Answer: Single deposit by Edward=$3594 to make it amount for college=$50,000 in 10 years.
Step-by-step explanation:
Here Compound amount =$50,000
Time=10 years
Rate of interest=4.3%
By the Daily compound interest formula ,we have
[tex]Amount=Principal(1+rate/365)^{365\times\ time}\\\Rightarrow\ Amount=Principal(1+4.3/365)^{365\times\ 10}\\\Rightarrow\ 50000=P(1+.011)^{3650}\\\Rightarrow\ 50000=P(1.011)^{3650}\\\Rightarrow\ 50000=P(13.911)...........(approx)\\\Rightarrow\ P=\frac{50000}{13.911}=3594......(approx)[/tex]
Therefore Principal amount deposited by Edward is $3594.
Answer:
$32,526.67
Step-by-step explanation:
Let the Principle be P
amount here A= $50,000
time n= 10 years n= 10*365=3650 days
rate of interest= 4.3% compounded daily= 4.3/365
let us use compound interest formula to calculate the principle
[tex]A= P(1+\frac{r}{100})^n[/tex]
putting all the values we get
[tex]50000=P(1+\frac{4.3}{100\times365})^10times365[/tex]
on solving we get P= $32,526.67
therefore he need to deposit $32,526.67
The tables below show running hours of three printers that produce greeting cards and the total number of greeting cards produced over three weeks.
Printer B uses $15 in ink every hour. What is the ink cost for each card coming from printer B?
A. $0.30
B. $0.50
C. $1.00
D. $1.50
ANSWER
The correct answer is A
EXPLANATION
To find the ink cost of each card coming from printer B, we need to find the total cost from printer B and the total number of cards printed by Printer B.
The total hours of all the three printers over the three weeks
[tex]=40+45+55+50+50+30+45+40+60=415[/tex]
The total hours of printer B only
[tex]=50+50+30=130[/tex]
Total number of cards produced over the three weeks
[tex]=7950+7800+9600=25350[/tex]
We can use ratio and proportion to determine the total cards produce by printer B only.
[tex]415:25350[/tex]
[tex]130:x[/tex]
If less, more divides
[tex]x=\frac{130\times 25350}{415} \approx7941[/tex]
Total cost of Printer B in 130 hours
$[tex]=130 \times 15=1950[/tex]
The ink cost
[tex]=\frac{1950}{7941}[/tex]
[tex]=0.2456[/tex]
$[tex]\approx 0.30[/tex]

i need to remember how to solve this problem
1 + 4x = -5 + 7x
1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:
1+5=7x-4x
2nd step:
3x=6
3rd step: you need to divide both sides into 3, because it is the common divisor.
x=2
To sum up:1 + 4x = -5+7x
7x - 4x = 1 + 5
3x = 6
x = 2You can try to memorize the summary. However, it is better to understand the solution as a whole.
solve for x in the equation is x^2-4x-9=29
Step 1. Move all terms to one side
[tex]x^2-4x-9-29=0[/tex]
Step 2. Simplify [tex]x^2-4x-9-29[/tex] to [tex]x^2-4x-38[/tex]
[tex]x^2-4x-38=0[/tex]
Step 3. Use the Quadratic Formula
[tex]x=\frac{4+2\sqrt{42} }{2} ,\frac{4-2\sqrt{42} }{2 }[/tex]
Step 4. Simplify solutions
[tex]x = 2 \sqrt{42,} 2-\sqrt{42}[/tex]
Let's solve your equation step-by-step.
[tex]x^{2}[/tex]−4x−9=29
Step 1: Subtract 29 from both sides.
[tex]x^{2}[/tex]−4x−9−29=29−29
[tex]x^{2}[/tex]−4x−38=0
Step 2: Use quadratic formula with a=1, b=-4, c=-38.
[tex]x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x=\frac{-(-4)+-\sqrt({-4})^{2} -4(1)(-38)}{2(1)}[/tex]
[tex]x=\frac{4-+\sqrt{168}}{2}[/tex]
Answer:
[tex]x=2+\sqrt{42}[/tex] or x = -2 [tex]\sqrt{42}[/tex]

We can write this line in y-intercept form, and then solve to convert it to standard form.
Y = mx + b
m = slope
b = y-intercept
Y = -1/4x - 2 is the slope-intercept form of the equation.
Now, we can convert this to standard form.
Add 2 to both sides.
y + 2 = -1/4x
Subtract y from both sides.
-1/4x - y = 2
Multiply all terms by -4.
x + 4y = -8 (This is your answer.)

The simple interest I on an investment of P dollars at an interest rate r for t years is given by I=Prt. Find the time it would take to earn $1400 in interest on an investment of $27,000 at a rate of 4.2%.

