Answer:
[tex](x^2)^2=x^4[/tex]
Step-by-step explanation:
Because of the power of a power property states that [tex]((x^n)^m)=x^{n\times{m}}[/tex], where n and m are real numbers, then, the expression you have just posted can be simplified by applying this property to [tex](x^2)^2=x^{2\times2}=x^4[/tex].
The cost of a rental car at a certain company is a $50 fee plus $0.40 for each mile driven up to 100 miles. For every
mile over 100 miles it is $0.50 per mile. What would the total cost be for renting the car and driving it 120 miles?
A. $40
B. $50
C. $90
D. $100
E. $110
Answer:
D
Step-by-step explanation:
50 + .40(100) = 90
.50(20) = 10
90 + 10= 100
Answer:
D: 100
So the first multiply 0.4 times 100 which you would get 40 now add the 50 dollar fee to 40 which you would get 90 dollars. Now for the 20 miles remaining multiply 0.5 times 20 which you would get 10. Now add everything together 90+10 which would equal 100.

How do you get 24 using 1, -6, -7, -3
Answer:
24
Step-by-step explanation:
We want to set up an expression involving 1, -6, -7, -3.
-6*-3--7+1
We use BODMAS to simplify:
We multiply to get:
18--7+1
We now add to obtain:
18--6
Note that negative negative gives addition.
Therefore:
18+6
This finally simplifies to:
24
Solve: 2(23 + a) = 34
Answer:
a = −6
Step-by-step explanation:
Step 1: You should divide both sides by 2.
[tex]23+a=\frac{34}{2}[/tex]
Step 2: then simplify [tex]\frac{34}{2}[/tex] into 17.
23 + a = 17
Step 3: next, you need to subtract 23 from both sides.
a = 17 − 23
Step 4: lastly, Simplify 17 − 23 to −6 and you're done!
a = −6
Answer:
a = -6
Step-by-step explanation:
2 (23 + a) = 34
46 + 2a = 34
2a = 34 - 46
2a = - 12
a = - 12/2
a = - 6

Allie and Sarah decided that they want to purchase renters insurance for the apartment they share. They made a list of all of the items to be covered by the insurance policy, along with their estimated values. If the items to be covered total more than $3000, the insurance company charges an annual premium of 23% of the total value of the items. If the items to be covered total $3000 or less, the insurance company charges an annual premium of 20% of the total value of the items. Using the list of items Allie and Sarah provided, determine their monthly renters insurance premium. Allie's Stuff Sarah's Stuff TV ($250) Stereo ($75) Stereo ($150) Bicycle ($250) CD's ($225) CD's ($130) DVD's ($385) DVD's ($300) Bicycle ($400) IPOD ($80) Microwave ($30) Computer ($675) Laptop Computer ($950) a. $65.00 b. $74.75 c. $325.00 d. $780.00
Answer:
The answer is b. $ 74.75
Step-by-step explanation:
First, we need to gather the data from the question.Data:
Let x be the value of items to be insured.
1. if the items are more than $ 3 000 it means that x is greater than $ 3000 and the annual premium will be 23 % of the total value.
2. if the items are less or equal to $ 3 000, it means that x ≤ $ 3 000 ( in other words, x is less than or equal to $ 3 000)
Second, we find the total worth of all the items. Adding up all the values gives $ 3900 which is more than $ 3 000. Therefore, rule 1 applies.The annual premium for the goods will be:
annual premium = 23 % × $ 3900
= $ 897
However, the premium is supposed to be paid monthly. Divide the total premium by 12 to get:
$ 897/12 = $ 74.75

What is eight more than the number of children is 24 as a word equation
Answer:
Eight plus twenty four equals thirty two
have an amazing day! (❁´◡`❁)
Step-by-step explanation:
The word equation for "eight more than the number of children is 24" can be written as:
Number of children + 8 = 24
Let's break it down step by step:
1. Identify the unknown: The unknown in this equation is the number of children. Let's represent it as "x".
2. Translate "eight more than the number of children" into mathematical language: "Eight more than" means adding 8 to the number of children.
3. Write the equation: The equation becomes x + 8 = 24.
To find the value of x, we need to isolate it on one side of the equation. We can do this by subtracting 8 from both sides:
x + 8 - 8 = 24 - 8
Simplifying further:
x = 16
Therefore, the number of children is 16.
It's important to note that the word equation can be translated into different mathematical expressions. For example, another way to represent "eight more than the number of children is 24" would be:
Number of children = 24 - 8
This equation would also yield the same answer: 16.
Remember, word equations help us represent real-life situations in mathematical form, allowing us to solve problems and find solutions.

