So, you want to calculate the interest on $300 at 5% interest per year after 7 years.

The formula we'll use for this problem is:

Where:

To find the simple interest, we multiply 300 x 0.05 x 7 to get that:

                                         The interest is: $105.00

Answer:

The correct answer is last option

$105.00

Step-by-step explanation:

Points to remember

Simple interest

I = PNR/100

Where P - Principle amount

N - Number of years and

R - Rate of interest

To find the simple interest

Here P = $300, R = 5% and N = 7 years

I = PNR/100

 = (300 * 5 * 7)/100

 = 3 * 5 * 7

 = 105

Therefore simple interest after 7 years = $105

The correct answer is last option

Answer:

A) X=-2

Step-by-step explanation:

by multiplying the first term by -3 then -6X-3y=-3

                                                            and  2X+3y=11

then by adding = -4X=8

then X=8/-4=-2

The value for x in the given system of equations is found by using the method of elimination, resulting in x = -2. The value of y was found first, namely y = 5, and was then substituted into the first equation to find x.

The system of equations given is:

To find the value of x, we can use the method of elimination or substitution. Let’s use elimination. First, subtract the first equation from the second.

That gives us: 2x + 3y - (2x + y) = 11 - 1

Which simplifies to: 2y = 10

Then divide both sides by 2: y = 5

Now substitute y = 5 into the first equation: 2x + 5 = 1, which simplifies to 2x = -4, and lastly x = -2.

So the solution for x in the system is x = -2 (option a.).

Step-by-step explanation:

Wire is 4 1/2 feet, or 4.5 feet.

Each smaller wire needs to be 1 1/4 feet, or 1.25 feet.

Answer:

A = $5,417.42 (balance of the account)

I = $2,617.42

Answer:

The balance in the account after 12 years is $5417.42

Step-by-step explanation:

* Lets talk about the compound continuous interest

- Compound continuous interest can be calculated using the formula:

 A = P e^rt

• A = the future value of the investment, including interest

• P = the principal investment amount (the initial amount)

• r = the interest rate

• t = the time the money is invested for

- The formula gives you the future value of an investment,

  which is compound continuous interest plus the

  principal.

- If you want to calculate the compound interest only, you need

 to deduct the principal from the result.

- So, your formula is:

 Compounded interest only = Pe^(rt)  - P

* Now lets solve the problem

∵ P = $ 2800

∵ r = 5.5/100 = 0.055

∵ t = 12

∴ A = 2800 e^(0.055 × 12) = $5417.42

* The balance in the account after 12 years is $5417.42

Answer: 3,600,000 cm³

Step-by-step explanation: First you have to convert all the units into centimeters,

2 meters = 200 centimeters

1.5 meters = 150 centimeters

To find the volume of a rectangular prism you multiply all the sides.

120 * 200 * 150 = 3,600,000

The answer is 3,600,000 cubic centimeters.

The volume of a rectangular prism with the given dimensions is 3.6 cubic meters.

The dimensions of a rectangular prism are 120 centimetres(1.2 meters) by 2 meters by 1.5 meters.

The formula to find the volume of a rectangular prism is l×b×h.

Now, volume=1.2×2×1.5=3.6 cubic meters.

Therefore, the volume of a rectangular prism is 3.6 cubic meters.

The would both be correct in it's own way depending on how the teacher is teaching.

Both Joel and Sara are correct. Their expressions represent the combined earnings accurately, considering hourly wage and bonus.

To determine who is correct, let's first break down the earnings for each person:

1. Joel:

  - Hourly wage: $9.75

  - Bonus: $18

  Joel's total earnings can be calculated using the formula provided: [tex]\(9.75j + 18\)[/tex], where [tex]\(j\)[/tex] represents the number of hours Joel worked.

2. Sara:

  - Hourly wage: $9.75

  Sara's total earnings can be calculated using the formula provided: [tex]\(9.75(j + S)\)[/tex], where [tex]\(S\)[/tex] represents the number of hours Sara worked.

Now, let's expand both expressions and see which one correctly represents the combined earnings of Joel and Sara.