Aurora has a cell phone plan that charges
$65
for phone service plus
$12
for each gigabyte of data used each month. If her bill for September is
$113,
how many gigabytes of data did she use in September?
Aurora used 4 gigabytes of data in September.
Explanation:To determine how many gigabytes of data Aurora used in September, we need to subtract the fixed phone service charge from her total bill. The difference will represent the additional charges for the data usage. Let's say she used x gigabytes. The equation for her bill can be written as: 65 + 12x = 113. To solve for x, we can subtract 65 from both sides and then divide both sides by 12 to isolate x. Solving this equation, we find that x = 4. So, Aurora used 4 gigabytes of data in September.

the area of a quadrilateral is 8.4 square feet. find two decimals that give a product close to 8.4
Answer:
2.81 and 0.3 are two decimals that give a product of 8.43 which is close to 8.4
Step-by-step explanation:
let consider a decimal number 0.3
now consider another decimal number 2.81
now if we multiply these two numbers then we get 8.43 which is also a decimal number and it is close to 8.4.
Answer:
Hence the approximate values are 2.91 and 2.89
Step-by-step explanation:
The area of a quadrilateral is expressed as
A=L*B
Where L=length
B=breadth or width
I. e assuming it has two of its sides equal
Say given area is
A=L*B=8.4 square feet
Let's take the square root of the area A=2.898

What is 673.983 rounded to the nearest hundredth
I believe it would be 673.98
I hope this helps :)
673.983 rounded to the nearest hundredth is 673.98, as the third decimal digit (3) is less than 5.
To round the number 673.983 to the nearest hundredth, we need to look at the third decimal place, which is in the thousandths place. If this digit is 5 or greater, we round up. If it is less than 5, we keep the second decimal place as it is. In the case of 673.983, the third decimal digit is a 3, which is less than 5. Therefore, the number rounded to the nearest hundredth is 673.98.

Factor the expression
Factor a^2−2ab−6by+3ay
a^2−2ab+3ay−6by
=(a−2b)(a+3y)
Answer:
(a−2b)(a+3y)
the factored expression is:
a(a + y) - 2b(a + 3y)
We can factor the expression [tex]a^2-2ab-6by+ay[/tex] using a combination of grouping and factoring by difference of squares:
We can group the terms based on common factors:
[tex](a^2 + ay) - (2ab + 6by)[/tex]
In the first group, a is the common factor: a(a + y)
In the second group, 2b is the common factor: 2b(a + 3y)
Then we combine the terms
a(a + y) - 2b(a + 3y)
Therefore, the factored expression is:
a(a + y) - 2b(a + 3y)
Two investments totaling $58,500 produce an annual income of $3795. One investment yields 5% per year, while the other yields 7% per year. How much is invested at each rate?
Total investment is =$58500
Annual income produced = $3795
Rate of one investment = 5%
Rate of second investment = 7%
Let the amount invested at 5% be = x
Then, amount invested at 7% rate will be = [tex]58500-x[/tex]
The equation becomes:
5%x + 7%(58500-x) = 3795
= 0.05x + 0.07(58500-x) = 3795
0.05x + 4095 - 0.07x = 3795
0.02x = 300
x = 15000
Hence, the amount invested at 5% is = $15000
Amount invested at 7% = 58500-15000 = $43500

Write as a decimal . Tell whether the decimal terminates or repeats. 7/9
The fraction 7/9 converts to the decimal 0.77777778, which is a repeating decimal as the digit '7' repeats infinitely.
To convert the fraction 7/9 to a decimal, divide 7 by 9. So, when you divide 7 by 9, the answer you get is 0.77777778. This decimal does not terminate (come to an end after a specific number of decimal spaces), instead it repeats. Specifically, the digit '7' repeats indefinitely, so we can say its a repeating decimal.
As an example, if you consider 1/2, when you divide 1 by 2 it gives 0.5, which is a decimal that terminates. However, in our case - when we divided 7 by 9 it gave us 0.77777778 which repeats, hence it is a repeating decimal, not a terminating decimal. This is the key difference between repeating and terminating decimals.

The probability of something can be expressed as a decimal or as a percent. We know that the probability of something happening can not be below 0% or above 100%. Background information: To turn a percent into a decimal (or an integer depending on the number you are working with), you move the decimal two places to the left. For example: 56% would be 0.56 If probability has to be between 0% - 100%, between what two integers does probability have to be after you convert from a percent to an integer? *
Answer: The probability lies between 0 and 1
Step-by-step explanation:
As from the given information probability of an event lies between 0% to 100% .
To convert percent into integer or fraction we have to divide it by 100
[tex] 0\%= \frac{0}{100} = 0 [/tex]
And
[tex] 100\% = \frac{100}{100} = 1 [/tex]
From the above the probability of an event lie between integers 0 to 1.
