It is basically an incomplete question. I am answering the question based on my research and knowledge. "The multiplication property of exponents only holds when the numbers being multiplied have the same base. Since the bases are different, the expression cannot be simplified any further" is the response that would be best for Mark to give.

Riya is applying mulch to her garden. she applies it at a rate of 250 , 000 cm 3 250,000 cm 3 250, comma, 000, start text, space
Tatiana [17]

The rate in

\frac{ {m}^{3} }{ {m}^{2} }  \: is \:0.25\frac{ {m}^{3} }{ {m}^{2} }

<h3>How to find rate is riya applying mulch in m^3/m^2 ?</h3>

given that riya applies it at a rate of 250,000 cm^3 of mulch for every m^2 of garden space.

we already know that 1m = 100cm.

so, each side of this cube is 100cm in length.

so,100 \times 100 \times 100 \: {cm}^{3}  \: in \:  {m}^{3}

To find what is the volume in cubic metres.

\frac{250000}{10000000}  =  \frac{1}{4}  = 0.25 \frac{ {m}^{3} }{ { m}^{2} }

so, the rate is0.25 \frac{ {m}^{3} }{ {m}^{2} }

Solve the system of equations below by graphing.
Katen [24]

(0.5, 1.3) is the correct answer

Step-by-step explanation:

Given equations are:

y = 4x-0.8\ \ \ Eqn1\\2x+y-2.3=0\ \ \ Eqn2

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer

A regular decagon has 10 sides. How many reflectional symmetries does a regular decagon have?
lina2011 [118]

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.

For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.

There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.

Answer: 27.44 % decrease in gas prices

Step-by-step explanation: First subtract 2.15 by 1.56 to get 0.59

then divide it by the starting value which is 2.15

0.59 divided by 2.15 is  approximately 0.2744

then multiply times 100 to get 27.44 %
