Answer:
Sessions needed= 12
Step-by-step explanation:
Giving the following information:
Total hours= 12 hours
Practice= 3/4= 0.75 of an hour
Already practiced= 3 hours
<u>First, we need to determine how many minutes does she practice each session:</u>
Minutes per session= 0.75*60= 45 minutes
<u>Now, we divide the total practice in minutes required for the minutes per session:</u>
Sessions needed= (9*60) / 45
Sessions needed= 12
Answer:
5430.85 square feet
Step-by-step explanation:
Height of the cylindrical part of the cilo = 25 feet
radius of the base cylindrical part of cilo = 8 feet
Now volume of cylindrical part of cilo =
Volume of cylindrical part of cilo = 
= 
Now,
Height of the conical part of cilo = 6 feet
Radius of the conical part of cilo = 8 feet
Volume of the conical part of cilo = 
= 
Volume of the entire cilo = 
since 
volume of entire cilo = 
= 5430.85
Answer:
x=5
Step-by-step explanation:
5x-2=23
add 2 to both sides
5x=25
divide by 5 on both sides
x=5
To find the average speed in miles per hour, you can find the number of miles Khalil traveled per minute and then multiply that by 60 to convert it to hours.
54 miles/45 minutes = 1.2 miles per minute
1.2 x 60 = 72 miles per hour.
Khalil traveled at an average speed of 72 miles per hour.
Step-by-step explanation:
y=-1/2.x+2 =-2 then x=8
the area is S = 
S=121/4
