rachel breaks up a large array into two smaller arrays. the two smaller arrays show 3 times five and 4 times 5. what was the lar

SVEN [57.7K]

Answer:

So the bigger array is 12 and 25

Step-by-step explanation:

Let's do a multiplication of this array first and Know it's result.

3 times five and 4 times 5. = (3*5) and (4*5)

= 15 and 20

Multiplying further gives us

= 15 * 20=300.

So to combine to get the bigger array.

We must get back 300 as the result of our product.

Let's multiply the row(x) with the row(x)

And the column (y) with column(y)

3 times five and 4 times 5.= 3*4 and 5*5

So the bigger array is 12 and 25

To check.

12*25 = 300

Proved.

Find the perimeter of the polygon. Round your answer to the nearest tenth.

dimulka [17.4K]

The perimeter of the polygon is 26.1 units.

To find the perimeter of the polygon.

<h3>What is polygon?</h3>

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. Thus, the line segments of a polygon are called sides or edges.

Given that:

Distance between points $(x_{1} ,y_{1} )$ , $(x_{2} ,y_{2} )$ is given by

$\sqrt{(x_{2} -x_{1} )^{2}+(y_{2} -y_{1} )^{2} }$

As per the graph,

point Q is (2,0)

point R is (4,5)

point S is (8,7)

point T is (6,4)

point U is (10,3)

QR= $\sqrt{(4 -2 )^{2}+(5 -0 )^{2} }=\sqrt{4+25} =\sqrt{29}$ $=5.38 units$

RS= $\sqrt{(8 -4 )^{2}+(7 -5 )^{2} }=\sqrt{16+4} =\sqrt{20}$ $=4.47 units$

ST= $\sqrt{(6 -8 )^{2}+(4 -7)^{2} }=\sqrt{4+9} =\sqrt{13}$ $=3.60 units$

TU= $\sqrt{(10 -6 )^{2}+(3 -4 )^{2} }=\sqrt{16+1} =\sqrt{17}$ $=4.12 units$

QU= $\sqrt{(10 -2 )^{2}+(3 -0 )^{2} }=\sqrt{64+9} =\sqrt{73}=8.54 units$

Perimeter refers to sum of lengths of all the sides.

Perimeter =5.38+4.47+3.60+4.12+8.54=26.1 units

So. the perimeter of the polygon is 26.1 units.
