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.

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

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 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]

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

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.

given f(x)=50+30x, find f(1), f(2), and f(3)
Please help
The numbers inside the parentheses are the x values. Replace x with each number and solve.
F(1) = 50 + 30(1)= 50+ 30 = 80
F(2) = 50 + 30(2)= 50 + 60 = 110
F(3) =!50 + 30(3)= 50 + 90 =140
The value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = 50 + 30x
The value of the function at x = 1, will be
f(1) = 50 + 30 × 1
f(1) = 50 + 30
f(1) = 80
The value of the function at x = 2, will be
f(2) = 50 + 30 × 2
f(2) = 50 + 60
f(2) = 110
The value of the function at x = 3, will be
f(3) = 50 + 30 × 3
f(3) = 50 + 90
f(3) = 140
Thus, the value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

original price is $240
Answer:
$240
Step-by-step explanation:

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.

A new car is purchased for 22300 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 7700 dollars?
Answer:
13, i think.
Step-by-step explanation:
use the equation: p( 1 - 7.5/100)^r
p= original amount
r = years
sub in numbers
22300 ( 1- 7.5/100)^r
just sub in different numbers for r till you get closest to your answer
After 13 years the value of the car would be $7700
What is an exponential decay?"It describes the decrease in an amount by a consistent percentage rate over a period of time."
What is exponential decay formula?"f(t) = a(1 - r)^t , where t is time, a is the initial value and r is the rate"
For given example,
initial value of the car (a) = 22300
The value of the car depreciates at 7.5% per year.
So, the rate (r) = 7.5%
We can write 7.5 percent as,
7.5% = 7.5/100
= 0.075
So, r = 0.075
Let 't' represents the number of years
We need to find the number of years when the car value is 7700 dollars.
y = $7700
Using the formula of exponential decay,
⇒ y(t) = a × (1 - r)^t
⇒ 7700 = 22300 × (1 - 0.075)^t
⇒ 0.3453 = (0.925)^t
⇒ t = 13.63
⇒ t ≈ 13
Therefore, after 13 years the value of the car would be $7700

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
