4 0

Answer:

144 pages

Step-by-step explanation:

3 hours * 60 = 180 minutes

40 pages / 50 minutes = x pages / 180 minutes

40/50 = x/180

cross multiply

50x = 40 * 180

50x = 7200

x = 7200 ÷ 50

x = 144

I believe it is neither

For one if you plug in either of them the first one is going to be negative 3. But if you use the second one then your answer would be -3+12= -10 but -3+12 is 9 so I would go with neither because I don't see how it's both

The perimeter of a rectangle is 34 units. Its width is 6.5 point, 5 units.
12345 [234]
<h3><u>Question:</u></h3>

The perimeter of a rectangle is 34 units. Its width W is 6.5 units.

Write an equation to represent the perimeter in terms of the length L, and find the value of L

<h3><u>Answer:</u></h3>

The length of rectangle is 10.5 units

<h3><u>Solution:</u></h3>

Given that,

Perimeter of rectangle = 34 units

Width of rectangle = 6.5 units

Let "L" be the length of rectangle

<em><u>The perimeter of rectangle is given by formula:</u></em>

Perimeter = 2(length + width)

<em><u>Substituting the values we get,</u></em>

34 = 2(L + 6.5)

Thus the equation is found

<em><u>Solve for "L"</u></em>

L + 6.5 = \frac{34}{2}\\\\L + 6.5 = 17\\\\L = 17 - 6.5\\\\L =10.5

Thus length of rectangle is 10.5 units

#4 find the value of x. Round answer to nearest tenth.
igomit [66]

Answer:

Step-by-step explanation:

From the given right angle triangle,

The unknown side represents the hypotenuse of the right angle triangle.

With m∠40 as the reference angle,

x represents the adjacent side of the right angle triangle.

4 represents the opposite side of the right angle triangle.

To determine x, we would apply

the Tangent trigonometric ratio.

Sin θ = opposite side/hypotenuse. Therefore,

Tan 40 = 4/x

x = 4/Tan 40 = 4/0.839

x = 4.8
