Answer:
V=3
Step-by-step explanation:
9v=27
You have to get v on its own so you have to do the inverse operation which in this case would be division, 9/9, what you do to one side you have to do to the other so 27/9
That’s would separate v from the other numbers and so V=3
9v=27
9v/9=27/9
V=3
Answer: v=3
Step-by-step explanation:
Simplifying
9v + -27 = 0
Reorder the terms:
-27 + 9v = 0
Solving
-27 + 9v = 0
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '27' to each side of the equation.
-27 + 27 + 9v = 0 + 27
Combine like terms: -27 + 27 = 0
0 + 9v = 0 + 27
9v = 0 + 27
Combine like terms: 0 + 27 = 27
9v = 27
Divide each side by '9'.
v = 3
Simplifying
v = 3
What is 90.125 written in expanded form? A. 9 × 10 + 1 × 1 + 2 × 1 10 + 5 × 1 100 B. 9 × 1 + 1 × 1 10 + 2 × 1 100 + 5 × 1 1 , 000 C. 9 × 10 + 1 × 1 10 + 2 × 1 100 + 5 × 1 1 , 000 D. 9 × 1 + 1 × 1 100 + 2 × 1 1 , 000 + 5 × 1 10 , 000
Using digit concepts, it is found that, in expanded form:
[tex]90.125 = 9 \times 10^1 + 0 \times 10^0 + 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]
--------------------
Each number can be divided into an integer part and a decimal part. For 90.125, the integer part is 90 and the decimal part is 0.125.In the integer part, starting from the last digit, each is multiplied by the "next" power of 10, thus:[tex]90 = 0 \times 10^{0} + 9 \times 10^{1} = 9 \times 10^{1} + 0 \times 10^{0}[/tex]
For the decimal part, starting from the first decimal digit, the same logic applies, using negative powers of 10 starting at -1, thus:[tex].125 = 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]
Combining the integer and decimal parts, we get that the number in expanded form is:
[tex]90.125 = 9 \times 10^1 + 0 \times 10^0 + 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]

Answer:
a = - 1.1
Step-by-step explanation:
The condition for a single variable function f(x) to be decreasing is f'(x) < 0.
f(x) = 4/x^2 - 6x + 9
Then, differentiating with respect to x on both sides we get,
f(x) = 4(-2)(1/x^3) - 6 < 0
-8/x^3 - 6 < 0
8/x^3 + 6 > 0
{Dividing both sides with - 1 and hence the inequality sign changes}
8/x^3 > -6
8 > - 6x³ {Multiplying both sides with x³}
6x³ > - 8 {Interchanging the sides}
x^3 > -8/6
⇒ x > - 1.1
So, a = - 1.1
Answer:
a = 3
Step-by-step explanation:
The function can be written as ...
f(x) = 4/(x -3)^2
This has a vertical asymptote at x=3 and will be decreasing for all values of x to the right of that -- on the interval (3, ∞).
a = 3

BRAINLIEST TO THE FIRST PERSON TO ANSWER!!Maria solved an equation as shown below.
3 (x + 6) = 5 (x minus 4). 3 x + 18 = 5 x minus 20. 38 = 2 x. 19 = x.
What is the solution to Maria’s equation?
19
38
no solution
infinitely many solutions
Answer:
19
Step-by-step explanation:
3(x + 6) = 5(x - 4)
Distribute on both sides.
3x + 18 = 5x - 20
Subtract 3x from both sides. Add 20 to both sides.
38 = 2x
Divide both sides by 2.
19 = x
Maria followed the steps shown above and solved the equation correctly.
The solution is x = 19.

