Answer:
50 % alcohol solution = 10 millimetres
30 % alcohol solution = 90 millimetres
Step-by-step explanation:
two equations can be derived from this question
x + y = 100 equation 1
0.3x + 0.5y = 100 x 0.32 = 32
0.3x + 0.5y = 32 equation 2
where :
x = 30% alcohol solution
y = 50% alcohol solution
multiply equation 1 by 0.3
0.3x + 0.3y = 30 equation 3
subtract equation 3 from 2
0.2y = 2
y = 10
substitute for y in equation 1
x + 10 = 100
x = 100 - 10
x = 90
Answer:
angle d would be 63 degrees since angle B and A would form a same side interior angle, which adds to 180 so angle A has to be 117. angle D also forms a same side interior with angle A, so 180-117=63.
Answer:
2 candies were left.
Step-by-step explanation:
Number of bags of candies = 4 bags
Number of candies in each bag = 18 candies
Total number of candies = 
Ms. Rogers put an equal number of these candies into each of 7 gift boxes.
Divide 72 by 7
72 = 7(10) + 2
Here, remainder is 2.
So,
2 candies were left.
Answer:
The answer to your question is:
12) C
13) AT = 29
Step-by-step explanation:
12)
Data
A (6, -3)
B (-6, 19)
midx = (x1 + x2) / 2 midy = (y1 ´y2) / 2
midx = ( 6 - 6) / 2 midy = (-3 + 19) / 2
midx = 0 / 2 midy = 16 / 2
midx = 0 midy = 8
mid point = (0, 8)
13)
As A is the midpoint of CT then CA = AT
2x - 19 = x + 5
2x - x = 19 + 5
x = 24
AT = 24 + 5
AT = 29
