A man invested $10,500 for 7 years at 5 ½ % per annum simple interest.

(A) Determine the simple interest payed

(B) Calculate the amount of money he collected after the period of 7 years

Answers

Quick answer :

(A) = $4042.50 (B) = $14520.50

Solution with steps : Solution (A) :

Money invested by a man = $10,500

No.of years for which he invested his money = 7

Rate of interest = 5.5%

We know that :

[tex] \tt \: Simple \: interest = \frac{Principal × Rate × Time}{100} [/tex]

Principal = 10500

Rate = 5.5%

Time = 7 years

Simple interest the man payed :

[tex] = \tt\frac{10500 \times 55 \times 7}{10 \times 100} [/tex]

[tex] = \tt \frac{4042500}{1000} [/tex]

[tex] \color{plum}=\tt 4042.50[/tex]

Therefore, the simple interest payed by the man = $4042.50

Solution (B) :

Money invested by the man (principal) = $10,500

The simple interest he payed = $4042.50

We know that :

[tex]\tt \: amount = principal + interest[/tex]

The amount the man collected after a period of 7 years :

[tex] = \tt10500 + 4042.50[/tex]

[tex] =\tt 14520.50[/tex]

Thus, amount = $14520.50

Therefore the amount he collected after a period of 7 years = $14520.50

Dimas is playing a game that uses a number cube. The sides of the cube are labeled from 1 to 6. Dimas wants to roll a 2 or a 3. He rolls the
number cube one time,
What is the probability that he will roll a 2 or a 3?

Who ever answer FIRST I WILL GIVE YOU BRAINIEST ANSWER

Answers

Answer:

The probability that he will roll a 2 or a 3

 [tex]P((E_{1} UE_{2} ) = \frac{1}{3}[/tex]

Step-by-step explanation:

Step(i);-

Dimas is playing a game that uses a number cube.

The sides of the cube are labelled from 1 to 6

The total number of Exhaustive cases

n(S) = {1,2,3,4,5,6} = 6

Step(ii):-

Let E₁ be the event of roll a '2'

n(E₁) = 1

The probability that Dimas wants to roll a '2'

[tex]P(E_{1} ) = \frac{n(E_{1} )}{n(S)} = \frac{1}{6}[/tex]

Let E₂ be the event of roll a '3'

n(E₂) = 1

The probability that Dimas wants to roll a '3'

[tex]P(E_{2} ) = \frac{n(E_{2} )}{n(S)} = \frac{1}{6}[/tex]

But E₁ and E₂ are mutually exclusive events

P(E₁∩E₂) = 0

Step(iii):-

The probability that he will roll a 2 or a 3

we have  P((E₁UE₂) = P(E₁)+P(E₂)

                               = [tex]= \frac{1}{6} + \frac{1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]

            [tex]P((E_{1} UE_{2} ) = \frac{1}{3}[/tex]

Find the length AB ?

Answers

Answer:

AB = 54

Step-by-step explanation:

DE is a midsegment of the triangle and is half of AB , that is

2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction

4x + 26 = 13x - 37 ( subtract 13x from both sides )

- 9x + 26 = - 37 ( subtract 26 from both sides )

- 9x = - 63 ( divide both sides by - 9 )

x = 7

Thus

AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54

b. $14.99(3) + $24+ $25 = x

   $44.97 + $24 + $25 = $93.97

Step-by-step explanation:

Answer:

i) C= $14.99 k + $24

ii) $93.97

Step-by-step explanation:

Let the number of models be represented by -----------k

Let the amount spent on books to be--------$24

The equation that represent amount spent in the mall is given as;

C= $14.99 k + $24   ---------------where ;

C= the equation for the total amount spent in the mall

k = the number of plane models

ii)

Using the equation : C= $14.99 k + $24    and if k = 3 and the amount spent on the store is $25  then ;

C= $14.99 * 3 + $24 = $44.97 + $24 = $68.97

C+ 25 = $68.97 + 25 =$93.97

A ship must have 1 lifeboat for every 12 passengers, plus one lifeboat for
the crew and one backup lifeboat. Which equation shows the
relationship between the number of passengers, p, and the number of
lifeboats needed, I?

Select one

1) I= 2 + 1/2
2) I= 2p + 10
3) I= 12p
4)I=2+ p/12

Answers

Answer: Choice (4)  L = 2 + p/12

===========================================

Explanation:

p = number of passengers

L = number of lifeboats

Since we're grouping the passengers in groups of 12, this strongly implies we'll be dividing two values. Specifically we have p divided by 12 to represent the number of boats we will need just for the passengers.

For example, let's say p = 36. This means we have 36 passengers. That would mean we need p/12 = 36/12 = 3 boats for those 36 passengers. This excludes the crew and backup boat. Adding those two extra boats leads to the expression 2 + p/12 which is the total number of lifeboats needed.

In the event that p is not a multiple of 12, this leads to p/12 not being a whole number. We could have say p = 50 passengers which means p/12 = 50/12 = 4.167 approximately. We will not round this to 4 because then we'll have passengers without a lifeboat.

We must round 4.167 up to the nearest whole number to get 5. The first four boats take care of 4*12 = 48 passengers, while that 5th boat handles the remaining 50-48 = 2 people. Since 2 people in a boat seems like a really low count, the crew could likely spread the people out such that say 10 people would be in each boat (since 50/10 = 5).

So in short, the result of p/12 is rounded up to the nearest whole number.

Michael has 567 pennies, Jorge has 464 pennies, and Jamie has 661 pennies. If the pennies are shared equally by the 3 boys and 33 of their classmates, how much money will each classmate receive? ( please show me the steps)

Answers

Answer:

Everybody, including the three boys, will get 47 pennies.

Step-by-step explanation:

First, you add the number of pennies each of the boys has, 567+464+661 = 1,692. Then you take the 1,692 and divide it by 36 to get 47. You divide by 36 because the pennies are getting shared by the 3 boys and 33 classmates, which comes out to be 36 classmates in total.

x is part of a 30 60 90 triangle.

next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.

Answers

Answer:

the slope is -3/2, and the y-intercept is 5/2.

Step-by-step explanation:

3x + 2y = 5

putting it into a y = mx+b form,

2y = -3x + 5

y = -3/2x + 5/2

the slope is -3/2, and the y-intercept is 5/2.

Answer:

y-intercept= 2.5

x- intercept= 1.666666666..... or 5/3

Step-by-step explanation:

1. Move variable to other side.

3x+2y= 5

-3x        -3x

2y= -3x+5

2. Divide each side by 2.

-3/ 2 = -1.5

5/2 = 2.5

y= 1.5x+2.5

y= mx+b

b= y-intercept

b=2.5

3. Replace y with 0 to solve for x intercept.

3x+ 2 x 0 = 5

3x= 5

5/3 = x

Steve has 1 1/2 cups of flour. One of his recipes requires 1/8 cup of flour. What is the maximum number of times (batches) Steve can complete the recipe?

Answers

Answer:

12 batches

Step-by-step explanation:

Total cups of flour = 1 1/2

Flour used per batch = 1/8 cups

What is the maximum number of times (batches) Steve can complete the recipe?

Maximum batches Steve can make = Total cups of flour / Flour used per batch

= 1 1/2 ÷ 1/8

= 3/2 ÷ 1/8

= 3/2 × 8/1

= (3*8) / (2*1)

= 24 / 2

= 12 batches

Maximum batches Steve can make = 12 batches
