Answer:
7:8
Step-by-step explanation:
First, you need to find out how many men there are. 150-80=70 men. The ratio would be 70:80. Then you need to simplify it. the simplified answer is 7:8
How do you imagine that you will use measurement in your future career?
Answer:
55mph
None of the option is correct
Step-by-step explanation:
Let v be the speed and t as the time taken. If speed varies inversely as the time it takes to drive, then v ∝ 1/t.
v = k/t where k is the constant of proportionality.
IF it takes Kris 5 hours when driving at 55 mph, then v = 55mph when t = 5 hours.
Substituting this values into the formula above;
55 = k/5
k = 55*5
k = 275mp/hr²
To calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t
v = 275/5
v = 55 mph
<em>Hence, martin will also need to drive at 55mph to take 5 hours</em>
4x+15y=G insert total hours- 30.5 for x and 1 for y and G will be your answer to problem B
