Your grandparents started a savings account with $10,000 the day you were born. It earns 5% annually compounded monthly. How much will you have when you turn 18?
Answer: You will have $24,551.84 when you turn 18.
Step-by-step explanation:
Formula for accumulated amount earned in t years:
[tex]A=P(1+\dfrac{r}{12})^{12t}[/tex], where P = principal value, r = rate of interest
Given: P= $10000, r = 5% t = 18 years.
Substitute all values in formula, we get
[tex]A=10000(1+\dfrac{0.05}{12})^{12\times18}\\\\=10000(1.004167)^{216}\\\\=10000(2.45518445623)\approx24551.84[/tex]
Hence, you will have $24,551.84 when you turn 18.

The Children's play area at the Community pool holds a total of 3185 gallons of water it takes 2.5 hours to fill the pool with 1625 gallons of water how many gallons of water does the pool have after 1 hour find the unit rate
Answer:
650 gallons after 1 hour
Unit rate:650gallons/hour
Step-by-step explanation:
We are given that
Total capacity of pool=3185 gallon
In 2.5 hours water pool fill=1625 gallon
We have to find how many gallons of water fill in the pool after 1 hour and unit rate.
Using unitary method
1625 gallons of water takes time to fill the pool=2.5 hours
1 gallon of water takes time to fill pool=[tex]\frac{2.5}{1625}[/tex]hours
3185 gallon of water takes time to fill the pool=[tex]\frac{2.5}{1625}\times 3185[/tex] hours
3185 gallon of water takes time to fill the pool=4.9 hours
1 hours , water fill in pool =[tex]\frac{1625}{2.5}[/tex]gallons
1 hours , water fill in pool=650 gallons
Unit rate: How many volumes of water fill in 1 hour.
Unit rate=[tex]\frac{1625}{2.5}=650gallons/hour[/tex]

Nadia has a bag of different colored balloons. Without
looking in the bag, she selects a balloon, records its color
and puts it back in the bag. All balloons are equally likely to
De chosen. She performs 50 trials.
Number of times a blue balloon was chosen 22
Number of times a yellow balloon was chosen 7
Number of times a orange balloon was chosen 8
Number of times a purple balloon was chosen
13
Based on the data Nadia collected, what is the estimated probability, in
simplest form of choosing an orange balloon from the bag?
A.4/25. B. 4/50. C.8/100. D.50/8
Answer: A.4/25
Step-by-step explanation:
Number of trials that were performed = 50
Number of times a blue balloon was chosen = 22
Number of times a yellow balloon was chosen = 7
Number of times an orange balloon was chosen = 8
Number of times a purple balloon was chosen = 13
The estimated probability of choosing an orange balloon from the bag will be the number of times that an orange balloon was chosen divided by the total number of trials. This will be:
= 8/50
= 4/25
Answer:
Its 4/25 so its A.

