The complete exercise is: "Which arrangement shows
, 3.7,
, and 3.89 in order from least to greatest?"</h3><h3>
</h3>
Convert from mixed numbers to decimal numbers.
The steps to do this, are the following:
1. You must divide the numerator of the fraction by the denominator.
2. Then you must add the quotient obtained to the whole number part.
Applying this procedure, you get that:


Now that you have all the numbers in decimal form, you can order from least to greatest:

Therefore, you can conclude that the correct arrangement is:

Answer:
(?)=70
Step-by-step explanation:
A triangle has 180 degrees. You can find the total sum of the ratio by adding its parts together 1+3+5 = 9 Now to find out what each part of the ratio is worth we divide the whole value (180) by the sum of the ratio parts (9)
180/9 = 20
Now we multiply each part of the ratio by 20
1 * 20 = 20
3 * 20 = 60
5 * 20 = 100
Since we have an angle greater than 90 degrees this is an obtuse triangle.
Answer:
46
Step-by-step explanation:
