Statment 2 is the definition of the rhombus: all the three sides have equal length. 
Statment 4 triangle DOA similar to BOA by the SSS statement of similar triangles (AD=AB, proven from statement 1, AO is side of both triangles, BO=OD from statement 3). 
Statment 5: angle 1 equals angle 2 from statement 4 since they are corresponding angles of the two triangles DOA and BOA.

<span>Reason for Statement 2: Definition of a rhombus (all sides congruent).

AD, BC, CD and BA are all the sides of the figure.  Since it is a rhombus, they will all be congruent.

Reason for Statement 3: Diagonals of a rhombus are perpendicular to each other.

These two angles form a linear pair; their sum is 180.  Since they are congruent, this means the measure of each is 180/2=90.  This is because the diagonals of a rhombus are perpendicular to each other.</span>

butter and flour are mixed in the ratio 2:3. paul has 640 grams of butter and 880 grams of flour. how much more flour does he ne
madam [21]

Answer:

80g

Step-by-step explanation:

Here's why:

SO you have 2:3 ratio which means the ratio for grams of butter/grams of flour has to be 2:3.

So we set up the following equation:

2/3 = 640/x (solve for x)

x= 960g

960g is what you should have to get to ratio, but the question is asking how much more you need from the initial given flour.

So you need  (suppose x is the grams of flour you need)

x+880g = 960g (solve for x)

x=80g

The 2000 U.S. Census reports the populations of Bozeman, Montana, as 27,509 and Butte, Montana, as 32,370. Since the 1990 census
Nitella [24]
If the increase is x% per year, the multiplier each year is 1+x (expressed as a decimal).

Bozeman = 27,509·1.0196^t
Butte = 32,370·0.9971^t

where t is the number of years after 1990.

The volume of a cylinder is given by the formula mc023-1.jpg, where r is the radius of the cylinder and h is the height. Suppose
Simora [160]
Volume of a cylinder = π r² h

Given:
radius = (x+8)
height (2x + 3)

Volume of a cylinder = π * (x+8)² * (2x + 3)

V = π * (x+8)(x+8) * (2x+3)
V = π * (x² + 8x + 8x + 64) * (2x + 3)
V = π * (x² + 16x + 64) * (2x + 3)
V = π * (2x³ + 32x² + 128x + 3x² + 48x + 192)
V = π * (2x³ + 32x² + 3x² + 128x + 48x + 192)
V = π * (2x³ + 35x² + 176x + 192)
