hi please help im so confused, i'm doing an escape room, i have no clue what this means. here is the question also: "Solve for the values of E, F, G, and H, and then input the secret number to unlock this door!"

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!

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:

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

a constraint is a condition of an optimization problem that the solution must satisfy.

Objective function:  z

x =  number of contemporary style

y = number of farmhouse style

We have to find the cost

The carpentry costs is,

15*2*x  +  15*2,5*y    = 30*x  +  37,5*y

The painting costs is

12*1,5*x  +  12*1*y      =  18*x  +  12*y

Answer:

2 gallons

Step-by-step explanation:

If Han used 1 1/2 gallons of paint to paint 3/5 of a shed, this can be expressed as;

1 1/2 gallons = 3/5 of the shed

3/2gallons = 3/5 of the shed

To find the number of gallons that will paint the whole shed, we will say;

x gallons = 1 shed

Divide both expressions

3/2/x = 3/5

3/2x = 3/4

2x * 3 = 3*4

6x = 12

x = 12/6

x = 2

Hence 2 gallons will be needed for the whole shed

Answer:

ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C

Step-by-step explanation:

dy/dx + 2y = 6

This is a first order linear ODE.

p(x) = 2

Integrating factor: I(x) = e^(∫ 2 dx) = e^(2x)

e^(2x)(dy/dx + 2y) = 6e^(2x)

e^(2x) dy + 2ye^(2x) dx = 6e^(2x) dx

Integrate both sides of the equation.

ye^(2x) = 3e^(2x) + C

Thus, the general solution is ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C.

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
