What is the area of the rectangle in square units and how can i explain my answer
ZanzabumX [31]
The area of your rectangle will vary depending on the dimensions.  The area of any rectangle can be found with a simple equation...

Area = Length x Width    or    A = l x w

The answer to the area question will ALWAYS be in square units because when you multiply, you also multiply the units so, for example 2 inches x 2 inches = 4 inches^2.

Let's take a look at an example...  You have a rectangle with a length of 8 feet and a width of 4 feet.  What's the area?

Well... Area = Length x Width,  so

Area = 8 ft x 4 ft
Area = 32 ft^2

Easy as that!

In triangle △JKL, ∠JKL is right angle, and KM is an altitude. JK=24 and JM=18, find JL.
PolarNik [594]

Answer:

JL ≈ 32  

Step-by-step explanation:

The triangle JKL  has a side of JK = 24 and we are asked to find side JL. The triangle JKL is a right angle triangle.

Let us find side the angle J first from the  triangle JKM. Angle JMN is 90°(angle on a straight line).

using the cosine ratio

cos J = adjacent/hypotenuse

cos J = 18/24

cos J = 0.75

J = cos⁻¹ 0.75

J = 41.4096221093

J ≈ 41.41°

Let us find the third angle L of the triangle JKL .Sum of angle in a triangle = 180°. Therefore,  180 - 41.41 - 90 = 48.59

Angle L = 48.59 °.

Using sine ratio

sin 48.59 ° = opposite/hypotenuse

sin 48.59 ° = 24/JL

cross multiply

JL sin 48.59 ° = 24

divide both sides by sin 48.59 °

JL = 24/sin 48.59 °

JL = 24/0.74999563751

JL = 32.0001861339

JL ≈ 32

Y varies directly with x it has a constant rate of change of 6. When the value of y is 11, then the value of x could be?
makvit [3.9K]

Answer: \frac{11}{6}

<u>Explanation:</u>

y varies directly with x means: \frac{y}{x} = k  ; where k is the rate

  • \frac{y}{x} = k
  • \frac{11}{x} = 6
  • (x)\frac{11}{x} = 6(x)
  • 11 = 6x
  • \frac{11}{6} =\frac{6x}{6}
  • \frac{11}{6} = x

44. Melissa helps her grandfather at his store. Each mornin
Goryan [66]

<h2>HOW TO: SOLVE AN APPLICATION</h2>

Step 1. Identify what you are asked to find and choose a variable to represent it.

Step 2. Write a sentence that gives the information to find it.

Step 3. Translate the sentence into an equation.

Step 4. Solve the equation using good algebra techniques.

Step 5. Check the answer in the problem and make sure it makes sense.

Step 6. Write a complete sentence that answers the question.

Remember that whatever the application, once we write the sentence with the given information (Step 2), we can translate it to a percent equation and then solve it.

Do you pay a tax when you shop in your city or state? In many parts of the United States, sales tax is added to the purchase price of an item. See Figure 6.7. The sales tax is determined by computing a percent of the purchase price.

To find the sales tax multiply the purchase price by the sales tax rate. Remember to convert the sales tax rate from a percent to a decimal number. Once the sales tax is calculated, it is added to the purchase price. The result is the total cost—this is what the customer pays.
