Answer:
x = [tex]\frac{5u+4y}{2-6z}[/tex]
Step-by-step explanation:
2(x - 2y) = 6xz + 5u ← distribute parenthesis on left side
2x - 4y = 6xz + 5u ( add 4y to both sides )
2x = 6xz + 5u + 4y ( subtract 6xz from both sides )
2x - 6xz = 5u + 4y ← factor out x from each term on the left side
x(2 - 6z) = 5u + 4y ← divide both sides by (2 - 6z)
x = [tex]\frac{5u+4y}{2-6z}[/tex]
7.003x10^-5 in standard form
Answer:
0.00007003 is the standard form of 7.003x10^-5. In scientific notation, the number is expressed as 7.003 multiplied by 10 raised to the power of negative five. To convert it to standard form, the decimal point has to move to the left by five places since the exponent is negative. The resulting number is a decimal with four zeros before the first nonzero digit. Standard form is a way of representing numbers that does not use exponents and is useful in comparing and performing operations on numbers.

my bike tire has a radius of 12 inches how much distance will i cover after 50 rotations
Therefore , the solution of the given problem of unitary method comes out to be 50 tyre rotations, you will have covered around 376.99 inches (or about 31.41 feet).
What is a unitary method?The well-known simple approach, real variables, and any crucial elements from the very initial And specialised inquiry can all be used to finish the work. Customers may then be given another chance to try the product in response. If not, significant impacts on our understanding of algorithms will vanish.
Here,
The circumference of the circle the bike tyre forms is equal to the distance travelled in one rotation of the tyre. The following formula determines a circle's circumference:
=> C = 2πr
where the mathematical constant is roughly equivalent to 3.14159 and r is the circle's radius.
Your bicycle tyre's radius in this instance is 12 inches. The tyre's circumference is as follows:
=> C = 2π(12) = 24π inches
You may easily calculate how far you will travel after 50 spins by multiplying the tyre's circumference by the number of turns:
=> Covered distance: 50 × 24π ≈ 376.99 inches
As a result, after 50 tyre rotations, you will have covered around 376.99 inches (or about 31.41 feet).

A soccer ball is kicked in the air off a 27.0-meter high hill. The equation h(t) = -2t^2 + 4t + 27 gives the approximate height h, in meters, of the ball t in seconds after it is kicked. Does the ball reach a height of 40 m?
The ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.
To determine if the ball reaches a height of 40 meters, we can substitute h(t) = 40 into the equation and solve for t.
40 = -2t² + 4t + 27
Rearranging the terms, we get:
2t² - 4t - 13 = 0
We can solve for t using the quadratic formula:
t = [4 ± √(4² - 4(2)(-13))]/(2(2))
t = [4 ± √(176)]/4
t ≈ 3.38 or t ≈ -0.88
Since time cannot be negative, we can discard the negative solution. Therefore, the ball reaches a height of 40 meters at approximately 3.38 seconds after it is kicked.

Read the paragraph and choose a sentence that describes it best. Because of the association with TERFs, many feminists have stopped identifying with radical feminism. Though some of their views may be similar to the original tenets of radical feminism, many feminists no longer associate with the term because they are trans-inclusive. TERF is not just transphobic feminism; it is a violent international movement that often compromises its feminist stances to partner with conservatives, with a goal to endanger and get rid of trans people, especially transfeminine people.

Write a sentence to explain each of your answers.
Exactly one-year later,
(a) Mean of the ages will be 13 years and 3 months.
(b) Range of the ages will be same 2 years and 7 months.
Part (a) : To find the mean of the ages of the same group of students exactly one year later, we add one year to each student's age and find the new mean.
New mean is : 12 years and 3 months + 1 year = 13 years and 3 months;
So the mean of the ages of the same group of students exactly one year later is 13 years and 3 months.

