Answer:

i) $500 at 5% simple interest for two years. Interest = 550 - 500 = $50

ii) $500 at 3% compounded monthly for 2 years.

    Interest = 530.88 - 500 = $30.88

Step-by-step explanation:

i) $500 at 5% simple interest for two years.

   Initial amount, P = $ 500

   Rate of interest, r = 0.05

   Time in years, t = 2

  Therefore Final amount A = P(1 + rt) = 500(1 + (0.05 [tex]\times[/tex] 2) ) = $550

   Therefore Interest = 550 - 500 = $50

ii) $500 at 3% compounded monthly for 2 years

    Initial or Principal Amount, P  = $500

    Rate of interest, r =0.03

    number of conversions, m = 12

     Time in years, t = 3

  Therefore final amount,  [tex]A = P(1 + \frac{r}{m}) ^{mt} = 500( 1 + \frac{0.03}{12} )^{(12\times2)} = 500( 1 + \frac{0.03}{12} )^{24}[/tex] = $530.88

Therefore Interest = 530.88 - 500 = $30.88

Answer:

0

Step-by-step explanation:

I would say this because n is most likely equal to 0 so 6 times 0 is 0

If 5n = 0, then 6n = 0.

If 5n = 0, then substituting 0 for 5n gives 6n = 6(0) = 0. Therefore, 6n is equal to 0.

The tax rate is 6 %

Solution:

Given that, A man purchased a magazine at the airport for $ 2.89

The tax on the purchase was $ 0.18

To find: tax rate in percentage

From given,

Magazine price = 2.89

Tax amount = 0.18

Therefore, tax percent is given as:

Let "x" be the tax percent

x % of magazine price = tax amount

x % of 2.89 = 0.18

Solve the equation for "x"

[tex]x \% \times 2.89 = 0.18\\\\\frac{x}{100} \times 2.89 = 0.18\\\\2.89x = 0.18 \times 100\\\\2.89x = 18\\\\Divide\ both\ sides\ by\ 2.89\\\\x = 6.22 \approx 6[/tex]

Thus tax rate is 6 %

The step-by-step solution shows that the number close to 289 when multiplied by 8 is approximately 36.125. Multiplying 36 by 8 gives 288, which is close to 289.

To find the number which, when multiplied by 8, gives a value close to 289, we can set up the equation:

8x ≈ 289

To solve for x, we divide 289 by 8:

Performing the division:

So, 8 times approximately 36.125 equals close to 289. Therefore, the nearest whole number would be 36, since 8 * 36 = 288, which is close to 289.

The step-by-step solution shows that the number close to 289 when multiplied by 8 is approximately 36.125. Multiplying 36 by 8 gives 288, which is close to 289.

combine you like terms

4p and -p = 3p

3p+2=0

subtracts 2 from itself and 0

3p=-2

divide 3p from itself and -2

p=-2/3

Final answer: [tex]4p^2[/tex]- p = 0, factor out the greatest common factor (p) and solve for p by setting each factor equal to zero. The solutions are p = 0 and p = 1/4.

Explanation:

To solve the quadratic equation [tex]4p^2[/tex] - p = 0, we can use the factoring method or the quadratic formula. In this case, factoring is convenient:

Therefore, the solutions to the equation are p = 0 and p = 1/4.

Answer:

x=6*sqrt(5)

Step-by-step explanation:

We use Pythagoras' theorem:

x^2 =6^2+(24/2)^2

x^2 =6^2+12^2

x^2 =36+144

x^2=180

x=sqrt(180)

x=sqrt(9*4*5)

x=3*2*sqrt(5)

x=6*sqrt(5)

The money with Geno originally is not more than $ 475

Solution:

Given that,

Geno withdrew $50 from his savings account

If he now has no more than $425 in his savings account

To find: Money had by geno originally

Let "x" be the money with Geno originally

From given,

He withdrew $ 50 from "x"

Then we can say,

[tex]x - 50\leq 425[/tex]

Here, we used "less than or equal " because he now has no more than $425 in his savings account

Solve the inequality

Add 50 to both sides

[tex]x - 50 + 50 \leq 425 + 50\\\\x\leq 425 + 50\\\\x\leq 475[/tex]

Thus the money with Geno originally is not more than $ 475

Answer:

The lowest height at which the two stacks will be the same height is 24 inches.

Step-by-step explanation:

For answering this problem, we have to find out the lowest common multiple of 6 and 8, listing its prime factors, this way:

6 = 3 * 2

8 = 2 * 2 * 2

Now, we multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Therefore, we have:

2 : 3 times as prime factor of 8

3: 1 time as prime factor of 6

The lowest common multiple is:

2 * 2 * 2 * 3 = 24

The lowest height at which the two stacks will be the same height is 24 inches.

The lowest height at which these stacks will be the same is 24 inches.

To find the lowest height at which an 8-inch box stack and a 6-inch box stack will be the same, we need to determine the least common multiple (LCM) of their heights. The method involves finding the smallest common multiple between the two heights.

    2.Identify the smallest common multiple:

Therefore, the lowest height at which the two stacks of boxes will be the same is 24 inches.

Luis would have read 696 books if he reaches his reading goal for the next year.

Step-by-step explanation:

we know that

If Luis reaches his goal, to find out how many books Luis will have read, add up the number of books he read last year plus the number of books he read this year plus the number of books he wants to read next year

so

[tex]187+224+285=696\ books[/tex]

Final answer:

When Luis reaches his goal next year, he will have read a total of 696 books.

Explanation:

Luis's book reading progression:

Question:

Kiyo and Steven are tiling the floors in an office building. Kiyo tiled [tex]\frac{3}{6}[/tex] of the floor in  one office, and Steven tiled [tex]\frac{5}{12}[/tex] of the floor  in another office.  Write to explain how to use a benchmark  fraction to determine who tiled a greater  portion of a floor.

Answer:

Kiyo tiled a greater portion of a floor

Solution:

Kiyo tiled in one office = [tex]\frac{3}{6}[/tex]

Steven tiled in another office = [tex]\frac{5}{12}[/tex]

Bench mark fraction means comparing fractions with common fraction or number. Most probably we use [tex]\frac{1}{2}[/tex] as the common fraction.

Compare [tex]\frac{3}{6}[/tex] and [tex]\frac{5}{12}[/tex] using [tex]\frac{1}{2}[/tex]:

[tex]\frac{3}{6}[/tex] is equal to the fraction [tex]\frac{1}{2}[/tex].

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

[tex]$\frac{5}{12}<\frac{1}{2}[/tex]

[tex]$\Rightarrow\frac{5}{12}<\frac{3}{6}[/tex]

Steven tiled the floor < Kiyo tiled the floor.

Hence Kiyo tiled a greater portion of a floor.

Kiyo tiled a greater portion of the floor.

To determine who tiled a greater portion of the floor, we can use a benchmark fraction. A common benchmark fraction is 1/2. Let's compare each person's portion to this benchmark:

Kiyo tiled 3/6 of the floor. Simplifying this fraction, we get 1/2.

Steven tiled 5/12 of the floor. To compare this to 1/2, we check if 5/12 is more than or less than 6/12 (which is 1/2).

Since 5/12 is less than 6/12, Steven tiled less than half, and Kiyo tiled exactly half.

Therefore, Kiyo tiled a greater portion of the floor.

Complete question: Kiyo and Steven are tiling the floors in an office building. Kiyo tiled 3/6 of the floor in one office, and Steven tiled 5/12 of the floor in another office. Write to explain how to use a benchmark fraction to determine who tiled a greater portion of a floor. You can compare hese fractions because the floors in each office are the same size. ∩ C

Answer:

Therefore,

The steering wheel’s diameter is 14 inches.

Step-by-step explanation:

Given:

Circumference of Steering Wheel ,

C = 43.96 inches

pi = 3.14

To Find:

Diameter = d = ?

