the ratio of feet to yards is:
[tex]\frac{3feet}{1yard}[/tex]Now, the proportion to find the equivalent yards for 9 feet is:
[tex]\frac{3feet}{1yard}=\frac{9feet}{x\text{ yards}}[/tex]Let's solve for x:
[tex]\begin{gathered} x=\frac{9ft\times1yard}{3ft} \\ x=3\text{yards} \end{gathered}[/tex]Therefore, 9 feet=3 yards.
Which expression is equivalent to -12(3x -3/4)?
Answer:
- 36x + 9
Step-by-step explanation:
- 12(3x - [tex]\frac{3}{4}[/tex] ) ← multiply each term in the parenthesis by - 12
= - 36x + 9
Answer:
-36x + 9
Step-by-step explanation:
Given expression:
[tex]-12\left(3x-\dfrac{3}{4}\right)[/tex]
Apply the distributive rule:
[tex]\implies -12 \cdot 3x -12 \cdot -\dfrac{3}{4}[/tex]
Multiply -12 and 3x:
[tex]\implies -36x -12 \cdot -\dfrac{3}{4}[/tex]
Apply the rule -a(-b) = ab:
[tex]\implies -36x +12 \cdot \dfrac{3}{4}[/tex]
Convert 12 into a fraction:
[tex]\implies -36x +\dfrac{12}{1} \cdot \dfrac{3}{4}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{b} \cdot \dfrac{c}{d}=\dfrac{ac}{db}}:[/tex]
[tex]\implies -36x +\dfrac{36}{4}[/tex]
Divide the numbers:
[tex]\implies -36x +9[/tex]
Therefore, the equivalent expression to the given expression is:

List the partial products of 242 and 28.
The partial products of 242 × 28 are 4,000, 1,600, 840 and 336 and the value of 242 × 28 exists 6,776.
What is meant by partial product?To estimate the partial product of two numbers, first, we write both numbers as the sum of the place values of the digits. Multiply each place value of the first number by the place value of the second number.
Given: 242 × 28
(200 + 42) × (20 + 8)
(200 × 20) + (200 × 8) + (42 × 20) + (42 × 8)
simplifying the above equation, we get
200 × 20 = 4,000
200 × 8 = 1,600
42 × 20 = 840
42 × 8 = 336
The above values are the partial product.
4,000 + 1,600 + 840 + 336 = 6,776
Therefore, the partial products of 242 × 28 are 4,000, 1,600, 840 and 336 and the value of 242 × 28 exists 6,776.

Which statement does not describe the data set?
The statement that does not describe the data set 6, 8, 8, 10, 10, 10, 10, 12, 12, 14 is:
(C) The range of the data set is 15.
Consider the data set,
6, 8, 8, 10, 10, 10, 10, 12, 12, 14
The mean of the data set will be:
mean = ( 6 + 8 + 8 + 10 + 10 + 10 + 10 + 12 + 12 + 14 )/ 10
mean = 100/10
mean = 10
The data set in ascending order are:
6, 8, 8, 10, 10, 10, 10, 12, 12, 14
As the number of terms is even. Therefore, the median will be the sum of two middle numbers divided by 2.
So,
Median = ( 10 + 10 )/2 = 20/2 = 10
The mode of a data set is the maximum number of times a number appears in the data set.
Therefore, the mode of the data set is 10.
The range of the data set is the difference between the highest and the lowest number in the data set.
Range = 14 - 6 = 12
The data set is a symmetric distribution if the mean, median, and mode all fall at the same point.
As the mean, median, and mode are 10, 10, and 10 respectively. Hence, the data set is symmetric.
Hence, statements (A), (B), and (D) are true.

Solve using Substitution
9x+10y=1
y=-8
(?,?)
Answer:
x=9,y=8
Step-by-step explanation:
Step 1: Substitute y=-8 into equation 1
9x+10(-8)=1
9x+(-80)=1
9x=1+80
9x=81
Step 2: Divide both sides by the coefficient of x which is 9 then,
x=9
Step 3: Also substitute x=9 into equation 1
9(9)+10y=1
81+10y=1
10y=1-81
10y=-80
Step 4:Divide both sides by 10 then,
y=-8

explain how to expand (x + 3)7 using the binomial theorem.
According to the binomial theorem, the binomial (x + 3)⁷ is equal to the septimic polynomial x⁷ + 21 · x⁶ + 189 · x⁵ + 945 · x⁴ + 2835 · x³ + 5103 · x² + 5103 · x + 2187.
How to expand the power of a binomial by using binomials theorem
Binomial theorem offers a brief form to expand the power of a binomial, that is, an algebraic expression of the form (a + b)ⁿ, where n is a natural number. The complete formula is shown below:
(a + b)ⁿ = Σ {n! / [k! · (n - k)!]} · [tex]a^{n-k}[/tex] · [tex]b^{k}[/tex], for k ∈ {0, 1, 2, ..., n - 1, n}
If we know that a = x, b = 3 and 7, then the expanded form of the power of the binomial is:
(x + 3)⁷ = [7! / (0! · 7!)] · x⁷ · 3⁰ + [7! / (1! · 6!)] · x⁶ · 3 + [7! / (2! · 5!)] · x⁵ · 3² + [7! / (3! · 4!)] · x⁴ · 3³ + [7! / (4! · 3!)] · x³ · 3⁴ + [7! / (5! · 2!)] · x² · 3⁵ + [7! / (6! · 1!)] · x · 3⁶ + [7! / (7! · 0!)] · x⁰ · 3⁷
(x + 3)⁷ = x⁷ + 7 · x⁶ · 3 + 21 · x⁵ · 3² + 35 · x⁴ · 3³ + 35 · x³ · 3⁴ + 21 · x² · 3⁵ + 7 · x · 3⁶ + 3⁷
(x + 3)⁷ = x⁷ + 21 · x⁶ + 189 · x⁵ + 945 · x⁴ + 2835 · x³ + 5103 · x² + 5103 · x + 2187

The value of x in the given diagram is 50°
Calculating angles and values of variablesFrom the question, we are to determine the value of x
From the Vertically opposite angles theorem, we have that vertically opposite angles are congruent.
Thus,
From the given diagram, we can write that
[2(x + 10)]° = (3x - 30)°
Now, we will solve for x
[2(x + 10)]° = (3x - 30)°
2(x + 10)° = (3x - 30)°
2x + 20° = 3x - 30°
20° + 30° = 3x - 2x

Dada una sucesión aritmética, el 75° término, a75 es igual a 556, y el 8° término, a8 es igual a 87. Hallar el valor del 36° término, a36
The value of the 36th term of the arithmetic sequence is 283.
How to calculate the value?It should be noted that an arithmetic sequence illustrate the common difference between the terms.
The following can be deduced from the information:
75th term = a + 74d = 556
8th term = a + 7d = 87
Subtract the equations
(74d - 7d) = 556 - 87
67d = 469
Divide
d = 469/67
d = 7
The first term(a) will be:
a + 7d = 87
Recall d = 7
a + 7(7) = 87
a + 49 = 87
a = 87 - 49
a = 38
Therefore, the 36th term will be:
a + 35d.
a = first term
d = common difference
38 + 35(7)
= 38 + 245
= 283

Answer:
x=-6,8
Step-by-step explanation:
First, let's observe our equation, there is an absolute value (|x|) that means 'x' will have two answers most likely positive and negative.
First we will take off the lines.
now we have
2-2x=14
next minus 2 out of both side of the equation
2 - 2 -2x = 14- 2
-2x =12
now we will divide -2 from both side of the equation
[tex] \frac{ - 2x = 12}{ - 2} [/tex]
we will cancel out - 2
[tex]\frac{x = - 6}{1} [/tex]
x= -6
We aren't done yet since this is an absolute value we have to convert the sum of the equation ( 14) to negatives now which will be in this case (-14)
your new equation will look like this
2-2x= -14
next minus 2 out of both side of the equation
2 - 2 -2x = -14- 2
-2x = - 16
now we will divide -2 from both side of the equation
[tex] \frac{ - 2x = - 16}{ - 2} [/tex]
we will cancel out - 2
[tex] \frac{x = 8}{1} [/tex]
x = 8
Check:x = -6
2 - 2x = 14
2 - 2(-6) = 14.

completes a dive, they reach 14 feet below
the water. What is the distance between the
height of the platform and the depth of the
diver? (Example 3)
The distance between the height of the platform and the depth below water is 47ft . The concept of depth describes how far something extends.
How to calculate depth ?A deep area in a body of water is what the word "DEPTH" means.
Ocean depth is most frequently and quickly measured using sound. Sonar, which stands for sound navigation and range, is a technique that allows ships to map the topography of the ocean below. The instrument uses sound waves to send to the ocean's bottom and time how long it takes for an echo to come back.
Water depth is the distance in feet between the ocean's surface and bottom, as determined by mean lower low water.
Use the following formula for measuring ocean depth.
D = V Times 1/2 T D
Depth (in meters) T= Time (in seconds) V = 1507 m/s (speed of sound in water)

From the equation 4x + 12 = 64, we have that:
a. The problem is: An amount was quadrupled then added by 12, resulting in a final amount of 64.
b. The solution to the equation is x = 13.
c. The solution of x = 13 represents the initial amount.
Context of the equation 4x + 12 = 64The amount x is unknown, hence the problem begins with the unknown amount x.
4x means that the amount was quadrupled.4x + 12 means that 12 was added to the amount.4x + 12 = 64 means that the final amount has a value of 64.Which means that the problem can be summarized as:
An amount was quadrupled then added by 12, resulting in a final amount of 64.
The equation can be solved isolating x as follows:
4x + 12 = 64
4x = 64 - 12
4x = 52
x = 52/4
x = 13.
