Answer:

False.

Step-by-step explanation:

The definition of a rectangle is that it has 2 pairs of congruent opposite sides.

When a rhombus has to be equal in ALL sides.

Another proof is that a rectangle have 4 90 degree angles.
Whilst a rhombus DOES not have a single right angle no matter the case.

A more advanced proof would be if the diagonals would be perpendicular or if the diagonals would bisect two angles of a rhombus.
Whilst a rectangle’s diagonal are only congruent, not neccisalry perpendicular or bisects two angles.

Answer: True

Step-by-step explanation: A rectangle is a parallelogram with all its interior angles being 90 degrees. A rhombus is a parallelogram with all its sides equal. This means that for a rectangle to be a rhombus, its sides must be equal.

Hello,

oksano4ka [1.4K]

It took him 9.92 hours to complete the journey.

Step-by-step explanation:

Given,

Distance traveled = 50 miles

Distance traveled on horse = $\frac{50}{2}=25\ miles$

Distance traveled on foot = 25 miles

Speed while riding = 9 miles per hour

Distance = Speed * Time

Time while riding = $\frac{Distance}{Speed}$

Time while riding = $\frac{25}{9}=2.78\ hours$

Speed while waling = 3.5 miles

Time = $\frac{25}{3.5}=7.14\ hours$

Total time = 2.78+7.14 = 9.92 hours

It took him 9.92 hours to complete the journey.

A rock has a mass of 84 grams and a volume of 12 cc what is density?

Firlakuza [10]

The formula for density is:

Mass/Volume, or in other terms, mass divided by volume.

So, lets look at our numbers:
We know our mass is 84 grams, and our volume is 12 cc. So, all we need to do is divide 84 by 12, which is 7.

So, the density is 7.

How to find the scale factor of two triangles

BabaBlast [244]

Answer:

Here's how to do it.

Step-by-step explanation:

The two triangles must be similar, that is, corresponding angles must be equal, as in the diagram below.

1. Find a corresponding pair of sides

Assume that ∆ABC is the original and ∆DEF is its scaled image.

Then, AB and DE are corresponding sides, with lengths of 8 and 12 units , respectively.

2. Set up a ratio

Ratio = side length in image/side length in original = 12/8

3. Simplify the ratio

The simplified ratio is the scale factor (SF).

SF = 12/8 = 3/2 = 1.5

The scale factor is 1.5.

Simplify the expression <br> 3(9+4x−5)<br> 3(9+4x−5)<br> .

Alik [6]

12x+12 because you do the distribution property and this is how 3*9=27 3*4x=12x 3*-5=-15 27-15 = 12 so 12x+12 would be the answer it is really simple.
