It would take 0.58 hours to cover a distance of 1 kilometer.

The speed of a body is defined as the total distance covered by the body per unit time by taken by the body.

S = D/t

where,

S is the speed of the body,

D is the distance covered by the body and

t is the time taken by the body.

Here, in the provided situation,

The distance D to be covered is 1 kilometer.

The speed S at which the body moving is 1.7 km/h.

using formula,

S = D/t

1.7 = 1/t

t = 1/1.7

t = 0.58 hours.

Time taken by the body is 0.58 hours.

The number of miles that both the green car and the blue car have to drive to cost the same amount is equal to 28.5 miles.

The number of miles both cars have to travel to cost the same amount can be determined using an algebraic expression. An algebraic expression can be defined as a mathematical equation consisting of both letters and numbers.

As the green car (gc) cost $15 plus $0.50 per mile and the blue car (bc) costs $25 plus $0.15 per mile, an algebraic expression for this problem can be given as follows;

15 + 0.50(x) = 25 + 0.15(x)

Solving for x;

0.50x - 0.15x = 25 - 15

0.35x = 10

x = 10 / 0.35

x = 28.5

Hence, both cars have to drive 28.5 miles to cost the same amount.

An exponential model to represent this situation  [tex]P =17000 (0.96)^{t}[/tex]

Exponential growth occurs when a population's per capita growth rate remains constant regardless of population size, causing the population to grow faster and faster as it grows larger.

In exponential growth, the per capita (per individual) growth rate of a population remains constant regardless of population size, causing the population to grow faster and faster as it grows larger. In nature, populations may grow exponentially for a time, but they are eventually constrained by resource availability.

Given that,

P represents population, and

t the number of years of growth.

As we know,

P = [tex]a(b)^{t}[/tex]  

[here 'a' is the initial amount of population and 'b' is the amount of growth or shrink]

To get 'b,' start at 1 and either add or remove the decimal growth rate depending on whether it is rising or decreasing.

In this case a = 17,000, it is the value of population at the time zero.

As the population decreases 4% each year, then b = 1-0.04 = 0.96

So, the equation becomes, P = [tex]17000 (0.96)^{t}[/tex]

The cost of the entrance ticket for a child is $12.80.

Using algebraic expression and equation, we can express each statement and determine the cost of the entrance ticket for a child

Let x = cost of the entrance ticket for a child

y = cost of the entrance ticket for an adult

If the cost of the entrance tickets to the zoo for 2 adults and 3 children is $78.80, then we can express this as:

3x + 2y = $78.80     (equation 1)

If the cost of the entrance tickets for 1 adult and 1 child is $33.10, then we can express this as:

x + y = $33.10     ⇒     x = $33.10 - y     (equation 2)

Substitute equation 2 to equation 1 and solve for y.

3x + 2y = $78.80     (equation 1)

3($33.10 - y) + 2y = $78.80

$99.30 - 3y + 2y = $78.80

3y - 2y = $99.10 - $78.80

y = $20.30

Substitute the value of y to equation 2 and solve for x.

x = $33.10 - y     (equation 2)

x = $33.10 - $20.30

x = $12.80

cost of the entrance ticket for a child = $12.80

a) Domain of the function 0 ≤ d ≤ 21 (0,21)

Range of the function 0 ≤ B ≤ 400 (0,400)

b) Estimate to the nearest hundreds for B(0) is 200

c) Ebony's bank balance first reached $0 on day 12 can be shown as functional notation as - we can add the number 12 below the first point reaching the horizontal axis.

d) Ebony's bank balance remained $0 from day 12 through day 15. The segment which represents the information is - segment 4.

(a) Domain: the collection of values used as input or arguments for the function.

Range: Either the codomain or the function's image is mentioned.

For three weeks, Ebony's bank account was active (21 days). then the domain is 0 ≤ d ≤ 21 (here 'd' refers to day)

Her highest balance was $400 and her lowest was zero, so the range is  0 ≤ B ≤ 400. (Here, 'B' refers to Balance)

(b) When d = 0, the graph's highest point, which represents her highest balance of $400, is displayed. This means that on the first day, the point will probably only be half as high as the highest point. Therefore, we may calculate the nearest hundred for B(0) is about equal to 0.5 * 400 = 200.

(c) In other words, the line of the function first touches the horizontal axis at d = 12; the balance first reached $0 on day 12. Below the first point that reaches the horizontal axis, we can add the number 12.

(d) From day 12 through day 15, the bank balance stayed at zero dollars; this is shown by the vertical axis of segment 4 of graph 4.

Step-by-step explanation:

The average temperature on Earth is greater than the average temperature on Jupiter by 225°F.

The average temperature on earth is greater than the average temperature in Jupiter by 225°F. This can be obtained by getting the average temperatures as follows:

The average temperature on Earth is = 59°F

The average temperature on Jupiter is = -166°F.

Now we represent this in an equation as follows:

-166°F + x = 59°F

x = 59 - (-166)

x = 59 + 166

x = 225°F.

Step-by-step explanation:

1.25÷18=0.0694

0.78÷12=0.065

The packet of 12 biscuit have better value.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The cost of Packet of 12 biscuit = £0.78

The cost of Packet of 18 biscuit = £1.25

Now,

Since, The cost of Packet of 12 biscuit = £0.78

Hence, The cost of Packet of 1 biscuit = £0.78/12

                                                           = £0.065

And, The cost of Packet of 18 biscuit = £1.25

Hence, The cost of Packet of 1 biscuit = £1.25/18

                                                           = £0.0694

Thus, The packet of 12 biscuit have better value.

Maximum: 175

Step-by-step explanation:

To do this, you know that Jake had a goal of getting $150 in the week. He was within $25 of reaching his goals. This means that he could have $25 less than or more than $150.

You can subtract 25 from 150 to get his minimum:

$150 - $25 = $125

And you can add 25 to get his maximum:

The key is to realize that a 30 60 90 triangle can be constructed and the height of the house can be found from there. It may be helpful to draw a diagram.
I will use the diagram attached for reference to this solution.

Remember that the answer is asking for y, or the length of DE.

The angle CAB is 30 degrees, and the angle ACB is 90 degrees
The length of CB is 25 * sqrt3
Since ACB is a 30 60 90 triangle, and we know the length of one of the sides, the length of the other sides can be calculated.
CB is the shortest length, and so the middle length, AC, is sqrt(3) times longer than the length of the shortest length, CB

CB's length * sqrt 3 = AC's length = 25 * sqrt3 * sqrt3

AC = 75

length of A to F (I can't combine the letters a and f because then brainly thinks i'm swearing ) = 75 + x = 107

x = 32

Since length of BE = length of CF,

32 = BD + DE = 1.8 + y

Stavros has 9 at least quarters and 13 at most coins.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given Data

Stavros has 22 coins in his piggy bank, all dimes and quarters. Altogether, the coins are worth more than $3.40.

He only has quarters and dimes in his possession. For quarters and dimes, assign variables.

Let x = the quantity of dime

Let y = the quantity of quarters.

Create an inequality and equation to depict the scenario.

We can use an equation because he has exactly 22 coins.

x + y = 22

He has more than $3.40 in his total, thus we can apply an inequality.

0.10x + 0.25y > 3.40

To figure out how many of each coin he possesses, we apply the substitution approach. In order to express the inequality in terms of x, substitute the equation into the inequality.

0.10x + 0.25(22 - x) > 3.40

The inequality can now be resolved.

0.10x + 5.5 - 0.25x > 3.40

-0.15x + 5.5 > 3.40

-0.15x > -2.1

x > 14

In an equation where we divide by a negative coefficient, We reverse the sign in inequality.

x < 14

Stavros has a maximum of 13 dimes.

The value of x can then be substituted into the equation since an equation provides you the most precise and minimal value you can have.

y = 22 - 13

y = 9

Stavros has 9 quarters and 13 dimes.

Bacteria grow at a rate of 10% per hour in a petri dish.

This gives us an idea that in another 1 hours we will have 100000 cells organisms.
