The weight of a baby dog on day one is 5 kilograms. Every day, the dog grows an additional 0.1 kilograms. How heavy the dog is after 10 days?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The weight of the dog after 10 days is 5.9 kg.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Weight of the baby on day one = 5 kg
This can be written as,
1 day = 5 kg
The dog grows 0.1 kg each day.
This means,
On the 2nd day, we get,
2 days = 5 + 0.1
2 days = 5.1 kg
The expression for the weight of the dog on n days can be written as,
n days = 5 + (n -1) x 0.1 _____(1)
Now,
After 10 days we get,
n = 10
From (1) we get,
10 days = 5 + (10 - 1) x 0.1
10 days = 5 + 9 x 0.1
10 days = 5 + 0.9
10 days = 5.9 kg
Thus,
The weight of the dog after 10 days is 5.9 kg.

Step-by-step explanation:
The combined ages of megan and kyle are 27. if kyle is twice as old as megan, how old is kyle.
kyle is 18 and megan is 9, because 9 + 18 = 27 and 27 / 3 = 9. hope this helps :)
Answer:
Kyle's age = 18 years
Step-by-step explanation:
Let Megan's age = x
Kyle's age = 2x
Combined ages of Megan and Kyle = 27
x + 2x = 27
3x = 27 {Divide both sides by 3}
3x/3 = 27/3
x = 9
Megan's age = 9 years
Kyle's age = 2 * 9 = 18 years

Find 18.5% of 500- I couldn’t seem to figure this one out for some reason I dunno
Answer:
92.5
Step-by-step explanation:
18.5
[tex] \frac{18.5}{100} \times 500 \\ \\ [/tex]
100 times 5 is 500
so 100 is cancelled and 500 becomes 5
therefore 18.5 times 5 is equal to 92.5
Answer:
92 1/2 or 92.5
Step-by-step explanation:
how to solve?
Put it into a percent proportion :D!
Percent proportion is is/of=%/100 or a/w=p/100
The a stands for "part"
and the w stands for "whole"
p stands for "percent"
Is/of=%/100 will help you figure it out if it's in a mathmatical sentence.
Since they did NOT give you what the "is" is, you put the variable "a"
a/ =
Next,
Since it said "of"
You put of underneath the unknown number "is" (a)
a/500=
Now put in the percent
a/500=18.5/100
Now cross multiply!
Then you should get 92.5!

The monthly fee is going to be $5 and she's playing for a month, so let's put that down-
5+
Now, we need to figure out how much she plays - since we don't know this, we put it as a letter, and since we're calculating the cost, we add this to the equation-
5+0.25*x
Therefor, the answer is C(x)=5+0.25x
If the plays for 4 hours, the equation would be 5+(0.25*4)

Michelle is scuba diving. Her position changes from -2.1m to -38.6m in 6 1/4 min. What is the average change in Michelle's position each minute?
Answer: 5.824 m / min
Step-by-step explanation:
Change in position = -2.1m to -38.6m
Distance = |-38.6 m - (-2.1m) |
=|-36.5| m
= 36.5 m
Time = [tex]6\dfrac14\ min=\dfrac{6\times4+1}{4}\ min[/tex]
[tex]=\dfrac{25}{4}\ min[/tex]
The average change in Michelle's position each minute = [tex]\dfrac{36.5}{\dfrac{25}{4}}\text{ m/min}[/tex]
[tex]=\dfrac{36.4\times4}{25}\text{ m/min}\\\\= 5.824\text{ m/min}[/tex]
Hence, the average change in Michelle's position each minute = 5.824 m / min

water flows through a pipe at a rate of 7 cubic meters per month. Express this rate of flow in gallons per minute. Round your answer to the nearest hundredth.
Answer:
0.04
Step-by-step explanation:
The rate of flow is 0.043 gallons per minute.
How to convert litres to gallons ?Divide by 0.264 to obtain litres from gallons and multiply by 0.264 to obtain in gallons from litres.
According to the given question
Water flows through a pipe at a rate of 7 cubic meters per month.
We know 1 cubic meter is = 1000 litre
∴ 7 cubic meters per is
= (7 × 1000) litre
= 7000 litre
= (7000 × 0.264) gallons
= 1848 gallons per month
Now 1 month is
= ( 1 × 30 × 24 × 60 ) minutes.
=43200 minutes
So in 43200 minutes 1848 gallons of water flows through that pipe
∴ In a unit minute or per minute it the rate of flow will be
= 1848/43200 gallons per minute
= 0.043 gallons per minute.
