Answer:
15,000cm^3
Step-by-step explanation:
Dividing the solid into 2;
Volume = Volume of A + Volume of B
Volume of Top prism (A) =25cm * 20cm * 10cm
Volume of Top prism (A) = 5000cm^3
Volume of bottom prism B = 20cm * 50 * 10
Volume of bottom prism B = = 10000cm^3
Volume of the figure = 5000 + 10000
Volume of the figure = 15,000cm^3
Answer:
x=4.5 and y= -6
Step-by-step explanation:
2x+5y= -21
-2x+3y= -27
add the two equations: 8y= -48
y=-48/8= -6
sub for y in 2x+5y= -21
2x + 5(-6)=-21, 2x-30= -21
2x= -21+30= 9
x= 9/2=4.5
Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
<h3>How to calculate greater mean number of pages?</h3>
From the complete information, we can deduce that the number of each pile of book is given as follows:
<u>For pile W;</u>
Red books = 10 × 5 = 50 red books.
Blue books = 5 × 5 = 25 blue books.
Therefore, total books in pile W = 50 + 25 = 75 books.
Mathematically, the mean for each pile can be calculated by using the following formula:
Mean = [F(x)]/n
Mean = 75/10
Mean = 7.5.
<u>For pile Y;</u>
Red books = 10 × 5 = 50 red books.
Mean = [F(x)]/n
Mean = 50/5
Mean = 10.
In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
