To find the area of the square base, you will use the information given about the area of the lateral side to find the missing base length.
First, divide the total lateral area by 4 because there are 4 congruent lateral faces.
107.25/4 = 26.8125
Use this in the formula for area of a triangle.
A = 1/2 x b x h
26.8125 = 1/2 x b x 8.25
26.8125 = 4.125b
b = 6.5 cm
The length of the base edge is 6.5 centimeters.
Answer and Step-by-step explanation:
The calculation of cumulative frequency distribution is shown below:-
Daily low temperature Frequency cumulative frequency
35-39 3 3
40-44 2 3 + 2 = 5
45-49 5 5 + 5 = 25
50-54 12 25 + 12 = 37
65-69 6 37 + 6 = 43
55-59 8 43 + 8 = 51
60-64 1 51 + 1 = 52
We simply applied the above format
Answer:
37i-16
Step-by-step explanation:
(4+7i)(3+4i)
12+21i+16i+28i^2
12+37i+28(-1)
37i+12-28
37i-16
Answer:
The call lasted for 47 minutes.
Step-by-step explanation:
It is given that:
Value of prepaid card = $25
Cost per minute of long distance call = 24 cents = $0.24
Remaining credit = $13.72
Let,
x be the number of minutes
y be the remaining amount
y = 25 - 0.24x
13.72 = 25 - 0.24x
0.24x = 25 - 13.72
0.24x = 11.28
Dividing both sides by 0.24
Therefore,
The call lasted for 47 minutes.
The answer is 3 cm.
Circle A's diameter is 27, right? However, circle A is 3 times the value of the area of B. Because of that, you need to do 27/3, the inverse, in order to get the diameter of circle B.
Next, because radius is half of the diameter, you do 9 divided by 3 or 9 times 1/2.
