We conclude that:

[tex]20\times \:3\frac{1}{5}=64[/tex]

Step-by-step explanation:

Given the expression

[tex]20\:\times 3\frac{1}{5}[/tex]

convert mixed number to improper fraction: [tex]a\frac{b}{c}=\frac{a\times c+b}{c}[/tex]

i.e. [tex]3\frac{1}{5}=\frac{3\times 5+1}{5}=\frac{16}{5}[/tex]

so the expression becomes

[tex]20\:\times 3\frac{1}{5}\:=20\times \:\frac{16}{5}[/tex]

Factor the number: 20 = 5×4

[tex]=5\times \:4\times \frac{16}{5}[/tex]

Cross-cancel common factor: 5

[tex]=4\times \:16[/tex]

Multiply the numbers: 4×16 = 64

[tex]=64[/tex]

Therefore, we conclude that:

[tex]20\times \:3\frac{1}{5}=64[/tex]

An animal reserve has 20,000 elk. The population is increasing at a rate of 8% per year. This can be modeled by the function P(t) = 20,000 (1.08)^t where t represents time in years and P(t) represents the elk population. What is the estimated population of elk in 6 years?

Answers

Answer:

The answer would be 31,737 elks.

Step-by-step explanation:

You would solve this by multiplying 1.08 by the power of 6 which equals 1.586874322944. You would then multiply this number by 20,000 which equals 31,737.4865 but since you can’t have .4865 of an elk the answer is just 31,737.

Consider the statement: 4−3+5=−6+8+4. This is a mathematically correct sentence.Is the sentence true or false? Explain how you know.

Answers

Answer:

This is true because 6 does infact equal 6

Step-by-step explanation:

First see if the solution is true by seeing if x = x

So solve both sides

4-3+5 = -6+8+4

1+5 = 2+4

Two of your friends go bowling. One friend rents a pair of bowling shoes for $3 and bowls 3 games. The other friend brings his own bowling shoes, bowls 4 games and buys a soda for $0.50. Both friends spend the same amount of money. Show how you can write and solve an equation to find the cost of one game.

Answers

Answer: The cost of each game is $2.50

Step-by-step explanation:

Let's find the equations for each friend:

Friend 1:

Pays $3 for the shoes, and plays 3 games, then if X is the cost of each game, Friend 1 pays a total of:

$3 + 3*X

Friend 2:

This friend buys a soda for $0.50, and he plays 4 games, remember that the cost of each game was X. then this friend pays:

$0.50 + 4*X

And we know that both friends pay the exact same amount, then we can write:

$3 + 3*X = $0.50 + 4*X

And solve this for X.

We need to isolate X, then we can move all the terms with X to the right, and all the terms without X to the left:

$3 - $0.50 = 4*X - 3*X

$2.50 = (4 - 3)*X = X

This means the cost of each game is $2.50

2) Dylan walked 1/3 miles in 20 minutes How far will he goes in miles distance in 120 minutes?

Answers

Answer:

Question 1 : If you mean how many miles will he run in 1 hour then it is 1 Mile | Question 2 : 2 Miles

Step-by-step explanation:

Question 1 :

1/4 x 4 (because of the hour being split into fourths) = 1 Mile

Question 2 :

120 / 20 = 6, 6 x 1/3 = 6/3, simplified = 2

When a coin was tossed, it came up heads 12 times and tails 8 times.
What percent of the time did it come up tails?

Answers

Answer: 40% of the time the coin came up tails.

Step-by-step explanation:

The coin is tossed 20 times. Of those 20 times, it came up tails 8 times (8/20). 8/20 = 0.4 = 40%

Answer:

It’s 1/2 (the probability of getting either heads or tails) to the power of 8 (for 8 tosses).

1/2*1/2*1/2*1/2*1/2*1/2*1/2*1/2=1/128=0.00390625 =40%

A park has the dimensions indicated in the diagram. Which expression represent the perimeter of the park?

Answers

Answer:

78m.

Step-by-step explanation:

Since we are not given any dimension we can use the following dimension.

Let the park be rectangular in nature

Length = 25m

Width = 14m

Perimeter = 2(L+W)

Perimeter = 2(25 + 14)

Perimeter = 2(39)

Perimeter = 78m

Hence the perimeter of the park is 78m.

Note that the dimension were assumed and any values can be used using similar calculation.
