Francisco has a savings account balance of 2,033.88. The interest rate on the account is 2.9% compounded monthly. If he opened the account nine years ago what was the value of his initial deposit.

Answers

Final answer:

To find the initial deposit (P) of Francisco's savings account, we can use the compound interest formula P = A / (1 + r/n)^(nt) with the given values, leading to P = 2,033.88 / (1 + 0.029/12)^(12*9) and solve for P.

Explanation:

To determine the value of Francisco's initial deposit in a savings account that has grown to $2,033.88 with an interest rate of 2.9% compounded monthly after nine years, we need to use the formula for compound interest:

P = A / (1 + r/n)^(nt)

Where:

P is the principal amount (initial deposit)A is the amount of money accumulated after n years, including interest.r is the annual interest rate (decimal)n is the number of times that interest is compounded per yeart is the time in years

Given:

A = $2,033.88r = 2.9% or 0.029n = 12 (since the interest is compounded monthly)t = 9 years

Substituting the given values into the formula, we get:

P = 2,033.88 / (1 + 0.029/12)^(12*9)

After calculating the above expression, we can find the initial deposit Francisco made into his savings account nine years ago.

Final answer:

Francisco initially deposited approximately $1,511.29 into the savings account.

Explanation:

To find out how much money Francisco initially deposited, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount ($2,033.88)

P is the principal (initial deposit)

r is the interest rate per period (2.9% or 0.029 in decimal form)

n is the number of compounding periods per year (12 for monthly compounding)

t is the number of years (9)

Plugging in the values, we can solve for P:

2,033.88 = P(1 + 0.029/12)^(12*9)

Simplifying the expression:

2,033.88 = P(1.002416667)^108

2,033.88 = P(1.343917334)

P = 2,033.88 / 1.343917334

P ≈ $1,511.29

Therefore, Francisco initially deposited approximately $1,511.29 into the savings account.

Harry rides his bike 25 Start Fraction 3 over 8 End Fraction miles. Karen rides her bike 25two-fifths miles. Who rides farther?

Answers

I believe Harry rode the farthest.

Hope this helps!

Final answer:

After converting their distances to decimals, Karen rides farther than Harry with a distance of 25.4 miles compared to Harry's 25.375 miles.

Explanation:

The question is regarding who rides farther, Harry or Karen, given their distances in different fractional forms. Harry rides his bike 25 3/8 miles, and Karen rides 25 two-fifths miles. To compare, we must convert their distances to similar fractional forms or decimals. Converting three-eighths to a decimal gives us 0.375, and converting two-fifths to a decimal yields 0.4. Therefore, Harry rides 25.375 miles, and Karen rides 25.4 miles.

Through comparison, it is clear that Karen rides farther than Harry. Karen's total distance of 25.4 miles exceeds Harry's total distance of 25.375 miles, albeit by a slight margin.

Have an average weight of 16 ounces and a standard deviation of 0.2 ounces. the weights of the sugar bags are normally distributed. what is the probability that 16 randomly selected packages will have a weight in excess of 16.075 ounces?

Answers

Standardised z score = (16.075 - 16) / 0.2  =  0.375

which gives a probability of 0.1462  for  selecting a package of weight 16.075

the probability of weight being excess of 16.075 = 0.5 - 0.1462 =  03538

Probability of picking 16 in excess of 16-075 = 0.3538^16 =  6.0273 * 10^-8

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,

Here, accoding to the PEMDAS rule, in mathematical string solution of the parenthesis is on priority. But we can see here on the left we add first 3 and 5 then the product adds to 7 and on the right, we add first 7 and 3 then the product adds to 5 gives the same result, this property of addition of number is called associative property.
As
7 + (3 + 5) = (7 + 3) + 5
7 + 8 = 10 + 5

use substitution to solve the system 5x-3y=23 2x+y=7

Answers

Because "y" is + in 2x+y=7, let's subtract 2x from both sides and end up with an expression for y:  y = 7 - 2x.  Substituting this into 5x - 3y = 23, 

5x - 3(7 - 2x) = 23.  Multiply out -3(7 - 2x):

5x - 21 + 6x = 23.  Combining 5x and 6x, 11x - 21 = 23, or 11x = 44.

