Sound requires a medium to travel through (solid, liquid, or gas) and cannot travel through a vacuum.
12.5% of (100 + ?) = 40
20 ×33 + 12 × 23 - 40 ÷ 15-1 + ? = 50
Find the simplified value of the following expression:
62 + 122 × 5 - {272 + 162 - 422}
25.6% of 250 + √? = 119
280 – 70 × 14 ÷ 5 = ? – 21 of 3
16% of 250 + 32% of 500 = ?
(1/8) × (256 × 2)/(8 × 4) + ?3 = 1730
60% of 120 – ?% of 64 = 20% of 200
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
