Answer:

54

Step-by-step explanation:

Since there are parantheses or however you spell them, by using PEMDAS, we do the parantheses first.

23 - 1 = 22

Now, we do the addition.

22 + 32 = 54

Liono4ka [1.6K]

Step-by-step explanation:

\frac{r}{32}  = \frac{5}{8} =\frac{30}{t}  \\   \\  \therefore \:  \frac{r}{32} = \frac{5}{8} \\  \\  \therefore \:  r =  \frac{32 \times 5}{8} \\  \\\therefore \:  r = 4 \times 5\\  \\ \huge \orange{ \boxed{\therefore \:  r = 20}} \\  \\ \frac{5}{8} =\frac{30}{t}  \\  \\ \therefore \: t =  \frac{8 \times 30}{5} \\  \\ \therefore \: t =  8 \times 6 \\  \\ \huge \purple{ \boxed{ \therefore \: t =  48}}

Answer:

Option (3) will be the answer.

Step-by-step explanation:

Area of a triangle = \frac{1}{2}(\text{Base})\times (\text{Height})

                             = \frac{1}{2}(AB)(CD)

Since, m∠A + m∠B + m∠C = 180°

60° + 60° + m∠C = 180°

m∠C = 180° - 120°

m∠C = 60°

Therefore, ΔABC is an equilateral triangle.

AB ≅ BC ≅ AC ≅12

Sin 60° = \frac{CD}{BC}

\frac{\sqrt{3}}{2}=\frac{CD}{12}

CD = 6√3

Now area of ΔABC = \frac{1}{2}(6\sqrt{3})(12)

                                = 36\sqrt{3}

                                = 62.35

                                ≈ 62.4 square units

Therefore, Option (3) will be the answer.

Answer:

Acceleration equals zero because of constant velocity

f - fr = ma \\ 70 \cos(30)  - fr = 0 \\ 70 \cos(30)  = fr \\  fr \: = 60.62

coefficient

Fr = coefficient × r

60.62= ce ×100

0.60 = coefficient
