A small heater has a rectangular filter that has a width of 16.0 in. and a length of 20.0 in. Another larger heater requires a similar filter that has a 56 in. width. What is the length (in inches) of this larger filter? (Round your answer using the rules for working with measurements.)

The solution of the system of equations are x = -4 and y=1.

How to solve system of equations?

5x+y=-19  -- (i)

5x-4y=-24 ---(ii)

Subtract the above two equations:

5y = 5

y = 1

Substitute y=1 in equation (ii)

5x - 4(1) = -24

5x = -20

x = -4

Hence, the solution of the system of equations are x = -4 and y=1.

Answer:

Is there an image? I cant figure it out without the image

Step-by-step explanation:

Answer:

y = 4

Step-by-step explanation:

Both the triangles are congruent by SSS postulate.

Therefore,

[tex]4y + 8 = 24 \\ (corresponding \: sides \: of \: \\ congruent \: \triangle s) \\ 4y = 24 - 8 \\ \\ 4y = 16 \\ \\ y = \frac{16}{4} \\ \\ y = 4[/tex]

What you're looking at in this image are two alternate exterior angles.

Alternate exterior angles, are, essentially, exterior angles of a transversal that runs through two parallel lines. These angles are on alternating sides. These angles, assuming the lines are parallel, must be equal.

There's a proof behind why these angles are equal, but I won't bore you with the specifics as the question doesn't require it.

So - we know that these two angles must be equal to prove that the lines A and B are parallel. Knowing this, we can write an equation:

5x + 20 = 3x + 60

Subtract 20 from both sides:

5x + 20 - 20 = 3x + 60 - 20

5x = 3x + 40

Subtract 3x from both sides:

5x - 3x = 3x - 3x + 40

2x = 40

x = 20

Answer:

  A.  x = {nπ, π/4 +nπ}

Step-by-step explanation:

The zero product rule tells you the solutions are found where the factors are zero:

  tan(x) = 0   ⇒   x = nπ

  tan(x) -1 = 0   ⇒   x = arctan(1) +nπ = π/4 +nπ

Answer:

Okay so for this one use the Pythagorean theorem

Step-by-step explanation:

A^2 + 28^2 = 128^2

You are trying to find A.

So 28^2 is 784

128^2 is 16384

Now you will subtract 784 from both sides of the equation your new equation should be this: a^2 = 15600

Now you find the square root of both sides which gives you: A= 124.89 round it to 125

The measures in this problem are given as follows:

1. x = 14.

2. m < 1 = 58º.

3. m < 2 = 122º.

Angles 1 and 2 are supplementary, as the angle 1 and the consecutive interior angle with angle 2 are corresponding angles, meaning that they are congruent, and then the angles are supplementary with their consecutive interior angles.

When two angles are supplementary, the sum of their measures is of 180º, hence the measure of x is obtained as follows:

m < 1 + m < 2 = 180

2x + 30 + 8x + 10 = 180

10x + 40 = 180

10x = 140

x = 140/10

x = 14.

Then the angle measures are obtained as follows:

advantages and disadvantages to using either a debit card or a credit card.

Answer:

Advantages & disadvantages given below

Step-by-step explanation:

Advantages;

1. They have low fees; for example almost all store credit cards don't charge annual fees but instead they promote some very good offers.

2. Possibility of having discounts from retailers; because majority of retailers usually love promoting their credit cards because it helps them ensure they save more money and they hold on to this principle judiciously. For example there could be discounts upon first purchase or when you shop at target stores which they offer.

3) Majority of store credit cards offer a lot of benefits for members. For, owners of store credit cards could be offered the option of returning purchased items without presenting the receipt. There could also be I stances where they are giving free shipping of their products or they could be exposed to some good favorable payment plans.

Disadvantages;

1. Their credit limits are usually far lower than those of credit and debit cards.

2. Other cards give more flexible discount and reward system to its customers. This includes cash back or giving the incentive of earning more points when they spend beyond a certain amount.

Answer:

  x = {-2, 0, 2}

Step-by-step explanation:

You want the solutions to √((√(x²) -1)²) = 1.

Squaring both sides gives ...

  (√(x²) -1)² = 1² = 1

Taking the square root of both sides gives ...

  √(x²) -1 = ±1

Adding 1, we have ...

  √(x²) = 1 ± 1 = {0, 2}

We know that √(x²) = |x|, so this reduces to ...

  |x| = {0, 2}

  x = {±0, ±2}

  x = {-2, 0, 2}

V =1884 in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is the radius and h is the height

V = pi ( 10) ^2 * 6

V = pi ( 600) in^3

Using 3.14  for pi

V = 3.14 * 600 in ^3

V =1884 in ^3

From the information provided, we know that the surveying method for the polling depends on the no. of calls got on the two sorts of 900 phone numbers.  

This surveying strategy doesn't address a random sample in light of the fact that the viewers who see the show can be restricted. Additionally, among the viewers of the show, the reactions depend on viewers who intentionally approach to offer or air their opinion. Therefore, the acquired sample doesn't address a random sample and specifically, we can posit that the sample occurs to be a voluntary sample.

Answer:

(0,4)

Step-by-step explanation:

The given equations are :

3y = 6x + 12  

2x - y = -4

If (-3,2) be the solution of the above equations,

3(2) = 6(-3) + 12

6 = -18+12

6≠ -6  

2x - y = -4

2(2) -(-3) =-4

4+7 = -4

11 ≠ -4

No, (-3,2) is not the solution.

Similarly, put (0,4) in the abve equations,

3(4) = 6(0) + 12

12 = 12

and

2(0) - 4 = -4

-4 = -4

Hence, (0,4) is a solution of the given equations.

Answer:

Graph #1 - y=-20x+40

Graph #2 - y=5x+10

Step-by-step explanation: The first thing that you do is pull two points from each of the graphs and find the slope. To find the slope you use

FROM GRAPH #1:

(x1,y1)    (x2,y2)

   80-40/2-3

      20/-1

    M = -20

FROM GRAPH #2:

(x1,y1)  (x2,y2)

  20-10/3-1

     10/2

    M = 5

2. Now once you find the slope you will use the equation of a line formula to form an equation.

The (mx) is your slope, the (b) is the y-intercept. (any value on the y-axis)

3. Since we now know the equation of a line and the slope we will substitute the variables.

Graph #1:

y=mx+b

y=-20x+40

Graph #2:

y=mx+b

y=5x+10
