Answer:
$180 was collected from Grade 9 students
Step-by-step explanation:
40% of 120 students is 48. This means that 48 students went. If half of these students paid half price, 24 students paid $2.50, and 24 students paid $5.00.
24 x 2.5 is 60
24 x 5 is 120
60 + 120 is 180, which is the total amount of money collected.
Answer:
50 degrees.
Step-by-step explanation:
Angle FGE = because angles on a straight line add up to 180 degrees.
Angle EFG = (Angles in a triangle add up to 180)
Add 20 to both sides:
Subtract 6x from both sides:
Angle
Answer:
Minimum: 50
Lower Quartile: 59
Median: 66
Upper Quartile: 74
Maximum: 92
Step-by-step explanation:
50, 55, 58, 60, 62, 64, 68, 70, 72, 76, 84, 92
Minimum: 50
Lower Quartile: (58 + 60)/2 = 59
Median: (64 + 68)/2 = 66
Upper Quartile: (72 + 76)/2 = 74
Maximum: 92
Answer:
a) 4:13
b) 9:13
Step-by-step explanation:
Hello! To solve this question, we can write and solve a proportion. Because we are looking for the whole, which is the total amount of visitors on a Saturday, set the proportion up like this: 144/x = 60/100. This is because we are looking for the total amount of visitors, and we know that 144 is 60% of x number of visitors. Cross multiply the values in order to get 14,400 = 60x. Now, divide each side by 60 to isolate the "x". 14,400/60 is 240. x = 240. The art museum had 240 visitors that Saturday.
