A company wants to decrease their energy use by 16%.if their electric bill currently 2,2000 a month what will their be if they a

lyudmila [28]

The bill will be 18,480 if they are successful.

Step-by-step explanation:

Given,

Current bill of company = 22000

Energy usage to decrease = 16%

Amount of decreased usage = 16% of current bill

Amount of decreased usage = $\frac{16}{100}*22000$

Amount of decreased usage = $0.16*22000$

Amount of decreased usage = 3520

Bill after decreased usage = Current bill - Amount of decreased usage

Bill after decreased usage = 22000 - 3520 = 18480

The bill will be 18,480 if they are successful.

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?

boyakko [2]

Here, to find the average rate of change, you would simply divide 270 by 63. And when that is done, you would get a long decimal. 4.285714285714286

And since you obviously can't put in such a long decimal as your answer, you would round it instead. Once rounded, you would end up with 4.29 (because the number after 8 is five, which rounds up, which would turn the 8 to 9.)

ruslelena [56]

Answer:

46 housewives read all three magazines.

Step-by-step explanation:

Given:

n(A) = 150

n(B) = 200

n(C) = 156

n(A∩B) = 48

n(B∩C) = 60

n(A∩C) = 52

n(A∪B∪C) = 300

so we know the relation as:

n(A∪B∪C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) + n(A∩B∩C)

∴ n(A∩B∩C) = n(A) + n(B) + n(C) - n(A∩B) - n(B∩C) - n(A∩C) - n(A∪B∪C)

= 150 + 200+ 156 - 48 - 60 - 52 - 300

= 46

Hence the number of housewives that had read all three magazine is 46.
