The number of small tiles are needed is 300 tiles.

<h3>Number of tiles needed</h3>

Using area of rectangular formula

Area of the room = length(l) × breadth (b)

Area of the room=300 cm×180 cm

Area of the room=54,000 cm²

Number of tiles needed = Area of rectangular region / Area of one tile

Number of tiles needed=54,000/180

Number of tiles needed=300 tiles

Therefore the number of small tiles are needed is 300 tiles.

Which expression is equivalent to <img src="https://tex.z-dn.net/?f=-4x%5E%7B-5%7D%20x%5E%7B0%7D" id="TexFormula1" title="-4x^{-

Ber [7]

The expression that is equivalent to the given expression is -4x^-5

<h3>How to determine which expression is equivalent to the given expression?</h3>

The expression is given as:

$-4x^{-5} x^{0}$

Rewrite properly as

-4x^-5x^0

Express as products

-4x^-5 * x^0

The value of x^0 is 1

So, we have:

-4x^-5 * 1

Evaluate the product

-4x^-5

Hence, the expression that is equivalent to the given expression is -4x^-5

Part A: Solve A = (x + 23) for x. (4 points) Part B: Determine the value of x when A = 108. (2 points) Part C: Solve -np - 90 &g

Galina-37 [17]

<span>Part A: Solve A = (x + 23) for x.

A = x + 23

=> A - 23 = x + 23 - 23

=> A - 23 = x

=> x = A - 23 <------- answer

Part B: Determine the value of x when A = 108

Replace the value of A in the expression x = A - 23

x = 108 - 23 = 75

x = 75 <------- answer

Part C: Solve -np - 90 > 30 for n.

-np - 90 > 30

=> -np + np - 90 >30 + np

=> - 90 > 30 + np

=> -90 - 30 > 30 - 30 + np

=> -120 > np

=> np < - 120 <----- answer

7/10 of 120 and show work pls

slavikrds [6]

When it says 7/10, it actually means 70%, so you have to find 70% of 120.
<span>
70 % of 120
= 70% x 120
= (70/100) x 120
= (8400/100)
= 84
