Answer:
2
Step-by-step explanation:
Initial number = 36
Final number = 63
Change in number = 63 - 36
= 27
Percentage change = (27/36) * 100
= (3/4) * 100
= 3 * 25
= 75 percent
So the percentage change from 36 to 63 is 75%. I hope the procedure for solving is absolutely clear for you to understand. In future you can attempt such problems by following the procedure shown and you will require no further help from outside. Just be careful about the numerator and the denominator.
How are we supposed to answer that
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that On Monday, a museum had 350 visitors while on Tuesday, it had 680 visitors. The percent change in the number of visitors to the museum will then be:
= (680 - 350)/350 × 100
= 330/350 × 100
= 94.29%
The number of people that'll have to visit on Wednesday to have the same estimated percent change will be:
= 680 + (94.29% × 680)
= 680 + (0.9429 × 680)
= 680 + 641
= 1321
Answer:
Step-by-step explanation:
Let the length of the arc of the sector which subtend angle of 30°,2πrx°/360 where x°=30°, this can also be written as πrx°/180 .Perimeter of a sector
2r+ arc length.
Now let the arc length = 22/7 x r x 30/180; this gives, 11r/21cm. Therefore the perimeter = r + r + 11r/21 = 210.
Solving for r in the equation
2r + 11r/21 = 210, multiply through by 21, we now have 42r + 11r = 4410
53r = 4410; divide through by 53, r = 83.2cm. Therefore the length of the arc = 11r/21, 11 x 83.2/21 = 43.6cm.
Check: 2r + 11r/21, 2 x 83.2 + 43.6 = 210cm.
Therefore the radius of the sector
r = 83.2cm.
