Mario claims that a rhombus is sometimes a square, but a square is always a rhombus. Is he correct? Explain your answer

That is correct.This is because a square has all the elements a rhombus has.A rhombus has 4 equal sides,just like a square does.And,a rhombus can't always be a square becase a square also contains 4 equal angles,while a rhombus doesn't.

Rhombuses are a type of parallelogram, which means their opposite sides are always parallel, and their opposite angles are always equal. A square is the only type of rhombus where all four angles are equal, and the only rhombus that also meets the definition of a rectangle (all angles are 90 degrees).

Answer:

You need 30 total weeks to win at least 65% games

Step-by-step explanation:

Team have played = 20 games

Number of winning games = 3

Let x represents the number of additional weeks.

You have won 3 games per week. Therefore you will win 3x additional games.

We know that 65% = 0.65

Therefore,

3+3x/20+4x = 0.65

By cross multiplication:

3+3x= 0.65(20+4x)

3+3x = 13+2.6x

Combine the like terms:

3x-2.6x = 13-3

0.4x=10

4x/10 =10

4x = 10*10

4x=100

Divide both sides by 4

4x/4 = 100/4

x = 25

since you have already played 5 weeks...you need to play 25+5 = 30 weeks.

Therefore you need 30 total weeks to win at least 65% games....

The scale on a map shows that 200 miles is represented by 5 inches on a map. Which proportion can be used to find the distance

Ivenika [448]

Answer:

A proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps:

200 miles ... 5 inches

50 miles ... x inch = ?

200 * x = 5 * 50

x = 5 * 50 / 200

x = 1.25 inch

The correct result would be x = 5 * 50 / 200.

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

boyakko [2]

Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)

What is the dimension of a rectangle if the perimeter is 198

AfilCa [17]

Answer:

Length = 49.5 unit and width = 49.5 unit

Step-by-step explanation:

Given as , Perimeter of rectangle = 198 unit

so ,as Perimeter of rectangle = 2× ( Length + width)

Or, 198 = 2 × (Length + width)

Or, $\frac{198}{2}$ = length + width

So, length + width = 99 unit

Now to make area maximum

Length × width = maximum

Or, (99 - width ) × width = maximum

99 Width - width² = maximum Let width = W

Now differentiate both side with respect to W

D(99W - W²) $\frac{D(99w - w^2)}{Dw}$ = 0 as, constant diff is 0

So, 99 - 2w = 0

Or, w = $\frac{99}{2}$

Or, w = 49.5 unit and L = 99- 4905 = 49.5 unit Answer
