Answer:

Sydney, Nova Scotia

Step-by-step explanation:

Out of all 3 Sydney, Nova Scotia would be the coldest because -23 degrees is lower than -21 and -22. When using a thermometer the lower it is the colder, so Nova Scotia would be your answer.

Answer:

The slope is 2.

Step-by-step explanation:

The formula for slope is m = (y2-y1)/(x2-x1)

If we choose the points (0,2) and (1,4) we can plug these into our slope equation.

(4 - 2) / (1 - 0) = 2/1 = 2

In 2000, a company had 1147 stores nationwide. By 2002, this total had grown to 1542. If the number of stores continues to gro

mr_godi [17]

12226 stores will be there in 2016

Solution:

The growth function is given as:

$y = a(1+r)^t$

Where,

y is the future value

a is the initial value

r is the growth rate

t is the number of years

From given,

In 2000, a company had 1147 stores nationwide

By 2002, this total had grown to 1542

Therefore,

y = 1542

a = 1147

t = 2000 to 2002 = 2 years

r = ?

Substituting we get,

$1542 = 1147(1+r)^2\\\\(1+r)^2 = \frac{1542}{1147}\\\\(1+r)^2 = 1.34437$

Taking square root of both sides

$1+ r = 1.1594\\\\r = 1.1594 - 1\\\\r = 0.1594$

If the number of stores continues to grow exponentially at the same rate, how many stores will there be in 2016?

Therefore,

y = ?

a = 1147

r = 0.1594

t = 2000 to 2016 = 16 years

Substituting we get,

$y = 1147(1 + 0.1594)^{16}\\\\y = 1147(1.1594)^{16}\\\\y = 1147 \times 10.6593\\\\y = 12226.3311 \approx 12226$

Thus 12226 stores will be there in 2016

Write the fraction 7/1000 as a percent to the nearest hundredth of a percent.

Hunter-Best [27]

You're answer is: 0.7%

Explanation:

To get the answer, simply multiply 100 by 7/1000 which would give you 0.007. Then once you get 0.007 you'll need to multiply again by 100. Which would give you 0.7%

7/1000×100=0.007

0.007×100=0.7%

That being said, 0.7% is the correct answer.
