Answer:
C. 135
Step-by-step explanation:
21×16=336
pi×8^2=201
336-201=135
Total number of cans that need to be collected = 325
Number of cans collected in first week = 135
Number of cans collected in the second week = 89
The number of cans collected in third week = c
Then the inequality equation will be
135 + 89 + c = 325
224 + c = 325
c = 325 - 224
= 101
So at least 101 cans are required to meet the goal and more that 101 cans will surpass the goal.
The main floor has 26 rows of 29 seats each, that is 26*29 = 754 seats
And in the balcony there is 8 rolls of 23 seats, that is 8*23 = 184 seats
So the difference is 754 - 184 = 570
Then the main floor has 570 seat more than the balcony
Answer:
16
Step-by-step explanation:
The ratio fo the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
In a 30-60-90 triangle, the length of the short leg is the length of the long leg divided by sqrt(3).
The length of the short leg is 8 cm.
The length of the hypotenuse is twice the length of the short leg.
g = 2 * 8 cm = 16 cm
