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.
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

8-(36/9)+99-(6x7)
8-4+99-42
4+57
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.

The hummingbird population on an island is declining at a rate of 1.4% per year. The population was 5500 in the year 2009.
What is the best prediction of the hummingbird population in the year 2016?
Enter your answer, rounded to the nearest integer, in the box.
The hummingbird population will be
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
[tex]P=5500(1-1.4\%)^7[/tex]
[tex]P=5500\times0.986^7\\P=5500\times0.90602\\P=4983.117\approx 4983[/tex]

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?
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 milesNumber 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 milesHence, Colton will have to ride 7.2 miles each day.

Answer:
x = 10
Step-by-step explanation:
From what we can see in the diagram, the smaller triangle dimensions were dilated by a factor of 3
So to get the dimensions of the smaller from the bigger or larger triangle, we proceed to divide what we have on the larger triangle by 3
Kindly note that we do this for the comparable sides
