Here is your answer
Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.
Answer:
the required postulate which should be used here to make the triangles congruent is
C. ASA , okay
Step-by-step explanation:
because, one side and one angle of both triangles are equal and one of angles of the both triangles are vertically opposite angles , hence they are also equal , so we get an angle, a side and one another angle equal to corresponding side and angles of other triangles , so required postulate is C. ASA

79.30 ---- 100%
The while store is discounted by 12% So subract 12 from 100
100-12 = 98
We have to figure out what 88% is
79.30 ---- 100%
X ------------ 88%
Cross Multiply
79.3× 88 = 100x
6978.4 = 100X
69.784 is without taxes
69.784 = 100% {100% because it is the total price.}
69.784 = 100%
X --------- 6.25%
Cross Multiply
69.784 × 6.25 = 100X
436.15 = 100 X
X = 4.3615
69.784 + 4.3615
74.15 is the answer
Answer: Non of the option.
Step-by-step explanation:
The given equation is
4x^3 - 6x^2 + 15x + 2 = 0
Let's test 1, if it's one of the root. I.e
If x = 1
4 - 6 + 15 + 2 = 15
Positive 1 is not a root to the equation
If x = - 1
-4 - 6 - 15 + 2 = - 23
Negative 1 is not a root
If x = 2
4x8 - 6×4 + 15×4 + 2
32 - 24 + 30 + 2 = 40
Positive 2 is not a root
If x = - 2
4×(-8) - 6×4 - 15×2 + 2
-32 - 24 - 30 + 2 = -84
Negative 2 is not a root
If x = 3
4×27 - 6×9 + 15×3 + 2
108 - 54 + 45 + 2 = 101
Since non of them tend to zero, non of the option is a root of the equation
The answer is d because the line is cutting thru the x axis on 1/3 and then the line cuts thru the y axis on -2 so the answer would be 1/3x-2
