Step-by-step explanation:
1. The first figure shows triangular prism. The volume of the triangular prism is
The base of this triangular prism is the triangle with the base of 7 cm and height of cm (it is not seen).
The base area is
and the volume of the prism is
Just substitute the length of the height and calculate the volume.
2. The second figure shows square pyramid. The volume of the square pyramid is
The base of this square pyramid is the square with the side length of 4 yd.
The base area is
and the volume of the pyramid is
On Monday he ordered 96
On Wednesday he ordered 264
96 + 264 = 360 total books
24 books in each box
360/24 = 15 boxes....he received 15 boxes of 24 books for a total of 360 books
Answer:
765
Step-by-step explanation:
First, find the number of sophomores
3600 * 3/8 =1350
Use the number of sophomores and multiply by 3/5 to find the amount of sophomores opposed to rock climbing
1350 * 3/5 =810
Then subtract the amount of sophomores from the total amount of students
3600 - 1350 =2250
And multiply the remaining students by 9/10 to find the amount of non-sophomores opposed to rock climbing
2250 * 9/10 =2025
Add the amount of sophomores and non-sophomores opposed to rock climbing
810 + 2025 =2835
The amount of students in favor of rock climbing would be
3600 - 2835 =765
Answer:
I know this is late...but for future reference for others
32 x .60 = 19.2
28 x .40 = 11.2
then add both answers
19.2 + 11.2 = 30.4 average age of the members is your final answer
Step-by-step explanation:
Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.
