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 store manager timed Janette to see how long it would take her to fold and put away a sweater, a shirt, a pair of pants, and a scarf. It took her 26.1 seconds for the shirt, 24.3 seconds for the sweater, 32.8 seconds for the pants, and 18.2 seconds for the scarf. What was the average time it took Janette to fold and put away all four items?
Answers
26.1 + 24.3 + 32.8 + 18.2 = 101.4
101.4 / 4 = 25.35 seconds.
25.35 seconds is the average
26.1+24.3+32.8+18.2=101.4

To simplify fractions, you can either do the prime factorization method, or find the same factors for the simplified numbers.
6/20 = 3/10
3/15 = 3/5
15/20 = 5/6
16/32 = 1/4
21/45 = 7/15.

[tex]3 - \left(y + \frac{1}{2}\right) = 8[/tex]
[tex]3-3 - \left(y + \frac{1}{2}\right) = 8-3[/tex]
[tex]-\left(y + \frac{1}{2}\right) = 5[/tex] <--- Note the negative and the parenthesis
[tex]-y - \frac{1}{2} = 5[/tex] <--- Note how we have -1/2 and not +1/2
[tex]-y - \frac{1}{2}+\frac{1}{2} = 5+\frac{1}{2}[/tex]

[tex]y = -5\frac{1}{2}[/tex]

Jeanie has a 3/4 piece of ribbon. She needs one 3/8 yard piece and a 1/2 yard piece. Can she cut the piece of ribbon into the two smaller pieces? Explain
Answers
[tex] \frac{3}{4} = \frac{6}{8} [/tex] if you multiply the numerator and the denominator for [tex] \frac{3}{4} [/tex] by 2.
She needs [tex] \frac{1}{2} [/tex] yard piece, which is [tex] \frac{4}{8} [/tex] if you multiply the numerator and the denominator for [tex] \frac{1}{2} [/tex].
Now that all the numbers have the same denominator, you can subtract the numerators which is: 6 - 4 - 3 = -1
This means that she cannot cut the ribbon into two smaller pieces.

To find 12 times 13, I double 13 and halve 12 and then multiply
Answers
x12
——-
26
+130
——-
156
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.
