Answer:
30 students
Step-by-step explanation:
Yesterday: 1/3 of the 75 students (75 / 3) = 25 students
There are now 50 students remaining to give their speeches.
Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students
50 - 20 = 30 students remaining to give their speeches.
Volume of square pyramid = a^2 x h/3
Volume of pyramid A = 9^2 x 10/3
Volume of pyramid A = 270 cubic inches.
Divide volume of B by A:
1350/270 = 5
5 x 100 = 500 % bigger
To check, rewrite 500% as a decimal and multiply by the volume of A:
500%/100 =5
270 x 5 = 1350
This equals the volume of B, so the scale was calculated correctly.
8.76 + (–3.05)
