Answer:
7.03%
Step-by-step explanation:
The percentage of the life time cost which was the interest is; Choice B; 13.21%
Percentage and InterestSince, 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 = $789.12Hence, 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%Read more on percentages and interest;

The area of the square is
3x2 - 7x + 12. The area of the
triangle is x2 - 8x + 18. Find the
area of the shaded region.
Answer:
Area = 2x² + x - 6
Step-by-step explanation:
The area of the shaded region is the square area minus the triangle area:
[tex](3 {x}^{2} - 7x + 12) - ( {x}^{2} - 8x + 18) \\ {3x}^{2} - 7x + 12 - {x}^{2} + 8x - 18 \\ {2x}^{2} + x - 6[/tex]

Surface Area and Volume of a Cube
Given a cube of side length a, the surface area is:
[tex]A = 6a^2[/tex]
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
Now compute the volume:
[tex]V=13^3[/tex]
[tex]\boxed{V=2197\ cm^3}[/tex]
Answer: a) 2197 cm^3

(x-8)2 – 7 = 25
Factored
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
x = 8 ± 4√2

Answer:
5
Step-by-step explanation:
A proportional relationship has the equation ...
y = kx . . . . . . where k is the constant of proportionality
Solving this equation for k, we get ...
k = y/x
Filling in the given values (x, y) = (4, 20) gives ...
k = 20/4
k = 5
The constant of proportionality is 5.

The truck costs $ 9,068 including a 19% port tax. If the selling price is reduced by 20%. Find out the new car price before tax is added.
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
= $ 1524.03
New price = 7620.17 - 1524.03
= $ 6096.14

Step-by-step explanation:
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

Order the expressions from the least number of terms to the greatest number of TERMS.
Answer:
3x⁹, 2x - 5(3x²), 8x + 2x/3 + 6, x + 3 - y - 6
Step-by-step explanation:
3x⁹ has one term, so it comes first. 2x - 5(3x²) has two terms, so it comes next. 8x + 2x/3 + 6 has three terms and comes next. The last one is x + 3 - y - 6 because it has four terms.
2 divided by negative 1/5
Answer: 10
you have to find a common denominator between two and five which is 10. therefore making the number 2 into the fraction 20/10 and finding the common denominator of 1/5 makes it now 2/10. now divide 20 by 2 which gets you 10. and dividing 10 by 10 gets you. therefore making the new fraction 10/1 which is equal to 10. :)
x + 3x² – 28x
Can you guys help me solve this in ax^2+bx+c
Thank you thank you
Answer:
3x²+(-27x) +0
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
Hence, the required equation is 3x²+(-27x) +0.

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
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)