Thus, x = 4.  Since y = 7 - 2x, subst. x = 4 results in the value of y:

y = 7 - 2(4) = 7 - 8 = -1.

The solution is (4,-1).

Jess spent 7x minutes on the computer. Her sister spent 5 x + 10 minutes on the computer, which was the same amount of time Jess spent. How many minutes was Jess on the computer?

Answers

7x = 5x + 10
-5x   -5x
2x = 10
x = 5

7(5) = 35 minutes

Jess spent 35 minutes on the computer

Answer: 35 minutes

Step-by-step explanation:

Given : Jess spent 7x minutes on the computer.

Her sister spent 5 x + 10 minutes on the computer, which was the same amount of time Jess spent.

Thus , we have

[tex]7x=5x+10[/tex]

Subtract 5x from both the sides , we get

[tex]2x=10[/tex]

Divide both sides by 2, we get

[tex]x=5[/tex]

Now, the time spent by Jess = 7(5)=35 minutes

Hence, Jess was 35 minutes on computer.

What is the smallest angle of rotational symmetry that maps a regular pentagon onto itself?

Enter your answer in the box.



___°

Answers

Answer:

72º

Step-by-step explanation:

In order to calculate this you have to remember that the center angle of any polygon measures 360º, so what we do is just divide those 360 by the number of angles that you will find in the polygon, the number of angles equals the number of sides, so the pentagon has 5 sides, it will also have 5 angles. So we just divide the 360/5=72

So the smallest angle of rotational symmetry that maps a regular pentagon onto itself will be 72º

the sum of two numbers is 7/8. One addend is 3/4. what is the other? A. 4/4 B. 1/8 C. 1/4 D. 2/8

Answers

7/8 - 3/4
= 7/8 - 6/8
= 1/8

answer
B. 1/8

Answer:


Step-by-step explanation:

Let the other be [tex] = x[/tex]


As the sum of the number is given as [tex] \frac {7}{8}[/tex]

And one number is [tex] \frac{3}{4}[/tex]


According to question


[tex] \frac{3}{4} +x = \frac{7}{8}[/tex]


Subtracting [tex] \frac{3}{4}[/tex] from both sides we get


[tex] \frac{3}{4} +x - \frac{3}{4} = \frac{7}{8} - \frac{3}{4}[/tex]


Taking LCM of 4 and 8 we get 8

And making

[tex] \frac{3}{4} [/tex] and [tex]\frac{7}{8}[/tex] like fraction by making denominator same.


Multiply [tex] \frac{3}{4} [/tex] by 2 in numerator and denominator and multiply [tex]\frac {7}{8}[/tex] by 1 in numerator and denominator we get


[tex]x= \frac{7}{8} - \frac{6}{8}[/tex]


[tex]x= \frac{7-6}{8}[/tex]


[tex]x =\frac{1}{8}[/tex]


Hence, the other number is [tex]\frac{1}{8}[/tex]

When performing today's experiment, your lab partner decides to add all the reagents into one beaker instead of two separate beakers. after adding everything together and waiting a significant amount of time, you see no reaction occur. what was the problem?

Answers

The problem can be an incorrect sequence of reagents added, requirement of heat or proportion of relative reactants when all the reagents simultaneously added into the beaker.

Further  explanation:

The reaction sometimes occurs in a series of elementary reaction which can be described in the reaction mechanism of that particular reaction. So when we added the incorrect sequence of reagents then the reaction may not happen as the way we want.

Some factors which can affect the reaction are as follows:

1. The ratio amount of given reagent may not be correct.

2. Some of the reactions have very slow rate of reactions and thus they required heat to increase the rate of reaction.

3. Sometimes the reagent which is important for the first step can undergo a side reaction with the reagent which should not be there otherwise.

4. That mechanism of reaction may be required light since chemoluminescence reactions depend on excitation of atoms.

5. Sometimes reactants should be mix in dark which can lose their activity in the light.