solve 3(3x - 6) = 18
Steps to solve:
3(3x - 6) = 18
~Distribute left side
9x - 18 = 18
~Add 18 to both sides
9x = 36
~Divide 9 to both sides
x = 4
Best of Luck!
Answer:
x = 4
Step-by-step explanation:
Let's work on isolating (3x - 6). Start by dividing both sides of 3(3x - 6) = 18 by 3, obtaining:
3x - 6 = 6.
Next, add 6 to both sides:
3x = 12
Finally, divide both sides by 3:
x = 4
Find the cardinal number of the set
C = {x|x € N, 30 < x < 56 and x is divisible by 6},
=====================================================
Explanation:
We're given the following
[tex]C = \{ x | x \in \mathbb{N}, \ 30 < x < 56, \ \text{ x is divisible by 6}\}[/tex]
which means that we have a set of natural numbers between 30 and 56, excluding both endpoints, and the set of numbers are also multiples of 6.
So looking at the multiples of 6 that are between 30 and 56 leads us to
{30, 36, 42, 48, 54}
but we cross off 30 as we want x to be larger than that, so we get this updated final list
{36, 42, 48, 54}
There are four items in this final list so the cardinality of the set described is 4. The cardinality is just the number of items in a given set.

T(d) is a function that relates the number of tickets sold for a movie to the number of days since the movie was released.
The average rate of change in TQ) for the interval d = 4 and d = 10 is 0. Which statement must be true?
O The same number of tickets was sold on the fourth day and tenth day.
O No tickets were sold on the fourth day and tenth day.
O Fewer tickets were sold on the fourth day than on the tenth day.
More tickets were sold on the fourth day than on the tenth day.
Answer: The same number of tickets was sold on the fourth day and tenth day.
Step-by-step explanation:
Given: [tex]T(d)[/tex] is a function that relates the number of tickets sold for a movie to the number of days 'd' since the movie was released.
Also, the average rate of change in T(d) for the interval d = 4 and d = 10 is 0.
Since the average rate determines the rate of change in the dependent variable (T(d)) with respect to the independent variable (d).
It means that there is no change from 4th day to 10th day in the number tickets sold.
Hence, the correct option is "The same number of tickets was sold on the fourth day and tenth day."

Gold mines in northern Nevada produce an average of 3.2 grams of gold per short ton (2,000 pounds) of ore. The value of gold is usually reported in troy ounces (ozt), and a troy ounce is equal to 31.1 grams (g). On average, how many troy ounces of gold are extracted from one short ton of Nevada ore
Answer:
0.1028938
Step-by-step explanation:
Given the following :
Average gold production in Northern Nevada =3.2 grams per short ton (2000 pounds)
Value of gold is measured in Troy ounces (ozt)
1 Troy ounces = 31.1 grams(g)
Number of Troy ounces of gold extracted from one short ton of Nevada ore ; let the number be t:
1 ozt = 31.1 g
t = 3.2 g
Cross multiply :
31.1 × t = 3.2 × 1
31.1t = 3.2
t = 3.2 / 31.1
t = 0.1028938 ozt
Hence, On average, 0.1028938 ozt of gold is extracted from one short ton of Nevada ore

Answer:
x= 105 also because it's a z angle
y= 180-105
=75
x=z which is 105, because they are alternative angles.
The given angle of 105 and angle z are consecutive interior angles and need to equal 180 degrees.
Z = 180-105 = 75 degrees
Angle z and angle c are vertical angles and are identical so angle x also equals 75 degrees
Angle y and 105 are supplementary angles and when added equal 180
Angle y is 180-105 = 75
X, y and z are all 75 degrees

Answer: 7/12
Step-by-step explanation:
given data:
Box A
white ball = 1
red ball = 2
total ball = 3.
Box B
white ball = 1
red ball = 3
total ball = 4
Probability of picking a white ball as the final pick.

Question 4 25 points)
Answer:
A. V + 18 < 30
Step-by-step explanation:
First of all, less than is the sign that points to the left,
Secondly, I'm guessing that y is actually V,
Before Ray gave Jan cards, she had 18,
so it is 18 plus V (the number of cards Ray gave her),
SO,
V + 18 < 30
