If George's driveway is a rectangle 12.2 m by 3.0 m, its dimensions in cm are

... 1220 cm long × 300 cm wide × 2 cm deep

Thus the volume of gravel required is

... (1220 × 300 × 2) cm³ = 732,000 cm³

George needs about 0.732 bags, so he will probably need to buy 1 bag.

A certain ferry moves up and down a river between Town A and B. It takes the ferry two hours to travel to Town A and only an hou

Y_Kistochka [10]

Answer:

The distance between two cities is 60 miles.

Step-by-step explanation:

Time taken to travel from B to A = 2 hours

Time taken to travel from A to B = 1.5 hours

Current speed = 5 mph

Let the speed of ferry in still water = u mph

When the ferry moves with the current, it will taken lesser time (i.e. A to B) and when it moves against the current it will take more time (i.e. B to A).

Let the distance between the two cities A and B = D miles

While moving with the current, speed = $(u+5)\ mph$

While moving against the current, speed = $(u-5)\ mph$

Formula for Distance = Speed $\times$ Time

Distance traveled in each case is same i.e. D.

So,

$D = (u+5) \times 1.5 = (u-5) \times 2\\\Rightarrow 1.5u+7.5=2u-10\\\Rightarrow 0.5u =17.5\\\Rightarrow u = \dfrac{175}{5}\\\Rightarrow u = 35 \ mph$

Now,

$D = (u+5) \times 1.5\\\Rightarrow D =(35+5) \times 1.5\\\Rightarrow D =(40) \times 1.5\\\Rightarrow \bold{D =60\ miles}$

So, the distance between two cities is 60 miles.

MULTIPLE CHOICE A thermometer is

pav-90 [236]

The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F

Thermometer accuracy = ±2°F
Thermometer reading = 17°F

The least possible value of temperature can be calculated thus :

Thermometer reading - thermometer accuracy

17 - 2 = 15°F

The highest possible temperature can be calculated thus :

Themometer reading - thermometer accuracy

17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
