Answer:
120 km^3
Step-by-step explanation:
the base is a right triangle
A = (leg1 x leg2)/2 = (6 x 8)/2 = 24 km^2
the volume of a prism is base area x height
V = 24 x 5 = 120 km^3

Step-by-step explanation:
if you divide 15000 and 2 you get 7500.and if you get 7500 you have to multiply to check if its correct so 7500 times 2 equals 15000. So the answer is 7500.
Answer:
Option A
Step-by-step explanation:
To balance the silver at the exactly correct concentration, the first step is to focus only on the silver content in each bullion. This means that we can multiply the total weight of each piece by its concentration, to find the exact amount of silver inside. So, for instance, the target is 1800g of 0.9 sterling silver, and 0.9*1800=1620 g of silver. Now we can test A, B, and C to see if they contain that amount. In A, 450*0.75+1350*0.95=1620, which is a match! I tested the other two options, and neither of them had the correct amount of silver. Therefore, the answer is option A. Hope this helps!
Answer:
Age of Raju = 12
Age of Ravi = 16
Step-by-step explanation:
Let the Ages of Raju and Ravi be 3x and 4x years
According to question, =
⇒ 5(3x+4)=4(4x+4)
⇒ 15x+20 = 16x+16
⇒ 15x−16x=16 - 20
⇒ −x = −4
⇒ x = 4
Age of Raju = 3 × 4 = 12
Age of Ravi = 4 × 4 = 16
