70% = 0,7 = 7/10
7/10 * x = 35 | (*10/7)
7/10 * 10/7 * x = 35/1 * 10/7 7/10 * 10/7 => 1
1x = 35/1 * 10 / 7
x = (35*10)/7
x = 350 / 7
x = 50
Download photo-math on ur phone and take a picture of the equation. it should tell u the answer.
Answer:
250 : 500 : 750 : 1000
Step-by-step explanation:
2500 ÷ 1+2+3+4
2500 ÷ 10
250
Therefore the answer is,
1 : 2 : 3 : 4
250 : 500 : 750 : 1000
<em>d = 2r => r = d/2 = 15cm/2 = 7,5 cm</em>
<em />
<em>V = π·r² = 3,14·(7,5)² = 3,14·56,25 = 176,625 ≈ 176,6 cm³</em>
Answer:
