Answers

Answer: 4983

Step-by-step explanation:

Initial population P=5500

Population declining at the rate of 1.4%

So, in the year 2010 population is

[tex]P=5500-5500\times1.4\%=5500(1-1.4\%)[/tex]

For the year 2011

[tex]P=5500(1-1.4\%)^2[/tex]

similarly, for the year 2016

no of years passed 2016-2009=7 years

Answer:

11

Step-by-step explanation:

For this, we need to follow PEMDAS (Parenthesis, exponent, multiply/divide, add/subtract). First, we do the parenthesis, this gets us 8 - 4 + 49 - 42. Since this is all addition/subtraction, we do it from left to right. 8-4 is 4. Now our equation is 4 + 49 - 42. 4 + 49 is 53. Now our equation is 53 - 42. That is 11. That means our answer is 11.

Colton wants to ride his bicycle 53.2 miles this week. He has already ridden 10 miles.
If he rides for 6 more days, what is the average number of miles he would have to ride
each day to meet his goal?

Answers

Answer:

About 7 miles a day?

Step-by-step explanation:

53.2-10= 43.2

43.2 divided by 6 is  about 7.6. I’m just in middle school though :)

Colton will have to ride 7.2 miles per day on other to hit his target.

Total miles to ride = 53.2

Miles ridden already = 10 miles

Number of miles left to ride = (53.2 - 10) = 43.2 miles

Number of days left to ride = 6 days

The average ride per day will be:

Number of miles left ÷ number of days (43.2 ÷ 6) = 7.2 miles

Hence, Colton will have to ride 7.2 miles each day.

Tom earns £10 an hour and his wife earns £2 an hour more than Tom. Write a formula for their total earnings T for h hours.

Answers

Answer:

The formula for total earning is T = £22h

Step-by-step explanation:

Given that:

Per hour earning of Tom = £10

Per hour earning of Tom's wife = £10 + £2 = £12

Let,

T represent their total earnings

h be the number of hours

Total earnings = (Tom's per hour earning + His wife's per hour earning) * Number of hours

T = (£10+£12)h

T = £22h

Hence,

The formula for total earning is T = £22h
