Answer:   330⁰

<u>Step-by-step explanation:</u>

Circumference (C) = 2π · radius(r)

                          12 = 2π·r

                     \dfrac{6}{\pi}=r

Arc length (s) = radius(r) · θ           <em>(reminder that theta is in radians)</em>

                  11=\dfrac{6}{\pi}\cdot \theta\\

                  \dfrac{11\pi}{6}=\theta

To convert radians to degrees, use the proportion:   π = 180⁰  

\dfrac{\pi}{180}=\dfrac{11\pi}{6x}\\\\6x(\pi)=180(11\pi)\\\\x=\dfrac{180(11\pi)}{6\pi}\\\\x=30(11)\\\\x=330

PLEEEEEEEAAAAAAAAAASSSSSSSSSEEEEEEE a wee this quickly<br>How did he get answer A
Simora [160]

Answer:

To get answer A,  Dave took 47*5 = 235

Step-by-step explanation:

There are 147 containers that contain 5 gallons each.  We need to multiply to find the total number of gallons.

total number of gallons = containers * number of gallons per container

                                       = 147* 5 gallons per container

                                        =735 gallons

To get answer A,  Dave took 47*5 = 235

Please Help !!Mr. Mudd gives each of his children $2000 to invest as part of a friendly family competition. The competition will
VikaD [51]

Answer:

Albert = $2159.07; Marie = $2244.99; Hans = $2188.35; Max = $2147.40

Marie is $10 000 richer

Step-by-step explanation:

Albert

(a) $1000 at 1.2 % compounded monthly

A = P\left(1 + \dfrac{r}{n}\right)^{nt}

A = 1000(1 + 0.001)¹²⁰ = $1127.43

(b) $500 losing 2%

0.98 × 500 = $490

(c) $500 compounded continuously at 0.8%

\begin{array}{rcl}A & = & Pe^{rt}\\& = & 500e^{0.008 \times 10}\\& = &\mathbf{\$541.64}\\\end{array}\\

(d) Balance

Total = 1127.43 + 490.00+ 541.64 = $2159.07

Marie

(a) 1500 at 1.4 % compounded quarterly

A = 1500(1 + 0.0035)⁴⁰ = $1724.99

(b) $500 gaining 4 %

1.04 × 500 = $520.00

(c) Balance

Total = 1724.99 + 520.00 = $2244.99

Hans

$2000 compounded continuously at 0.9 %

\begin{array}{rcl}A& = &2000e^{0.009 \times 10}\\& = &\mathbf{\$2188.35}\\\end{array}\\

Max

(a) $1000 decreasing exponentially at 0.5 % annually

A = 1000(1 - 0.005)¹⁰= $951.11

(b) $1000 at 1.8 % compounded biannually

A = 1000(1 + 0.009)²⁰ = $1196.29

(c) Balance

Total = 951.11 + 1196.29 = $2147.40

Marie is $ 10 000 richer at the end of the competition.
