Which set of statements would describe a parallelogram that can always be classified as a rhombus?

I. Diagonals are perpendicular bisectors of each other
II. Diagonals bisect the angles from which they are drawn
III. Diagonals form four congruent isosceles right triangles

Answer:

m = 35, n = 110

Step-by-step explanation:

Opposite angles are congruent , then

2m = 70 ( divide both sides by 2 )

m = 35

Consecutive angles are supplementary, that is sum to 180° , so

70 + n = 180 ( subtract 70 from both sides )

n = 110

Answer:

120, 15

Step-by-step explanation:

Answer:

15,120

Step-by-step explanation:

x-axis-15(read vertically)

y-axis-120(read horizontally)

Answer:

I'm sure you mean miles, but the car will travel 135 mites.

Step-by-step explanation:

(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Answer: 49.45

Step-by-step explanation:

From the information, we are informed that June was thinking of a number and then doubles it and gets and gets an answer of 98.9.

Let the number be represented by x.

Since she doubles it, thus implies that:

2x = 98.9

x = 98.9 / 2

x = 49.45

The number is 49.45

Answer:

y = -5x -8

Step-by-step explanation:

The equation is y = mx + b so just plug it all in

y = -5x + (-8)

which is

y = -5x -8

Answer: 59/3k+14

Step-by-step explanation:

Answer:

OD

Step-by-step explanation:

The zero x=8 will make the factor (x-8) = 0 and the zero x=3 will make the factor (x-3) = 0.

so it's (x-8) and (x-3)

Answer:

Pretty sure it's $70.  

Step-by-step explanation:

The first thing you need to do is round to the nearest ten. To do that you see if $28 is closer to $20 or $30. And it is closer to $30. The see if $32 is closer to $30 or $40. And it's closer to $30. Then you subtract $132 minus $30 minus $30. And you get $72. If they are asking what the nearest ten is for the answer, then it would be $70.

Answer:

70

Answer:

[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Step-by-step explanation:

From the question we are told that the expression [tex]ln(y √x/z[/tex]

[tex]in (y\sqrt{\frac{x}{y}})[/tex]

[tex]in(y)+in(y\sqrt{\frac{x}{y}})[/tex]

[tex]in(xy)=in(x)+in(y)[/tex]

[tex]in(xy)=in\frac{x}{z} ^1^/^2 +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(\frac{x}{z}) +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(x)-in(z) +in(y)[/tex]

[tex]in(xy)=\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Mathematically

[tex]in (y\sqrt{\frac{x}{y}}) =\frac{1}{2} in(x)-\frac{1}{2} in(z) +in(y)[/tex]

Answer:

It is a proportional relationship

Step-by-step explanation:

Here, we want to know if the relationship is proportional or not

Looking at the table, we can see that every value of x multiplied by 4 will

give y

In simpler terms;

y = 4x

Hence, we have established that there is a proportional relationship between the x and y values

Answer: The combined amount of kids and adult meals sold = 36

Step-by-step explanation:

Let the number of kids meals sold = 5x and the number of adult meals = 4x

Since total kids meals sold = 20

Then, 5x= 20

⇒ x =4

Adult meals = 4(4) = 16

Combined meals sold  =  kids meals + Adult meals

= 20+ 16

= 36

Hence, the combined amount of kids and adult meals sold = 36

Answer:

[tex]\huge\boxed{x=23}[/tex]

Step-by-step explanation:

In order to find the value of x that makes m || n, we need to note something.

When two parallel lines are cut by a transversal, their angle measures will be the same.

Therefore, in order for m and n to be parallel, their two angles listed must be equivalent.

So, we can set these expression equal to each other and solve for x.

Therefore, x=23.
