Is 23 x 10^6 written in scientific notation
No , 23 x 10⁶ is not written in scientific notation.
Values that are either too huge or too little to be conveniently expressed in decimal form can be expressed using scientific notation (typically would result in a long string of digits).
It is also referred to as scientific form, standard index form, and standard form in the UK. This base ten notation is often used by scientists, mathematicians, and engineers because it can make various mathematical procedures easier.Non-zero values are written in the form in scientific notation m × 10ⁿ or where n is an integer and the coefficient m is a non-zero real number, m times ten raised to the power of n. (usually between 1 and 10 in absolute value, and always written as a terminating decimal). The real number m is known as the significand or mantissa, and the integer n is known as the exponent.So 23 x 10⁶ written in exact scientific notation is given by 2.3 × 10⁷ .
Therefore 2.3 × 10⁷ is written in scientific notation whereas 23 x 10⁶ is not in scientific notation.

For the rate, r, for sam to change all the light bulbs in the office building by himself?
One job is involved
3r + 3/8 = 1
3r = 1 - 3/8
r = 1/3 - 3/8÷3
= 1/3 - 3/8 × 1/3

A college accepted new applicants, of whom 56% were male and 44% were female. The board of directors was not pleased that males were being accepted at a greater percentage than females. A private company investigated and found each department accepted a greater percentage of females over males. What may make this claim possible?
Answer:
Simson paradox
Step-by-step explanation:
In Simpson paradox, the trend that appears in the combined data reverses or disappears in the results of the several individual groups that make up the combined data
In the question, given that the percentage of female applicants accepted = 44% while the percentage of male applicants = 56%, and that the private company found that each department accepted a greater percentage of females over males
The above claim can occur when there is a confounding variable, which is the number of applications from female or male
The percentage used or the data provided to by the private company in each department are percentage in proportion of number of accepted females to total number of female applicants and percentage in proportion of number of accepted males to total number of male applicants, whereby, when there are fewer number of female applicants to each department and more were accepted, their percentage will be larger than the percentage of the male applications that have a lower percentage but larger number of applications, such that the accepted male applicants still outnumber the female when that total number of applications are considered.

are 63,360 inches in each mile.
Which of the following values would be an
approximate and appropriate representation of
the distance in inches that Tim calculated?
A. 811,008 inches
B. 811,000 inches
C. 810,000 inches
D. 800,000 inches
Answer:
A
Step-by-step explanation:
the reason for this equations answer to be A is because if you take the inches in one mile 63,360 and multiple it by the miles that it takes to get the school 12.8 you'll get 811,008.

On average, Ethan drinks 3/4 of an 10 ounce glass of water in 2 minutes how many glasses of water does he drink in one hour
Answer:
22.5 glasses of water
Step-by-step explanation:
Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.

Answer:
h(x) = 4x - 1
Step-by-step explanation:
h(x) = f(x) + g(x)

h(x)=5x+2+ (-x-3)
h(x) = 5x+2-x-3
h(x)=5x-x+2-3

Value of sin(x) = 8 / √89, 0 < x < 90.
What are trigonometric functions?Trigonometric functions can be simply defined as the functions of an angle of a triangle where 0 < x < 90°.
Formula used
In right angled triangle ABC , ∠B = 90° , ∠C = x°
cot (x )= ( Base ) / ( perpendicular)
sin ( x) = ( perpendicular ) / ( Hypotenuse )
Pythagoras theorem
(Hypotenuse)² = (Base)² + (perpendicular)²
(AC)² = (AB)² + (BC)²
Given that
cot (x) =5 / 8 , 0< x< 90
Therefore, by comparing the given values of trigonometric function with the formula ,
Base = 5
perpendicular = 8
Substitute the value in the Pythagoras theorem,
(Hypotenuse)² = 5² + 8²
⇒ (Hypotenuse)² = 25 + 64
⇒ Hypotenuse = √89
Therefore,
sin(x) = 8 / √89
Hence Value of sin(x) = 8 / √89, 0 < x < 90

Answer:
A.)
Step-by-step explanation:
the sum of three consecutive even integers is 30 more than the smallest integer. Find the largest integer.
Answer:
10 1/4
Step-by-step explanation:
Assume x as the smallest integer.
Since it is consecutive, you have to add 1 in order to get the next integer.
Equation:
x+x+1+x+2=x+30
x=8 1/4
You need to add 2 to get the largest integer.
So, 8 1/4 + 2 = 10 1/4
In ΔBCD, \overline{BD} BD is extended through point D to point E, \text{m}\angle CDE = (9x-12)^{\circ}m∠CDE=(9x−12) ∘ , \text{m}\angle BCD = (2x+3)^{\circ}m∠BCD=(2x+3) ∘ , and \text{m}\angle DBC = (3x+5)^{\circ}m∠DBC=(3x+5) ∘ . Find \text{m}\angle BCD.M∠BCD.
Answer:
Angle BCD is 13 degrees
Step-by-step explanation:
Here, we want to find the measure of angle BCD
To get this, we need an appropriate diagram. The diagram can be seen in the attachment.
To find the value of BCD, we can use an important triangle theorem.
This is that the sum of opposite interior angles of a triangle equals the exterior angle.
Thus, we have that;
BCD + DBC = CDE
hence;
3x + 5 + 2x + 3 = 9x-12
5x + 8 = 9x -12
9x-5x = 8 + 12
4x = 20
x = 20/4
x = 5
So the measure of BCD will be 2(5) + 3 = 10 + 3 = 13

Answer:
2,796.
Step-by-step explanation:
First, I added 619 + 313, which is 932. Since she is able to use more, I multiplied it by two to get me 1,864. If I tried multiplying it by three, I would get 2,796, which is a perfect amount.
