It would be 23 girls if you divide 46 by 2 since your trying to figure out the amount of boys for 46 girls.
All cross sections of spheres are “circles”
951hz divide by 343m/s = <span>2.77259475
times the answer by 99hz = </span><span>274.48688
to 1 d.p is 274.5m/s</span>
14 red 8 blue
88/4 =22
22-14 = 8
I think this if correct
<span>7(B + 3) + 2B
= 7B + 21 + 2B
= 9B + 21
hope it helps</span>
