Young has $150.00 in a savings account that earns 5%
interest, compounded annually.
What will the balance be after 1 year?
Round to the nearest cent.
S
Answer:
$157.50
Step-by-step explanation:
The equation you use for compound interest is:
\(A = P(1 + \frac{r}{n})^{nt}\\\)
where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
So for this question,
150 is our initial balance = P
5% is our interest rate = r
n = 1 because the interest is compounded annually per 1 year so 1 per year
t = 1 because we are calculating the balance after 1 year
Now we can plug these in and solve for the final amount (A).
\(A = 150 ( 1 + \frac{0.05}{1})^{1 * 1}\)
remember that 5% is 5/100 so we put 0.05 for r
\(A = 150 (1.05)^{1}\)
A = 150 (1.05)
A = 157.5

Answer the question below please!! :D
A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.
What is the measure of x?
5
3
9
2
Answer:
x=9
Step-by-step explanation:
x + x - 4 + x - 4 = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 9
Answer: x=9
Step-by-step explanation:
There are three sides 2 that are x-4 and 1 that is x. The equation would be
x+2(x-4)= 19 so you would simplify to get
X+2x-8=19 then 3x=27 then divide by three to get x=9
Part I – Simplifying Expressions

Part III – Solving Equations and Inequalities
Solve the equation x – 23.25 = 22.4
Solve 23 - 3n = 26.
Solve −2 − 5x ≥ 28
Answer:
73t + 15 & -16y - 2 // 3 & 4 // x = 45.65 & n = -1 & x ≤ -6
Step-by-step explanation:
Part 1:
13t(2+4)-5t + 15
use the distributive property and multiply your variable through the parentheses
( (13t x 2) + (13t x 4) ) -5t + 15
multiply the coefficient through
(26t + 52t) -5t +15
add the like terms within the parentheses first
78t - 5t + 15
add like terms as a whole since parentheses is done and simplify
73t + 15
-2(3y + 5) -2
apply the distributive property and multiply the coefficient
( (-2 x 3y) + (-2 x 5) ) -2
multiply through and add terms within parentheses
(-6y - 10y) -2
add like terms together within parentheses and then simplify the final expression
-16y - 2
Part 2:
apply the distributive property and solve normally each equation and see if the value of x given is true or plug in the x value that they give you and see when plugged in if the output is the same as the one shown
3. is true
plug in technique
8(1 + 5) = 48 (add like terms)
8(6) = 48 (multiply)
48 = 48 (check)
4. is true
plug in technique
2(-5) + 5 = -5 (multiply given value of x with coefficient)
-10 + 5 = -5 (add like terms and simplify)
-5 = -5 (check to see if true)
Part 3:
for all 3 equations, follow the order of operations or PEMDAS and simplify and combine like terms and solve for the given variable
a) x - 23.25 = 22.4 (add 23.25 to the other side and same side to get x alone)
x = 45.65
b) 23 - 3n = 26 (subtract 23 to get 3n alone from 26)
-3n = 3 (divide by -3 to get n alone from 3 --> 3/-3)
n = -1
c) -2 -5x ≥ 28 (add positive 2 to the other side of the inequality sign to get -5x alone)
-5x ≥ 30 (divide by -5 but since you are dividing by a negative you have to flip the sign)
x ≤ -6

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Barbara runs a lemonade stand to raise money for Barton Children's Hospital. Last weekend, she made 8 liters of lemonade to sell. Saturday was rainy, so she only sold 8 glasses. The weather was better on Sunday, so she sold 24 glasses. If each glass holds 200 milliliters, how many liters of lemonade does Barbara have left?
PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!
Answer:
1.6 liters of lemonade
Step-by-step explanation:
There are 1000 milliliters in one liter so she made 8000 milliliters of lemonade
Next we have to figure out how many milliliters of lemonade she sold each day:
Saturday: 200 milliliters of lemonade in a glass * 8 glasses = 1600 milliliters of lemonade sold
Sunday: 200 milliliters of lemonade in a glass * 24 glasses = 4800 milliliters of lemonade sold
1600 + 4800 = 6400 total milliliters of lemonade sold
Since there are 1000 milliliters in one liter, we have to divide 6400 by 1000:
6400 ÷ 1000 = 6.4 liters
Lastly, we have to subtract 6.4 from 8:
8 - 6.4 = 1.6 liters of lemonade
Hope this helps!

Step-by-step explanation:
Josiah kept track of how many songs of each genre were played in an hour from his MP3 player. The counts are displayed in the table below. He has a total of 1,500 songs on his player. Josiah predicted the number of rock songs on his MP3 player to be 300 songs. Which statements about his solution are true? Select three choices. Josiah’s Music Sample 1 Sample 2 R & B 5 R & B 4 Pop 4 Pop 3 Classical 3 Classical 5 Jazz 2 Jazz 4 Rock 6 Rock 4 Josiah’s work: StartFraction 10 over 20 EndFraction = StartFraction x over 1,500 EndFraction. StartFraction 10 times 30 over 20 times 30 EndFraction = StartFraction x over 1,500 EndFraction. 300 = x. He should have found the average of the number of rock songs by averaging 4 and 6 to get 5. He did not multiply the numerator and denominator by the correct number to equal 1,500. His answer will be one-half of what he got because he did not divide 10 by 2 when setting up the proportion. He can only solve the proportion by multiplying the numerator and denominator by a common multiple. He should have multiplied the numerator and denominator by 75, not 30, because 20 times 75 = 1,500
Answer:
Answer is B)
Step-by-step explanation:
Josiah's mistake is (b) He did not multiply the numerator and denominator by the correct number to equal 1,500
The proportion is given as:
Multiply both sides by 1500
Evaluate the expression on the right-hand side
Multiply 10 by 1500 on the left-hand side
Divide 15000 by 20 on the left-hand side
Rewrite the equation as:
From the question, we can see that the products are not well carried out.
Hence, Josiah's mistake is (b)
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500.
What is Fraction ?What is fraction and example?
A fraction is numerical value that is a part of a whole. It is evaluated by dividing a whole into number of parts
Types of Fractions Proper fraction,Improper fraction,Mixed fraction,Like fractions,Unlike fractions,Equivalent fractions.
The statements that are true about Josiah's solution are:
He correctly found the proportion of rock songs by setting the ratio (number of rock songs in the sample) / (total number of songs in the sample) = (number of rock songs in the MP3 player) / (total number of songs in the sample). sample MP3 player) and solving for x:
Start Fraction 10 over 20 EndFraction = Start Fraction x over 1500 End Fraction.
Initial fraction 10 times 30 over 20 times 30 final fraction = initial fraction x over 1500 final fraction.
300 = x.
He didn't hit the average of the rock songs right because the average of 4 and 6 is 5, not 300.
He did not multiply the numerator and denominator by the correct number to 1500 because he should have multiplied both by 75 instead of 30 to get:
Initial fraction 10 times 75 over 20 times 75 final fraction = initial fraction x over 1500 final fraction. He did not have to divide 10 by 2 when he determined the ratio, because the ratio is already in its simplest form. So the real arguments are:
He got the rock songs part right. He did not multiply the numerator and denominator by the correct number until 1500. He did not have to divide 10 by 2 to determine the ratio.