Solve: x + 1.5= 5.7
How do I solve this?
Answer:
4.2
Step-by-step explanation:
5.7-1.5=4.2
Answer: x = 4.2
Explanation: If we're asked to solve for x in the equation x + 1.5 = 7.5, what we're really being asked to do is get x by itself on one side of the equation.
So if we take a look at the left side of our equation, notice that 1.5 is being added to x so in order to get x by itself, we must subtract 1.5 from the left side of the equation. Now remember your first rule of solving equations. If we subtract 1.5 from the left side of the equation, we must also subtract 1.5 from the right side of the equation.
So on the left side our +1.5 and -1.5 cancel out and we're simply left with x. On the right side of the equation,
5.7 - 1.5 simplifies to 4.2 so our answer is x = 4.2.
The nice thing about solving equations is that you can always check your answer by plugging it back in to the original equation.
So here, we're gonna plug a 4.2 back in for x in the original equation and we get (4.2) + 1.5 = 5.7.
Since 4.2 + 1.5 = 5.7 is a true statement, our answer checks and we know that it's right.
Simplify.

Answer:
2) Option 9.4 is correct
Therefore the length of the given line segment is [tex]s=9.4[/tex] units
3) Option (1,1) is correct
Therefore the midpoint of the given line segment is M=(1,1)
Step-by-step explanation:
2) Given that the line segment CD with endpoints C at (-3,1) and endpoint at D (5,6)
To find the length of the given line segment :
That is to find the distance of the end points using distance formula
[tex]s=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] units
Let [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] be the given points (-3,1) and (5,6) respectively
Substitute the points in the distance formula we have
[tex]s=\sqrt{(5-(-3))^2+(6-1)^2}[/tex] units
[tex]=\sqrt{(5+3)^2+(5)^2}[/tex] units
[tex]=\sqrt{8^2+5^2}[/tex]
[tex]=\sqrt{64+25}[/tex]
[tex]=\sqrt{89}[/tex]
[tex]=9.4[/tex]
Therefore [tex]s=9.4[/tex] units
Option 9.4 is correct
Therefore the length of the given line segment is [tex]s=9.4[/tex] units
3) Given that the line segment PG with point P at (-6,4) and point at G (8,-2)
To find the midpoint of the given line segment :
Midpoint formula is [tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Let [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] be the given points (-6,4) and (8,-2) respectively
Substituting the points in the midpoint formula we get
[tex]M=(\frac{-6+8}{2},\frac{4-2}{2})[/tex]
[tex]=(\frac{2}{2}+\frac{2}{2})[/tex]
[tex]=(1,1)[/tex]
Therefore M=(1,1)
Therefore option (1,1) is correct
Therefore the midpoint of the given line segment is (1,1)
What are the roots of the equation x^2 + -9=0
Answer:
x = 3 or x = -3
Step-by-step explanation:
If x^2 - 9 = 0 we transfer 9 to the right side of the equation and it's change negative sign to positive while doing so
now we have x^2 = 9 the square of a number must be equal to a positive number in real numbers
but the root can be either negative or positive so we say x = 3 or x = -3
solve the system of equations by graphing. x+y=-9 4x+y=-19
For this case we have the following system of equations:
[tex]x + y = -9\\4x + y = -19[/tex]
We multiply the first equation by -4:
[tex]-4x-4y = 36[/tex]
We have the following equivalent system of equations:
[tex]-4x-4y = 36\\4x + y = -19[/tex]
We add the equations:
[tex]-4x + 4x-4y + y = 36-19\\-3y = 17\\y = - \frac {17} {3}[/tex]
We find the value of the variable "x":
[tex]x = -9-yx = -9 - (- \frac {17} {3})\\x = -9 + \frac {17} {3}\\x = \frac {-27 + 17} {3}\\x = - \frac {10} {3}[/tex]
Thus, the solution of the system is:
[tex](x, y): (- \frac {10} {3}, - \frac {17} {3})[/tex]
See the graphic in the attached image

[tex](x, y): (- \frac {10} {3}, - \frac {17} {3})[/tex]

the value of x varies with y and when x=1/3 y=12 write an equationto represent the variation
Answer:
y = 36x
Step-by-step explanation:
Given that x and y vary directly then the equation relating the is
y = kx ← k is the constant of variation
To find k use the condition x = [tex]\frac{1}{3}[/tex], y = 12, then
k = [tex]\frac{y}{x}[/tex] = [tex]\frac{12}{\frac{1}{3} }[/tex] = 12 × 3 = 36
y = 36x ← equation of variation
