Answer:
Mean of City A is 3.6. Mean of City B is 4.6.
Step-by-step explanation:
To find the mean of a data set you add all the numbers in the data set and then divide your answer by how many numbers are in the data set.
Answer:
22.25 ft long
if you add 10.5 with 11.75 you'll get 22.25
Answer:
Myron received 40% votes.
Step-by-step explanation:
Myron receives 10 votes from his class of 25 students and we have to calculate the percentage of the vote received.
Now we will use unitary method to calculate the percentage.
∵ Out of 25 students Myron received votes of = 10 students
∴ Out of 1 student Myron received votes = 10/25 students
∴ Out of 100 students Myron received votes = 10×100/25 = 40%
Myron received 40% votes.
Answer:
11 pages with picture to every nine pages without pictures. or 11 per every 9
Step-by-step explanation:
divide each number by a common denominator, in this case 5, to get a change from 55 per every 45 to 11 per every 9.
19. 4/6 or 2/3 (lowest term) or 2:3 in ratio
20. 2/3 or 2:3 in ratio
21. 5/12 or 5:12 in ratio
22. 14
To get geometric mean, multiply the numbers then get the square root of the product (if there are two numbers), cube root (if there are three numbers), and so on. In this case, 7*28 = 196; √196 = 14
23. 10 ft : 2.5 ft.
Convert the values so that it will be similar. In this case, 30 inches is converted to ft.
24. 24 is the Perimeter of ABCDE.
ABCDE and FGHJK are similar shapes. Similar shapes have proportional measurements.
Now compute for the sides of ABCDE.
AB = 4; BC = ?; CD = ?; DE = ?; EA = ?
AB + BC + CD + DE + EA
4 + 4 + 5 + 6 + 5 = 24
Find BC:
AB/BC = FG/GH
4/BC = 8/8
8BC = 32
BC = 4
Find CD:
BC/CD = GH/HJ
4/CD = 8/10
8CD = 40
CD = 5
Find DE:
CD/DE = HJ/JK
5/DE = 10/12
10DE = 60
DE = 6
Find EA
DE/EA = JK/KF
6/EA = 12/10
12EA = 60
EA = 5