Solution:

The Formula for Circumference is given as,

[tex]Circumference = \pi\times Diameter[/tex]

Substituting the values we get

[tex]C=\pi\times d\\43.96=3.14\times d\\d=\dfrac{43.96}{3.14}=14\ inches[/tex]

Therefore,

The steering wheel’s diameter is 14 inches.

When you have the circumference of a circle and need to find the diameter, you can use the formula Diameter = Circumference / π. Using this formula, Joey's steering wheel, with a circumference of 43.96 inches, would have a diameter of approximately 14 inches.

To find the diameter of a circle when you know the circumference, use the formula Circumference = π * Diameter. Circumference is the given 43.96 inches.

So, you can rearrange the formula to find the diameter: Diameter = Circumference / π.

Substituting the given values, we have Diameter = 43.96 inches / 3.14. This gives approximately 14 inches as the diameter of the steering wheel in Joey's car.

                             = 4 - 12x

The question is:

Which expression is equivalent to -6 (-[tex]\frac{2}{3}[/tex] + 2x)?

The ordered pair (a, b) satisfies the inequality y > x + 10 if the point lies above the line y = x + 10.

To determine which statement is true for the inequality y > x + 10, we need to understand the graph of this inequality. The graph of y > x + 10 represents all the points above the line y = x + 10. Since the inequality does not have an equals sign, the line itself is not included in the solution.

In this case, the line y = x + 10 has a slope of 1 and a y-intercept of 10. By comparing the equation of the line to the inequality, we can see that the line separates the coordinate plane into two regions: the region above the line and the region below the line.

The ordered pair (a, b) will satisfy the inequality y > x + 10 if the point lies above the line y = x + 10. Therefore, the correct statement is that The ordered pair (a, b) lies above the line y = x + 10.

The true statement based on the inequality  b > a + 3  is:

C.  b  is greater than  a .

Given that the ordered pair a, b satisfies the inequality y > x + 3, we can substitute a for x and b for y. This means that:

[ b > a + 3 ]

We need to determine which statement is true based on this inequality. Let's evaluate each option:

A. If you add 3 to  b , it will equal  a

This implies:

[ b + 3 = a ]

From  b > a + 3 , it is clear that  b  is greater than  a + 3 , so adding 3 to  b  will not equal  a . Thus, this statement is false.

B.  a  is greater than  b

This implies:

[ a > b ]

From  b > a + 3 , it is clear that  b  is greater than  a  plus an additional 3, so  a  is not greater than  b . Thus, this statement is false.

C.  b  is greater than  a

This implies:

[ b > a ]

From  b > a + 3 , it is clear that  b  is indeed greater than  a  by more than 3. Thus, this statement is true.

D. If you subtract 3 from  b , it will equal  a

This implies:

[ b - 3 = a ]

From  b > a + 3 , subtracting 3 from  b  will still be greater than  a , so this equation will not hold. Thus, this statement is false.

Conclusion:

The true statement based on the inequality  b > a + 3  is:

C.  b  is greater than  a .

Complete question

The ordered pair (a,b) satisfies the inequality y>x+3. Which statement is true?

__ / __

38 / __

38 / x

The algebraic expression for the phrase 'the quotient of 38 and x' is

38 ÷ x.

The word phrase "the quotient of 38 and x" can be translated into an algebraic expression as follows:

"The quotient" refers to division, so we will use the division symbol (÷).

"38" represents the numerator of the quotient, the number that is being divided.

"x" represents the denominator of the quotient, the number by which we are dividing.

Therefore, the algebraic expression for "the quotient of 38 and x" is:

38 ÷ x

In this expression, 38 is divided by x, and the result of this division is the value of the expression.

Depending on the value of x, the result will change accordingly.

If x were equal to 2, for example, then the expression would evaluate to 38 ÷ 2 = 19. If x were equal to 5, the expression would evaluate to 38 ÷ 5 = 7.6, and so on.
