Perform the square root function as normal, then apply the negative symbol to the answer. You should get -7.
Answer: A) yes,B)4.50n<105
Step-by-step explanation: should would make profit because you would take the answer you got from 12n > 105 + 4.50n to see work look below
12-4.50=7.5
7.5n>105
7.5/135=0.5
18*15=270
the answer for part b would be to see work look below
set up equation(4.50n<105)
4.50/105
answer is n<.042

Answer:
2 to 1
Step-by-step explanation:
Answer:
17) 288
18) $69.30
19) $56.00
20) $135.00
21) $132.00
22) $4,515
23) 6.9%
Step-by-step explanation:
17)(3 × 4) × (6 × 4) = 288
18) 18% + 8% + 100% = 126%.
$55 × 1.6 = $69.3
19) $32 × 175% = $56
20) 100% - 15% - 10% = 75%
$180 × 0.75 = $135
21) $3,300 × 0.04 = $13
22) 2.5% × 3 = 7.5%
$4,200 × 1.075 = $4,515
23) 58 × 1.069 = 62.002
Answer:
89.80 cm cubed
Step-by-step explanation:
A hemisphere is essentially just half of a sphere. We want to find its volume.
The volume of a sphere is denoted by: V = (4/3)π * r³, where r is the radius. That means the volume of a hemisphere, which is half a sphere, will be denoted by: V = (1/2) * (4/3)π * r³ = (2/3)π * r³.
Here, the radius is 3.5, so plug this in:
V = (2/3)π * r³
V = (2/3)π * (3.5)³ ≈ 89.80 cm cubed
