A turtle swims at a speed of 1584 meters per hour. A girl swims at a speed of 1380 millimeters per second. 10 mm = 1 cm 1 m = 10
adelina 88 [10]
The girl's speed is 1380mm/sec * 1cm/10mm * 60sec/minute (since 1cm=10mm and 60 sec=1 minute)= 1380*60cm/10min= 1380*6cm/min
=8280 cm/min. For the turtle, we have 1584 m/hr * 1 hr / 60 min * 100 cm /1m (we have to make sure that they cross out, so e.g. for the hour we multiply it by 1 hr/60 min since the original hour is on the bottom)= 158,400cm/60min
=15840cm/6min
= 2640 cm/min
Since the girl is 8280 cm/min and the turtle is 2640 cm/min, we divide them to get 8280/2640= around 3.136 cm/min

Which hill is steeper?
Stella [2.4K]

Answer:

B. A hill that rises 2 feet for every 15 feet of run.

Step-by-step explanation:

The two must have COPs. We'll narrow them down.

For A, we divide 10 by 2.

\frac{10}{2} = 5.

For B, we divide 15 by 2.

\frac{15}{2} = 7.5.

B has the larger number, so it is B.

Solve for u.<br> 36 – 9u = 27
strojnjashka [21]

Answer:

u = 1

Step-by-step explanation:

First, we can use inverse operations to help.

27 + 9u = 36

Next, we can start replacing u with numbers to find which number fits in u.

27 + 9(1) = 36

27 + 9(2) ≠ 36

27 + 9(3) ≠ 36

Now, we know that u = 1
