Answer:
33 1/3% decrease
Step-by-step explanation:
The original area is (6in)(10in) = 60 in². The reduced area is (5in)(8in) = 40 in². Then the change in area is ...
((new value)/(old value) -1) × 100%
(40/60 -1)×100% = -1/3×100% = -33 1/3%
The area decreased by 33 1/3%.
Hey there!
4(u + 5) - 2u
DISTRIBUTE 4 WITHIN the PARENTHESES
= 4(u) + 4(5) - 2u
= 4u + 20 - 2u
COMBINE the LIKE TERMS
= (4u - 2u) + (20)
= 4u - 2u + 20
= 2u + 20
Therefore, your answer is: 2u + 20
Good luck on your assignment & enjoy your day!

Is it asking how many she began with before she sold them? If so, then I think at the beginning she started out with 40. I think she had 40 because she sold half, and when you divide 40 by 2 it divides perfectly giving you 20. Then add 16 to that and you come out with 36.
The surface area of the cone is: A. 184π units².
<h3>What is the Surface Area of a Cone?</h3>
Surface area of a cone = πr(l + r), where r is the radius and l is the slant height.
Given the following:
- Slant height (l) = 15 units
- Radius = (r) = 8 units
Surface area of a cone = π8(15 + 8)
Surface area of a cone = 184π units²

Answer:
The answer to your question is Volume = 36000π cm³ in terms of π
Volume = 113040 cm³
Step-by-step explanation:
Data
Volume of a ball = 4/3 πr³
radius = 30 cm
π = 3.14
Process
1.- Substitute the values given in the formula
Volume = 4/3 π(30)³
2.- Simplification
Volume = 4/3π(2700)
Volume = 36000π cm³ in terms of π or
Volume = 36000(3.14) = 113040 cm³
