Salutations!

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.

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

Jeanie cannot cut the piece of ribbon into two smaller pieces. 

[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.

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

The Average, or the mean of the times, is the sum of the times divided by the number of times. 

26.1 + 24.3 + 32.8 + 18.2 = 101.4
101.4 / 4 = 25.35 seconds.

25.35 seconds is the average
25.35 seconds. 
26.1+24.3+32.8+18.2=101.4
101.4/4 (the number of items)=25.35 per each item

36 is 75% of what number

Answers

The answer should be 48

The percentage is the method of distributing the numbers in a range from 0 to 100. The number 36 is 75% of 48.

To find the number that 36 is 75% off, use the following steps:

Remember that per cent means "per hundred." So, 75% can be written as the fraction 75/100 or the decimal 0.75.

Let's call the unknown number "x". We want to find the value of "x" that satisfies the equation: 36 = 0.75 * x.

To solve for "x", we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.75.

36 / 0.75 = (0.75 * x) / 0.75

Simplifying the right side, we get:

36 / 0.75 = x

Evaluating the left side of the equation, we have:

48 = x

Therefore, 36 is 75% of 48.

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=2c-1
a=2(35in)-1
a=70-1
a=69in.
Final answer:

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.

How do I do this (Comes With Picture) if someone could help me with this that would be amazing :)

Answers

The error occurs in step 3. The student did not distribute the negative properly to every term inside the parenthesis. Below is one proper way to solve for y

[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]

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

So the proper final answer is [tex]y = -5\frac{1}{2}[/tex]
(this is a mixed number which converts to the decimal number -5.5)


To find 12 times 13, I double 13 and halve 12 and then multiply

Answers

No just multiply them 12 times 12 is 144 just add 12 so it could be 12 times 13 and it would be 156
13
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.
