Answer:
No
Step-by-step explanation:
pretend that the larger number in the ratio is always 60
10:8 so 10=60
60÷10 =6
6x8=48
so in 10:8 10=60 and 8=48
60-48= 12
in 5:2
5=30
2=12
30-12=18
10:8 and 5:2 when substituted to a real number will not have the same difference so they are not a proportion
By estimation, 3.9 turns into 4 and 5.3 turns into 5. The answer after estimation is 20 while the real answer is 20.67. Well u see by estimation we get an answer of two places right. So, real answer should also have two places.Place the decimal point after it.y43
Step-by-step explanation: i dont know if I'm right or not
When you have something like say log, no base given, like log₃ or log₆ or log₉, then the base 10 is implied, so a "bare" log, really means log<span>₁₀

Answer:
100°
Step-by-step explanation:
The relevant relation for angle x is ...
x = (AB +DE)/2
and for angle y, it is ...
y =(AC -DE)/2
Using the second relation to write an expression for DE, we have ...
DE = AC -2y
In the first equation, this lets us write ...
x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2
2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2
(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3
AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values
AC = 100°
