P = 2(L + W)
P = 58
L = 3W + 1

58 = 2(3W + 1 + W)
58 = 2(4W + 1)
58 = 8W + 2
58 - 2 = 8W
56 = 8W
56/8 = W
7 = W <=== width is 7 inches

L = 3W + 1
L = 3(7) + 1
L = 21 + 1
L = 22 <=== length is 22 inches

Ava is buying paint from Amazon. Ava needs 3⁄4 cup of blue paint for every 1 cup of white paint. Ava has 28 ounces of white pain
Drupady [299]

Answer:

21

Step-by-step explanation:

So we know the ratio is 3/4:1

So if she has 28 ounces of white pain, we can do 28*3/4=21. You could also do 28/4 (find out how much 1/4 of the value is) which is 7 and then multiply that by 3. What your basically doing is your putting it into 4 equal parts and then just multiplying by 3 since that's the amount of parts you need/have.

- Does the graph below represent a function? How do you know? please answer! ​
andrezito [222]

Answer:

No, the graph does not represent a function because it does not pass the vertical line test.

<h2>What is a function?</h2>

A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.

<h3>Vertical Line Test</h3>

To pass the test, any vertical line that we draw on the graph should only touch one point.

A vertical line is a straight line that goes from top to bottom.

  1. Draw vertical lines through points on the graph, like in the photo below.
  2. Check if any vertical lines touch more than one point.

The yellow vertical line touches two points, which is more than one. So, the graph does not pass the test. This graph is does not represent a function.

What is the length of the hypotenuse? Answer : 17
leonid [27]

Answer:

Below.

Step-by-step explanation:

Finding the hypotenuse:

Recall the formula of Pythagoras'theorem,

  • (Hypotenuse)² = (Base)² + (Perpendicular)²

Given that base = 8 and perpendicular = 15

Plugging the values,we obtain

  • H² = 8² + (15)²
  • H² = 64 + 225
  • H² = 289
  • H = √(17*17)
  • H = 17

Now applying trigonometric functions:

Recall SOHCAHTOA , it's very helpful.

Sin θ = Sin A = Opposite/Hypotenuse

  • Sin A = 15/17 ≈ 0.88

cos θ = cos A = Adjacent/Hypotenuse

  • cos A = 8/17 ≈ 0.47

Tan θ = tan A = Opposite/Adjacent

  • tan A = 15/8 ≈ 1.88

Note: The values in decimal are rounded to nearest hundredth.
