Answer:
56 because a triangle is always 90 degrees so 90 minus 22 plus 12 equals 56
Step-by-step explanation:
Flip the second fraction and change the fraction into multiplication
Also, change 2 1/2 into a improper fraction
2 1/2 = 5/2
(5/2)/(5/8) becomes 5/2 x 8/5
Multiply across
5 x 8 = 40
------- -----
2 x 5 = 10
Simplify 40/10
40/10 = 4
4 is your answer
hope this helps
Answer:
See the first attachment. The numbers indicate the order 1=least, 5=greatest.
Step-by-step explanation:
This is a calculator exercise. Put the numbers in your calculator and have it tell you the result. Don't forget that (ab)/(cd) = ab/c/d if you don't use parentheses.
See the 2nd and 3rd attachments for the values of the expressions.
___
You can estimate values as follows (top to bottom):
1. 4·9·10^(8-5) ≈ 36·10^3
2. 7·8·10^(5-2) ≈ 56·10^3
3. (7·9)/(8·4)·10^(5-7+2+3) ≈ 2·10^3
4. (8·10)/(8·6)·10^(4+1-11+8) ≈ 1.7·10^2
5. (2·6)/(3·5)·10^(4+3+2-2) ≈ 0.8·10^7
These are crude estimates, but sufficiently close to put the numbers in order as required.
