Jennifer buys a desk on sale for $478.60. If the regular price was $684.00, what is the percentage of discount?
Answer:
30%
Step-by-step explanation:
Find the percent discount by dividing the change in the price by the original price:
(684 - 478.6) / 684
205.4 / 684
= 0.3
So, the percent discount was approximately 30%
factor completely;
3x^2+4x-7
Answer:
(3x-7) (x+1)
Step-by-step explanation:
3x^2 - 4x - 7
First split the middle term
3x^2 + 3x - 7x - 7
Make into two separate expressions
(3x^2 + 3x) (-7x-7)
Take out what you can
3x (x+1) -7 (x+1)
Now you have your answers
(3x-7) (x+1)
Find the area of this parallelogram. Be sure to include the correct unit in your answer.
Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
Answer:
A = 126 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 14 and h = 9 , then
A = 14 × 9 = 126 cm²
Round 245,675 to the nearest hundred thousand
The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.
What is round off?Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
here, given that,
Round 245,675 to the nearest hundred thousand
we know,
Anything at or above 50 gets rounded up.
49 and below gets rounded down.
so, we get,
here, to the nearest hundred thousand means 675 > 500
so, it will be 5,675 => 6000
we have,
Rounding off 245,675 to the nearest hundred thousand is:
246000
Hence, The solution is, Rounding off 245,675 to the nearest hundred thousand is: 246000.

Find the length of side x in simplest radical form with a rational denominator.
Answer:
x=2√5
Step-by-step explanation:
1st method:
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
2nd method:
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
3rd method:
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5

Mary made 12 bracelets. 9 of those bracelets are the color blue.
What percent of bracelets are blue?
Answer:
75%
Step-by-step explanation:
We know that Mary made twelve bracelets and also that nine of them are blue, we are then asked to find the percentage of the bracelets that are blue.
To solve, first get a fraction of how many of the bracelets are blue. Since there are twelve in total, 12 will be our denominator, and since 9 are blue, 9 will be our numerator.
[tex]\frac{9}{12}[/tex]
Now to turn this into a percentage, we need to reduce this fraction to the lowest we can. Both numerator and denominator are divisible by 3, so do as followed :
[tex]\frac{9/3}{12/3}[/tex]
[tex]\frac{3}{4}[/tex]
Divide 3 by 4 :
[tex]3/4 = 0.75[/tex]
Multiply 0.75 by 100 to get our percentage :
[tex]0.75 * 100 = 75[/tex]%

The area of a rectangular park is 300 sq.M. If the length of the park is 25 m, find the breadth. *
Answer:
Breadth = 12 m
Step-by-step explanation:
Area of a rectangle is given by the formula,
Area = Length × Width
Value of area and length of the rectangular park has been given in this question.
Therefore, by substituting these values in the formula,
300 = 25 × Width
Width = [tex]\frac{300}{25}[/tex]
= 12 m
Therefore, width or breadth of the rectangular park will be 12 m.
Evaluate. 2.2^3 . 2^-5 .2^-1
A. -4
B, -8
C. 1/4
D. 1/8
Answer:
Step-by-step explanation:
2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 )
= 2^( 3 - 6 )
= 2^- 3
= 1 / 2^3
= 1 / 8
If
2 . 2^3 . 2^- 5 . 2^- 1
= 2^1 . 2^3 . 2^- 5 . 2^- 1
= 2^( 3 - 5 - 1 + 1 )
= 2^( 3 - 5 )
= 2^- 2
= 1 / 2^2
= 1 / 4

Which statement identifies how to show that j(x) = 11.6ex and k(x) = In (StartFraction x Over 11.6 EndFraction) are inverse functions?
Answer:
The answer is "It must be shown that both [tex]j(k(x))\ and \ k(j(x))=x[/tex]"
Step-by-step explanation:
Given:
[tex]j(x) = 11.6 e^{x} \\\\k(x) =\ln\frac{x}{11.6}[/tex]
To show that both are equal functions, and show that both[tex]j(k(x))\ and\ k(j(x)) =x,[/tex]
For [tex]j(k(x));[/tex]
[tex]j(k(x)) = j[(\ln \frac{x}{11.6})]\\\\j[(\ln (\frac{x}{11.6})] = 11.6e^{\ln (\frac{x}{11.6})}\\\\j[(\ln \frac{x}{11.6})] = 11.6(\frac{x}{11.6})\\\\[/tex](The natural logarithm is canceled by exponential function)
[tex]j[(\ln \frac{x}{11.6})] = 11.6 \times\frac{x}{11.6}\\\\j[(\ln \frac{x}{11.6})] = x\\\\j[k(x)] = x\\\\for\ \ k[j(x)]:\\\\k[j(x)] = k[11.6e^x]\\\\k[11.6e^x] = \ln (\frac{11.6e^x}{11.6})\\\\k[11.6e^x] = \ln(e^x)[/tex]
Its natural logarithm leaving x will nullify expanding universe.
[tex]k[11.6e^x] = x\\\\k[j(x)] = x[/tex]
In the question, it is seen that[tex]j[k(x)] = k[j(x)] = x[/tex], shows that the functions [tex]j(x) = 11.6 e^{x} \ and \ k(x) = \ln \frac{x}{11.6}[/tex] is inverse functions.

The radioactive substance polonium-210, with a half-life of 138.39 days, is present in tobacco. Suppose that the soot in an ex-smoker's lungs contains 100 milligrams of polonium-210. How much radioactive polonium will remain after one year of not smoking
Answer:
16.07 milligrams
Step-by-step explanation:
From the question,
Using the formula of radioactive decay,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.
Make R' the subject of the equation
R' = R/(2ᵃ/ᵇ)................ Equation 2
Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days
Substitute these values into equation 2
R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)
R' = 100/(6.222)
R' = 16.07 milligrams of plonium-210

Trig homework. Find the two missing sides and write your answer as in simplified radical form.
Answer:
u = 8, v = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{2} }{u}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
u = 8
The triangle is right isosceles with legs congruent, so
v = 4[tex]\sqrt{2}[/tex]
The area of a rectangular field is 7371 m2. If the length of the field is 91 meters, what is its width?
Answer:
81 m
Step-by-step explanation:
From the question given above, the following data were obtained:
Area (A) = 7371 m²
Length (L) = 91 m
Width (W) =?
Area of a rectangle is given by the following equation:
Area = Length × Width
A = L × W
With the above formula, we can obtain the width of the rectangular field as follow:
Area (A) = 7371 m²
Length (L) = 91 m
Width (W) =?
A = L × W
7371 = 91 × W
Divide both side by 91
W = 7371 / 91
W = 81 m
Thus, width of the rectangular field is 81 m

Answer:
There are 3,750 sweets in the carton
Step-by-step explanation:
Here, we want to get the total number of sweets
From the question, we have that individual box have 50 sweets
So the number of sweets in the carton have 75 boxes will be the product of the number of sweets and the number of boxes
Mathematically, we have this as;
50 * 75 = 3,750 sweets
