Answer:
D 13
Step-by-step explanation: L+L+W+W=Perimeter
2(1/4x)+2(2x+1)=4.5x+2
4.5x+2=29 Subtract 2
4.5x=27 Divide by 4.5
x=6 1/4(6)= 1.5 W=1.5 1.5(2)=3
2(6)+1=13 13(2)=26
26+3=29inches perimeter
Answer:
14 days
Step-by-step explanation:
5x2=10
140÷10=14
Answer: a= 144. b= 67
Step-by-step explanation:
Angle b and the angle of measure 113 are same side interior angles which sum to 180 (When 2 parallel lines are cut by a transversal, special angles are formed)
113+b=180. Subtract 113 from both sides.
b= 67 degrees
Now that you have b, the interior angles of four sided figures sum to 360.
a+113+67+36=360. Combine like terms.
a+216=360. Subtract 216 from both sides.
a= 144 degrees
The number is: " -3 " .

Let "x" be the "unknown number" for which we are to solve.
8x − (-54/9) = -18 ; Solve for "x" ;
→ 8x − (-6) = - 18 ;
→ 8x + 6 = - 18 ;
Subtract "6" from each side of the equation:
→ 8x + 6 − 6 = - 18 <span>− 6 ;
to get: 8x = -24 ;
Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ;
8x / 8 = -24 / 8 ;
to get: x = -3 .

Answer:
224 in^3
Step-by-step explanation:
The foruma appropriate to the calculation of the cone's volume is ...
V = (1/3)Bh
where B represents the area of the base and h represents the height.
For your numbers, this is ...
V = (1/3)·(48 in^2)(14 in) = (16 in^2)(14 in) = 224 in^3