Joel's expression: [tex]\(9.75j + 18 + 9.75S\)[/tex]

Sara's expression: [tex]\(9.75j + 9.75S + 18\)[/tex]

Comparing the two expressions, we see that both expressions have the same terms: [tex]\(9.75j\)[/tex], [tex]\(9.75S\)[/tex], and [tex]\(18\)[/tex]. The order of terms is different, but mathematically it doesn't matter since addition is commutative.

So, both Joel and Sara are correct. They just wrote their expressions in a different order, but the mathematical result is the same. They both correctly accounted for their hourly wage and the bonus.

Answer:

57°

Step-by-step explanation:

ALL angles in a triangle add up to 180°

SO, if we know the sum of two angles which is 123° (why: 33+90=123), all we have to do is subtract this number from 180 to get the measure of the 3rd angle. Which in this case is 57°

The measure of angle B will be 57° for the given triangle.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right angle triangle, equilateral triangle, and much more.

The sum of all three interior angles of any triangle is 180°.

So,

A + B + C = 180°

Given,

A = 33°  and C = 90°

33°  + B + 90°  = 180°

B = 180 - (90 + 33)

B = 180°  - 123°  

B = 57°

Hence, The measure of angle B will be 57° for the given triangle.

4. [tex]6x-7+7=12+7[/tex] - Simplification

7. [tex]x=\frac{19}{6}[/tex]

To solve the problem, we need to start with the result of the second step:

[tex]6x-7=12[/tex]

So,

For the step 3:

Then, for the 3rd step, we have to apply the addition property of equality.

The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.

Then, applying the property, we have:

[tex]6x-7=12[/tex]

Adding 7 to both sides, we have:

[tex]6x-7+7=12+7[/tex]

For the step 4:

Now, for the 4th step, we have to simplify the expression:

[tex]6x-7+7=12+7[/tex]

Then, simplifying, we have:

[tex]6x=19[/tex]

For the step 7:

Simplificating, we divide each side of the equality by 6:

Answer:

option B

Step-by-step explanation:

Given in the question an equation y = (x+3)² + (x+4)²

Step 1

Expand this equation

y = (x+3)² + (x+4)²

y = (x²+9+6x) + (x²+16+8x)

y = 2x² + 14x + 25

Step 2

Find the minimum point of the parabola equation,  y = 2x² + 14x + 25

y = ax² + bx +c

x = -b/2a

  = -14/2(2)

  = -14/4

 = -7/2

Step 3

Find the vertex point by plugging value of x in the equation

y = 2(-7/2)² + 14(-7/2) + 25

  = 49/2 - 49 + 25

  = 1/2

vertex (h,k)

vertex (-7/2 , 1/2)

Step 4

vertex form

y = a(x - h)²+ k

y = 2(x + 7/2)² + 1/2

Answer:

14 are red

Step-by-step explanation:

Let's identify the 2 types of transactions Juan machines do:

w : changes 1 white token into 4 red tokens (gain: 3 tokens overall)

r : changes 1 red token into 3 white tokens (gain: 2 tokens overall)

We know that Juan does 11 trades, so we can say:

w + r = 11

Overall, Juan started with 4 tokens and ends with 31... so, gain of 27 tokens.

We can model this as:

3w + 2r = 27

(3w because each w transaction, he gains 3 tokens, 2r because every r transaction, he gains 2 tokens).

From first equation we get r = 11 - w, which we place in the second equation:

3w + 2 (11 - w) = 27

3w + 22 - 2w = 27

w = 5, so r = 6 (from first equation).

Now, we know Juan did 5 w transactions and 6 r transactions.  But how many token of each color does he have?

Start: 4W (4 White chips)

He does 4 w transactions, he now has 16R tokens

He does 6 r transactions, he now has 10 (16-6) R tokens, plus 18 W tokens

He does another w transaction, he now has 14 R (10 + 4), plus 17 W(18-1) tokens

He did 11 transactions, and he has 31 tokens at the end, out of which 14 are red.
