Answer: 55.0% decrease
Explanation: 100% =10
100% divided by 10 is 10%
10 divided by 10 is 1
So 1 is 10%
1 divided by 2 = 0.5 Is 10% divided by 2 = 5%
So 4.5 is 45%
100% - 45% = 55%
So there is a 55.0%decrease

1/y - 1/x = 1/60<br> 3y - 2x = 6 <br> (Simultaneous question)
Daniel [21]

1y - 1/x = 1/60 = x*y =60 = x=60/y

3y - 2(60/y) = 6

3y^2-120=6y

3(y^2-40-2y) =0

y^2-40-2y=0

y = 7.4


3(7.4)-2x=6

22.2-2x = 6

2x = -16.2

x = -8.1

Find two consecutive odd integers whose sum is 116 (and please have steps) thank you
matrenka [14]
It's 57 and 59
Call (n) is the first odd interger => the second odd interger is (n+2)
=> n + (n + 2) = 116 
=> n + n + 2 = 116 
=> 2n = 114 
=> n = 57 
First odd interger is 57 and the second odd interger is 59 .

Suppose customers in a hardware store are willing to buy​ N(p) boxes of nails at p dollars per​ box, as given by the following f
AleksAgata [21]

Answer:

a) -15 unites per dollar

b) -12 units per dollar

c) -18 units per dollar

Step-by-step explanation:

We are given the following in the question:

N(p) = 100-3p^2, 1\leq p \leq 4

where N(p) is the number of boxes of nails at p dollars per​ box.

a) average rate of change of demand for a change in price from ​$2 to ​$3.

Average rate of change =

\displaystyle\frac{N(3) -N(2)}{3-2}\\\\=\frac{100-3(3)^2-(100 - 3(2)^2)}{1}\\\\= -15\text{ units per dollar}

b) instantaneous rate of change of demand when the price is ​$2

Instantaneous rate =

N'(p) = \displaystyle\frac{d(N(p))}{dp} = -6p

N'(2) = -6(2) = -12

The instantaneous rate of change of demand when the price is ​$2 is decreasing at 12 units per dollar.

c) instantaneous rate of change of demand when the price is ​$3

Instantaneous rate =

N'(3) = -6(8) = -18

The instantaneous rate of change of demand when the price is ​$3 is decreasing at 18 units per dollar.