End of month 2 3 5 6 7 Previous balance $0.00 $900.00 $899.25 $898.50 $897.75 $897.00 $896 26 New charges $900.00 $0.00 $0.00 $0.00 $0.00 $0.00 $0.00 Payment Finance Principal received charges paid $0.00 $0.00 $0.00 $18.00 $17.99 $17.97 $17.96 $17.94 $17.93 How is the new balance calculated? $17.25 $17.24 $17.22 $17.21 $17.19 $17.18 $0.75 $0.75 $0.75 $0.75 $0.75 $0.75 New balance $900.00 $899.25 $898.50 $897.75 $897.00 $896.26 $895.51
Answer:$909.03
Step-by-step explanation:he new balance on Guadalupe's credit card is calculated as follows:
First, we calculate the interest charged on the previous balance. Since the APR is 23%, the monthly interest rate is 23%/12 = 1.92%. So the interest charged on the previous balance for the month is:
Interest = Previous balance x Monthly interest rate
= $900.00 x 1.92%
= $17.28
Next, we add the finance charge, which is calculated as 1% of the previous balance plus any new charges. So the finance charge for the month is:
Finance charge = 1% x (Previous balance + New charges)
= 1% x ($900.00 + $0.00)
= $9.00
The total amount due is the sum of the previous balance, the interest charged, and the finance charge:
Total amount due = Previous balance + Interest + Finance charge
= $900.00 + $17.28 + $9.00
= $926.28
The minimum payment due is 2% of the total amount due, which is:
Minimum payment = 2% x Total amount due
= 2% x $926.28
= $18.53
If the minimum payment is less than $25, the minimum payment due is $25. So in this case, the minimum payment due is $25.
Guadalupe made a payment of $18.00, which is less than the minimum payment due, so she will be charged a late fee in addition to the interest on the unpaid balance.
The principal paid is the difference between the payment made and the interest charged, which is:
Principal paid = Payment - Interest
= $18.00 - $17.28
= $0.72
The new balance is the sum of the previous balance, any new charges, and the interest charged, minus the payment made, plus any finance charge and late fee:
New balance = Previous balance + New charges + Interest - Payment + Finance charge + Late fee
= $900.00 + $0.00 + $17.28 - $18.00 + $9.00 + $0.75

The square on the right is a scaled copy of the square on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
The scale factor between a square of dimensions 7 by 7 and a scaled copy of dimensions 21/2 by 21/2 is 3/2 or 1.5.
We know that the dimensions of the square on the left are 7 by 7, and the dimensions of the square on the right are 21/2 by 21/2.
To find the scale factor, we can divide the dimensions of the square on the right by the dimensions of the square on the left
scale factor = (21/2) / 7
We can simplify this fraction by dividing both the numerator and the denominator by the greatest common factor, which is 7
scale factor = (21/2) / 7 = (21/2) * (1/7) = 3/2
Therefore, the scale factor is 3/2, or 1.5.

Evaluating the distance between the tree and the zip lineFrom the question, we have the following parameters that can be used in our computation:
y = -6/7x + 7
This represents the zip line
Convert the equation to standard form
This gives
7y = -6x + 49
So, we have
6x + 7y - 49 = 0
This means that
A = 6, B = 7 and C = -49
From the point (6, 14), we have
x = 6 and y = 14
The distance between the tree and the zip line is then calculated as
[tex]d = \frac{|ax + by + c|}{\sqrt{a^2 + b^2}}[/tex]
By substitution, we have
[tex]d = \frac{|6 * 6 + 7 * 14 - 49|}{\sqrt{6^2 + 7^2}}[/tex]

What is combinations?
Combinations are a mathematical concept used to count the number of ways that a certain number of items can be selected from a larger set of items without regard to the order in which they are selected.
We can use combinations to solve this problem. We need to choose 8 inquiries out of 16 for the first agent, and the remaining 8 inquiries will be handled by the second agent.
The number of ways to choose 8 inquiries out of 16 is:
C(16, 8) = 16! ÷ (8! * (16-8)!) = 12870
This is the number of ways the inquiries can be directed to one agent. Since there are two agents and each handles 8 inquiries, we need to divide this number by 2 to avoid counting each arrangement twice:
