The value of x is 15.8. (one decimal place)

Complementary angles are two angles that add up to a 90-degree angle (a right angle). In other words, if two angles are complementary, the sum of the measures of the angles is 90 degrees. For example, if one angle measures 30 degrees, then its complementary angle measures 60 degrees (since 30 + 60 = 90). Complementary angles are often denoted as "∠A" and "∠B," and they are commonly found in geometry and trigonometry problems.

Two angles are complementary if the sum of the measures is 90°. Therefore, the sum of 2x-9 and 6x-27 must be equal to 90°.

2x-9+6x-27=90

Combine like terms: 8x=126

x=15.8

Therefore, In this case, x is 15.8.

none of the above are true

1. intersect at x=45

so y=sqrt(2)

2. y=cscx period is doubled y=tanx

3. not the same

4. no local maximum of y=secx

minimum point of y=sinx is -1

The ratios do form a proportion.

Explanation: To know whether the ratios form a proportion or not, we can cross multiply them and see if the two products are equal or not. Cross-multiplying the given ratios, we get:$3.5 \times 8 = 14 \times 2$That gives us $28 = 28$, which is true. Therefore, the given ratios do form a proportion. A proportion is an equation that says that two ratios or fractions are equivalent. The four terms in a proportion are called the extremes and means. In a proportion, the product of the means is equal to the product of the extremes. Majority of the explanations for ratio and proportion use fractions. A ratio is a fraction that is expressed as a:b, but a proportion says that two ratios are equal. In this case, a and b can be any two integers. The foundation for understanding the numerous concepts in mathematics and science is provided by the two key notions of ratio and proportion.

You can infer causality from a correlational result, but only when the r value is greater than:

C. 1

Causality refers to a situation in which one event causes another. When there is a correlation between two variables, it means that they tend to move in the same direction.

However, this does not necessarily mean that one event causes the other. In order for a correlation to indicate causality, the correlation coefficient (r) must be greater than 1. If the correlation coefficient is below 1, then there is not enough evidence to suggest that one event causes the other.

In addition, there are other factors that need to be considered when assessing causality from a correlational result.

For example, the strength of the relationship between the variables, the direction of the relationship, and the consistency of the results over time. It is also important to consider the context in which the research was conducted, as this may have an effect on the results.

Answer:

(√3·x - 1)(√3·x + 1)(4x - 3)

Step-by-step explanation:

Note that the last two coefficients are -4 and +3, and the associated factor is (4x - 3).

The first two terms are

12x^3 - 9x^2, which become 3x(4x^2 - 3x) through factoring and then 3x^2(4x - 3).  

Therefore, 12x3 – 9x2 – 4x + 3 can be rewritten as:

                   (4x - 3)(3x^2 - 1).  

It's possible to factor 3x^2 - 1, even though 3 is not a perfect square.  Write 3x^2 - 1 as (√3·x - 1)(√3·x + 1)    

Then 12x3 – 9x2 – 4x + 3 = (√3·x - 1)(√3·x + 1)(4x - 3)

( 3 x2 –  1 )( 1  ⇒ 4x –  3 )

Answer:

white sold = 16

yellow sold = 12

Step-by-step explanation:

w = # of white sold

y = # of yellow sold

w + y = 28   solve this for w

w = 28 - y

9.95w + 13.5y = 321.20     substitute w = 28-y into this expression and solve for y

9.95(28-y) + 13.5y = 321.20

278.60 - 9.95y + 13.50y = 321.20

278.60 + 3.55y = 321.20

3.55y = 321.20 - 278.60 = 42.60

y = 42.60/3.55 = 12   substitute this into w = 28 - y and solve for w

w = 28 - 12 = 16

Step-by-step explanation:

Given

\(\large A\left(-4,-2\right), \large B\left(1,3\right), \large C\left(4,-2\right).\)

The area

The area of a triangle is:

\(Area = \frac{1}{2}|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|\)

So, we have:

\(Area = \frac{1}{2}|-4(3 - -2) + 1(-2 - -2) + 4(-2 - 3)|\)

\(Area = \frac{1}{2}|-4*5 + 1*0 + 4*-5|\)

\(Area = \frac{1}{2}|-40|\)

\(Area = \frac{1}{2}*40\)

Step-by-step explanation:

We do not consider zero to be a positive or negative number. For each positive integer, there is a negative integer, and these integers are called opposites. For example, -3 is the opposite of 3, -21 is the opposite of 21, and 8 is the opposite of -8. ... If an integer is less than zero, we say that its sign is negative

No, Additive inverse of an integer is not always negative.

We can modify the formula to express the total won

Where c1 is the par 5%, C2 the par at 11% and c3 the par at 14%

i1,i2 and i3 the percentage of interest applied to each part

as a total you must use the total earned plus the initial capital

so replacing

the next comes from: the sum of all inverted parts is 8100

so

hitrd equation is from: The amount of money invested at 14% was $500 more than the amounts invested at 5% and 11% combined.

Solution of the equations

we replace the third equation on the second

now replace c3 and c1 on the first equation to find c2

now replace c1 again

The 5 number summary for Roxy's quiz scores is:

Lower Extreme = 75

Lower Quartile = 89

Median = 97

Upper Quartile = 99

Upper Extreme = 100

Sorting the scores in ascending order can help you locate the five-number summary for the provided data set:

75, 88, 90, 96, 98, 100

a. Lower Extreme: The data set's lowest value, which is 75.

b. Lower Quartile (Q1): The midpoint of the data set's bottom half. Since there are six scores, the first three scores—75, 88, and 90—make up the lower half.

The average of the two middle values, 88 and 90, is the subset's median. So, (88 + 90) / 2 = 89 is the Lower Quartile.

Meadin: The middle number in the sorted data set is the median (Q2). Since there are an equal number of scores in the data set in this instance, the median is the average of the two middle values, which are 96 and 98. So, (96 + 98) / 2 = 97 is the median value.

Upper Quartile: The median of the data set's upper half is known as the upper quartile (Q3).

Since there are six points, the final three scores—96, 98, and 100—make up the upper half. The average of the two middle numbers, which are 98 and 100, is the subset's median. So, (98 + 100) / 2 = 99 is the Upper Quartile.

Upper Extreme: The data set's maximum value, which is 100

Answer:

Step-by-step explanation:

salut :

500 000 000= 5× 10^8

650 000= 6,5 ×10^4

58 400 000 000= 5.84 ×10^8

0,000 6= 6×10^-4

0,000 032= 3.2 ×10^-4

0,000 000 072 3= 7.23 × 10^-8

0,000 000 072 3=7,23×10^-7

To find the value of  $$(72\cdot 78\cdot 85\cdot 90\cdot 98)\div (68\cdot 84\cdot 91\cdot 108),$$

we can use the method of cancellation to make the multiplication simpler. Let's cancel out factors common to both the numerator and denominator pairs.

Thus,  \begin{align*}
\(\frac{(72\cdot 78\cdot 85\cdot 90\cdot 98)}{(68\cdot 84\cdot 91\cdot 108)}&=\frac{(2^3\cdot 3^2\cdot 5\cdot 7\cdot 13\cdot 17\cdot 2)}{(2^2\cdot 17\cdot 7\cdot 3\cdot 2^2\cdot 13\cdot 3\cdot 2^3)}\\&=\frac{(2^3\cdot 3^2\cdot 5\cdot 7\cdot 13\cdot 17\cdot 2)}{(2^2\cdot 2^2\cdot 2^3\cdot 3^2\cdot 7\cdot 13\cdot 17)}\\&=\frac{2}{2}\cdot\frac{3}{3}\cdot\frac{5}{1}\cdot\frac{7}{7}\cdot\frac{13}{13}\cdot\frac{17}{17}\cdot\frac{2}{2^2\cdot 2}\cdot\frac{1}{3^2}\\&=\frac{5}{2^2\cdot 3^2}\\&=\frac{5}{36}\)
\end{align*}

Thus, $$(72\cdot 78\cdot 85\cdot 90\cdot 98)\div (68\cdot 84\cdot 91\cdot 108)=\boxed{\frac{5}{36}}.$$The total number of words used is 118.
