Answer:
They are not equivalent.
Step-by-step explanation:
x(3x) = 4x
x by itself = 1x
1x ( 3x ) = 4x
1x times 3x = 3x
3x = 4x is not equivalent.

Write the expression as a power with the base of 3 and find its value in the table of cubes
27·243
Answer:
27 · 243 = 3
=
Answer:
3^8 and 6,561
Step-by-step explanation:
1) Calculate, 3 to the power of what is 27?
Make a table of all of 3's powers until 10. i.e. 3^1 = 3, 3^2 = 9 ......
You will find that 3^3 = 27 and 3^5 is 243
3) Use the formula x^m * x^n = x^m+n and substitue our value.
It should look like this: 3^3 * 3^5 = 3^3+5 = 3^8
4) Make a table as described in step 2 and calculate all of 3's powers up to 10. Look at your table and you will find that 3^8 is equal to 6,561
5) The expression written as a power is
3^8 and
the value: 6,561

Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each. How many rides will Luka need to ride in order to spend $20?
Answer:
He would have to do 13 rides.
Step-by-step explanation:
If he initially pays $7, which lets him pay only $1 for each ride, so when he spends $20, he would have done 13 rides.
There are 13 rides will Luka need to ride in order to spend $20.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each.
Here, Luka need to ride in order to spend $20.
Let number of rides = x
So, We can formulate;
⇒ $7 + $1x = $20
⇒ 7 + x = 20
Solve for x as;
⇒ x = 20 - 7
⇒ x = 13

The sum of three odd numbers is odd and that added to an even number results in an odd number.
What are some other related concepts?An even number raised to the even or odd power is even and an odd number raised to the power of even or odd is always an odd number.
We know the sum of two even numbers is even, the sum of two odd numbers is also even and the sum of an odd and even number is odd and vice versa.
Given four numbers first two numbers are odd so their sum is even.
The next two numbers are even and odd so their sum is odd, Now the sum of even and odd is odd.

Two-thirds of the T-shirts in a T-shirt shop are blue. Three-fifths of those T-shirts are on sale. One-half of the blue T-shirts that are on sale are size medium. What fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium? Explain.
Let, total number of T-shirts are x.
Number of blue T-shirts = (2/3)x = 2x/3 .
Number of blue shirts on sale = (3/5)(2x/3) = 2x/5 .
Number of medium sized blue shirts on sale = (1/5)(2x/5) = 2x/25 .
Fraction of the shop's T-shirts are blue T-shirts that are on sale and are size medium = [tex]\dfrac{2x/25}{x}[/tex]= 2/25 . ( Number of medium sized blue shirts on sale divided by total number of T-shirts )

A ferris wheel has a diameter of 80 meters. How far does a rider travel in one complete rotation around the ferris wheel?
Given parameter:
Diameter of the ferris wheel = 80m
Unknown:
Distance covered in one complete rotation = ?
Solution:
One complete rotation will sweep through the circumference of the wheel.
So,
One complete rotation = Circumference of circle = 2 [tex]\pi[/tex] r
Where r is the radius;
Radius here is [tex]\frac{80}{2}[/tex] = 40m
So circumference = 2 x [tex]\pi[/tex] x 40 = 80[tex]\pi[/tex]
The distance the wheel sweeps through will be 80π m

The Fairview Library is getting ready to move to a bigger building. So, the librarians need to pack 2 tons of books into cardboard boxes. Each box can safely hold about 25 pounds of books. If they already packed 50 boxes, how many more boxes should they expect to use?
Given :
The librarians need to pack 2 tons of books into cardboard boxes. Each box can safely hold about 25 pounds of books. If they already packed 50 boxes.
To Find :
How many more boxes should they expect to use.
Solution :
We know, 1 ton = 2000 pounds
So, 2 ton = 4000 pounds
Minimum number of boxes required for safe handling :
[tex]n=\dfrac{4000}{25}\\\\n=160[/tex]
So, total 160 boxes required.
Therefore, 160 - 50 = 110 many more boxes should they expect to use.
Hence, this is the required solution.

