Assuming the side lengths did not change, ...

Angle C would need to decrease by the same amount.
Angles B and D would each need to increase by the amount angle A decreased.

Answer:

Step-by-step explanation:

Given that quadrilateral ABCD is a rhombus.  Given that angle A decreases.

Since nothing is mentioned about the side of the rhombus, we see that side is not changing.

When angle A decreases, since opposite angles are congruent we must have equal decrease in C

Also opposite sides are parallel in a rhombus, hence adjacent angles are supplementary.

i.e. Whenever A decreases by a quantity say p, then B and D, the adjacent angles must increase by same quantity p so that the parallel lines property is preserved in the rhombus.

When a river​ flows, the strength or force of the river depends on how far the river falls vertically compared to how far it flo
strojnjashka [21]

The figure is missing. There are several problems with same wording but different numbers

Here, we can use:

  • Horizontal distance: 258 feet

  • Vertical fall: 56.0 feet

Answer:

  • Slope = 56.0 ft / 258 ft ≈ 0.217

Explanation:

The <em>slope</em> measures how the rate of change of the vertical distance (vertical fall) with respect to the horizontal distance.

There are several forms to express this with words, which represent the same formula. Here are some of them:

  • Slope = rise / run
  • Slope = vertical change / horizontal change
  • Slope = change in y / change in x
  • Slope = Δy / Δx
  • Slope = (y₂ - y₁) / (x₂ - x₁)

As said, all those forms mean the same; they are equivalent.

Here, we have vertical fall = 56.0 feet, and horizontal distance = 258 feet, and by specifications of the problem (in the hint) the slope must be positive. Thus, you get:

  • Slope = vertical fall / horizontal distance = 56.0 feet / 258 feet ≈ 0.217

Answer:

x = 13

Step-by-step explanation:

x and 167 are a linear pair, x plus 167 will equal 180

x + 167 = 180

x = 180 - 167

x = 13

To check: x + x + 167 + 167 = 360

x = 13

13 + 13 + 167 + 167 = 360

26 + 167 + 167 = 360

26 + 334 = 360

360 = 360

(6x3 + 3x² + 3) + (2x - 5x + 1)<br> the sum is?
laiz [17]
<h2>Answer:</h2><h2><em><u>8x^3 + 3x^2 - 5x + 4 is the answer.</u></em></h2>

Step-by-step explanation:

(6x^3 + 3x² + 3) + (2x^3 - 5x + 1)

6x^3 + 2x^3 = 8x^3

3x^2 + 0 = 3x^2

-5x + 0 = -5x

3 + 1 = 4

8x^3 + 3x^2 - 5x + 4 is the answer because you have to put all the terms that were solved together. This will lead to 8x^3 + 3x^2 - 5x + 4. And, standard form is ax^2 + bx + c. So, 8x^3 + 3x^2 - 5x + 4 is the answer.

<em><u>8x^3 + 3x^2 - 5x + 4</u></em>

<em><u></u></em>

Hope this helped,

PLS help me fast!!!!
Radda [10]

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the box plot shows the number of books sold each day at a store for 80 days.

A box plot is drawn with end points at 0 and 16.  It means minimum value is 0 and maximum is 16.

The box extends from 2 to 12. It means first quartile is 2 and the third quartile is 12. A vertical line is drawn inside the box at 7, it means median is 7.

He have to find the number of days in which the bookstore sell 2 to 12 books.

2 is first quartile and 12 is third quartile, we know that

Q_1=25\%

Q_3=75\%

Q_3-Q_1=75\%-25\%=50\%

The data lies between Q₁ and Q₃ is 50% of the data.

80\times \frac{50}{100}=40

The bookstore sell 2 to 12 books in 40 days.

Therefore, the correct option is 1.
