Answer:

Cost of table is $237

Step-by-step explanation:

Cost of chair, table and lamp = $562

Cost of lamp = x

Cost of chair = 4x  (The chair costs 4 times as much as the lamp)

Cost of table = 4x-23 (the table costs $23 less than the chair.)

We need to find the cost of table.

We know that:

Cost of chair, table and lamp = $562

We can write:

[tex]x+4x+4x-23=562[/tex]

First, we need to find value of x by solving the equation.

[tex]x+4x+4x-23=562\\9x=562+23\\9x=585\\x=\frac{585}{9}\\x=65[/tex]

So, we get x = 65

Now, we can find cost of table:

We are given:

Cost of table = 4x-23

Cost of table = 4(65)- 23 = 237

So, Cost of table is $237

Answer:

1 round = 220 meter wire

2 rounds = 440 meter wire

3 rounds = 660 meter wire

Step-by-step explanation:

Given that:

Perimeter of squared garden = 220m

As the perimeter is given, the length of the wire would be calculated with it.

The length of wire to fence with 1 round = 220 * 1 = 220m

The length of wire to fence with 2 rounds = 220 * 2 = 440m

The length of wire to fence with 3 rounds = 220 * 3 = 660m

Hence,

1 round = 220 meter wire

2 rounds = 440 meter wire

3 rounds = 660 meter wire

Step by step problem

Answer:

20=-1

60=-3

100=-5

240=-12

Step-by-step explanation:

divide time and depth by 20

When time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time.

From the table let us take the values of time and depth which both are given.

Time=100 and depth is -5.

From this we can find the other values.

Depth=-1 when time is x

100/-5=x/-1

100=5x

Divide both sides by 5

x=20

So when time is 20 the depth is -1.

Now we have to find the depth when time is 60.

60/x=100/-5

-300=100x

x=-3

So when time is 60 the depth is -3.

Now we have to find the depth when time is 240.

240/x=100/-5

-1200=100x

Divide both sides by 100

x=-12

when time is 240 the depth is -12.

Hence, when time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.

Answer:

Step-by-step explanation:

The data of timing for each lap will form a arthmetic progression ( AP ) with first term as 25 s  and common difference of 1.6 s .

a )

first term a = 25

common difference d = 1.6 .

10 th term of the series can be given by following formula

a₁₀ = 25 + ( 10-1 ) x 1.6

= 25 + 1.6 x 9

= 39.4 s

b )

Let n th be the last lap

a(n) = a + ( n-1 ) x d

55.4 = 25 + ( n- 1 ) x 1.6

n - 1 = 19

n = 20 .

c )

sum of all the term of AP

=(  first term + last term ) x no of term / 2

= (25 + 55.4 ) x 20 / 2

= 804 s .

= 804 / 60 min

= 13.4 min .

Answer:

The step by step explanation isn't your problem but it is a way to see how to do your problem

Step-by-step explanation:

This is an exponential growth equation, therefore, it follow the standard form:

where y is the value of the house after a certain number of years,

a is the initial value of the house,

b is the growth rate, and

x is the year number.

We are going to make this easy on ourselves and call year 1985 year 0. Therefore, is year 1985 is year 0, then year 2005 is year 20, and year 2010 is year 25. We will make these the x coordinates in our coordinate pairs.

(0, 113000) and (20, 155000)

Filling into our standard form using the first coordinate pair will give us the initial value of the house at the start of our problem:

Anything raised to the 0 power is equal to 1, so

113000 = a(1) and

a = 113000

Now we will use that value of a along with the second pair of coordinates and solve for b, the growth rate you're looking for:

Start by dividing both sides by 113000 to get a decimal:

To solve for b, we have to undo that power of 20 by taking the 20th root of b. Because this is an equation, we have to take the 20th root of both sides:

The 20th root and the power of 20 undo each other so all we have left on the right is a b, and taking the 20th root on your calculator of the decimal on the left gives you:

b = 1.0159 which rounds to

b = 1.02 This is our growth rate.

Now we can use this growth rate and the value of a we found to write the model for our situation:

If we want to find the value of the house in the year 2010 (year 25 to us), we sub in a 25 for x and do the math:

Raise 1.02 to the 25th power and get:

y = 113000(1.640605994) and multiply to get a final value of

y = $185,388

Answer:

-15/9

Step-by-step explanation:

The slope is the steepness of the line. To find it, you divide how far up it goes by how far across it goes. This equals the diagonal incline. To find it with points, you find the difference between the y values and divide that by the difference in the x values!

-9-6=-15

10-1=9

-15/9=-15/9

This slope means that for every nine units the line goes across, it goes down 15 units!

Have a wonderful day :D
