The answer would be 5 to 9. There are nine marbles overall and there are five white marbles. If you put the overall number of marbles second and the amount of that color of marbles first, you get D.
No, answer would be 2 because -9/3 is -3 and -3 plus 2 is -1
Answer:
Option B and Option D are the two answers
1500 x 12% = 180mL
To get this answer, you have to multiply the 1500mL by 12% (0.12) and get 180. This means that 12% of your 1500mL solution will be 180mL of hydrochloric acid.
Answer:
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Step-by-step explanation:
Given:
Hypotenuse BD = 12 unit
Angle θ = 30°
Find:
Perimeter of rectangle ABCD
Computation:
Using trigonometry function
Sin θ = Perpendicular / Hypotenuse
Sin 30 = CD / BD
0.5 = CD / 12
Length of CD = 6 unit
Cos θ = Base / Hypotenuse
Sin 30 = BC / BD
0.866 = BC / 12
Length of BC = 10.4 unit
Perimeter of rectangle ABCD = 2[Length + Width]
Perimeter of rectangle ABCD = 2[6 + 10.4]
Perimeter of rectangle ABCD = 2[16.4]
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
