U just x it to the tingles
Answer:
The number is 4321
Step-by-step explanation:
Let the number be x
16 2/3% = (16x3+2)/3 % = 50/3 %
50/3 % of X = 72
50/300 x X =72
X=(72 x 300)/50
X=21600/50
X=4321
You would subtract x from each side. It would then be 3y=-x-15. Then you would divide all of the equation by 3. Your final answer would be y=-3x-5.

Actually Welcome to the Concept of the Surface Areas and Volumes.
Since, Volume of cone = 1/3 π r^2 h,
here, r = 10 Inches and h= 12 inches, also π =3.14
so, VOC = 1/3 π (10)^2 × (20)
VOC = 1/3(3.14)(100)(20)= 2093.33 inch^3
=> so the volume of the cone is 2093.33 cubic inches.
Answer:
Using the Sine Rule , which states that

In Δ ABC
∠A +∠B+∠C=180°→→Angle Sum Property of Triangle
72°+85°+∠C=180°
∠C=180° - 157°
∠C= 23°
All the angles are in degrees.

Using the table of Sine, Calculating Sine Values
Sin 72°= 0.9510
Sin 85°=0.996
Sin 23°=0.390

Among the five Options,
Option E: a= 15.09 and b=15.81 is approximately true.
