Answer:

5 kg

Step-by-step explanation:

To solve this problem, we can use the rule of three.

In fact, we know that:

- 1 kilogram is equivalent to 2.2 pounds

- The ratio between the mass in kilograms and in pounds is constant for every value of the mass

- Therefore, the mass in kilograms corresponding to 11 pounds can be found by writing the following equation:

$\frac{1 kg}{2.2 p}=\frac{x}{11 p}$

Where

x is the mass in kilograms corresponding to 11 pounds.

Solving the equation for x, we find:

$x=\frac{(11p)(1kg)}{2.2p}=5 kg$

The points (10, -10) and (8, -10) fall on a particular line. What is its equation in slope-intercept form?

blondinia [14]

y = 0x - 10 is the equation in slope-intercept form given that the points (10, -10) and (8, -10) which fall on a particular line. This can be obtained by the formula of the slope-intercept form of the line.

<h3>What is its equation in slope-intercept form?</h3>

Linear equation is an equation that models a linear function.

In linear equation the variables are raised to the first power.

Example, Linear equation: 2x + 3, Not a linear equation: x² + 5

The graph of a linear equation contains all the ordered pair that are solutions of the equation.

The equation of a line is given by,

y = mx + c, m is the slope of the equation, c is the y intercept

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ , y intercept is the y coordinate of the point where y crosses the y axis.

Here in the question it is given that,

The points (10, -10) and (8, -10) fall on a particular line.

We have to find the equation in slope-intercept form.

Slope of the equation will be,

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$ ⇒ m = $\frac{-10 -(-10) }{8 -10 }$ ⇒ m = 0

y-intercept of the equation will be,

y = mx + c ⇒ -10 = 0 + c ⇒ c = -10

The equation of the line in slope-intercept form will be,

y = 0x -10

Hence y = 0x - 10 is the equation in slope-intercept form given that the points (10, -10) and (8, -10) which fall on a particular line.

Which statements are always true for a rectangle?

LekaFEV [45]

Answer:

True☆The diagonals are congruent.

Not always X All sides are congruent. (Only for rectangles that are also rhombus = a square!)

Not always X The diagonals of a rectangle are perpendicular to each other. (Counterexample: draw a really long rectangle with a tiny, tiny width...the x made by the diagonals is clearly not perpendicular!)

True☆ The opposite sides are parallel. (Bc rectangles are parallelograms, part of the definition)

True☆All angles are congruent. (All four angles are right angles--part of the definition)

In square YOLA, RL=5x+28 and RO=8X-11

Alexeev081 [22]

Answer:

RL=5x+28 and

RO=8X-11

diagonal of square bisect equally the side

:.5x+28=8x-11

11+28=8x-5x

39=3x

x=39/3=13

RY=RL=5x+28=5×13+28=93If the answer is 93, move to answer.

Question: The hypotenuse of a right triangle has a length of 14 units and a side that is 9 units long. Which equation can be use

kramer

Answer:

The hypotenuse is the longest side in a triangle.

a^2=b^2+c^2.

14^2=9^2+c^2.

c^2=196-81.

c^2=115.

c=√115.

c=10.72~11cm
