
Divide both sides by 4
4x/4=9968/4
X=2492
Austin correctly answered 92% of the questions on the geography quiz. Liz and third 47 of the 50 questions correctly who earned a higher score? Explain.
Final Answer:
Liz's score is higher than Austin's
Explanation:
To solve this problem, first we need to calculate the percentage of correct answers that Liz got. We know that Liz answered 47 questions correctly out of a total of 50 questions. To calculate the percentage, we'll divide the number of questions Liz answered correctly by the total amount of questions and then multiply by 100.
This gives us the percentage of correct answers that Liz got.
We then compare it to the percentage that Austin got, which is 92%.
Doing so, we find that Liz's score is higher than Austin's. Hence, Liz earned a higher score.

What are accepted without proofs in a logical system
Postulates, Axioms, and Common Notions are accepted without proofs in a logical system.
Explanation:
Postulates or axioms are those statements which are considered to be true and these serve as a starting point or a premise for further arguments or reasoning purposes.
Common notions which are sometimes referred to as axioms represents the magnitudes of one kind.
In mathematics, axioms are classified into two types namely,
1. Logical axioms: Used in two distinguishable but relatable senses.
2. Non-logical axioms: Substantive assertions based on the elements of any theory.

when x-y=3 work out the value of y-x
The value of y-x is (-3)
Solution:
Given: The value of x-y=3
To find: The value of y-x
[tex]\bold{x-y=3\rightarrow (1)}[/tex]
Let's multiply the equation (1) by (- 1) on both sides,
[tex]\Rightarrow\bold{(x - y)\times(- 1) = 3\times(- 1)}[/tex]
[tex]\Rightarrow\bold{-(x-y)=-3}[/tex]
On multiplying the sign,
[tex]\Rightarrow\bold{(-x+y)=-3}[/tex]
The above equation can also be written as,
[tex]\Rightarrow\bold{y-x=-3\rightarrow \text{(The required equation)}}[/tex]
Multiplication of signs:
[tex]\Rightarrow( + )\times( + ) = ( + )[/tex]
[tex]\Rightarrow( + )\times( - ) = ( - )[/tex]
[tex]\Rightarrow( - )\times( + ) = ( - )[/tex]

Question:
Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(m) as a function of months m.
Answer:
The system of equations that models the height of each species H(m) as a function of months m is: [tex]H_A(m) = 25 + 3m \text{ and } H_B(m) = 10+8m[/tex]
Solution:
[tex]H_A(m)[/tex] = the height of species A as a function of months m
[tex]H_B(m)[/tex] = the height of species B as a function of months m
Species A is 25 cm tall and grows 3 cm per month
Let "m" be the number of months
Therefore, a equation is framed as:
Species A : 25 cm + 3(number of months)
[tex]H_A(m) = 25 + 3m[/tex]
Species B is 10 cm tall and grows 8 cm per month
Therefore, a equation is framed as:
Species B : 10 cm + 8(number of months)
[tex]H_B(m) = 10+8m[/tex]
Thus the system of equations that models the height of each species H(m) as a function of months m is: [tex]H_A(m) = 25 + 3m \text{ and } H_B(m) = 10+8m[/tex]

The velocity v of an object rolled down an inclined plane is given by the formula v=
53d, where d is the distance the object has rolled, Solve the formula for d.
Final answer:
To find the distance an object has rolled down an inclined plane from the velocity equation v = √(53d), square both sides of the equation and then divide by 53 to solve for d.
Explanation:
The velocity v of an object rolled down an inclined plane is given by the formula v = √(53d), where d is the distance the object has rolled. To solve this equation for d, we can square both sides of the equation to remove the square root. The steps are as follows:
Square both sides of the equation: v² = (53d)².
Divide both sides by 53 to isolate d: d = v² / 53.
Now, d represents the distance the object has rolled down the inclined plane as a function of its velocity v.
Is the relation given by the set of ordered pairs below a function? (Yes or No)
(3,-7), (2,4), (-3,-7), (3,0), (0,2)
Answer:
No
Step-by-step explanation:
The vertical line test can be used to determine whether a graph represents a function. A vertical line includes all points with a particular X value. The Y value of a point where a vertical line intersects a graph represents an output for that input X value. If we can draw any vertical line (left to right) that intersects a graph more than once, then the graph does not define a function because that X value has more than one output. A function has only one output (X) value for each input value.
EXAMPLES:
(3,-7), (2,4), (-3,-7), (3,0), (0,2)
The first numberin each set is th X value or output.
The 3 has two Y values, -7 and 0, it can only have one Y value.
Only one X can have a one Y vale to make it a function.
The relation given by the set (3,-7), (2,4), (-3,-7), (3,0), (0,2) is not a function, since the x-value 3 corresponds to two different y-values (-7 and 0).
Explanation:In mathematics, a relation is a set of ordered pairs. For that set to be a function, each input (x-value) should correspond to only one output (y-value). That means no two ordered pairs should have the same x-value but different y-values.
Looking at your given set (3,-7), (2,4), (-3,-7), (3,0), (0,2), we can see that the x-value 3 corresponds to two y-values: -7 and 0. Therefore, this relation is NOT a function.

What is the slope of a line perpendicular to the line with equation y = 3x – 1? –3 –1 3
[tex]m=-\frac{1}{3}[/tex] is the slope of a perpendicular line.
Step-by-step explanation:
For two lines to be perpendicular to each other, their slope must be mutually negative reciprocal (to check if the numbers are multiplied, they should be -1).
Given equation:
y = 3 x – 1
We know the standard slope equation, as y = m x + b. When comparing this with the given equation, we get slope value,
m = 3
But in question, they asked to find slope of a line perpendicular to the line. So, apply this ‘the perpendicular slope will be the opposite (negative) reciprocal of the original slope’
Therefore, the slope of a perpendicular line is
[tex]m=-\frac{1}{3}[/tex]
