Answer:

Trees contribute to their environment by providing oxygen, improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce the oxygen we breathe.

Trees give off oxygen that we need to breathe. Trees reduce the amount of stormwater runoff, which reduces erosion and pollution in our waterways and may reduce the effects of flooding. Many species of wildlife depend on trees for their habitat. Trees provide food, protection, and homes for many birds and mammals.

They give us clean water to drink, air to breathe, shade, and food to humans, animals, and plants. They provide habitats for numerous species of fauna and flora, firewood for cooking and heat, materials for buildings and places of spiritual, cultural, and recreational importance.

Answer:

Hello! The answer is 280 meters :)

Step-by-step explanation:

The radius is basically just the diameter halved - in other words, the diameter is the radius multiplied by 2.

So if we multiply the radius (given, 140) by 2, we get 140 x 2, which is 280!

The diameter of the track is 280 meters.

Step-by-step explanation:

Answer:

-38,588 (losing chances)

7,016 (winning chances)

Step-by-step explanation:

There are 52 cards in a standard deck.

4 suits: hearts, diamonds, clubs, and spades

Each suit has four 2's, and four 3's. That means that there are 8 chances you will win $41. and 44 chances you will lose $11.

8 × 877 = 7,016 chances you will win $41.

44 × 877 = 38,588 chances you will lose $11.

Using an exponential function, it is found that the projected growth rate is of 4.5%.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + k)^t[/tex]

In which:

In this problem:

We use the information given to solve for k.

[tex]A(t) = A(0)(1 + k)^t[/tex]

[tex]37.1 = 23.9(1 + k)^{10}[/tex]

[tex](1 + k)^{10} = \frac{37.1}{23.9}[/tex]

[tex]\sqrt[10]{(1 + k)^{10}} = \sqrt[10]{\frac{37.1}{23.9}}[/tex]

[tex]1 + k = \left(\frac{37.1}{23.9}\right)^{\frac{1}{10}}[/tex]

[tex]1 + k = 1.045[/tex]

[tex]k = 0.045[/tex]

The growth rate was of 4.5%.

Answer:

10 inches

Step-by-step explanation:

we know that 2 inches is equal to 50 miles, so:

2x = 50

x= 25, which means that 1 inch is 25 miles.

250/25 = 10, which means that it would take 10 inches to be equal to 250 miles.

=============================================================

Explanation:

It helps to make a table of all possible outcomes. Refer to the diagram below. Along the top we have the outcomes 1,2,3,4. Along the left side we have 2,3,4,5. Each row & column header is then added to form the corresponding inner cell. For example, in the top left corner we have 1+2 = 3.

There are 4 outcomes of spinner A and 4 outcomes of spinner B. This means we have 4*4 = 16 outcomes overall. Out of those 16 sums, we have the odd results {3,5,7,9} show up 1+3+3+1 = 8 times.

The probability we want is therefore 8/16 = 1/2. This is expected since half of the values of {1,2,3,4} are odd, and the same applies to {2,3,4,5}. So we should expect half of the sums to be odd as well.

Put another way: for any row or column, you'll find that the pattern is odd/even/odd/even or even/odd/even/odd. This shows that 50% of any row or column represents an odd number. This idea extends out to the entire table overall.

Answer:

1/2.

Step-by-step explanation:

There are 2 odd and 2 even numbers on each spinner.

Odd totals will come from an odd number from the first spinner and an even number from the second spinner, or vice versa.

So the number of possibilities  of an odd total = 2 * (2 * 2) = 8.

The total number of all possible outcomes = 4*4 = 16.

So the required probability is 8/16 = 1/2.

Step-by-step explanation:

Answer:As most maths problems, you don’t have to convert it immediately in numbers to solve it.

It’s obvious that John works twice as fast as Tom to paint the same surface. It means that if they work simultaneously, at any time John will always have painted twice as much surface as Tom. So if they plan it properly and they end the painting of the room at the same time, John will have painted twice as much surface as Tom.

There is only one possibility : if Tom painted 1/3 of the room and John painted 2/3.

Now, if Tom painted 1/3 of the room it probably took him 1/3 of the time needed to paint the entire room, or 12/3=4 hours. It also works for John : 6*2/3=4 hours

Answer:

x=12

Step-by-step explanation:

overline AD = overline AB + overline BD

overline AD =10+10

overline AD =20

tan( angle BAC)= overline BC/overline AB

tan( angle BAC)= 6/10

angle BAC=30.964°

angle DAE= angle BAC

angle DAE=30.964°

tan( angle DAE)= overline DE/AD

tan (30.964 degrees) = x/20

x = 12
