Answer:
1:4
Step-by-step explanation:
Given
Volume of orange juice = 50ml
Volume of water = 200mL
Required
Ratio of volume of orange juice to water
Ratio = volume of orange juice/volume of water
Ratio =50mL/200mL
Ratio =5/20
Ratio =1/4 or 1:4
Hence the required ratio is 1:4
Quadratic formula: (-b +/- sqrt(b^2 - 4ac)) / 2a
a = 10
b = -1
c = 9
1 +/- sqrt((-1)^2 - 4(10)(9)) / 2(10)
1 +/- sqrt(1 - 360) / 20
x = 1 +/- sqrt(359i) / 20
Hope this helps!
2x + y = 8
x - y = 10
--------------add
3x = 18
x = 6
x - y = 10
6 - y = 10
-y = 10 - 6
-y = 4
y = -4
solution is : (6,-4)
SAS stand for side-angle-side. In order to know that these two triangles are similar you need to find the measure of side GH and MN
To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R
7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5
Angle R = 12x + 20
12(5) + 20
60 + 20
80
Option C is your answer.
