Combining like terms, move the one with coefficient a to the left, and move the constant to the right
\dfrac{a}{2} -  \dfrac{2}{3} =a+ \dfrac{1}{5}
\dfrac{a}{2} - a =\dfrac{1}{5} + \dfrac{2}{3}

equalize the denominators in like-terms
\dfrac{a}{2} - \dfrac{2a}{2} =\dfrac{1 \times 3}{5 \times 3} + \dfrac{2 \times 5}{3 \times 5}
\dfrac{a}{2} - \dfrac{2a}{2} =\dfrac{3}{15} + \dfrac{10}{15}

do the operation to the numerators
\dfrac{-a}{2} =\dfrac{13}{15}

solve for a
-a = \dfrac{13}{15} \times 2
-a = \dfrac{26}{15}
a = - \dfrac{26}{15}

How long would it take for a ball dropped from the top of a 100-foot building to hit the ground? Round your answer to two decima
Sunny_sXe [5.5K]

Answer:

time = 2.48 seconds

Step-by-step explanation:

Given data:

distance = 100 foot

Initial velocity = 0 <em>because it was held and being released.</em>

acceleration is gravitational force

<em>gravitational force in feet per second = 32.2 ft/s²</em>

<em>formula for distance is s = ut +(1/2)at² where s = distance , u = intial velocity , a = acceleration and t = time</em>

s = ut +(1/2)at²

100 = 0(t) + (1/2)(32.2)t²

100 = 16.2t²

100/16.2  = t²

therefore t = 2.484

t = 2.48 seconds (to 2 decimal places)

PLEASE HELP!!
RSB [31]

Answer:

D.130°

Step-by-step explanation:

An arc measure ia an angle an arc makes with the circle's centre and is proportional to the angle it subtends to the circumference, arc length.

-Given that  AC and BC are diameters, then \angle AOB =\angle DOC since they are alternate angles.

\angle AOB =\angle dOC=180\textdegree\\\\3x-70=x+10\\\\x=40\textdegree

#Since angles on one side of a diameter sum up to 180°, mBC is calculated as:

(3x-70)+m\angle BC=180\\\\M\angle BC=180+70-3\times 40\\\\=130\textdegree

Hence, mBC=130°