A chess club plans to sell water bottles to raise $425
they already have $175
if they sell water bottles for $8 each, at least how many bottles do they need to sell in order raise enough money
which inequality represents the situation
Answer:
31
Step-by-step explanation:
I rounded it down thats it
The equality for this equation is
175 + 8b >/= 425
B = number of bottles required to sell. Now, I don't want to give you the answer but I can assist you in easily finding it. Subtract 175 from both sides
8b >/= 250
Now, divide at from both sides and remove the greater than mark which should mean that in the end it should look like it says
**edited** I mean divide 8 from both sides.
b = ?
That is the number of bottles they must sell, if it is a decimal, round it up because there is no such thing as a decimal number for selling water bottles.
The Capulet's are building a horse stall for their horse, Shaggy. The length, y, of the stall must be more than twice the width, x. However, they only have enough material to build 50 feet of fencing. Write the system of equations or inequalities used to solve it. Identify one option that would meet the criteria.
Answer:
y = 18
x = 7
Step-by-step explanation:
Since the Capulet's only have a total of 50 feet of fencing then that will also be the maximum perimeter of the fence and cannot exceed that value. Therefore, using the information provided we can conclude the following
y > 2x
y + y + x + x <= 50ft
2x + 2x + x + x <= 50ft
Now that we have these equations we can first solve for x and then solve for y
2x + 2x + x + x <= 50ft
6x <= 50ft ... divide by 6
x <= 8.33
y > 2 * 8.33
y > 16.66
Therefore, one possible value would be
Solve for Angles X&Y.
Answer:
y = 102°
x = 78°
Step-by-step explanation:
y = 900-(115+105+128+142+148+160)
y= 900-798
y= 102
x= 180-y
x= 180-102
x= 78
An item is regularly priced at $40 it is on sale for 60% off the regular price how much in dollars is discounted from the regular price
Answer:
$24 and $16
Step-by-step explanation:
well let’s go through this step by step.
we have $40 which is the regular price, but not only do you want to find what 60% of 40 is, but you want to find out how big the difference is between the 2, in dollars. But i believe we can do that.
So let’s just think. Do you know how to get a percent of something? If so, ignore this next part. If not, all you want to do is take 40 x 0.60. or whatever number you need. if it’s out of 100, that’s what you would do.
So now that we know how to get a percent of something, let’s find 60% of 40.
40 x 0.60 gives us 24, or in this case it’d be $24.
Great! we found the discount! now all we need to do is find out the difference.
All we need to do from here is take 40 - 24. what is 40 - 24?
16!
Now you’re done! the discount brings it down to $24 and the difference between the starting price and the discount price is 16 dollars.
i hope this was able to help you!
Vlad has 4 times as many blue marbles as green marbles. Which could be the number of blue marbles Vlad has?
Answer: A:16 marbles
Step-by-step explanation:
Because the number of blue marbles has to be four times as many as the number of green marbles, the blue marbles have to be a multiple of 4 because the number of marbles has to be a whole number.
Look at the options to see any option that is a multiple of 4.
That option is 16 so option A is correct.
Blue marbles being 16 means that green marbles are 4.

The sale price of an item is $180 after a 25% discount is applied. What is the original price of the item?
original price is $240
Answer:
$240
Step-by-step explanation:
.75*x=180
This equation is setup so we can find the value of the original price, since 25% is deducted, you can multiply x by 75% and set it equal to 180 since that is the resulting discounted price.
Matt has 3 different colored T-shirts and 2 different colored shorts
How many outfits can Matt make with these clothes?
Answer:
Step-by-step explanation:
3 x 2 = 6
Matt can make 6 different outfits with these clothes.
What are the Combinations?Combinations are the procedures used in mathematics to pick k things from n different items without replacement.
The following formula computes the combinations of k items from n:
(n, k) = n! / k!×(n-k)!
Given that Matt has 3 different colored T-shirts and 2 different colored shorts.
Matt can make 3 x 2 = 6 different outfits with these clothes.
This is because for each T-shirt color, he has 2 options for shorts, and he has 3 different T-shirt colors.
So for each T-shirt color, the number of outfit combinations is 2. And since he has 3 T-shirt colors, the total number of outfits is 3 x 2 = 6.

Х
Answer:
10.8
Step-by-step explanation:
By sine rule:
[tex] \frac{x}{ \sin 81 \degree} = \frac{7}{ \sin 40 \degree} \\ \\ x = \frac{7 \sin 81 \degree}{ \sin 40 \degree} \\ \\ x = \frac{7 \times0.9876883406 }{0.6427876097} \\ \\ x = \frac{6.91381838}{0.6427876097} \\ \\ x = 10.755992 \\ \\ x \approx 10.8[/tex]
Using the tangent formula we can write as,
Tan 40° = 7 / x
Tan 40 = 0.84
The value of x is 8.3 cm
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
A triangle with angle 40° angle 81° and 7 cm on on side of the triangle.
Using the tangent formula we can write as,
Tan 40° = 7 / x _____(1)
Now,
Tan 40 = 0.84
From (1) we get,
0.84 = 7 / x
x = 7 / 0.84
x = 8.3 cm
Thus,
The value of x is 8.3 cm
