The ratio of 50% content to 25% content is
.. (40-25) : (50-40) = 15:10 = 3:2
There is a total of 5 "ratio units" in this ratio, so each is representing 35 kg/5 = 7 kg of alloy.
21 kg of 50% alloy and 14 kg of 25% alloy should be used.
Answer:
21
Step-by-step explanation:
There are 2 halfs in 1 number.
Lets start with your whole number: 10
You double 10 because there are two halfs in each whole number making it equal 20.
Now you have 3/4
There would be 1 half in this number because it's a fraction and not a whole number.
You would be left over with 1/4
Your answer is 21
Hope this helps! Goodluck
First answer 14^5. Second answer 42^5
Answer:
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
∠B +∠D = 180°
(3x -4)° +(2x -6°) = 180° . . . . substitute given expressions
5x = 190 . . . . . . . . . . . . . . . . divide by °, add 10
x = 38 . . . . . . divide by 5
Then the angle measures are ...
∠B = (3·38 -4)° = 110°
∠D = (2·38 -6)° = 70°
