Answer:

D. 4 $m^{2}$

Step-by-step explanation:

First find the area of 1 tile

= length * breadth

= 8 * 5

= 40 $cm^{2}$ = 40/10000 = 0.004

no. of tiles= 1000

therefore, total area of 1000 tiles = area of room= 1000*0.004

=4 $m^{2}$

Find the sum of the arithmetic sequence 1, 3, 5, 7, … , 99.

bezimeni [28]

The sum of the arithmetic sequence 1, 3, 5, 7, … , 99 is 2525

<h3>What is Sequence?</h3>

Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Given sequence is 1, 3, 5, 7, … , 99.

It is a arithmetic sequence, the difference between two consecutive terms will be same

d=3-1=2

first term a=1

l=last term =99

We need to find 99 is which term in the sequence

Aₙ = a + ( n - 1 ) d

99=1+(n-1)2

99=1+2n-2

99=2n-1

100=2n

Divide both sides by 2

50=n

Now we need to find the sum of 50 terms

Sₙ=n/2(l+d)

=50/2(99+2)

=25(101)

=2525

Hence, the sum of the arithmetic sequence 1, 3, 5, 7, … , 99 is 2525

Use the substitution method to solve the following system of equations: 3x + 5y = 3 x + 2y = 0 (1 point) (1, 1) (6, −3) (6, 1) (

PtichkaEL [24]

Step-by-step explanation:

Given.

$3x+5y=3$

$x+2y=0$

Take the second equation and subtract 2y to both sides.

$(x+2y)-2y=0-2y$

$x=-2y$

Substitute x into the first equation and simplify.

$3x+5y=3$

$3(-2y)+5y=3$

$-6y+5y=3$

$-y=3$

Invert.

$y=-3$

Substitute Y into your second equation.

$x+2y=0$

$x+2(-3)=0$

$x-6=0$

Add -6 to both sides.

$(x-6)+6=0+6$

$x=6$

Answer:

(6, -3)

BSE is square.

Let side be s

s=90ft

Diagonal be d

$\\ \tt\longmapsto s=\dfrac{d}{\sqrt{2}}$

$\\ \tt\longmapsto d=s\sqrt{2}$

$\\ \tt\longmapsto d=90\sqrt{2}$

$\\ \tt\longmapsto d=127ft$
