Answer:
$937.50
Step-by-step explanation:
25 decrease 25% =
25 × (1 - 25%) = 25 × (1 - 0.25) = 18.75
18.75 × 50 = 937.50
Answer:
Step-by-step explanation:
7d – 8 = 3d + 8
7d - 3d = 8 + 8
4d = 16
d = 16 /4
d = 4
Answer:
1,352,078 ways
Step-by-step explanation:
In this question, we are to calculate the number of ways in which Mr Wonka can give his candy to a visitor.
This is a selection problem. Hence what we will be using is simply combination.
This is just a way of choosing 12 pieces of candy from a total of 23
Mathematically; 23C12 = 23!/(23-12)!12!
= 1,352,078 ways
A (t - 15)(t + 2)
b (w + 3)(w - 18)
c (2n - 1)(x + 2)
Answer:
(√9)^2x-1/2 = 1/81
3^2x-1/2 = 1/(3)⁴. (as √9 = 3)
3^2x-1/2 = 3^-⁴. (as 1/a^m = a^-m)
as base are equal exponents are equal
so 3 gets cancelled out
2x-1/2 = -4
(4x-1)/2 = -4
4x-1 = -8
x = -7/4
