Answer:
Let the angles have measures 2x,3x,4x
Then 2x+3x+4x = 180
and the rest is easy
Step-by-step explanation:
14. sometimes, you can have a 45-45-90 or 60-30-90 triangle (degrees)
sometimes true
15. always
16. never, paralellogram has 2 pairs of paralell sides, trapezoid has 1
17.always
18. sometimes
19. always
20. always
You can use proportions.
22.5/100 = 18/x
cross multiply:
100 x 18 = 1800
1800/22.5 = 80
so now you know 80 is the 100%.
then do:
37.5/100 = x/80
cross multiply:
37.5 x 80 = 3000
3000/100 = 30
37.5% = 30
Answer:
0.18 miles per minute.
Step-by-step explanation:
You need to divide 9/10 miles by 5 because 5 minutes/5=1 minute.
9/10/5=0.18 (or 18/100)
Answer:
3
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
9/3 = 3
The common ratio is 3
