Step-by-step explanation:

<AOP + < BOP = 180°< being linear pair >

x + 30° + x - 30° = 180°

2x = 180°

x = 90°

Now

<AOP = x + 30° = 90° + 30° = 120°

<BOP = x - 30° = 90° - 30° = 60°

Answer:

$1.25 per hot dog

Step-by-step explanation:

Since we have given that

A deli sells 2 hot dogs for $2.50

i.e.

Cost of 2 hot dogs = $2.50

And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.

So,

Cost of 1 hot dog is given by

2.50/2=$1.25

So, Cost of per hot dog is $1.25.

Hope this helps :)

Answer: A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.

Step-by-step explanation:

Scale factor for drawing = 2:1

Dimensions of drawing :  10 in, 5 in, 13 in

Dimension of object = Scale factor x Dimension of drawing

Sides of object:

2 x 10 in =20 in   [b]

2 x 5 in = 10 in  [c]

2 x 13 in = 26 in.  [a]

Hence, the correct option is

A. Side a is 26 inches long, side b is 20 inches long, and side c is 10.

Answer:

Side a is 2.5 inches long, side b is 5 inches long and side c is 6.5 inches long.

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:

The slope-intercept form of the equation of the line is:

y = 2/3x + 2

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

Given the points

(x₁, y₁) = (0, 2)

(x₂, y₂) = (3, 4)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [4 - 2] / [3 - 0]

               = 2 / 3

Thus, the slope of the line = m = 2/3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept b = 2

now substituting m = 2/3 and b = 2 in the slope-intercept form

y = mx+b

y = 2/3x + 2

Therefore, the slope-intercept form of the equation of the line is:

y = 2/3x + 2

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:

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

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.
