What is 12.405 as a mixed number in simplest form
Answers
To express 12.405 as a mixed number in simplest form, the whole number part is 12, and the decimal .405 is equivalent to 405/1000, which simplifies to 81/200, resulting in the mixed number 12 81/200.
Explanation:To express the decimal 12.405 as a mixed number, we first recognize that the number to the left of the decimal point is the whole number part, which is 12. The decimal part is .405, which we need to convert to a fraction. Since .405 has three decimal places, it is equivalent to 405/1000. However, we must simplify this fraction to its simplest form.
We find the greatest common divisor (GCD) of 405 and 1000, which is 5. Dividing both numerator and denominator by 5, we get 81/200. Thus, the mixed number equivalent of 12.405 in simplest form is 12 81/200.
An important note to consider is that when working with significant figures, the number of decimal places in the original number is maintained in the fractional part of the mixed number. Therefore, in a scientific context, the number of significant figures can influence the final result.

It is a commonly used guideline that for the average American child, their maximum adult height will be about twice their height at age 2. Suppose that Micah’s adult height fits the following equation a = 2c – 1, where a represents his adult height and c represents his height at age 2. At age 2 Micah was 35 inches tall. What is Micah’s adult height? Write and solve an equation.
Answers
a=2(35in)-1
a=70-1
a=69in.
The question is about predicting Micah's adult height based on his height at the age of 2. Using the formula a=2c-1 where 'c' is the height at age 2, we substitute 'c' with 35 (his height at age 2) and calculate. Thus, Micah's adult height is predicted to be 69 inches.
Explanation:The question asks about Micah's adult height based on the given equation, a = 2c – 1. In this equation, 'a' represents Micah's adult height and 'c' represents his height at age 2. Given that Micah's height at age 2 ('c') is 35 inches, we can substitute this value into the equation to find Micah's adult height ('a').
So, substituting c=35 into the equation gives us: a = 2*35 - 1. Calculating this results in: a = 70 - 1. Therefore, Micah's adult height is predicted to be 69 inches.

A ship is 2.2° off course. If the ship is traveling at 18.0 miles per hour, how far off course will it be after 5 hours?
Answers
\ |
\ |
\ | y
18 \ |
\ |
\ *|---2.2 °
This is a vector problem. The distance of drift is in x (horizontal axis).
remember that Sin Ф=opposite/hypotenuse. x represents the opposite side form the angle, and 18 is the hypotenuse.
Sin 2.2°=x/18
18 sin 2.2°=x
.691 ≈x
The ship drifts off course .691 miles every hour. .691 x 5 = 5.69 miles after 5 hours.
Final answer:
To determine how far off course a ship will be after 5 hours traveling at 18.0 mph and being 2.2° off course, use the formula: Distance off course = 18.0 mph x 5 hours x sin(2.2°). This results in the ship being approximately 3.45 miles off course after 5 hours.
Explanation:
To calculate how far off course the ship will be after 5 hours, we first need to find the distance the ship travels while off course.
Distance off course = 18.0 mph x 5 hours x sin(2.2°).
Distance off course ≈ 3.45 miles.

Answers
If you add an expression to both sides of an equation, the resulting equation will have the same solution set as the original equation. In other words, they will be equivalent. This is true for all operations. As long both sides are treated the same, the equation will stay balanced.
You will also need to know how to combine like terms. But what are like terms to begin with? Like terms are defined as two terms having the same variable(s) (or lack thereof) and are raised to the same power. In mathematics, something raised to the first power stays the same. So, 5x and 10x are like terms because they both have the same variable and are raised to the first power. You don’t see the exponents because it doesn’t change the value of the terms.
To combine like terms, simplify add the coefficients and keep the common variable(s) and exponent.
The distributive property is another important rule you will need to understand. The distributive property is used mostly for simplifying parentheses in expressions/equations.
For example, how would you get rid of the parentheses here?
6(x + 1)
If there wasn’t an unknown in between the parentheses, you could just add then multiply. That is what the distributive property solves.
The distributive property states that a(b + c) = ab + ac
So, now we can simplify our expression.
6(x + 1) = 6x + 6
Now let's solve the equation you provided.
−(1\4w+8) + 8 = 3
-1\4w - 8 + 8 = 3 <-- Distribute the negative sign
-1\4w = 3 <-- Combine like terms
w = 3 ÷ [tex] -\frac{1}{4}[/tex]
w = -12
So, w is equal to -12.

So first you do the back of 12, 2 times the back of 13, which is 6. Then the back of 12, 2 times the front of 13, which is 2. So you get 26. Then you go to the next line and put a zero, then the same thing as you did with the back of 12, but with the front, which is 1. So 1 times 3 and 1 times 1, so you get 13 and the zero you added earlier, 130. So you get 26 and 130, add them to get 156.
