Answer:
area=320m²
Step-by-step explanation:
perimeter=2(l+w)
72=2(l+16)
72/2=l+16
36=l+16
36-16=l
l=20m
area=l*w
=20*16
=320m²
Answer:
$49.572
Step-by-step explanation:
Given that :
Cost per disc = $18
Number of disc purchased = 3
Discount received = 15%
Sales tax = 8%
Original cost : cost per dic * number purchased
Original cost = $18 * 3 = $54
Discounted price = (100 - 15)% * $54
Discounted price = $45.9
Sales tax :
(100 + 8)% of $45.9
108% * $45.9
= $49.572
Total price = $49.572
1.
8 < x(7 - x)
We can now substitute the given values to see which one satisfies the inequality.
8 < 2(7 - 2)
8 < 10
A is the correct answer.
2.
D.
This lists all of the factors of 24.
Commutative property of multiplication is saying that if all the signs are multiplication signs, then no matter what order you multiply them in, it will always be the same answer. Ex: 3•5•5=75 if you change the order 5•3•5, it'll still equal 75