) Suppose you are installing a wood floor in a square room. The cost to install the floor is $9 per square foot. The area of the room is given by the function A(x) = x 2 and the cost per square foot is given by the function C(A) = 9A. Which function can be used to find the total cost to install the wood floor? A) A(C(x)) B) C(A(x)) C) x(A(C)) D) x(C(A))
Answer:
The correct option is;
B) C(A(x))
Step-by-step explanation:
The given information are;
The cost to install the floor per square foot = $9
The area of the room is given by the function A(x) = x²
The function for the cost per square foot = C(A) = 9·A
We note that the total cost to install the wood floor = (The cost to install the floor per square foot) × (The area of the room)
∴ The total cost to install the wood floor = $9 × x²
Given that A(x) = x², we have;
The total cost to install the wood floor = $9 × A(x)
Also, given that C(A) = 9·A, we have;
C(A(x)) = 9·A(x)
Therefore;
The total cost to install the wood floor in dollar amount can be given by the function, C(A(x)) = 9·A(x)

A kindergarten teacher bought $21 worth of stickers and cardstock for his class. The stickers cost $1.50 a sheet and the cardstock cost $3.50 per pack. The equation 1.5s+3.5c=21 represents the relationship between sheets of stickers, s, packs of cardstocks, c, and the dollar amount a kindergarten teacher spent on these supplies.
1. Explain how we can tell that this graph represents the give equation.
2. What do the vertical and horizontal intercepts, (0,6) and (14,0), mean in this situation?
Answer:
Step-by-step explanation:
Teacher bought $21 worth of stickers and cardstock for his class.
Cost of stickers = $1.50 per sheet
Cost of 's' sheets = $1.5s
Cost of cardstock = $3.50 per pack
Cost of 'c' packs = $3.5c
Equation representing the relationship between sheet of stickers and packs of cardstocks will be,
1.5s + 3.5c = 21
3.5c = -1.5s + 21
1). [tex]c=-\frac{3}{7}x+6[/tex]
y-intercept of the line → (0, 6)
x-intercept of the line → (14, 0)
Therefore, equation of the line represents the line on the graph.
2). Vertical intercept (0, 6) represents that he can purchase maximum 6 packs of cardstock with $21.
Similarly, horizontal intercept (14, 0) represents that he can purchase maximum 14 sheets of stickers with $21.
Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6
Answer:
The answer is 2(3)+6
Step-by-step explanation:
The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.
Alicia bought two slices of pizza and a bottle of juice for $4.95. The juice was $1.65. How much is one slice of pizza?
Subtract the price of the juice from the total then divide the remaining amount by 2:
4.95 - 1.65 = 3.30
3.30 /2 = 1.65 per slice.

Find the zeros of the function f(x) = -5x2 + 4x - 1 by completing the square.
(leave in fraction form if necessary)
Answer:
The roots are;
x = (2 + i)/5 or (2-i)/5
where the term i is the complex number representing the square root of -1
Step-by-step explanation:
Here, we want to use the completing the square method to solve the quadratic equation;
f(x) = -5x^2 + 4x -1
Set the function to zero
0 = -5x^2 + 4x - 1
So;
-5x^2 + 4x = 1
divide through by the coefficient of x which is -5
x^2 - 4/5x = -1/5
We now take half of the coefficient of x and square it
= -2/5^2 = 4/25
add it to both sides
x^2 - 4x/5 + 4/25= -1/5 + 4/25
(x- 2/5)^2 = -1/5 + 4/25
(x - 2/5)^2 = -1/25
Take the square root of both sides
x - 2/5 = √( -1/25
x - 2/5 = +i/5 or -i/5
x = 2/5 + i/5 or 2/5 - i/5
