Answer:

(a) The width is 40 inches

(b) It will not

Step-by-step explanation:

Given

D = 50 -- Diagonal

Solving (a): H = 30 --- (height).

Find the width (W)

To do this, we make use of Pythagoras theorem

D^2 = H^2 + W^2

This gives:

50^2 = 30^2 + W^2

2500 = 900 + W^2

Collect Like Terms

W^2 = 2500 - 900

W^2 = 1600

Take square roots

W = 40

Solving (b): Will it fit into a 30 in wide cabinet?

In (a) above, we calculated the width of the TV to be 40 inches

This implies that, the width is greater than the width of the cabinet.

<em>So, it will not fit in</em>

9+3|5-x|=24<br><br> What is the lines for and how do I solve X with them?
Ivahew [28]

Answer:

the lines represent absolute value bars

x=0,10

Step-by-step explanation:

STEP 1: Move all terms not containing |5−x| to the right side of the equation.

3|5-x|=15

STEP 2: Divide each term by 3 and simplify.

|5-x|=5

STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.

<em>5-x=±5</em>

STEP 4: Set up the positive portion of the ± solution.

5-x=5

STEP 5: Solve the first equation for x.

x=0

STEP 6: Set up the negative portion of the ± solution.

5-x=-5

STEP 7: Solve the second equation for x.

x=10

NOTE: The solution to the equation includes both the positive and negative portions of the solution.

x=0,10

a tennis supply store pays a wholesaler $90 for a tennis racquet and sells it for $144 what is the markup rate
dexar [7]
Markup is the difference between the cost of a good or service and its selling price. A markup is added onto the total cost incurred by the producer of a good or service in order to create a profit. The total cost reflects the total amount of both fixed and variable expenses to produce and distribute a product.so it would be 144 - 90 = 54. $54 would be the markup.
