Traveling with the current a certain boat went 16km/h. Against the same current it only went 6km/h. Find the current and the spe

Aloiza [94]

Answer:

Step-by-step explanation:

b and c are the speeds of the boat in stool water, and current, respectively.

Going with the current, the boat travels b+c=16 km/h.

Going against the current, the boat travels b-c=6 km/h

add the equations together

b+c = 16

b-c = 6

—————

2b = 22

b = 11

c = 16-b = 5

An Olympic-sized swimming pool holds 2,500,000 liters of water. How many gallons of water does an Olympic-sized swimming pool ho

tankabanditka [31]

Answer:

The Olympic sized swimming pool hold 660501.9 gallons of water.

Step-by-step explanation:

Given that:

Water hold by an Olympic sized swimming pool = 2500000 liters

We know that;

1 gallon = 3.785 liters

Therefore,

We will divide the total number of water in liters by 3.785 to find the number of gallons.

Gallons of water in pool = $\frac{2500000}{3.785}$

Gallons of water in pool = $660501.9$ gallons

Hence,

The Olympic sized swimming pool hold 660501.9 gallons of water.

Answer:

X = 6.25 ft.

Step-by-step explanation:

From the figure:

∵ Two angles in the small flag = the corresponding angles in the large flag

∴ Two flags are similar

∴ Their sides are proportional

∴ $\frac{4}{5}=\frac{5}{x} \\ x=\frac{(5)(5)}{4}=6.25$

∴ x = 6.25 ft
