Average velocity = distance / time
=(0-25) / (6-3)
= -8.3 answer
The answer is 180ft squared. I got this when I used the formula 1/2 times base times height
equation 1/2 timed 20 times 18
- u can divide half of 20 or 18
10 times 18 = 180
Answer:
450 km (rider a)
360 km (rider b)
Step by-step explanation:
(if they are going at a constant speed you can choose any point)
find how fast rider a is going:
60/2 = 30 km/h
find how fast rider b is going:
72/3 = 24 km/h
30 km/h for 15 hours = 30 x 15 = 450 km (rider a)
24 km/h for 15 hours = 24 x 15 = 360 km (rider b)
Answer:
D. 36
Step-by-step explanation:
Ratios are a way to represent of how much there is one thing to another. It's a more simplistic representation.
For example, if there were 625 adults and 375 children, we don't say there are 625 adults to 375 children, we say there are 5 adults to 3 children.
All I did was divide both the number of children and adults by 125 and we have a ratio of 5:3 for adults to children respectively.
In this problem, we have a ratio of 3:2 for girls to boys. This 3:2 ratio is a simplistic representation of the number of girls to boys. We know that there are 24 boys.
Dividing 24/2 = 12
12 is the proportion which we multiply by the ratio to get the true numbers for boys and girls.
2 * 12 = 24 boys
3 * 12 = 36 girls
So there are 36 girls in the marching band.
