You invest $5000 in an account at 5.5% per year simple interest. How much will you have in the account at the beginning of the 6th year?

Answers

Answer:

The amount in the account in the beginning of the 6th year is $6375 .

Step-by-step explanation:

Formula

[tex]Simple\ interest = \frac{Principle\times Rate\ times Time}{100}[/tex]

As given

You invest $5000 in an account at 5.5% per year simple interest.

Principle = $ 5000

Rate = 5.5 %

Time = 5 years

(As calculate amount in the account for beginning of 6th year.)

Putting all the values in the formula

[tex]Simple\ interest = \frac{5000\times 5.5\times 5}{100}[/tex]

[tex]Simple\ interest = 50\times 5.5\times 5[/tex]

Simple interest = $ 1375

Amount = Principle + Simple interest

Putting values in the above formula

Amount = $5000 + $1375

Amount = $ 6375

Therefore the amount in the account in the beginning of the 6th year is $ 6375 .

Which fraction is a multiple of 1/9

Answers

3/27
Hope this help you

Final answer:

A fraction is a multiple of 1/9 if it can be written as a whole number multiplied by 1/9. For example, 2/9 is a multiple of 1/9 because it is obtained by multiplying 1/9 by 2.

Explanation:

To find which fraction is a multiple of 1/9, one can multiply 1/9 by any whole number. For instance, if we multiply 1/9 by the number 2, we obtain 2/9. This resulting fraction is indeed a multiple of 1/9 since we have simply doubled the numerator while keeping the denominator the same. When we multiply both the numerator and the denominator by the same factor, we are maintaining the proportion, hence a multiple of 1/9.

So the question at hand is about identifying a fraction that, when simplified, would be a whole number times 1/9. Such fractions can be formed by multiplying the numerator (1) of 1/9 by any non-zero integer and keeping the denominator (9) constant. For example, 3/9 is a multiple of 1/9 as 3 is a whole number and 3/9 can be simplified to 1/3, which is 3 times 1/9.

Find the value of X in the triangle.

Please explain. Thanks.

Answers

29°

triangles can only have 180°

This is a right triangle, so one angle is 90°, leaving us with 90° left

90°-61°= 29°

X=29
You have a right angle, they're always 90 degrees, plus 61 degrees = 151, next you subtract 151 from 180 = 29 degrees.

Answers

The formula in computing the simple interest of a savings account is:

I = Prt

Where I = interest earned

P = principal amount deposited

r = rate

t = time in years

You are asked to find the total amount of interest earned at the end of 5 years. Substituting the amounts to the formula:

I = $500 (4%) (5)

I = $100

Therefore, the total amount of interest earned at the end of 5 years is $100.

Anna plants peas in 3/8 of her garden and herbs in 1/8 of it. she divides the rest of the garden into 6 sections. what fraction of the original garden is in each section?

Answers

To find this answer you will first subtract the two fractions from the original size of one whole garden. After that take the remaining amount and break it into six sections. This answer would represent the fraction of the original garden that is in each section. Here are the steps:
1. Add the two fractions together to get 4/8 or 1/2. This means that half of it is left.

2. Take the 1/2 that remains and divide it by 6 (1/2 divided by 6 = 1/2 x 1/6). The answer is 1/12.

3. 1/12 of the original garden is in each section.

Evaluate sin[2 arccos( -8/17 )].

Answers

Recall that [tex]\sin2x=2\sin x\cos x[/tex], so that

[tex]\sin\left(2\arccos\left(-\dfrac8{17}\right)\right)=2\sin\left(\arccos\left(-\dfrac8{17}\right)\right)\cos\left(\arccos\left(-\dfrac8{17}\right)\right)[/tex]

Dealing with the cosine terms is simple, since [tex]\cos(\arccos x)=x[/tex] (so long as [tex]0\le \arccos x\le\pi[/tex], which is true here). So

[tex]\cos\left(\arccos\left(-\dfrac8{17}\right)\right)=-\dfrac8{17}[/tex]

To find the sine, we can make a substitution of [tex]\theta=\arccos\left(-\dfrac8{17}\right)[/tex]. In other words, we suppose that [tex]\theta[/tex] is some angle that satisfies [tex]\cos\theta=-\dfrac8{17}[/tex].

