$225 grows 3.2% in an account. How much money is in the account after the growth? Express your answer to two decimal places.
Answer:
To find out how much money is in the account after the growth, we can use the formula:
FV = PV(1+r)
Where FV is the future value of the account, PV is the present value of the account, and r is the rate of growth expressed as a decimal.
In this case,
PV = $225
r = 3.2% = 0.032 (as a decimal)
By substituting the values in the formula:
FV = PV(1+r)
FV = $225 * (1 + 0.032)
FV = $225 * 1.032
FV ≈ $232.7 (rounded to two decimal places)
Therefore, the account has $232.7 after the growth of 3.2%.
Answer: $232.20
Step-by-step explanation:
3.2%=0.032
225x0.032=7.2
225+7.2=232.2

Julia keeps track of her driving so that she can take a tax deduction. Julia drove 120 miles last month, in comparison to 78 miles this month. By what percent has her monthly driving decreased?_____%
Answer:
Step-by-step explanation:
The percent decrease in Julia's monthly driving would be 35.9%. This is calculated by taking the difference between the two months (120 - 78 = 42) and dividing it by the initial amount (120) and then multiplying the result by 100. (42/120)*100 = 35.9%.
Her monthly driving decreased by 35%
Step-by-step explanation:
120m - 78m = 42miles 42/120 × 100 = 35 %Can someone help with this one? Due tomorrow.

Answer:
Step-by-step explanation:
consider the equation "-7=1/2(z+12)"
[tex]-7=\dfrac{1}{2} (z+12)[/tex]
Distribute:
[tex]-7=(\dfrac{1}{2} )(z)+(\dfrac{1}{2} )(12)[/tex]
[tex]\dfrac{1}{2} z+6=-7[/tex]
Subtract 6 from both sides:
[tex]\dfrac{1}{2} z+6-6=-7-6[/tex]
[tex]\dfrac{1}{2} z=-13[/tex]
Multiply both sides by 2:
[tex]2\times(\dfrac{1}{2} z)=2\times(-13)[/tex]
[tex]\fbox{z = -26}[/tex]
Answer:
-26
Step-by-step explanation:
1. distribute
1/2z+6=-7
-7-6=-13
1/2z=-13
-13 / 1/2 = -13 x 2/1 = -26
z = -26
double check:
1/2(-26+12)

The table shows the numbers of bags of different flavors of potato
chips on a store shelf. A customer will randomly select one bag of
potato chips from the shelf.
Potato Chips
Flavor:
Plain = 12
Jalapeño = 18
Ranch = 8
Cheese = 20
Which statement about the flavor of the potato chips chosen is best
supported by the information in the table?
F) The flavor is least likely to be plain.
G) The flavor is twice as likely to be jalapeño as ranch.
H) The flavor is equally likely to be plain, jalapeño, ranch, or cheese.
J) The flavor is more than twice as likely to be cheese as it is to be ranch.
Answer:
Step-by-step explanation:
we can start with process of elimanation.
f) wrong. this is because 12 is the second smallest number out of the four with ranch being the smallest with 8.
g) wrong. this is because 8x2=16, which means its not twice as likely it would end up. being more than twice as likely.
h) wrong. all of these numbers are different, so are smaller and bigger than others, so the rate of probability is going to be different for each chip type.
j) right. this is because if we do 8x2=16, that is still smaller than 20 so it is MORE than 2x as likely since 20 is a greater number than 16.
CORRECT ANSWER: J.
hope this helped!!
The statement which best supported is J) The flavor is more than twice as likely to be cheese as it is to be ranch.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Total number of chips = 12 + 18 + 8 + 20 = 58
Probability of finding Plain chips = 12/58 = 0.2069
Probability of finding Jalapeno chips = 18/58 = 0.3103
Probability of finding Ranch chips = 8/58 = 0.1379
Probability of finding Cheese chips = 20/58 = 0.3448
The flavor is least likely to be Ranch, not plain.
Twice the probability of Ranch = 0.2759
Hence the correct option is The flavor is more than twice as likely to be cheese as it is to be ranch.

Mr. Baxter has 250 students. Of the 250 students, 130 are girls. What is the ratio of the boys to the total number of students in Mr. Baxter's class
Answer:
It is 12boys:13girls
Step-by-step explanation:
The total is 250 out of which 130 are girls. So it is 250-130 which is 120boys. Now to find the ratio it is 120:130 which in its simplest form is 12 boys:13 girls.
Maria claims that any fraction located between 1/5 and 1/7 on a number line must have a denominator of 6.
Enter a fraction that shows Maria's claim is incorrect.
Step-by-step explanation:
I want to know about exponent and surds
Explanation:
Let's rewrite each given fraction with a common denominator of 5*7 = 35.
1/5 = (1/5)*(7/7) = 7/35
1/7 = (1/7)*(5/5) = 5/35
Then we can see that 6/35 is between 5/35 and 7/35, since 6 is between 5 and 7.
Put another way: 5/35 < 6/35 < 7/35 since 5 < 6 < 7
This then means 1/7 < 6/35 < 1/5
Therefore, Maria's claim is incorrect.
I just need "Will this be true for any positive value of x?Justify your response" I will put you brainiest!
Answer: This situation cannot be true for any positive value of x. The valid range would be 0 < x < 4. If the x is less than 4, the perimeter of triangle 1 is always greater than triangle 2.
Explanation: We need to add up the lengths of the sides for obtaining the perimeters first.
Triangle 1: 5x + 57
Triangle 2: 11x + 33
Then, we need to build up an inequality for the case which the perimeter of triangle 1 is always greater than triangle 2.
This means => 5x + 57 > 11x + 33
If we write "x" values on one side:
24 > 6x
Then dividing by 6 for both sides:
4 > x
This means that a positive value of x should be less than 4 for this particular situation.

Answer:
A) solution 2 is more acidic than solution 1
Step-by-step explanation:
A chemist prepares two acid solutions:
Solution 1: 3 parts sulfuric acid to 7 parts water
Ratio of sulphur to water: 3/7 (3:7)
Solution 2: 4 parts sulfuric acid to 9 parts water
Ratio of sulphur to water: 4/9 (4:9)
___________________________________________________
Part A: (using ratios to determine which solution is more acidic)
First we make same denominator, since the denominators are 9 and 7, we have to find the lcm (lowest common multiple) they both have with is 63. To do that, we must multiply the denominators with either 7 or 9.
Solution 1: Numerator (3) multiplied by 9 and then denominator (7) multiplied by 9. This makes out fraction/ratio 27/63
Solution 2: Numerator (4) multiplied by 7 and then denominator (9) multiplied by 7. This makes out fraction/ratio 28/63
Since 28/63 (or just 28) is a larger quantity than 27/63 (or just 27) this means solution 2 is more acidic than solution 1.
Mathematical Line (Not sure what you would call this lol): 28 > 27
Part B: (Let 'y' amount of sulfuric acid mix with 'x' amount of water)
Equation of solution 1: y = 3/7x
Equation of solution 2: y = 4/9x
Please find attachment for graph.
Part C: Don't have a graph, sorry! (part a. method is more preferred to find more acidic because it gives the actual acidic amount.)
