Răspuns:
100%
Explicație pas cu pas:
Permiteți numărul inițial de fotografii = x
x - 50% din x = x - 0,5x = 0,5x
0,5x + câte% din 0,5x = x
x - 0,5x = y% de 0,5x
0,5x / 0,5x = 1
Prin urmare,
100% = 1
Prin urmare, x trebuie mărit cu 100% pentru a reveni la numărul original.
Answer:
The square root of x will be evaluated first before the addition of 5. Hence (-3)^2 = 9 and 9 +5 = 14, as per your teacher's answer, which is correct. The answer would not be -4.
Answer:
350
Step-by-step explanation:
12% = 0.12
42 / 0.12 = 350
<em>1172. 08 in²</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>A(prism) = 2(lw + lh + wh) - Ab(cylinder)</em>
<em>= 2(16*11 + 16*11 + 11*11) - πr²</em>
<em>= 2(176 + 176 + 121) - 3.14*16</em>
<em>= 2*473 - 50.4</em>
<em>= 946 - 50.24</em>
<em>= 895.76 in²</em>
<em>A(cylinder) = πr² + 2πr*h</em>
<em>= 3.14*16 + 2*3.14*4*9</em>
<em>= 50.24 + 226.08</em>
<em>= 276.32 in²</em>
<em>A(total) = 895.76in² + 276.32in² = 1172.08 in²</em>
<em>Good luck !</em>
