You would divide 28/3 because that's how many miles it would take. 28/3=9 1/3. Also, to help understand better, 3 miles is equal to 1 hour. So the equation would look like this: 3/1=28/?. To solve it like this, you'd divide 28/3 or 3*?=28. Whatever the answer is(9.33)you do it to the bottom. So 1*9.33. that equal 9 hours 20 min

Effectus [21]

Answer:

1/12 of the container of milk will be left in the container

Step-by-step explanation:

To solve the question, we first note the variables

Volume of milk available = 9/12 of a container

Volume of milk poured in a pan = 2/3 of a container

Quantity of milk left = Initial quantity of milk less the quantity poured out

That is 9/12-2/3 = 1/12 of the container of milk

This means that there will be only 1/12 of the container of milk left

The following table shows the estimated populations and annual growth rates for four countries in the year 2000. Find the expect

Softa [21]

Answer:

For Australia: 22,044,350

For China: 1,545,744,200

For Mexico: 145,507,500

For Zaire: 92,237,875

Step-by-step explanation:

For Australia: Population in 2000 is 19,169,000 and it is increasing steadily at a rate of 0.6% per year.

Therefore, the population in the year 2025 will be

$19169000[1+\frac{0.6 \times 25}{100} ]= 22,044,350$ (Answer)

For China: Population in 2000 is 1,261,832,000 and it is increasing steadily at a rate of 0.9% per year.

Therefore, the population in the year 2025 will be

$1261832000[1+\frac{0.9 \times 25}{100} ]= 1,545,744,200$ (Answer)

For Mexico: Population in 2000 is 100,350,000 and it is increasing steadily at a rate of 1.8% per year.

Therefore, the population in the year 2025 will be

$100350000[1+\frac{1.8 \times 25}{100} ]= 145,507,500$ (Answer)

For Zaire: Population in 2000 is 51,965,000 and it is increasing steadily at a rate of 3.1% per year.

Therefore, the population in the year 2025 will be

$51965000[1+\frac{3.1 \times 25}{100} ]= 92,237,875$ (Answer)

Which statement best describes the effect of replacing the function f(x) = 2x + 2 with the function g(x) = 2x - 3?

FrozenT [24]

The correct answer is: The graph shifts 5 units right

Explanation:
Below is the graph attached of both the equations:

Red line: Represents f(x) = 2x + 2.
Blue line: Represents g(x) = 2x - 3.

As you can see in the graph that g(x) is shifted 5 units right to f(x).

If you move towards right by 1 unit, you have to subtract 1 from f(x) until you reach g(x) like:
2x + 2 - 1 = 2x + 1 (1 unit)
2x + 1 - 1 = 2x (1 unit)
2x - 1 = 2x - 1 (1 unit)
2x - 1 -1 = 2x - 2 (1 unit)
2x -2 - 1 = 2x -3 (1 unit)

Total 5 units.

Hence the correct answer is the graph shifts 5 units right.

Solve and show your work for each question a). B). C).

Andreyy89

Answer:

Step-by-step explanation:

a) Here, the first term is .48 and the common ratio is 1/100 (since each new 48 is 1/100 th of the previous 48). a

Use the formula s = sum of geometric series = -----------

1 - r

0.48 48

which in this case is s = --------------- = ------------ = 48/99 = 16/33

1 - 1/100 100 - 1

Check this result by finding 16/33 on a calculator. Is the result equal to 0.484848484848.... ? Yes

b) Here we have the bar over the 8 only. 0.48 with the bar over the 8 is equivalent to 0.4888888888 ...

0.08

or 0.4 + 0.0888888888 ... or 0.4 + ------------

1 - 1/10

0.08 8

and this simplifies to 0.4 + ------------ = 0.4 + ---------

9/10 90

Evaluating this last result on a calculator results in 0.488888888 ...

c) 0.48 expressed as a fraction is 48/100 = 12/25

Hey Guys I need some help in answering( some areas of a Triangle) - the Question will be attached Below.

-BARSIC- [3]

Step-by-step explanation:

Rectangle has side 5 cm so one side of triangle will be 5cm

area of triangle is = 1/2lb

= 1/2 5*4

=10 cm^2

area of rectangle is l*b = 5*3= 15 cm^2

are of the shape is 10+ 15= 25 cm^2

Area of rectangle is 6*8 = 48 m^2

Area of triangle is = 1/2 *8*2= 8 m^2

area of the shape is 48+8= 56m^2
