1/-x*5y/-8
-1/x × (-5y/8)
5y/8x
Answer:
Step-by-step explanation:
Area of Circle can be calculated using following formula
Where r is radius of circle
<u>Area of outer circle (r=11 yd)</u>
<u>Area of inner circle (r=8 yd)</u>
Area of shaded region
If x is the time, in hours, then:
x(55)=x(50)+15
5x=15
x=3 hours before Aisha is ahead of Luke
hope this helps you!
The hydronium ion is H₃O⁺ and its concentration is equivalent to the H⁺ ion concentration. The H⁺ ion concentration is given by:
pH = -log[H⁺]
[H⁺] = 10^(-8.2)
[H⁺] = 6.31 x 10⁻⁹ mole/dm³
The hydronium ion concentration is 6.31 x 10⁻⁹ mole/dm³
<span>Since RT bisects QS, we have QT congruent to ST. Bisect means it cuts QS in half. The we have RT congruent to RT since it is the same. By SSS, we have triangle QRT congruent to triangle SRT since QT is congruent to ST, RT is congruent to RT, and QR is congruent to SR. Each side is congruent to its respective side in the other triangle and that is SSS (side, side, side).</span>
