Answer:
10%
Step-by-step explanation:
Marked price of the shirt = Rs 1000
Sale price = Rs 900
Decease = (1000 - 900) Rs
= Rs 100
% decrease = decrease /marked price x 100%
That’s 100/1000 x 100%
0.1 x 100
10%
Answer:
see explanation
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius, here r = 9, thus
A = 4π × 9² = 4π × 81 = 324π ≈ 1017.9 units²
So what you would do is divide 12 by 3 which will get you for which means the total cost of 1 goldfish is $4

Answer:
D.) a+2b
Step-by-step explanation:
The integers 'a' and 'b' can be any, so you can choose a couple and evaluate these expressions to see what you get. For example, we can let a=1 and b=0. For these values, the offered expressions evaluate to ...
A) 3(0) = 0 . . . even
B) 1 +3 = 4 . . . even
C) 2(1+0) = 2 . . . even
D) 1 +2(0) = 1 . . . odd

<em>Additional comment</em>
These rules apply to even/odd:
- odd × odd = odd
- odd × even = even
- even × even = even
- odd + odd = even
- odd + even = odd
- even + even = even
Then A is (odd)(even) = even; B is (odd)+(odd) = even; C is (even)(whatever) = even; D = (odd)+(even) = odd.
Answer:
9
b³
Step-by-step explanation:
The 2 terms are like terms and can be combined, that is
