T=1.2d because that is the unit rate which means the elevator travels 1 story every 1.2 seconds.

Round to the near at tenth <br> | 3x + 1 | =22

sdas [7]

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

A cone's height is equal to the radius of its base. The area of its base is 1,386 square units. The approximate radius of the co

maxonik [38]

Answer:

21 units
9702 units³

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

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations)

klemol [59]

Answer:

52 $\pi$

Step-by-step explanation:

The total shaded are will be the area of big circle - not shaded circle + little shaded circle.

The are of big shaded circle: $\pi$ $r^{2}$ So, A= $\pi$ (8^2)= 64 $\pi$

The are of not shaded circle: $\pi r^{2}$ So, A= $\pi$ (4^2)= 16 $\pi$

The are of little shaded cirlce: $\pi r^{2}$ So, A= $\pi$ (2^2)= 4 $\pi$

64 $\pi$ - 16 $\pi$ + 4 $\pi$ = 52 $\pi$
