Harriet used her credit card to buy a $779 laptop, which she paid off by making identical monthly payments for two and a half years. Over the six years that she kept the laptop, it cost her an average of $0.36 of electricity per day. Harriet’s credit card has an APR of 11.27%, compounded monthly, and she made no other purchases with her credit card until she had paid off the laptop. What percentage of the lifetime cost of the laptop was interest? (Assume that there were two leap years over the period that Harriet kept the laptop, and round all dollar values to the nearest cent.)
a.
7.03%
b.
13.21%
c.
11.27%
d.
6.97%

Answers

Answer 1

Answer:

7.03%

Step-by-step explanation:

Answer 2

The percentage of the life time cost which was the interest is; Choice B; 13.21%

Percentage and Interest

Since, the APR is compounded monthly at an Annual percentage rate, APR of 11.27%, it follows that;

A = 779(1+0.1127)^(2.5)

Hence, the total amount to be paid over the two and half years is; A = $1017.38.

Hence, the interest is given as;

Interest = $1017.38 - $779 = $238.38.

The cost of electricity bill at $0.36 per day, (Assuming that there were two leap years over the period).

Cost = 0.36((4×365) +(2×366))

Cost = $789.12

Hence, the lifetime cost of the laptop is; $789.12 + $1017.38 = $1806.5.

Ultimately, the required percentage is;

($238.38/$1806.5) × 100% = 13.21%

(x-8)2 – 7 = 25
Factored

Answers

Answer:

x = 8 ± 4√2

Step-by-step explanation:

(x - 8)² - 7 = 25

Add 7 to both sides.

(x - 8)² = 32

Take the square root for both sides.

x - 8 = ±√32

Add 8 to both sides.

x = 8 ±√32

Simplify √32

√32 = √16 · √2

√32 = ±4√2

Suppose the amount of a popular sport Drink in bottles leaving the Filling machine has a normal distribution with me 101.5 ml and standard deviation 1.6 if 36 bottles are randomly selected, find the probability that the mean is less than 102.1ml

Answers

Answer:

0.98778

Step-by-step explanation:

Given :

Mean, m = 101.5

Standard deviation, s = 1.6

Sample size, n = 36

Sample mean, x = 102.1

P(x < 102.1)

Zscore = (x - m) / s/sqrt(n)

Zscore = (102.1 - 101.5) / (1.6/√36)

Zscore = 0.6 / 0.2666666

Z = 2.25

P(Z < 2.25) = 0.98778 (Z probability calculator)

Similar Triangles

If two triangles are similar, then:

* All the corresponding side lengths are proportional by the same scale factor

* All the internal angles are congruent.

The image provided in the question has two similar triangles TYZ and TWX. We have completed the shape with a variable p =TZ, whose value will be determined by applying the first similarity condition above.

The ratio between the heights is 20:16, and the proportion between the bases is (6+p):p, thus:

[tex]\displaystyle \frac{6+p}{p}=\frac{20}{16}=\frac{5}{4}[/tex]

Cross-multiplying denominators:

4(6 + p) = 5p

24 + 4p = 5p

Solving for p:

p = 24

Then, TZ = 24

Step-by-step explanation:

The given expression is :

x + 3x² – 28x

We need to solve this in the form of ax²+bx+c.

we can write the given expression as :

3x²-28x+x = 3x²-27x

= 3x²+(-27x) +0

If we compare the given expression with the general expression, we find that,

a = 3, b = -27 and c = 0

Surface Area and Volume of a Cube

Given a cube of side length a, the surface area is:

The volume is calculated as:

[tex]V=a^3[/tex]

It's given the surface area of a cube:

[tex]A=1014\ cm^2[/tex]

We can find the side length a by solving for a:

[tex]\displaystyle a=\sqrt{\frac{A}{6}}[/tex]

[tex]\displaystyle a=\sqrt{\frac{1014}{6}}[/tex]

[tex]\displaystyle a=\sqrt{169}[/tex]

a = 13 cm

Answers

Answer:

$ 6096

Step-by-step explanation:

Let the cost of truck = x

x+19% of x = 9068

x + 0.19x = 9068

1.19 x = 9068

      [tex]x = \frac{9068}{1.19}[/tex]

    x = 7620.17

Reduction = 20% of 7620.17

                 = 0.20 * 7620.17
