x=7
Step-by-step explanation:
The number of shelves stephen can make is approximately 27
<h3><u>Solution:</u></h3>
Given that Stephen makes wooden shelves for his room
Stephen wants to make the shelves 3/4 foot long
He starts with a board that is 20 feet long
To find: number of shelves he can make
So the number of shelves stephen can make can make is found out by dividing 20 feet long board by 3/4 foot long
So the number of shelves stephen can make is approximately 27
Answer:
1/4, 2/5, 1/2, 3/5, 2/3, 13/18, 7/9, 5/6, 2 6/15, 2 4/9, 2 3/5, 2 2/3, 6 3/8, 6 1/2,
6 3/4, 6 5/6
Step-by-step explanation:
I like to organize decimals more than fractions because it's easier for me, so I'm changing each of them to a decimal. You don't have to do this though.
- To change a fraction to a decimal, if it is simplified, make it an improper fraction
- Then, divide the numerator from the denominator. For example, 1/4 = 0.25 because 1 divided by 4 = 0.25
- 3/5 = <u>0.60</u>,
- 1/4 = <u>0.25,</u>
- 1/2 = <u>0.50</u>,
- 2/5 = <u>0.40</u>,
- 7/9 = 0.7 repeating or just <u>0.78 </u>rounded,
- 13/18 = 0.72 repeating or <u>0.73</u> rounded,
- 5/6 = 0.83 repeating or <u>0.84 </u>rounded,
- 2/3 = 0.66 repeating or <u>0.67</u> simplified,
- 6 3/4 = 27/4 or <u>6.75</u>,
- 6 1/2 = 13/2 = <u>6.50,</u>
- 6 5/6 = 41/6 = 6.83 repeating or <u>6.84</u>
- 6 3/8 = 51/8 = 6.375 or <u>6.38</u>
- 2 2/3 = 8/3 = 2.66 repeating or <u>2.67</u>
- 2 6/15 = 36/15 = <u>2.40</u>
- 2 3/5 = 13/5 = <u>2.60</u>
- 2 4/9 = 22/9 = 2.44 repeating or <u>2.45</u>

Ordering them is pretty easy, just start from the smallest and move to the greatest!
- 0.25 = 1/4
- 0.40 = 2/5
- 0.50 = 1/2
- 0.60 = 3/5
- 0.67 = 2/3
- 0.73 = 13/18
- 0.78 = 7/9
- 0.84 = 5/6
- 2.40 = 2 6/15
- 2.45 = 2 4/9
- 2.60 = 2 3/5
- 2.67 = 2 2/3
- 6.38 = 6 3/8
- 6.50 = 6 1/2
- 6.75 = 6 3/4
- 6.84 = 6 5/6
Independent. A dependent variable would be a letter or symbol that needs a letter or key to be solved.
Answer:
14.6
Step-by-step explanation:
We solve using the Trigonometric function Cosine
cos θ = Adjacent/Hypotenuse
θ = 40°
Hypotenuse = 19
Adjacent = x
Therefore,
cos 40 = x/19
Cross Multiply
x = cos 40 × 19
x = 14.554844419
Approximately to the nearest tenth,
x = 14.6
