The money in this account will earn 6% interest, which is compounded quarterly. Which model would be appropriate to determine how many years, y, Mr. Andrews will have to wait until he has earned enough money in this account to buy the violin? A = P ( 1 + r n ) n t A = amount of money accumulated after n years, including interest, P = principal amount (the initial amount deposited), r = annual rate of interest, n = number of times the interest is compounded per year, and t = number of years the amount is deposited

The lifespan of a hamster is 4 years less than that of a rabbit. The lifespan of a raccoon is 2 times that of the hamster. If the total lifespan of the animals is 24 years, calculate the longevity for the rabbit.

Answers

Answer:

9 years

Step-by-step explanation:

Let

Lifespan of rabbits = x

Lifespan of hamster = x - 4

Lifespan of raccoon = 2(x - 4)

Total lifespan of animals = 24

Total = rabbits + hamster + raccoon

24 = x + (x - 4) + 2(x - 4)

24 = x + x - 4 + 2x - 8

24 = 4x - 12

24 + 12 = 4x

36 = 4x

x = 36/4

x = 9 years

longevity for the rabbit = 9 years

Lifespan of rabbits = x = 9

Lifespan of hamster = x - 4

= 9 - 4

= 5

Lifespan of raccoon = 2(x - 4)

= 2(9 - 4)

= 2(5)

= 10

Total lifespan of animals = 24

Five numbers have a range of 14. Four of the numbers are 20, 22, 31 and 25. Work out the two different possible values for the fifth number.

Answers

Answer:

17

34

Step-by-step explanation:

Range is the difference between the highest and lowest values of a set of observations

Range = highest value - lowest value

the missing number can either by the highest value or the lowest value. this is because none of the numbers given when subtracted from each other would give a value of 14

let x = missing number

14 = x - 20

x = 20 + 14 = 34

or

14 = 31 - x

x = 31 - 14

x = 17

there are 3 red, 1 blue and 2 purple marbles in a bag. once a marble is selected, it is replaced. what is the probability of picking a purple and blue? P (purple and blue)

Answers

Answer:

here

Step-by-step explanation:

There are total (3 purple + 4 orange + 1 green) = 8 marbles in the bag . Now, 2 marbles out of 8 marbles can be selected in C(8,2) = 8!/2!6! = 28 no. of ways . And 2 purple marbles out of 3 purple marbles can be selected in C(3, 2)

= 3!/2! 1! = 3 no. of ways. Hence the required probability = 3/28

Answer:

1/15

Step-by-step explanation:

3 red, 1 blue, 2 purple

P of purple and blue is the

P of purple * P blue =

(2purple/(3+1+2) )* (1blue/ (3+1+2-1)) = (2/6) * (1/5) = 2/30 = 1/15

Actually Welcome to the concept of Radioactive decay.

N(t) = 72(1/2)^22/11

In a new scale drawing of the same room, the length of the room measures 4 inches. What is the scale of the new drawing?

Answers

Answer:

6 feet = 1 inch

Step-by-step explanation:

The actual length of the room = 24 feets

The new scaled lengtb of the room = 4 inches

The scale of a drawing = actual length / scaled or model length

Hence, scale used = 24 feet / 4 inch = 6 feet / 1 inch

The scale of the new drawing :

6 feet : 1 inch

6 feet length of actual room length is equivalent to 1 inch length on the drawing

Answers

Answer:

Step-by-step explanation:

Let's baby-step this to make it easy, ok? Begin by getting rid of all the fractions, which means we will eliminate the 3 from the 1/3 by multiplying both sides be 3:

[tex]3V=\pi r^2 h[/tex]

If we want to eventually isolate the r, we need to move the h and the pi. Do this by division, since each of these is multiplied by r-squared. Doing that gives us:

[tex]\frac{3V}{\pi h}=r^2[/tex]

Lastly, to undo a square, we have to take the square root. We will do that for both sides of the equals sign:

[tex]+\sqrt{\frac{3V}{\pi h} }=r[/tex]

The positive is out front there to indicate that we don't want the negative value since distance is a measure that will never be negative.

Which way is the wind blowing in relation to the land and ocean?

Answers

Answer: Hope This Helps!

Step-by-step explanation:

This wind happens to be the sea breeze. The sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.

Answer:

When the air mass above the land becomes cooler than the air mass over water, the wind direction and convective cell currents reverse and the land breeze blows from land out to sea.

Answers

Answer:

35% or 35/100

Step-by-step explanation:

Gage Millar, Algebra 2 tutor

Choosing a number LESS than (not equal to 8) is 7/10 (1,2,3,4,5,6,7)

Chosing an even number is 5/10 (2,4,6,8,10)

so just multiply 7/10 x 5/10 to get 35 over 100, or a 35% chance