If this is the case, then we have

[tex]\sin^2\theta=1-\cos^2\theta=\dfrac{225}{289}\implies\sin\theta=\pm\sqrt{\dfrac{225}{289}}=\pm\dfrac{15}{17}[/tex]

But which value do we choose? We know that [tex]\cos\theta[/tex] is negative, which means [tex]\theta[/tex] must be between [tex]\dfrac\pi2[/tex] and [tex]\pi[/tex]. The sine of any angle [tex]\theta[/tex] in this interval will always be positive, so in fact

[tex]\sin\theta=\sin\left(\arccos\left(-\dfrac8{17}\right)\right)=\dfrac{15}{17}[/tex]

Putting everything together, we get

How many minutes pass from 4:21 to 4:59

Answers

Answer:

37 minutes

Step-by-step explanation:

Final answer:

To calculate the time elapsed from 4:21 to 4:59, perform a subtraction of the two times which results in a difference of 38 minutes.

Explanation:

To find out how many minutes have passed from 4:21 to 4:59, you have to perform a simple subtraction operation. Subtract the earlier time from the later time. In this case, it's 4:59 minus 4:21.

Step 1: Note the minutes in each time. We have 59 minutes at 4:59 and 21 minutes at 4:21.

Step 2: Subtract the earlier minute count from the later one. So, 59 minus 21 equals 38.

Therefore, from 4:21 to 4:59, 38 minutes have passed.

Jessie set up a lemonade stand for three days. On Saturday, she sold 10 2/3 gallons of lemonade. On Saturday, she sold 3 1/3 gallons more than she sold Saturday. On Monday, she sold 2 2/3 gallons Less than she sold on Saturday. How many gallons of lemonade did Jessie sell on Monday?

Answers

Lemonade sold on Saturday = 10 2/3 Gal
Lemonade sold on Monday = Lemonade sold on Sunday - 2 2/3
= 10 2/3 - 2 2/3
= 32/3 - 8/3
= 8

So, Jessie sold 8 Gal of Lemonade on Monday.

The number of gallons of lemonade did Jessie sell on Monday was 14/3.

Organizing the information given in the statement, we have that:

On Saturday, she sold 10 2/3 gallons of lemonadeOn Sunday, she sold 3 1/3 gallons more than she sold SaturdayOn Monday, she sold 2 2/3 gallons Less than she sold on sunday

Calculating how many gallons were sold, we have:

Share 150 pounds in the ratio 4:1

Answers

Final answer:

To share 150 pounds in the ratio of 4:1, divide the total by the sum of the parts of the ratio to find the value of one part, then multiply to find each share. The shares are 120 pounds and 30 pounds.

Explanation:

To share 150 pounds in the ratio of 4:1, you first need to add up the parts of the ratio (4 + 1 = 5 parts). Then, divide the total amount by the number of parts to find out how much one part is worth. In this case, 150 pounds ÷ 5 parts = 30 pounds per part. The ratio dictates that one share should have 4 parts and the other should have 1 part. Therefore, multiply 30 pounds by 4 to find the first share: 30 pounds × 4 = 120 pounds. The second share is just one part: 30 pounds × 1 = 30 pounds.

To summarize, the first person would receive 120 pounds and the second person would receive 30 pounds. This completes the sharing of 150 pounds in a 4:1 ratio.

Unit conversion is not directly relevant to this problem, but if you need to convert units, remember to use the proper conversion factors and set up the appropriate proportion.

Final answer:

To share 150 pounds in the ratio 4:1, divide the weight into 5 parts and allocate 4 parts for one ratio and 1 part for the other ratio. Each part would be equal to 30 pounds.

Explanation:

To share 150 pounds in the ratio 4:1, you can divide the total weight into 4 parts for one ratio and 1 part for the other ratio. To find the weight for each part, divide 150 by the sum of the ratio, which is 5 (4+1). Each part would be equal to 150/5 = 30 pounds. Therefore, in the ratio 4:1, the first part would be 4 parts x 30 pounds = 120 pounds, and the second part would be 1 part x 30 pounds = 30 pounds.
