Answer:
x =7 x = -7 2/3
Step-by-step explanation:
| 3x + 1 | =22
Absolute value equations have 2 solutions, one positive and one negative
3x+1 = 22 3x+1 = -22
Subtract 1 from each side
3x+1-1 =22-1 3x+1-1 = -22-1
3x= 21 3x = -23
Divide each side by 3
3x/3 = 21/3 3x/3 = -23/3
x =7 x = -7 2/3
The sum of Supplementary angle =180 degrees
(2x+3)⁰ +(3x+2)⁰=180⁰
adding like terms
5x+5=180
5x=180-5
5x=175
x=175/5 =35 degrees
so the two angles are :
(2x+3)⁰ =2*35 +3 = 73⁰
(3x+2)⁰=3*35 +2 =105+2 = 107⁰
so correct option is D , 73⁰ and 107⁰
Answer:
Step-by-step explanation:
The area of the base is given by the formula ...
A = πr²
so the radius is ...
r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units
__
The volume is given by ...
V = (1/3)Bh
where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...
V = (1/3)(1386)(21) = 9702 . . . . cubic units
The would be 1 1/4
