Answer:
B. 300
Step-by-step explanation:
Final figure volume = big cuboid volume - small cuboid volume
Volume of a cuboid = height x width x length
Final figure = (6 x 6 x 15) - (4 x 4 x 15)
Final figure = 540 - 240
Final figure = 300mm^2
Answer:
(b) $91.70
(c) 131 miles
Step-by-step explanation:
(b) $0.95 * 65
= $61.75
$61.75 + $29.95
= $91.70
(c) $125 ÷ $0.95
= 131.57894736
Rounded: 131 miles → *I think*
Answer:
Profit is revenue minus cost.
P(x) = R(x) – C(x) or
P(x) = 20x – (180 + 8x)
Distribute and combine like terms.
P(x) = 12x – 180
The breakeven point is when P(x) = 0.
0 = 12x – 180
180 = 12x
x = 15
They must sell 15 bracelets to break even.
Step-by-step explanation:
15 bracelets are required to break even.
180+ 8x=20x
180=12x
15=x
First you need to use the distributive property: 27(x+4)=-6
27x+108=-6
then you need to subtract 108 from -6 to
get x alone. 27x= 102
Lastly divide 102 by 27 to finally get x alone: x=3.777
the answer would be: x= 3.77 or 3.8
