Cuánto tiempo debe transcurrir para que un capital de $3,000.00 alcance un monto de $7,000.00, si la inversión se hizo con 5% de interés simple mensual?

Answers

Answer:

27 years approx

Step-by-step explanation:

Given data

Principal P= $ 3,000

Final amount A= $ 7000

Rate r= 5%

The simple interest expression is

A=P(1+rt)

substitute and solve for t

7000=3000(1+0.05t)

7000=3000+150r

7000-3000=150r

4000=150t

t= 4000/150

t= 26.66

Hence, the time is 27 years approx

5) Mario owns a plumbing business. He charges an hourly rate plus a onetime set up fee. His first job was 4 hours and he charged $450. His second job was 3 hours and he charged $675. If his set up fee is $150, how much does he charge per hour?

Answers

Answer:

Results are below.

Step-by-step explanation:

First, we need to calculate the variable income per job:

First job= 450 - 150= 300

Second job= 675 - 150= 525

Now, the hourly rate:

Hourly rate= total variable income / number of hours

First job= 300 / 4= $75

Second job= 525 / 3= $175

It is probably that the second job was 7 hours long. If not, he doesn't charge the same amount per hour

Answers

Answer:

100 meters

Step-by-step explanation:

Given that:

Distance traveled N = 50 meters

Distance traveled W = 30 meters

Distance traveled straight back south = 20 m

The distance traveled :

Distance traveled N + Distance traveled W + Distance traveled S

(50 + 30 + 20) meters

= 100 meters

You’re gonna figure out the area of each side first. I’d recommend labeling them by letter to help keep track. Do 8x5=40 then multiply 40 by 2 (because there are two sides that are 8x5) then do 3x4 which is 12 usually you would divide 12 by 2 to get the area of a triangle but in this case just leave it alone because there are two triangles. Then do 3x8 for the rectangle (24) then you’re gonna add all the sides together. So 40+40+12(or 6+6) +24...youre answer should me 116

Answer:

108 cm^2

Step-by-step explanation:

This solid is a triangular prism.

The total surface area is made up of the area of 5 faces.

The front and rear faces are called the bases and are two congruent triangles.

The other three faces are three rectangles and form the lateral area.

SA = area of bases + lateral area

The area of the bases is 2 times the area of a triangle.

The lateral area is the sum of the area of the three lateral faces, 3 rectangles, and is also the product of the perimeter of the base and the height of the prism.

SA = 2 * bh/2 + PH

where

b = base of triangular base,

h = height if triangular base,

P = perimeter of the base, and

H = height of the prism

SA = 2 * (3 cm)(4 cm)/2 + (3 cm + 4 cm + 5 cm) * (8 cm)

SA = 12 cm^2 + 96 cm^2

SA = 108 cm^2

divide by 4, 12, 21

Step-by-step explanation:

first, look at 20, and 5. How do you get there?

well, there are 2 possible ways.

20/4=5, or 20-15=5

we take it into the next pattern to get

44/4=11, and 44-15=29.

so now we know that the rule is to divide by 4

____________________________________________

36/4 = 12

84/4=21

Answer:

1. 36 / 4 = 9

2. 84 / 4 = 21

Rule: The input divided by 4. (I / 4 = O)

Step by Step explanation:

Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.

Galvin bought 3/5 as many non-fiction books as fiction books from a book fair. He read 6 non-fiction books and 13 fiction books. He then had 3/4 as many non-fiction books left to read as fiction books. How many books did Galvin buy altogether?

Answers

Answer:

Let total non-fiction books = 3x

And total fiction books = 5x

After reading 6 non-fiction books, remaining non-fiction books = 3x-6

After reading 13 fiction books, total fiction books remaining fiction books = 5x-13

(3x-6)/(5x-13) = 3/4

Solving for x, we get x = 5

So total non-fiction books = 15 and fiction books=25

So total number of books bought = 40
