Answer:
460 ft^2 of carpet will be replaced
Step-by-step explanation:
You need to find the area of the room and then take away the area of the six bookcases
<u>Area of the room</u>
20*20=400ft^2
35-20=15ft
(15*20)/2=150ft^2
400+150=550ft^2 total room area
<u>Area of bookcases</u>
2.5*6*6=90ft^2 total bookcase area
<u>room area - bookcase area = carpet area</u>
550-90=460ft^2
Answer:
acceleration,A = 7
Step-by-step explanation:
F = kA
First expression: 45 = 5k, k = 9
therefore, when F = 63, A = 63/9 = 7

Let's compare the expressions in the given options to the value we got above:
Option 1: 3*3⁶
= 3*729 = 2,187 (this is equal)
Option 2: 3⁷ ÷ 3⁰
= 2,187 ÷ 1 (recall: x⁰ = 1, therefore, 3⁰ = 1)
= 2,187 (this is equal)
Option 3: 3³ * 3⁴
= 27*81 = 2,187 (this is equal)
Option 4:

There are 9 number cards from 2 to 10 in a deck of cards.
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
(2-10) has one 9
There are 4 nines in a deck of 52 cards. We know that 4 x 9 = 36.
The chance or probability of taking out a 9 is (36/52).
Reducing this fraction to the lowest terms we get 9/13.
