The answer is 3.75 cm^3.
First you have to change 12 mm to cm, which would be 1.2 cm. The formula for the volume of a triangular prism is 1/2 x a x c x h. So, 1/2 (2.5) x (1.2) x (2.5) = 3.75 cm^3
Answer:
16m/s
Step-by-step explanation:
distance travelled from L to M = 6 x 10 = 60m
distance travelled from M to N = 160 - 60 = 100m
time taken to travel from M to N = 100/25 = 4 seconds
average speed = total distance / total time = 160m / (6 + 4) seconds = 16m/s
hope that helps!
this is a question on speed, distance and time. I have a formula for it up in my insta page (learntionary) if you need it :)

Answer: Choice A) 0.20</h3>
===================================================
Explanation:
Let's say there are 1000 students. The students must take math, science or they can take both simultaneously.
- 65% of them are in math. So there are 0.65*1000 = 650 math students.
- 43% are in science, leading to 0.43*1000 = 430 science students.
- 13% are in both so we have 0.13*1000 = 130 students who are in both.
Now onto the sentence that says "Suppose a high school student who is enrolled in a math class is selected at random"
This means we only focus on the 650 math students and ignore the 1000-650 = 350 students who aren't in math.
Of those 650 math students, 130 are also in science (since 130 are in both classes).
The probability we're after is therefore 130/650 = 0.20
