which expression is equivalent to the given expression?
Step-by-step explanation:
[tex]( \frac{6ab}{(a {}^{0} {b}^{2} ) {}^{4} } ) \\ \\ =( \frac{6ab}{1 \times {b}^{8} } ) \\ \\ = \frac{6a}{ {b}^{7} } [/tex]
Choice C. is equivalent.
Let's first simplify, starting with the denominator.
a to the power of 0 is 1. —> any value to the power of 0 is 1.
That leaves us with (1b^2)^4. Now we can distribute the exponent. But before that, let's get rid of the coefficient 1, which isn't necessary.
Now we are left with (b^2)^4.
Let's use the power of the power rule, which means that we multiply the exponent by the exponent. The denominator is now b^8.
Looking at the numerator, there is a b, which has a hidden exponent of one. —> We can get rid of it by taking away its exponent of 1 with the b^8 from the denomiator.
. . . b^1 goes away, and b^8 becomes b^7.
We cannot simplify any further, therefore the final expression is. . .
6a/b^7.y÷7+15=21 Please answer & quick!!
Answer: Y=42
Step-by-step explanation:
Y/7+15=21
Subtract 15 on both sides
Y/7=6
Divide by 1/7 on both sides (or multiply 7 on both sides, it’s the same results)
Y=42
x/2 + 3/2 < 5/2
thank youuu :)
Answer:
x < 2
Step-by-step explanation:
x/2 + 3/2 < 5/2
~Simplify
1/2x + 3/2 < 5/2
~Subtract 3/2 to both sides
1/2x < 2/2
~Simplify
1/2x < 1
~Multiply 2 to both sides
x < 2
Best of Luck!

How to convert 3100.0 × 10² into scientific notation
Answer: 3.1 x 10 ^5
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
The required scientific notation of the number 3100 * 10² is [tex]3.1*10^5[/tex].
Given that,
To convert 3100.0 × 10² into the scientific notation.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
What is scientific notation?Scientific notation is appropriate formate of large values like 100000 = [tex]10^5[/tex] is called scientific notation,
Here,
3100 * 10² = 3.1 * 1000 * 10²
3100 * 10² = 3.1* 10³ * 10²
3100 * 10² = 3.1 ([tex]10^{3+2}[/tex])
3100*10² = [tex]3.1*10^5[/tex]
Thus, the required scientific notation of the number 3100 * 10² is [tex]3.1*10^5[/tex].

It takes Mike 10 minutes to do an oil change and 20 minutes to do a tire change. He's working for 60 minutes today. He only has enough tires in stock to change them on 2 cars. If he can earn $10 per oil change, and $40 per tire change, how many of each should he do to maximize profits?
Answer:
2 tire changes and 2 oil changes.
2($40) + 2($10) = $80 + $20 = $100

In a certain region, 6% of a city’s population moves to the surrounding suburbs each year, and 4% of the suburban population moves into the city. A 2019 census measures 10,000,000 residents in the city and 800,000 in the suburbs. (a) Set up a difference equation (of the form ~xn+1 = A~xn) that describes this situation, where ~x0 is the initial population in 2019. (b) Estimate the populations in the city and suburbs two years later, in 2021.
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Following are the differential equation:
[tex]\to P(C,S)t+1 = P(C,S)t+(- 0.06Ct +0.04St, 0.06Ct - 0.04St ) \ \ \ \\\\or \ \ \ \ \ \ \ \\\\ \to (0.94Ct + 0.04St, 0.96St + 0.06Ct)[/tex]
In equation:
[tex]\to t = 0, \ as \ 2019\\\\\to Ct = 10,000,000 \\\\\to St = 800,000,000\\[/tex]
[tex]\to P(C, S)1 = (0.94Ct + 0.04St, 0.96St + 0.06Ct) \\\\[/tex]
[tex]= (0.94(10000000) + 0.04(800000), 0.96(800000) + 0.06(10000000))\\\\ = (9,400,000 + 32,000), (768,000 +6000000))\\\\ = (9432000, 1368000)[/tex]
[tex]\to P(C, S)2 = (0.94(9432000) + 0.04(1368000), 0.96(1368000) + 0.06(9432000))[/tex]

Drag numbers to complete the table for missing values of x, x2, and x3.
Answer: The filled out table is shown in the attachment below
Row 1 = 2, 4, 8
Row 2 = 6, 36, 216
=======================================================
Explanation:
In the first row we have x^2 = 4. Apply the square root to both sides to get x = 2. It appears your teacher is making x positive.
So we'll have 2 in the first box of row 1.
If x = 2, then x^3 = 8 after cubing both sides.
In other words, x^3 = 2^3 = 2*2*2 = 8
The value 8 goes in the other box of row 1.
---------------
For row 2, we use x = 6 to square that to get x^2 = 6^2 = 6*6 = 36.
36 will go in the blank box for row 2

Step-by-step explanation:
An athletic club buys car magnets and pom-poms for club members. The car magnets cost 4.95 each, and pom-poms cost each. The athletic club spends a total 580 of before tax, on a total of $300$ items. Each club member should receive $1$ car magnet and $2$ pom-poms. If $x$ represents the number of car magnets, and $y$
Answer:
Each car magnet costs $4.95 and each pom-pom costs $0.425
The club spent $495 on 100 car magnets and $85 on 200 pom-poms.
Step-by-step explanation:
I guess that we have to calculate the price of pom-poms and how much money was spent purchasing car magnets and pom-poms.
x + y = 300
2x = y (now we replace y)
x + 2x = 300
3x = 300
x = 100
The club purchased 100 car magnets and 200 pom-poms.
To determine the price of each pom-pom:
($4.95 x 100) + 200P = $580
$495 + 200P = $580
200P = $85
P = $0.425

Justify each step in solving the equation 7(x+1)+11x=-2x-5 by writing a reason for each statement.
Given:
The equation is
[tex]7(x+1)+11x=-2x-5[/tex]
To find:
The reason for each statement.
Solution:
We have,
[tex]7(x+1)+11x=-2x-5[/tex]
Using distributive property, we get
[tex]7x+7+11x=-2x-5[/tex]
On combine like terms, we get
[tex]18x+7=-2x-5[/tex]
Using addition property of equality, add 2x on both sides.
[tex]20x+7=-5[/tex]
Using subtraction property of equality, subtract 7 from both sides.
[tex]20x=-12[/tex]
Using division property of equality, divide both sides by 20.
[tex]x=-\dfrac{12}{20}[/tex]
[tex]x=-\dfrac{3}{5}[/tex]
Therefore, the required reasons are:
2. Distributive property
3. Combining like terms
4. Addition property of equality
5. Subtraction property of equality
