Answer:

12 quarters

Step-by-step explanation:

number of quarters ---------x

number of dimes ------------y

therefore, x + y = 37---------------times 10 both sides --------10x + 10y = 370-------equation 1

              0.25x + 0.1y = 5.5 -----times 100 both sides -------25x + 10y = 550 ------equation 2

equation 2 minus equation 1 is 25x + 10y - 10x - 10y = 550 - 370 ------ 15x = 180 -------x = 12

there are 12 quarters

The mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents the average distance between each data value and the mean.

The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset.

Mean = 312. 9

absolute deviation = 0.19

Hence,the mean and mean absolute deviation of this set of data will be 312. 9 and 0.19 respectively. The mean absolute deviation represents. Average distance between each data value and the mean.

Answer:

Midpoint is[tex](-25.15,10.2)[/tex]

Step-by-step explanation:

A line segment refers to line that has two endpoints.

Let [tex](a,b),(c,d)[/tex] be the endpoints of a line segment.

Midpoint of the line segment is given by [tex](\frac{a+c}{2} ,\frac{b+d}{2})[/tex]

Take the given points as follows:

[tex](a,b)=(-24.6,38.1)\\(c,d)=(-25.7,-17.7)[/tex]

Midpoint of a line segment [tex]=(\frac{-24.6-25.7}{2},\frac{28.1-17.7}{2})[/tex]

[tex]=(\frac{-50.3}{2} ,\frac{20.4}{2} )\\=(-25.15,10.2)[/tex]

Answer:

m = rise/run = 4/5.

Step-by-step explanation:

This line goes throught the "exact" grid intersections (-2, 0) and (3, 4).  As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise').  Thus, the slope of this line is m = rise/run = 4/5.

Step-by-step explanation: equilateral triangle, square, regular hexagon

In a regular tessellation 3,4,6 sides can be tessellating regular

polygon.

A normal tessellation is one made the use of only one regular polygon. A semi-normal tessellation uses or extra ordinary polygons. Triangles and squares, for example, shape ordinary tessellations and octagons and squares for a semi-normal tessellation.

First of all, there are handiest 3 normal tessellations which can be triangles, squares, and hexagons. To make a ordinary tessellation, the inner angle of the polygon has to be a diviser. that is due to the fact the angles need to be introduced as much as so it does now not leave any gaps.

A polygon having identical facets of identical lengths are known as everyday polygons. A ordinary polygon is a polygon that is equiangular i.e. all the angles are equal in measure and equilateral i.e. all facets have the equal length.

A line of symmetry is a line that can be attracted to divide a parent into same halves. A determine has line symmetry or reflection symmetry while it could be divided into identical halves that match. A discern has mirrored image symmetry if it could be meditated throughout a line and look exactly the same as it did earlier than the reflection.
